Of course, there are many methods for refining tools, and no cultivator can fully understand them all. However, one thing is certain: the difference between superior and inferior refining techniques is like night and day.

When Mi Xiaojing began to try refining tools, he truly realized how difficult it was. The combination of magical techniques and incantations, as well as the consumption of true qi, was something he could only barely manage.

One Thunder Spirit Pattern was enough to consume half of his true qi. Fortunately, he had time to recover. If he was still only in the Qi Refining stage, he probably wouldn’t even be able to complete the enhancement of one Thunder Spirit Pattern due to insufficient true qi, especially in this type of enhancement.

After only one attempt, Mi Xiaojing understood that he was lucky enough to be able to complete one Thunder Spirit Pattern, which meant that as long as he recovered his true qi, he could enhance the second Thunder Spirit Pattern. This way, he could complete the enhancement of one Spirit Pattern, which was a bit arduous, but he didn’t mind.

Mi Xiaojing failed the first Spirit Pattern enhancement attempt, but after recovering his true qi, he tried again. Generally, if one failed three times in enhancing the same Thunder Spirit Pattern, the embryo would be considered a failure. When refining tools, a single failure would slightly decrease the quality of the embryo, two consecutive failures would greatly decrease the quality, and three failures would destroy the embryo.

However, there was a technique to this. For example, if one failed once, they could temporarily abandon that spot and continue to enhance the intact side. On this Thunder Strike Wood embryo, a total of twelve Thunder Spirit Patterns could be enhanced, which meant there were twelve empty spots for enhancement. As long as the second attempt did not fail, the Thunder Spirit Pattern could still be formed.

This technique was reminded to Mi Xiaojing by Wang Weijun, so as soon as he failed once, he immediately changed positions. After much trial and error, Mi Xiaojing finally managed to enhance all twelve Thunder Spirit Patterns, but the quality of the dagger-like magical tool had decreased significantly.

The final step was to activate the twelve Thunder Spirit Patterns and form a Spirit Pattern. This step was not difficult. After practicing a few times, Mi Xiaojing felt confident and placed the dagger-like magical tool on a stone platform.

Three magical techniques and two incantations were not too complicated. Mi Xiaojing cast the magical techniques and simultaneously chanted the incantations.

In that instant, his true qi was completely drained. Mi Xiaojing’s heart raced. If his true qi was not enough, this magical tool would be completely destroyed. Under the enhancement of the magical techniques and incantations, the Thunder Spirit Patterns on the Thunder Strike Wood began to flicker with dazzling lightning, crackling sounds echoed out, and rays of light flashed. The Thunder Spirit Patterns began to merge.

The silver-white delicate patterns began to twist like rivers, gathering together to form a surging river that quickly swept over the entire embryo.Mi Xiaojing struggled to support himself. He didn’t expect to need so much true qi and was caught off guard. At this moment, a strange force flew out from his heart tower, and countless true word characters were inputted into the embryo along with true qi.

This sudden change not only scared Mi Xiaojing, but also scared Wang Weijun. What was happening?

Countless true word characters rushed out like ants and directly imprinted onto the embryo, combining with the thunder spirit pattern to form a spiritual pattern. This spiritual pattern had changed and was no longer the original appearance. The small true word characters were like schools of fish in a river, making the originally rigid spiritual pattern come to life.

“Is this considered refined?”

“I have never seen this before. It’s strange… I don’t know how powerful it is. You can try it.”

Mi Xiaojing smiled bitterly, “I don’t know how to use it…”

Wang Weijun was speechless. He had already refined the magical sword but didn’t know how to use it. His foundation was too weak.

In fact, it wasn’t that Mi Xiaojing had a weak foundation. Strictly speaking, his progress was already terrifying. He had already reached the Great Perfection stage of Qi Refining after transitioning from Evolutionary Immortality to Cultivation in a short amount of time, making him stronger than many cultivators.

The art of sword control was related to incantations. By using incantations to stimulate the spiritual patterns on the magical sword, one could control it. Of course, the art of sword control also had different levels. A good art of sword control could easily manipulate the magical sword with a simple incantation.

As for the spiritual sword, it was different. To reach the level of using a spiritual sword, one generally had to reach the Foundation Establishment stage. By nourishing the spiritual sword with Golden Elixir, one could form a union of heart and sword. At that time, controlling the sword with one’s thoughts was possible, which was the essential difference.

During the Qi Refining and Foundation Establishment stages, any cultivator was unable to achieve this. Even if you had a spiritual sword, you still needed incantations to drive it, and you couldn’t achieve a union of heart and sword at most.

Wang Weijun had no choice. If he wanted to see the effect of this magical tool, he had to teach Mi Xiaojing the art of sword control. Wang Weijun taught him the art of sword control in a muddled way, and even used the method of inheritance.

Wang Weijun was too lazy to teach, so he directly passed on the essence of the technique, which was a superior cultivation method that even the Heart Sect did not have. Whether it was cultivation, alchemy, or refining tools, it was an extraordinary inheritance.

After teaching him the art of sword control, Mi Xiaojing was amazed by the various techniques and incantations. He realized that there was so much to learn just for controlling a sword.

He sat cross-legged to replenish the consumed true qi. Since he was near the spiritual spring, Mi Xiaojing quickly regained his energy. As time passed, the spiritual qi inside the Sword Heart Sect recovered, and with the addition of the spiritual spring in the cave, the spiritual qi here was already very abundant, making it an excellent place for cultivation.

Mi Xiaojing opened his eyes and picked up the magical sword on the stone platform. It was actually a short sword.When the Magical Sword was just refined, it was truly beautiful to the extreme, but now it has become an inconspicuous black dagger, with no distinctive features.

As Mi Xiaojing observed, Wang Weijun was also watching.

“Strange, how did it become so dark? I can’t see anything special about it. Did the refining fail?”

“It didn’t fail, but I don’t understand why it’s like this! We’ll know once we try.”

The addition of the Spirit Script was also the first time Wang Weijun had seen it, and it aroused his curiosity as well.

“Well, I guess we can only give it a try.”

Mi Xiaojing walked towards the outside of the cave.

Luo Bo and Wei Fu were sitting on the kang, while Zhang Ke was sitting on a stool. In front of him was a basket filled with various dried vegetables, cured meats, salted meats, and air-dried chicken and duck. All of these were sent by Lu Yu, but Mu Xiaoyin was nowhere to be seen.
