Eagle Sauce Country's Infighting, Fusion with a Foundation Establishment Demon Core

Generally speaking, the spells cultivators cast almost never harmed them.

Chen Feng had once practiced the Fireball Technique himself. Every time he cast it, the fireball would form in his palm, because the source of its power was his own Spiritual Qi.

As long as it was one's own Spiritual Qi, it was almost impossible for it to cause self-inflicted harm.

But now, this soldier had been burned out of existence by his own Fireball Technique. Chen Feng had never seen anything like it.

Could it be that the Spiritual Qi in the Artificial Spirit Aperture wasn't cultivated by the user, so this happened? Chen Feng wondered.

If that really was the case, the Artificial Spirit Aperture had a major drawback.

Being unable to cast spells was a fundamental difference between its users and immortal cultivators.

"No matter what, being able to improve the body is helpful. I'll let Tiya and the others study it slowly later."

Although the Artificial Spirit Aperture couldn't let ordinary people cast spells, as long as Spiritual Qi could continuously nourish their bodies, it could improve their constitutions and extend their lifespans. That alone was enough.

Chen Feng then looked at the waiting Qiefusi and said, "There was a little accident during the experiment just now."

Qiefusi had still been wondering why the soldier had suddenly vanished. Only after hearing Chen Feng did he understand, and he hurriedly said:

"Master, it's perfectly normal for experiments to fail. As a soldier of Eagle Sauce Country, it was his honor to give his life for the experiment."

Qiefusi felt no sorrow whatsoever over the soldier's death.

Never mind one soldier dying; even if a hundred died, he wouldn't think anything of it.

It wasn't just Qiefusi. The nine soldiers beside him who had completed their evolution didn't
