Time passed little by little, and in the blink of an eye Fu San had been unconscious for three days and three nights at the bottom of the sea.

Ding! System reminder: The host must evolve the toxin antibody skill as soon as possible, otherwise his life will be in danger!

The electronic music woke up Fu San's brain a little, and he wanted to open his eyes, but no matter how hard he tried, he couldn't open his turtle eyes.

Fu San was so weak at this moment that he had no choice but to lie quietly on the bottom of the sea, constantly communicating with the system.

"System, how many evolution points do I have left?"

Ding! The host currently has enough evolution points!

"System, help me use all the evolution points to upgrade the skill poison antibody!"

Ding! Congratulations on the evolution of the host skill Toxin Antibody to the top level! It consumes 30,000 evolution points!

Ding! Congratulations on evolving the host skill Toxin Antibody to the second level primary level, which consumes 50,000 evolution points!

…

Ding! Congratulations on the evolution of the host skill Toxin Antibody to the third level of advanced level, which consumes 200,000 evolution points!

Ding! The system reminds that the host’s evolution points have been used up! The virus on the host is under control! Please clear it quickly!

Although the virus is under control, Fu San still has no strength at all.

"Oh! It would be great if I had a bottle of virus serum! Now that the evolution points have been exhausted, what should I do next? Huh? My virus is under control. Is it because my toxin antibody has advanced to the third level of evolution? What if?

If that’s the case, then there’s a way!”

Fu San muttered in his heart for a while. Suddenly, Fu San's eyes locked on the blue blood in the water.

"I can't control that much anymore! Even if I die, I still have to give it a try!"

Immediately, Fu San used all his strength to slowly crawl towards the place where the blue blood was thickest.

Gulu gulu!

Take a few mouthfuls of sea water with blue blood.

Ding! Congratulations to the host for swallowing the blood of the infected person and gaining 100,000 evolution points and 20,000 experience! The effect of fighting virus with poison has been achieved!

"Really? This is great!"

Immediately, Fu San opened his mouth and absorbed the sea water without listening.

Ding! The host's body is deteriorating!

"How could this happen? Did you drink too much sea water with blue blood? No! I have to think of a way!"

Fu San had previously used poison to fight virus, eliminating many viruses and bacteria, and his physical strength had also recovered a lot.

Even if it worsens now, it will be much better than before when the whole body was completely weak.

Fu San hesitated for a moment, and finally he set his sights on the infected person.

"Done!"

Immediately, Fu San quickly crawled to the side of an infected person. Without hesitation, he opened his mouth and took a bite on the infected person's foot.

Hiss!

Fu San took this bite and tore off a large piece of flesh from the infected person.

Ding! Congratulations to the host for swallowing the flesh of the infected! Gained 200,000 evolution points, 50,000 experience, and gained the skill: Upright Walking (Passive)!

Ding! System reminder: All viruses and bacteria on the host have been removed!

Ding! Congratulations on the host level rising to level 9! The attributes have been improved!

"What? Cleared? Leveled up? Can you still get skills? Or walk upright?"

Fu San couldn't believe that all of this was real. If it weren't for the fact that his attributes had changed greatly, he would have thought that the system was deceiving him.

Fu San confirmed that all this was true, and immediately stood up, moved his two hind paws, and started walking slowly.

"Haha! Yes, you still look good walking like this! From now on, I can hold Qianqian's hand and walk in the mountains and forests! Haha..."

After three great joys, he immediately jumped up and landed on the submarine again.

Hey!

With a wave of his sharp claw, he directly ended the life of an infected person.

"Brother, I'm really sorry. You can only harm more people while you are alive! I can only deal with you first!"
Chapter completed!
