Seeing that Yu Cheng Mo still had no improvement, the stubborn old man sighed and first fused the liquid metal ball and the Zhuxie Sword. Even when Yu Cheng Mo was still not done with it, he could only see if he could just wrap the thin wires around it to make a hand guard rope.

Because they have been melted together, we can no longer try to separate the filaments from other metals. This is the law of refining tools.

He looked back at Yu Cheng Mo still fiddling with the spiritual energy. The stubborn old man slowly began to shape. This process can be taken slowly, but he can't stop.

Bloom! Finally, a little flame appeared in the center of the spiritual energy group, and then slowly expanded, as if the spiritual energy was ignited.

The flames are as orange as ordinary small flames, which are quite similar to the fire disasters encountered when passing through the tribulation.

Looking at the little flame that looked like a candlelight, Yu Chengmo suddenly had a glimmer of enlightenment. No wonder he tried for a long time but failed. It turned out that he was going in the wrong direction.

Tribulation spells are essentially different from ordinary spells. Common spells are composed of spiritual energy. Even if they are fire, they are essentially composed of spiritual energy.

The spells that are understood during the tribulation, such as splitting the sky, are a kind of spell of root cause and qualitative change. They do not need to learn how to form spiritual energy. Even people like Yu Chengmo who have no talent for immortal arts can understand them as usual.

To put it more abstractly, you can use this kind of magic by just having a thought and giving a certain amount of spiritual energy.

The flame in front of me was not composed of spiritual energy, but Yu Chengmo hoped that it would burn, so the spiritual energy was ignited. The flame appeared with spiritual energy as fuel, which was fundamentally different from the fire spell that was essentially composed of spiritual energy.

It’s like one is to use a wooden stick as a weapon to hit the opponent, and the other is to directly ignite the wooden stick and burn the opponent with flames.

"Heaven Tribulation Lihuo!" It was a small flame as small as a candlelight, which also released amazing heat. The stubborn old man who noticed the change turned around and exclaimed: "Have you passed the tribulation?" The celestial tribulation Lihuo is the second tribulation of the ninth level of tribulation. The flame of the fire tribulation. Cultivators who have a deep understanding of flames can understand it in the process of passing the tribulation. The three strange flames used by the stubborn old man are just ordinary fire in front of this kind of flame.

"Boy, come and be a weapon refiner! With this flame, you must have a future!" The stubborn old man shouted excitedly.

"What's the point? Can this fire be used? Can it be thrown away directly?" Yu Chengmo urged with a bad look on his face.

Use a wooden stick as a hit weapon. The wooden stick can be used for a long time or can be held in your hand. However, if the wooden stick is lit, the wooden stick will be continuously consumed. Yu Chengmo's current spiritual energy is slowly decreasing, approaching the red line of the realm.

Moreover, Yu Chengmo was not sure if he could use these tribulation spells as usual if he fell to the fusion stage.

"Just throw it away directly, if possible, it's a little bigger." said the stubborn old man.

Yu Chengmo added a handful of spiritual energy and threw the flames down, then fed the spiritual energy into it little by little.

It’s like watching the chef at home cook cooking when he was a child. It was a technical job. If you add less fire, you will get more fire and make more fire, and the rice will be burnt.

Fortunately, I have the experience of the stubborn old man. After watching for a while, I could see the relationship between spiritual energy and flame strength, and directed Yu Chengmo to increase and decrease spiritual energy.

Under the heat of the heavenly tribulation, the light golden metal wires finally began to melt, turning into golden liquid and melting into the sword of Zhuxie, which seemed harmonious and clear.

This is a necessary link in the formation of spiritual tools, so that all materials can form a whole, with harmonious and unified breath, and then separate them to form various parts.
