At the spiritual object exchange office, after exchanging twenty copies of materials, Mu Ziyan found a tree hole with no one and began today's practice.

There are four kinds of materials for refining Tianyuan Grass, namely: a one-star demon crystal with a wood attribute, a crystal stone, a ten-year-old ginseng, and a bottle of essence blood of a one-star high-level demon beast.

Take out all the ingredients, including the pots, and arrange them in front of you.

Qi turned into a dantian, and the spirit medium slowly floated out, and with Mu Ziyan's control, the runes in the spirit medium began to transform continuously. Although the mother talisman of Tianyuan Grass is a little more complicated than that of Juli Grass, it is still at the simple level, and Mu Ziyan does not have much effort to convert.

It only took more than ten minutes for a new rune to appear in front of him, this was the mother talisman of Tianyuan Grass.

When the mother talisman in the spirit medium was fully formed, Mu Ziyan controlled the demon crystal to fuse with it, hum! After the two merged, a dazzling aura lit up on the surface of the demon crystal, which meant that the mother talisman had been successfully made.

After that, the combination of the demon crystal and the basin was also very smooth, but this time three whisker-like spiritual threads grew at the bottom of the demon crystal, one more than the giant grass.

Mu Ziyan waved his hand, and one of the spiritual threads was wrapped around a ginseng plant, and it began to 'spin into a cocoon'. With the rapid surge of the spirit thread, soon a thin layer of silk thread was wrapped around its surface, and the outline of the sub-symbol was already on the surface of the silk thread.

However, Mu Ziyan frowned slightly, and found that something was wrong. This spiritual thread is derived from Mu Ziyan's spiritual power, and because the volume of ginseng is larger than other materials, the spiritual thread required to wrap it will be much more than before, if you continue to give birth to spiritual threads, it will lead to insufficient remaining spiritual power, and it will be difficult to complete the following steps.

Mu Ziyan only paused slightly, and immediately increased the spawning of the spirit line, it has already arrived, no matter what happens in the future, at least you can't give up here, at most you will lose some materials.

As the spirit thread continued to be entangled, a huge cocoon soon appeared at the end of the spirit thread, and the surface of the cocoon had a shiny rune, apparently this sub-rune was successfully made.

After that, a second thread wrapped around the crystal, and unsurprisingly, another cocoon with glowing runes appeared at its end.

At this time, a little sweat had already appeared on Mu Ziyan's forehead, obviously caused by excessive spiritual power consumption, but he did not hesitate and immediately started the production of the third sub-talisman.

The production of all the child runes must be done in one go, with only a slight pause in between, but not too long, otherwise it will cause the connection between the child and mother runes to be abnormal, so that the refining of the treasure medicine will fail.

Click, the jade bottle containing the blood of the demon beast was shattered by Mu Ziyan, and then wrapped by the third spiritual thread, this time the speed of winding was very slow, obviously Mu Ziyan had more than enough strength and insufficient strength, and the spiritual power had gradually dried up, and it was difficult to support the next consumption.

But he didn't give up, he was still gritting his teeth and insisting, squeezing every trace of spiritual power left in his body little by little.

One, two, three.....

Compared with the rapid winding of the first two sub-runes, the post-production of this third one is very difficult, Mu Ziyan is already counting the number of circles of the spirit thread winding, and each circle of winding is very difficult, as if it will stop at any time.

Boom!

Seeing that there were still more than a dozen laps left, it was completed, but at this moment, Mu Ziyan's eyes were dark, and the person fainted, and his face made a close contact with the trunk of the tree, making a muffled sound, which seemed to be a good fall. This is a fainting caused by excessive consumption of spiritual power.

Although he tried his best to squeeze every trace of spiritual power in his body, he still failed in the end, and he was only a small step away from success.

"It's just a little bit, it should be successful next time!" Five minutes later, Mu Ziyan woke up weakly and muttered to himself.

And the disk fell to the ground, and all the talismans he had made before were cracked, and by the way, the cracks of the four materials in it, apparently these things were scrapped.

After an hour, Mu Ziyan's spiritual power returned to a full state and continued to start the next refining.

Boom!

There was another muffled sound, Mu Ziyan fainted again, this time compared with the previous refining, the completion progress of the third sub-talisman actually did not advance but retreated, and at least thirty more circles were wrapped around before success, obviously the refining of Tianyuan Grass was not as simple as Mu Ziyan thought.

It seems that the first time he was able to reach that level, it was completely by relying on his amazing willpower to squeeze the spiritual power in his body to barely reach that step, and the second time he refined, there was not so much hidden spiritual power in his body for him to squeeze, this was the reason why he did not advance but retreated, and this result is the best proof.

After recovering again, it was another attempt.

Boom!

Keep trying.

Boom!

…..

When Mu Ziyan fainted because of exhaustion and couldn't remember how many times it was, finally in the summary of his continuous efforts and failures, the sub-talisman on the third cocoon was lit up, which meant that he was finally able to refine the treasure medicine of the three sub-talismans.

Hurry up and recover, although the remaining steps are not as hard as when building sub-symbols, but they are meticulous work, and they are the result of starting all over again if there is a slight mistake, and there is no room for a little sloppiness.

The production of the child and mother talisman is just a threshold, as long as the cultivation is enough, plus a good spiritual control, it takes some time, and it can be completed theoretically. The latter refining part is where the talent of the tree refiner is distinguished, only a true genius can quickly master this complex energy conversion and successfully refine the treasure medicine.

An hour later, Mu Ziyan was resurrected in a full state again.

Mu Ziyan looked at his masterpiece in front of him, his face was full of smiles, every time he progressed, it meant that he was one step closer to becoming a powerhouse, and at this time, it was the happiest moment of all his cultivation time.

Coax!

However, with an explosion, the smile on Mu Ziyan's face disappeared, followed by anger, to be honest, Mu Ziyan himself didn't know, he hadn't shown an angry expression for a long time, even if he provoked him like Shan Qingwen before, he was too lazy to care, but the situation in front of him really made him angry.

I saw that the tree hole where he was was was pierced by a sharp weapon, of course this is not the key, the most hateful thing is that this sharp weapon destroyed the treasure medicine that Mu Ziyan was refining while passing through the tree hole.

One of the three spiritual threads connected to the child talisman was severed by this sharp weapon. After the sub-rune that lost the connection of the spirit line fell, it turned into fragments with a snap, and the remaining two sub-runes and the demon crystal on the disk were all shattered in the next few seconds.

Mu Ziyan waved his hand, put everything away, and the fist full of spiritual power bombarded the wall of the tree hole, and with a bang, the whole tree fell in response.

At this time, he was angry to the extreme, and if he didn't beat up the culprit who caused this reason, it would be really difficult to eliminate the hatred of his head.

You know, after wasting so many materials, tired of dying and living, it was hard to succeed once, but it was ruined by someone like this, and it's hard to say whether it can succeed next time.

"Don't run."

Mu Ziyan, who broke out of the tree, quickly found the target. The cultivation place he chose was originally located in the middle of nowhere, and few people usually came, and there was only a figure in front of him that was about to disappear into the distance, and he didn't have to think about it to know who did it.

The afterimage flashed under his feet, and Mu Ziyan used his body martial arts to chase after him as fast as he could, and compared to the figure in front of him, his speed was more than twice as fast.
