Immortal cultivation starts with copying.

At first, Chen Yunhao thought Du Xiangyu was so naive. As the saying goes, only by attacking as defense can you survive in desperate situations.

If you just act like a coward and rely on passive defense to save your life, the only outcome is death.

Unfortunately, he guessed wrong. Du Xiangyu wanted to use these protective measures to delay time, and eventually he would display his so-called great supernatural powers.

Just use it. No matter how powerful the sword formation is, it takes time to strangle the opponent, not to mention the turtle shells layered on the left and right.

Now that things have come to this, Chen Yunhao simply gave him some time to see what kind of extraordinary magical powers he could display and broaden his horizons.

Du Xiangyu took out a small jade bottle, flicked the bottom of the jade bottle lightly, and more than thirty drops of essence and blood flew out.

Because of the formation, Chen Yunhao couldn't sense whether it was human blood or monster blood.

I saw more than thirty drops of essence and blood floating in the air. Du Xiangyu quickly pinched various spells with his hands and muttered something.

This method is indeed time-consuming to perform, and after a long while, the thirty or so drops of essence and blood suddenly disappeared.

From the place in the air where the essence and blood disappeared, there was a spatial fluctuation, rolling like a wave.

Seeing this, Du Xiangyu hurriedly threw out another thirty drops of essence and blood, and performed a set of magic spells according to the law.

After the next thirty or so drops of essence and blood disappeared, the fluctuations in that space became stronger, and a crack as long as an arm slowly appeared.

The gap in space was dark, and a trace of cold and gloomy energy emerged.

At this moment, Chen Yunhao, who was outside the formation, felt a little alert.

He hurriedly ordered the army waiting below to start attacking the Qingyun Mountain team and to resolve the war as soon as possible to avoid any further complications.

In addition, just in case, Chen Yunhao secretly set up the Earthly Evil Falling Star Formation outside the sword formation, but it has not been activated yet.

Du Xiangyu, who was trapped in the sword formation, cast a spell for the second time, but in the end, he only created a crack as long as his arm.

This was somewhat beyond his expectations. It was the first time he had cast this kind of spell and he had no experience. It was completely different from what he had expected.

After that, Du Xiangyu gritted his teeth, took out the small jade bottle again, and poured out all the remaining blood and essence in the bottle, which was about twenty or thirty drops.

Chen Yunhao saw it clearly from outside the sword formation and saw that the amount of blood and essence splashed out three times was quite a lot.

With his cultivation level of Lianxu, the amount of essence and blood that can be extracted from his whole body is only about a hundred drops. I guess the source of that essence and blood is not easy!

After re-casting the spell and mantra, the dark space crack expanded to less than half a meter.

Just when Du Xiangyu's face turned pale and he was at a loss, suddenly two dry fingers stretched out from the crack in the space.

That’s right, there are just two of them, and these two have filled up the entire space crack.

The two fingers pulled upwards with force, and the space crack suddenly expanded, expanding to nearly fifty feet high.

A huge amount of dark wind gushed out from the huge space crack, accompanied by the howling of ghosts and wolves.

Finally, a tall and gloomy figure squeezed out from the crack in space.

This is a creature similar to dry bones, but it still has flesh and skin, tightly attached to the bones, looking like a living dead.

"The summoning technique actually summoned a ghost general from the underworld...!"

Chen Yunhao was also a little shocked. He had seen simple records in some classics.

It is said that there is a magical power called summoning, which can summon powerful beings from the underworld or even the demon world to come, but the price to pay is too high.

Moreover, this summoning technique is said to be rejected by the entire human race, and no one is allowed to practice it privately. It should have been an extinct magical power long ago.

“Hehehe… It’s been so many years since I tasted human blood…!”

The huge ghost general had a pair of deep-set eye sockets, in which were not normal eyeballs, but two balls of ghost-like things that kept flashing.

The ghost general of the underworld let out a hoarse laugh that made people break out in a cold sweat.

"Human, that little bit of essence and blood is not enough for me to use, you can come and make up the number!"

The ghost general from the underworld looked down at Du Xiangyu, stretched out a giant hand and grabbed him.

There was only a slight popping sound, and layer after layer of turtle shells on Du Xiangyu's body were directly shattered, and even the protective spiritual shield lost its spirituality.

"Senior, I summoned you out. There's blood food all over the place. You can't eat me...!"

Du Xiangyu's face turned pale with fear and he struggled repeatedly, but to no avail.

This gigantic ghost general from the underworld displayed the strength of a combined body.

In the underworld, a ghost general is equivalent to a fusion, and above them there are ghost kings and ghost emperors, corresponding to the Mahayana and the tribulation.

In front of the ghost general, Du Xiangyu was frightened. Not wanting to become the ghost general's food, he wanted to self-destruct, but found that his body could not move, and only his thoughts could move.

Du Xiangyu watched helplessly as the ghost general stuffed himself into his mouth. Then darkness came over him and he disappeared forever.

Chen Yunhao's heart was also beating wildly outside the sword formation. He had encountered the combination of humans before, and he had even encountered the combination of demons.

However, the ghost general from another world brought him great pressure, causing his heartbeat to accelerate and his sense of crisis to explode.

But he couldn't escape alone, because there were thousands of Taiyi Sect disciples below, fighting with the Qingyun Mountain disciples.

Countless thoughts flashed through Chen Yunhao's mind in an instant, and finally he made up his mind. Damn it, he had two lives, so what was there to be afraid of? But he could not bear the stigma of escaping from the battlefield.

Besides, this summoning technique is to summon powerful beings from other worlds to cross over, and it has many limitations. He will have to return to the underworld within a certain period of time, but he doesn’t know how long it will take, so he can only try his best to persevere.

"Why are you panicking? Activate the formation outside. I'm going to make sure this big guy never comes back...!"

Perhaps the spirit of the weapon sensed Chen Yunhao's accelerated heartbeat, and it, which had not appeared for a long time, sent a message to Chen Yunhao in his mind.

Chen Yunhao also wanted to slap himself. It is easy to make mistakes when you are in a hurry. It seems that his character has not been cultivated enough.

How could he forget his biggest trump card and backer at this critical moment?

Since the spirit of the weapon said so, there must be no problem. For a moment, Chen Yunhao felt relieved.

Although he had a lot of thoughts in his mind, Chen Yunhao's hands did not stop moving. He quickly activated the Earthly Evil Falling Star Formation, and activated it with all his strength, reaching its maximum power.

The entire formation completely concealed the space within a radius of several thousand feet, and not even a trace of spiritual power could be seen.

Although the fifth-level formation corresponds to the fusion, Chen Yunhao's cultivation is relatively low, and he is completely unable to trap the Netherworld Ghost General using the fifth-level formation.

His main purpose in activating the formation was to create conditions for the spirit of the weapon, to conceal the secret as much as possible, and to prevent the spirit of the weapon from leaking out.
