But this Thunder Punishment Tower is actually 600 meters high, three times as high as the Long Sword Tower.

The same is true for durability. At the ninth level of Qi training in the Long Sword Tower, the durability is 1.9 million.

But the Thunder Punishment Tower's strength at the first level of the mortal realm has a durability of 300,000.

Judging from the realms of several divine guard towers, Gu Changsheng found that every time their realms increased by one level, their durability would increase by the same level as the first level of the mortal realm.

Based on this calculation, when the Thunder Punishment Tower is at the ninth level of Qi training, its durability must be 5.7 million.

Gu Changsheng's guess was correct.

When he spent 205,860 cultivation points to upgrade the Thunder Punishment Tower to the ninth level of Qi training, its durability indeed became 5.7 million.

With such high durability, even Sun Wukong couldn't kill this guy for a while.

This allowed Gu Changsheng to finally figure out a problem.

If it is only ordinary, even if it is enhanced to a high level, it will not be able to compete with real high-level items in terms of qualifications.

Just like the Demon Ant Tower has been strengthened to the Xuan level, but ten Xuan level demon ants cannot defeat a Huangquan sect disciple of the same level!
