Chapter 434 (1/2)

”What? Is there a dungeon here? ” Asked the eagle in surprise.

”Sorry, I forgot it!”

Zhenhong also called: ”yes! The first time we infiltrated, we planned to go underground, but we met the wall of the dungeon, and I forgot it! ”

When she said that, Christina and purple moon beside her remembered. We were all together, but we all forgot!

”What now?” Big pot rice asked.

”What else can I do? Look for the entrance The snow, standing next to the big pot, hit him on the head.

After everyone looked down at the ground, Ah Wei said to himself, ”the ground is covered with ice. How can I find it?”

The underground city of this city is obviously not the kind of aboveboard underground city like Eisinger. There are very large entrances in the underground city of Eisinger, just like the subway station. However, the underground city of this city is built according to the air raid shelter. The entrance is hidden. Even if it is difficult to find the entrance, what should we do when it is completely frozen?

Su Mei suddenly said, ”by the way, how about listening to the echo? You don't have to find the entrance anyway. Just make sure where it's thin and then make a hole through it. ”

”But how do you knock across a meter of ice?”

”Find someone stronger to knock on it.”

Purple moon immediately said, ”my Titan will do.”

”But two are not enough.”

”The sound pressure bomb of the long gun may be able to penetrate the ice.” Xiao Yao proposed.

”No way.” Rose objected: ”the sound pressure bomb of the spear is too small to penetrate. But the sound pressure bomb launched by ziri's birds may be OK. ”

”There are only three! When will such a big city be found? ”

”Yes. Go find sister hammer. ” Suddenly Sumei called out.

”Sister hammer?” We were all confused.

Sumei quickly explained: ”is the last Japanese ninja invasion that the best record of the sister, you also awarded her an angel crystal.”

Everyone together: ”Oh!” The image of MM is so easy to remember.

”That's not enough!” The eagle said, ”why don't we find all the people in the guild who are good at hitting?”

”All right, that's it.”

This damned ice, not only slippery, but also so hard that we can't even penetrate. All the more powerful people in the guild were gathered together and began to look for the weak points in the dungeon. If it wasn't for the ice, I could easily find the entrance with pioneers and rose vines. Now they can't even move. They can't help!

Mm, who got the hammer last time, was quickly asked to help find the weak points. Her big hammer was really easy to use. When she went down, she immediately made an earthquake like sound. White waves have good ears and can tell the thickness of the stratum according to the echo. However, the first hammer went down to detect a 750 meter deep stratum. I really don't know how it was so deep. According to the law, low city should not be dug so deep!

The excavation effect of other guild members is similar. Basically, the depth detected is more than 700 meters, and the depth in some areas can reach more than 800 meters. Is the underground city of this city of special use?

I turned my eternity into a big hammer. I jumped up and smashed it to the ground. With a bang, the ice broke apart with the ground. The frozen earth is as hard as steel, but it is also easy to break.

After more than three hours of knocking, we still can't find the entrance, but we have detected the entrance and location of the dungeon. This damned dungeon is huge, and it's more than 700 meters deep. But now there's a problem. City entrances have been found, and there are several, but there are doors on both sides of these entrances. These entrances were filled with water at the time of the flood. The tunnels closed by the gates on both sides were completely sealed by water. Now, as soon as the temperature drops, the water becomes ice. In other words, the tunnel entrance is completely blocked by ice.

Rose called us together and said, ”we don't have much time. The enemy is still resurrecting. We must move faster. On the one hand, we must stop the counter attack of the blissful city over there. On the other hand, it is too dangerous to dig a hole in the ground. I think something else needs to be done. ”

”What about that? Do you give up? ” Asked purple moon.

I'm not used to shaking my head. I mean, in a different way. Christina, didn't you bring eisenegger's big rig with you? How about trying it on? ”

”The giant drilling machine is for mining iron ore. the drill bit can deal with ice and rock, but that guy is not small,” thought Kristina

”We have air force. Are we afraid we can't deliver it?”

”Then try it.”

In an hour, the parts of five giant drilling rigs were transported to liberty city. The parts that had just been unloaded were assigned to be placed in five thin layers, and with the help of my dragon and other people's giant pets in the guild, the huge parts were assembled.When the rig was loaded, the black bear circled the thing several times. ”This Is this really a drilling machine? ”

”Of course.”

”It's so great, such a perfect equipment, it's really shocking!” He looked at his shovel and said, ”it's better to have modern equipment.”

The base of the giant drilling machine is a hexagonal metal ring with a side length of 7 meters. We specially make it very heavy. The purpose is to ensure that the body of the drilling machine will not rotate with the bit when it is working. The base is fixed on the ground by six steel columns with a diameter of half a meter to further ensure its stability. In order to ensure that the base is level with the ground, it is easy to break the drill pipe if it is uneven.

Above the base, a huge host with a diameter of 7 meters and a height of 12 meters is erected on the base. The dark color and the mechanical structure give people a sense of strength. There is a huge drill bit with a diameter of more than two meters under the drilling rig. The three-way three head dog tooth drill bit is equipped with a magic strengthened diamond blade, which absolutely cuts iron like mud. Behind the drill is a drill driver with a diameter of 1.5 meters. This is a hollow steel pipe with a wall thickness of 35cm.

The fully assembled machine is like a magic tower, with a giant creature beside each rig to help replace the drill pipe. The rig we're on is operated by Kristina, and plague and luck are responsible for changing the drill pipe. After confirming that everything was ready, I nodded to indicate that I could connect the power. Christina put a crystal the size of a watermelon into the power extractor of the machine.

After seeing this, the black bear was startled: ”how much does such a big magic stone cost?”

”I haven't calculated it. I don't think it's cheap. But don't worry. It can take a long time. The average cost is not very high. ”

Black bear depressed way: ”I this kind of poor person or old honest practical shovel bar!”

”Ha ha, you get the price, you get the goods.” As I spoke, I gave Kristina a start.

Christina pressed on the console a few times, then put her hand up and started, pulling down violently. ”Chi! I'm sorry... ” It seems that we have to cover our ears with the harsh sound of scraping glass. The people who listen to this sound are very uncomfortable and feel like vomiting.

The giant drill bit began to rotate slowly, and Christina pulled another lever. The bit speed obviously began to speed up, and the noise became more and more loud, but the harsh sound was gone. Now there was only the powerful mechanical sound.

The high-speed rotating drill bit makes a sharp whistle like sound in the air, obviously reaching the speed. Christina pulled down another lever again, and there was a boom above the machine, and the drill bit began to move slowly down. Suddenly there was a sharp crash, and we felt a tremor at the bottom of our feet, and short-sighted water splashed in the gap between the bottom of the rig and the machine above. The drill bit broke the ice into ice and turned into water as soon as it touched the hot machine. But the air was still cold, and the water immediately turned into ice. We were all scurrying around us, but Christina, standing on the platform, was doing nothing.

The ice and snow suddenly disappeared, then began to fly mud, and then returned to normal. The ground is still shaking, but the harsh sound is no longer heard, only the roar of drilling rig is left on the ground. Christina jumped down and yelled, ”well, from now on, just keep changing the drill driver, and the machine will drill down automatically. The ice on the surface is hard, and it gets faster when it goes down to the soil. I think it's almost through in 30 minutes

I also called out to answer her: ”then as soon as possible.”
