Chapter 1665

The door of the room had unsurprisingly been blown down. After Harley rushed in excitedly, little Bruce looked back at the doorknob with a lock hanging on it. The lock hanging on it was very ordinary, just like the metal lock hanging on the iron gate of the courtyard's outer wall, and it looked like it needed a suitable key.

But the door wasn't even made of steel; it was just a common wooden door in the castle. Little Bruce had no doubt that a trained agent could knock the door open by bumping into it a few times with all their might.

This gave little Bruce an understanding of the difficulty of this trial.

The tree demon in the first level seemed very dangerous, but it actually had too many weaknesses. It would only attack those who wanted to break in by force without a key. In other words, as long as one could find the key, they could skip the level, and it seemed the key should be hidden somewhere in the school, and the process of obtaining the key was not dangerous either.

Either break the trick with force, find something to knock the door open, or simply use explosives to blow the door open like Harley, or deal with it with flexibility and agility, relying on the advantage of a child's smaller size to drill under the tree demon's arm and lure it to attack the wooden door, which could still smash the door open.

Just as little Bruce was thinking while walking into the room, he heard Barry let out an exclamation. Turning his head to look, Barry grabbed the somewhat excited Harley and said, "Take that box of explosives of yours further away. This place is full of glassware. It'll be a disaster if you blow it up!"

Little Bruce stepped over the wreckage of the wooden door and truly walked into the room, and then he discovered that this was a room full of bottles and jars.

Tall shelves reaching the ceiling were embedded in the four walls, and glass jars were neatly placed on the shelves at different heights. Some were wide-mouthed bottles, some were narrow-mouthed bottles, some looked like round-bottom flasks, and some were more similar to small basins, but in any case, the material was exquisite and fragile glass.

Little Bruce hurriedly rushed up and grabbed Harley's other arm, stopping her from pulling the grenade, because there was no second door in this room besides the one they had entered through.

"What if there's something behind the wall?" Harley said, unwilling to give up.

"What if there isn't?" Barry grabbed her tightly to prevent this crazy girl, who seemed particularly excited due to the violent explosion just now, from using explosives to destroy everything in the room.

"It seems this is a puzzle." Little Bruce looked up and surveyed the glass utensils all over the walls, and said, "Someone had long ago anticipated that you would use explosives to break in. If you really make a mess of this place, the door might never open again."

"Is this the reason why you insisted on me using glass jars to hold those plants?" Pamela behind the screen turned to look at Schiller and said, "You guessed that someone among them would inevitably want to resort to violence, and you didn't want them to crack every level in this way."

"I was hoping to save the school some funds for building repairs." Schiller shook his head gently and said, "Let a real Gotham lunatic bomb this place, and even if we had another world's richest person, it wouldn't be enough to compensate."

"In fact, it would be enough." Bruce said, but soon he shook his head and added, "It's just that the elves in the Maia world need to rest, otherwise they would be exhausted to death."

"So what kind of puzzle is this?" Constantine asked, "Do they need to identify the properties of these plants?"

"Yes, and the remaining part is a simple arrangement puzzle." Pamela nodded and said in a calm tone, "It's all knowledge I've talked about in class. As long as one person listens carefully, they will definitely be able to do it."

"It looks like an arrangement and classification puzzle." Little Bruce said after looking at all the glass jars on the shelves on the four walls: "If I remember correctly, the plants in the entire room should be divided into four categories, namely potion raw materials, alchemy catalyst raw materials, ritual raw materials, and non-reactive raw materials."

"I remember it was mentioned in the magic botany class." Barry touched his cheek. He also looked around and said, "But it didn't mention so many types of plants at all. I don't recognize more than half of them. Perhaps it was mentioned in the senior classes."

He turned to look at Harley. Harley blinked, walked past the four walls, and said, "About half of these plants were mentioned in class, and the other half were not involved."

"But we can deduce it." Little Bruce sighed softly and said, "Professor Pamela once mentioned in class that plants growing in a certain world have similar properties and appearances and can be regarded as plants of the same genus."

"According to the appearance, color, and magic performance of the plants, we can also see their general effects. Let's take the bottles down first."

There were two ladders in the corner of the room, obviously for the convenience of students coming here to take all the jars down for inspection. The three of them took all the glass jars off the shelves one after another and put them on the ground, and Harley began to make a preliminary classification for them.

Harley was in a higher grade and had more classes. The magic botany class took nearly two months to teach students to identify plants that often appear in the magic world and understand their effects. Harley classified all the plants she knew, and the next thing was very simple.

When all the plants whose properties could be determined were put together according to the four classifications, anyone could see the similarities between them.

Potion raw materials are usually closer to the stems of herbaceous plants, such as the spiral grass that Barry and the others saw in the first class. That is one of the most typical potion raw materials, characterized by being soft, small, and having weak magic light.

Alchemy catalyst raw materials usually have extremely strong magic performance, with magic light filling the entire bottle, and the manifestation forms are mostly flowers and soft leaves, with appearances more similar to ordinary plants in the non-magic world.

Ritual raw materials have extremely strange shapes, either looking like withered fingers or like eyeballs or animal claws, and their exteriors often grow tumors and pustules, just like the kind of plants that would appear in dark swamps in horror novels.

And non-reactive raw materials refer to those plants that will not react with anything made from the above plants. They can be used to make containers, stirring rods, and other utensils that need to be in frequent contact with medicinal liquids. Naturally, most of them are cut pieces or branches of woody plants, which are hard and dry enough, and dark in color.

"Only one problem remains." Harley looked down at the sorted bottles and jars and said, "Where should the four types of plants be placed on the walls?"

"The one with the smallest quantity must be placed on the wall with the door, because that wall has the fewest shelves." Barry suggested.

Little Bruce snorted and said, "Your brain turned for once."

Among the four types of materials, the one with the smallest quantity was the non-reactive raw materials, so the three of them used the ladder to place this part of the plants on the wall next to the door. After putting them away, Barry let out a breath and looked at Harley, saying, "It's a good thing you didn't blow up the shelves on this wall, otherwise we would have failed before we even started."

Harley, however, revealed a smile, shook her head, and said, "It's not that simple. Obviously, there is another way to solve the puzzle in this room."

Harley hugged her arms, turned back to look at the bottles and jars on the ground, and said, "If I'm not mistaken, several of all the plant raw materials here can be combined into a special medicinal liquid. This potion should also be able to make the exit appear."

"But this risk is very high." Little Bruce said, "Because you don't know if they can return to the bottles and trigger the mechanism of the arrangement puzzle after pouring the raw materials out of the bottles, so unless there are absolutely no clues or the shelves are damaged, we don't need to use this method."

Harley nodded and said, "Although I do like to make a big scene, I'm not without a sense of proportion. I guessed that there might be some important things in the room, so I deliberately avoided the walls when throwing grenades. It worked. If we were to brew potions here, all of our clothes would be stained with a strange smell."

After speaking, the three of them began to study the remaining three walls, and then Harley discovered a rune in the corner at the bottom of each shelf. There was no puzzle to solve here; the meaning of the rune was the type of plant.

After spending a little more time putting all the bottles and jars in their respective categories, magic light bloomed in the center of the floor, and a door slowly opened. Below it was a pitch-black tunnel, and it was impossible to see where it led.

"Alright, it seems I can't take all these big babies of mine down." Harley looked at her cart of munitions with some regret and said, "In a situation where it's uncertain how deep it is below, I can't dump this stuff all at once. Once the safety is triggered, it will cause a chain explosion, and it would be a pity if it broke."

Harley picked and chose from the cart, took out three pistols, handed two of them to the other two, took out a few grenades and put them in her pocket, and finally took a shotgun and carried it on her back, tossing her head toward the door in the center of the floor.

Little Bruce glanced downward, but at this moment Barry said, "I'll jump first. In case there's any danger below, I can warn you."

Little Bruce opened his mouth, seemingly wanting to refute, but Barry interrupted him and said, "At least one thing you're right about: the brains of you two are precious treasures, and it wouldn't be good if they were broken."

Barry jumped down directly. Harley revealed a slightly neurotic smile at little Bruce and said, "These idiots are like this, right? Always feeling guilty for not being able to contribute to the team, soft yet hard, like a sponge soaked with tears."

"I reserve my opinion. They are like stones, hard, stupid, and useless, it's just that this Mr. Allen was just washed up on the river beach and doesn't know that his life will continue to be so stubborn until he becomes as annoying as those stubborn adults."

After speaking, little Bruce also jumped down. Harley shrugged, glanced at the air where there was nothing, and then said, "I wonder who will eventually become a stubborn adult."

When Harley's figure also disappeared into the door on the floor, Constantine smiled and looked at Bruce, saying, "Yeah, who? I raise both hands in agreement that it's definitely not Batman."

And Bruce turned to look at Schiller. Schiller tilted his head slightly to size Bruce up and said, "But too many whimsical ideas might not necessarily be better."

"Some people's whimsical ideas are easy to see, while others are always carried out silently. Except for themselves, no one can see where the happiness lies, right? Professor?"
