All the steps had already been deduced countless times in his heart, and Chen Pan no longer wasted time, and directly took out the small copper furnace and began to refine the metal.

Pure titanium is not the refining material Chen Pan wants, what he needs is titanium alloy. Titanium alloy is formed by mixing titanium with a variety of other metals, and the different proportions will inevitably lead to different properties of titanium alloys.

Although Chen Pan still remembers the composition of titanium alloy, it has no effect on the specific composition ratio. In this way, Chen Pan spent nearly half a month refining hundreds of titanium alloys in different proportions, and then selected the one with the highest hardness. The strength of the metal is generally not a big problem, and the hardness is the key.

In the middle, Uncle Gangzheng came to see Chen Pan once, and thought that the performance of the small copper furnace used by Chen Pan was too poor, so he didn't know where to find a small black furnace and gave it to Chen Pan.

The performance of the small black furnace is obviously more than one grade higher than that of the small copper furnace, and what makes Chen Pan even more excited is that there is actually a space magic circle in the small black furnace, which can automatically compress the refined metal liquid, which saves Chen Pan a big trouble, otherwise he really doesn't know how to use to hold those refined metal liquids.

Chen Pan removed the "Yuan Qi Breathing Sutra" and only practiced two exercises: the Thousand Gods and Ten Thousand Senses Technique and the Millisecond Observation Technique. Chen Pan didn't know how effective these two exercises were, but when they were used to refine weapons, Chen Pan quickly realized the magic.

The Thousand Divine Consciousness Technique can keep one's mental power strong for a long time, and the Millisecond Observation Technique is not simple. There is not just one metal in the ore, but many other things in it. If you become a cultivator whose strength is determined, you will naturally have a way to get rid of the excess substance, but if you are a person like Chen Pan who is at the bottom of the cultivation world, it will be a big problem.

Now with the millisecond observation technique, Chen Pan only needs to mentally lock the atom he wants in the ore, and he can refine this substance through the small black furnace, while other things do not move at all, and the purity can almost be 100%. This is difficult to do under the highly developed level of science and technology in the previous life, but now he can easily do it, which can't help but make Chen Pan sigh at the magic of cultivating immortals.

Putting the small black furnace on the ground, Chen Pan kept putting the ore into the refining, and then threw away the slag. The surrounding "mines" have basically bottomed out, and they have all been refined into the small black furnace by Chen Pan. Chen Pan, who did not have great magical powers, could only move the ore into the small black furnace piece by piece, and such repetitive work had lasted for several months. If it weren't for the Thousand Divine Consciousness Technique, it is estimated that he would have fainted to the ground due to mental exhaustion.

Although this small black furnace was not much bigger than a palm, and the liquid in it was only the size of two fists, it actually already had a mass of several hundred tons, and Chen Pan couldn't hold it up at all, so he could only put it on the ground of Jinshi Peak. Fortunately, Jin Shifeng was protected by a formation, and the ground was extremely hard, otherwise this pressure would definitely easily press Jin Shifeng out of a hole.

After successfully refining the last piece of ore required, Chen Pan took a long breath and threw out the slag, and the refining work was finally completed. The Little Black Furnace was definitely the best metal refining equipment in the previous life, and in the millisecond observation technique, the various metal liquids inside were combined together in a very perfect atomic lattice.

Controlling the metal liquid in the small black furnace into a bell shape, Chen Pan took a deep breath and began to carve the formation. This time, Chen Pan no longer uses an iron pen, but uses mental power to portray. The iron pen engraving formation method is a method used by beginners in the Eight Classics of the Orthodox and is intended to be practiced. The spiritual power portrayal formation can completely integrate the formation and the magic weapon, which is the method that a refiner should use.

When making a bronze bell, Chen Pan was able to use spiritual power to depict the formation, but he was not skilled at that time, so he didn't use it. After nearly a year of training, Chen Pan has already been able to skillfully use this method of using spiritual power to depict formations. Now that it is true to refine a defensive magic weapon, Chen Pan naturally wants to use this good method.

The first bronze bell, because of the excitement, turned out to forget that many formations were not engraved, and became a pure gadget that could only be used for viewing. This time, Chen Pan learned a lesson, and the formation needed had already been thought of.

The first one must be able to refine, so the control formation must not be missing.

The second one must be able to be big and small, and the contraction formation cannot be less.

The third one should be harder, and the strong formation must also be engraved.

The fourth one should be able to be used in the air, and the flight formation should be engraved quickly.

。。。。。。

It took three days for Chen Pan to engrave all the formations he expected into the body of the bell, and then used some connecting formations to skillfully fuse all the formations together, so that they would not repel each other. If someone else does it, it will be absolutely difficult, and this requires a very thorough calculation of the role and order of all formations in advance. But for Chen Pan, who was an excellent physicist in his previous life, these are all easy, and he must learn mathematics well before learning physics, and being proficient in arithmetic is a necessary ability for a physicist.

After all the formations were carved, Chen Pan felt that this was already the most perfect state he could do, and the next step was to refine.

There are various methods of refining, water refining, thunder refining, fire refining... However, more than ninety percent of cultivators use fire to refine this method, and only a very few special magic weapons will consider other methods. Chen Pan was naturally no exception, not to mention that his strength was already low, and fire refining was the best and easiest method for him.

When refining with fire, the level of fire is very important, and the higher the level, the higher the performance and success rate of the fire refining magic weapon. For today's crucial step, Chen Pan spent some time studying the fire formation when he was in the library, and he was finally able to depict the fire robbery formation that could only be used by Yuan Infant Stage monks. This may still be a low-level flame for others, but for Chen Pan, it has finally changed qualitatively.

He used his pitiful true qi to give birth to the Fire Tribulation Formation, guiding the flames into the small black furnace. In the raging flames, the formation began to slowly merge into the bell. It's just that there are too many formations, and Chen Pan's strength is too poor, and the whole process lasted a week to complete. Chen Pan, who was seriously overdrawn, completely relied on perseverance to persevere.

As the last circle was fully integrated into the body of the bell, it was finally completed, and a small dark golden bell in the small black furnace slowly floated up. "Hum!" A bell rang, and Chen Pan felt that his soul resonated with it.

I don't know if it's an illusion, Chen Pan actually felt that this bell had an illusion of flesh and blood connection with himself. To be precise, this dark golden bell is like a child born to him.

His grandmother raised bears, how did Lao Tzu give birth to children, hell. Chen Pan cursed secretly, and then his face changed greatly, and he didn't know when a black cloud appeared in the sky above Jin Shifeng.

Heavenly Tribulation, it's impossible! Chen Pan panicked suddenly.
