When the world finally calmed down, Mu Ziyan entered the secret room alone and began refining the treasure medicine for the first time in his life.

Today, his goal is the 'Juli Grass', which is the easiest to refine of all the treasure medicines. As the name suggests, it can be seen from its name that the giant power grass can increase the strength of the person taking it by about 20% in a short period of time, but don't underestimate the increased power, in the battle, any external force may become the key to victory or defeat.

To refine the treasure medicine, you must first prepare a 'basin', and it is better to call it a plate than a basin. The basin is a circular shape on the outside, with a transparent hole in the center, a diameter of between 20 and 100 centimeters, a round thing of different sizes, and a large number of arrays are carved on the surface of the basin, which looks very mysterious.

In general, the quality of a pot is directly proportional to its size, and the larger the pot, the better.

The basin can be said to be a necessary thing when refining treasure medicine. It is a necessary carrier to connect the medium and the spiritual object, plus to carry the treasure medicine. It's like a plant grows in soil, even if seeds and fertilizers are readily available, if there is no soil for them to grow, the seed will always be a seed and will never sprout and grow.

Of course, there are good and bad pots. You think, although sand and soil can make plants grow, but under the same environment and the same fertilizer, the plants in the soil will definitely grow much stronger, and this cannot be changed.

And Mu Ziyan's basin is only twenty-three centimeters in diameter, which is the lowest one, after all, it is a crime to be guilty, and in the absence of strength, being rich is a disaster. So his mother Wang Su'er only prepared an ordinary basin for him, but for now, this basin is completely sufficient.

There are three kinds of spiritual objects needed to refine Juli Grass: a bottle of essence blood of a one-star intermediate demon beast, a sober leaf, and a one-star demon crystal with an earth attribute. The sober leaf has been exchanged back yesterday, and it is not expensive, it is the same as the one-star demon crystal, it is worth a hundred spirit points, and the other two things are kept in yesterday's harvest.

Since the success rate of refining the treasure medicine was very low, he prepared a total of more than a dozen materials.

In fact, the refining process is simple and clear, that is, it is similar to the child and mother array in the spirit array. The process is to convert the energy in the sub-array into the mother array, and then the mother array is in a special way, with the spirit medium, to transform it into another form of existence, so as to achieve a qualitative change in energy.

It's just that they are connected not by formations, but by special runes.

After taking out the basin, Mu Ziyan first sank into the dantian, and the spirit medium slowly floated out under its urging, and then he controlled the control runes in the spirit medium to constantly change shapes, and soon, the control runes were transformed into another kind of runes, but compared with before, the new runes looked much more simplified. This is the mother rune in the rune of Juli Grass.

Among all the treasure medicines, this mother talisman can be said to be the simplest, so it is relatively easy to convert, if the level of the refined treasure medicine exceeds three stars, the complexity of its runes will make ordinary people dizzy just by looking at it, let alone making it.

When the production was completed, Mu Ziyan made a move with his right hand, and a one-star demon crystal appeared in his hand, and under his control, the spirit medium leaned towards the demon crystal.

Originally, the spirit medium was a diamond-shaped crystal, and the demon crystal was also a crystal, and it was logically impossible to merge into one, but what was unexpected was that the two were like stones entering the water, and the spirit medium penetrated the shell of the demon crystal without resistance and entered it.

When the two merged, the demon crystal suddenly had a bright light, and under the illumination of its light, the entire secret room was as bright as day.

The appearance of the light proves that Mu Ziyan's mother talisman has been successfully made this time, if the production fails, although the spirit medium can also enter the demon crystal, but the light will not appear, then it must be made from scratch, and this means that this demon crystal is scrapped.

When the demon crystal was put into the hole in the center of the basin, its light disappeared instantly, and the array on the surface of the basin was instantly lit up, and the whole basin looked like a beautiful handicraft, flawless and pleasing to the eye.

By now, refining the Great Power Grass had entered the most difficult step. These are just the sowing stages of planting, which are the simplest of all the steps before harvesting, and the care and fertilization required for the next growth are the key.

At this time, the basin slowly floated in mid-air, and then under the urging of Mu Ziyan, on the side of the basin facing the ground, that is, the bottom of the demon crystal, two whisker-like transparent colored spiritual threads slowly grew, and the spiritual threads swayed left and right in the air, fluctuating, to the point that there was a bit of a supernatural feeling.

At this moment, Mu Ziyan waved his arm, and a clear green leaf and a jade bottle appeared below the spirit line.

After that, Mu Ziyan controlled one of the spiritual threads to wrap around the blade, and soon a ball-like thing appeared, and at the same time as it was wrapped, a rune was actually formed on the surface.

Although the whole process didn't take much time, Mu Ziyan's forehead was already covered with fine beads of sweat, obviously this was not as simple as it seemed.

When the rune is constructed, the entire leaf is completely wrapped in the spirit thread, like a cocoon, and when the spirit thread stops wrapping, the formed rune begins to glow as if it has been smeared with phosphor.

This cocoon-like thing with strange runes is the child of the rune of the child.

Call!

"Finally got one." Mu Ziyan breathed a sigh of relief for the time being.

These two spiritual threads are the bridge of communication between the child and mother runes, and all the energy in the child runes is transmitted through this spiritual thread. Only after the construction of the child rune is successful, relying on the connection between the child and mother runes, the child rune will be lit, which means the success of this step.

After temporarily pranayama, under Mu Ziyan's control, another spiritual thread wrapped the jade bottle containing the essence blood.

Then Mu Ziyan waved his arm, and a soft spiritual power hit the jade bottle.

Click!

The jade bottle instantly turned into fragments and fell to the ground, and the strange thing was that the essence blood in the bottle seemed to be unaffected by the gravitational pull of the center of the earth, and it was still floating in place, and even the shape was bottle-shaped.

As before, soon, another cocoon with a sub-charm appeared at the end of another thread.

Completing these two sub-runes is already Mu Ziyan's limit, if it is a treasure medicine that needs to make three sub-runes, with Mu Ziyan's current ability, it is impossible to complete it at all, so in the line of tree refiners, high-level tree refiners must have super strength.

After that, Mu Ziyan took a cultivation posture to recover his spiritual power. Now that the runes have been made, even if they are left alone, they will be fine, the most important thing at the moment is to restore the consumed spiritual power, otherwise the subsequent refining will not be completed at all.

…..

After an hour of recovery, Mu Ziyan opened his eyes again, he could feel that his strength had improved a little, and it seemed that his speed would also increase a lot when he cultivated in a tired state.

Shaking his neck from side to side, which was a little stiff due to sitting cross-legged for a long time, he then stretched his body and exhaled a long breath, and the next step was the final step, which must be done in one go, without a slight pause, otherwise it would fail.

Looking at the basin in front of him, Mu Ziyan no longer hesitated, his palms pushed out, and two spiritual powers shot out from his palms, which were continuously injected into the basin.

And after the basin was injected with these two more spiritual powers, the array on its surface became more dazzling, and after that, a strange scene appeared.

I saw a bud emerge at the top of the demon crystal, and the sprout was like a vegetable seedling just unearthed after the rain, tender and fresh, this is the embryo of the treasure medicine, when it completes its growth, that is, when the treasure medicine matures.

The shoots then began to grow and soon grew a knot taller, but slowed down when they reached two centimeters tall.

At this time, Mu Ziyan increased the spiritual power injection in his hand, and at the same time, the two cocoons under the basin also changed.

The original spirit line was transparent, but now starting from the cocoon, the cocoon that wraps the essence blood slowly turns into blood red, it seems that this is the energy in the essence blood, and then this energy begins to move up along the spirit line, all the way to the root of the spirit line; The cocoon wrapped in the waking leaf turned emerald green, and the same energy moved up to the root of the spiritual thread.

With the infusion of these two energies, the shoots that had stopped growing before began to grow rapidly again, and soon became a small grass.

On the surface, this process seems to allow the treasure medicine to grow as long as the energy in the sub-rune is continuously transported, but in fact, the speed of transporting energy is the key, once there is an energy delivery that is fast or slow, it will cause the treasure medicine to die, and this refining will fail.

This is like a balance with counterweights on both sides, the weight on both sides is constantly increasing, and only when the weight is the same, can it continue to maintain balance, and once one side is heavier or lighter, it will tilt.

Under normal circumstances, the success rate of a tree refiner refining a treasure medicine for the first time will not exceed one percent, which means that the first few times refining a treasure medicine will basically fail, and only with the accumulation of experience can the success rate be gradually improved.

Moreover, even if it is an experienced tree refiner, the success rate of refining treasure medicine will not be too high. After all, the speed at which the different energies are transmitted by the sub-talismans is the same, and even if the same treasure medicine is refined thousands of times, it is impossible to fully grasp its rate, and it is an individual who will make mistakes.

When the grass grows to about ten centimeters, the two cocoons with the child charms regain their transparent color again, as if they have been drained of energy.

At this time, the grass no longer grows taller, and begins to grow a leaf at the top, and as the leaves continue to grow, the earthy yellow demon crystal, the color is getting lighter and lighter.

Bang!

When the grass stops growing, the shard turns transparent and then falls as debris. At the same time, the basin lost its light and fell aside.

At this time, all that remained in the air were the spirit medium, the grass connected to its upper end, and the two spiritual threads connected to its lower end.

Under Mu Ziyan's control, the two spirit threads began to shrink continuously into the spirit medium, and with each contraction, some runes would appear on the surface of the grass, until the spirit lines disappeared completely, and the runes had covered the surface of the grass from bottom to top.

It was as if the rune was made up of two spiritual threads.

And the sober leaves and demon beast essence blood wrapped in the spirit thread have disappeared, and they seem to have been completely absorbed.

Call!

Mu Ziyan breathed a sigh of relief, and since then, the giant grass has been successfully refined.

As soon as he beckoned, the spirit medium returned to the dantian, and the runes inside changed back to their original state.

"I didn't expect to be able to refine it once, and I don't know if it's because of this 100,000-year-old spirit embryo or because of my outstanding talent, I can actually have such a high success rate." Packed the Juli grass with the jade bottle, Mu Ziyan said to himself.
