Nine poles of Douluo

Regarding the research on the core formation of the Spirit Gathering Array, Lin Bufan already has a certain clue.In fact, the soul guide itself has a core formation similar to the spirit gathering array, called the energy gathering array, but this energy gathering array can only be used to charge soul power, and what Lin Bufan wants to study is to gather the energy of heaven and earth. The spirit gathering array is not the energy gathering array.

Generally speaking, the principles of energy gathering array and spirit gathering array are not much different.Lin Bufan had a thorough understanding of the principles of the energy gathering array during this period of study, and he planned to transform it on the basis of the energy gathering array.

However, this transformation may take a long time. Lin Bufan plans to build a rough formation pattern in a month or so, and then test and correct it one by one.

The next day, Lin Bufan was studying the Spirit Gathering Array in his dormitory. He kept sketching lines in his mind, and then drew these lines one by one on the paper.

Soon, a 1x1 meter wide paper was filled with various complex patterns. This was the core formation of the Spirit Gathering Array designed by Lin Bufan himself, and the center of this core formation was blank. This is the position of the formation eye, and a piece of heavenly material and earthly treasure needs to be used to suppress it.

Next, it requires constant testing and correction.

Lin Bufan looked at the formation drawing with satisfaction and put it away. The level of the core formation of this spirit gathering array has now reached level three, which is exactly the highest level that Lin Bufan can currently draw.

Just as Lin Bufan put away the drawings of the Spirit Gathering Array, there was a sudden loud knock on the door.

"Boom!"

Lin Bufan frowned slightly and released his mental power. Through the barrier of the wall and door, he saw the person knocking on the door.

It was Orange. At this time, Orange had an anxious look on his face and kept knocking on the door of Lin Bufan's dormitory.

"Lin Bufan, are you there?" Orange shouted while knocking on the door.

Lin Bufan slowly withdrew his mental power, then walked over and opened the door.

"What's wrong?" Lin Bufan looked at Orange's anxious look and asked in confusion.

"Something happened to Huo Yuhao." Orange said: "He had a fight with one of our senior brothers, and now he was caught by the Royal Pickets."

Orange said, her face still a little hot, because she was the cause of what happened at that time, and Huo Yuhao's arrest now has something to do with her.

"Okay, I understand." Lin Bufan said calmly: "Don't worry, he will be fine."

Orange looked at Lin Bufan in astonishment and said, "Are you not worried at all?"

Lin Bufan looked at Orange strangely, "Why should I worry?"

Huo Yuhao is the protagonist of this world, and he has the aura of a protagonist. It would be strange if something happened to him.

"If there is nothing else, I will continue to be busy." Lin Bufan said. He has almost finished his research. What is left is that he needs to try and correct his mistakes again and again. He has no time to care about Huo Yuhao. Although Du Weilun came to him before coming back and asked him to help Huo Yuhao as much as possible, with Huo Yuhao's aura as the protagonist, nothing would happen at all, and there was no need for him to get involved. He might as well be busy with his own affairs.

Orange took a deep look at Lin Bufan and said coldly: "Since you don't want to help, then I have to find a solution myself."

Orange's voice was cold. She didn't expect that Lin Bufan would be such a person. Even if something happened to her companions, she wouldn't follow them to find a solution.

"Yes." Lin Bufan nodded calmly, then closed the door and continued his research.

Orange looked at Lin Bufan closing the door, his expression became even colder, he took a deep look at Lin Bufan's dormitory door, turned around and left.

……

Lin Bufan took his drawing and first went to the Second Laboratory to find his mentor Tian Shude.

When Tian Shude learned that Lin Bufan came to him to ask for some rare metals for experiments, he was slightly surprised and at the same time relieved.

Finally, he took out some rare metals and handed them to Lin Bufan, patted him on the shoulder and said, "Although it is important for young people to learn knowledge, they must also remember to relax and rest appropriately."

"I understand, thank you, instructor." Lin Bufan thanked him politely, and then returned to the dormitory with these rare metals.

The rare metals Tian Shude handed over to Lin Bufan were relatively common and easy to obtain.

After getting the things, Lin Bufan first cut the metal into the shape he wanted, a circle, and then began to carve the core formation on it.

Lin Bufan was a master at cutting. His carving knife was a small silver carving knife, about half a foot long. In Lin Bufan's hand, complex lines quickly took shape in his hand.

After carving for almost an hour, with the completion of the last line of carving, the core formation was finally carved.

Lin Bufan used his soul power to brush away the metal debris on the core formation, and then rested for a while. Carving the core formation was the most labor-intensive. Even though Lin Bufan's mental power was very strong, he felt a little tired. .

After resting for about a quarter of an hour, Lin Bufan picked up the core formation, injected soul power into it, and started testing.

"Om-"

Visible to the naked eye, starting from the outermost periphery, the lines of the core formation lit up one after another, and then moved towards the center.

However, just when these lines reached halfway, they suddenly stopped, as if they encountered some obstacle, and did not move forward any further.

When Lin Bufan saw this, he immediately canceled the injection of soul power. He knew that he had failed.

Only half of this core formation is usable, or it may not be usable, because he is not sure whether the usable part of this core formation is really usable, but now the soul power can flow unimpeded, as long as can be proven correct.

Lin Bufan rubbed his eyebrows. This core formation must continue to be improved.Immediately, Lin Bufan pulled himself together and took out the drawing with the original core formation, and then began to make improvements on it.

The core formation can be regarded as the core of a soul tool. Just like the soul master, the core formation is also divided into auxiliary core formation, offensive core formation and defensive core formation.

The core formation of the Spirit Gathering Array he wants to make is an auxiliary core formation. The auxiliary core formation is much more difficult than the offensive and defensive core formations.

Lin Bufan rubbed the center of his eyebrows. The key point of the Spirit Gathering Array, the Spirit Gathering Array, is the word "Gathering Spirits". The vitality of heaven and earth must be gathered together. This can be considered a qualified formation.

"Looks like I need to find some information."
