Half an hour later, just as the building had been excavated two floors and the bottom floor was beginning to be revealed, there was a faint roar and fierce fighting in the half-empty tunnel of the underground city.

"You demons, hand them over, or I'll kill you cleanly!" A gruff roar came from far inside the tunnel.

"Hurry up, block the passage!"

The next moment, a violent energy fluctuation came from the cave above, and it felt like the top of my head was shaking.

Ling Li and Yutai Muye glanced at each other, this should be the powerhouses of the Eastern Regions attacking.

Now is a good opportunity, those evil cultivators and demon clans stopped digging operations, and some of them jumped into the air and began to reinforce the defending accomplices in the passage.

Raiding from behind is the most hassle-free.

Ling Li was about to make a move, but saw seven or eight guys in black robes walking out of the ground from the opposite side of the square.

"Humar, you take the people of Eagle Mountain Hall to continue digging, don't worry about the affairs over there." A cold, slightly hoarse voice said.

"Yes, Holy Envoy!" An evil cultivator with a big beard touched his chest with his right hand and bowed in reply.

Some of the people continued to excavate, and the men in black also rose into the air and entered the tunnel.

Ling Li suspected that those missing Eastern Regions cultivators were in the place where these people came out, so he didn't act for the time being.

Before raiding the enemy, he still wanted to rescue those who had been taken away first, otherwise in the battle, these evil cultivators would use these people as hostages or frenzied to inflict harm, and they would regret it.

Thinking of this, he continued to hide his body in the shadows behind the wall, observing the enemy's movements while carefully calculating the rescue plan in his heart......

Standing in the dilapidated building with a dozen floors left, overlooking everything in front of them, although there were ruins everywhere, the excavated building was surrounded by a large square, and there was not much to block their view.

The battle in the tunnel above seemed to be getting more and more intense, and the rumbling and violent shaking sound came from the mountain, and it was faintly mixed with the sound of shouting and scolding.

The battle continued, and it was getting closer, and it seemed that the men of the Eastern Regions had the upper hand.

As the original guards around the square also entered the passage and carried out reinforcements, except for the dozen or so people who were still digging and cleaning up the ruins, there was not even a single sentry below.

Ling Li and Tantai Muye came down from the collapsed high-rise building, circled along the periphery of the square, and with the help of the cover of the ruins, they came to the place where the black-robed people appeared just now on the opposite side of the square.

It is a sturdy, monolithic five-storey building with elevators and emergency walkways going deep underground, as well as several floors underground, somewhat similar to an underground air defense installation.

Access to the underground air defense facility is located on both sides of the lobby on the first floor of the building, and there are stairs and elevators, but the elevators have long been damaged, and there is a large hole in the metal door of the elevator shaft. The traces of the hole are new, and it is likely that the cultists broke them while cleaning them up for insects or other creatures.

There was no one to defend the passage on both sides, Ling Li thought about it, but chose the elevator shaft on the right.

Since the other party is very relieved not to send people to guard, there must be many means of protection and surveillance arranged in the staircase passage.

The two of them walked to the abandoned elevator shaft, radiated their consciousness and examined it, and found that although its structure was somewhat distorted and deformed, it was still well preserved. The depth of its interior is about sixty meters, and it seems to be blocked further down.

"It seems like it can lead down there." Ling Li said.

Tantai Makino said: "I'll go down and have a look first!" With that, he twisted his body, and he had already flown into the elevator shaft and jumped straight down.

Ling Li's heart said that this master of goods is bold, and others can't learn it, otherwise it won't be enough to have ten lives.

Even so, he also followed the same example, and jumped down with Yutai Makino.

Anyway, there is a cushion for him below, and even if he falls, he will smash this guy first.

Yutai Muye is indeed strong, and he didn't open the domain field until he was about to land, and his body suddenly stopped falling, and then landed steadily on the ground. Unlike Ling Li, he let his body float in a high place and slowly descended.

The alloy steel door of the elevator at the exit was already badly deformed, twisted and inlaid between the wall columns of the exit. If you break down the door, you will definitely make a lot of noise.

Makino's gaze fell on the ventilation and access openings of the elevator shaft, "They have arranged small protective formations there. ”

This time, it was Ling Li's turn to show his skills, he approached the access window, put his hand on the wall, and under the prompting of the system, absorbed the energy of several source energy crystals that provided energy for the formation.

Without energy, this formation would be scrapped and would have no effect.

This hand can't even be done by Tantai Makino.

"This ability is very powerful, if there is a chance in the future, I will take you to the treasure house of the Dark Lord or the Blood Demon Old Monster to take a turn......" He also looked at Ling Li with some envy and said.

The two of them got out of the access window and came to the passage of the underground bomb shelter.

"Be vigilant and defend your country!"

Ling Li saw the dark red slogan sprayed on the wall of the elevator, as if he had the illusion of visiting an underground arsenal on the blue star.

There was no one on this level, and Ling Li and Tantai Makino were about to search up the passage, and after passing through the corridor, they saw several scattered human bones in the room. The bones were weathered on the surface, and it seemed that these people were ancient humans who had died in the disaster.

This underground anti-aircraft facility is a tightly reinforced concrete fortress, although in some places it has been severely twisted by the actual crustal changes, revealing thick steel bars, but the whole is basically intact.

There was no light in this lower level, and there were not many traces and breath left after the evil cultivator's activities, and it seemed that they had only checked it slightly, and they did not mean to use it for a long time.

The two of them walked up two floors of stairs in the darkness when they felt a faint light coming in through the corridor outside.

Turning to the corridor, you can see that there is a small source energy lamp embedded in the wall at the corner more than ten meters away, emitting a pale yellow light. The walls of the hallway had large patches to reveal the gray concrete walls, and on the other side of the corner, the light seemed to suddenly become much brighter, and the voices of some people could be heard.

Approaching the corner, Ling Li suddenly smelled the aroma of wine and meat wafting over.

There should be someone!

Coming to the corner, he stopped slightly, first emitted his divine sense, and did not notice anyone, so he quietly poked his head out to look......
