Chapter 407: Building the outer wall, monster mutation

Time passed by slowly, and it was already midnight.

Tang Zhen didn't return to the main tower to rest. Instead, he brewed a pot of hot tea and was drinking it by himself.

On top of the city wall, there were rooms that Tang Zhen had modified. They could be used to store supplies and also provide a place for the soldiers to rest.

Tang Zhen drank the hot tea in his cup as he sat in the spacious stone house. After which, he glanced at the time.

Midnight had passed and the cool down time was over. Tang Zhen once again activated the terrain transformation plug-in.

Under the control of his mind, a loud rumbling sound was heard from the snow-covered land. Then, a huge city wall was lifted from the ground.

The speed of the wall's rise was extremely fast. In the blink of an eye, it had already risen to about fifty meters.

After reaching this height, Tang Zhen stopped rising.

This height was very suitable for both defense and counterattack!
