The pure steel door opens slowly and silently under the influence of hydraulic power, allowing the outdoor sunlight to shine into the ground to dispel the coldness.

When Pei Renli and the other four walked out, the school janitor guarding the door hurriedly closed the door again, as if they were afraid that something would run out with them.

Suppressing the large golem means that there is no longer any obstacle to return.

Along the way, although no one was injured, their physical strength and magic power were severely exhausted, and they no longer had the ability to continue exploring.

Usually in this case, the adventurer team will choose to camp nearby, or even stay overnight, and continue exploring after the condition recovers.

However, everyone was reluctant to spend the night in that cold environment, and with their current skills, staying in one place for a long time was not a good choice.

Anyway, I'm not in a hurry. If I have the opportunity to go there again in the future, it's better to accept it as soon as I can.

So they immediately packed up all the loot and returned along the original route. Fortunately, they didn't encounter the Basilisk again and returned to the surface smoothly.

The biggest gain from this adventure should be that Pei Renli firmly believed that "knowledge is power". In addition to not slackening in the study of magic, he should also learn as much as possible about other aspects of information.

Without the intelligence advantage, let alone the large golem at the end, even the flaming skulls and basilisks they encountered at the beginning were enough for them to drink a pot, and the best ending would be just to run away.

Of course, in addition to spiritual gains, there are also many material gains.

A rune stone that may be a magic weapon, a stack of golem assembly drawings, more than thirty palm-sized rare metal ingots, twelve bottles of raw metal ore ground into powder, an extremely sharp short knife, and two sets that are not too heavy.

The alchemical instruments that can be carried away, as well as the most valuable loot, belong to the alchemy core of the golem.

Originally, the most valuable thing was the alchemy core of the large golem, but the implosion of the exploding crystal caused it to be severely damaged. Not to mention the technology required to repair it, the cost of materials alone was not as cost-effective as building a new one.

Not all of these things were exchanged for money. Vondar asked for a few pieces of cold iron.

This metal can destroy the regeneration ability of certain monsters, and is more easily enchanted than ordinary steel. It is a relatively expensive metal.

It seemed that the weakness of the mace in his hand when facing the golem hurt the dwarf's self-esteem. He planned to leave the school and borrow a blacksmith shop to make a weapon with cold iron by himself.

Most of the priests of Soulbreaker Moradin are very good at forging, because the shrine to Moradin is simply covered with iron felt, and the sacrificial ceremony is also closely related to forging. Coupled with the racial talent of the dwarves, wielding a hammer is considered a skill for Fondal.

Own job.

Gary also wanted to take the opportunity to ask Von Dahl to help build a new shield, but no matter how he collected the materials, he couldn't find enough materials, so he had to pick some tough shadow steel and asked Von Dahl to help add spikes to the shield and armor.

In this way, the shield in his hand can be regarded as a weapon instead of an armor, which circumvents his problem of not being able to use any weapons except the shield.

Alton couldn't put down the dagger of the golem. It was not only sharp, but also strong enough to tear through steel without curling the edge. Although it was not a magic weapon, it was definitely the best among the best.

And what Pei Renli wanted was naturally those two sets of alchemy instruments.

One of them is the magic crucible, which functions similarly to a small electric crucible. The only difference is that it needs to be activated by magic power and can melt metals with low melting points.

The other is a three-piece set of molds, carvings and polishing and carving. For Pei Renli, who currently has to rely on himself for everything, these tools will allow him to start studying another discipline of alchemy, which is the production of magic items.

The rest of the things will be handed over to the school staff, who will register them in a book. Whether they contact the original owners to recycle them or sell them, Pei Renli and the others don't have to worry about it. They can just wait and receive the dividends in the future.

The total income obtained needs to be divided equally into four parts, and then the value of the loot taken by each person is deducted to compensate other teammates. Alchemy instruments are the most expensive, and short knives are the cheapest. Therefore, if you do not count the golem assembly blueprints, you can probably still get it this time.

Twenty or thirty gold coins will only be less, not more.

The reason why the drawings are not included is because it is too difficult to value, and it is not clear whether the original owner will pay to take back the stack of instructions, so it is not included for the time being.

Counting the savings on hand, it should be enough to buy the special ink and parchment needed to make the scroll. If you study the battery life carefully, you can make great progress.

In general, although the first underground adventure was a bit awkward, I still made a lot of money.

Risk-takers do indeed make money, after all, they are risking their lives.

After settling the issue of the trophies, Vondahl and Gary planned to go to the teacher to apply for permission to go out, and then go to the blacksmith shop tomorrow. Pei Renli planned to go back to the dormitory to put down his backpack and other things, and take a shower by the way to prepare for lunch.

Everyone went underground early in the morning. Looking at the sun now, it's probably around ten in the morning. We can't make it in time for the third period, but we can definitely make it in time for lunch.

So everyone separated and walked towards their respective goals in the warm sunshine.

"Is there no one around here?"

On the way to the dormitory, Perenli looked around and asked Alton next to him in a low voice.

The latter nodded quite alertly:

"Don't worry, I also paid special attention to there being no one around."

After confirming that no one would see it, Pei Renli gestured with the seal, and a shadow that looked particularly dark under the sun exploded in his hand and quickly disappeared without a trace, revealing a dusty cloth bag.

This is extra money that is not included in the team's income.

Explosive crystals are restricted items and are not allowed to be bought and sold by unqualified people. If they are included in the team's harvest, the price will be severely suppressed.

As the saying goes, if you have a good plan, I have a trick. If you have a way to convert this thing into money, you can make a lot more money than going through the formal channels.

Alton quickly hid the cloth bag under his cloak:

"I'll ask the teacher for permission to go out tomorrow, and we can count the money the day after tomorrow at the latest."

"Be careful, that thing is extremely unstable."

Peri Renli's eyelids jumped at Alton's actions. If this exploded, they would have to take a plane on the spot.

"It's okay, I've done it before, I'm experienced."

"Okay, you won't be going out until tomorrow, so where are you going to hide it today?"

It's absolutely not okay to put it in a dormitory. It's too dangerous. If it explodes accidentally...

Alton didn't answer, just smiled:

"Of course I can hide it properly."

As he said that, he looked around like a thief, nodded to Pei Renli to leave everything to me, and then quickly left in the other direction.

Perrenli was still a little worried, but since Alton looked very confident, it was better not to get involved and just wait to count the money.

Calculating it carefully, Pei Renli already has several sums of money waiting to be received. The young lady who rescued him when he went to Muxing City said that he would pay the reward. It will take a few days to see the benefits of this adventure.

In addition, it should be a considerable fortune.

Mages cost a lot of money, especially mages who want to become stronger instead of just being a scholar. All aspects are very expensive.

It is unlikely that this money will be used to purchase magic items, but it is more than enough to purchase the tools and materials that Pei Renli urgently needs, so as to strengthen the combat effectiveness as much as possible, so that the upcoming Demon King Arena will be more confident.

Seeing Alton walking further and further away, Perenli shook his head and continued walking towards the dormitory.

Now there is only one question left. What happened to the still warm bonfire he found before?

–‐‐——–‐‐——

Theoretically, there should be no intelligent creatures in the school's underground research institute, and it is impossible to sneak in secretly.

The special secret lock requires a password and a special key to open it. Picking the lock is very difficult and will inevitably leave traces.

If someone really sneaked in, the matter would have spread all over the school.

Perrenli paid attention to this matter because after they entered the secret passage, they had a vague feeling of being spied on. To be honest, even he was not sure whether it was an illusion.

I asked Ravna and she found nothing.

Ravna, hiding in the shadow, could only hear and see. All other perceptions were temporarily blocked, so she could not judge.

He felt that the flaming skull and the basilisk that should not appear had something to do with this matter, but he couldn't figure it out for the time being.

After thinking about it for a while, I couldn't figure out the reason, so I could only put it into the category of unsolved mysteries.

However, although there was no result in this matter, the abnormality of the underground research institute was a fact that had been confirmed. After the school learned of everyone's reports, it immediately terminated other underground-related mission dispatches and prepared to wait for a while for the teachers to go in and take a look.

It depends on the situation and we will wait until it is confirmed that there is no problem.

The next day, Pei Renli still got up early despite yawning, preparing to start his inevitable 1,500-meter long run every day.

But unlike usual, Pei Renli came to the school playground today and saw many people gathering together and whispering. It felt like something big had happened.

After looking around, Pei Renli saw Korra. In terms of being well informed, this paparazzi bunny-eared girl did her job.

"What happened? Why is the atmosphere a little weird today?"

As a result, Korra asked:

"Didn't you hear the sound last night? Most of the people in the dormitory were woken up and shook."

sound?

Pei Renli really didn't hear it.

Even though he was already very tired from venturing underground yesterday, this was not a reason to stop him from continuing to have a bad liver. At most, he could go to bed two hours earlier than usual.

The exhaustion of the past few days has made him sleep so hard now that he might not even know he was dragged away by a wild beast in his sleep.

Seeing Pei Renli's confused look, Korra came over and whispered:

"Yesterday...to be precise, early this morning, the toilet suddenly exploded when the principal was getting up."

"……What?"

"It's true! I didn't spread rumors."

This is indeed a bit unbelievable. Korra emphasized the authenticity and said:

"I heard that the sudden explosion caused the principal to fly more than two meters high, and he was hung directly on the toilet partition. He almost fainted on the spot. Later, other teachers who heard the sound and rushed to him sent him for treatment, although he did not

What kind of injury is there, but everyone will know about it before dawn."

Korra smiled as she spoke, and her smile gradually became more sinister...

"What happened?"

Not far away, another student rushed to the playground. Korra saw this and hurriedly killed him:

"I know, let me tell you!"

For the loud-mouthed Korra, it would be quite uncomfortable if she was not allowed to broadcast this matter.

So Korra, who was talking to Perenli one second, disappeared from sight the next second, looking very busy.

At this time, the short Alton quietly came to Pei Renli's side and lowered his voice with a speechless expression:

"I hid the exploding crystal in the toilet water tank yesterday..."

There are no toilets in this world for the time being, but there are flush toilets, which are just squat toilets.

In terms of choice, Alton did nothing wrong. Soaking the exploding crystal in water can greatly reduce the risk of it exploding, but anyone who has seen the toilet water tank knows that the water tank is not empty.

"I obviously chose the toilet cubicle at the end that is usually never used. Who would have thought Mr. Principal..."

Before he could finish speaking, Perrenli interrupted Alton with a wave of his hand:

"What exploding crystal? I don't know, and neither do you."

"...Yes, indeed, the poor principal is so unfortunate."

"yes"
