In the army of gods, Cheng Bo is also wantonly harvesting the lives of demon soldiers, and now even if he does not become a prisoner, he also has the strength of the peak of the late stage of the gods.

Therefore, mixed in with a group of gods, his record is not conspicuous.

And Yun Na stood beside him, cooperating with him to kill the demon soldiers, but the emperor was quite violent, and the huge golden hammer kept picking up and smashing, and each bombardment could destroy thousands of demon soldiers.

Speaking of Qing Yun, she commanded a crimson divine sword, and the entire divine sword had turned into a crimson phantom, traveling on the battlefield faster than lightning, killing a demon general in the demon army.

As for Zong Shan, he controlled two black mountain seals, and when they fell with a bang, they could take the lives of hundreds of demon soldiers.

Although the number of millions of demon soldiers is large, these gods are all ruthless characters who have experienced a hundred battles, and they are not enough to kill, so in less than a few breaths, the million demon soldiers were slaughtered by thousands of gods.

Therefore, the battlefield is full of strong demonic essence, but Cheng Bo does not dislike this, and devours the glorious masterpiece of the rune in the sea of knowledge, constantly pulling the demonic essence around him into refining, turning it into a stream of pure life essence to feed himself.

Therefore, after a battle, Cheng Bo not only did not consume, but his aura became a little stronger.

"Kill!"

A total of four million demon soldiers on the left and right flanks were finally killed, and the army of gods was directly divided into two and attacked, which was tragic and bloody.

Although during the battle, Cheng Bo had been paying attention to the situation of the Outer Heaven Demon Camp.

However, in a few breaths, another army of extraterrestrial demons numbering tens of millions quickly advanced towards this side.

"Gradually retreat towards the banks of the Misty River!"

At this time, Cheng Bo's voice sounded in his mind.

So, the army of the gods fought and retreated.

But the Outer Demons seemed to have insight into their plans, and more than 100 demon commanders led tens of thousands of demon generals to cut off their way.

Suddenly, Cheng Bo's heart froze, and he was faintly uneasy, the demons outside the sky seemed to intend to eat the two brigades on the side of the gods.

Soon, tens of millions of extraterrestrial demons were killed.

Although these demon soldiers are just delivering food in front of the gods, it is undeniable that under the attack of more than 13 million demon soldiers, the army of gods has lost its advantage and has fallen into a bitter battle.

There were even several deities in the early and middle stages of the first rank who were injured.

Fortunately, there are no deaths for the time being.

Moreover, Cheng Bo also found that it was difficult to see the demon generals in the army of demon soldiers, and it was obvious that the demon side outside the sky regarded these demon soldiers as consumables.

on this.

Cheng Bo was a little puzzled, whether the number of demons outside the sky was huge and they were not afraid of damage, or whether they were not afraid of consumption at all.

To this end, he intends to intercept the memories of the demon soldiers, and perhaps discover their secrets.

"What's going on?"

After learning about the memories of several demon soldiers, Cheng Bo's brows were furrowed, because the memories of these demon soldiers were quite short, and the memory of the longest demon soldier was only three years.

This made Cheng Bo see the evil demons outside the sky, although these demon soldiers are all existences that can be killed in the eyes of the gods, but after all, they have the strength of the Immortal Nine level, and such creatures can dominate one side even if they are placed in the main world.

But why are their memories so short?

Is it because they were only made, not raised?

Thinking of this possibility, Cheng Bo felt very frightened, if this was the case, then it would be reasonable for the demon side outside the world to not care about the lives of the demon soldiers, because the demon soldiers were dead, they could still make them.

In order to confirm this idea, Cheng Bo set his sights on several demon generals, and after killing them, his memory was also attracted.

After browsing the memories of these demon generals, Cheng Bo's brows furrowed even deeper.

Because there is no answer in the memory of the demon general.

However, he was almost certain that most of these magic soldiers were created.

There is no past that belongs to them in the memories of these demon generals, they are all promoted from demon soldiers, and the intelligence of demon soldiers is quite low, only the most impossible killing, only by evolving into demon generals, they will have wisdom.

He also got a message from the memory of the demon general, and after each battle, the dead demon soldiers would soon be replenished, maintaining the original number.

"Sister Haile, a million years ago, what was the number of demon soldiers?"

Cheng Bo asked Yun Na.

"More than 300 million?"

"And now?" Cheng Bo asked again.

"It should still be more than 300 million!"

Now, Cheng Bo is 100% sure that the demon soldiers are all manufactured, and in millions of years, there have been countless battles between the gods and the demons outside the sky, and there are hundreds of millions of dead demon soldiers, but why has the number of demon soldiers not decreased, isn't it obvious?

"Sister Haile, do you know where the demon soldiers came from?"

Cheng Bo continued to ask.

Yun Na said: "I heard the captain say that there is a demon transformation pool in the depths of the Outer Heaven Demon Camp, and a certain number of demon soldiers will be born from it every day!"

"Hasn't anyone thought of destroying the Demon Transformation Pool?" Cheng Bo was puzzled.

"Why not!"

Yun Na sighed: "In the past million years, several super gods have died, and they have all dived into the depths of the demons outside the sky to destroy the demon pool, although they succeeded, but soon after, they were able to create a new demon pool. ”

"After losing several super gods one after another, Heavenly Dao also knew that this trick would not work, and no longer sent super gods to destroy the demon pool!"

"Perhaps, the key is not in the Demon Pool!"

Cheng Bo said thoughtfully.

Perhaps only by understanding the origin of the Outer Demons can he completely destroy the Outer Demons.

Time passed slowly, and Cheng Bo felt that the life essence in his body had reached the point where he could not directly absorb it, so he began to urge the "True Dragon Nine Changes" to transform these essences into the power of the imprisoned cow.

An hour later.

The encirclement is getting thicker and thicker, because the demon soldiers are simply fighting more and more, and they can't kill them at all, and there are more and more demon commanders and demon generals watching the battle around.

And after an hour of fighting, the aura of many gods has weakened a lot, and even Yun Na's face has a little more tired.

Suddenly, Cheng Bo grabbed one of Yun Na's hands.

"Stinky boy, what do you want to do, this is on the battlefield!" Yun Na gave him an angry look.

"Huh!"

It was only before her words fell, she let out an exclamation, because Cheng Bo injected a very pure essence into her body, this essence was very easy to refine, and in an instant, it turned into her own divine power, and the tired color on her face disappeared.

But she immediately shook off Cheng Bo's hand and said, "Don't worry, Xiaobao, I can hold on!"

Obviously, Yun Na thought that he was supporting her with his own spirit.

"Sister Haile, I can absorb the demon essence on the battlefield, and the essence I lost to you is all transformed through those demon essences, haven't you noticed that I haven't consumed any of them until now?" Cheng Bo hurriedly explained.

Hearing this, Yun Na really found out about this, and couldn't help but be extremely shocked, there were also gods who tried in vain to refine the essence of the evil demons outside the sky before, but they all ended in failure, even the super gods couldn't do it, and they actually let this kid succeed.

But thinking that the other party is from another world, I am also relieved.

"Captain, Brother Emperor Fall, Sect Elder, you are all close to me!"

Suddenly, Cheng Bo shouted to the other three.

As they approached, he directly transmitted a large stream of life essence through thin air.

Originally, they all refused to accept it, but after listening to Cheng Bo's explanation, they all accepted it.

"Xiaobao, then you will do your best to refine the demonic essence, and the matter of the battle will be left to us!"

Qing Wan said.

Cheng Bo nodded, surrounded by four people in the center to concentrate on refining, and in order to make it easier for him to refining, the four of them also took the initiative to capture those evil demon essences.

At the same time, as soon as they were replenished, they invited other gods to come and receive the replenishment.

With Cheng Bo, the nurse, this group of gods suddenly burst out with unimaginable momentum, and many people who didn't dare to perform overly expensive moves also broke out one after another.

Because of the consumption of dramas, you can come to Cheng Bo here to replenish it immediately.

"Huh!"

After not knowing how much demon essence he had refined, Cheng Bo found that the life rune in his mind had actually undergone a transformation, in short, it was advanced.

With the advancement of the Devouring Rune, the power of Devouring and Refining has increased by more than a hundredfold, and the refining speed has also increased a lot, and a large amount of Demon Essence can be transformed into Life Essence in a breath.

For a while, Cheng Bo simply took his body as the core and formed a network of divine power, connecting all the gods and spirits, and constantly transmitting life essence to them.
