Solving the Puzzle

The next day, Han Sen logged into the virtual camp at the time he had agreed with Tang Zhenliu.

According to the ID name that Tang Zhenliu told him, Han Sen added him as a friend. Tang Zhenliu accepted Han Sen's request and invited him to enter the room, changing the setting to "no audience allowed."

Tornado Knife was one of the secrets of Tang Zhenliu's family. Although it was leaked once, the secret still needed to be kept safe.

Tang Zhenliu demonstrated for Han Sen at a slower speed than normal. In addition, he told Han Sen about the keys of the Tornado Knife in slow motion, which could not be seen by outsiders.

Tang Zhenliu's life on the front was different than Han Sen's life away from combat. Because Tang Zhenliu could not make much time every day, he was sacrificing his limited resting time and sparring one hour a day. Therefore, the two did not speak at all and went directly into the fight.
