Why doesn't Gray ever smile?

Because he did not see Gray laugh when someone told a joke.

Grey is a front-line counterattack tank that can resist and fight. His powerful damage reduction ability and stable counterattack ability allow him to perform stably in various environments. The higher-level Gray can even kill the opponent in the enemy's turn, which is a presence that makes melee opponents fearful.

The son of the leader of the Shouwang clan, he is also the only one in the clan to survive. A man sleeps alone in a dormant cabin until he is awakened by an ancient voice. Later, in order to hone himself and pursue the truth about the exterminated clan, he followed the other party's guidance and practiced practice all over the world, living in no fixed place until he came to Dengruel Star, met Jin, and became friends with Jin. Only then did he regard Dengruel Star as his new habitat. No matter how far he went to practice in the future, he would return to Dengruel Star from time to time to practice.

The rest

Getting more clues about the Watch Clan and the God of Creation, Gray went to the Bump Competition. He is currently second in the competition standings, and his strength has been recognized by Garderos, who is first in the competition standings.

The Yuanli weapon given by the competition is also Gray's unique Yuanli skill. It looks like a big knife similar to a hatchet, but Gray himself can use it very easily. Coupled with Gray's superb swordsmanship, he is said to be able to cut anything he sees. In addition to the blade itself, Fierce Slash can also strike with sword-like slashes, and can form square pillars for defense or obstruction according to changes.
