The fire gathering talisman is the key point in the foundation of alchemy. Because at present, only this thing can directly allow Yang Tao to have enough alchemy flames.

This is a consumable item, so Yang Tao deliberately prepared enough materials to be able to refine enough spirit runes.

"This fire gathering talisman is indeed also a primary spirit talisman, that is, it can condense flames. And the time is not very long, only half an hour. ”

Yang Tao silently recalled the total information in his mind, slowly sorted it out, and adjusted his inner mentality, so that his heart continued to return to peace.

"When you are alchemizing, it is best to use three fire-gathering talismans. This Dan furnace is so large, at least three of them are needed to directly balance the heat in each place. ”

Yang Tao slowly looked at the Dan furnace, this time he had to consider a lot of problems. And the main purpose is to practice the fire gathering charm. Then test whether this Dan furnace is feasible or not!

As for the red fruit and other medicinal herbs, Yang Tao didn't bring them in this time. The red fruit grows very well in the spiritual field, of course, when it is to be used, it is best to take it out.

"Let's get started. ”

Yang Tao took a deep breath, and then unpacked the package. The pungent aura such as black flames immediately sprinted into the three-meter-high basement.

"Fortunately, I deliberately didn't let them cement the ground or anything, otherwise it would be troublesome. ”

Yang Tao directly took a shovel and dug a rectangular pool on the ground. Then I put the black powder directly into it, and then slowly added a little bit of mercury.

This process is a blend and requires the care of non-hidden. All of these things, whether it is the time of joining, or the number and number of additions, are very particular.

If you are not careful, it will lead to a tragic fate.

In this whole process, Yang Tao's nerves are jumping tightly, he has to constantly observe the changes in the entire pool, every corner, if there are bubbles in that place, he must add mercury, so that the whole pool can be balanced!

Time is constantly passing, and in this process, Yang Tao refers to being able to passively observe and add things, but not to take the initiative to dominate. Because he doesn't have that kind of strength at the moment!

At this moment, Yang Tao completely belongs to the kind of person who is doing a very complicated experiment. I need to watch the changes in the experimental materials all the time, and I can't afford to wander the slightest.

"Whew~"

Knowing that eight hours ago, Yang Tao breathed a heavy sigh of relief, because he finally took the most difficult first step.

Inside the pool, there is a gray pasty object at the moment. It was like a paste, and it was still flowing, and the smell of black powder that began was completely gone at this moment.

"It's really nerve-wracking, but it's okay, there are no problems. ”

Yang Tao rubbed his forehead, although he was struggling at the moment, he couldn't stop. The following actions must be followed, otherwise, once this gray paste thing solidifies, it will be invalid.

And at the moment, this thing is also very unstable, the slightest confusion, it will explode directly, and it is a big dangerous item.

Soon, Yang Tao directly took the rune paper and put it into the white paste.

On the rune paper, Yang Tao has already drawn the corresponding simple formation, but this is difficult for Yang Tao, and among all the rune paper, Yang Tao failed twice.

Inside this rune paper, the gray thing will continue to melt. In other words, in fact, the gray thing is the carrier, and the rune paper is just an external form.

At this moment, the rune paper was on the top, and at the same time began to slowly glow, constantly absorbing the white paste-like thing.

At this time, Yang Tao began to add other materials, and each time he added one, the rune paper could sink one point. This process, although not as difficult as the initial fusion of mercury, is not so simple.

Yang Tao must control the rhythm and work hard to make the rune paper sink evenly. This is a problem, because it is a gray paste-like thing, if the rune paper sinks, it will definitely be covered by the gray substance, so how can Yang Tao observe the speed of sinking?

There is no other way here, you can only use the primary Heavenly Eye Talisman!

Although Yang Tao has a certain fear of this talisman. But at the moment, there is no other means. Yang Tao pointed out that he could fight, and at the same time secretly used all his strength to constantly come towards his eyes, so as to moisten his eyes!

"It's finally okay. ”

Yang Tao's eyes were already full of bloodshots. A tear of blood also appeared in the corner of his eye, but at the moment he still did not close his eyes, and confirmed it several times.

He felt a pain in his eyes, as if they were about to tear. Inside his head, there was a feeling of dizziness, but at this moment Yang Tao was laughing!

Because all that's left is waiting.

Another eight hours have passed!

The contents of the pool slowly disappeared and merged into the middle of the rune paper. During this time, Yang Tao also seized the time to meditate and recover.

"It's done!"

Looking at the gray-white rune paper at the bottom of the pool, even at this moment, his eyes still hurt, but Yang Tao still stood up directly and picked up a piece of rune paper.

"That's right, it's finally possible. ”

Yang Tao held back the excitement in his heart, and his eyes kept blinking. Because of the pain! The power of the primary Heavenly Eye Talisman was still unbearable for him at the moment.

"Then comes the most dangerous time. ”

The rune paper is ready, and so is the Black Lime. Next, it's time to draw the symbols.

At this moment, the rune paper is like the black part on the top of the fire box. The black lime, on the other hand, is the tip of the fire. At this moment, Yang Tao has to draw a talisman like a match.

If the force and speed are not well controlled, it will ......

"Bang!"

The brush in Yang Tao's hand was directly blown off, and his hand was also numb by Fu Zhen. The whole arm and ears, are buzzing!

"Damn, it was a failure. ”

Yang Tao gritted his teeth, even if he gritted his teeth at the moment, he couldn't feel the pain a little. I played hard in my hand, and then took out a brush again, this time I got less black lime than at the beginning.

"Hey, it's halfway, victory is in sight!"

After seeing that his talisman had been completed for a short time, Yang Tao suddenly felt excited. His hands trembled slightly!

"Bang!"

Sure enough, it failed again. This time it was okay, there was not much black lime on it. But it also made Yang Tao's hands numb for a while......
