God-level upgrade system infinite evolution from mosquitoes

The soft sunlight shone into his eyes. Su Cheng faced the light and found himself in a busy city.

"Why are these people's clothes the same as in ancient times? Are they acting?" Su Cheng was puzzled and then noticed his body.

"What's going on???"

Su Cheng was shocked. He turned into a mosquito, and one of his wings was broken.

He didn't do anything bad, he just took a nap, but why did he wake up like a mosquito? God was playing tricks on him.

"Ding, congratulations to the host for activating the god-level upgrade system. In view of meeting the host for the first time, the host will be rewarded with upgrade points: +1."

"Ding, it's detected that the host's wings are broken. Repair requires upgrade points: -1"

"repair!"

Su Cheng's eyes lit up, he looked at his new wings, tried to flap them a few times, and they actually flew.

Looking at the bustling city with people coming and going, Su Cheng felt inexplicably hungry, as if those people were delicious food. Finally, he flew onto one person and inserted his mouthparts into the other person's skin.

"Ding, the host sucks blood, upgrade points: +1"

Wow, this system is so awesome. You can get upgrade points just by sucking blood. Su Cheng was shocked.

"Ding, the host meets the evolution requirements, please choose the evolution part!"

Suddenly, the system prompt sounded again.

"Evolve mouth!" Su Cheng said excitedly.

Accompanied by bursts of pain, Su Cheng's mouthparts became thinner, as if they didn't exist, and were several times harder than before.

"Ding, the host has evolved. Congratulations to the host for getting the Shadowless Mouth. (The other party doesn't feel anything when sucking blood)"

Su Cheng inserted his mouthpart into the opponent's skin again, this time without any obstruction, and went straight in.

"Ding, the host sucks blood, upgrade points: +1"

"Ding, the host has reached two upgrade points and meets the upgrade conditions. Do you want to upgrade?"

"Upgrade!" Su Cheng said with high spirits. With this system, why not worry about not being able to reach the top.

"Crack!"

A pair of big hands suddenly clapped down. Su Cheng felt dizzy and vaguely heard human voices.

"What the fuck, a mosquito sucked so much blood from me?"

A "-1" floated in front of Su Cheng's eyes, and then his body recovered as before, and he quickly escaped from the man's hand.

"Hey, this mosquito is not dead?" Li Qi said in surprise, slapping his hands towards Su Cheng.

"Your uncle!" Su Cheng's face turned dark. Did he hate mosquitoes so much? He quickly flew up into the sky.

Now that he was finally free of the other party, Su Cheng breathed a sigh of relief and looked at the system panel with some distress.

Host: Su Cheng

Race: Mosquito

Level:0

Upgrade points: 1

Evolutionary Talent: Shadowless Mouth

If it weren't for that Li Qi, he would have been upgraded long ago, Su Cheng thought angrily.

"Forget it, don't argue with him!"

When Su Cheng stared at the other person and inserted his mouthpart into the other person's skin, the system beep sounded again.

"Ding, the host meets the upgrade conditions, do you want to upgrade?"

"upgrade!"

After a burst of warm current, Su Cheng felt that his body had become much stronger. The strength in his whole body had greatly increased, and he was able to fight at least three mosquitoes alone.

"Continue!" Su Cheng continued to suck blood, and after a few minutes he reached level three, but he had no intention of evolving.

"System, what are the conditions for evolution?" Su Cheng asked doubtfully.

"Host, you need to suck new things to evolve. The same thing can only evolve once, and the level of the thing you suck cannot be lower than yours."

Su Cheng suddenly remembered that mosquitoes not only suck blood, but also juice, nectar, etc. How could he, a human on earth, even forget this?

Su Cheng flew away from the crowd, found a water source, and stuck his mouthpart into it.

"Ding, the host meets the evolution requirements, please choose the evolution part!"

"Evolve wings!" Su Cheng said happily.
