Research showed that when human Evolvers absorbed spirit plant extracts, over 90 percent died outright, while the small remainder suffered severe adverse reactions.
Put simply, if they did not die, they were crippled.
However, those cases all involved using spirit plant extracts as evolution materials—that is, they had absorbed spirit plant extracts one tier above their own level.
As a Saint Tier Overlord who had evolved four times, Feng Buqing should have absorbed a Tier 5 extract as evolution material.
But the Spirit Root Tree extract merely possessed some characteristics of a Tier 5 extract; it had not truly reached Tier 5.
Therefore, Su Ze had no idea whether it could poison Feng Buqing to death.
Most likely, it would merely be like taking the wrong medicine and cause some adverse reactions, but not prove fatal.
Moreover, Feng Buqing had just drunk a huge amount of Tree Marrow. It was a miraculous healing medicine capable of repairing any injury. If anything really went wrong, the Tree Marrow would probably save him anyway.
Su Ze had no other choice. He could only give it a try.
He had already made up his mind that if Feng Buqing truly suffered a severe adverse reaction, he would take the opportunity to slip away.
After Feng Buqing drained every drop of liquid from the tree trunk, he simply stood there stiffly, completely motionless, as though he had been hit by a paralysis spell.
There was still that same foolish, dim-witted look in his eyes that Su Ze found familiar.
No reaction?
Could the toxicity of the spirit plant extract and the healing effects of the Tree Marrow have canceled each other out?
Su Ze worked up the courage to step forward and call out to him, but received no response.
Had he gone stupid...?
