Ye Xing's divine sense condensed into a line, but he didn't dare to poke out, so he could only stick under the stone slab and listen to the vibrations from the stone slab, so as to know the conversation of those people.

Fortunately, the skill of obtaining information through vibration has been trained for a long time, and he has become extremely proficient, and to be honest, it is not that the other party's cultivation is too high, and he can directly attach his divine sense to the door of the secret room, and he can also hear it.

It's just a master, who usually scans the entire secret room, but generally doesn't pay attention to the solid underground, and fortunately, Ye Xing also heard a lot of details.

What is certain is that the internal and external hostile forces of the Celestial Star Kingdom have joined forces and are ready to massively kill and injure the monks of the Celestial Star Kingdom in the name of challenge, and it is very likely that the Yuanying Monks will be sent to contain the top personnel of the Celestial Star Kingdom, so as to achieve their goal of disrupting the Celestial Star Kingdom.

In addition to the fact that their conspiracy is not easy to handle, their conspiracy is also extremely large, and it is very likely that it is to snatch the latest technology of the Heavenly Star Kingdom, or this is the fundamental purpose.

Ye Xing's divine sense had been listening under the stone slab, but there was no more useful information coming from there, more about the value of the items that those masters were talking about, discussing some cultivation experiences.

Originally, this was an excellent learning opportunity, but his mind was suppressed by what was about to come, and he hurriedly withdrew his divine consciousness from the underground.

Ye Xing slowly withdrew his divine sense from under his feet, and immediately deposited it in the space ring, maintaining his cultivation that was not too high, then stood up, left the grass, and returned to the inn where he lived.

After setting up the isolation array at the inn, Ye Xing took out the long-wave radio station and passed the news that the three major sects of the Tang Dynasty would send masters to challenge the sects of the Heavenly Star Kingdom next month to the eyeliner of the "Nighthawk" in Shanglin City.

Not surprisingly, a day later, this news was sent to Li Yishan's hands, and the news pointed directly to the internal response of the enemy in the eight major sects of the Heavenly Star Kingdom, and it should be handled carefully.

Li Yishan and the staff of the Tianxing Army both received the news from Ye Xing on the same night, and held a meeting overnight to discuss countermeasures.

At the headquarters of the Tianxing Army, the generals did not have much contact with the eight major sects, nor did they understand their attitudes, but they still listened to Ye Xing's analysis and knew that in addition to winning the hearts of the people, the Tianxing Army was secretly maintained by the Xiuzhen boss of the original Song Kingdom, and explicitly ordered the eight major sects to return to the sect and not participate in secular disputes, and the Song family was also unwilling to give up secular power.

It's just that this is not easy to do, the Tianxing Kingdom has only been established for ten years, and the core task now is to develop and enhance the national strength, not to start a war with the old empires, let alone to settle old accounts with the traditional forces in the country.

How to deal with the thorny problems they are facing now is really a test for all the members of the General Staff, who used to have Ye Xing to provide advice, but now it is up to them to find solutions on their own.

The youngest member of the staff department, who was also recommended by Ye Xing, put forward a brand new idea, that is, to conduct a first-hand public opinion war, and also to force the eight major sects in the country to compete with foreign enemies, in essence, it is not a bad thing for the Tianxing Army.

Li Yishan and other high-level leaders quickly figured out how to contact the monks behind the eight major sects, it didn't matter at all now that they thought about it, and finally decided to announce it directly to the whole country, so that the forces of the sect would fight with each other, and the Tianxing Army would secretly help.

Early the next morning, a message was published on the front page of the nationwide "Tianxing Daily", saying that the masters of the Tang Empire and the Great Yuan Empire were coming to challenge the masters of the sect of the Tianxing Kingdom, and it was a life-and-death challenge.

As soon as the news was announced, all the people in the Celestial Star Kingdom were in an uproar, it turned out that the two empires were unwilling to accept a big defeat on the battlefield and wanted to find a place in other aspects.

Only then did the ordinary people of the Heavenly Star Kingdom know that in addition to martial artists, there are also monks in the country, and of course, their understanding is also the meaning of martial arts masters.

The Heavenly Star Army's move is still very practical and vicious, and now that it is announced, the sect that wants to be the internal response also has to participate in this challenge, and it has to go all out, because the other party is fighting to the death, and will never release water easily, and in front of everyone, it will not release water, and it will not be fake.

Now this challenge is all about the sect, it seems that it has nothing to do with the Tianxing Army, of course, it has to do with the face of the Tianxing Kingdom, so the sect does not dare not do its best, and the big guys behind it also have to put pressure on the sects, and they must go all out.

Ye Xing left Shanglin City, and after staying away, he quickly returned to the Xuanyue Sect in the secret place of the prairie.

Under Ye Xing's full strength, he also used a balloon, and it only took fifteen days to return to Xuanyue Sect, and he and Qi Ming directly took 30 of the most elite disciples to Songcheng with him.

After a brief conversation with Liang Zhihong, Ye Xing went to the factory in the belly of the mountain where the aircraft was produced and began to modify the aircraft and guns according to his latest design plan.

Qi Ming led the teenagers to train with the elite of the Heavenly Star Army.

These disciples have been training for many years, although they are young, their skills are not shallow, but their combat literacy and intolerance are still far from being compared to the elite of the Heavenly Star Army, and communication is the best eye-opening.

What Ye Xing wants to transform is the muffler of the gun, the structure of the bullet, add the formation, use a very small piece of spirit crystal to make the magic circle run, and the bullet is also directly filled with spirit stones, and the poison configured by Ye Xing is also added inside.

The formation is coupled with the newly formulated high-energy explosives, which makes the bullets fired faster, and uses the principle of the teleportation array to preprocess the trajectory of the trajectory, so that the sound almost disappears.

After the spirit bullet hit the target, the high-grade spirit stone would explode instantly, turning into a self-explosion of the most lethal spiritual power true qi for the cultivator, which could not be suppressed at all.

The cost is much higher, and each bullet has to use a small piece of high-grade spirit stone, and the barrel plus the carving formation, which can be said to be sky-high.

Fifteen days later, after transformation, there was no change in appearance, but the range was longer, and the special guns for sniping monks without sound were produced, Ye Xing himself tested three shots, and sure enough, hundreds of zhang away, there was no sound at all, with the latest design of infrared telescopes, the monk could be sniped hundreds of zhang away.

Ye Xing worked hard for another ten days, transforming dozens of guns, plus hundreds of spirit stone bullets, according to different attributes, spirit stone bullets also have five colors.

Ye Xing called Qi Ming, handed him the new gun, and after telling him how to use it, let him train a few potential disciples to become snipers, and at the same time, the top snipers of the Heavenly Star Army will also be equipped with more than a dozen such guns to protect the safety of the high-level in Song City.

Ye Xing continued to devote himself to the transformation of the aircraft.

The first thing to do is to change the design of several details of the engine structure and control mechanism, which do not need to be demonstrated and experimented, just use it directly, although the details have to be improved, but that is a matter of the future.

Sure enough, the high-tech design of the previous life was extremely powerful, and according to the environmental conditions here, it could be used with a little fine-tuning, and the performance of the aircraft was greatly improved.

The principle of bullet silencing is now also used in helicopters, that is, the formation is used to isolate the sound, and of course, there are some design details that can also eliminate noise.

What Ye Xing had to do was to design a protective formation driven by spirit stone automatically, wrapping the quadcopter so that the noise of the plane was not too loud to be transmitted.

In just ten days, the newly modified aircraft carried out a test flight, and Ye Xing personally piloted the plane for its first flight.

The results of the test flight were very good, only a few details were improved, so that the quadcopter took off and at the same time activated the protective array, so that the sound was transmitted very little, and then rose to a very high level, unable to see, so that it was completely silent, completely hidden.

Under Ye Xing's divine sense, everything in Song City was well understood, but the people in the city didn't know that Ye Xing was observing them in the sky.

Ye Xing once again modified the formation, he could map the adjacent sky on the magic circle, this was a hidden formation, and sure enough, when he went up to the sky again, Qi Ming did not find the plane in the sky with a telescope.

After Ye Xing came down, he modified the formation again, which could block the divine sense, that is, the monk's divine consciousness could not completely scan the plane, of course, the high-level monks ignored such a formation.

Based on the principle of the stealth plane in his previous life, Ye Xing scanned the divine consciousness to make the formation have the effect of displacing the divine consciousness, so as to achieve the effect of the invisibility of the divine consciousness.

It took Ye Xing twenty days, and the transformation of the aircraft was basically tested day and night, the principle was known, but the details had to be adjusted constantly.

Then Ye Xing personally led the team, allowing Qi Ming and 30 disciples to experience on the ground and in the air, and put forward various problems that existed, and each modification may only be a little bit of improvement, only twenty days, and thousands of corrections have been made before and after.

The two weapon technology plans formulated by Ye Xing have become high-tech spiritual weapons.
