Feixi's natal essence and blood only have 3,000 'active factors'.

Even if it increased by 50%.

It can barely reach 4,500.

"Yes, it's only 50% at most. Even if you can refine a perfect level of elixir, it can only be improved by 80%!"

Kao knew that Su Chen had extraordinary attainments in alchemy, so he said this.

"Eighty percent...even eighty percent won't work!"

Su Chen's eyes swept around the world's ancient trees.

Suddenly, his eyes lit up and he focused on the saint girl 'Ye Wuyan' of the Purple Demon Clan.

But after Su Chen looked at it for a while.

Just shook his head for a while.

"It's a pity that this purple demon saint only has a soul left, and she doesn't even have a physical body."

Su Chen shook his head and glanced at another light group.

This light group imprisoned none other than Sun Yuan's precious son - Sun Dong!

"Sun Dong's age should not be much older than mine, so I might as well give it a try."

Su Chen murmured in his heart.

Just as he was about to take action, he heard the taunting voice of 'Kao'.

"Don't try to set your sights on him. This guy has been sucked by the ancient tree of the world for so long, and most of the vitality in his blood has long been lost."

Su Chen's mind moved and enveloped Sun Dong.

After scanning around, I found that it was exactly what the 'Kao' said.

Sun Dong's spirit has deteriorated a lot.

"We can't let the World Ancient Tree suck it in anymore, otherwise, I will have to fight for my life later."
