One Heart Dan!

The quasi-four-grade elixir, the main material is the one-heart tree, so it is called the one-heart pill, which is extremely difficult to refine, and it is more than ten times that of the general third-grade high-grade elixir, so it is called the quasi-four-grade elixir.

Once he was able to refine the One Heart Pill, it meant that the cultivator was not far from the realm of the Four-Rank Alchemy Grand Master, and it could even be said that he had already stepped into the ranks of the Four-Rank Alchemy Grand Master with one foot.

And the Great Grandmaster of the Four Grades of Alchemy, even in the entire Dark Night Islands, belongs to a group of people who are high in the sky.

In order to refine the Yixin Pill, Jiang Xincheng took a good rest and restored his spirit to the peak, and then walked into one of the hundred and ten underground alchemy rooms of Liujiang Palace and began to refine the Yixin Pill.

The same materials were placed around Jiang Xincheng's body, and there were no less than hundreds, each material needed to be placed in a different order, and it also needed to be in a certain order in the process of refining, and the handling was also different, it was definitely complicated, and without the power of the divine soul that was strong enough, he couldn't remember the refining process of so many spiritual materials and spiritual grasses at all.

However, with the assistance of the artifact Sheng Tang, Jiang Xincheng didn't need to spend energy on this, because the artifact Sheng Tang would remind Jiang Xincheng at any time what to refine next when refining the Yixin Pill, which invisibly made it much easier for Jiang Xincheng to refine various elixirs.

In addition, the artifact Sheng Tang can also help Jiang Xincheng to deal with various spirit grass spirit materials more accurately, so that there is not much deviation from it, and at the same time, it can help Jiang Xincheng observe the refining of the spirit grass elixir at all times through the power of the divine soul, and respond in a timely manner, speeding up or slowing down the operation of the yuan power and the power of the divine soul in Jiang Xincheng's body, so as to make the refining of the elixir more than ten times easier.

The first difficulty in refining the Yixin Pill is to temper the Yixin Grass with the Thousand Fire Fruit, so that the medicinal power of the Thousand Fire Fruit can be perfectly integrated into the Yixin Grass and become a part of the Yixin Grass, and it cannot destroy the medicinal properties of the Yixin Grass, and it is extremely difficult to achieve a perfect fusion between the two without interfering with each other.

It's like two streams together, if you want to flow together, but the streams don't merge, it's a fantasy for ordinary people, but in the alchemy world, it's just a slightly more difficult alchemy technique.

Thousands of fire fruits refining grass, this is the name of this difficulty.

Controlling the fire of Yuan Li, Jiang Xincheng put the same spiritual material into the Taishang furnace and slowly processed it, I don't know how long it took, Jiang Xincheng directly threw the Thousand Fire Fruit into the fire of Yuan Li.

As the Thousand Fire Fruit fell into the fire of Yuan Li, the Thousand Fire Fruit suddenly burst into flames, releasing a flame-like medicinal smoke while burning, and at the same time as the Thousand Fire Fruit burned, Jiang Xincheng had already thrown the Yixin Grass into the Taishang Furnace.

The divine soul fluctuated, and the medicinal smoke that controlled the Thousand Fire Fruit like an arm command floated towards the Yixin Grass, and soon enveloped the Yixin Grass, and penetrated into the Yixin Grass little by little.

Jiang Xincheng frowned, the artifact Sheng Tang was running to the extreme, monitoring the situation of the medicinal smoke merging into Yixin Grass all the time, and once he found that something was wrong, he would immediately remind him, so that Jiang Xincheng would not have to stare at it every minute, he could relax a little and recover the power of the divine soul and the power of the Yuan Force.

I don't know how long it took, a flowing line of fire appeared in the Qingyingying Yixin Grass, this line of fire was clear and clear, and it was incompatible with the Yixin Grass, but it flowed in the Yixin Grass, which made the Yixin Grass begin to undergo strange changes, and when this strange change reached a certain level, Jiang Xincheng put away the Thousand Fire Fruits.

Thousand Fire Fruit Refining Grass, this step is considered a success, and then it is time to integrate all kinds of spirit grass elixirs into the One Heart Grass little by little, and these spirit grass spirit materials do not need to be perfectly fused like Thousand Fire Fruits, but also have to be perfectly separated, so it is much easier.

However, as more and more spirit grass spirit materials are integrated, the difficulty of fusion will become higher and higher, and this time Jiang Xincheng needs to integrate seven hundred and twenty-three spirit grass spirit materials into the one heart grass in different ways, you can imagine how difficult it is, this is also the second major difficulty in refining the one heart pill.

The first spirit grass...... Perfectly blended.

The second spiritual material...... Perfectly blended.

The third spirit grass...... Perfectly blended.

……

The hundredth spirit grass...... Perfectly blended.

One hundred and one spiritual material...... Perfectly blended.

The One Hundred and Second Spiritual Material...... Perfectly blended.

……

As time passed, Jiang Xincheng fused more and more spiritual grass and spiritual materials, and the number gradually exceeded five hundred, and Jiang Xincheng's difficulty in fusing spiritual grass spiritual materials became more and more difficult, and sweat gradually appeared on his forehead.

Six hundred and one spirit grass...... Fusion.

Six hundred and two spirit grasses...... Perfectly blended.

Six hundred and three spirit grasses...... Perfectly blended.

……

700 Spiritual Materials...... Perfectly blended.

Seven hundred and one spiritual material...... Perfectly blended.

Seven and two spirit grasses...... Fusion.

……

At this moment, the role of the artifact Sheng Tang has been exerted to the extreme by Jiang Xincheng, and the amount of Yuan Stone consumed per minute is staggering, but it is nothing compared to refining the Yixin Pill.

Jiang Xincheng's spirit had been concentrated to the extreme, he didn't dare to be distracted at all, his face was solemn, his brows were furrowed, and he felt that he was about to reach his limit for the first time.

You must know that the fusion of more than 700 kinds of spiritual grass spiritual materials is generally needed to refine the four-grade elixir, but because the Yixin Pill is too complicated, it also needs to fuse more than 700 kinds of spiritual grass spiritual materials, and the number and difficulty of fusing spiritual grass spiritual materials are no less than some four-grade elixirs.

If it weren't for the help of the artifact Sheng Tang, I'm afraid Jiang Xincheng wouldn't be able to do this at all, let alone refine the Yixin Pill of the Quasi-Fourth Grade.

Seven hundred and eleven kinds of spirit grass...... Fusion.

Seven hundred and twelve kinds of spirit grass...... Barely fused.

Seven hundred and thirteen kinds of spirit grass...... Barely fused.

……

At this time, Jiang Xincheng stopped fusing because the artifact Sheng Tang had already begun to remind Jiang Xincheng that there was already a problem with this one-heart pill that was barely half-refined, and if the next spirit grass spirit material was not fused well, I was afraid that there would be a danger of blowing up the pill.

The next kind of spirit grass spirit material must at least be perfectly fused, so that it is possible for this one-heart pill prototype to get rid of the danger of fried pills, but Jiang Xincheng's grasp of the perfect fusion of the next spirit grass spirit material is less than one percent, even if there is the help of the artifact Sheng Tang, it only makes this grasp increase to about one-tenth.

Should it be fused or not?

Jiang Xincheng hesitated, after thinking for a moment, Jiang Xincheng decisively put this Yixin Pill prototype up for the time being, not ready to continue to fuse, the quasi-four-grade elixir is too terrifying once the pill is exploded, even he is not sure that he will retreat with his whole body, and the difficulty of fusing the next spirit grass spirit material is too great, and he must let go when it is time to let go.
