Inside this door, which looked completely different from the other doors, was a small space like a storage room, but the things inside made Xu Xin's eyelids twitch.

The facilities in the house seemed very complete, with wooden tables, wooden chairs, wooden beds, and a wooden cabinet. The door of the wooden cabinet was closed, and it was unknown what was inside.

Of course, these are not the most attractive things to Xu Xin, because in the corner of this room, there is a metal facility that looks like a workbench. The table top is round, and the whole facility is shaped like an hourglass.

The most special thing about this facility is that there is a small screen standing on the bottom of the table.

Xu Xinke is very familiar with this type of workbench.

"...a workbench for making a tree house?" Xu Xin didn't expect to see a tree house workbench here.

Whether it is a synthesis table or a weapons and armor manufacturing table, there is a small upright screen on the table for him to view the production list, which is basically exactly the same as the workbench in front of him.

There were no stone statues or mutant beasts in the house. Xu Xin walked into the house gently, came to the workbench he had never seen before, and reached out to touch it.

[Mutation Potion Synthesis Station (Blue): Can synthesize potions that mutate beasts.]

"Is this true?" Xu Xin actually found a tool that can transform wild beasts into mutant beasts!

He immediately clicked on the small screen and a familiar picture appeared, but there was only one production project on the entire synthesis platform.

Mutation Potion (Blue): This potion has a 100% chance of transforming a beast into a low-level mutant beast. Requires 5kg of contaminated mutant beast meat and 1 glass bottle.

Using contaminated mutant beast meat, you can synthesize a potion that can completely mutate the beast!

This contaminated mutant beast meat was not the meat of bats and rats. Xu Xin had only obtained this kind of meat from the blood-marked rabbits and cats he had killed before.

This kind of meat is extremely attractive to wild animals, but it is also very poisonous. Wild animals that eat this meat are very likely to be poisoned to death, and there is only a very small chance of mutation.

However, this synthesis platform made the possibility of this mutation 100%! Although it only mutated into a low-level mutant beast, it made the ability of the contaminated meat from uncontrollable to controllable. He could completely use this ability to create mutant beasts that would work for him in accordance with the contract!

Good stuff! It was this glass bottle, which he had never seen before. Glass must be made from sand, but he had never seen any tools that could make glass.

Wait, a furnace! Maybe a furnace can make glass. He'll try it when he gets back.

Xu Xin turned to look at the closed wooden cabinet beside him. The cabinet next to the crafting table, inside, could it be...

Xu Xin habitually turned sideways and opened the wooden cabinet.

“Whoosh!”

"oh!"

"Hmm!"

Three crossbow arrows shot out from the open wooden cabinet and flew past Xu Xin. With a neat "click" sound, the iron crossbow arrow heads were embedded into the stone wall behind!

Xu Xin was so frightened that he broke out in a cold sweat.

There is a mechanism here!

Luckily, he was cautious and subconsciously pulled the cabinet door open sideways, otherwise the crossbow arrow would have hit him head-on! There were no traps in the front, only here. If he hadn't been so cautious every time, he might have really been caught here.

"Keke, why didn't you notice the danger this time?" Xu Xin rubbed Keke's little head.

"Hmm?" Coco tilted her head and shook it.

It seemed the little creature could only sense dangers related to living things, and couldn't detect anomalies with purely mechanical devices like this. Keke hadn't noticed when Xu Xin nearly fell in the maze, but when mice and toads appeared, it always sensed danger in advance.

Looking inside the wooden cabinet, the cabinet has three layers. In the middle of each layer is a crossbow fixed to the cabinet. The crossbow trigger is connected to the cabinet door with a thin wire. As long as the cabinet door is pulled a certain distance, the thin wire will pull the trigger. The three crossbow arrows were shot out in this way.

It's a very simple mechanism, not a professional trap. It looks more like it was set up by a survivor.

However, Xu Xin's attention was quickly attracted by the resources in the three-layer cabinet.

"Is this... a mutagenic potion?"

On each layer of the cabinet, there were two bottles of light red medicine, which were contained in glass conical bottles and the bottle mouths were plugged with ground stoppers.

Xu Xin reached out and took down a bottle of medicine.

[Mutation Potion (Blue): A potion that can make beasts 100% likely to become low-level mutant beasts.]

Sure enough, it was a mutagenic potion. There were six bottles of mutagenic potion in this cabinet.

Xu Xin immediately put the six bottles of potions into his backpack, along with the three green-level crossbows. He then went to the mutation potion synthesis table and wanted to put that synthesis table into his backpack as well.

Although it is unknown what type of metal the synthesis platform is made of, it is relatively small, so it is not heavy. Putting it in the backpack does not affect Xu Xin's movements at all.

But the moment he lifted the synthesis table off the ground and put it into his backpack, he suddenly felt the ground beneath his feet shaking.

He looked at the original location of the synthesis platform. There was a protruding stone there. It seemed to have been pressed down.

"...No way, could it be that some mechanism has been triggered again?" The corners of Xu Xin's eyes twitched.

"Oh, oh, oh!" Coco, who was already a little drowsy, suddenly cried out quickly, jumped off Xu Xin's shoulder, walked to the door and looked towards the corridor.

Xu Xin also leaned out to look.

The ground shaking became more and more intense, just like the previous staircase passage.
