In the following days, long Bufan went to work in the beast control room every morning to earn some contribution from the sect. In the afternoon, he hardened his head and continued to learn the rune array with elder Xu. Although he was angry on the surface, long Bufan had a stubborn heart. Since he chose, he must learn it well.

    So day after day, in the twinkling of an eye, three months later, his cultivation in all aspects increased significantly, and his animal control skill has been able to control level 3 Warcraft. Of course, his own cultivation has also declined, and he has been promoted from the early stage of Kaiyuan to the later stage of Kaiyuan.

    That afternoon, long Bufan didn''t go to Cuilin pavilion to find elder Xu, but went to the alchemy workshop to forge 50 bullets, which was enough to exchange 300 zongmen contribution points, and the silver of gunpowder almost used up his savings in recent months. But as a life-saving weapon, the cost of these things can not be saved.

    "Bankrupt again." when he walked out of the alchemy workshop, long Bufan shook his head and sighed in his heart. It would be good if he were a rich second generation. At least, don''t worry about having no money to refine lethal weapons such as sniper guns and Gatling machine guns.

    At the moment, the situation of long Bufan is a little similar to that of a skillful woman. It''s difficult to make bricks without rice. She has no intention to make it.

    Back in the dormitory, long Bufan secretly locked himself in the bedroom, put more than 50 bullets and May 4th pistols on the table, then took out a small cloth bag from his arms and poured it out.

    A small black and gold carving knife, a bottle of precious Huoyang grass juice, and a piece of array Rune paper. These three things are insignificant, and their value can almost buy a medium-sized building.

    The sharp end of the carving knife is suitable for carving small array patterns on the surface of bullets. The juice of Huoyang grass is the energy to enhance the power of the array. Long Bufan borrowed it from the cabinet when he practiced at elder Xu yesterday.

    That array Rune paper was an isolated array that long Bufan rightfully asked elder Xu for. Once it was opened, any movement in the array could not be heard by the outside world.

    Because the rune master''s initial experience is accumulated by burning materials, long Bufan can''t afford to burn. He must ensure that he can successfully draw a complete Rune array every time.

    He held the carving knife in his hand and practiced it on an iron plate for thousands of times before he finally began to formally operate the materials. Long Bufan picked up a bullet, concentrated, poured yuan force into the carving knife, and carefully traced and engraved the tip on the warhead.

    The carving knife is worthy of being made of black gold. It is hard and sharp. There is no resistance in the depiction. It took about half a cup of tea to complete. Looking at the past, the whole array has beautiful and symmetrical lines, with a flowing beauty.

    Soon, long Bufan poured out a drop of Huoyang grass juice, and his five fingers gently pinched a printing formula. A yuan force entered into the drop of juice, and then pulled the liquid fused with Yuan force to condense into runes, engrave them into warheads, and re integrate with that array.

    With the flash of light, the array pattern was hidden inside the bullet, and the surface was still as smooth as new.

    "Oh yeah, that''s it." long Bufan stood up excitedly and smiled at the corners of his mouth. The array just described is the fire attack array ''explosion flame array''. If a bullet hits, the array will automatically open and produce a flame that burst like a volcano.

    "Let''s experiment."

    Long Bufan muttered. First, he picked up the array symbol paper and Yuan Li entered it. The array diagram in the paper burst into light in an instant, enveloping the whole bedroom and completely isolating it from the outside world.
