After that, instructor Wang tacitly agreed to He Lan's request to have his own private weapon refining room during normal classes. After all, even if He Lan goes to the introductory weapon refining class, it will be of little significance to him.

He Lan sat obediently on the chair, waiting for Teacher Wang to sigh and walked out of the refining room. After pulling it to the door, He Lan was the only one left in the room, and the surroundings suddenly became silent.

Then He Lan jumped down cleverly and came to the books next to the refining room to try to find out if he could have inspiration to create a spiritual array diagram of the pistol.

"Some of them have been turned over..." He Lan looked at several columns and found that these were books he had read when he was locked in the library. He chose to jump over to read books he had never seen before. After turning to the books, he thought of possible ideas and then ran to the weapon refining table and began to conduct experiments. After a little excited, the result was still failure and the pain of failure.

Perhaps because of the reason for contacting the private refining room, He Lan was not only not as discouraged as in the classroom after the failure, but instead became more courageous as the battle was fought. This further stimulated his unyielding spirit and he would definitely not give up.

He Lan spent several days in the private refining room of Mentor Wang. For the sake of the pistol, he asked Qingyu, who came to the refining department, to inform the four people in Class 8 that he needed them to ask him for leave from Mentor Han Yan for a few days, and he squatted in the refining room and didn't come out any more.

Every time Mentor Wang gets off get out of class, he comes to his own weapon refining room and can see He Lan on the weapon refining table either writing hard and refining the spiritual array diagram or flipping through books on the bookshelf. When he is serious, he never expects Mentor Wang to enter and exit.

After discovering that Mentor Wang was innocent, He Lan raised his head with a look of innocence, and after saying hello to Mentor Wang, he continued to bow his head and work hard.

Over the past few days, He Lan has almost wasted a lot of spiritual cores in the refining room, and books have filled He Lan. During this period, He Lan made the shell first and tried to match the spiritual cores that can match the pistol.

Therefore, He Lan also erected a sign for testing at the door, but so far, no bullet hole penetrated the sign.

On this day, Mentor Wang returned to the refining room after class again and was surprised to find the sudden extra signs. The first thing he saw was that he discovered the pistol shell placed by He Lan. Even Mentor Wang had never seen such a spiritual treasure before.

"What is this?!" Teacher Wang looked at He Lan in surprise. He knew that He Lan wanted to use his weapon refining room. It turned out that he was studying spiritual treasures, but what surprised Teacher Wang even more was that He Lan was actually refining the spiritual treasures he had never heard of before.

"This is called a gun." He Lan dragged his tired body and looked up at Teacher Wang, grabbed the shell from Teacher Wang, and began to merge in front of Teacher Wang. The spirit core was integrated into the gun shell, and powerful mental power filled the entire refining room.

Then He Lan pulled down the gun box and raised the pistol, aimed at the sign and pulled the trigger. In He Lan's imagination, there should be a powerful sound, and the sign was penetrated by the bullet in the gun shell, but in reality it was still a dull sound, and the bullet inside did not fly out.

"Failed again..." He Lan looked at the intact sign and was so tired that he lay on the refining table. Even the failed spiritual core did not have time to take it off.

Teacher Wang watched the whole process of this experiment. At this moment, there was nothing else in his heart except shock. He finally understood what he was doing in the past few days.

He thought He Lan was refining spiritual treasures, but he never expected that he was creating a new spiritual treasure system, which would have a significant impact on him.

"Are you creating?" Teacher Wang asked in horror.

He knew that this mortal practitioner was extremely talented, but he didn't expect that he had reached the point of creating spiritual treasures. You should know that the spiritual array that could create a brand new spiritual treasure was all famous weapon refining masters in world history.

"It's almost true." He Lan stood up and took out the failed spiritual core. He already had the concept of a gun on earth, but the spirit array diagram of the gun in this world is his thing.

"Master Wang, how do you think the spiritual array diagram drives the spiritual core?" He Lan lay on the table and raised his head, revealing the smell of self-deprecation in his tone. The spiritual core on the table also rolled down beside Teacher Wang.

"The spiritual core is the heart of a spiritual treasure. The spiritual array map is a bridge that can transmit the power of the spiritual core to the spiritual treasure. There is a bridge to guide the direction of the heart, not the spiritual array map to drive the spiritual core." Teacher Wang looked at the spiritual core refined by He Lan and said to himself, "Why are you all refining complex spiritual arrays? Not all spiritual treasures use compound spiritual arrays."

"As a gun, I feel it must be very complicated, and the corresponding spiritual array diagram is definitely difficult." He Lan stood up and answered Teacher Wang's question seriously. He sat on the chair behind him and looked up at Teacher Wang. His humble and kind look made Teacher Wang feel complicated.

No freshman in these years has been raised to the sky. It has been a long time since there was a humble and studious student. In addition, he has a unique talent and loves to refine weapons. It would be great if he was not a mortal practitioner.

Teacher Wang closed his lips tightly, frowned and looked down at He Lan. He was so fond of talent that he continued to try to guide him under inner pressure.

"Some spiritual treasures have complex appearance, but in fact, the spiritual array diagram is surprisingly simple. For example, the shield has more principles to prepare for appearance than other spiritual treasures. However, the spiritual array diagram sometimes only requires simple Wubi, because it only requires defensive spiritual power on the front." Teacher Wang smiled gently and showed He Lan one of his shield spiritual treasures. Sure enough, the spiritual array diagram above was only a few Wubi.

"Actually, your gun may be the same principle. You always pursue complexity. Why not think about how the gun works and re-draw your own bridge from this point of view? Maybe it's really just a few strokes?" Mentor Wang just said his thoughts, and did not expect that this would lead to the future spiritual treasure revolution. The present world of hot weapons is still in the fantasy world in the era of cold weapons.

But now after hearing the advice of Teacher Wang, He Lan began to question why he subconsciously felt that the pistol was complicated. It was indeed because the gun had a high status in his concept, and then there would be a gun that would definitely be high.

If the gun is really as Teacher Wang said, there is a possibility of just a few strokes.

"How does the gun work..." He Lan repeatedly emphasized. He was excited and couldn't wait to take out the raw materials beside him, and refine a spirit core by himself. He no longer used the spirit core of Teacher Wang to conduct experiments.

After being reminded by Teacher Wang, He Lan burst into inspiration. His originally exhausted body now looks like he is restoring his health and keeps a close eye on the raw materials. Under He Lan's strong mental power and techniques, a brand new spiritual core was born.

"The bridge of his own." He Lan murmured to himself. He raised his smile slightly, attached his finger to the spirit core, and began to draw the spiritual array map he thought of.

Teacher Wang was nervously looking at He Lan's drawing of the spiritual array, frowned and felt uneasy. He might have witnessed the birth of a brand new spiritual treasure with his own eyes, looking forward to ignoring him. This is a freshman who doesn't even have a graduation exam.

He watched He Lan just move on the spirit core, as if he was just signing a character on it instead of drawing a geometric spiritual array diagram, and used his mental power to sign a big word He on the spirit core, the surname that belonged to him.

"This is so messy!" Teacher Wang shouted immediately. He had never seen anyone dare to draw his surname into a spiritual array map. This arrogance is simply bold!

"Didn't Mentor Wang say that he should draw his own bridge?" He Lan was very calm when facing the angry Mentor Wang. He raised a gentle smile and fused the spirit core and the pistol shell, explaining it to Mentor Wang while fusing.

"Actually, the single person next to my spiritual array diagram and the uppermost horizontal line have connected the main part of the gun, and the word "mouth" corresponds to the trigger position." He was not just messing around, and there were reasons for messing around. After fusing the spirit core and shell, he raised the pistol in his hand with confidence and pulled the trigger under many expectations.

"Bang!" A violent sound was made from the chamber of the gun, and the bullets fired from the gun successfully penetrated through the sign placed beside the door and were embedded into the wood of the door.
