"Linyuan?"

"Yes!"

Lei Huangding asked Su Fei to take out Lin Yuan and explained carefully: "With the level of that refiner, the artifacts cast are definitely four or five grades higher, and the reason why Lin Yuan is only a second grade is because Lin Yuan did not satisfy his tone after becoming an embryo, so the refining stopped here." ”

"Are you saying that Lin Yuan is an unfinished semi-finished product?"

"Of course. ”

Lei Huangding said something serious: "Take yourself as an example, you can still refine the Dragon Snake Body Forging Body Paste now, but your current Dan Dao level is already comparable to that of a sixth-grade alchemist, will you still focus on this kind of gadget? ”

Su Fei nodded, it was indeed impossible for this non-lethal refining master to spend energy just to cast an eight-grade sword, it was estimated that after the embryo shaping was completed, he felt that it was not enough to continue the next step of refining, so he didn't even continue to depict the Locking Spirit Array.

But now there's another problem.

The lock spirit must be carved as soon as the embryo is formed, because the spirituality will be lost over time, and now it has long disappeared, and even if it is portrayed, there is no spirituality at all.

Lei Huangding knew what he was thinking when he saw Su Fei's frowning appearance, and sneered: "I said that your brain is usually good, why are you so stupid! ”

"Damn, I really forgot about this!"

............

The next day, the refining factory.

"Master Su Fei, this is the Spirit Infusion. Song Yi led Su Fei to a closed factory, which was already a little dilapidated due to disrepair, but the equipment was well preserved, and someone came to maintain it every week.

This equipment was originally only used by an old refiner, but he had been transferred elsewhere, and now even Lu Qizhuang would not use this thing.

Therefore, when they heard that Su Fei was going to inject spirits, all the refiners stopped their work and ran to Su Fei's side to observe, and a large area was full of 1 under the monitoring screen

Su Fei asked, "Let's have spirit stones in our refining factory, give me a little even, and I can pay for it." ”

Spirit stone is a consumable material that must be used for soul infusion, and the price is extremely high, and ordinary people don't even know about his existence.

However, Su Fei learned from Tian Yanzi's memory that this spirit stone was actually a kind of hard currency, and after the cultivation gradually increased, ordinary currency had lost its utility, and those masters traded with each other basically with spirit stones or barter.

Each spirit stone will have a professional organization to determine the spiritual power content in it, and show the relevant certificates, and will also mark the spirit stone with a unique numbering code, and it is a strategic resource, which needs to be approved by the state.

There are not many spirit stones in the warehouse, and they are still left from before. Song Yi took out three spirit stones and handed them to Su Fei. Don't look at the spirit stone, which is only the size of a fingernail, but one piece costs more than 10 million!

In the expectation of many refiners, Su Fei put on a protective suit and rushed into the closed factory.

The door of the factory closed, and a group of refiners couldn't help but start chattering about it.

"You say, can Master Su succeed this time?"

"I feel that it can be done, you look at Master Su's face, and I almost wrote the words "easy as a palm" on my face!"

"But I still feel bottomless, this is a spirit infusion! How can it be so easy, if you don't understand it, you have to explode, this embryo body explosion is not good, but it will kill people!"

It's no wonder that these refiners are so nervous, under normal circumstances, if the refiners find that there is a problem with the refiner, even if they can use the spirit to remedy it, they will not hesitate to forget about this choice.

Because the difficulty of infusion is too great, it is better to refine a new one!

It is precisely because it is too difficult to infusion that there is even a niche profession among refiners, that is, professional infusionists.

These infusions are also the most elite part of the refiners, and almost all of them are high-grade refiners. Because only extremely precious objects will be repaired by them with infusions, ordinary objects are not worth their hands on at all.

Therefore, with the increase of the grade of the soul infusion master, the treatment of the soul master also rises in a straight line, and even the treatment of the alchemist under the same level is half a step higher!

Every refiner was staring intently at the monitoring screen as Su Fei had already appeared in the screen.

The infusion is quite dangerous, so the factory that holds the infusion equipment is also sealed layer by layer, and even the outside is reinforced with alloy steel plates.

Su Fei was observing the spirit infusion equipment in front of him.

This infusion device is composed of two parts, the infusion device occupies two-thirds of the entire equipment, and the other third is the inscription device that inscribes the Soul Locking Array.

The infusion device is composed of two parts, the lower part is the base of the fixed sample, which can be switched to adapt to the appearance of different models of the device, and the upper part is a robotic arm structure, which is less than dense with precision electronic components, and there is a white transparent pipe inside that is connected to a sealed structure at the rear.

This sealed circular structure is the place where the spirit stone is stored, and the spiritual power in the spirit stone will be extracted in the sealed circular structure by a special process, and injected into the end of the mechanical arm with the transparent pipe.

There's something like a welding torch there, and it's up to it to engrave the Locking Array.

This kind of thing is an absolute foundation for a seven-grade refiner, and it is extremely precious, just like Lu Qizhuang, he will only have one kind of locking spirit array, and this is only one type of seven-grade magic weapon of any form.

But Su Fei was different, because his "Hundred Explanations of Refining Weapon Basics" recorded no less than dozens of methods for depicting the Locking Spirit Array, and each shape of magic weapon was also different in adaptation to the Locking Spirit Array, but the low-level refiners didn't pay attention to these.

Su Fei carefully studied Lin Yuan last night, and finally found a kind of Soul Locking Array called "Plum Blossom Branding" in the "Hundred Explanations of Refining Weapon Basics".

The Linyuan Sword was taken out and placed in the sample tray to fix it back and forth, and as the equipment slowly operated, the transparent pipe began to slowly turn white from one end, and the tip of the electronic pen at the end of the robotic arm became brighter and brighter.

The mechanical arm slowly probed down under Su Fei's control, first hitting the tip of the Linyuan Sword, and at the moment of the point, Su Fei felt that something was slowly flowing into the Linyuan Sword.

The most difficult thing is to ensure the uniformity and smoothness of the infusion process, because the energy contained in the spiritual power is quite high, which is not comparable to ordinary energy at all.

Once the uneven injection of the front and back of the ritual instrument can easily lead to irreversible changes in the embryonic body, and then various accidents will occur.

This kind of spiritual operation is purely technical, and the current mechanical accuracy can not be controlled by the input code in the CNC computer, and can only be manual.

Su Fei held the joystick with both hands and remotely controlled the mechanical arm to move back and forth on Linyuan, but it seemed to be irregular, occasionally as fast as lightning, and occasionally as slow as a turtle, making Song Yi confused from the outside.

The reason why this is so is because the premise of the infusion is that the refiner must have perfect control over the structure of the entire embryo body, and judge the speed required by the infusion based on the structure and feel, which is a craft work and the most difficult part of the infusion.

"Whew-"

Two hours later, the spirit was complete, and the feeling of satiety made Su Fei breathe a long sigh of relief.

At the moment of successful infusion, Su Fei suddenly felt that he had an inexplicable connection with Lin Yuan, and Lin Yuan seemed to come to life, conveying a feeling similar to joy to Su Fei, and there was even a trace of gratitude mixed in it.

This is the most different place between the seven-grade magic weapon and the ordinary mortal weapon, with the injection of spiritual power, the magic weapon will have a soul, otherwise it is just a body, no different from a mortal weapon.

For a while, Su Fei's spirits were greatly lifted!

Outside the factory, a group of refiners also cheered.

"It's done, Master Su is done!"

"I didn't understand anything, but I'm still excited, haha!"

"After I go back, I will study and study it carefully, but unfortunately I don't know Master Su's on-the-spot operation methods, hey, I can't learn this thing just by looking at it. ”

"It's good to be able to see it, why don't you go to heaven if you ask so much!"

Song Yi and Lu Qizhuang were also full of excitement, especially Song Yi, who had even thought about the strategy of the factory in the future.

Lu Qizhuang even dragged Song Yi hard: "Old Song, you have to hurry up, sign Master Su while no one knows now, and in the future, if we want to inject spirits, we can hand it over to Master Su!"

"That's what I thought, too. Song Yi nodded emphatically.

The inscription of the Locking Spirit Array was also started immediately, and the inscription process could still be carried out manually, but Su Fei had already entered the code into the CNC computer in advance in order to speed up the progress, after all, every loss of spiritual power was an irreparable loss to himself.

There are no flashes of electric sparks like electric welding, and no noise of mechanical cutting. The end of the mechanical arm moved silently on the sword, but it took only five minutes to complete the carving of the Locking Spirit Array.

When the portrayal was completed, Lin Yuan also threw a burst of joy at Su Fei, which made Su Fei couldn't help laughing: "It's done!

Driven by Su Fei's emotions, the Linyuan Sword also let out a sword roar, like cold water gurgling through a clear spiritual spring, which made Su Fei's mind clear.

Su Fei subconsciously beckoned, and the Linyuan Sword instantly broke free from the originally fixed buckle and flew into Su Fei's hand after trembling twice.

"Haha, it's really done, my seven-grade magic weapon!" Su Fei stretched out his hand to hold the hilt of the Linyuan sword, but before he was happy, he suddenly felt a strong sense of exhaustion hit his heart, and the pitch black in front of him fell to the ground.

............

"Oops, my head hurts......"

Su Fei opened his eyes and found himself lying on the sofa in Song Yi's office, with a large group of refiners next to him.

Seeing Su Fei wake up, they flocked to Su Fei one by one, chattering and asking.

"Don't speak, I'll ask!" Song Yi shouted, and the surrounding voices gradually died down.

Song Yi said: "Master Su, your cultivation is only in the realm, how did I just see you stretch out your hand and your sword flew up!

The eyes of every refiner are full of curiosity and doubt, the seven-grade magic weapon can only be used by the powerhouses of the Kaiyuan Realm, this is the common sense on the rivers and lakes, and ordinary people can't even do the step of recognizing the master.

But Su Fei did it!
