Uchiha Madara was dug out at the beginning of the tomb robbery

"Mr. Chen is in trouble! The ground is full of water! If the lead wire is exposed to water, it cannot be used!" Mr. Kitano said anxiously.

"Don't worry, nail the rope to the wall, then wrap the lead around the rope to connect the detonator. Put a few more detonators. This time, the passage will be blown down!"

As the leader of Xiling, Chen Niansheng was very proficient in all kinds of tomb demolition methods. He knew that there was not much to worry about at this moment, otherwise all of them would be drowned on this level!

Mr. Kitano immediately set up a rope in the air according to Chen Niansheng's method, and then wrapped the lead around the rope and connected it to the detonator so that it would not get wet.

However, everyone still underestimated the speed of the rising water level. As soon as Mr. Kitano lit the fuse, the water level flooded the bottom detonator and spread towards the second detonator above at a speed visible to the naked eye!

Moreover, the stone cracks above the tomb also began to seep, and then it started to rain, and finally it rained harder and harder!Just when the fuse was about to detonate the second detonator, it was suddenly extinguished by water dripping from above the tomb!

"Oops! The fuse is still out! What should I do now? Or I can just throw a detonator over!"

Mr. Kitano immediately held the detonator and ignited the fuse. Before Chen Niansheng could speak, he had already thrown the detonator!

bang——

There was a loud noise, and a huge shock wave rolled up the water and rushed towards everyone!Gu Xiaoan, who was already in pain all over his body, couldn't bear it anymore, and was instantly lifted several meters away by the water waves!

"Mr. Kitano! Can you not be so reckless? Fortunately, there is water blocking it, otherwise we would all be blown to death by you!"

Gu Xiaoan was very annoyed. Mr. Kitano didn't use his brain at all!Can't you see that such a narrow space cannot be easily blasted!

However, Mr. Kitano didn't care about that at all. He just wanted to blow up a passage as soon as possible, so he was going to detonate the detonator again!

Chen Niansheng grabbed the collar of the other party's clothes and shouted very loudly: "Don't waste it! This is useless! Change the drill bit immediately and drill holes!"

"It's definitely too late to drill holes now!" Mr. Kitano didn't understand why Chen Niansheng asked him to drill holes now.

"Punch holes if you are told! Don't be annoying!" Chen Niansheng continued to yell.

Mr. Kitano didn't dare to ask any more questions and quickly changed to the largest drill bit to drill the hole.

But the drill bit was halfway through when the machine started to smoke!Because the big drill bit is too powerful, the machine cannot sustain it for too long under overload operation!

"Mr. Chen! The drilling rig is broken! What should we do now?" Mr. Kitano asked nervously.

"You missed the mark at the critical moment! You Japanese people are really holding us back!"

Chen Niansheng mumbled and took out several steel pipes from his backpack, then spliced ​​them together, installed a diamond drill bit at the bottom, fixed two special bearings in the middle and top of the steel pipe, and crossed the two steel pipes to fix the middle steel pipe. , in this way, a simple drill gun is completed.

I saw Chen Niansheng pulling out a steel wire from the bearing device in the middle and pulling it back hard. The steel pipe in the middle drove the drill bit to rotate rapidly!The efficiency of this drilling is not much worse than that of a machine drill gun!

As the saying goes, don’t do porcelain work without diamonds. Diamond-made drill bits are very strong and sharp, and are also very effective for this thick bluestone!

The bluestone slab in this passage is double-layered, with a waterproof coating in the middle, so even if it was blasted with a detonator just now, it would not explode easily!

The first layer of bluestone was slightly thinner, about fifteen centimeters. Mr. Kitano had almost drilled through just now, so it didn't take long for Chen Niansheng to drill through the first layer of stone.

However, after the waterproof coating in the middle is attached to the drill bit, the efficiency of drilling is suddenly reduced, making subsequent drilling very difficult!

"Uncle Chen, can't we drill anymore? How about we quickly find the exit?" Gu Xiaoan suggested.

"It's too late, unless we are unlucky! I guess it's because the drill bit was stuck by the waterproof layer under the slate, otherwise the efficiency wouldn't have suddenly become so low!"

Chen Niansheng was sweating profusely from exhaustion. He estimated that he could drill through the second layer of bluestone in about 5 minutes!

"Mr. Chen, let me help you. You need to rest for a while."

Mr. Kitano saw that Chen Niansheng was very tired, so he immediately helped him pull the mechanical device.

At this time, the water level has risen to everyone's waist, and it is estimated that it will not be long before the water reaches the neck!

Since it was difficult to use strength in the water, it took Mr. Kitano more than ten minutes to drill through the second layer of stone!

"Drilled through! Mr. Chen! What should we do now?"

Mr. Kitano didn’t understand the purpose of drilling holes at all, because if they had to rely on such a small hole for drainage, everyone here would drown!

However, at this time, Chen Niansheng took a deep breath and dived into the water, and then used another section of steel pipe to block the hole. This way, the water in this layer stopped flowing downward.

"Mr. Chen, what are you trying to do?" Muto Shizuka also had a look of confusion on her face, not understanding why the other party wanted to block the hard-fought hole again.

Chen Niansheng did not have any explanation at this moment, but stuffed the detonators into the steel pipes. These detonators soon followed the steel pipes and fell into the fifth-floor tomb!

At this time, Chen Niansheng inserted a detonator with a long fuse into the steel pipe and ignited the fuse!

"I understand! You are going to blow up the fifth floor! But will this allow us to escape from the predicament?" Mr. Kitano was somewhat worried, because if the fourth floor did not collapse, they would still die here!

However, at this moment, there was a loud noise, and the entire passage shook violently. However, the floor of the fourth-floor tomb chamber did not collapse immediately, and it still looked very solid!

At this moment, Chen Niansheng said: "Then we will leave it to fate. Let's see whether our fate is better or whether this passage is stronger!"

The tomb becomes stronger as it goes down, and even detonators are not easy to explode.

The reason why Chen Niansheng wanted to open a hole in the ground just now was because he wanted to use the explosive force to have a huge impact on the fourth floor. Moreover, only by blasting from the fifth floor can the safety of everyone be ensured. Otherwise, the blast would be carried out on the fourth floor. If so, they will be killed before the stone slab is exploded!

The power of the pile of detonators just now was quite strong. Although the top slate on the fourth floor was not damaged, it had cracks, and a large piece of the bottom slate fell off!

Therefore, now is the time to resign oneself to fate. Either the passage collapses and everyone is rescued, or everyone drowns in the tomb on the fourth floor!

Not long after, the water level in the tomb had risen to everyone's necks. Muto Shizuka, who couldn't swim, needed Gu Xiaoan's help to drag her body to breathe.

In comparison, the situation of Gu Xiaoan and the others is slightly better, but there is not much breathing space left for them in the entire passage!
