Listening to Xu Tian talk about the festival with the city lord, Custer laughed so much that tears flowed out: "Okay, okay, don't be like her, she is just a little girl after all, although she is also very good among the city lords of the past dynasties, but after all, she is still young, I will help you find it tomorrow."

When you go to Bol them, you better play the mission first, although I have been researching for a long time, but my ability is not as good as Melissa's, and I can't do anything about her missiles, this time I can only rely on you. ”

The two of them said, and they had arrived at Custer's residence: "You will stay at my house tonight, I am very spacious here. ”

Xu Tian was not polite to him, and lived in it directly, the two of them chatted while having dinner, Xu Tian suddenly remembered one thing, the last time he solved the incident of the flame rat, he got a stone from the village chief, and Xu Tian could feel that it contained a powerful thunder attribute, only

I don't know how to use this thing, but today I just asked the doctor, he is very knowledgeable, maybe he will know.

Taking out the stone, Custer's face changed slightly, and Xu Tian immediately knew that it seemed that he had asked the right person.

Taking the stone, the doctor looked at it carefully, and then said with some excitement: "This is a good thing, as far as I know, hundreds of lightning strikes on the same stone to make it produce thunder attributes, the probability of this situation is very low, hundreds of lightning strikes on the same stone."

This probability is almost impossible, and hundreds of lightning strikes, the stone is not damaged, which is impossible, but once the impossible becomes possible, this magical stone is produced. ”

"Then what's the use of it?" Xu Tian didn't care about what might be impossible, he only cared about whether this thing was useful or not.

"This stone can't be used directly, it can be used as a storage device for energy, and the thunder and lightning power inside can be released through some kind of tool, so you may not understand, so I'll just say it, for example, there is a knife, install this stone on that knife, you can let it

That knife turned into a divine weapon with thunder attributes. ”

"Damn, you're saying that you can use this stone to make an artifact, that's too good!" Xu Tianxi said.

"Don't be so happy, you must know that this is a thunder attribute stone, the knife is metal, and the metal is conductive, if you really use it, the enemy has no electricity, and you yourself have not been electrified. And the power emitted with this stone is too strong for the hardness of the metal to withstand at all, and so do you

It's hard to find something hard enough to make a weapon, that is, stone is a good thing, it's just that we don't have the conditions to use it. ”

"Hard things?" Xu Tian said, took out some things from the space capsule Li and put them on the table, the hard skulls of the spirit beasts obtained in the forest near the Garba Jiya Academy some time ago, the teeth of the gold-eating rats and the teeth of the dragon that were obtained in the Calfa Star before,

There is also a cosmic stone, these things are extremely hard, Xu Tian didn't know what these things were used for at that time, and he didn't know if these things could come in handy today.

Dr. Custer looked at each of these things, and the more he looked at them, the more shocked he became, they were all very hard things, even beyond the knowledge of this learned scientist.

"Doctor, are these things okay?" Xu Tian asked with some apprehension, if none of these things worked, then it was really hopeless.

"Yes, of course, if you make a knife out of these materials, and add this stone, you will definitely be able to create the most powerful weapon in the world. Dr. Custer was so excited that he was dancing a little bit.

Putting all these things away, the doctor waved his hand at Xu Tian and said, "You go and rest, give me a night's time, and I'll give you a divine blade tomorrow morning." Looks like it's been a sleepless night!" the doctor said as he stepped into his research

。

Xu Tian could only lie on the bed alone in a daze, since the Kunlun blade was also broken, he had not fought with a weapon for a long time, what he was best at was knife technique, there was no knife in his hand, his combat effectiveness was greatly reduced, and now he could finally get a knife, Xu Tian

How can you not be excited.

It's just that Xu Tian is also a little curious, since those materials are very hard, how can the doctor turn them into a knife, and it is only a night time.

It took Daddy ten years to build the Moon Slash, Mr. Mu Yi also took three years to build the Kunlun Blade, Yuan Liubo's magma sword also took three years, and the time to build the artifact was calculated in years, Xu Tian really couldn't figure out what kind of method Dr. Custer would use

law, can create an artifact in one night.

With apprehension, Xu Tian survived the night, and the next morning, he waited outside the door of the research room early, waiting for the doctor to come out with anticipation.

After waiting for two hours, the doctor finally opened the door, and Xu Tian immediately said, "Good morning, doctor, why did you come out so late?"

The doctor rolled his eyes, "It's so late, it's only four o'clock in the morning, okay?" ”

Xu Tian smiled awkwardly, and then he realized that it was not that the doctor came out too late, but that he got up too early.

"That, what's wrong with the knife?" Xu Tian scratched his head and asked, this was the question he was most concerned about.

Dr. Custer saw that Xu Tian couldn't wait, and also smiled, he asked Xu Tian to go in and take a look by himself, Xu Tian was not polite, and rushed into the research room in a flash, and saw the knife lying on the table at a glance.

The knife is one meter long, and it looks cold, just by looking at it, it can make people shudder, and when I touch it with my hand, I can't feel what kind of material it is, I can only feel the coldness of the bone.

On the body of the knife, an electric current travels upstream and downstream, and only a person with a thunder attribute like Xu Tian can touch it, and other people will be burned into charcoal by the current as long as they touch it, such a powerful spiritual power is breathtaking.

At the bottom of the hilt, the thunder attribute stone was inlaid on it, and a steady stream of energy was transported from the stone to the knife body, such a knife simply fascinated Xu Tian.

"Try its power. Custer said, leading Xu Tian into another room.

It was an empty hall with no windows, only the metal door that came in, and Custer said, "There is a special barrier here, you can try the power of that knife, don't worry, the facilities in the room will cancel out the energy, don't worry about destroying the house." ”

Xu Tian picked up the knife and swung it hard, the imaginary power of destroying the world did not appear, everything was so calm, Xu Tian waved it a few more times, and the room was still as calm as water, without any change.
