After Tang Zhen returned to the surface, he first contacted the 5 sector Lord brothers.
He had to return to the war tower and recall the reincarnation mirror that was guarding the Supreme tower. At the same time, he had to prepare for the battle that was about to happen.
The reason for summoning the reincarnation mirror was naturally because the soul-gnawing beast was residing in it. Furthermore, it was sleeping in the most hidden corner and would not come out easily.
However, this matter was related to her, so it was impossible for the soul-gnawing beast not to figure it out.
He was familiar with the 5 sector Lord brothers "nature and knew that they were suitable to cause trouble behind enemy lines. Hence, Tang Zhen wasn't prepared to bring them back. Instead, he wanted to keep them to continue causing trouble for the terobo people.
