According to the regulations of the refining course, in order to finally pass the assessment of this course, the student monks need to pass the assessment of each link, and they also need to independently refine a spiritual weapon to come out of the beggar gang leader in another world. Of course, as a reward, the refined artifact belongs to the refiner. Because of this provision, all the student monks attached great importance to the matter of refining this spiritual weapon.

Although the spirit weapon was not so valuable in this star field, for a low-level cultivator, the price of a low-grade spirit weapon was not a small amount.

After several months of study, many students have passed the assessment of all aspects of the refining course, and they are all refining their own spiritual weapons.

Xiao Ling also passed the assessment of all links in these refining classes, and also put his mind on refining spiritual weapons.

During the recess of this day, Xiao Ling came to the material room, a room of more than 200 square meters. Inside, there were a variety of low-level refining materials.

Xiao Ling walked around slowly, his gaze swept over all kinds of coarse ores, beast furs, and spirit bones. There are many kinds of materials stacked in this material room, but most of them are inferior materials. The quality of the materials and the ability to hold the aura are poor. Xiao Ling searched for the materials he wanted to refine the spiritual weapon in his heart, and he couldn't help but shake his head as he walked slowly.

After seeing some spirit trees and strange grasses. Xiao Ling didn't have much hope for the materials he needed. As I was thinking about going to the market to find the materials I needed, my eyes swept over the innermost corner of the materials room. A large black lid was thrown haphazardly on the ground, covered with dust, apparently thrown in a corner and left unnoticed.

Xiao Ling was accustomed to using his divine sense to look at things, but under his divine sense, he faintly felt a little strange aura on this cover. This aura is so faint that it is imperceptible to the naked eye. The lid is the size of a washbasin and is spread on the floor. The space shrouded by it was still blurry under Xiao Ling's divine sense.

"This thing can actually block my consciousness, and it is absolutely extraordinary. Xiao Ling muttered in his heart, and his footsteps unconsciously moved towards the cover.

Walking to the corner of the house, Xiao Ling reached out to blow out the breeze and blew the dust off the cover. After a puff of dust, the lid revealed a black, textured crust surface.

Xiao Ling looked at it intently, and saw that the lines on this black hard shell were dense and irregular, but the lines were deeply depicted, and there was a sense of vicissitudes between the staggered ones.

At this time, a manager in the material room walked over after seeing Xiao Ling kick up dust. said to Xiao Ling: "Little brother, what's the matter, do you fall in love with this 10,000-year-old turtle shell?"

Xiao Ling turned around, nodded and said, "This is a turtle shell?"

The manager is a high-level student, and his cultivation has reached the late stage of out-of-body cultivation, and when he heard this, he said: "This 10,000-year-old turtle shell should also be a treasure, but I still advise my brother not to waste any effort on it." The shell was hard and heavy, making it a good material for heavy assault weapons or defensive shields. But this turtle shell has a characteristic, that is, it can't cross the spirit, and the true yuan can't enter it. In other words, it cannot be used by monks at all. Such a treasure is just a pile of waste. And this turtle shell can't be cut, so I advise my brother to choose other materials!"

Xiao Ling let out an 'oh' when he heard this, and immediately reached out and touched the turtle shell. This turtle shell showed roughness, Xiao Ling's fingers stroked it, and he felt a burst of coldness.

Xiao Ling took advantage of the administrator's inattention, and the fingertip true element flowed out, and a subtle gray true element instantly merged into the turtle shell. Under Xiao Ling's divine sense, after inhaling that trace of gray true element, this turtle shell showed that the halo was brighter, but this small change was not perceptible to the naked eye at all.

Xiao Ling saw that his True Yuan was so easy to integrate into it, and it was not at all that the administrator said that he could not cross into the True Yuan. Immediately, he didn't refute the manager, but stood up and said, "This 10,000-year-old turtle shell is very good, I'll choose it as the main material for me to refine the spirit weapon." ”

Seeing Xiao Ling's insistence, a hint of hunger flashed on his face and said, "Little brother doesn't think about it anymore, everyone can only choose one of the main materials of this spiritual weapon to take away." If you choose it, you can't choose any other material. ”

Xiao Ling nodded and said, "You reminded me more, I thought about it, and I want him." ”

When the manager heard this, he no longer advised: "Since this is the case, then follow me to register!"

Xiao Ling nodded, the storage ring flashed, and the whole turtle shell was included in the bracelet. At the moment when the turtle shell entered the bracelet, Xiao Ling suddenly felt that the weight of the bracelet had increased greatly, and he was also shocked in his heart. It is important to know that the storage bracelet is usually loaded with other items, and it is not felt that there is an increase in weight. This time, when I put this turtle shell in it, I felt that the weight had increased significantly. Xiao Ling was surprised, but he was secretly happy in his heart. The more peculiar it is, the more precious it is, and Xiao Ling understands this very well.

After the manager registered the information of Xiao Ling's selection of the main material with the identity jade slip, Xiao Ling walked out of the material room and walked directly towards the material purification room.

After Xiao Ling walked out of the material room, the manager shook his head at Xiao Ling and said to himself, "Another stubborn person." It is estimated that in a few days, he will definitely come to beg me to change the main material for him. He can't be so cheap then. The manager seemed to have expected that Xiao Ling would return the 10,000-year-old turtle shell, and looked at Xiao Ling's departing back, satisfied with contempt.

The material purification room has equipment for purifying various coarse ores, as well as equipment for cutting various materials. Xiao Ling came to the cutting area, deliberately avoided the eyes and ears of the other student monks, and quietly took out the turtle shell.

Holding the turtle shell in his hand, Xiao Ling felt heavy again for the first time after the knot. revealed the power of the true element, and only then did he grasp the turtle shell in his hand.

After holding the turtle shell tightly, Xiao Ling threw a few lower grade spirit stones into a heavy cutter beside him, and then turned on the switch. The shell is placed on top of the cutter incision.

The light and shadow flashed, the cutter pressed down, the gravity pressed on the turtle shell, not even a spark flashed, the cutter was fixed on the turtle shell, making a buzzing sound, but it did not move.

Seeing this, Xiao Ling carried the turtle shell to another laser cutting machine. The devastating energy light cut down, and the turtle's shell remained unchanged.

Xiao Ling changed the medicine to corrode and differentiate, and all kinds of extremely corrosive solutions were sprinkled on the turtle shell, but even the lines on it did not change.

Xiao Ling tried the cutting methods in the material purification room but did not disassemble and differentiate the turtle shell, and when it was time to get out of class, he had no choice but to put the turtle shell into the storage bracelet.

At night, sit quietly in the cave. These days, since Gao Fatzi concentrated on learning the course content, the night activities of the four members of the 145 cave room have also become a lot more monotonous. No more drinking and eating from the sea. They were busy studying and cultivating.

Xiao Ling also liked such a quiet life, and as soon as he sat down in the cave, he took out the 10,000-year-old turtle shell from the storage bracelet. His hands caressed the turtle shell for a long time, and his divine sense swept back and forth on it, but he still couldn't see the internal structure of the turtle shell.

After seeing nothing for a long time, Xiao Ling immediately injected the gray true yuan into his finger and darkened it on the turtle shell. The gray true element instantly blends into it. Xiao Ling was overjoyed in his heart, increased the output of the true element, and shot a gray attention from his fingers and injected it into the turtle shell.

After a large amount of gray true elements entered the turtle shell, a layer of clearly visible light slowly appeared, getting brighter and brighter.
