The explosion began to erupt wildly in the underground space, its huge power fiercely hitting the fragile cave wall, sweeping across like a crazy hurricane! Its power even penetrated the soil and spread to the surroundings.

The underground of the Minsk Cathedral was already riddled with holes, not to mention the naturally generated cracks and caves underneath. The explosion immediately destroyed the fragile balance, setting off a series of chain reactions like a domino effect.

A building next to the Minsk Cathedral suddenly tilted and collapsed strangely towards the west. A lot of dust and smoke came out from the ground, and this was just the beginning! The surrounding buildings also began to collapse and tilt one after another. Even the ice and snow blockade was affected. At least a hundred meters of the place had obvious collapse.

This chain collapse reaction lasted for five or six minutes, as if a small-scale earthquake had occurred. The affected area was concentrated within ten square kilometers with the Minsk Cathedral as the core. Of course, the Minsk Cathedral was the most severely damaged place, with six sinkholes. Not only did several affiliated buildings collapse due to the sinkholes, even one of the main buildings, the confessional, collapsed completely. The hundreds of years old monument was completely destroyed!

When the big explosion happened, Du Yuqi heard the clown's voice by accident, so he completely lost control and left the group to chase after him. Unexpectedly, this gave him more buffer time, so he was able to stay away from the core area of ​​the explosion. When he felt the horror of the magic trap behind him, he had more time to buffer and find cover.

Therefore, when the explosion occurred, Du Yuqi had actually pulled a distance from the center of the explosion, and turned the corner to hide behind a sarcophagus. At the same time, he squatted on the ground next to him, holding his head with his hands. This looked very embarrassing, but it was the ultimate protection for himself! If he had just lay on the ground, he might have been killed by the shock wave from the ground!

After the big explosion, Du Yuqi immediately felt a buzzing in his ears and completely lost his hearing. The whole person seemed to be constantly rolling and colliding, and he felt severe pain in his body from time to time. For a long time afterwards, he completely lost consciousness. This loss of consciousness was not the same as coma - coma means that you don't know anything at all, while this kind of loss of consciousness means that the whole person has completely lost the perception of the outside world, can't see, hear, speak, and the whole body has no feeling, but the brain seems to be still awake, as if although consciousness exists, it is floating on a vast gray ocean!

It was unknown how long it took before Du Yuqi slowly regained consciousness. He then began to cough and retch violently because his mouth and nostrils were full of mud and sand. If one considers the tomb environment he had been in before, the composition of the mud and sand would probably make one feel even more nauseous.

After a long while, Du Yuqi finally calmed down with heavy breathing, but his teeth could still make the crunching sound of sand. Fortunately, he came prepared this time. He took out a bottle of water from the dimensional ring, gulped a few times and then spit it out, only to find that there was still a lot of sand in the mouthwash, and of course blood.

After dealing with these things, Du Yuqi found that half of his face was covered with dried blood scabs, and blood was flowing out of his two ear holes. He felt a sharp pain every time he moved his head. There was a large and obvious hematoma on the back of his head, and it was broken. It was extremely painful when touched lightly.

Next, he looked around his surroundings and realized that he seemed to be trapped in a tomb chamber. Most of the tomb chamber was buried by the sliding soil and gravel, and it seemed to be tilted. When he stood up, he felt it was not stable, and he felt dizzy and wanted to vomit.

"Well, I have a third-degree scalp hematoma, a five-centimeter scalp laceration with avulsion, and a linear fracture of the skull. I might also have a cerebral contusion..." Du Yuqi made a diagnosis for himself with a wry smile, then searched in the dimensional ring, took out a golden communion and ate it. He immediately felt a faint light enveloping him, and his body recovered at a miraculous speed.

However, Du Yuqi also discovered the disadvantage of this thing, which is that it is difficult to use in battle. The enemy must be stupid to let you eat slowly to recover during the battle. Fortunately for Du Yuqi, as long as the medicine is effective, it will be fine.

After he fully recovered, he also roughly understood the current environment, and he felt a sense of urgency. He began to rush to find a way out, because this was an enclosed and narrow space anyway, which meant that if he stayed in it for a long time, the oxygen would be limited. According to Du Yuqi's professional judgment, it could only support his breathing for two or three hours at most - that is to say, if he couldn't find a way out after two or three hours, then he would have to think about how to write a suicide note.

Du Yuqi searched inside the dimensional ring. Although he had imagined various situations before and prepared a lot of materials in a targeted manner, to be honest, he had not considered the embarrassing situation of being trapped by a landslide. In desperation, he still felt that Kulan's Flame Shadow Sword was the most suitable sword for digging the soil. His life was about to be lost, so what was the use of holding the artifact in his hand?

So, Du Yuqi had no choice but to swing the giant sword and dig the soil. Fortunately, his current strength had increased dramatically, otherwise he would not have been able to do such hard work.

An hour passed, and Du Yuqi had already dug more than 30 meters forward, but there were still endless stones and other things in front of him, which really made people feel more and more desperate. Seeing that this small space was getting more and more stuffy, Du Yuqi was very anxious. Although his arms were extremely sore, he still gritted his teeth and persisted. Fortunately, after digging another three or four meters, he suddenly found that the sand and stones in front of him fell down by themselves, and then collapsed again with a loud bang, and a fresh air rushed in from the collapsed hole in front.

One can imagine how Du Yuqi felt when he saw the daylight again. It was as if he had been released from prison after spending more than ten years in prison. However, after he crawled out covered in dust and dirt and the excitement wore off, he suddenly felt that the air inside might not smell so good, as it had an extremely strong stench.

Not only that, it was pitch black all around, and seemingly very quiet, but in fact, if you listened carefully for a while, you could hear a strange rustling sound like spring silkworms eating leaves, and there seemed to be a sad cry!

"Damn, where am I? The underworld?" Du Yuqi muttered to himself, then took out the night vision goggles from the dimensional ring and put them on again. If he didn't need them now, when would he? This was the time for them to work.

When the dark green effect of the night vision goggles spread across Du Yuqi's field of vision, he had a general understanding of the surrounding environment. It still looked like a tomb. On both sides of the long passage were densely packed tombs and coffins. The source of the stench in the air was also easily found, which was naturally the corpse in the coffin.

Fortunately, as a medical student, dealing with corpses is a common thing. After Du Yuqi turned over a few coffins, he immediately stroked the dimensional ring on his finger and frowned:

"The coffin that holds the body looks pretty good, which means the deceased's family was relatively well off..."

"The clothes and attire on the corpse are consistent with the style of Shatli, which proves that this place is still within the scope of Shatli."

"The bodies in the coffins are still relatively intact. Even though the climate here is cold, it's at most similar to the environment in a freezer, which means the date of death is no more than three to five years."

"I just examined a total of eight bodies. Judging from the degree of tooth wear, the youngest one should be around fifty years old..."

"From these clues, we can infer that the common point of these deceased people is that they all died within five years. If we can borrow money to buy the prepared coffins, we can see from the fact that all eight bodies are old that their families should have had good overall conditions when they were alive, with adequate nutrition and relatively good medical resources. Therefore, they all died of illness after their body functions began to decline..."

"Then, I am not at the entrance of the first floor of the tomb. I should be at the bottom of the tomb! These dead people were able to buy cemeteries under the Minsk Cathedral because of their good family backgrounds. They died in recent years, so they can only be buried in the newly excavated third floor cemetery."

When the conclusion of this reasoning came out, Du Yuqi himself felt that it was really incredible, but after careful consideration, he felt that it was the only answer! Du Yuqi was completely unaware of the series of crustal subsidence effects that occurred after the explosion, otherwise, he would have easily accepted this result.

However, at this moment Du Yuqi seemed to remember something. He looked up and took a deep breath. He saw that there was an amazing crack in the dome above, like a cliff hundreds of meters long. At the top of the dome, there were several collapsed white marble statues. The broken but still exquisite tomb niches were the decorations in the "model room" they had visited before.

"...I see. The previous explosion probably triggered a geological disaster, causing a large number of landslides and collapses. The section of the tomb passage where I was staying was too close to the explosion site, so a long section collapsed and fell directly into the third level of the tomb! The drop is at least five or six hundred meters!"

Du Yuqi quickly found out the truth of the matter, and he immediately discovered something crucial:

"Wait!!! According to the information from the Holy Temple, the sealed door opened by the enemy is on the third floor of the tomb. Doesn't that mean it's very close to me?"

"What? I should go and complete the mission now?! Are you kidding me! The enemy set up such a dangerous and huge trap as soon as they arrived. You can imagine how strong they are. Such an enemy must have perfect protection for the sealed door. If I go to destroy the sealed door alone, I will be committing suicide! The most important thing is to get away from it as soon as possible."

Then, Du Yuqi took a look at the steep crack caused by the collapse and could only shake his head in disappointment. Not only was it very steep, but there were also aftermath of collapses from time to time, and large amounts of rocks fell down. It was simply an impossible task to climb the crack with his bare hands, and he could only find another way out.

After sighing in disappointment, Du Yuqi identified the direction and re-entered the undamaged tomb passage on the third floor and began to explore the way up. He had night vision goggles on his head at this time, so it was not difficult for him to walk in this dark, eerie and terrifying tomb passage.

After Du Yuqi walked out about thirty or forty meters, he stopped for a while, then came to the wall next to him and seemed to be groping for something, then walked another thirty or forty meters and repeated the same action. After a while, it was discovered that what he was holding in his hands were two mineral lamps used for lighting here.

As mentioned before, although this mineral lamp has fundamental defects and affects the health of normal people, it undoubtedly has many advantages. There are a lot of them that can be listed casually. The three most striking points are that it is cheap, simple in structure, and durable.

The simple structure means it is easier to repair, and its service life is an exaggerated ten or even dozens of years.

Therefore, the extinction of one mineral lamp was accidental, and the extinction of two mineral lamps was coincidental. However, when Du Yuqi walked here, he actually found that all three mineral lamps were not lit, so this was inevitable.

"Did the people behind the scenes even consider this? Make all the light sources in the cemetery disappear completely..." Du Yuqi pondered:

"The person who can do this must be someone who comes to this catacombs frequently. There are at least thousands of mineral lamps in the catacombs. Tampering with all the mineral lamps... This amount of work is definitely not something that one person can complete in a short period of time. The Minsk Cathedral has been infiltrated more severely than I thought!"

"In addition, the enemy may even set a very vicious trap for this. If I don't have night vision goggles, then after groping in the dark for a long time, I suddenly find a lit mineral lamp in front of me. Then I will subconsciously stay near the light source. Haha, this stay is as stupid as a moth flying into a flame, and the enemy can set a trap for me."
