Lu Su was finally pulled away by Pang Tong.

After all, although there were some speculations before, it is completely different from what you finally saw with your own eyes.

A sailor who bravely broke the waves and swept the north.

The Cao army that competed with it from all directions.

The dark passage of the white clothes on the back of the Koto.

The grandson of the grandson who acted lightly and cunningly.

And with the sighs of later generations, as well as the inconspicuous claim that Sun Quan was sick, etc., Lu Su thought about the hard work he had poured into this Jiangdong, and he became more and more silent.

In the end, Zhang Fei stepped forward and gently patted Lu Su on the shoulder to show relief, and finally left with Pang Tong's insistence.

Seeing Lu Zijing's stumbling back when he left, Kong Ming also shook his head, closed the notebook in his hand and stretched.

The lord took care of Lu Zijing's thoughts, so he left the stage early, which also made the light curtain discussion more casual.

Doctor Zhang left in a hurry, and he should be worried about the bottles and cans in the medical department.

As far as Kong Ming knows, Doctor Zhang has been very busy recently.

Three months ago, medicine was only ranked last among the seven subjects in the imperial examination, and the number of applicants was naturally the lowest.

But in the end, a few manufacturable materials still stood out, which already made Zhang Zhongjing inexplicably excited.

In addition, the distillation method that he heard from later generations and was perfected by the people of the Tang Dynasty also made Zhang Zhongjing fascinated by it, and he couldn't wait to soak in that workshop every day.

Not just Doctor Zhang, Jian Yong is now busy comparing the maps obtained from later generations, and reconstructing the geographical maps west of the Western Regions one by one, preparing for the Han Dynasty's return to the Western Regions to deter Central Asia in the future.

Mi Zhu needs to coordinate the trade exchanges between Jingyi and Jiangdong, and has been frequently sending merchants to the west of Yongliang, determined to dredge the trade routes, so that the Southwest Yi Road can be connected with the Western Regions Trade Road, and expects that after the defeat of the Cao thief in the future, the Southwest Yi Road, the Western Regions Trade Road, the Liaodong Trade Road, and the Nanyang Sea Road will be connected to each other, so that Chang'an Luoyang will live in the middle, so that the so-called "Silk Road" in later generations will live up to its name.

Fa Zheng should have gotten up and gone to Taixue, if you want to redefine the world, you need a new law, Fa Zheng has been busy with this matter in the past six months, not only quoting scriptures, but also looking at the light curtain to try to examine the law of the Tang, Song and Ming dynasties and later generations from just a few words, as a reference, and it seems that Zhong Yuanchang also helped together.

And ...... "What's the matter with Yide?" ”

Kong Ming, who was stretching his waist, looked at Zhang Fei, who was kneeling in front of him in a regular manner, and was a little strange.

Zhang Fei touched the back of his head, but his words were not polite at all:

"Strategist, I'm so curious about that artillery."

Kong Ming is clear.

After all, the people of the Tang Dynasty focused on depicting the power of this thing.

Just need to listen to the Tuguhun that died because of this, which is naturally inevitably curious.

"Just let me go." Kong Ming got up and set up the table and mat, and then led out of the side hall in front.

When the light curtain was broadcast, the soldiers guarding outside the hall had already dispersed without a trace, and the two of them stepped out of the main gate as if they were walking through their own courtyard.

"Ah, it's snowing."

Zhang Fei raised his head and caught the falling snowflakes with his hands, this kind of weather reminded him of Zhuojun after decades of absence.

The snow of Yanshan, I don't know if I can see it tomorrow?

My mind was open for a while, and when I turned around, I saw Kong Ming clumsily getting on the horse wrapped in thick clothes.

Zhang Fei was suddenly anxious:

"Why do military advisors need to ride horses? Let me Lao Zhang drive for the military advisor! ”

The servants of the General's Mansion were no strangers to Zhang Fei Kong Ming, and there was no need for Zhang Fei to go over to tell him, so the groom was very discerning and expressed his willingness to drive for the three generals and military advisors.

"My husband is going to rest!"

Zhang Fei laughed and refused:

"It's been a long time since I've been driving for the military division, so why rob me? Isn't roasting around the hearth in such weather much more comfortable than driving in the wind and snow? ”

Kong Ming, who was forcibly helped into the carriage by Zhang Fei, smiled when he heard this, shook the residual snow on his body while shaking his head in his heart, feeling that Yide was probably thinking about it from a detailed point and felt that the matter of artillery should be hidden.

After Kong Ming sat down, Zhang Fei sat in the wheel and listened to the military advisor's direction, and drove the car in the wind and snow.

"Doesn't Yide feel cold?"

After crossing two streets like this, Kong Ming listened to Yide humming an unknown tune happily over there, and finally couldn't help but ask.

"Compared to Zhuo County, this level is considered warm."

Kong Ming nodded, and in his heart he remembered what later generations said about the longitude and latitude of the earth, the closer to the south, the warmer it is, and the farther north it is, the colder it becomes, but I don't know what such temperature changes have to do with that latitude and longitude?

However, even if Kong Mingxuan is troubled in his heart, he has his own ruler to measure the square inch of things, and he can measure the temperature level, how to make a ruler?

After thinking about it, a few conjectures soon popped up, but they were soon denied by Kong Ming himself, and then Zhang Fei's voice asking for directions interrupted his thoughts.

Over there, Zhang Fei didn't notice the distraction of the military advisor, and was still chattering over there:

"Although Zhuojun is cold, and it can still live, then Changli Xuanxuan in Liaodong is really called cold."

"There is also Wuhuan Hu in northeast Liaoning, where the place to stay can be cold for six months a year."

"When I turn around, I will invite the military division to visit the north, but Zhuojun is too cold, and the military division can go to Zilong's hometown to see.

"If I can return to the north, I will definitely go twice in front of the Lianzijing when the time comes, and see who dares to say that my old Zhang can't make meritorious contributions, and the military advisor must remember to make my old Zhang Junyin bigger."

Kong Ming listened quietly to Yide's chaotic narration, listened to his complaints about the severe cold in the north, and also felt the thoughts of Zhuojun between the lines.

However, hearing the name Lianzijing still made Kong Ming curious, and asked casually:

"The Pull Sutra is the one who aims to settle the people?"

"Who else could there be if it wasn't him?"

Kong Ming is clear.

Recruiting his people, the lord only talked about it after hearing about the defeat of Yiling, and accidentally drank too much, but he only sighed, "Fortunately, the son of the book did not follow me, otherwise it would affect the people of the north." ”

The lord did not deliberately hide it, and later Kong Ming asked curiously, and in a few words, Kong Ming also had a preliminary impression of this lord's friend when he was young.

The good man is determined to fight on the border, and killing Juan Min is enough to comfort his life.

Zhang Fei sighed for a long time, but he didn't get too entangled, and soon told Kong Ming what good fruits there were in the north in the middle of summer, and Kong Ming was a little hungry when he heard it, but fortunately, he quickly followed Zhang Fei's voice:

"Strategist, it's here!"

The carriage stopped, and the snow became heavier.

This is Ju County south of Chang'an, Zhang Fei looked at it across the abundant water, the wind and snow were too big to see anything clearly, but Kong Ming knew what Zhang Fei was looking at, so he also explained:

"Over there, the Meridian Valley."

If there was no light curtain, thirteen years later, when Ji Han did not want to be partial, Wei Wenchang proposed this strategy to seek miraculous achievements to rejuvenate the Han Dynasty, but was vetoed by Prime Minister Zhuge Cheng.

The Meridian Valley conspiracy was said more than once in later generations, and the results of each discussion were difficult to achieve, but he still cared so much, and he was sighing for Ji Han.

Fortunately......

"I see, it's better that this valley doesn't have to march like this."

Zhang Fei stretched his neck and looked hard, but in the end it was fruitless, but finally sighed.

"General Yide hurried in to warm up, why are you sighing here?"

There are not many people in Juxian County today, and when Zhang Fei drove over, he also met a sergeant in the north of the county who was not afraid of the wind and snow, so the owner here also knew that someone was visiting.

Zhang Fei laughed as soon as he turned around, and first bowed his hand to the people who came:

"General Fu."

Then he stretched his neck and smiled at the young man behind Fu Wei:

"Little Jiang Wei, I thought you didn't want to see me in Chang'an, but I didn't expect to be idle here."

Fu Wei nodded, and greeted Zhang Fei and Kong Ming.

Jiang Wei, who looked unusually small in front of Zhang Fei, raised his head unconvinced and said:

"What kind of idleness, I'm busy here, all contribute to Xinghan."

Although there was some speculation in his heart, Zhang Fei couldn't help but tease this junior:

"You haven't grown tall yet, what do you say? Study hard and wait for the future to govern the country and the people. ”

Seeing Jiang Wei jumping to his feet to argue with Zhang Fei, Kong Ming also hurriedly appeased his disciple.

Fu Wei didn't say a word, stretched out his hand and led Kong Ming inside, and Zhang Fei also briefly inquired about the situation here.

Juxian was originally close to Chang'an, so life was okay, but in the case of repeated visits by military thieves, the people quickly died and fled, and when Xiahou Yuan settled in Chang'an and requisitioned the people's husband Tuntian, Juxian was completely deserted.

When Liu Bei returned to Sanqin, some of the people of Juxian County who ran earlier also came back occasionally, but the number was quite scarce after all.

Later, Kong Ming saw that this place was close to mountains and rivers, and the distance from Chang'an was also quite suitable, so he simply compensated the remnants of Juxian County, and then summoned troops to build houses in the county, and transferred craftsmen here to study artifacts.

Zhang Fei couldn't wait: "What about the artillery?" Little Jiang Wei quickly pull it out and give it to me! ”

Kong Ming is much more serious:

"What about Deheng? There are one or two new drawings here, which should be able to solve one or two difficulties in making cannons. ”

Jiang Wei ignored Zhang Fei's words, but when he heard that the master had new drawings, he immediately jumped up and took them.

Hiding under the eaves to avoid the wind and snow staining the ink, Jiang Wei was slightly surprised after opening it carefully: "Wooden cannon? ”

Then he took the drawings and left reflexively, and before leaving, he didn't forget to drop a sentence:

"Master Lao and General Fu will go to the north of the county, I will go to find Senior Brother Ma, and I will go over in a moment."

Looking at Jiang Wei's back, Zhang Fei, who was not mentioned, was not annoyed at all, shook his head and said:

"Little Boyo has a faint talent for taking charge of his own side."

Fu Wei, who was silent, nodded silently, while Kong Ming shook his head and said:

"Far from it."

Zhang Fei looked at Kong Ming's expression, and immediately reacted:

"Senior brother?"

Fu Wei found another winter coat for Kong Ming, and after the three of them crossed Juxian County, they saw Jiang Wei jumping next to a clearing to say hello, and next to him stood a young man with a cold face like a piece of ice, more than two heads taller than Jiang Wei.

Zhang Fei glanced at this "junior brother", and Kong Ming issued orders in an orderly manner.

According to Kong Ming's instructions, a team of guards who were auxiliary at the scene pushed the car covered with tarpaulins on the side, and the wheels left conspicuous ruts on the ground.

So Zhang Fei finally saw the supreme weapon praised by the princes of the Tang Dynasty, which was not very eye-catching.

Jiang Wei retreated, leaving Ma Jun and a few soldiers to stay on the side of the artillery, busy in front and back.

Seeing the obvious look of doubt on Zhang Fei's face, Jiang Wei crossed his waist and declared:

"This thing is worth more than 100 elite soldiers! The three generals are optimistic! ”

Over there, Ma Jun and the others fixed the artillery, stuffed gunpowder and projectiles in turn, and finally Ma Jun hid behind, and with the help of the people next to him, he carefully lit a fuse that poked out from behind.

In the sound of falling snow, the sound of the gunpowder line burning was quite obvious, and Zhang Fei watched as the thin line of fire continued to approach the tail of the artillery, and finally got in.

"Tom!"

There was no earth-shattering sound as expected, dull and quiet, and the sharp-eyed Zhang Fei also saw that the projectile that was stuffed in "flowed" out of the muzzle, smashing on the ground and stirring up a cloud of snow.

Zhang Fei looked at Ma Jun and the others who were busy again, and then his eyes stared at Jiang Wei's face, which made the young man's face suddenly turn red, and he hurriedly defended:

"It must be snowing heavily and wetting the powder!"

Nodding, Zhang Fei said that he accepted this statement.

Soon the work over there was over, and the familiar thin light of fire meandered into the tail of the cannon, and then Zhang Fei saw the light of the fire blooming from the muzzle.

The projectile flew fifty or sixty steps before falling to the ground, and a conspicuous black line appeared in the snow, and the muzzle of the cannon was still emitting thick smoke, which made Ma Jun and the others scatter and flee.

"It must be ......" Jiang Wei was a little short of words for a while, and ushered in Zhang Fei's rather perfunctory nod: "I know." ”

This suddenly made Xiao Jiang Wei angry, I didn't say anything, what do you know?

So Jiang Wei immediately jumped towards the artillery and shouted:

"Senior Brother Ma, the medicine powder I mixed was pressed to the bottom and wrapped in paper!"

Ma Jun acted steadily, and asked Kong Ming loudly for instructions, and received a positive answer.

So the third preparation started, Jiang Wei was full of nervousness and couldn't take his eyes off it, Zhang Fei looked at it with his hands on his chest and didn't care, still guessing how far the projectile could fly this time.

The first thing I saw was a flash of light like the scorching sun exploding at the muzzle of the cannon, and then a voice like Huang Zhong Dalu shook Zhang Fei's head in chaos, and he almost didn't know who he was.

But the eyes faithfully reflected everything they saw:

The dirt and snow on the ground near the muzzle were swept up and scattered into the sky with a strong force, and the boulders in the distance exploded, and several large trees in the woods behind them slowly fell to the side with a creaking sound.

Until a quarter of an hour later, Zhang Fei, who was sitting in the room again and roasting the fire, still had a hard time forgetting the scene he had seen from his mind.

Ma Jun on the side had obvious pity on his face: "The cannon body is cracked."

"The cannon is cast by the lost wax method, two out of ten, and now the two cannons are cracked and cannot be repaired."

This news was not surprising to Kong Ming, he sighed lightly, he also envied the wealth of the Tang Dynasty again, cast cannons by various means and then test-fired, and then sent the uncracked ones to the battlefield, and then improved them according to the final remnants, which can be described as wealthy.

They can't do it at this time, and the financial, material and human resources required for this method are in short supply in Chang'an at this time.

"In that case, let's see if the wooden cannon can be made." Kong Ming explained that Ma Jun had nothing to do.

After explaining the matter, Kong Ming turned to look at Jiang Wei:

"And what's the last powder?"

Jiang Wei didn't dare to hide:

"Previously, a batch of gunpowder was forgotten to be harvested when it was dried, and it could not be used when it was stained with snow."

"I was afraid that the master would punish him, so I removed the water from it, and the gunpowder I got burned more violently......

Kong Ming keenly grasped the loophole and asked:

"There have been no sunny days in Chang'an for nearly half a month, how to remove the moisture?"

Seeing that he couldn't hide it anymore, Jiang Wei had no choice but to whisper:

"...... with charcoal"

Kong Ming gasped in shock, and slapped Jiang Wei's head with a fan to reprimand:

"You really don't know what death is?"
