There was a lot of stagnant water on the ground inside the cave, covered with green moss, Alan hurried to move forward as soon as possible, the fire element in his body couldn't support it for too long.

After about fifty paces, Eren entered a large man-made space, and due to the large space, Eren's fireball could only spread ten steps away, and ten steps away it was still extremely dark.

Directly condense the fireball to the size of a fist, and the whole picture of the space is now displayed in front of him, there is a stone bed on Allen's right, and there is a dry skeleton sitting cross-legged on the stone bed, which is probably the owner of the cave, but he died here for some reason.

In front of Alan was a large stone platform, on which there were many things, covered with dust, this was probably this dry bone thing, without touching this dry bone at will, Alan walked towards the stone platform.

At the moment when Alan walked forward, there was a movement behind him, and Alan seemed to have eyes behind him, and his body quickly avoided to the right, only to see a black shadow flash from Allen's original position and rush to the bottom of the stone platform.

It's a mutant giant rat! At this time, the mutant giant rat's two red eyes stared fiercely at Alan who had broken into his territory.

Alan Judging from the speed of the mutant giant rat just now, it is still a low-level magical beast, and he didn't throw the fireball in his hand to finish it directly, and now Alan is already a middle-level knight, but he hasn't entered much actual combat, and he has only made moves with other knights in the territory every day, and today Alan decided to practice this mutant giant rat.

In an instant, the missing rat rushed towards Eren again, stretching out his front paws, trying to grab Allen's throat with his sharp front paws, but Alan turned and kicked the rat's belly exposed in the air, kicking it against the cave wall.

"Squeak!" the mutant giant rat let out a scream, blood spilling from the corner of its mouth.

Allen's strength was close to a beating, and the tremendous force kicked the giant rat in the stomach, inflicting internal injuries on it.

The demented mutant giant rat trembled and crawled up, and continued to rush towards Allen, but due to the previous injury, the giant rat's movements were even slower.

Alan was a little disappointed, the low-level demonic beasts were a little too weak to play the role of sparring at all, and after kicking the giant rat on the head and killing it, he didn't care about it, and Alan came to the stone platform.

There are many bottles and cans on the stone platform, and some of the wooden bottles have no content, and some have stoppers. Between the bottles and cans, Alan found a book full of dust. Thankfully, the book was made of a kind of animal skin, otherwise Alan wasn't sure if he would have survived in this damp environment.

Wiping the surface of the book, Alan saw the familiar Terran blood-colored text.

"Gabriel's Diary" It seems that the owner of the cave is named Gabriel, and has a habit of keeping a diary.

The words on the book are a little blurry, but they are legible.

——

On the 5th of January in the 89th year of the Principality of Cairn, I came to the Black Dragon Mountains, and I found a suitable place to build a place to live.

............

On October 3rd, 89 years of the Principality of Kane calendar, I had prepared all the materials and started preparing for the first experiment, I don't know if it would succeed, but I am running out of time.

March 8, 91 year of the Principality of Cairn, why? Why does it always fail?

............

Principality of Kane Wind 92, June 8, this is my last chance......

——

The contents of the diary are only from the 89th to the 92nd year of the Principality of Cairn, and this year is the 219th year of the Principality of Cairn, which is more than a hundred years ago.

From the diary, Alan learned that this man named Gabriel was not only a high-ranking knight but also an excellent pharmacist, and he came to the Black Dragon Mountains when his life was approaching, intending to concoct a potion that allowed him to break through the elemental knights, during which he had been sitting and experimenting, but looking at the dry bones on the stone bed, it was clear that he had failed in the end.

From Gabriel's confusion at the beginning to his final despair, it can be seen that it is difficult to break through the elemental knights, and Gabriel mentions the methods of the elemental knights in his diary, one is to take a special magical plant fruit, and the other is to configure the same magical beast bloodline as his own element.

It seems that Gabriel didn't get one of the two, so he came to the Black Dragon Mountain Range to try to make a potion that could make him break through.

However, Alan really doesn't have to worry that there is no way to break through the elemental knight in the future, as long as he advances the flame microphone to the rumored transcendent species, it is estimated that he can break through the elemental knight.

Through the diary, Alan also knew that the bottles with corks on the stone platform contained the last potion that Gabriel had refined, and under Allen's observation, the two wooden bottles suddenly attracted Allen's attention, just because the bottles of the two wooden bottles had a hole that had been bitten open, and the potion inside had been lost.

Found it, and now Alan has discovered the source of the mutation of the giant rat, and it can be clearly seen that the two holes should be bitten by the rat, which is also the reason for its mutation.

Thinking of this, Alan couldn't help but breathe a sigh of relief in his heart, as long as it wasn't a large-scale mutation, the two bottles of potions should be the culprits who created the two mutant giant rats, but Alan still planned to take these potions away, although these potions were failures, but the ability to mutate animals was also a useful thing.

Sensing that there was no other danger, Alan called Battenbad in and told them to fight the giant rat carcass, and the other of them walked out of the cave with the remaining eight vials of potions.

After letting Battenbad leave the cave entrance, Alan prepared to bury the cave entrance, and after a while, Allen, who used the fire element spar, finally replenished the fire element consumed in his body before.

He turned the fire element in his body to gather in his fingertips, and saw a fireball grow in Ellen's fingertips until it swelled to twice the size of a human head, and then stopped, and with Allen's operation, the fireball hit directly above the hole.

"Boom!"

As a violent explosion sounded in my ears, the entrance to the cave collapsed, and a large number of leaves fell from the surrounding trees.

Seeing this scene, Bartonbard was shocked, he didn't expect the baron to be so strong, this is an element that can only be used by high-level knights, even the Viscount Berner of the Viscount of Musen is only a middle-level knight, and now his own baron has become a high-level knight, and he has just arrived at a low-level knight, and he is ashamed in his heart, and he can't help but revere Allen even more.

"What are you two doing, what are you doing, let's go!" Alan reminded the two of them with wide eyes and shocked eyes.

"Yes, Yes, Lord Baron!"

Only then did the two of them come back to their senses and hurriedly responded, but the reverence in their eyes could not fade.

Looking at the hound, which had been frightened and hiding behind the tree with its tail shrunk, Alan had no choice but to grab the chain around his neck and carry it back to Fengguo Village.

After returning to Fengguo Village, Alan told the guard Sam that the monster had been eliminated, telling him to inform the villagers as soon as possible, while Alan and Battenbad rode out of Fengguo Village on horseback with the potion and the giant rat corpse.
