Zhao Hai let out a long breath and transferred his power of the will into the hall. As soon as his power of the will entered the hall, he immediately understood the purpose of the hall. To put it bluntly, the hall was like a huge magic weapon. He could release it, fly in the sky, attack enemies, and most importantly, he could use it to refine weapons and make drugs.
When Zhao Hai saw this, he was overjoyed. He finally understood that he didn't have to worry about anything anymore. He didn't have to be on thin ice anymore.
In the end, Zhao Hai saw the small tree in the hall. He didn't know if it was an illusion, but he felt that the small tree was growing better than before. The leaves were denser, the color greener, and it looked more energetic.
