This so-called weapon of mass destruction, that is, black powder.

One sulfur, two nitrate, three charcoal, and a little sugar Yin Wan, this can be called a smooth mouth known to women and children in later generations, and it is not surprising that Guo Rong will know this.

In fact, from the beginning of the crossing, when he was still in Qiuzi, Guo Rong once thought of trying to make the simplest version of black powder to help the Anxi army defend the city according to the guidance of Shunkouxi.

However, after trying his best, Guo Rong found that Qiuzi did not have that condition at that time.

Charcoal is also counted, although there are no trees within a hundred miles of Qiuci, but Qiuci City itself also needs to build weapons and ordnance, so charcoal Qiuci is available, but outside of charcoal, sulfur and saltpeter are not easy to find.

In all fairness, normal people would go out with this thing, and the caravan would not take this thing to sell it all over the Western Regions for profit.

There was indeed a caravan willing to buy some sulfur and saltpeter in Guo Xin's face, and promised to bring it to Guo Rong when he returned to Qiuzi next time, but until Guo Rong led the eighth regiment on the road, he did not see the shadow of this caravan.

In the small city of Qiuci, everything is lacking, but in the Tang Dynasty, which is rich in land and resources, all this is not a problem.

With Li Chen's support for Guo Rong, he can get what he wants, and even Guo Rong wants a few R&D personnel who develop black powder.

As a result, under some operation, the Emperor Taishang sent people to find a group of Taoist priests from Longhu Mountain, Wudang Mountain, Qingcheng Mountain, Qiyun Mountain, and Zhongnan Mountain, among which there were many brothers of Zhang Jiaxuan of Longhu Mountain and Zhongnan Mountain.

And, the specialty of these Taoist priests is refining elixir!

After all, these are the only people who often come into contact with things like sulfur and saltpeter, and ordinary people don't touch these things at all.

Zhang Jiaxuan was quite shocked when he saw that his senior brother had also come, and immediately said that his senior brother was extremely deep, and his alchemy technique was even more extreme, and after taking the elixir refined by his senior brother, the chance of ascending increased by at least three percent!

Seeing Guo Rong for the first time, Zhang Jiaxuan's senior brother took out a box from his arms and handed the box to Guo Rong.

At that time, after opening the box, looking at the egg-sized white and shiny lead ball in the box, Guo Rong fell into deep thought, no wonder Zhang Jiaxuan said that after taking his senior brother's elixir, the chance of ascending increased by thirty percent, and thirty percent was too modest.

Just this thing, if you finish eating it, you won't just be promoted to the army......

In this regard, Guo Rong can only say that Zhang Jiaxuan is a good doctor, but his brother is too different, but in a sense, these guys can also be regarded as the earliest chemists in China, and it is indeed best to let these people study it.

Of course, Guo Rong felt that it was more appropriate to call them alchemists.

"The current power of that thing is absolutely no problem to blow up the city wall, and it is absolutely easy to use the mountain gravel!"

The other party's words were light, but when they heard Guo Rong's ears, they brought a huge shock to Guo Rong.

"Cheng Qian, are you ready to put into actual combat?"

"Of course, the big stone we saw on the road today, there should be more than a dozen catties that should be able to be blown up, at least it is definitely easier than them burning stones now, that is, we must pay attention to safety when using it, but if there is an accident, the explosion or broken gravel will kill a person and play with it."

"......"

"General, it's just that we don't have much stock, and if we want to help them build roads and open mountains, we must transfer materials from outside, so ......"

These few words, others were dizzy when they heard them, but Guo Rong knew what Cheng Qian was worried about, which was why Guo Rong named this thing the Great Killer.

Gunpowder is indeed a good thing, if it is in Qiuzi, Guo Rong will not hesitate to put black powder into actual combat, but now, Guo Rong also knows that once, in the era of cold weapons, as long as he does not have civil strife, Datang is an invincible existence, and black powder is the icing on the cake.

On the contrary, if you rashly put this thing into the military field, there may not be some changes that are beyond your control, and if any variables arise, you will regret it.

It's just that in the next moment, Guo Rong suddenly remembered that the original role of explosives seemed to be to open mountains and roads, and open mines, which could be regarded as a return to the origin, and the most troublesome thing for Cheng Qian before them was to experiment with the power of black powder.

In this case, it is better to justify the construction of the road as a testing ground for black powder, but it is ......

"The road from Fugu to Chang'an is of great significance to my Tang Dynasty economy and people's livelihood, we are Tang people, and it is naturally incumbent on us, Xiao Wu, you take others to sort out the things that can be provided to Mao Yunpeng, and then hurry up to teach them to Mao Yunpeng's Ministry of Industry and the craftsmen who will be superintendents."

"Obey!"

"Cheng Qian, Gan Jie, Liu Huang, you come with me, some things can't always be hidden, and the ugly daughter-in-law always has to see her in-laws."

Immediately afterwards, Guo Rong left the big tent to Wu Pengjun and a group of craftsmen, and took a few gunpowder experts from the Changying Military Engineer Battalion who were born as Taoist priests to go directly to the big tent of Emperor Li Yu.

"Hey young, I didn't come by myself today!"

"Your Majesty, the minister has an idea, it's about the big killer weapon in the past!"

"Oh, how?"

"The minister wants to use this road repair to comprehensively test the effect of the big killer......

"Who are these?"

"These are Taoist priests who are proficient in alchemy and alchemy that the minister once asked you for, and now they are the ...... of the Changying Army Engineer Battalion."

"Tell me more about ......"

……………………………………………………………………………………

"Peng!"

With a shocking bang, large pieces of rubble scattered throughout the valley.

On a high slope two miles away from the bombing site, Li Yu, Bai Juyi, Liu Yuxi and other personnel who watched the current situation of the blasting under the protection of a whole row of tower shields were shocked.

Immediately after that, the sound of "clanging" came to the ears of those present, and even two miles away, there was still a small amount of gravel and mud hitting the shield.

Compared with these relatively weak civil officials and the weak emperor, Guo Rong, Cheng Qian, Mao Yunpeng and others walked out of the hiding place as soon as the blasting was completed.

After several people rushed to the explosion point, they found that the protruding boulder that had been in the middle of the mountain road had disappeared, leaving a pit at least three feet deep where the boulder was located.

Looking at the disappearing boulders and the deep pits left behind, Mao Yunpeng, who presided over the construction of the road, was in a state of extreme shock.

Two days ago, when his former friend Wu Pengjun of the Ministry of Industry led a group of engineers from the Changying Army to teach him and his craftsmen the knowledge and methods of various projects and equipment, Mao Yunpeng had been deeply shocked.

When he was sure that the techniques he had mastered from the Mo family were outdated, he felt an indescribable sense of frustration.

If at that time, Mao Yunpeng had a sense of frustration, then at this moment, Mao Yunpeng has a huge sense of crisis, and these are all he masters, and these are the ones who are based on the world......

Of course, if Guo Rong is asked to evaluate Mao Yunpeng's state, Guo Rong will tell Mao Yunpeng a noun, dimensionality reduction strike, after all, it may not be his peers who kill the road builders, but they may also play explosives.

Compared with the shocked Mao Yunpeng, Cheng Qian and several other guys were affectionate and extremely excited.

"Head, it seems that the amount used this time is too large, and the power is excessive."

Cheng Qian's words, Guo Rong knew that his idea was right.

In a sense, scientific research is a stroke of luck, and the actual use of explosives is definitely more valuable than so-called laboratory tests.

This time it's too powerful, and the next time it may not be enough, but a few more times, these guys will definitely become real experts.

At the same time, on the slope of the capital two miles away, when the smoke of gunpowder dissipated, Li Yu took out his clairvoyant mirror and looked carefully at the ruins after the explosion, and after seeing the current situation of the explosion site clearly, Li Yu couldn't help but sigh.

"The big killer is really a big killer, Guo Rong can always bring good things, this posture, even the city wall of Chang'an can't withstand such a blow!"

Although it was said that Chang'an couldn't hold it, the slightly trembling body and the extremely bright smile on the corner of his mouth proved that Li Yu's mood was extremely good.

In his heart, Li Yu thought that maybe the imperial court of the Tang Dynasty should be expanded again, and maybe a new firearms supervisor or ordnance supervisor should be established......

According to the original plan, it would take about three to four months to return to Chang'an from Fengzhou.

However, the road conditions from Fugu to Chang'an far exceeded expectations, and although it took a lot of time to provide assistance to the army of road repairers and help the army clear obstacles, the return time was still faster than expected.

In March of the third year of Yuanhe, after two and a half years, the forbidden army led by Guo Rong finally returned to Chang'an.

On that day, under the warm winter sun, the emperor Li Chun, who stayed in Chang'an, led hundreds of civil and military officials, and the people of Chang'an went out of the city for ten miles to greet him.

On this day, the red flag is displayed, the crowd is crowded, it is the day, the mountain is calling for a tsunami, long live like a mountain.

Looking at the emperor and the emperor who are filial to his father and son, and looking at the people of Chang'an who are surging with mountains and tsunamis and passion, Guo Rong suddenly has a very special feeling.

Compared with before, Chang'an is still the same Chang'an, but it is not simply the former Chang'an, as if Chang'an at this time has finally recovered from the continuous war and turmoil, and has restored its former bearing and self-confidence.

After completing the task, bringing the Changying Army and other parts of the forbidden army back to the forbidden army camp in the forbidden garden, and settling the soldiers who had been mixed all the way to the Dutian German Army and the Pinglu Army, Li Yu was very considerate and gave Guo Rong a long vacation for half a month.

Returning to the eldest princess's mansion, seeing a wife and a concubine, and seeing a pair of children, Guo Rong sighed with emotion.

Especially a pair of children, when they set off, they were still in swaddling clothes, and after returning to Chang'an, they have learned to walk, and they have a sense of being separated from the world.

The holiday that Guo Rong got can be regarded as a convention of the Tang Dynasty, and it is also the glory of the general who returned triumphantly, and under normal circumstances, it can be regarded as Li Tang's reward for the general who returned to the victory.

Guo Rong can rest, but it doesn't mean that others are the same.

First of all, the emperor was not idle.

After completing the welcome ceremony, the Emperor Taishang only rested in Xingqing Palace for less than a day, and immediately devoted himself to the cause of the revival of the Tang Dynasty.

First of all, the emperor Li Chun was convened in Xingqing Palace, and the elders of the three provinces, seven departments, nine temples, seven prisons, and one were held at a very high level.

Then he began to summon all the important civil and military forces who stayed in Chang'an to understand the progress of various undertakings he cared about.

The Ministry of War, the Ministry of Households, and other related government offices are also operating at full capacity.

Although the military exploits of the various departments of the forbidden army have been counted on the way to the march, after returning, it is still necessary to carry out the final statistics and accounting of the military exploits of the forbidden army, and determine the titles, titles, rewards, and so on.

Then there are busy civilian officials of the forbidden army led by Han Yu, Liu Yuxi and others.

During the protracted expedition, the establishment of the forbidden army has undergone several changes and has experienced many wars, and it is urgent to fill the gap and restore the establishment.

At the same time, the forbidden army left Chang'an for two and a half years, and after batch after batch of recruits passed the assessment, they became reserve soldiers and auxiliaries of the forbidden army.

Half a month passed in a flash, and the entire Chang'an City, including Guo Rong, was spent in a tense and busy process.

After fighting hard for half a month, after suppressing the two card friends as a landlord, Guo Rong received a request from Li Yu, three days later, he needed to participate in the Wangri Dynasty meeting, if he didn't understand, let him go to Han Yu to make up for the class.

was designated to attend the court meeting three days later, and when he heard this request, Guo Rong was very confused, after all, to be honest, he had not participated in the court meeting until now......

So, Guo Rong rushed to the camp of Changyingjun as soon as he received Li Yu's request, but after Han Yu's make-up class, Guo Rong suddenly found that the court meeting in the Tang Dynasty was still so exquisite, and it was completely different from the court meeting on the TV series he had seen before.

In ancient China, it was called the court when the minister saw the king, and the king saw the minister as the meeting, which was collectively called the court meeting.

The most important court meeting in the Tang Dynasty was the New Year's Day and Winter Solstice Dynasty held once a year, followed by the Shuowang Day Dynasty held on the first and fifteenth day of the first day of the first month at the beginning of the Taizong Dynasty and the Xuanzong era.

However, whether it is a large court meeting or a Shuowang day court meeting, it is more of a ceremonial court meeting, and under normal circumstances, it mainly summarizes the plan, announces the edict, and announces the reward, but does not do things, and the meeting does not discuss.

And Guo Rong or the early dynasty shown in later TV dramas is the third type, Chang Dynasty, Chang Dynasty is also called Chang Shen, or Japanese Dynasty, Early Dynasty.

And the Chang Shen presided over by the emperor himself was the meeting where the emperor really discussed major matters with the important ministers of the imperial court and the Zaifu. It's just that there is the Tang generation, and Chang Shen has never been strictly enforced.

In the thirteenth year of Taizong's Zhenguan (639), Fang Xuanling asked for three days and one dynasty, and in the twenty-third year of Zhenguan (649), the eldest grandson Wuji and others asked for "seeing the dynasty and sitting on the day".

In the second year of Gaozong Yonghui (651), it was changed to "Five Days and One Dynasty".

When Wu Zetian was in the day, he "had a dynasty every ten days".

After Zhongzong ascended the throne, he ordered "not to sit every other day".

In Xuanzong's later years, the government was wasted, and the system of Shuowang Japan and Dynasty was destroyed, and the Chang Dynasty was even more useless.

What Li Yu asked Guo Rong to attend was the Shuo Ri Dynasty Meeting held on March 15.

"The Emperor Taishang is going to officially announce the forbidden army to the world this time!"

Listening to Han Yu's exclamation after introducing the court meeting, Guo Rong was confused.

"Mr. Retreat, what does it mean to tell the world? Hasn't the forbidden army been known to the world for a long time? ”

"You!" Han Yu smiled and pointed at Guo Rong and scolded with a smile, "Stupid! ”

"It will not be discussed, and it will not be discussed, so what do you think can be done at the court meeting?"

"Reward?"

"It's still saved, the battle of Longxi and Longnan is more than enough for you to be a marquis, but Your Majesty only gives you a reward, and no title, I felt very strange at the time, I thought you would be dissatisfied, but you didn't have any complaints, it's not easy, I'm afraid that another person will be dissatisfied for a long time, and only you will honestly lead the troops, lead the troops, and train the troops for Your Majesty."

"Forehead ......"

To be honest, Guo Rong really didn't think about it so much.

"Your Majesty didn't knight you at that time, in my opinion, the first is to continue to test you."

"Anxi Army?"

"Yes, with Your Majesty's high expectations for you, after all, if one day you have a different heart, the harm will definitely be more terrifying than the former An Lushan, no matter how many tests there are, it will not be strange."

Seeing that Guo Rong nodded, Han Yu gave a teachable look and continued.

"As for the second point, considering such a big victory in Longxi, Your Majesty did not carry out large-scale propaganda, but began to expand the forbidden army on a large scale, I speculate that Your Majesty hopes to maintain Taoguang before he has enough hard power, and at the same time let the suspicious people jump out on their own."

"Now it seems that you have completely passed Your Majesty's assessment, and Your Majesty has enough confidence in the combat effectiveness of the forbidden army, Feng Tang is easy to be old, and Li Guang is difficult to seal, so you kid has come out, prepare well, don't be rude at the court meeting."

"Your Majesty asked you to come to me?"

"Oh, I see."

"What!"

"If I'm not mistaken, the Great Dynasty Meeting, the Shuowang Dynasty Meeting, and the Chang Shen Festival, you haven't participated in it once."

"Yes! I thought ......"

"Your Majesty is asking me to train you in etiquette, hurry up, there are only three ......, and after three days, you are the card that Your Majesty wants to show to the ministers and the world!"

Then, Guo Rong was directly imprisoned by Han Yu in the camp of the Changying Army......

Everything was just like Han Yu's speculation, and three days later, the court meeting became a stage for the forbidden army led by the Changying army.

The countless rewards, like a tsunami, shocked all the courtiers who participated in the court.

Including Guo Rong, Li Rui, Zhang Yiyi, Shao Shumin and other generals of the forbidden army were all made marquis, although no one was crowned duke, but more than a dozen marquis who belonged to the forbidden army still shocked the world.

Overnight, the forbidden army of the Tang Dynasty became the most important noble force in the world.

Among them, Guo Rong was awarded Jiuquan, Li Rui was awarded Zhangye, and Zhang Jieyi was awarded Fulu......

Interested people have noticed that the fiefs of all the generals and colonies of Changying, Yulin, Tiance, and Shenwei are all located in Hexi, that is to say, the next goal of Emperor Taishang is already very clear, that is, Hexi!

Of course, Guo Rong has not only obtained only one Jiuquan, but Guo Rong cannot simply exist as the commander of the forbidden army as before.

Zuo Shilang of the Ministry of War, this is the most important position that Li Yu gave to Guo Rong in addition to the general of the Changying Army, and the purpose of this position is only one point, to facilitate Guo Rong to coordinate the command and reform of the forbidden army - the second round of military reform of the Tang Army.

In addition, Guo Rong's concurrent positions also include education supervisor, science and technology supervisor, and navigation supervisor......
