The next day, Gu Lin was woken up early in the morning by Elder Kun.

"Gu Lin, come, come and help Elder Ben!"

"Got it!" Gu Lin reluctantly opened his eyes, got up and washed up and went up to the second floor.

Elder Kun was in the secret room, and Gu Lin came to the secret room.

A pitch-black big ding, there is a big brazier at the bottom of the ding, and a strong flame is burning.

"What's it here? Why is it that it's a little thing, and the fire is so big. Gu Lin asked suspiciously.

"This is a flint, which can be used to generate flames with aura, and the size of the aura controls the size of the flame. Elder Kun explained.

"I see, if you throw a flint stone in the middle of a battle, I don't know what the effect will be. Gu Lin suddenly thought, will he burn the other party naked? A strange smile rose at the corner of Gu Lin's mouth.

When Elder Kun heard this, he said lightly, "You have this idea in others, and it's okay to use it to fight." ”

"Ah, I really can, haha, Elder you can give me a few more pieces later. Gu Lin rubbed his hands together and said with a grin.

Elder Kun suddenly raised his head, glanced at Gu Lin like Bai Chi, and said, "You think this flint is very cheap, do you know how much this small piece is worth? This small piece is enough to buy a city, and you want to ask me for a few, I don't have it, you can find it wherever you want." ”

"You can't buy a city for this small piece, you won't lie to me, that's all?"

Gu Lin thought, although I came from a small place, you can't tease me like this, but I am also a thinking person, how can I be deceived by you.

"You don't believe it?" Elder Kun knew what Gu Lin was thinking as soon as he saw his expression.

"Don't believe me, Elder, how old do you see me?" asked Gulin.

"About twenty or thirty!"

"Then you also know that I am not a child, why do you still lie to me?" Gu Lin despised Elder Kun for a moment and continued to study the others.

This big tripod is also extremely extraordinary, it is a quadrangular tripod, the whole gives people a sense of thick majesty, and the height is at the mouth of the ancient forest.

Gu Lin sighed in his heart that this was a good tripod.

At this moment, the elder continued to speak: "I lied to you or not, you will know later." Now that you help me control the size of the flint fire with my vitality, I will devote myself to alchemy. ”

"Elder, what kind of pill did you practice this time, is it an elixir to improve your strength?" asked Gu Lin.

But Elder Kun didn't answer, his expression had become very serious, and he was completely different from the two of them just now, he held the medicinal herb in one hand, and his eyes stared straight at the Great Ding.

Gu Lin knew that he had to try his best to cooperate at this time, because after all, he was here to be an alchemy boy, and he was not allowed to be idle. If he doesn't do it well, maybe Elder Kun will let him get out, then his elixir ......

Gu Lin stopped thinking about it and quietly waited for Elder Kun's orders.

A cloud of purple smoke gradually rose from the Great Ding, and Elder Kun immediately threw several medicinal herbs into the Danding.

"Little fire!" the elder shouted.

Gu Lin immediately gradually weakened the vitality injected into it, and the fire gradually decreased, and when it reached a certain point, the elder shouted again: "Stop!"

As a result, Gu Lin has always maintained this state of aura input.

After a while, I saw Elder Kun drop a few more medicinal herbs, and at the same time shouted: "Fire!"

Gu Lin suddenly increased the input of vitality again, knowing that Elder Kun shouted to stop.

"Fierce fire!"

Gulin ......

"Slight fire!"

Gulin ......

......

In this way, it lasted until the afternoon, and a purple cloud of incense gradually drifted out of the danding.

"It's done!hahahaha!!" Elder Kun laughed.

Gu Lin was extremely happy, after all, he had also contributed to the formation of this pill, and naturally he had a share of the credit.

"Elder, what kind of elixir is this, are you so happy?" asked Gu Lin.

"This is the Explosive Spirit Pill!" Elder Kun said with a big laugh.

He put the three Explosive Spirit Pills he had cultivated into a bottle and handed them to Gu Lin.

"Hold, this is for your self-defense. Going to the Heavenly Sword Gate this time is full of dangers, and it can be regarded as a little guarantee for you!" Elder Kun said.

"For me?"

An inexplicable emotion instantly welled up in Gu Lin's heart, he didn't expect that the elixir that he had worked hard to refine for a day was actually for his own self-defense, and for a while, Gu Lin was moved by the old man in front of him.

"When I was in Tianning Kingdom before, I saw others use this elixir, it is indeed very strong, and it can instantly increase the strength of using people, and then I found out that there is also this kind of elixir in the Xuantian Academy, I don't know if it is like this. Gulin said.

"Oh, that should be this kind of elixir, however, the elixir is also divided into grades, although the characteristics of the explosive elixir determine that he is only a second-level elixir, but if his quality is different, the effect will naturally be different. ”

"Grades, how are they classified?"

"The elixir grades are divided into one to nine grades, and the quality is divided into lower grade, middle grade, upper grade, and best grade. You just need to know that the explosive elixir I have refined will be stronger than what you have seen before. ”

After listening to this, Gu Lin had a certain understanding of the elixir, and with this explosive elixir, he did have more means to save his life, so he put this explosive elixir into a storage bag and stored it well.

"However, you have to remember not to use it unless you absolutely absolutely have to. Elder Kun said solemnly.

"Why? Why don't you use such a good thing?"

"Because although this elixir can instantly increase its strength, however, after the effect of the medicine, the user will fall into a period of weakness, if you can't kill the other party after taking it, then you have to choose to flee, only in this way can you survive. ”

"Isn't this just a chicken rib?"

Gu Lin thought that he had just been excited for a while, which poured cold water on him, and Xin Hao knew it, otherwise when he fought, he might die dead.

"It can also be said that it is also a bit of a guarantee. Elder Kun replied.

Gu Lin thought about it, and felt that it was still a little useful, when he was in Liulin Town, didn't that Liu Crazy Knife almost kill himself?

"And how long is this debilitating period, and how long can this medicine last?" asked Gu Lin.

Gu Lin thought that only by mastering the time well could he kill or flee the enemy before the weakness period arrived.

Elder Kun glanced at Gu Lin and replied, "This elixir can last for three quarters of an hour, and after three quarters of an hour, you will enter a period of weakness for a day, so you have to make good use of these three quarters of an hour. ”

Gu Lin nodded, understanding what Elder Kun said.

Three quarters of an hour! This time is not short, if you can't solve it in three quarters of an hour, then you still have to escape!

"Elder, there's something I want to tell you!" Gu Lin said with a sudden smile.

Elder Kun was stunned for a moment and asked, "What's the matter?"

"I want to learn alchemy!" Gu Lin said with a smile.
