Immortal cultivation starts with copying.

In recent years, Taiyi Sect has been recruiting disciples to expand its strength. Although it has incorporated the Zheng family's markets and industries, its income can barely break even.

Chen Yunhao was quite aware of this, so he tried his best to collect high-grade spirit crystals on his way back. At present, he has collected nearly 500 high-grade spirit crystals, which is enough for him.

Chen Yunhao has his own quiet room. As soon as he comes back, he closes the door and does not come out for more than ten days.

He shared all the memories in his mind about the underworld with his clone, letting the clone know what the key things to do after going to the underworld are.

In addition, there are various elixirs, spiritual materials, various magic weapons and even a few spiritual tools. In short, all kinds of resources fill up a storage bracelet.

The clone will use these spiritual materials to set up a reception formation in the lower world, and there will be two formations at a time.

The first formation is to guide people coming down from the upper realm, and the second formation is to echo the guiding formation of the upper realm so that the ascending monks from the lower realm can accurately find the upper realm.

These are two medium to large formations, requiring a large amount of materials, which Chen Yunhao had collected decades ago.

After explaining everything that needed to be explained, Chen Yunhao was most worried that since there was no formation to lead people to the lower realm, he could only rely on his clone to go through the vast void alone to find the Tianyuan Realm.

In addition, Chen Yunhao had already given half of the iron rod that he brought up from the lower realm to his clone. As long as he was within 10 million miles of the Tianyuan Realm with the iron rod, he could sense it.

All is ready except for the opportunity.

Only Master Liu and Chen Yunhao knew how to enter and exit the mountain where the underground formation was located. Even Master Liu's disciples were not clear about it, and they didn't even know that such a mountain existed.

Chen Yunhao had learned about the method of activating the formation from Master Liu decades ago.

This was the original secret of the Five Thunder Sect and could only be passed down by the Sect Leader himself.

In fact, Chen Yunhao could activate the world-breaking formation by himself, and his real body did not go down to the mortal world.

I'm alone, and it's my first time operating this, so I'm always afraid something might go wrong. Having Master Liu helping me makes me feel more at ease.

Chen Yunhao made an appointment with Master Liu and together they entered the mountain where two large formations were set up.

The first thing to activate is the world-breaking formation, and the clone must be sent down to the world first.

As for the guiding formation, there is no need to rush. It won’t be a problem if it is delayed for three or five days.

As soon as the two of them entered the mountain, Chen Yunhao flicked his sleeves and his clone appeared beside him.

"Greetings, Senior Brother Liu...!"

Chen Yunhao's clone smiled and saluted with his fists clasped.

Master Liu was stunned. He knew that Chen Yunhao was going to use the Boundary Breaking War to go to the lower realm, but he had never told him that he would use a clone to go down.

"A true clone, Junior Brother Chen has great skills!"

Master Liu looked Chen Yunhao's clone up and down carefully.

Only at this moment did he truly feel that Chen Yunhao was truly mysterious and extraordinary, with extraordinary means, and was not an ordinary cultivator!

This technique of clone is not about creating a puppet. The clone that can travel between the two worlds is almost the same as the real person. This is something that only a great Mahayana cultivator who has transcended the tribulation can accomplish.

Chen Yunhao smiled and didn't say anything. It was better to remain mysterious. There was no point in saying too much.

Then Chen Yunhao flicked his hands again, and one hundred and eight high-grade spirit crystals fell one by one on the world-breaking formation.

"Thank you, Senior Brother, for protecting me. If there is anything wrong, please remember to remind me in time."

Chen Yunhao nodded at Master Liu.

Master Liu silently took two steps back and just nodded.

Chen Yunhao looked at his clone again. There was no need for the two of them to say a word to each other. They were one and the same, so naturally they had a mutual understanding.

The clone had a calm expression as he slowly walked into the center of the Boundary Breaking Array, looked around, and then nodded to the original body, indicating that everything was ready.

Then Chen Yunhao was seen making hand gestures with his hands in front of the formation, and rays of spiritual light shot into the world-breaking formation.

As the spiritual light in Chen Yunhao's hand continued to penetrate the formation, the Boundary Breaking Formation slowly began to emit spiritual light.

The one hundred and eight high-grade spirit crystals burst out with spiritual light one after another like lit candles.

After all, the Great Boundary Breaking Formation is a large-scale formation, and it is very time-consuming and labor-intensive to activate it.

Chen Yunhao kept making hand gestures with his hands, and he had been doing so for half an hour. The spiritual light on the world-breaking formation became stronger and stronger, and the light was so bright that the clone in the center of the formation was almost invisible.

Beads of sweat had already appeared on Chen Yunhao's forehead, and more than half of his magic power had been consumed.

Suddenly, a buzzing sound came from the Boundary Breaking Formation, and a white light burst out, leaving only white light in front of Chen Yunhao's eyes.

At this moment, Chen Yunhao put away the magic spell and the formation was activated.

The whole process only lasted for half a cup of tea. When the white light dissipated, the entire formation returned to calm.

Looking at the center of the formation again, the clone had long disappeared, and the 108 high-grade spirit crystals had all turned into powder.

The Great World-Breaking Array is indeed not something that ordinary sects can afford. The spirit crystals used to activate it just once are enough for a Void-Refining cultivator to accumulate in half a lifetime.

After the clone broke through the boundary, Chen Yunhao could no longer control what happened next. Even if they were one body, he could not sense any trace of it because they were separated by two realms.

After resting for two days, Chen Yunhao began to activate the guiding formation.

The guiding formation also needs to be inlaid with high-quality spirit crystals, but it can be used repeatedly many times, which is much more economical than the boundary-breaking formation.

Let’s not talk about how Chen Yunhao arranged things in the spiritual world for now, let’s just say that his clone was standing in the world-breaking formation and was blinded by the dazzling light.

Then he felt his body being pushed out by a huge force. The force was so strong that he could hear cracking sounds from the pressure on his body.

Although the clone was made using various spiritual objects, the strength of its physical body is far inferior to that of the original body.

But fortunately, the clone held on, mainly because of the oppressive force of the boundary force at the moment of breaking through the boundary.

Once you break through the boundary and enter the void, there will be no such pressure.

When Chen Yunhao could see again, he had already entered the void.

There is a difference between emptiness and void. There is a kind of emptiness called the state of nirvana, where there is nothing, no sound, no light, no wind, and no air, only nirvana.

The other kind of void is the space between realms, just like the void that Chen Yunhao is entering now.

All you can see are twinkling stars, and each star is a world.

Some, like the Tianyuan Realm, are the realm of immortal cultivation, some are the realm of the dead, and some are purely the realm of mortals. In short, there are thousands of realms and thousands of different kinds.

Chen Yunhao took out half of the iron rod, closed his eyes and sensed it, but perhaps because the distance was too far, he felt nothing.

Without the guidance of the guiding formation, he could not use the method of space travel. Now the only way was to fly to the nearest starlight.
