The Tianyuan sword qi stimulated by the thunder attribute, only Lei Zi can use it in the entire Tianyuan Sword Sect. This sword qi was really unique, and after the Eagle King was hit, he immediately paralyzed his whole body and planted down. At the same time as the sword qi pierced it, the thunderbolt had already numbed its body, and there was no chance to escape and dodge at all.

Lei Zi unhurriedly made a move, and saw that one by one the Eagle King was stabbed down. After the attack of the Iron-winged Eagle and the demon beasts passed, there was a blank period. There is neither the impact of demon beasts, nor the demon cultivators to harass.

"Let's get all out and rest!"

Seeing that the Great Elder was still hesitating, the Four Elders came down directly to let the disciples reorganize and rest. Take advantage of the fact that there are no demon beasts to come, so that everyone can recover quickly. Then he hurried into the sect, as if he had something urgent to deal with.

"I need to make a trip. ”

"It's too dangerous, and if you get stuck in the middle of the road, you'll be in trouble. ”

"There's still a lack of this thing, and we need to get a batch of it. ”

"Let Lao Wang find it for you, the market is under martial law, and you can't get in. ”

The two people in the secret room were arguing fiercely, it was Yuan Tian who was talking to the four elders about going out to procure. It's certain that materials are needed to make armor, and the other parts are okay, but the spirit stone card slot is not easy to get. Yuan Tian didn't know how it worked, so he couldn't make it himself. You need to go to Tianyuan Market to find Shidong, even if you can't learn to make spirit stone card slots, at least you can buy a batch of finished products and come back.

In addition, in terms of the performance transformation of the chain crossbow, Yuan Tian also has some ideas. The chain crossbow is very useful, but it doesn't seem to be so effective when dealing with the demons. And in terms of penetration, there is also room for improvement.

The fourth elder Zhong Kui resolutely disagreed with Yuan Tian to go out of the mountain protection array at this time, although it was said that there were no demon beasts attacking outside for the time being, but no one could say when he would come back. If Yuan Tian went to Tianyuan Market alone, it would be troublesome if he fell into the encirclement of demon beasts halfway. As for the materials that Yuan Tian wants, he can find them from the sect's warehouse. It's an extraordinary time, and I'm sure even the head will agree to this request.

Although the Tian Yuan Sword Sect does not open a store, there are a lot of things in the warehouse. As long as the few members of the Council of Elders are all unified, most of the things can be used by Yuan Tian. Under the vigorous efforts of the four elders to stop him, Yuan Tian had no choice but to go out first. Wait for the four elders to discuss with the other elders, and if they can, they will send the king's steward to fetch it.

Yuan Tian made a list of the items needed and handed it to the four elders, and then began to make something. In this way, basically no one in the Cultivation Realm looked at it, because this was a technique from the Otherworldly Realm. This is a machine that can be used to process parts, and it is much faster to use this machine to process parts than to carve them one by one with a knife. Moreover, the size of the parts processed by this machine is exactly the same, and there will be no errors.

The machine manufactured by Yuantian is just a simple parts processing machine. Things like pulleys, triggers, quick reloading slots, etc., are all done on different machines. Time is tight now, and there is no time to build a comprehensive processing machine. For example, the machine for processing the trigger is actually a concave mold made by engraving and polishing. You only need to melt the dark iron into molten iron at a high temperature, then pour it into a concave mold, and then perform ice attribute exercises to cool it down quickly, and the trigger will be quickly produced.

The pulley is also produced in the same way, but the structure is slightly more complex than the trigger. The more complicated thing is the manufacture of the crossbow body, as it requires some dimensional precision. The machine itself should have the function of calipers, and there are several sizes that need to be adjusted in the process of processing. Once all the dimensions are set, you can start machining quickly.

Because of this kind of chain crossbow of the Tian Yuan Sword Sect, it is different from the ordinary crossbow in the outside world. So many accessories can't be bought directly, but fortunately, Yuantian is quite proficient in physics and mathematics, which is not difficult for him. Now the problem of literature and art is to see if the four elders can get the spirit stone card slot. As for the conveying trough of the spirit stone, Yuan Tian had already figured it out. As long as it is a material that can be transported smoothly by spiritual power, you can make it in large quantities if you set the size yourself.

The four elders went to discuss matters with the other elders, and Yuan Tian had already made the molds and processing machines he needed in the secret room. This time, he didn't hide it, he just put it there when it was ready, and waited for the four elders to negotiate it, and Steward Wang could find what he needed from the warehouse.

There are still a lot of things like Xuantian in the storage ring of Yuantian. Simply set up the mold for casting the trigger first, and use the fire attribute exercise to turn the dark iron into molten iron and pour it in. It is a simple mold with exactly 100 grooves of the same size and shape. After the molten iron was all poured full, Yuan Tian used the cold attribute of Tian Yuan's sword qi to cool down the mold.

The molten iron poured into the mold is quickly solidified after quenching. After returning to normal temperature, Gentian poured them all out.

"Whoa......

A bunch of blackiron triggers were poured on the clean table, and the silver glitter was quite good-looking. The original black color of the rough stone has been treated with high temperature and quenching to turn into its current silver glitter.

"Boy!"

Steward Wang came in happily, and was even happier to see Yuan Tian lying on the table with a large number of triggers. Looking at his expression, he knew that he must have got what he wanted.

"Here we go!"

Seeing that the king was happy, Yuan Tian also had a good temperament. The mouth was talking, and the hand really didn't stop, and some dark iron water was melted and poured into the mold.

"Here, you have everything you want, but the spirit stone card slot is a little less. ”

Speaking of which, Steward Wang was still a little embarrassed, he originally thought that he had gotten a lot of these. But seeing the speed at which Yuantian made parts, he realized that the little material he got might not be enough. Especially the spirit stone card slot, I only got more than a hundred.

"Whoa......

After quenching, and then a little warmer with slow fire, another hundred triggers were machined. Yuan Tian turned the Qiankun bag handed over by Steward Wang, and took out the spring steel inside. This is the material used to process the crossbow body, and it is the most consumed one.

It is also melted at high temperatures and then poured into a mold. There is currently only one mold for this complexity, so only one crossbow can be machined at a time. The crossbow body is poured as a whole, and there is no need to spend any more time fusing some places into everything. After the quenching treatment, Yuan Tian did not pour it out directly. Because the structure of the crossbow body was more complicated and could not be poured out directly like a trigger, he broke it in a few places with his hands, and then took out the crossbow body. After taking it out, don't forget to measure the size parameters everywhere. found that there was no problem, and took out a spirit stone card slot and installed it.
