I'm The Boss In The Little Demon World! (1)

In the second class of the Essence Opening realm, one's lifespan would increase again, reaching 3,600 years.

In the third class, the increase continues to reach 5,400 years.

…

In the ninth class of the Essence Opening realm, one could live for 16,200 years!

The transformation Su Jingxing's physical body had undergone when he sanctified it had been significant. He had directly stepped into the second class of the Essence Opening realm.

Then, he absorbed the energy from the Mighty Strength Cards and Strength Pills to push his realm to a bottleneck.

That was the limit of the second class of the Essence Opening realm.

After consuming nine Demon Soul Fruits, he broke through his limits and entered the third class of the Essence Opening realm.

This meant that so long as he remained healthy and safe, he could live for 5,400 years.

Having a long lifespan was one of the specialties of a spiritual martial artist.
