Since both of them relied on the Heaven Tower to advance to a two-digit number, there was no distinction of strength in their spirit grids.
Even though Heng Tian had become a two-digit number in an extremely ancient era, he still hadn't gained any strength enhancement, as his power had been locked away long ago.
For this reason, Heng Tian could not take a significant advantage.
Of course, Wang Ping could not take any advantage either and was even in a relatively weaker position.
After all, even though Heng Tian couldn't increase his strength, he had lived through a long period of time. His control over two-digit level power and his combat experience at that level were not something Wang Ping could compare to.
However, just like this, neither could do anything to the other, and neither could wipe out the other or determine the outcome completely.
Even if one party killed the other once, the other party could still come back to life.
