Such a price is not bad.

Since the cost is huge, how could Xu Yi be willing to waste time?

Take a elixir and a cool breeze rose from your belly. Take out several large bags of auxiliary materials prepared early and a bucket of blood drawn from yourself. Collect the fragments of Sanyin wood and place them on one side.

Then, he opened another furnace and debugged it to the fire gathering stage. In an instant, a cluster of dark blue flames jumped out and quickly filled the entire furnace mouth.

Xu Yi grabbed a few pieces of Sanyin wood fragments, and put them into the furnace together. Soon, the Sanyin wood and auxiliary materials in the furnace were automatically wound and gathered into a red iron ball the size of a chicken.

Then, Xu Yi extinguished the fire, drew a small amount of blood, poured it onto the iron balls. In an instant, the bright light in the room was filled with colorful mist. Soon, the color of the iron balls became redder and brighter.

After waiting for about a stick of incense, the color of the iron ball did not change anymore. Xu Yi grabbed the iron ball, placed the furnace mouth, and brought out the gathering of fire. He picked up a small forging hammer from the nearby forging stand, and then began to hone.

One hammer, two hammers...

Perceived the full outward appearance, and every contact between the forged hammer and the iron ball was clearly and accurately projected into the depths of his mind. Soon, Xu Yi realized different tremors, which reached dozens of them.

After memorizing the secret book, he already knew that this kind of tremor was a sign of the five elements entanglement and combination. Each combination was different, either in line with the law or against the law.

The essence of exercise is to break up and down, unreasonable combinations, and reasonable combinations are assigned. When the entire blood vessel is less unreasonable combinations, the more reasonable combinations are, the more reasonable combinations are, and the forging device will be completed.

The quality of the blood vessel depends not only on the quality of the material used, but more on the level of the forging device.

When a finished blood vessel has fewer unreasonable combinations, the better the quality of this blood vessel will be. On the contrary, the worse it will be. If there is almost no unreasonable combination, it will reach the extreme, which is the legendary top-quality blood vessel.

However, the way of heaven can reduce the excess and make up for the shortcomings. The best blood vessel is made against the sky, and it is naturally a rare existence.

On the contrary, when an unreasonable combination in a blood vessel even surpasses a reasonable combination, it becomes a waste tool.

So, after a while, Xu Yi trained a waste tool.

At the moment he smashed the ninety-third stroke, the iron balls that had already turned into iron pieces were forged into several pieces.

The failure of exercise did not make Xu Yi feel depressed at all. He had already made sufficient mental preparations for the difficulty of refining the weapon this time.

The reason why not to try all the Sanyin fragments in one trial is to know that they will encounter countless results.

Exercising separately can save time and also save auxiliary materials and blood.

Putting the pieces aside, he started his second trial.

This time I persisted a lot longer than last time, with a total of 134 drop hammers before the iron sheet broke.

Obviously, although the previous exercise failed, it made him make great progress.

The third time, the fourth time...
