Fortunately, what Sui Xiong was worried about did not happen. After an intense battle, Yuslar did not manage to break through the defense of the Highest Tower after all. It was blocked about a mile away from the coastline.
This distance, in fact, was very close. For a war on Earth, it could almost be considered as a battle at the level of a face duel. But as a war on this world, a distance of a mile was enough to serve as a buffer for the two sides. There was no need to worry about overly drastic means.
