Starting from the Greyhound, seventy-two changes.

In the Liangjie Mountains, the forests have turned green, and the sea of ​​trees is surging like waves in the night wind.

Whoosh!
Chen Ku used the earth escape technique and appeared directly at Liangjie Mountain, more than 120 miles north of Baojiao County.

As the border dividing the two countries of Ji and Yuan, the Liangjie Mountain Range stretches for more than 3,000 miles, like a giant mountain dragon crawling on the earth.

The tall mountains not only blocked the cold air and sandstorms blowing southward from the northern Yuan Kingdom, but also blocked the warm and humid climate from the southern Ji Kingdom, resulting in a huge difference in scenery and temperature between the two countries.

Sniff~
Chen Ku twitched his nostrils slightly and could already smell the scent of a large number of humans five or six miles away. This smell was very common in the laboring area outside the city of Baojiao County, and they were usually the laborers.

"That place should be the entrance to the underground palace where the Xia Wang treasure is buried that Shangguan Yun and Sui Youpai excavated."

He did not smell Sui You among the thousands of people ahead. He thought that he probably just came here to supervise the work and check the progress from time to time, and he did not stay there all day.

In this way, Chen Ku had the confidence to sneak into the past boldly:
"Go check it out."

Immediately, his body shrank and turned into a small bee. He used the Nine-Colored Deer's "Nine-Colored Light Technique" to hide his body, and then used the earth escape technique to shrink himself into the ground.

In less than half a cup of tea, they had reached the underground tunnel.

……

In the underground tunnel.

"Brother Niu, Brother Niu fainted from exhaustion."

Someone saw a strong man who was digging in the tunnel suddenly fall to the ground and couldn't help but shouting: "What happened?"

However, just as he was about to step forward to investigate, he heard the sound of a whip breaking through the air, and then with a "snap", it hit his shoulder hard.

"what!"

The corvée laborer named Xin Xiaonian screamed and immediately stepped back in fear, then he heard the whip-wielding supervisor speak coldly:
"What? Do your job."

Xin Xiaonian didn't dare to look up at the moment. He quickly grabbed the pickaxe, lowered his head and started working trembling with fear.

After the whip-wielding supervisor waved away the others, he looked at the unconscious strong man and said coldly and impatiently, "Come, two people, carry him away. Don't delay the progress of the project."

Immediately, two supervisors with knives came forward, lifted up the unconscious worker, loaded him into a mine cart, started the mine cart, and drove it to an unknown area.

hum~~
Chen Ku transformed into a bee and disappeared, flapping his wings. He happened to stop beside the mine cart that was moving away. He saw the whole scene clearly and was slightly shocked.
"Were all these people recruited by Shangguan Yun to work as laborers to dig the underground palace? But I haven't heard of a large number of people going missing in Baojiao County..."

After thinking about it, I seemed to have thought of a piece of information.

It seems that just before the New Year, Baojiao County had collected "corvée taxes" and forcibly conscripted people to build a water conservancy dam. That forced corvée was about more than a thousand people. It turned out that...

They all came here.

Chen Ku couldn't help thinking:

"Shangguan Yun is indeed the county magistrate, the master of a county. With a single order, he can secretly recruit thousands of people to dig an underground palace for him."

Looking inside the underground palace corridor, the supervisors would beat and scold the laborers at will. It was common for the laborers to die of exhaustion due to the unbearable hard work. I couldn't help but think of the time when I was in Dachen Village. I was almost forced to perform labor service because I could not pay the autumn tax.

I sighed in my heart.

It didn't look at it for long, but just flapped its wings and kept moving forward in the corridor.

On the way forward, he kept passing by laborers who were carrying loads of stones and soil, lined up in long queues. Surrounding them were guards holding knives and drinking, with a guard post every fifty steps.

"These guards on duty don't look like runners from Baojiao County, but they all seem to have martial arts skills, and at least some have internal energy cultivation..."

Chen Ku began to doubt the origins of these guards on duty:
"Is this Shangguan Yun's personal power?"

It seems that I have heard that before Shangguan Yun came to Baojiao County to take office as the county magistrate, he was the leader of a huge gang in Qiulong Prefecture. Later, somehow, he got an official position.

If these people are really Shangguan Yun's personal force, Chen Ku can't help but feel more pressured by Shangguan Yun's overall strength.

He is a man who is good at dealing with both black and white matters. He can mobilize officers and soldiers from Baojiao County and secretly have a gang serving him. If you really meet such a person, if you cannot kill him in a one-on-one fight, his huge power can easily kill all his enemies.

Keep flying forward.

At the entrance of the corridor ahead, there were several small caves opened up on the left and right, and someone was talking inside:
"Uncle San, you said that when this underground palace is opened, there won't be any zongzi, right? This underground palace is so large that it looks like it is of an imperial scale. If there really is a corpse that turns into a zongzi, the power would be immeasurable."

Inside the cave, there was a young man with a ponytail on his head. He looked very refined. He asked his senior in the same field, "Third Uncle":
"Should we prepare early and get some black donkey hooves or something like that?"

The middle-aged man named Uncle San was smoking a pipe, looking at his nephew, and sneered: "You said it yourself, such a large underground palace, the entrance alone was rammed with countless stones. It is estimated that the scale of the underground palace is at least the size of a mountain, and the interior is hollowed out. If there are really zongzi, can the black donkey hoof deal with it?"

The old man took a puff of his cigarette, and was slightly shocked as he spoke. As a famous tomb robber in the Qiulong generation, he was nicknamed "Master Yao". Over the years, he had seen large tombs before, but this was the first time he had seen an underground tomb of this scale.

"Then, this trip...will end in death." The young man was very worried.

"What are you afraid of? We are only responsible for helping that gentleman open the entrance to the underground palace, and we are not going in. If we really want to go in, we have the support of that gentleman and the masters of Tiangong Mansion."

……

Tiangong Mansion?
When Chen Ku heard these three words, he had never heard of them before.

But when he looked into the cave on the other side, he saw many mechanical bronze men and puppets inside. There was a middle-aged man with mechanical hands in his arms, who was fully devoted to the creation of a mechanism.

"Is this the master from Tiangong Mansion? It sounds like he is a master of mechanical devices similar to the Mohist School in the previous life?"

Chen Ku recalled the inheritance of the Kirin blood memory. It seemed that on that route map, there were many symbols of mechanical figures, which vaguely symbolized the existence of a similar guardian.

I suddenly remembered this information.

Then it flapped its wings and flew towards the end of the tunnel. At the end of the tunnel, Chen Ku finally discovered the way these people were digging. They were actually digging stones. There were dozens of people holding diamond drills, digging at the stones in the soil...

Chen Ku finally understood why his third uncle said that this underground palace was hollowed out of a mountain and that the rocks really served as barriers. No wonder it took Shangguan Yun so long to dig through 90% of it after he captured the Xu family.

It's really 'opening up the mountain'.

Chen Ku transformed into a little bee and flew over the heads of a group of laborers and came to the stone wall at the end. He looked carefully and found that these stones were all neatly stacked together like huge stones like a pyramid.

But, seeing the end, I was delighted:
"There are gaps. It's good to have gaps!"

Since the stone palace was built on the outside of the mountain by external force, there must be gaps between the stones. The gaps mean that he can use the earth escape technique to get in.

swoosh~
A laborer was digging a stone when he suddenly saw something blurry in front of his eyes. It seemed that a piece of the stone had come loose...

……

Swish!Swish!Swish!
Chen Ku used the Earth Escape Technique to continuously find gaps in Shangguan Yun's last stone barrier, which was only 10% of the way to his death, and escaped into it continuously...

With a body the size of a small bee, he was trying to find a gap among the ochre-colored boulders that were dozens of feet in radius. If his mental memory wasn't strong enough, he wouldn't be able to remember the route.

This feeling is just like a small person entering a huge maze built by a giant. Not only will he get lost, but the most important thing is the terrible mental depression.

…………

call!call!
Not knowing how much time had passed, Chen Ku estimated that he had been inside for at least half an hour. Suddenly, there was a light in front of him... Then, his small body flew out and immediately sank into a silver ocean.

[Beside the figure owner, there is an item that meets the conditions for practicing the sixth transformation diagram: ten thousand kilograms of mercury]

[Whether to choose sacrifice]

……

When Chen Ku entered this silver ocean, his first feeling was that his body was instantly stimulated to display the abilities of the five-colored peacock: [Not damaged by metal] and [Not drowned by water]

Immediately, it transformed into a five-colored peacock and fled towards the ocean surface.

Less than a moment.

I saw a colorful peacock flapping its wings and flying out in this huge silver ocean.

This one flew out.

Chen Ku finally understood why the transformation diagram reminded him that there were things around him that met the conditions for practicing the sixth transformation diagram. He suddenly saw that beneath him was an ocean of mercury, like a huge lake, blocking the huge stone wall. On the shore at the end of the lake was a stone pillar gate that looked like something from a myth, and behind the gate was a huge cave, about ten feet high.

"This amount of mercury... It's almost like the underground palace of Qin Shi Huang in the legend of the past life!"

He was shocked.

The mercury in the lake is like that in a lake. If it were converted into silver, God knows how much it would be worth!
Only at this time did he have the mind to look at the reminder of the change chart.

Upon seeing this, he was shocked to discover that because there was so much mercury here, even the cultivation conditions of the seventh picture were triggered.

[Beside the figure owner, there is an item that meets the conditions for practicing the seventh transformation diagram: 100,000 kilograms of mercury]

[The seventh transformation diagram practice conditions: 100,000 catties of mercury, 100,000 ounces of red gold, 10,000 catties of golden jade, 10 paths of five-level evil spirits, one unique skill to perfection, and a piece of spiritual jade]

(Note: After completing the seventh picture, the second great magical power of the master of the picture, the "Demon Summoning Banner", will be awakened)
Chen Ku was surprised and shocked.

It was known before that the transformation diagram would add an extra magical power every 'three' or 'seven' diagrams, and his fetal transformation and body refining was achieved in this way.

Now, the information of the seventh picture has finally been revealed.

"Demon-summoning banner?"

The first thing that came to Chen Ku’s mind was the supreme magic weapon that Queen Nuwa used to command the monsters. However, isn’t this a magic weapon? How did it become a magical power?

"Demon Summoning Banner? What does it do? Can it summon a group of demons to serve me as their master?"

Too little information to make a comment.

He had to look carefully at the training conditions of the seventh transformation diagram.

"pure gold?"

Chen Ku took a breath of cold air.

With his current social status, he can also understand the currency of the upper class. As the saying goes, 'No gold is pure, no man is perfect', pure gold is something even rarer than gold. Generally speaking, it is not formed naturally, but is made by refining. It is mainly used by some Taoists when making elixirs.

When gold is burned to a sufficiently pure degree, it becomes 'red gold' that can be used as medicine.

The medicine mentioned here refers to "pills".

The "golden elixir" made by refining metals such as gold, silver, lead and mercury.

There are similar methods of alchemy in Yaowang Hall, but they are far from using "medicine" as precious as red gold. The main reason is that Yaowang Hall does not have any "elixir recipe" related to red gold.

"Red gold is just like silver essence. I estimate that it takes ten taels of gold to refine one tael of red gold. One hundred thousand taels of red gold... wow..."

Chen Ku felt that he would never be able to earn so much money in his entire life in Baojiao County.

As for the gold silk jade, it is even more expensive.

As for the Lingyu, Chen Ku had never even heard of it.

can.

Look at one of the conditions in the sixth or seventh picture that has been met.

Mercury, ten thousand catties of mercury, one hundred thousand catties of mercury...

Around the perimeter of this underground palace, they simply rebuilt a 'moat'-like anti-theft measure.

"I don't think I can earn the gold and silver precious metals needed for the transformation diagram in my lifetime with ordinary means, but... if I can get the 'King of Heroes' treasure' in this underground palace, it will be completely different."

Chen Ku looked at the mercury ocean below and said without hesitation:
"Sacrifice! Sacrifice me! Sacrifice as much as you want!"

boom!
boom!
Suddenly, along with the "void swallowing" of the transformation diagram, forty to fifty tons of mercury disappeared from the mercury lake that looked like an ocean...

The height of the entire mercury lake dropped by about one foot.

[The owner of the picture has met the cultivation conditions of the sixth transformation picture 5/6]

[The owner of the picture has met 1/6 of the conditions for practicing the seventh transformation picture]

Chen Ku saw that the sixth transformation diagram was only one step away from awakening, and it was only missing one last condition: "a transformation of the highest quality in the fourth realm."

at this time.

He looked towards the entrance of the underground palace, very cautiously, because at the entrance, stood a three-meter-tall bronze giant, holding a Xuanhua axe in his hand, as majestic as a god.

"That……"

If he hadn't overheard the uncle and nephew who worked as tomb robbers outside the underground palace entrance, Chen Ku might have thought it was a statue, but now he was very sure:
"It's a bronze mechanical puppet!"

Thinking that this underground palace was built by a hero of at least the Fourteenth Realm, the strength of the bronze puppet he left behind...

Chen swallowed bitterly.

Guess in my mind:

"Seventh realm? Eighth realm? Ninth realm? Or higher?"

But, now that we are here, it would be a joke if we were trapped in this puppet at the gate.

"Let's try and see if the clone can get through..."

Chen Ku stretched out his palm, blew a breath, and transformed into a bee. He asked the little bee to explore the way first. If the bee could pass, then he could pass too.

If the bees cannot pass, then they will only lose a bee incarnation. (End of this chapter)
