Li Feng, vice president of the Southern Branch, received a letter from the inspection, and for the first time knew that there was such a thing as bail, as long as he handed over 50 million lower grade spirit crystals, Di Qing could be released from prison on bail; however, it was stipulated that Di Qing could not leave Vermilion Bird City, and he must be guarded by Hao Yun, if Di Qing escaped from Vermilion Bird City, not only would 50 million lower grade spirit crystals be confiscated, but also the case handed over to the supervision brigade this time was directly determined to be committed by Di Qing, and the arrest document was taken over by the law enforcement brigade.

As soon as Li Feng saw the word Hao Yun, he understood that this idea should be Hao Yun's idea, and after thinking about it carefully for a while, he immediately followed up to discuss. After getting the approval of the upper echelons, Li Feng came to the inspection branch, swiped his card to pay 50 million bail, took Di Qing out of the prison, and returned to the station of the Southern Branch with Hao Yun by the way.

After the reward notice of the traveling merchant surnamed Zheng was issued, there was no follow-up. As a result, not long after Di Qing went out, the patrol received news that someone said that there was a whereabouts of the traveling merchant surnamed Zheng, and the patrol hurriedly sent a group of people to arrest him.

Di Qing and Hao Yun looked at the ground fire under the forging table, the flame had maintained a good strength and intensity, and the fire shone on the two people's bodies, and they fell into silence for a while.

After a long time, Hao Yun asked, "What kind of spiritual weapon were you and Lao Yi building that day?"

Di Qing didn't reply directly, but turned his face sideways, looked at Hao Yun in surprise, and then looked at the earth fire carefully, and then said, "What did you do to this earth fire?

"Hehe, I didn't expect President Di to be able to feel that this earth fire has spirituality, could it be that the secret of earth fire is this?" Hao Yun was full of spring breeze, and his smile was overflowing.

"No, no, no. Shouldn't this be the case? If the junior brother can make the earth fire lose its spirituality, then wouldn't it mean that the junior brother is comparable to the god of fire. Di Qing muttered as he carefully observed the forging table.

After careful inspection, Di Qing's face changed, and he shouted at Hao Yun: "Senior brother is a bit excessive, deliberately set up a trick to hide the real earth fire, just to trick my words." ”

"Hehe, President Di has been thinking too much, I already know the secret of the earth fire, I can go into more detail, this earth fire has divine sense. Hao Yun was full of confidence and broke through.

"It seems that everyone still underestimates the junior brother, I have been investigating here for several years, and it is better for the junior brother to come for two or three days. Di Qing looked lonely.

"Senior Brother Di, although I can guess the secret of the earth fire, but I can't crack it, and Senior Brother is about to crack it, this is what makes me admire. Hao Yun immediately became humble, and Hao Yun empathized with Di Qing's persistence for several years. As some geniuses, they can achieve success quickly, but for most people, it takes a long and boring research process to get the results at the end. For most systems in the spiritual world, they are not created by geniuses, and the systems created by geniuses may only apply to geniuses. Just like the exercises researched by the Gongfa Research Institute, they need to go through a lot of improvements before they can benefit most people.

"Where can I talk about cracking, I can only say that I have some experience. As soon as Di Qing said this, Hao Yun felt that there was a play, and it seemed that the problem was in this experience.

"I don't know if Senior Brother Di's experience has been revealed to the outside world?" Hao Yun asked, Di Qing frowned and thought about it.

"I didn't share that I had learned from the outside world, or even with anyone else in the club. Di Qing replied affirmatively.

"That's it!" Hao Yun also pondered, and suddenly an idea came to mind, "Senior Brother Di did not make any moves before this?" and this move aroused the suspicion of others. ”

"I needed a piece of Mithril before that, and I asked my secretary, Miss Ho, to help me buy it. I wonder if it will have something to do with this matter?" Di Qing, under Hao Yun's guidance, was already suspicious.

"If Senior Brother Di doesn't mind, can you talk to me about this Mithril, what kind of key role does Mithril play here?"

After a long ideological struggle, Di Qing decided to tell everything. In fact, it is very simple, after the Instrumentalists Federation discovered this place, they became interested in the earth fire here, and before Di Qing, they also successively sent several presidents of the Southern Branch to be responsible for the study of the earth fire, but the progress was very slow. Due to the lack of true fire-based cultivators in the spirit world, most people don't even have the possibility of touching the earth fire with their divine sense, and they don't even have a door to study it in depth. Until Di Qing was born, Di Qing, as a rare genius of the Federation of Instrumentaries, was particularly good at the research and creation of new things, and had a high reputation in the Federation. So the Instrumentaturists Federation sent Di Qing to the Southern Branch as the president, hoping that he could study the secret of the earth fire and promote it, so that it would definitely be a great opportunity for the Instrumenters Federation to develop and take off.

Di Qing really lived up to his trust, and after becoming the president of the Southern Branch, Di Qing had a lot of novel ideas for the study of earth fire, at least in terms of methods. In short, he is helpless compared to others, he not only has a method, but also has a small gain. It can be said that during Di Qing's days in the Southern Branch, the high-level leaders of the Instrumentaincy Federation were very satisfied, and it was even rumored that once Di Qing cracked the secret of the earthfire, he was likely to become the next president of the Instrumentalist Federation.

Di Qing himself has indeed thought of a lot of ways to study the earth fire, Di Qing is not a fire cultivator, his research is not through his own divine sense, he uses the method of creating spiritual weapons to study the earth fire. According to some existing metal materials, he used these metal materials to create the same kind of spiritual weapon, and then tested the obtained spiritual weapon, after layers of screening, he found that gold and silver, a precious metal material, is the most suitable for the earth fire, compared to other materials, in the process of building, the earth fire can play the best state. After continuing his research, Di Qing finally locked on Mithril. Mithril is not the most valuable metal material in the spirit world, but it is definitely the most difficult metal material to find. Since Mithril is generally encased in other metals, it is difficult to find a single Mithril Mine to mine. It can only be said that when other metal deposits are mined, some discoveries may be made. As a result, it is difficult to find large pieces of Mithril, which are basically small pieces one by one. Although it is a small piece, it will not affect the use, because Mithril is generally used as an additive, for example, when creating a flying sword, the main body may be made of fine iron, but after adding a little Mithril, a special alloy is formed, which changes the characteristics of fine iron and makes it play a stronger performance.

This kind of small piece of Mithril has troubled Di Qing for a long time, because Di Qing has an idea, this idea is to use the whole piece of Mithril to create a spiritual weapon, so there is a big requirement for this piece of Mithril, too small pieces are not applicable, and the applicable ones cannot be found. Until one day, Lao Yi said, he found a piece. Di Qing saw that it was indeed the right size, so he intended to buy it from Lao Yi, who knew that Lao Yi said that he didn't want money, but he just hoped that when Di Qing built the spirit weapon, he could watch from the sidelines. Di Qing also hesitated, but finally agreed to Lao Yi's request, Di Qing had been tormented by ideas for a long time, and when he got this whole piece of Mithril, he began to build it as soon as possible. Who knows, as soon as he started building, he was inspected and broke in, and not only was Mithril confiscated, but even he himself was imprisoned.

Hao Yun didn't understand that Di Qing had to use a whole piece of Mithril. Di Qing explained that due to the differences in the characteristics of each piece of Mithril, if you have to mix it together, the effect will be relatively poor, which is different from mixing with other metals to form an alloy state, and different Mithril is not completely compatible with each other, even if it is fused together, it is just that you have me, I have you, and the Mithril block formed has different characteristics, which is very unusual, but it makes the quality of Mithril decrease.

Hao Yun then asked Di Qing, what do you think of Lao Yi, the instrumentalist? Di Qing thought for a long time, and said slowly: "Lao Yi is also the first batch of instrumentalists to join the Southern Branch, he was there when I didn't come, it stands to reason that he should have no problem, and he himself is also locked up in prison, unless he doesn't even want his own life." ”

"At that time, you asked Miss He to make purchases, how did this news reach Lao Yi's ears?" Hao Yun did not catch Lao Yi, but changed the question.

"Because this kind of large piece of Mithril is rare to find, I asked Miss He at that time to find a way to start with the firm that provided the materials, because they had a better chance of encountering it. It is estimated that in this way, Miss He will start with the instrumentalists who cooperate with major commercial houses. Di Qing analyzed.

If so, Miss He passed the news to Lao Yi, if Lao Yi was not lying, this Feng family should also get this news, but Lao Yi said that this piece of Mithril was his own, not provided by the Feng family. It seems that Lao Yi has concealed a lot of key issues, and it seems that I have to go to the prison to interrogate him. Hao Yun speculated according to Di Qing's statement, and found more and more that the labor was very problematic.

Di Qing stood up and asked to go with Hao Yun to inspect the branch, he tasted it carefully, and found that Lao Yi did have a major suspicion, but he couldn't figure it out, why Lao Yi just deduced from a piece of Mithril that Di Qing had a major breakthrough in Earth Fire, and set up such a killing situation, in order to kill Di Qing, he even sacrificed himself.

The two brothers of the Dong family were chatting in the office, when suddenly there was a knock on the door, and an inspector walked in, saying Hao Yun, Di Qing and Li Feng, and the three of them were back.

Dong Shi muttered: "What kind of gourds are these three people selling? After walking for a while, they really treat our inspection branch as a vegetable market." ”

"Brother Dong, I'm really embarrassed, there has always been a sentence that I don't know whether to ask or not?" Hao Yun walked in alone and saluted the two brothers of the Dong family.

"Brother Hao is too polite, he speaks when he has something. Dong Shi hurriedly returned the salute and replied.
