Fang Jie looked at the last two skills, Solid and Self-repair, which are used to maintain oneself.
The Solid skill is truly solid. After experimenting, Fang Jie discovered that this skill requires even a Legendary Level strong person to attack several times to break it, which indicates its hardness.
Even if it isn't used as a means of transportation, it can serve as a shield.
Imagine during an enemy attack, deploying a row of Undead Flying Boats.
This would be equivalent to creating a wall out of thin air, and not just any kind of wall. Although it's a bit more expensive, due to the Undead Splitting ability, this usage is actually much cheaper for Fang Jie than a regular wall.
Specifically, it can be tested later. As for Self-repair, its repair ability is also very strong.
It can be said that as long as it's not shattered all at once, no matter how badly damaged, it can still recover bit by bit.
