God-level upgrade system infinite evolution from mosquitoes

The Shadow Demon Clan actually possesses the Demon Emperor, and things suddenly become difficult. Su Cheng is well aware of the horror of this realm. It can be said that Ling Youruo cannot catch a single move in front of him.

"What to do!"

Su Cheng had no confidence at all. If the Demon Emperor was in charge, he would still be able to think of something, but now that there is a Demon Emperor, he is afraid that if he makes any move, he will be killed by the opponent!

Seeing the boundary barrier getting thinner and thinner, Su Cheng remained motionless.

Finally, a small hole formed in the boundary barrier, and the Demon Emperor breathed a sigh of relief and took back his power.

"Ding, the host task failed, upgrade point: -50000000"

The small hole that melted out began to grow larger, and the aura that was different from the Heavenly Dragon Demon Realm surged out of it, wisps of threads, forcefully opened the small hole, and poured into this world crazily.

The world war is about to begin!

The Demon Emperor stood up and left, calling two high-level Demon Kings to guard him, while he and the other Demon Emperors went back to recover.

"Even if it can't prevent the boundary barrier from being destroyed, it can slow down its expansion!" Su Chengxin said.

After the Demon Emperor and the Demon Emperor disappeared, he took out Ling Youruo. As the War Emperor, Ling Youruo was at the same level as the Demon Emperor. There was almost no fluctuation, and she knocked the opponent unconscious directly.

Su Cheng brought the two demon kings into the Sumeru space and joined forces with Ling Youruo to prevent the boundary barrier from further expanding.

However, it's no use.

The two of them were unable to stop it at all. Once the boundary barrier was opened, the gap kept expanding, and they were unable to interfere with it due to their strength.

"System, is there any solution?" Su Cheng asked.

"Ding, the ancient energy of Youying can repair the boundary barrier. The host has the source of Youying and can repair it, but it will take ten years!"

"So long!" Su Cheng was stunned.

"Ding, host, you must understand that it has taken the Shadow Demon Clan to melt this cave for more than a hundred years. Although Youying's ancient energy can be repaired, it is not that fast. This is because of the source of Youying!"

Su Cheng accepted this reality.

He asked Ling Youruo to enter the Sumeru space and kill the two demon kings. Then he forcibly divided the soul blood into two parts and merged them into the bodies of the two demon kings.

Innate ability: Parasitism!

Su Cheng's face was pale, and his soul sea had shrunk by almost half. The ability to parasitize was too much of a drain on his soul sea and blood essence. Parasitizing two demon kings at the same time was a bit too much for him.

"You Ruo, you are strong, use your cultivation to refine the Nether Fire Source into this cave!" Su Cheng took out the Nether Fire Source and handed it to her.

Ling Youruo immediately activated her power, and Youyingyuan exuded ancient energy, and then frantically covered the boundary barrier and filled up the hole.

"There's a lot left, what should I do with these?" Ling Youruo asked, holding nearly half of the Youyingyuan.

"System, what is the use of Youyingyuan?" Su Cheng asked.

"Ding, currently, for the host, it only has the effect of enhancing the spiritual weapons!"

Su Cheng was a little depressed and said to Ling Youruo: "It can strengthen the spiritual weapon. You can refine it into your spiritual weapon!"

Ling Youruo nodded and put it away. Su Cheng took out the two demon kings. They opened their eyes at the same time and their eyes fell on Su Cheng.

"You can go, although I don't know how long I can last!"

Su Cheng said to himself, if Ling Youruo returned to the Sumeru space, he turned into a mosquito again and flew out.

The two demon kings are guarding here quietly. The ancient spirit of Youying is like a bug, translucent. In the process of repairing the boundary barrier, its body gradually disappears and becomes transparent.

On the other side of the boundary barrier, there seemed to be the sound of steel clashing, frantically bombarding the barrier...
