(ps. Burst progress 5155/5800)

It turns out that in the trial shijie, the level gap is very obvious.

Although it can't be seen from the superficial attributes, Xiao Yan of level 1 can completely crush his opponent without making weapons in the face of level 0 monsters.

The military dagger in his hand is even better than the dagger sold by Shijie no Tree, and the base attack power reaches 15.

Even if Xiao Yan only uses his current attributes, it is enough to increase the attack power of this dagger to a considerable extent, and dealing with these level 0 monsters with low defense in front of him is as simple as piercing tofu.

Moreover, in addition to the piercing effect, the military dagger also has an additional cutting effect, which allows Xiao Yan to add a cutting action after stabbing into the monster's body, which can not only make the wound bigger, but also increase the secondary damage.

With such a weapon, coupled with the control brought by high agility and the perception brought by high spirit, it only took Xiao Yan 15 minutes to kill 12 quest monsters, of which at least 6 minutes were spent finding the correct key on the keychain to open the door, in other words, Xiao Yan could kill a level 0 monster in less than a minute on average.

When he cleared 3 rooms and completed his mission, he was somewhat regrettably sure that the probability of dropping keys from these level 0 monsters was very low, at least so far, none of the keys had fallen.

"Mutant Research Mission Complete"

"You gain 100 Gene Points"

"Although you have killed a lot of Nobelis humanoid mutants, you have not found what you are looking for in these mutants, they are too smelly or poisonous, you need to think about killing more mutants, the key to open the door is in your hands."

"You triggered a new side quest, mutant anomaly"

"Mutant anomalies: You'll have to take out more of the Norbeli humanoid mutants, scrutinize the bodies of these mutants, and maybe make some surprising discoveries."

"Difficulty: Grade B"

"Quest: Kill more Nobelis humanoid mutants and find the 'Source of Mutation'."

"You don't know what the future holds, but it doesn't hurt to get rid of the monsters around you, at least you can be sure that when you leave here, these monsters won't sneak up behind you."

This is a very strange task, the difficulty suddenly jumped several levels, not to mention, there is no mention of what the source of mutation is, let alone what should be done after getting the source of mutation, Xiao Yan can only vaguely speculate that the source of mutation is mostly related to shijie on the surface.

Speculation is just speculation, Xiao Yan sat on the floor of a room for a few minutes, and when he confirmed that his body was no longer as tired as just now, he stood up, the keychain in his backpack, and frowned slightly.

There are still a total of 12 rooms on both sides of this passage that have not been opened, and in Xiao Yan's hand, there are still 11 keys left that have not opened the door, in other words, there is a room in the passage that has not been opened by a key.

Xiao Yan didn't think much about it, walked to the next iron door, and began to unlock the key again.

An hour later, Xiao Yan sat panting on the floor of the 11th room, completely oblivious to the dirty blood and pus on the ground.

From this room to the previous rooms, all the remaining monsters were killed by Xiao Yan, and even the treasure chest key of the Shijie Tree fell out, but there was never the so-called source of mutation.

Maybe these mutants are also on the surface, and in order to connect the entire main story, there are such side quests.

Xiao Yan thought like this, turned his head and looked at the 11th room,

Unlike the previous cramped room, which had two bunk beds, Room 11 was closer to the direction Xiao Yan wanted to move on, and the room was more spacious, with several radio stations in it.

From time to time, these stations emitted the sound of "zez", and next to the radio table, there was a blood-stained pistol.

Xiao Yan picked up the pistol and put it in his backpack, glanced left and right, but did not find the protective suit he was hoping for.

In fact, he stopped here from the beginning and didn't move on to find the suits.

According to the main quest, the shijie outside is a "ruin of a city after a nuclear war", which means that the shijie on the surface may be diffuse and terrible radiation, if you don't have enough protection to go out like this, maybe just appear on the ground, and the body will die because of these radiation.

Along the way, he never saw any protective equipment, whether it was the corpse soaked in the puddle or the small room with the door open, there were no such things, which made Xiao Yan finally hope that he would be in the passage closest to the ground.

He was going to be here, to find the protective gear he needed.

However, Zuihou's result still disappointed Xiao Yan.

The entire nuclear bunker doesn't seem to have any protective clothing stored at all, which is somewhat weird.

Xiao Yan rested in room 11 for a long time, and the tiredness in his body could not be dispelled, and it seemed that the recovery of physical strength was not a simple matter.

Two hours later, he left Room 11, and as he passed Room 12, he glanced at the already calm room, and behind the closed door, there seemed to be something different from all the monsters before.

And this guy is very powerful, he doesn't need to make any sound, just his breath can make Xiao Yan's hairs stand on end.

Thankfully the door was closed, he thought.

Continuing to walk along the passage for a while, there was already a faint sound of wind generated by the movement of air around Xiao Yan, different from the lifeless air of the underground passage, the air here was obviously fresher, and even vaguely smelled of earth.

From the passage just now, Xiao Yan didn't see the heavy lead doors that should be closed, the lead was thick enough to prevent radiation, but there was no such thing on this road.

From this point of view, there is no effective defense against a nuclear war from the outside.

Anyway, since he has already arrived here, it is pointless to turn around and go back to find any protective clothing, if there is enough radioactive material in the air on the surface, even if the air circulating around Xiao Yan is enough to kill Xiao Yan many times.

He let out a long breath, lifted his spirits, and strode forward again, and after a few minutes he could already see a small circular spot of light at the end of the road.

At this time, Xiao Yan didn't worry much, he stopped, and while letting himself rest, he called out the console of the Shijie Tree and inquired about the progress of the main line.

"Main Mission Progress: 21%"

This is a good statistic, and on the other hand, he made the right choice, otherwise there would not have been a situation where the main line progress would have been advanced.

"Hope is a good sign."

Xiao Yan whispered to himself.
