"This energy concentration is at least ten thousand times that of Tiancheng." Gu Shanhai sneaked into it quietly and couldn't help but sigh. Then he explored the situation of the cave and couldn't help but praise: "What an ingenious design."

The Celestial City is used as a large-scale energy gathering and transmission device to ensure the spiritual energy of the cave. Even the heavenly beings in the Celestial City are absorbing their own essence, energy, spirit, etc. as a part of the supplement at all times, from birth and old age to illness and death.

The reason why martial arts is taught to heavenly beings to make them stronger is to extract better spiritual energy.

Don't even worry about security. Even if the heavenly beings find these caves, they can't enter. With their low spiritual energy quality, if they really enter this spiritual energy environment, they will only end up dying violently. There is no possibility of dealing with them.

The martial arts immortals pose a threat.

Mortals are even less looked down upon by the true immortals of martial arts, not to mention that mortals cannot enter the Heavenly Gate and reach the Heavenly City at all, let alone those superficial skills cannot reach the threshold of entry.

Players are not looked down upon by them either. They are just true martial arts immortals, just strangers. They can just survive in the mortal world, but can they go to heaven?

Of course, in order to avoid accidents, there is a Tianmen that isolates the Celestial City from the mortal world, making the last variables disappear. Unless there are necessary things like exterminating Huang Yanshan's family, it is basically just with the imperial court and the Tianzong Demon Sect.

Communicate within a fixed period of time.

However, even this kind of communication is actually done remotely.

Gu Shanhai originally thought that the gods were food, but he didn't expect them to be fuel. The former was eaten at once, but the latter was squeezed and burned all the time, both in life and death.

"You really can't underestimate anyone."

After seeing this method, Gu Shanhai became increasingly vigilant.

I carefully went deep into the cave. The cave was said to be small, but compared to the city of Tiancheng, the actual area was not small at all. It was probably artificially widened.

They were able to stabilize the Celestial City and build such a city. It would not be too difficult to expand the cave.

As he moved forward, Gu Shanhai also entered the core area, a core area blocked by a special martial arts. He could hear the powerful heartbeat and breathing, but no matter which sound it was, it seemed long and soothing.

, obviously due to a special state formed by a certain dormant technique.
