The reason why Tang Zhen felt a sense of familiarity toward these ruins was because of a memory in his mind that did not belong to him.
When he was building the mage's defensive tower, Tang Zhen received the memory from the city, which contained all the experiences before the destruction of the city.
The world in his memory was extremely similar to the place Tang Zhen was in.
It was impossible to determine that this was the world in his memory just based on the similarity. However, when Tang Zhen saw the black ruins of the building under his feet, there were no more doubts in his heart.
Without a doubt, this was the wizard World in the memory of the wizard defense tower!
He didn't expect that he would come to this place by chance.
Tang Zhen still had a fresh memory of the evil spirits and creatures that destroyed this world. That earth-shattering destruction scene simply caused one's mind to collapse.
