After thinking about it, Ye Xing finally decided that there was only one way, and that was to use scientific and technological means beyond this era to find a solution.

Ye Xing's head is very useful, when he enters the meditation, he has a specific goal, and he thinks desperately, and some of the knowledge of his previous life can be slowly searched out, but this process is a little slow, and it consumes extremely brain power, and he will soon be paralyzed.

Fortunately, the starlight qi in the sky always enters the brain when Ye Xing is about to hold on, and it is constantly replenished, so that the fatigue of the brain is relieved.

Now, Ye Xing can easily recall the general, theoretical knowledge, and can also make extremely long-term calculations and simulations based on it, but as long as it involves the design of advanced technology, it will be very laborious, and it will take a long, long time to extract from memory, and it is very exhausting.

Although Ye Xing actually has a vague impression of every high-tech in the previous life, once it comes to technical details and production details, there is no way to remember it at all.

There is also a good thing, that is, once the high-tech details in the memory are successfully read, then the reading again will be extremely fast, and the deduction based on this will also seem easy.

At dawn, Ye Xing innovatively deduced the design of the original quadcopter, the design of the stealth rotorcraft, which is a mini small aircraft that can only seat 5 people, plus the hidden array he designed, the isolation array, which can greatly reduce the noise, isolate the detection of divine consciousness, and fly higher and faster.

This is the first time that Ye Xing has combined the high-tech of his previous life with the knowledge of this world's cultivation formation, and re-optimized the plan in terms of appearance, rotor engine efficiency, material selection, and layout arrangement.

For Ye Xing, this is also groundbreaking thinking, no longer limited to the knowledge of the previous life, but combining the technology of the previous life with the current cultivation, and now I don't know what the consequences will be, but the stealth small aircraft plan is an attempt.

The next day, throughout the day, Ye Xing did not go to those small underground fairs again, and continued to stay in the room to retreat, in fact, he did not cultivate, but fell into meditation again, and tried his best to calculate the idea of using the formation to improve the gun.

Spiritual Qi Bomb, Spirit Weapon Musket is a very creative idea, after listening to the words of that Extreme Weapon Sect monk, Ye Xing felt at that time that maybe it was a weapon that could deal with a master of cultivation, and it had to be designed immediately.

After a day and a night of hard work in his brain, Ye Xing finally took out the design plan of the aura gun, because this is an extremely fine design, every detail, Ye Xing has gone through thousands of times of reasoning, and finally in the brain, tens of millions of times of simulation, before the final draft.

This is the first kind of spiritual weapon designed by Ye Xing, which is specially designed to snipe the spiritual qi gun used by the cultivators, with a physical spiritual energy bullet, which contains an extremely deadly spiritual poison for the monks, as well as a different kind of true qi, and what is required is a silent high-speed, unavoidable long-range combat spiritual weapon.

Ye Xing's design plan is to borrow the principle of the teleportation array, and he has now thoroughly understood all the details of the teleportation array, that is, to drive a vacuum channel at two coordinate points in the space, and form a conveying package with spiritual energy on the array disk, and this true qi package moves in the vacuum channel at an extremely high speed.

The teleportation array disk is very important, and it is also the key to the teleportation array, which is how to design a channel on the array disk to communicate with the target point, and then form an aura pack, and then shoot out the aura pack.

The array disk used on the aura gun should be extremely small, and the core is to set up a teleportation array disc on the barrel, change the style of the array disk, design it into a circle, wrap the aura bomb, and activate the loading explosives of the aura bomb with a buckle machine, and also stimulate the teleportation array.

The aura bomb is also loaded with high-energy explosives, and the firing pin used for firing is made of spirit crystal plus hard metal, which makes the explosives explode at the same time, and also stimulates the teleportation array, so the speed of the aura bullet is 20 times faster than the existing gun bullets, and no Jindan monk can avoid it, and theoretically the Yuan Infant Realm monk can't do it.

Ye Xing also designed a spirit measuring array with automatic aim, within 2000 zhang, as long as there is a significant aura on the opponent's body, the crosshair of the aura gun is naturally calibrated, aiming at the target's strong aura, theoretically the blind man can also kill the master of cultivation.

It was still just a design plan, but Ye Xing was sure that as long as it was tried and tested, it would definitely be able to be manufactured, and then as long as it was equipped with such a combat unit, even a large army of high-ranking monks could easily defeat it.

Looking at the two important design plans in his hand, Ye Xing also breathed a sigh of relief, the crisis must be solved by finding a way, not waiting for it to come! As long as a solution is found, the crisis is a turning point.

Whether it is feasible to turn the corner now is not yet confirmed, but I have no other immediate solution than the many technologies in my mind that are ahead of this era, and maybe this is the real means to turn things around.

As for the issue of nuclear weapons that Ye Xing had thought about, it was too serious, and it was too hurtful and violated, so let's not do it yet, we can only put it aside.

Ye Xing had seriously thought about this question, the terrible power of nuclear weapons was a means that could be used to destroy the enemy, and it was better not to use it unless it was absolutely necessary, but he thought that maybe he had to make it first before he could have the capital to consider whether to use it or not.

Ye Xing is a person with a strong sense of crisis, and he will always do everything possible to find a solution before the crisis comes, and make more preparations.

Ye Xing didn't go out at the inn for several days in a row, and he was also waiting for the trade fair held by the Great Yuan Imperial Family in Shanglin City, this kind of government-run trade fair is only once every five years, and it is an item trade fair specifically for senior monks.

Shanglin City, the government-run trade fair, is only held once in five years, the items are relatively large, but also expensive, most of them are precious and strange items plundered by Dayuan from the conquered land, people from more than a dozen neighboring countries will come, there are a lot of people to the meeting, and the meeting lasts for nine days.

The government-run goods fair is controlled by the Dayuan royal family, and the Dayuan Empire is the most extensive country in the world, and it is also the source of many key resources.

The Great Yuan Empire is indeed a relatively special country, the entire Great Yuan tribe is mainly cultivated, and the other tribes can generally only practice martial arts, although there are also a large number of loose cultivation, but at most they can only be enthusiasts, but they do not have too high status.

In order to control the countless other tribes in the country, the Dayuan clan generally tries their best to weaken these tribes, and every foreign war will have a plan to make them cannon fodder.

Such a policy, in the final analysis, is that although the population of the Great Yuan Clan is the largest, for the vast territory of the Great Yuan Empire, the population is still too small and too small, and a single Great Yuan tribe is not enough to control such a vast area, but it is also necessary to guard against the resistance of other tribes inside.

It is said that every time there is a trade fair, the sect forces of various countries will send people to come, and the sects of the Heavenly Star Kingdom will also have people, and the sect monks who come are often some masters who are not born and are not famous, as for who comes, it is unknown.

The sect of the Heavenly Star Kingdom must have also sent masters to purchase materials for cultivation, Ye Xing didn't even inquire about any of them, according to the last information he knew, he probably also knew that only masters above the Jindan Realm could participate in the highest-level item fair held by this Great Yuan Clan.

There is no high cultivation, in fact, when you come here, you may not be able to leave the Great Yuan Empire, and if you leave Shanglin City, the Great Yuan Empire will absolutely ignore your safety.

These Jindan monks, in fact, will not reveal their true identities, they all restrain their breath, and also change their appearance, and then when bidding for items, they will not make people worry.

In the ten days of Shanglin City, Ye Xing didn't even see any Jindan monks, it was definitely not nothing, but it was very likely that they were all astringent, as for their appearance, they didn't know anyone in the first place, so they didn't care.

Ye Xing actually didn't have any exchange items in his hands, the spirit stone was originally what he needed, and the elixir and elixir couldn't be too revealed, he actually had only one purpose.

It is to inquire about the detailed plan of the enemies against the Heavenly Star Country, and it is best to find out the forces of the Heavenly Star Country, colluding with the hostile forces, this is the only thought of Ye Xing at present.

Only by detecting relevant information can we make targeted countermeasures.
