The faint laughter was swallowed up in the blizzard, not too far in the howling cold wind, and therefore, not heard by Bruce.

At this time, he was in the guest room on the other side of the manor, changing into his bat suit,

He hadn't gone to the helicopter to get the engine before, not exactly to get angry with Lux, in fact, because Selena could only get some less heavy portable equipment, and a whole set of batsuit and bat gear were left on the helicopter, which Bruce brought together when he went to get the engine again.

Just like Lex, after the three of them separated, they didn't actually do what they had planned, except for Clark who went to the reception room to check on him because he suddenly received a mysterious phone call, and Lex and Bruce had their own extra plans.

Lex's first goal is to go to the bathroom to dispose of Lyonel's body, and he doesn't plan to find the entrance himself, but wants to wait for Bruce and Clark to finish their work and pick up the bargain himself.

Of course, Bruce expected this, so he didn't plan to work for Lex, his plan was to get back to the guest room, change into a full bat outfit, and then make an entrance by his own means.

Although walking through the door is a more civilized way, Batman rarely uses this method, rather than betting on which of the three of them will find the entrance first, or betting on whether they will share it with others after they find it, it is better to do it yourself and have enough food and clothing.

Since the entrance is underground, theoretically speaking, as long as a passage to the underground can be made, then it is equivalent to an entrance, so Batman's plan is to build a bomb and then blow it up directly.

There were no materials to use in the Mayor's Mansion, but Bruce didn't go to get the helicopter engine to compete with Ricks, he was originally trying to use the helicopter engine to create a bomb.

Of course, the engine alone wasn't enough, he had to go to the helicopter and remove some other parts, but fortunately, no one but him could go to the roof of the building next to him, so the helicopters there became his material warehouse.

At this point, he was assembling the slightly larger bomb in the guest room, moving very quickly, trying to make it before the other two found the entrance, and then be the first to go underground.

After working here for a while, Batman finally made a bomb with a slightly rough appearance, but in reality, this thing was very powerful, much stronger than the miniature bomb he brought, enough to blast the ground and open a passage.

He carried the bomb to the balcony, lowered it with a rope, jumped down himself, and carried the bomb to the courtyard in the middle of the manor.

The reason why I didn't go indoors was because I was worried that the power of the explosion would be too strong, which would affect the building structure, and once the manor collapsed, the occupants might be in danger, which was not what Batman wanted.

After the bomb was planted, not long after, a violent explosion sounded, and the ceiling of the entire manor shook violently, falling countless powders and dust.

The directional blasting bomb proved to be very useful, and the basement of the manor was not very deep, and after the explosion, a visible entrance appeared in front of Batman, but it was pitch black and the condition was unknown.

With a "hiss", Batman threw a flare down, and after a short bright light, the scene inside was illuminated, which seemed to be just an abandoned cellar, and Batman frowned, unsure if he had found the right place.

Taking a detector out of his belt again and throwing it down, he watched the changes in the readings on the screen, and after a while, Batman jumped.

Once you go down, it's just like what you see from the outside, it's really just an abandoned cellar of a manor, with a pile of wooden shelves and barrels and whatever, and it doesn't seem to have any secrets.

A door in the corner caught Batman's attention, as he noticed that there was a faint light behind the door, which did not look like the light of an oil lamp or candle used in an English manor, but rather the cold light emitted by a modern lighting system.

Batman walked over, but instead of pushing the door, he stood far away and threw a batrang at the door.

"Hugh! Stop! Stop! Stop! Batman nimbly rolled to the side and reached the corner of the room, dodging the fire from the miniature machine gun on the roof.

When the door is opened, a high-tech corridor appears behind it, with a metal stitched floor, light strips on the walls and ceiling, and two automatic miniature machine guns mounted on the ceiling not far away.

The art style here is completely different from the manor on the ground, Batman is on his guard, he gets stuck in the dead corner of the machine gun fire, throws the batarang at the machine gun, and after a few darts, both miniature machine guns flash electric sparks, and they can no longer be fired.

As Batman walked into the hallway, he threw another flare in front of him, and he found that there seemed to be a central hall-like place in front of him, but the lights were not on, as if the lighting system was broken.

Walking down the hallway, there was indeed a central hall, in addition to the corridor where he came, there were three other corridors, in three directions, one of which was lit up, and the other three were pitch black.

Instead of going to the lighted hallway first, Batman walked towards the closest hallway to him, and threw a flare at it, which he found was a dead end, except that there were two rooms on each side of the wall.

After entering the first room, there was a preparation room, with gloves, protective clothing, masks, face shields, etc., seeing these, Batman directly took out a gas mask and put it on, because he knew that there might be a biochemical laboratory ahead.

Sure enough, a radiation sign was painted on the door of another room on the same side, and at this time, the light system in the corridor was not lit, and looking at the situation in the preparation room, the entire corridor was powered off, which means that the door of this room is likely to no longer be radiation-proof and sealed.

Batman took out the reading device, but the amount of radiation displayed on it was completely unusual, and after a moment's hesitation, he decided to break down the door.

Although the door may no longer be closed, it still took some effort for Batman to open the door, and after successfully making a hole in the door, Batman walked in, and there was still no light here, and all kinds of experimental equipment were scattered on the ground.

There was no radiation source here, or rather, the radiation source had been transferred, and Batman frowned deeply as he looked at the broken container on the ground.

The entire laboratory was very ordinary, and there were no specimens or live animals used for experimentation, but soon, Batman found some information.

"No. 3221 Experiment Log 1, the subject has no obvious abnormalities today, and the reaction to eating and drinking activities is normal, and after discussion, increase the radiation dose ......"

"No. 3221 Experiment Log 2, today's subject has mild dizziness, nausea, decreased appetite, stiff limb activity responses, and a second increase in ......"

Batman flipped through it, it seemed to be an experiment log of a radiation experiment, which did not clearly explain what the subject and the radiation source were, Batman read all the previous parts, and then saw the last log.

"No. 3221 Experiment Log 35, the spread of cancer cells in the subject's body today has been uncontrollable, and it is judged to be incurable, and the subject has no obvious conscious activity, is unable to eat and drink, and has no physical activity response......"

"Conclusion: No beneficial mutations were observed in the 01 radiation source, and all subjects suffered from incurable cancer......"

After reading the rest of the summary, Batman put the information down, and he turned to leave the corridor, because he had just seen from the later records that there was a morgue in this underground base.

Although he had expected it, Batman still felt suffocated for a moment when he entered the morgue in another corridor and saw the dense morgue.

Judging by the level of wear and tear on the handles of the morgue, it was once overcrowded, and there could have been hundreds or thousands of people who had undergone such inhumane radiation experiments.

An angry Batman walked up and opened the cabinet of one of the corpses, and there was a "bang", and Batman instinctively rolled to the side, but nothing hit him.

Popping out of the sliding chest of drawers was a sign with red paint written all over it, which read: "Please go to the monitoring room at the end of Hallway 3, where I have a surprise for you." ”

A very rough smiley face is painted underneath the sign, and Batman doesn't have to think about it to know that it was left to him by the Joker.

Batman took a few deep breaths, and instead of doing it right away, he explored the morgue, but there were no bodies here.

The only thing he knew now was that the mysterious source of radiation could cause cancer in ordinary people, and as for what Lecks said, Leonel found that some kind of radiation could improve people's physique and intelligence, it looked more like a hoax.

After searching the other corridors, most of the other rooms were laboratories for various functions, but the equipment inside was a little dusty, and it looked like no one had used it for a long time.

Batman found a paper clue in the last laboratory, which was a mutilated document, but the information mentioned above was very important, they said that the so-called radiation source 01 was actually an alien mineral called "kryptonite".

Because some scientists have discovered that this alien mineral has special radioactivity, they want to study whether this mineral can mutate ordinary people, but after the failure of the first experiment, they did not give up, but conducted more experiments.

Batman doesn't know where they get their confidence and thinks that this radiation will have a positive effect on people, and perhaps, there is a lot of information behind it that he doesn't know.

After surveying all the rooms in this hallway, he proceeded to the next hallway, undisturbed by the Joker's prompts.

At the end of another dark hallway, there was a large door, exaggeratedly shaped to appear to lead to a large space, but there were no keyholes on it, and the miniature bombs did no harm to the door.

Batman tried for a while, and found that he couldn't open the door with his current equipment, so he made his way to the lighted hallway.

At the end of the hallway, Batman is confronted by three walls of surveillance screens, the light of which is focused on a chair in the center of the room.

As soon as Batman walked into the room, the chair slowly turned, but there was no one on it.

On top of the chair are three round bat dolls. and a whole bunch of bat lollipops.
