God-level upgrade system infinite evolution from mosquitoes

Su Cheng's mouth was dry, the demon king's power was terrifying beyond his imagination.

The war was about to break out, and countless demon beasts launched an siege. The human race insisted that they had not captured the other side's son. The demon king desperately ordered all the demon races to attack the city.

For a moment, flesh and blood flew everywhere, and roars resounded throughout the world.

"There are only two days left!"

Su Cheng flew behind the city wall. If his strength increased, there would be no doubt that he would commit suicide. It would be better to secretly increase his strength.

"Ding, the host sucks Xuanwu realm blood, upgrade points: +100"

"Ding, the host sucks Xuanwu realm blood, upgrade points: +100

…………

He lay on top of a wounded man, completely ignoring that the man was seriously injured and unconscious, and inserted his mouthpart into the man's aorta.

Tens of breaths later, Su Cheng flew to another person. Each person only sucked a little blood. He still had this bottom line.

An hour later, Su Cheng rose to the third level of the Yellow Level, and the battle became intense. The Demon King frequently attacked, fighting a man at a high altitude until the void collapsed.

When night fell and the war came to an end, Su Cheng looked at the tens of thousands of upgrade points he had saved so hard and cruelly exchanged his skills.

"Ding, congratulations to the host for redeeming the skill: Invisibility (can be invisible for ten seconds, skill cooling time: one minute)"

Su Cheng was overjoyed. He tried using his skills and found that his whole body was transparent. Even when he flew past Mo Di, the person who stopped the Demon King today, the other party didn't notice him.

Su Cheng was completely relieved now and flew directly back, disappearing into the vast night.

When the first ray of sunlight hit the earth, Mo Di suddenly ordered an attack. Countless humans rushed into the demon group with weapons in hand, catching them off guard.

"Snow Demon King, suffer death!"

Mo Di rushed behind the demon group and used the power of the jade ring in his hand to forcefully repel the seven demon generals and blast into the demon king's location.

In an instant, huge mudslides rose into the sky, dust replaced the clouds, and the sky and the earth became several levels darker.

"Mo Di, you don't keep your promise!!!"

The roar of the demon general sounded instantly, and many human races took the opportunity to rush to kill the demon clan. The tide of demon beasts instantly turned into a sea of ​​blood, dyeing the earth red.

On the other side, Su Cheng also arrived outside Lingyun Pavilion, looking at the strongest force in Lingyun City, and slowly flapped his wings to observe.

His current body size is about the size of a wasp. If someone were to discover him, they would definitely suspect him and even capture him.

"Ding, the host has evolved successfully. Congratulations to the host for gaining the Thousand-foot Eye!"

Su Cheng pulled out his mouthpart from a yellow-level wind spirit bird, and then quickly dodged away while the invisibility technique was still there.

a few minutes later

"Ding, congratulations to the host for getting Tingfeng ears!"

"Ding, the host has evolved successfully. Congratulations to the host for getting Silent Wind Ears!"

Su Cheng quickly used Thousand Foot Eyes and Mi Feng Er to cooperate with each other, and soon learned part of the situation in Lingyun Pavilion. Su Cheng even heard some information about the Little Demon King.

After much thought, Su Cheng evolved the phantom wings and turned them into shadow wings. After being flapped, it was no longer a phantom, but a clone that was the same as the main body. It was just not aggressive, but the speed was the same as the main body.

"Invisibility!"

Su Cheng flew towards Lingyun Pavilion. Once the time for invisibility was up, he stopped. After the cooling time passed, he became invisible again and set off again. In the process, he spent upgrade points to purchase the skill: Penetration.

After spending dozens of minutes, Su Cheng saw the little demon king in the underground stone room. The little demon king had snow-white hair and was as big as a snow pear. At this moment, his body was curled up together with traces of blood.

At the entrance of the stone chamber, there were two men sitting cross-legged in meditation, apparently guarding the Little Demon King.

"If you want to rescue the little demon king, you must face these two!" Su Cheng thought to himself.
