Tang Zhen's suspended heart relaxed after knowing the specific attribute of the tower's cornerstone.
Although the tempered foundation stone could be replaced if he wasn't satisfied, Tang Zhen didn't have many top quality foundation stones. If this foundation stone couldn't satisfy him, then he would have to search for a suitable foundation stone, which would greatly delay his advancement to the world Overlord realm.
However, he only had a year to recuperate, and then he would have to accept the mission of the fifth battle area. If there was a delay because of the foundation stone, it would definitely not be worth it.
The official missions of the fifth battle area were not as simple as trial missions. They had invaded high-resource planes, which were definitely dangerous.
If he didn't have the cultivation of a sector Lord or above, Tang Zhen would undoubtedly be at a disadvantage in battle.
