Partial Mastery, Divine Power

Soon, Zhou Chen brought John to his residence and suddenly knocked him out.

Then, he took some blood from John and recorded it in the bizarre book. He took out the bizarre coffin from his inventory and stuffed him in.

Zhou Chen's so-called gift of strength referred to this thing. He did not have a way to rapidly increase people's strength, but the bizarre coffin could.

Although doing so would consume precious lifespan, it was not his loss. Moreover, he had already made the price clear. If John accepted it, he could do so.

As for obtaining blood and putting it in the bizarre book, it was a form of insurance. If John became arrogant after obtaining strength and became disobedient, Zhou Chen would not need to waste time to find him and teach him a lesson. As long as he activated the bizarre book, John would be forced to be obedient.

Of course, this was only to prevent any accidents. According to Zhou Chen's guess, John would not betray him so quickly.
