When Songtsen Gampo was entangled here, Dorjee was also very excited at the moment.

They were finally about to set out, and it took him almost a month to learn, and in that month he had learned a lot, and the gentlemen sent by His Highness had taught them many ways to convey information, and had told them that what they had done was such a great thing.

Now Dorjee feels that he is not the same as he was a month ago, and he now knows exactly what he wants to do and what he wants to do.

He wants to spread the flame of His Highness's ideals throughout Tibet, let His Highness's ideal flame burn among the slaves of Tibet, and burn all those noble slave owners!

It's just that what Dorjee didn't expect was that yesterday, His Royal Highness sent a painter and painted two portraits for all seven of them, that unique black and white portrait is very magical, Dorjee was drawn on a horse, he never thought that there was really a painter who could paint him so like!

This kind of portrait is called a sketch.

The painter painted two paintings in total, one of which was a portrait of him sitting there, which was left to his family, and the other that His Highness said was useful.

Dorjee's body has been changed into the original clothes of Tubo, although Tubo is already very cold, but he must wear these clothes, because in Tubo, this is the clothes worn by slaves, even in winter, every winter slaves will freeze to death.

Fortunately, before arriving in Tibet, he had thick leather clothes to wear.

Dorjee and his family rushed to the meeting place, but to Dorjee's surprise, by the time they arrived, there was already a group of soldiers here, and at least more than a thousand soldiers stood in two rows in a neat line. And all the original Tibetan herdsmen from the villages near them came.

"You are all here, it's okay, Your Highness said, if it goes well, maybe I can come back next year." Dorjee said with a smile.

Despite saying this, Dorjee's family still shed tears, but none of them stopped them. Because during this time, Dorjee came back from studying every day and told them what they had learned and what a great undertaking it was.

They also understood a lot.

"Let's go in a hurry today." Lin Quan walked over and said in a low voice.

Dorjee nodded, then turned over and mounted his horse, and the other six people also turned over on their horses.

"You follow this general, and he will take you to the border." Lin Quan pointed to a captain at the front and said.

"I've seen the general."

"You're welcome, I'm not a general, let's go." The lieutenant immediately shook his head with a smile, and then saluted Dorjee and the others before speaking.

"Yes!" Dorjee and the others naturally had no opinion, and when the captain led a group of soldiers and led them to the middle of the two columns of soldiers, a captain standing on the ground shouted loudly: "Lizheng! ”

"Huh!" With a uniform voice, all the soldiers withdrew their feet from the outstep, their legs together, and their heads held high.

Dorjee and the others were stunned for a moment, but before they could react, they heard the captain on the ground shouting: "Salute to the hero!" ”

With a sound of "smack", the sound of drawing knives in unison, the Tang knives on the waists of all the soldiers were drawn, and then almost at the same angle "click" and "click" twice, the tip of the knife pointed upward, standing in front of them.

Rulin's blade shone in the sunlight, but at this moment, Dorjee and all the Tibetan herdsmen who were watching were stunned, this is ...... Paying a salute to them?!

These soldiers of the Tang Dynasty are saluting these people?! Say they're heroes?

Dorjee felt that something was surging in their chests, and their eyes were a little hot, but everyone tried their best to hold back, they wanted to return the salute, but they didn't know why they couldn't move, so they could only let the horses lead a small group of soldiers in front of them to walk forward.

At this moment, Dorjee and the others had an unprecedented glory in their hearts, they called him a hero, but Dorjee knew that now ...... He's not a hero yet! Maybe one day he can lead more Tibetan slaves to get rid of those slave owners, and he can be called a hero!

Dorjee buried this thought deep in his heart and didn't say it, but his eyes became extremely determined.

It wasn't until the last of them left the ranks of soldiers that Dorjee faintly heard the roar of "Libi" coming from behind him.

Dorjee didn't look back, the sound of horses' hooves under their feet called horseshoes became crisp and urgent, and they ran towards the future towards the rising sun.

After Dorjee and the others left, the soldier captain who stayed in place said in the same voice: "Line up!" ”

"Ka" and "Ka" started from a distance, and the soldiers quickly ran closer, and soon several neat lines appeared in front of the families of Dorjee and the other seven people.

"Salute!" With the order of the captain, the same etiquette appeared again, only this time not to these people of Dorjee, but to these families of theirs.

The family members of Duoji and the other seven people were a little at a loss, not knowing what to do, Lin Quan, who was standing next to them, said softly: "It's okay, you are all worth it, they are soldiers of the Tang Dynasty, and they are also responsible for protecting you Tang people, soldiers of the Tang people, you can turn to them for anything in the future." ”

The people of the Tang Dynasty? All the onlookers, the former Tubo slaves were in a trance, it turned out that they were already the people of the Tang Dynasty? Is this the difference between Datang and Tubo?

……

"Lu Hai, I'll leave it to you here, this area is kept secret for the time being, I have already explained General Li and Su Dingfang to cooperate with you, externally this is here to study brand-new craftsman tools, but internally you know what to study, in addition to the results of weapons, I hope you can let these craftsmen sort out the ideas of those machine tools I took out, and it is best to form an assembly line of machine tool operations." Li Ke was explaining things to Lu Hai, because he was about to leave for Chang'an.

It is already the beginning of October, and when he returns to Chang'an, it will already be November, and Chang'an has already entered winter, and it is estimated that it will already snow by then.

"Yes!" Lu Hai took a deep breath and said, When His Highness left this time, he provided a set of books for the craftsmen here, which was a set of books on building machine tools.

These machines are made of different steels, pig iron, etc., and they can speed up the production, grinding and other work of a certain part to the same standard through the ingenious combination of components.

In addition, His Royal Highness provided some suggestions for weapons here, such as adding two bow arms to the current military bed crossbow in the Tang Dynasty to become a three-bow bed crossbow.

That's right, some jobs are inconvenient to do in Chang'an, but it's no problem in Xizhou, and at present, if Li Ke wants to keep it secret, it's not too simple.

In this R&D area set up this time, Li Ke concentrated a large number of craftsmen, and he took out the concept book of manual machine tools.

Machine tools are the starting foundation of modern industry, and later generations have been machine tools are also national pains, but they have been overcome later. In fact, machine tools are not a new thing, the original machine tools, as early as the Han Dynasty people played.

Of course, it wasn't a machine tool at that time, but it was already a machine tool concept.

And Li Ke took out this book is the modern machine tool concept compiled by later generations, as well as a system of basic manual machine tools, as long as the system is thoroughly understood, these machine tools can gradually develop to higher precision.

At present, there are two sets of machine tools in the industrial area, which are mainly used to process wood and make arrow shafts.

After arranging these itineraries, Li Ke's itinerary was also set, and he set off in three days and returned to Chang'an!
