Yin Nian bent down and picked up the knife, and it was cold in his hand.

As for the grooves on the handle, they are actually used for inlay formations.

This is the part that every bone tool must be made of.

"It's a strange weapon." When the old man saw the knife, his eyes lit up.

Although he didn't know how effective it was, judging from his decades of experience in refining, there was definitely something special about this knife.

"Let's try it first!" Yin Nian casually turned the bone knife around his fingertips twice, and then threw it violently towards the pile of materials not far away.

Just listen to the soft sound of "Zheng".

The bone knife actually cut directly through several pieces of hard metal and ore, and finally nailed it firmly to the ground.

The old man didn't expect Yin Nian to make a move.

I wanted to remind her to go to the test room, but when he saw the power of the bone knife, he was completely speechless.

"How is this possible......" The old man's eyes widened in disbelief.

You must know that the knife refined by Yin Nian did not use any other materials except for the eight kinds of beast bones.

Except for those potions.

But even so, it shouldn't be so powerful!

It directly penetrates through so many high-hardness materials, and also penetrates the ground by seven or eight centimeters.

This is a star tower.

The building materials used, that are all of the same class.

Roughly speaking, the power of this knife is comparable to that of a D-class alloy weapon.

That's not the point.

The point is, why is the weapon made of beast bones so sharp?

Isn't this thing supposed to be brittle?

"Teacher, did you see that I passed the test?" Yin Nian looked at the old man and said.

"Tell me first, what ancient book does this refining method come from?" The old man asked expectantly.

"Just a tattered book I bought on the street, I don't know where I lost it after reading it." Yin Nian said casually.

"You kid, how can you just throw books around!" The old man's face was full of hatred that iron could not be made of steel, "Okay, even if you pass this test, but you have to keep this bone knife." ”

"But this is the ...... I refined," Yin Nian was a little reluctant.

She was now short of a weapon that would be easy to use in her daily life.

A long knife made of Yin Soul Iron, although it is infinitely powerful.

But after all, the material is special, so if you take it out and use it like this, you have to be targeted every minute.

So it wasn't a last resort, she didn't want to use that weapon.

"I still provided you with the materials you used!" The old man glanced at Yin Nian angrily, "It's a big deal, I'll let you use the materials and instruments here to refine another handful, and then you can just keep a handful for me." ”

"Okay." Yin Nian nodded.

……

In the end, Yin Nian used the materials on the scene to refine another long sword for the old man.

It's just that she didn't reserve a place for the inscription formation on it.

This technique is inconvenient to expose.

It can't be seen for the time being.

However, after the old man got the long sword, he was very satisfied.

He thought the groove was for ornamentation.

At his age, he wasn't interested in all the bells and whistles, so this long sword was obviously more suitable for his aesthetics.

"I've already entered the information of your student card into the system, and you can just bring the card to class when the time comes." The old man had been holding the long sword in his hand, and he was reluctant to put it down even when he was operating on the computer.

"Then thank you, teacher." Yin Nian said politely.

"There's nothing to do, you can go." The old man waved his hand at Yin Nian, he had to study what was going on with this weapon.

If you can master this new technology, it will definitely be an achievement no less than that of alloy weapons.

……

Yin Nian returned to the dormitory.

As a result, when I opened the door, I found that there was someone in the living room.

Those were two girls in their twenties.

They were holding the tablet, and they were excitedly discussing something.

Hearing the movement, they looked up in the direction of the door.

"Hey, why haven't I seen you before, you're new here?" Luo Meishi asked curiously.

"Meishi, this person seems to be in Yinnian!!" Yang Qinghuan suddenly grabbed Luo Meishi's arm beside him and said with excitement on his face.

"Damn, it seems to be true!" Luo Meishi also reacted, she quickly stood up, trotted to Yin Nian, kept looking up and down, and then asked tentatively, "Are you Yin Nian?" ”

"How do you know?" Yin Nian was originally surprised by the reaction of these two girls, looking at them, it seemed that they knew themselves, but they didn't seem to know themselves, and they were very excited to see themselves.

Could it be that the geniuses of the Hidden Dragon Academy have such special brain circuits?

"We were still watching your "Non-Evil" just now, but I didn't expect you to be our roommate, this world is too small!" Yang Qinghuan also put down the tablet and ran over.

"Yes, yes, yes!" Luo Meishi nodded, "We like this drama very much, I thought you were in Lanxing, but I didn't expect us to be a school!" ”

"You also chase the drama over there?" Yin Nian was a little surprised.

"Of course, the TV series here in the Xingyang Realm are more inclined to fight and kill, explore and hunt for treasures, if you want to see sweet love, it is better to shoot it on the side of Blue Star." Luo Meishi said with her face in her hands.

"Makes sense, too." Yin Nian nodded.

"Yin Nian, I remember that you are not a student of Imperial Capital University? Why did you come to Qianlong Academy? Yang Qinghuan asked gossipingly.

"I transferred to another school halfway through." Yin Nian said.

"That's it!" Yang Qinghuan paused, and then smiled: "By the way, our dormitory is full of first-year students, in addition to the three students from the Department of Medicine, there are two from the Department of Biochemistry." ”

"Qinghuan and I are both from the medical department." Rome added on the side.

"Well, I'm also from the medical department." Yin Nian replied lightly.

"Haha, I found that Yin Nian is really the same as what was uploaded on the Internet, there are not many cruel words, but the real person looks much more beautiful than on TV." Yang Qinghuan chuckled.

"Well, I don't talk too much." Yin Nian did not deny it.

"You're so interesting." Luo Meishi also has a good impression of Yin Nian.

It's one thing to chase stars online.

But as a student of Qianlong Academy, they all have their own arrogance.

I don't feel like I'm a fan, so I'm inferior or something.

However, their first impression of Yin Nian was indeed good.

Although it doesn't look easy to approach, he speaks with a polite attitude and is humble.

It's easy to get a good impression of people.

"Yang Qinghuan, Luo Meishi, you two are chasing stars and chasing your head, what kind of good thing can this kind of person in the entertainment industry be, you really treat people as idols?"

At this moment, a girl in cool clothes walked down from the second floor.

She glanced at Yin Nian lightly, her face full of disdain.
