The rough prefabricated fragmented iron shell has been stuffed with more than ten catties of granular gunpowder; Then stuff a section of more than 50 centimeters of nitrate hemp rope into the reserved lead opening.

Test, this fuse should be left as long as possible, so as not to explode at one point, and you can't run away.

After the lead is placed, make some gel to smear the gap between the lead mouth, and an improved official version of the divine thunder will be roughly formed.

The test thunder was still in the Shenren Fang, and he was about to let people dig a pit and bury the mine, when suddenly a forbidden soldier asked a question: "King Shenxiao, how should we make this divine thunder detonate in the enemy formation?" It is impossible to bury the military formation in advance every time it is fought against the enemy. ”

This problem is very constructive, and if the mines that need to be ignited are only used to play mine warfare, it is really inconvenient and has great limitations; Because you don't know where the enemy will come from.

Moreover, if it is buried in advance, the gunpowder is easy to get damp after a long time; Wait until the enemy charges and ignites, as the lead can be easily trampled on or broken.

Even if it is blown up twice by chance, it is easy for the enemy to notice the danger from under his feet, and the place where the mine is buried is easy to find, as long as it is avoided, the divine thunder will have no effect. It may even be captured by the enemy.

"You can light it and throw it out!" The sergeants who practice heroic external skills are quite strong, and it is no problem to throw dozens of catties; Although the iron-shelled mine is full of weight, plus more than ten catties of gunpowder filled inside, the weight is about to exceed twenty catties; But it hasn't reached the point where it can't be thrown. The only trouble is that this tin can is too big, it's really hard to throw away, and you need to make a handle.

Another old craftsman said: "Such a divine thunder, when it is ignited in advance, throw it with a trebuchet, and cause it to fall into the enemy line and explode to injure the enemy." ”

Use a trebuchet to throw it, be creative. The forbidden soldier who asked the question also had a light in his eyes and said, "There is a trebuchet in the workshop, you can try it." ”

Then a rudimentary manpower trebuchet was carried out, if Ye Jinyu was a person who knew a little about cold weapons and equipment, he could put forward a lot of suggestions for improving this kind of trebuchet, such as adding counterweights, or twisting ropes, adding winches, pulleys, etc., to improve the power of this trebuchet.

But he didn't understand, so he could only watch the craftsmen and sergeants operate.

The trebuchet was quickly arranged, and the sergeant placed the iron-clad mine in the leather nest; Please ask the man of God if he can light a fire. Ye Jinyu nodded confusedly, and then the fuse was ignited, and the craftsman did not dare to delay and immediately buckled the mechanism, and the iron-shelled thunder was thrown out by the cannon tip with a long lead.

Seeing that the iron-shelled thunder flew out of the god-man workshop over the wall of the workshop, Ye Jinyu came back to his senses and shouted: "Oops, quickly find the divine thunder and tear off the lead, otherwise it will kill people." ”

The sergeants and craftsmen who tested the god thunder were shocked to realize that they had caused a catastrophe, and hurriedly notified the guards of the Shenren Workshop to go and look for it. It's just that during the test, it was deep in the workshop, and if you wanted to get out of the workshop, you had to bypass the long wall and go out through the gate; There was a lot of time lost on the way.

Ye Jinyu could only hope that the twine lead would not burn too quickly, and that he would find the thunder before it was detonated to remove the danger.

When Ye Jinyu was leading people to find the new bomb that had been lost, in the palace, the new day of the morning dynasty had not yet ended, and the courtiers had been struggling around two topics;

The first is the topic of moving the capital.

Moving the capital is a major matter related to the community, and you can't do it at leisure; It's just that Chang'an is located in the west of the Central Plains, and is deeply threatened by the Turks from the west and north.

When the Turks first emerged, it coincided with the period of division and turmoil between the Five Hu and Sixteen Kingdoms and the Northern and Southern Dynasties in the Central Plains. The absence of a strong unified dynasty in the Central Plains made the farming peoples unable to resist the powerful and arrogant Turks, and the barbarians constantly invaded the Central Plains civilization and plundered the rich population. This continued until the Sui Dynasty unified the Central Plains.

Emperor Wen of Sui Emperor Yang Jian is a very powerful person, in the face of the Turkic invasion, he suppressed all the voices of compromise and retreat, led the army to resist resolutely, and finally repelled the attack of the Turks. Success led to the Turkic infighting and the division into two parts, East and West. The Western Turks are west of the Altai Mountains, while the Eastern Turks control a vast area stretching from the Khing'an Mountains in the east to the Altai Mountains in the west; The two are hostile to each other. The success of the Central Plains and the Turkic strategic situation has fundamentally changed.

However, after Yang Jian's death, the famous second-generation Yang Guang succeeded to the throne, and the great Sui was defeated; The advantage of the Central Plains over the Turks was again reversed. When Emperor Yang of Sui was still in power, he was besieged by the Turks in Yanmen during his northern tour. Among the heroes at the end of the Sui Dynasty, many northern separatist forces often cited the Turks as foreign aid, and most of them called them vassals, and Li Yuan and Li Shimin also asked the Eastern Turks for help when they raised their troops.

After the Tang Dynasty was established and reunified the whole country, the Turks, who could once be relied on, became the predators of the interests of the new empire, and the rulers of the Tang Empire were eager to get rid of them.

The Turkic khans also found that the unified Central Plains was difficult to control and could not extort money from the various separatists as before, so they took advantage of the fact that the Tang Dynasty's national strength was not very strong at this time, and they continued to harass the interior and plunder the population and wealth.

After several conflicts, the Turkic front had seriously threatened the political center of the vast empire. Therefore, the matter of moving the capital has always been in the market of the Tang Dynasty. This time the Turks invaded again, and the matter was raised again.

"The west of Fuxiang Deng, Yi spread for hundreds of miles, its Eastern Han Dynasty, Fenglin is the pass, the south Jutan is bent, and the flow belongs to the Han. There is the danger of Shangluo heavy mountain in the west, there is white cliff contact in the north, it is the place of shape and beauty, the ruins of fertile Yan, if the wide dredging canal, the wealth of the world, can make a large set. Only Xiang Deng, the real Central Plains, the people's hearts are good, go to Qin at hand, and there is Shangluo for the limit, there will never be the risk of Yi Di invading the Yi, this is the best choice for the capital. Your Majesty, Yuanzhou, Lingzhou, and Jingzhou have been lost, and Qinzhou, Longzhou, and Weizhou are in danger; The Turkic soldiers are approaching at night, and Chang'an City is in danger. It is better to avoid its edge for the time being and retreat to Xiangdeng. ”

This is to encourage the relocation of the capital, for the simple reason that Chang'an City is too dangerous.

Earlier, Li Yuan was actually a little inclined to move the capital, after all, the national capital was often exposed to the enemy's iron hooves, which was very dangerous; Moreover, due to the civil strife in the Central Plains for many years, as well as the war with the Turks for many years, Longxi and northern Shaanxi have been sparsely populated. Without a sufficient population base, the Tang Dynasty's control over these places was relatively weak, and because Longxi and other places had been under the Turkic invasion for a long time, the people everywhere on the border were difficult to cultivate, and their lives were extremely difficult. Forcibly controlling these areas in his hands will cost the Tang Dynasty's national strength.

It is better to jump out of this mud pit, first move the capital to Fan Deng, and change Chang'an to the capital of the palace; In addition, the population of the conflict zone will be moved into the Kanto region, and the Kanto region will be developed by implementing land equalization. After the Tang Dynasty overcame the current difficulties and the national strength increased, it came to settle accounts with the Turks.

In the past, such proposals were always quickly rejected; Because the Guanlong area is the place where the military generals and nobles represented by Li Valve and the Guanlong landlord clan started out, the family interests of many officials in the DPRK and Central Ministers are concentrated in the Guanlong area; Giving up this piece is equivalent to asking these important ministers to give up their belongings and take away people's wealth, just like killing their parents, how difficult is it to make these people give up their own interests? As a result, these gatekeeper forces easily got together and jointly elected Li Shimin, the king of Qin, as their spokesperson to oppose the relocation of the capital.

Both sides argued on the basis of reason, and the discussion of moving the capital was always unresolved in the end.

But today the situation suddenly changed, because the pillars of the Guanlong group fell.

Due to the appearance of Ye Jinyu, things have taken a turn for the worse, and Li Shimin, the king of Qin, has decided to go to Muzhou.

This destroyed the plan of the Guanlong group, the King of Qin could go to Muzhou, but the nobles of Guanlong could not, and it was impossible for the vast majority of people to go with the King of Qin, so these nobles were no longer the objects that Li Shimin had to woo. In this way, there is no need for him to risk offending the Son of Heaven and the crown prince to endorse these landlords and scholars, without the heir of the emperor like Li Er as a powerful helmsman, the big ship of the Guanlong Group suddenly lost its direction.

Just as the voices of those advocating the relocation of the capital were rising, Li Yuan suddenly stopped.

"The matter of Xiangdeng is put on hold for the time being;"

Although the capital of Chang'an has some drawbacks, even if the capital is to be moved, it cannot be moved when the enemy's soldiers are in the city, which will deal a heavy blow to the morale of the military and civilians of the whole country. And it was originally because the emperor was not safe that there was a discussion of moving the capital; And today, the séance Yu Chang'an created a divine thunder for the Tang Dynasty, which gave Li Yuan a lot of confidence and made him feel that Chang'an was not so difficult to defend. As a result, his interest in moving the capital plummeted.

"Regardless of whether the capital is moved or not, the internal security must be taken out first, and the Turkic troubles are not appeased, and it is not feasible to move the capital. It is better to discuss how to retreat from the enemy. ”

As soon as Li Yuan's words fell, Xiao Yu, the Duke of Song Guogong, who was still wrapped in a white cloth on his head, stood up and said, "The minister thinks that the King of Qin should fight with the Tiance Mansion; "Xiao Yu is a representative figure of the Guanlong Group and one of the main forces opposing the relocation of the capital; Now that he heard that Li Yuan had no intention of moving the capital, he immediately took over the conversation and tilted the building of the early dynasty; This is the second topic of the early dynasty, who will fight the Turks.

Xiao Yu proposed that King Qin go to war, in fact, he also wanted to keep King Qin in the position of the spokesperson of the Guanlong Group; However, King Qin, who was the person concerned, was sitting there with his eyes and nose and nose and heart, as if what Xiao Yu said was not him.

In fact, at this time, Chang'an City was not without soldiers and horses, on the contrary, because of Li Yuan's small actions, many elite soldiers and strong generals gathered around Chang'an City; It's just that King Qin's Tiance army has not yet left Luoyang, and Li Yuan does not dare to act rashly.

As for Xiao Yu's proposal, it didn't hit Li Yuan's heart at all. King Qin's credit is already big enough, and it is a bit unreasonable to say that he is about to go to Guomuzhou, and let him save Datang from danger.

The emperor actually wanted the prince to lead the army, so as to strengthen the prince's voice in the military, but the Turks were menacing with the power of the country, and they were worried that the prince would lose the battle; Stealing chickens is not a joke; It's a bit of a dilemma!

Fortunately, there are still people in the court who understand, and someone said: "The minister recommended the prince, and the prince, as the prince, should share the worries for His Majesty, and should lead the army out of Longxi and attack the Turkic army......

Before this person finished speaking, he heard a loud thunderclap, and Li Yuan even saw that the pen holder on the desk was shaken.

"What's going on?" "Has the earth dragon turned over?" "The man of God is testing thunder again?" There was a lot of discussion, and the court discussion was interrupted.

Not long after, a eunuch came to report.

"Your Majesty, the king of Shenxiao tried a new type of divine thunder in the Shenren Fang, with the fire rope as the guide, burning, the stone thrower threw more than 30 zhang, fell into the Pingkang Fang, the divine thunder was exploding, destroying three houses, and the wall of the workshop collapsed. Three people died, more than a dozen people were seriously injured, and dozens of people were frightened. King Shenxiao said: "Shenlei can already be finalized, and I will do it according to this in the future, but the fifty centimeter lead is too long, and only half of it is officially finalized." But I can't interview Ray in the city anymore. ””

A divine thunderbolt actually blew up three houses and collapsed two zhang fang walls, which was so powerful; Li Yuan couldn't help but shout three times in a row: "Good, good, good!" The gods and thunders are successful, and everyone in the gods and people are rewarded! Big Prize! ”

Suddenly realized that there were deaths and injuries among the people of the Tang Dynasty, and he said yes, a little unkind, and said with a straight face: "The craftsmen and sergeants in the workshop dare to test thunder in the city, and they should be punished!" All those who participate in the mine test shall be fined for one year. All those who were killed or injured in the explosion of the divine thunder were given generous compensation by the household department. ”

As for the man of God, he deliberately jumped over.

Then he said to the civil and military officials: "I have made a decision, this battle should be led by the prince, with the power of the divine thunder, and the decisive battle against the Turks!" ”

The emperor is bent on making the crown prince meritorious, what else dare others say?

can only shout in unison: "Your Majesty Shengming!" ”

……

The gaze was drawn to the hundreds of miles west of Chang'an City, the plateau in the northwest, and it was bleak and desolate after winter.

On the hillside, several Turkic knights stepped on the fallen leaves and looked into the distance, looking at the dusk sky and the dusk ground in the distance; At their feet, a large group of Turks on horseback roared and galloped past.

The knight at the head asked, "How far are we to reach Longzhou?" ”

The person behind him replied: "There are still more than forty miles of land, and the fast horse can arrive in an hour." ”

The knight at the head asked again: "Where is the Khan?" ”

The man on the right hand said: "The headquarters of the Turki Khan has crossed the Yellow River, and according to the Khan's schedule, it should arrive in Jingzhou at this time; ”

The left-handed man said: "The army of Jieli Khan has passed through Qinzhou and is behind our army. ”

"The Tang army we encountered along the way was like a chicken, and we rushed to the front of the Khan." The knight at the head smiled and said loudly: "Pass the order, hurry up, let's go to Longzhou City for the night!" ”

Although Longzhou City is not a big city, it is relative to an international metropolis like Chang'an; For the Turks, Longzhou was already a good place of wealth and population. If Longzhou is captured, their small tribe will be able to have a good winter.

The words of the head man were heard by some riders, and they all let out excited voices: "Yo ho ......" continued to roar forward like locusts.

They don't know what awaits them ahead.
