Fortunately, in this war, the Western Turks did not slaughter the city or plunder the people, but only took away the goods in the various cities and offices of Gaochang and killed some stubborn officers and soldiers, so the battle losses of the Tang Dynasty were only 3,000 people.

The disadvantage of frequent regime changes is that the people have no sense of belonging, of course, if the Western Turks broke the city and killed people and looted everywhere, it would be another matter, but they rarely did not move.

After experiencing this incident, the Tang Dynasty directly fought with the Western Turks, and the vigilance against the Western Turks was directly mentioned to the highest.

Now it is different, Li Daozong was sent back to Shuofang by Emperor Li Er to preside over the finishing of the wool, Duan Zhixuan was left in Gaochang, and 30,000 troops were stationed in Gaochang.

Li Yuanba and others returned to Chang'an with an army of 30,000.

As for why Shuofang needs to be finished, the reason is that the wool plan has been completed, and Shuofang is no longer a wool trading place.

At the beginning, the wool trading base was established because of the split plan of sheep eating people, but now it is good, the Eastern Turks on the grassland have been exterminated, and the population territory has been returned to the Tang Dynasty, and only the Western Turks and Hui are left on the grassland who can trade wool with the Tang Dynasty.

But unfortunately, because of the incident of Zhongnan Academy, Hui Hui and the Tang Dynasty are at odds, and the Western Turks are now also directly at war, breaking up the two countries, and Bai Fan has begun to suppress them with a trade war, so there is no need to do business with them at all, and the plan of sheep eating people is over.

In the next step, Datang will establish a number of wool processing bases in the Eastern Turkic steppe, which can not only save costs, but also enhance Datang's control over the grassland area.

Not long ago, the new emperor of the Wa Kingdom sent envoys to make friends with the Tang Dynasty and discuss the export of labor.

It just so happens that you can consume your strength without fighting, and Datang can't ask for it, so a large number of laborers are recruited from the two roads of the Wa Kingdom every month, and they are transported to the Qinling Mountains to invest in the great cause of opening mountains and building roads.

And Bai Fan, as the deputy chief engineer of Shu Dao, had already followed Li Chun and Li Chengxun to the periphery of Qinling Mountain in the southwest of Chang'an at this time to witness the first sound of Shu Dao.

Chang'an into Shu, originally walked through the Qinling Mountains of the six plank roads, are the crystallization of the wisdom of the ancients, in the mountain wall to dig holes, insert solid stone strips inside, or all with stone strips, or between the two stone strips connected on the trestle bridge, in short, these plank roads are suspended and set up, connected together is a whole road through the mountain.

The advantage of this is that it is built, much simpler than the big road on the ground, but the disadvantage is dangerous, some plank roads are three feet five feet above the ground, just to avoid some creeks below, but some plank roads are built on the cliffs because they want to keep the level, and the conditions are simple, there are no railings or the like at all, the people of the past generations have taken a trip to Shu Road, all like a ghost gate pass as thrilling.

Now Bai Fan has brought Datang black technology, gunpowder has been preliminarily produced and matured over the years, and it is not a problem to open mountains and crack stones, and even a simple version of the shield machine is available, plus huge financial resources and cheap manpower, it is not a problem to repair through the Qinling Mountains in ten years.

This day is the first day of the construction of Shu Road, at the foot of the mountain, Li Chengxun's expression is serious, his palms are sweaty, behind him are Bai Fan and Li Chun, behind him is a group of engineers and technicians, as well as the elite children of the Cui family and the Lu family.

Everyone looked at the mountain in front of them solemnly, and with Li Chengxun saluted the tablet on the table in front of him, worshiped the blessing of the mountain god, and opened the mountain and built the road just to survive, and would not wantonly destroy nature.

Li Chengxun was elected as the chief engineer of Shu Dao, presided over the groundbreaking ceremony, and his status surpassed his two teachers, this is Li Chun's mouth, he is old, Bai Fan has a lot of miscellaneous things, this time he can only rely on Li Chengxun to cultivate Shu Dao, the old man wants to achieve the reputation of his apprentice, Bai Fan is also happy, after all, he is also his own apprentice.

After respectfully worshipping the mountain god, Li Chengdao gave an order and exploded.

I saw an engineer next to him press the detonator in his hand, and then an explosion sounded from the mountain in front of everyone, and everyone felt that the mountain shook under their feet.

Looking at the mountain in front of you, it is as if it has been split by a sharp blade, and large stones are flying and rolling down the mountain, which is not spectacular.

Wow!

The audience was shocked in an instant, the engineering and technical personnel all jumped up excitedly, we succeeded, the ability to open the mountain and crack the stone, the mountain was split, as long as the gravel was cleaned up, there is space to pave the road, with this ability, instead of manpower to dig the mountain, Shu Road will no longer be difficult.

The most shocking thing was the 20,000 laborers of the Japanese country, the first reaction when they saw this scene was not excitement, but fear, and they fell to the ground with a bang at the first time.

The riot broke out in an instant, if it weren't for the guards of the Datang officers and soldiers next to them, I'm afraid that these people would have dispersed in a hurry.

Dugu Xiude, who led the guards, saw this scene and scolded: "A group of soft eggs, opening a mountain will make you scared like this, and I don't know if I can point to you to build roads." ”

He had forgotten that if he hadn't been on a horse, he would have been weakened by the sound.

Bai Fan really attaches great importance to his apprentice, the black technology battery ignition technology, even the Datang military department has not arrived, but he has not cared about using it to repair the road for the apprentice, you must know that the thunder used in the Tang Dynasty siege is still in the form of an ironclad car and a lead.

In order to split this not high mountain, there are a lot of explosives buried in the first mountain, from the top of the mountain to the foot of the mountain, open a hole one meter, bury the thunder, and encounter more difficult projects in the future, and the human ignition will be very dangerous, so Bai Fan ordered people to study the battery ignition technology early, which is not a profound thing, but the production process of various parts is cumbersome.

Knowing that the Tang Dynasty entered Shutian Road to start construction, Li Er wanted to come to join in the fun, but he couldn't get out of it because of his busy affairs, but Li Jiancheng and Li Yuan didn't want to miss it, Li Jiancheng wanted to see his son make contributions, and the old man Li Yuan purely loved to join in the fun.

Seeing his grandson's order, even the mountain was split, Li Yuan couldn't stop laughing, and then he was overjoyed and ordered someone to take the pen, ink, paper, and inkstone, and with a wave of his hand, the four big characters were completely natural - the stone broke the earth!

Although it is not as outstanding as the handwriting of Bai Fan and others, after all, it is a generation of emperors, and he has a feeling to respond to the situation, and he also has a momentum, the old man is full of ambition, and directly ordered someone to engrave his handwriting on the current smooth stone wall.

Bai Fan looked at it and grinned, such a good opportunity, how could the old man pretend to be forced perfectly, it was a mistake, it was too a mistake.

The groundbreaking ceremony was successfully completed, and the next step is to really start building the road, the Datang cement road project is very mature, although the quality of the cement is not high enough, but it can't bear the Datang people, and the cement output is sufficient!

What is the cheapest in this decade? It is undoubtedly artificial, as long as you manage the rice, you can attract people, it is conceivable that once the cement is released from production, how much can it produce?

In less than two years, all the road surfaces in Datang Chang'an City have been hardened, and the roads from Chang'an to Yaozhou, Lantian and Chang'an County have all been paved with cement.

However, this time Shu Road is different, it is the workers of the Wa State, and the first day of the explosives is complete, but the Wa workers have dropped the chain.
