In this entire spiritual treasure house, there are no more things that can be directly used by the three of them now.

But when it comes to meteorites and mineral crystals of astonishing value, there are indeed a lot.

Either choose the rarest and most valuable of them, even if you can't use them, you may be able to exchange them for suitable things after you go out, just like Xiao Suxin exchanged Huang Yadan for the sponsorship of Nantian Courtyard.

Either choose to practice in the future, which should be of great use.

"What Qi Zhuji's family should have is money, and even if it is the most valuable thing for exchange, it is unknown whether it can be exchanged for what he needs, and if he takes something that will be useful in the future. ”

Lin Yi weighed it again and again, and finally took a psychic stone.

This divine stone is also a unique meteorite, which is used in the world of cultivators to be inlaid on flying swords.

This spar, like many special essences used to refine the Flying Sword Fetus, is more likely to be perceived by cultivators and more easily accepted by cultivators.

The reason why the Tongshen Stone cannot be used directly to refine the sword tire is that it is too hard to cut at all, nor can it be mixed with gold and iron to melt or forge.

The larger the channeling stone, the stronger the effect.

In a note that Lin Yi has read, it is recorded that the largest Tongshen stone found so far is the size of a baby's fist, but the rest are normal only the size of rice grains and soybeans, and now this Tongshen stone in Nantianyuan is the size of a broad bean, which is also amazing.

If such a divine stone was embedded in a flying sword like the Tongtian Sword in Xiao Suxin's hand, it would instantly multiply the power of this flying sword.

If the flying sword controlled by a cultivator was originally at a limit distance of 100 steps, with a spiritual stone inlay of this size, I am afraid it would be able to kill at least 200 steps.

"Seniors. ”

Lin Yi selected these three things, grabbed them in his hands, and when he arrived outside the warehouse, the old man half-squinted his eyes, looking like he was about to wake up.

Lin Yi spread out these three things in front of the old man, and before he could say more, the old man was already unwilling to say more, waved his hand, and let Lin Yi leave.

"This...?"

Lin Yi was suddenly a little stunned.

He held his hands up, and the pile of crumbs on his wrists wanted to say something about himself, but the old man didn't seem to care.

But he is not a pedantic person, he doesn't say any nonsense at the moment, turns around and leaves.

What he didn't know was that when his figure disappeared in front of the Spirit Treasure House, Guan Lianhuang's figure appeared in front of the Spirit Treasure House.

Guan Lian Huang arrived in front of the old man, bowed his head, then turned to look in the direction Lin Yi left, smiled faintly, and said, "Not bad?"

The old man opened his eyes slightly and said, "Very good." ”

"Very good?" Guan Lianhuang was also a little surprised, he didn't expect Lin Yi to get such an evaluation.

"What could be more temperamental than entering the treasure house?" the old man said with some ambiguity: "What's more, it's naturally very good to have such strength when you first enter the Yellow Bud." ”

......

"What's so heavy?"

Lin Yi thought that since the library building could enter at any time, he was not in a hurry, so he went back to the Yellow Teng Jingshe directly, tied a thick cloth on the fingers of his left hand, and removed the crumbs on his right wrist one by one.

When he found that the debris he had removed was not heavy, he let go, and the crumbs naturally attached to his left bracelet.

Just after taking more than ten crumbs in a row, his entire left arm was already extremely sore, especially the five fingers of his left hand were even more swollen and painful, and he was constantly shaking.

After resting for a while, Lin Yi took it again when the soreness disappeared.

This time he only took the third one, and his entire left hand suddenly sank, and the fingers of his left hand couldn't hold it directly, and this time he saw it clearly, it was a pale cyan chip like the tip of a sword that was only the size of a fingernail.

"This is a meteorite?"

Lin Yi's eyes widened in surprise.

The surface and fractures of this translucent wafer are very smooth, but they are not absolutely flat, and there are obvious traces of natural collision and friction, and even burning and melting.

This is definitely a unique meteorite, and the Northern Wei Dynasty is also called the Heavenly Law Crystal.

But in all the notes he had seen before, there was no record of this meteorite at all.

Lin Yi tried to use this meteorite to scratch the rocks on the ground.

Stone chips are flying, and this meteorite piercing ordinary mountain stone is like an iron tool piercing into a hard mud block, which is extremely easy, but the sharp end of the meteorite crystal is not damaged in the slightest.

"This ......"

For a while, he felt a little hot potato.

This kind of meteorite crystal is so heavy and extremely hard, if it is in the hands of the master of the Southern Heavenly Academy, it should be of great use, but for him, such a piece of it is known to be an extremely special thing, but he does not know how to use it.

In fact, to test the material properties of this meteorite, the craftsman should have many means, but he can only try it so simply.

"It's a good pair of bracelets, but sometimes it's going to be troublesome, so you have to prepare something to block the magnetic force. ”

Lin Yi recognized this meteorite, and at this time, he looked at the circle of debris on his wrists, but he was also helpless.

The magnetic force of this pair of bracelets is too powerful, and if you go to the battlefield, I am afraid that it will be inconvenient, not to mention that sometimes you can not hide this pair of bracelets with you, and you may not be able to hide your hidden figure, and if an enemy approaches, the things on the other party's body may be sucked over.

"When the time comes, ask Wu Jiaoxi if there is a solution. The meteorite also gave her a chance to see what it could be used for. ”

Lin Yi really had no choice, so he reluctantly removed the bracelet on his right wrist and put it in the house, and then it was like a finger practice, and it took a long time to take a stick of incense before he took off all the crumbs absorbed by the two bracelets and put them in a clay pot.

The most unique meteorite was wrapped by him alone.

"Lin Yi!"

After he finished all this, he had just rested for a while, and he hadn't decided whether to simply practice for a while, or then go directly to the library of Nantian Courtyard, but the shouts of Qi Zhuji and Xiao Suxin had already sounded outside the bamboo forest.

"What's the matter?"

Lin Yi was stunned when he saw Qi Zhuji and Xiao Suxin coming.

Mo said that the look on the faces of the two of them was that something big had happened, and just the two of them shouting outside the forest from a distance made him feel that something unusual had happened today.

"With the arrival of the oracle, we are about to set off. ”

"Wu Jiaoxi was originally in class, but someone from the Chinese military department came and brought a holy message, ordering us to leave the hospital immediately, the military has prepared horses, and we only have a cup of tea to prepare. ”

Qi Zhuji and Xiao Suxin said a word alone, their tone was eager, Lin Yi instantly understood, and was also taken aback, "What do you mean, Nantian Courtyard will move north immediately?

"All of them left the hospital, but they were led by different teachers. ”

Qi Zhuji's face was very ugly, "Even Wu Jiaoxi was surprised, it seems that according to the holy decree we received in the courtyard before, we will leave the hospital at least ten days later." ”

"Could it be that the situation on the front line is already tight?"

Lin Yi took a deep breath, his heart solemn.

"The change was too hasty, and I didn't have a warning in advance, so I'm afraid even my family didn't know what was going on. Qi Zhuji frowned deeply, and he didn't hide it, "Lin Yi, what did you get?"

"I went to Danfang and Lingbao Palace, but I haven't had time to go to the library yet. Lin Yi quickly said what he had gained, and he couldn't help frowning.

I have to leave the hospital immediately, not to mention that I don't have time to go to the library building, and I can't deal with this pair of bracelets.

"You've gotten so much?"

Qi Zhuji was relieved when she heard what Lin Yi said.

What he is most worried about now is that after leaving the hospital, they will be handed over to the military for distribution, but some of the military's transfers are secret military orders, and I am afraid that the communication with his family will be cut off.

"Now just let you come back and pack your clothes, then you won't even have time to choose ordinary blades?" Lin Yi frowned and then asked.

"It's said that it has its own rations along the way. Xiao Suxin said.

"This bijiao tendon will be brought to you first, in case we are scattered... When you have the opportunity to touch the bow and arrows, choose a bow and take more bows and arrows. Qi Zhuji, you have this refining stone with you, I don't have time to dispose of these medicines now, if I have the opportunity, I will divide it into three parts and tell you how to use it. After all, Lin Yi is a disciple of Jiangmen, although today's change is abrupt, but it is only a breath or two, and he will decide.

"Good!"

Qi Zhuji and Xiao Suxin didn't waste any time, and the three of them went back to the house to pack their clothes.

It felt like it had only been a moment, and the drums were already beating in the entire Nantian Courtyard.

Originally, it was a twilight drum.

But now the drums are urging all the students to start rally.
