According to No. 0's guess based on the murals on the stone walls, the stone door on the first floor of the ruins actually also had a map of the next level carved on it, but it was physically destroyed by Amadeus before it could be translated.

Of course, in addition to the map on the lower level, Zero also received a second piece of information engraved in the common language of the contractors: Neyt gave the apostle the power of resurrection to guard the other side of the underworld, and everything was silent under the silence!

Amadeus ignored Sergeant Allen's resentful look, looked at the stone door more than ten meters high in front of him, and felt a little troubled, and he was still mumbling something.

If he wanted to destroy such a huge stone gate through physical means, the cracks in the nearby walls would probably cause the entire area to collapse. By then, no one from the Alliance Army would be able to escape.

Number Zero listened to Amadeus's murmurings with disdain on his face, then slowly came to the side of the stone door and called Noah to point at a slightly raised symbol text to get her ready, and asked the clerk to immediately

Ti stood in the middle of the door and asked him to press his hand on a raised stone with the Eye of Horus pattern. Zero himself came to the other side of the stone door in front of a raised stone slab that was also engraved with mysterious symbols.

During Noah's countdown, the three of them pressed the stone slab in almost at the same time. In an instant, the entire circular square area made a loud "rumbling" sound, as if there were the sounds of countless mechanisms opening, and even their ceilings were filled with sounds.

A large amount of sand fell down, and some ancient equipment inside the ancient ruins seemed to have been restarted!

The huge stone door blocking everyone began to slowly rise. The heavy friction between the stones made everyone's brains hurt. When they saw the thickness of the stone door clearly, everyone took a breath again.

The stone gate, which is four meters thick, completely hides the entrance to a corridor that gradually extends downward. If the stone gate is opened by irregular means, the entire area will probably collapse. This stone gate is probably still standing in place, motionless.

Inside the corridor is a square space about three meters high, which looks very wide. The topography of the corridor gradually extends underground, and even the most powerful searchlight cannot illuminate the bottom.

Sergeant Allen checked the gas masks again and was about to take someone into it to inspect one. Suddenly, a louder sound came from the dark corridor. The soldiers who had been prepared immediately pointed their weapons at the corridor.

, everyone was shocked when they saw the creatures appearing in front of them. The source of those sounds turned out to be countless bats!

Ordinary bats are naturally nothing to be afraid of and may even be a delicacy in the mouths of Guangdong gourmets, but if those bats grow to the height of a person and spread their wings nearly three meters, then it is a different matter.

These bats, which can make piercing screams, flap their wings and spurt out of the tunnel, rushing towards the Union Army camp. Their huge mouths are open and their canine teeth are intertwined, and their huge ears are stretched high above their heads!

"Flame thrower! Free attack!" Following Sergeant Allen's order, a barrier of flames instantly rose in the corridor in front of everyone. The soldiers who had already prepared the protective work without leakage even built it outside the stone gate.

There were several simple sentry towers, and the area near the corridor was completely covered by flames. The blazing heat burned the hair of the fire-breathing soldiers in the front row until it began to curl.

When all the fuel in the flamethrowers was exhausted, the sound of continuous shooting had already sounded outside the stone gate. Although these huge bats looked terrifying, their strength was very average.

As long as a few accurate shots hit the body or head, they can be killed. Although the weapons in the hands of the soldiers are powerful, the number of bats flying out of the corridor is even greater, and casualties soon appear among the coalition forces.

The bite force of the giant bats is not very strong and can only cause some small wounds on the soldiers' bodies, but when their number reaches a certain scale, it will be a different scene.

When a swarm of bats pounced on a soldier and chewed the unlucky man into a pile of bones in less than thirty seconds, everyone who saw this scene had chills running down their spines.

Zero and Noah quickly retreated and hid next to Sergeant Allen as soon as there was a sound in the corridor. When they saw a large group of giant bats appearing, a trace of smile appeared on their faces.

The difficulty mode of your main quest needs to be completed here!

Before entering the second floor of the ruins, No. 0 found thirty gems from the material storage warehouse and found them in the excavation site outside the ruins, and easily completed the easy difficulty task.

The location indicated by the golden bat in the task bar was right under their feet, but the position kept changing. Since then, he had been paying attention to the news about the golden bat, but he did not expect to find the bat group on the second underground floor.

It seems that the leader of these giant bats is his mission target!

Following Zero's greeting, Noah and a few veterans behind him took out some devices from the backpacks they carried and quickly assembled them. The remaining veterans defended themselves around to prevent them from being attacked.

Not long after, something that looked like a large speaker appeared in front of Zero. When the equipment was started, the very orderly giant bats in the sky suddenly changed into what they looked like after being drunk. They all lost their direction and felt like they were flying around.

It even hit the wall with a "snap". Sergeant Allen looked at Zero in surprise and didn't know what to say.

"That is a high-power ultrasonic generator. Mr. Bruce was worried about similar creatures appearing under the ruins in the desert town before, so he specially applied for it from me. If I hadn't seen it here today, I would have almost forgotten it." Records Officer Ma

Di was on the sidelines and explained to Zero in a timely manner.

Sergeant Allen nodded towards Zero and turned around to start commanding the troops to clear out the bat groups that no longer posed a threat. Since there was no grass growing on Sergeant Allen's head, that part was one of the key targets for the photophobic bats.

After this battle, his shiny head was covered with scratches but nothing serious. To put it simply, the damage was not high and it was extremely insulting!

As more and more ultrasonic generators were assembled one by one, the bat swarm no longer posed a threat to the coalition forces. Most of the bats were shot into sieves by the angry Sergeant Allen, and only a few giant bats escaped along the corridor.

Returned to the lower level.

When everyone finally cleaned up the bat group, they discovered that the corridor seemed to be endless and extended downwards, and the bottom could not be seen. Sergeant Allen took a fluorescent stick, shook it, lit it, and threw it into the corridor that extended downwards.
Chapter completed!
