Chapter 621 Grace Traits: Humanoid Nuclear Weapons_2

Li Zhengfan fell silent, seeming to be waiting for something.

But ultimately, it never came.

Those who, like him, were waiting for some command, did not receive the order they had anticipated, and thus, the experiment truly began.

In fact, he was waiting too, but ultimately, it never came.

Li Yuanba spoke up, using the term "old man" again, leaving people momentarily uncertain as to whom he was addressing.

But this wasn't important, because the two people who could be referred to as "old man" by Li Yuanba, would surely hear him. The difference was, one could hear him immediately, while the other would hear after three minutes.

"I told you before, if I can't do it, you certainly can't either, because I am Li Yuanba."

Hearing this, Ji Xinghe's eyes suddenly lit up with relief; he knew Li Yuanba had come to understand.
