The improvement work of the Maoshan Courtyard in the mortal world was in full swing, but after assigning all the work, Li Rui suddenly found that he was idle again. Even Chu Peiting's newly established Huarui Environmental Protection and Governance Company does not need Li Rui's help.

There was no way, Li Rui had to tell everyone that he had gone to retreat, and then he closed his door and entered the heavenly court.

Back at the No. 9 garbage disposal station, Li Rui habitually went to look at the laurel tree first, felt the attachment of the laurel tree spirit to himself, and then entered the space of Qinglingshui, replaced the gourd that had been filled with Qinglingshui, and finally walked into the gravity compression space, looking at the five spheres that rotated and revolved between each other in the gravity compression space, Li Rui's face appeared with infinite yearning.

The No. 9 garbage disposal station was as calm as ever, and Li Rui didn't know if Gao Mingzhi, the cleaner who came to deliver the garbage, had promoted it for himself. Anyway, so far, Li Rui has not seen a second cleaner who delivers garbage here.

"Since there is no work to do, let's cultivate!" Li Rui walked to the courtyard and sat down on a futon.

However, as soon as Li Rui sank his mind into the dantian, his eyes suddenly opened again, and at the same time, his mind moved, and a feather nearly two meters long with purple-red flames appeared in his hand.

"The ancestor once bought me a sword embryo at the auction and asked me to fuse this fire feather, otherwise this fire feather belongs to the original ecological material that has not yet been sacrificed, and it is not very easy to grasp and control, only after the sacrifice can it be like a finger." Li Rui then took out another sword embryo, and then muttered to himself.

"Sacrificing fire feathers is a means of refining weapons, and I haven't learned it yet. However, with this sword embryo given by the ancestor, there is no need to work too hard. All you need to do is fuse the two of them! Thinking of this, Li Rui no longer hesitated, and directly moved his mind. He threw the fire feather in his hand at the sword embryo, and at the same time, the two fire dragons formed by the Vermilion Bird True Fire and the Sun True Fire also circled around the sword embryo.

The sword embryo is to allow people who don't know how to refine weapons to refine the existence of magic weapons that meet their hearts, so when the fire feather is put into the sword embryo, the entire sword embryo suddenly begins to change, but this change is extremely slow, until the two fire dragons join the sacrifice of the sword embryo, the change of the sword embryo slowly begins to accelerate.

However, after all, Li Rui's strength is still too weak, this sword embryo has no level, but even if the fire feather is not refined. It is infinitely close to the level of an intermediate immortal weapon, but with the strength of Li Ruihua's early stage, he personally smelts a low-level immortal weapon that is infinitely close to an intermediate immortal weapon, but the load on him is still very large.

"Damn, it's hard!" Li Rui didn't expect that the sword embryos were all ready-made, and he only needed to smelt the fire feather and the sword embryo together, which was so laborious.

Of course, Li Rui can also leave him alone, and the sword embryo can also be automatically smelted with the fire feather. But this time will take longer, and this is not what Li Rui wants to see, so at this time, Li Rui directly urged the two fire dragons to speed up the smelting speed with his mind, and held the porcelain bottle in one hand. When the energy in his body is about to be depleted, he will swallow a pill.

The elixir that Li Rui chose to increase his energy was a qi tonifying pill bought from Huatuo Gu Pharmacy, which was a pure Chinese medicine. It is not a refined elixir, it has only one effect. It is to replenish the energy consumed in the body, and the most important point is. This Qi tonifying pill made from pure Chinese medicine does not have any side effects, which is one of the reasons why Li Rui dares to take it boldly.

Li Rui also has a prescription for this kind of qi tonifying pill, he already feels that he has time to configure it more, although the energy replenished by the qi tonifying pill is even less than that of Pei Yuan Dan, but it is expensive in mildness, there are no sequelae, and it is suitable for use in the mortal world.

The entire smelting process lasted three days and three nights, and the Qi Replenishing Pill also consumed two large bottles, but the final result also made Li Rui ecstatic. At this time, although Li Rui was so tired that he looked a little haggard, he was holding a beautiful and unusual long knife very strongly in his hand.

This knife is not a hilt, just the blade is one meter long, the handle is a crested head, the pointed beak is facing inward, and the blade has two wings, like the wings of a bird that has just been about to spread but have not yet fully expanded. The blade is slender and slightly curved, and the tip of the knife is oblique and sharp, with blood grooves. If you don't look at the phoenix head of the handle and the two wings on the knife head, this knife looks very much like a slender Tang knife.

Li Rui threw a qi tonifying pill in his mouth, and then when the energy in his body was almost replenished, he directly swung his knife and slashed forward with all his strength, and suddenly a purple-red, fire-filled big bird suddenly flew out of the long knife, and then a phoenix roared, and a crack more than one meter wide and stretched a hundred meters in front of Li Rui.

"Good knife, when you swing the knife, there is a phoenix screaming, and you will call it a phoenix in the future!" Li Rui couldn't put it down, looked at the long knife in his hand, and then said excitedly.

This knife is infinitely close to an intermediate-level immortal weapon, full of spirituality, and it can fully feel the owner's love for it, especially when Li Rui named it, the knife suddenly chirped again, and the two seal characters of Fengming appeared directly on the blade.

"Okay, I know you're excited now, and there will be a time when you will make meritorious contributions to kill the enemy in the future!" Li Rui played for most of the day, and finally had an idea to put Feng Ming into the dantian for nourishment.

After the Fengming Sword entered the dantian, there was no dispute with the Taomu Sword, after all, the main body of the Fengming Sword was still the fire feather, even if the fire feather had been fused by the sword embryo, its essence still remained the same.

This fusion made Li Rui understand a truth, that is, the importance of mastering one more technology, and during this time, he obviously didn't have anything too important to deal with, so he directly took out all the alchemy inheritance that Tao Hongjing gave him and studied it carefully.

In the past, Li Rui had also studied alchemy, and even refined some pills with his own hands, but at that time in the mortal world, all kinds of materials were very scarce, even if he set up an agricultural planting company in his hometown to specialize in growing traditional Chinese medicine, it could not meet his needs.

In addition, he didn't even have a good Dan furnace, and the alchemy inheritance obtained by Li Rui at that time was not perfect, so he had not seriously studied and comprehended this alchemy skill.

However, since being really included in the door by Tao Hongjing, Li Rui has obtained all the alchemy inheritance of Tao Hongjing, Tao Hongjing's alchemy level is actually above average, worse than those senior alchemists, but the average alchemist is stronger, Li Rui does not want to become a professional alchemist, he learns alchemy just to meet his own needs, so Tao Hongjing's alchemy is enough for him at present.
