Zhu Youdao searched the treasury of the Great Holy Valley, and he was a little reluctant to go, so he left the practice of refining weapons on weekdays, as well as some magic weapons of poor quality, in the warehouse, and piled up the cave again, from the appearance, there were some signs of a treasure house.

For the monkeys, the original things are useless, but these magic weapons can be used. Sun Wudao was a little reluctant to see it, so he gave Zhu Youdao a few jars of monkey wine.

Zhu Youdao took Li Yunniang to search for the spiritual grass and spiritual objects around the Great Holy Valley, until the storage bag could not be filled, and then he reluctantly returned to Zhujiazhuang.

After arriving home, Zhu Youdao thought about it for a while, he had no time to be distracted, Xie Xiaohong and Zhu Youqing were a little reckless in their personalities, and they were not suitable for alchemy, so after thinking about it again, they gave Li Yunniang the jade slip of alchemy inheritance and asked her to learn alchemy.

Li Yunniang has a characteristic, except that she has no spiritual root, her cultivation progress is slow, and she can learn almost everything as soon as she learns it.

Zhu Youdao didn't want her to be distracted and affect her cultivation, but there was no one in the Zhu family available, and alchemy was too important, so she could only cultivate at the same time. Fortunately, alchemy has a direct effect on improving cultivation, if Li Yunniang relies on her own cultivation, there is no hope in this life, and learning alchemy may not be a way out.

Zhu Youdao said to Li Yunniang: "You first figure out some alchemy, and I'll go and refine an alchemy furnace for you." In addition, this time in the Great Holy Valley harvest is abundant, there are a lot of spirit grasses that you can't use up for the time being, these spirit grasses will soon die if there are no special storage tools, I have to refine some jade boxes and jade bottles to store spirit grass first. I won't be able to use it in the future!"

Li Yunniang nodded, took the jade slip and went to figure out the alchemy.

Zhu Youdao raised the fire and took out a white jade seal, which was the jade seal of the Zhenguo of Yue back then.

The royal family of Yue is the descendant of the Yuwen family of the Xiuzhen family, after getting the relics of the Yuwen family, Zhu Youdao once inquired, this Yuwen family was a hundred years ago, and it was also a famous family, although there was no Jindan monk, there were five foundation building masters at the same time in the heyday, and it was almost the same as the six alliances of the mirror lake island.

But the Yuwen family didn't know what mysterious forces they had offended, and they were wiped out overnight, and no one in the family survived.

Zhu Youdao was afraid of getting into trouble, so he didn't dare to investigate the affairs of the Yuwen family in depth, and only inquired about these superficial information.

The Yuwen family had five Zhuji back then, and it could be regarded as the overlord of the small family.

Therefore, when the Yuwen family established the Wu Kingdom, they were rich and rich, and the jade seal used was carved from the spiritual jade of the cultivation realm. This spirit jade is widely used in making storage tools. For example, jade boxes, jade bottles, etc., are used to store spiritual herbs and pills, etc., which can prevent the loss of vitality and aura and store them for a long time.

Zhu Youdao is now going to refine the Zhenguo jade seal into a jade box, which will be used to store the spiritual grass collected from the surrounding areas of the Great Holy Valley.

Zhu Youdao's talent in alchemy is good, and at this time he has been able to refine first-order high-grade magic weapons, but refining the jade box is different from others, and the mustard seed sigil must be engraved in the jade box to increase the space inside the jade box.

The difficulty of depicting the mustard seed sigil is relatively high, Zhu Youdao has been trying to refine the storage bag in the past year, and the biggest difficulty is the mustard seed sigil, with a success rate of less than three percent.

Zhu Youdao's spirit jade materials were limited, so he was extremely cautious in refining.

Three days later, Zhu Youdao came out of the refining room.

He had used up enough materials for three jade boxes to get one, but he was already satisfied.

After transferring the fresh spiritual grass obtained from the Great Holy Valley to the jade box, Zhu Youdao repaired for two days, opened the furnace again, and began refining the alchemy furnace.

The refining furnace that Zhu Youdao bought from Sanxiu in Vientiane City back then had long been eliminated, and now he uses a new product that he has refined himself, and the quality is as high as the first-order top grade. For the sake of this satisfactory work, he wasted more than 30 materials. In terms of value, this refining furnace is a big loss, but in the long run, it is still worth it. First of all, Zhu Youdao's refining furnace is refined according to his heart, which is more convenient to use, and the success rate when refining magic weapons will increase a lot; secondly, after more than 30 attempts, Zhu Youdao has added a lot of experience in refining Ding furnace magic weapons, which can not be bought by many spirit stones.

With the experience of refining the refining furnace, Zhu Youdao's grasp of the refining furnace has increased a lot.

The appearance of the refining furnace and the alchemy furnace is similar, but the internal structure is very different.

Alchemy pays attention to the control of temperature, the spirit grass is delicate, most of them are afraid of fire, and the temperature should be high and low at any time, and the use of simmering fire.

After half a month and more than a dozen wasted materials, Zhu Youdao was able to refine a satisfactory alchemy furnace.

This Dan furnace uses a fire control sigil to control the temperature as you like, and a Sumeru sigil is used externally, and the furnace body can be large or small. Three-legged and two-eared, carved dragon pattern phoenix, like a work of art, is Zhu Youdao based on the art modeling on the Internet in his previous life.

Li Yunniang couldn't put it down after getting it, which made Xie Xiaohong and Zhu Youqing eccentric.

At this time, Li Yunniang had already figured out alchemy, and the difference was the actual operation.

Zhu Youdao gave her all the alchemy materials and let her practice by herself.

Then Zhu Youdao plunged into the refining room again and began to refine the engraving of the first-order high-grade spirit rune.

Since the second order of the spirit rune, the talisman material and difficulty have been greatly improved, each spirit rune is unique, and the possibility of using engraving talisman is greatly reduced, therefore, the first-order high-grade spirit rune is the main product of maximizing the benefits of engraving talisman.

After Zhu Youdao gave Sun Wudao a stick magic weapon, its original weapon stick was discarded casually. The monkey head is not cherished, but Zhu Youdao regards it as a treasure.

After taking it back and carefully identifying it, it was confirmed that this stick was a first-order high-grade dragon claw locust trunk. The dragon claw locust grows slowly, only one inch in diameter every 100 years, and this stick is five or six inches thick, and it is already five or six hundred years old.

Another three months have passed, and in addition to his daily cultivation, Zhu Youdao spends some time every day to practice the Flying Knife of the Retreat, and the rest of the time is used to refine talisman carvings.

There are many types of first-order high-grade spirit runes, and Zhu Youdao chose the types of spirit runes with relatively large sales to refine, and successively refined the engraving plates of spirit runes such as ice runes, flame explosion runes, vajra runes, magic runes, and hidden runes.

After refining this batch of engravings, Zhu Youdao's mana surged, a warmth rose, and his cultivation was successfully promoted to the fifth level of qi training.

Zhu Youdao was not shocked in his heart, as early as when he concentrated on refining the formation banner of the Mountain Protection Array, he felt the signs of promotion, and it was not until this large-scale refining of magic weapons that he was able to break through.

The four arts of the Dan Weapon Talisman Array are the first of the hundred arts of cultivation, and in addition to their relatively large effects, they are also very helpful for cultivation. Zhu Youdao has been refining magic weapons on a large scale twice in a row, consuming a lot of mana every day, which is also a kind of tempering for mana, making mana more refined and manipulative more freely.
