Chapter 870: Entering the Ancient Desolation Tower

"In this situation, has he successfully advanced to the Sovereign-grade?"

"There's no clear explanation!"

After seeing the golden light dissipate, Zhou Han complained speechlessly.

This was because the sky had fallen silent.

The remaining time threads also slowly dissipated and disappeared into the Ancient Desolation Tower.

Without the obstruction of the time threads, he could already easily enter the Ancient Desolation Tower.

All of this was clearly seen by Zhou Han's Origin Eye.

However, he was not in a hurry to enter the Ancient Desolation Tower.

After all, the mission period was a month. It did not matter if it lasted for a while.

What Zhou Han was most concerned about now was the advancement of Eternal Emptiness.

This was because Dao-grade and Sovereign-grade

Those were two completely different concepts.

There was an insurmountable gap.

That was why Zhou Han could not wait to check.
