The battle in the water made everyone understand why Lu Shu wanted to flood the entire area and why Lu Shu was completely unafraid of the water ghosts destroying the outer city.
That was because he was not only a master of swordplay, but also had the skill of controlling water of the Master Realm. There was originally very few masters in the world and none of them had the skill of controlling water.
Not only was there no such masters in the Luniverse, there were none of them on Earth too!
Therefore, Lu Shu had turned the entire palace into his territory beforehand. It was impossible for ordinary masters to beat him in his territory!
Especially for these types of large-scale battles, the power of the water made it impossible for anyone to go near the palace. Even if they went in, it was difficult for them to exit. Lu Shu's method of closing the water gates and attacking became the nightmare of ordinary soldiers. They had no way out!
