The sect master was in an extremely comfortable mood at the moment, this battle was successful, and that Yuan Shi vein was enough to support the future development of the Xuanyuan Heavenly Sect, and the great unification that the sect masters of the past dynasties dreamed of would be realized in their own hands.

Of course, all of this is due to Xianning's research on the relics of the Great Shang Kingdom in recent years, which has made the strength of Xuanyuan Heavenly Sect skyrocket.

"Ha Lu Ha ......" The sect master couldn't help but laugh loudly: "The Qiankun Empire thought that we were going to make a detour, and I definitely didn't think that our purpose was to wait for these two trebuchets...... It would be even better if they divided their forces, and it would be much easier to capture the Sixth Legion garrison!"

Xian Ning's face brought out an unhealthy paleness, and he smiled at the corner of his mouth, and said, "Sect Master, the other party's kind of flying light, I have also studied it!"

"Oh?" the sect master's eyes lit up, and he couldn't wait to ask, "Really?"

"It's actually very simple, just put a cover on the light and you can fly...... I also found it by accident, but the principle is not clear!In addition, it is not good to use oil lamps directly, it is better to use candles sold by the world's trading houses!"

The sect master nodded: "It's good to study it, the candle must have been made by Jiang Xingchen, let's go back and study it, you don't have to worry, you must protect your body!"

Xian Ning didn't follow the sect master's words, but continued: "This flying light seems simple, but it is difficult to use in practice, and the grasp of weight, wind speed, and time must be extremely accurate...... Jiang Xingchen can use it to burn gold and build a city, this kind of calculation can make it really amazing!"

Xian Ning said. There was a hint of admiration and admiration in his eyes.

"Jiang Xingchen is indeed a genius, but Xian Ning is not bad at you, only chariots, crossbows and trebuchets. These two things are enough to set the general trend!" the sect master comforted softly.

Xian Ning smiled and muttered, "I'm just wondering, how could Jiang Xingchen have so many wonderful ideas, the methods he used were definitely not what could be obtained by studying the relics......"

"Xian Ning, don't think about it so much, you're tired all day long. I'll get you some tonic medicine again, and let Doctor Chen Xun recuperate for you in a while!"

"Sect Master, the agarwood I gave last time hasn't been used up yet......"

Xian Ning wanted to shirk it. But the sect master interrupted it with a wave of his hand and directly ordered him to go back. Then he commanded loudly: "Come on, quickly transport these two trebuchets to the front line of the Tongyu Kingdom, and be sure to arrive within twenty days." Make no mistake!"

After instructing the trebuchet to be carried away. The sect master looked into the distance with his hands behind his back, and muttered in his mouth: "Jiang Xingchen...... In the future, it will be used by my Xuanyuan Heavenly Sect, and only here can you play a greater role and embody more value......"

Far away in the Xingchen Collar, Jiang Xingchen, who was meditating, suddenly sneezed, his divergent eyes began to condense, and then scolded: "Paralyzed." Who is scolding the old paper behind his back, if I know. I have to give you a dragon, it must be an old man...... Hmmm!"

Suddenly, Jiang Xingchen's words came suddenly, and a lightning bolt flashed in his head: "Take the dragon, the bicycle, the torque...... That's right, the torsion spring, which uses torque to accumulate force, converts mechanical energy into torque, and then releases it, so that a ballista can be operated by three people, two people control, and one person is responsible for firing!"

With this idea, Jiang Xingchen immediately began to study the structure, writing and drawing on the white silk......

When the craftsmen saw that Jiang Xingchen had thought of a way, they all gathered around and stared at the white silk. Soon after, all of them let out a cry of amazement: "What a clever way to charge power, and actually drive the crossbow arm like this......"

At this time, Han Xiaowu came running from a distance and delivered a letter from the marshal.

Jiang Xingchen took a look and immediately asked the craftsmen: "Now that the launcher is basically solved, let's run at full capacity, how many ballistas can be made in half a month?"

Everyone thought about it, and one of the craftsmen said: "If the materials are sufficient, we should be able to make more than forty units in half a month!"

Jiang Xingchen shook his head when he heard this, and said, "This amount is far from enough!"

"Sir, our manpower, we have made forty units in half a month, and we are already doing our best!" said the craftsman.

Jiang Xingchen thought for a while and said, "Let's split the ballista first, plan the specifications of various parts, and then each person is responsible for the production of one part, and then assemble it after the last!"

This kind of assembly line method can greatly improve work efficiency. At the beginning, he used it in the sheep intestine workshop of Zhaojia Pharmaceutical, and the effect was extremely significant. Now as soon as he said that the yield was not enough, he immediately remembered this method.

The craftsmen's eyes lit up when they heard it, and they knew that this method was feasible as soon as they heard it, and they couldn't help but sigh secretly: "Such a simple and feasible method, why didn't we think of it......"

After deciding on the production method, Jiang Xingchen said to Han Xiaowu: "Reply to the marshal, after half a month, I will personally go to the Sixth Army garrison!"

"Okay, I'll go!" Han Xiaowu agreed, turned around and trotted to send the letter.

At this time, in the Imperial Capital Noble Management Center, the father and son of the Yuan family and a handsome young man were laughing and talking.

"I really can't imagine that the peak will turn around, what if Wei Ning recovers from his injury, the position of the commander of the Eighth Army will fall to you Fang Wuwu at the end!" Yuan Hao said with a smile.

"The Tongyu Kingdom is roundabout, and the Sixth Legion is forced by the opponent's chariot machine crossbow and is unable to fight! The only way to keep Qi Yueling's command is to send the Eighth Legion to block it and create an opportunity for the Sixth Legion to attack...... In a newly formed legion, the combat effectiveness of the soldiers can be imagined, and the casualties are too large, and the Marquis of Dingbei cannot escape the blame! This is simply giving us the position of the commander of the legion!" The young man also laughed.

"A few of our ancestors have already spoken, and they will mobilize a part of the hidden forces and hand them over to your commander, and go to Linshui City! Once the Eighth Legion is defeated, you will take advantage of the situation to attack, and you must fight beautifully, so as to establish your position in the army. Yuan Xixuan said worry-free.

Fang Wuwu was just about to respond, but Yuan Hao interjected: "Father, there is a chariot and crossbow in the Tongyu Kingdom, and Brother Wuwu will lead people to attack, will it ......?"

Fang Wuwu smiled, waved his hand and said: "Don't worry, the other party defeated the Eighth Legion, it is the time to be proud, we will ambush in advance and surprise the other party, we can catch him off guard...... Although the chariot machine crossbow is powerful, it is at a long range, and the maneuver is not flexible enough! We rush into the melee by surprise, and without giving them a chance to open the distance, their weapons will be useless. ”

"I see!" Yuan Hao smiled and said, "Brother Wuwu is powerful, militarily, I am far inferior to you!"

"Yuan Hao, you are not bad, we will be closer in the future!"

Then, a big laugh came from the aristocratic management center......

As the days passed, it was the middle of July, and the weather was getting hotter and hotter, and the humidity in the air was getting higher and higher, making people feel like they were in a steamer, and the whole body was uncomfortable.

The officers and men of the Sixth Army Corps were even more so, their spirits were highly exuberant every day, and under the scorching sun, they had to keep an eye on each other, and they could not relax at all.

The Legion Tent, Wei Ning and the Golden Armor Great Han are still studying each other's motives, for so many days, the other party has come to harass every day, but there are very few real attacks.

There has been nothing for so many days, and they can't help but wonder how far the other party has detoured, and there has been no movement for so long.

"Report!" The voice of the pro-soldier suddenly came from outside the tent: "Commander, commander, the other party seems to have begun to transfer troops!"

"Oh!" the two men stood up at the same time, walked out of the tent side by side, and followed their soldiers to the head of the city, and looked out.

From a distance, the opponent's military camp is no different, but if you look closely, the opponent's chariot machine crossbow seems to be less, although there are not many of them, but those who have a heart can definitely see it!

"Have they found a detour route?" Wei Ning frowned, muttered for a while, and ordered: "Dispatch 30,000 people, search along both sides of the station, once you find the other party's roundabout troops, you have to restrain me desperately!"

After a deputy corps commander was ordered to leave, Wei Ning said again: "Quickly send a letter to the military headquarters and urge the Eighth Army to come as soon as possible!"

After speaking, Wei Ning let out a long sigh, glanced at the golden-armored man, and said in a deep voice: "It's time for a life and death showdown!"

"Hmm!" the golden-armored man nodded, "Once the Eighth Legion is defeated, we must go out to face their chariot machine crossbow......"

Sighing, Dahan said: "The marshal sent a letter saying that Jiang Xingchen would arrive in half a month! Commander, it's been half a month now, it seems that he can't catch up!"

Wei Ning shook his head slowly, did not answer, stared at the enemy military camp in the distance, his expression became more and more solemn.

"Report~" Suddenly, a loud shout broke the silence on the city wall, and the soldiers ran up again, with an unconcealable smile on their faces, and said loudly: "Commander, Lord Commander, Viscount Jiang Xingchen has arrived, and now your big tent is waiting for you!"

"It's here!" Wei Ning's eyes instantly flashed with two substantial lights, and he greeted the golden-armored man and walked down the city wall quickly......

The golden-armored man is the commander of the Praetorian Guard, and he is also a marquis, although he is only in charge of 10,000 people, but he is the ace army of the empire, and his status is not lower than Wei Ning.

Jiang Xingchen was introduced by Wei Ning, of course, he didn't dare to slack off, and immediately saluted.

Although it was the first time the commander had seen Jiang Xingchen, his name was about to grind his ears out of a cocoon.

"If he hadn't seen it with his own eyes, who would have thought that Jiang Xingchen would actually be a young man who had just turned eighteen...... There is no cultivation, no family, but it is unimagin......able to come to this point in a year and a half," the golden armor man sighed in his heart.

But Wei Ning didn't have any other thoughts, grabbed Jiang Xingchen, and asked anxiously: "Brother, how is it, what method has you come up with, what do you need us to do?"

Jiang Xingchen smiled slightly, and said quietly: "Big brother, you immediately organize the officers and soldiers now, let's attack!"

"What!, to face their chariot crossbows?" Wei Ning and the Commander exclaimed at the same time, their eyes widened in disbelief......!
