The secret room is underground. Qingyang followed them through a secret Road, and then went deep into the ground dozens of feet along the steps before finally arriving. This is the forbidden area of Mo family. Only the owner can use it. This time, I came here because the refined things are too valuable.

In the middle of the chamber of secrets is a huge array. In the center of the array, large pieces of pyrotechnics are placed according to certain rules. On the ground flint, a cluster of flames with a large bowl mouth are burning. The flame is completely different from the common fire. The color is red like blood. Just looking at it from a distance, Qingyang feels the heat is pressing and seems to be sweating.

Seeing that Qingyang was interested in the fire in the middle, Mo Rong took the initiative to introduce: "this fire is called the extreme fire in the center of the earth. It only exists in the depths of the center of the earth. It was obtained by an ancestor of the Mo family who spent a lot of energy in the late foundation building hundreds of years ago. In order to ensure that the extreme fire in the center of the earth does not go out, our Mo family spends a lot of spirit stones to purchase ground fire stones every year to maintain the operation of the array."

Now Qingyang was more curious and said, "what's the use of extreme fire in the center of the earth?"

Mo calcined: "the fire provided by the earth core extreme fire is higher than the flame temperature of the spiritual material. Even it is not much worse than the Dan fire of the golden pill friar. Moreover, the earth fire flame temperature is constant, which is easier to control, and it is very helpful for refining tools. To tell the truth, if the Mo family did not have this earth core extreme fire, I would not be fully sure of refining the best spiritual tools."

Whether it's Alchemy or device refining, the requirements for fire are very high. Ordinary fire can't meet the requirements. High level friars can use Dan fire, but the consumption of Dan fire is too strong. Anyone can't stand it for a long time.

In addition, the more common one is ground fire, and the other is spiritual fire generated by spiritual material combustion. It is troublesome to control the fire of spiritual material combustion, which will affect the effect of refining device. Ground fire is easy to use, but Kyushu has few land or resources, so it is rare in peacetime.

Unexpectedly, the Mo family managed to get such a cluster of ground fire, but the ground fire so obtained belongs to the rootless source, and the price is relatively high. The Mo family needs to buy a large number of ground fire stones every year to maintain it, which consumes a lot.

Qingyang feels that if he also has such a cluster of extreme fire in the center of the earth, his success rate of alchemy can be improved a lot. Not to mention 10% and a half%, there are still three or five points. It doesn't seem to be many, but for some pills, three or five points are the key to success or failure.

If you have a chance, you can also try this method. At least when refining those high-level pills, you will be more confident and not easy to make mistakes. After a long time, the materials saved are also considerable.

Just when Qingyang was thinking, the Mo brothers over there had come to the extreme fire in the center of the earth, put the things prepared in advance, and then opened the array in front of him.

Several ground fire stones were added to the array. The extreme fire in the center of the earth was more prosperous than before. When all the preparations were arranged properly, Qingyang handed Mo calcine the snake skin in the golden elixir period. Then Mo calcine sat next to the ground fire and began to deal with the snake skin in his hand through the extreme fire in the center of the earth. Mo Rong was not idle. He took out the auxiliary materials they prepared one by one and treated them according to certain requirements.

Qingyang is idle and has nothing to do. He watches. The Mo brothers don't deliberately hide from Qingyang. They don't seem to be afraid of Qingyang's stealing.

When refining spirit armor, Mo is mainly in operation, but in some key places, Mo will also ask Mo Rong for help. It seems that there is a tacit understanding between brothers and there has been no problem.

Qingyang found that the refining device was similar to alchemy. All materials were pretreated according to certain steps, and then added to the main materials one by one. When all materials are refined into one, they are refined and formed according to certain regulations.

However, it is not so simple to refine the materials into spiritual objects. It also needs to describe the array and strengthen the function. It can't be completed without certain strength and experience. In short, no matter what he does, he needs this talent. Qingyang's talent is in alchemy. It's difficult for him to refine this weapon even if he follows an expert closely.

The two weapon refiners couldn't disturb. Qingyang lost interest after watching it for some time, so he found a quiet corner in the secret room to meditate and practice.

Unknowingly, more than two months have passed, and the refining of Lingjia is coming to an end. The Mo brothers are haggard because of their long-time operation, and the wrinkles on their faces are deeper than before. Obviously, it can be seen that their minds are overdrawn.

Like alchemy, refining utensils not only consumes real yuan, but also a great test for the monk's mind. Most people can't stand not sleeping for more than two months. Fortunately, the spirit armor is about to take shape, and there is not much work left. Just stick to it a little. At this time, Qingyang also had no intention to practice. He sat far away in the corner of the secret room and quietly watched them operate.

Mo rongduan sat next to the ground fire. His upper clothes had long been left aside. He was naked and covered with sweat. He controlled a spirit armor with his mind and kept rolling on the ground fire. At the same time, he would make a slight adjustment to the match method according to the fire situation and the needs of the spirit armor.

The Mo calcine beside him was also disheveled and sweaty. Half of his body leaned forward and almost fell into the ground fire. His hands kept carving on the spirit armor. He could see that the scattered light in the air was converging towards the spirit armor. From his slightly nervous expression, it can be seen that the refining of spirit armor has reached the most critical moment, and there can be no loss.

Looking at this scene in front of him, Qingyang could not help sighing. As expected, it is as separated as a mountain. It is not so easy to learn this refining tool. The cooperation between the two people is so troublesome. I'm afraid it would be more difficult for one person to refine spirit armor. Compared with this, alchemy seems to be easier.

At this time, I suddenly heard Mo calcine shout: "the array has been portrayed and will start to melt the spirit soon. Second brother, get ready and don't make mistakes."

"Elder brother, just do it, there will be no problem on my side," Mo Rong replied.

Then both sides moved at the same time. The spirit armor in the ground fire suddenly shook, and the nearby spirit Qi gathered towards the spirit armor, and the spirit light on the spirit armor became more and more prosperous, just as the peerless treasure was about to be born. It looked very dazzling.

I don't know how long it took. Suddenly, the light and shadow of a spotted green snake appeared in the air, which was somewhat similar to the appearance of the green waist. The snake shadow hissed up to the sky, and soon hid into the spirit armor below. The dazzling Spirit Light dissipated in an instant, revealing the true face of the spirit armor.
