This time, he found spring bamboo shoots in a bamboo forest not far from the lake. The spring bamboo shoots here are not big, only two or three catties in size, but the taste is quite delicious. What's even more rare is that these spring bamboo shoots have reached the rank of secular middle grade, which makes Tian Xu very satisfied.

He searched for this small bamboo forest and dug up a total of more than a dozen spring bamboo shoots. The medicine king bucket has its own preservation function, which will not harden due to the long time of digging, and can be stored for a long time. However, Tian Xu still boiled about half of the spring bamboo shoots in water and then drained the water to make dried bamboo shoots, the taste of dried bamboo shoots is different from that of fresh bamboo shoots, in comparison, Tian Xu prefers the taste and texture of dried bamboo shoots.

In addition, there is a relatively small bamboo, which also produces bamboo shoots. This kind of bamboo shoot is only two or three centimeters thick, the body is slender, the taste is more tender, but the grade is not as high as those bamboo shoots, only barely reaching the worldly lower grade, and the number is not much, he only found a few dozen in total.

After playing with this qi, several days had passed, and both of them felt that their realm had been stabilized, so they began to meditate and cultivate. Ziyan was honestly sitting and practicing, while Tian Xu was busy with other things.

It turned out that Ziyan had been pestering Tian Xu to help her find a way to dive underwater alone. Now Ziyan has only just reached the ninth order of qi gathering, and he can't condense the formation of underwater breathing at all, so how can he realize the ability to breathe underwater alone? However, Tian Xu thought of a feasible way, that is, to make a formation for Ziyan to breathe underwater, and the function of breathing can be realized by infusing the breathing formation into it.

Speaking of formation weapons, Tian Xu had only come into contact with some superficial knowledge when he was discussing with Fang Jing and Qu Wenfang in Xiduotang last time, but he was no stranger to formations, and this time, under the entanglement of Ziyan, he wanted to try to get a set of formation weapons by himself.

During the test, he first used the jade talisman he asked for from Qu Wenfang. This thing is inexpensive, and I don't feel bad when I use it.

Speaking of which, there are many similarities between the formation and the runes, but the cultivation world divides them into two fields, this is because most of the methods of making formation weapons and runes that have been circulating in the world are mature methods that have been circulated for many years, and the so-called formation mages and rune masters in the cultivation world have only learned specific production methods from the masters, and they only know them but do not know why, and it is more difficult to make innovative improvements.

In addition, ordinary array masters or talisman masters are even rarer than alchemists in the cultivation world, they can often rely on ancestral techniques to live an enviable and wealthy life in the cultivation world, and there is no shortage of various cultivation resources and social status, of course, they will not easily pass on their skills, and there is no channel of communication between the two, which is also a reason why the level of refining array weapons and talismans in the cultivation world is getting lower and lower.

Like Tian Xu, those who dare to try to make their own talismans or formations are often regarded as beyond their means, not to mention that expensive array weapons or talisman raw materials are even more prohibitive.

For a period of time, Tian Xu has been pondering the method of refining talismans, and he already has some ideas. When he was in Kitatang, he followed Qu Wenfang to study and make the Berserk Danhuo Talisman, after all, he had a lot of contact, and he secretly learned a lot about this talisman. At this time, he took out the spirit jade rune blank he bought from Qu Wenfang, imagining the formation that needed to be used, and the method of carving on the spirit jade.

To put it bluntly, this talisman is still the application of the formation, when he was studying alchemy, he had worked a lot on the formation, and he already had a certain foundation, and at this time it was used in the study of the talisman, which reduced a lot of workload for him.

The formations that Tian Xu usually uses are all condensed with aura, and they require his continuous control to maintain their existence. And this talisman is to depict the formation onto the spirit jade talisman blank, so that it can exist independently from its own control. It is equivalent to sealing the formation in the spirit jade, and when it needs to be used, it only needs to input a necessary activation signal to activate the relevant formation and release the sealed moves or specific formations inside.

Tian Xu had the experience of carving formations on the pills, although most of those formations were automatically generated by the Dan furnace, but they were used too much, especially when refining the pills that were not in the Dan furnace, he still needed to personally build the formation and depict it on the pills. If you have done a lot of this kind of thing, you will have the experience of carving the formation on a certain basis, and it will be much easier to try to refine the talisman at this time.

Tian Xu's research was still fruitful, and after half a day, the first talisman blank was made. He didn't have a special array for the infusion talisman, and he couldn't make it for a while, so he had to rely on his familiarity with the spell that was about to be infused, and forcibly condensed a few formations to temporarily control and use it. It takes a lot of effort, but there is no other way to solve the problem temporarily.

The first talisman that Tian Xu was ready to pour was an ordinary Danhuo talisman, which was relatively simple, and the continuous Danhuo could be compressed and sealed at a relatively slow speed, and the requirements for operation were not high.

Tian Xu condensed a small ball of Danhuo, then fixed and compressed it, extracted the aura and formation of Danhuo, compressed it into a solid state similar to Ning Dan, and then fixed it with the formation engraved in the Lingyu rune blank, and completed the infusion of the first experimental Danhuo talisman.

After the infusion was completed, Tian Xu withdrew the auxiliary formation, and there was no obvious change in the spirit jade rune blank, and there seemed to be no problem. He scanned this made talisman with his divine sense, and found that there was a ball of spiritual energy that had been compressed to the extreme in the spirit jade, which was not significantly different from the talisman infused by Qu Wenfang, and there seemed to be no problem.

He carefully picked up the jade talisman and after checking it repeatedly, he decided to try it out. However, he was still a little uneasy, and let Ziyan wait on the hillside, while he himself flew into the air in the middle of the lake and crushed this piece of rune jade.

With a "poof", a pure aura emanated from the rune jade and slowly dissipated in the air, while the long-awaited Danhuo did not appear at all, and the experiment failed.

Tian Xu returned to the hillside with a depressed expression. Ziyan comforted: "It's okay, the first experiment, if it doesn't fail, it's not normal, just take your time." Why don't you take a break and get something to eat?"

"Okay. Hearing Ziyan mention the matter of eating, he remembered that he hadn't eaten for several days. It doesn't matter if he doesn't eat by himself, but Ziyan's realm is low, and he will still be hungry if he doesn't eat for a long time.
