On this day, Pei Dilan, accompanied by Yin Guanghao, was entertaining in a green building, when he was suddenly called back by Baihu, saying that the prince had something very important to discuss with him.

Northwest Palace, Study.

"Lao Li, do you have something to do with me?" Pei Dilan asked. Pei Dilan knew the intimate name between Li You and Hamid, and he followed suit.

"Lao Pei, look at this." Li You said.

Pedilan took it and saw that it was a telegram from the Persian Coalition High Command.

At Li You's suggestion, in order to facilitate the coordinated actions of the three armies, the Tang Dynasty, Persia and the Great Food Kingdom established the Persian Coalition Army Command in Kabul, with Hamid as the commander and Cheng Yanjin and a general of the Great Food Kingdom as the deputy marshal.

After the formation of the coalition forces, the three armies launched an attack on the Persian rebels along the prescribed routes.

After the assassination of Hamid's father, the old Persian king Isiqi III, and the internal turmoil in the Persian region under his control, the new king was only 7 years old, and the cohesion was greatly reduced, and the coalition was moving relatively smoothly.

Not long ago, the Tang army joined the Great Food Army in Candela City. Before the siege of the city, the two sides drew a contract to make an agreement, and after the city was broken, the whole city was divided into two halves, the east side belonged to the Tang army, and the west side belonged to the Great Food Army, and the property in the governor's palace in the city was divided equally between the two sides, and a written agreement was signed.

After three days of onslaught, the coalition forces finally captured the city of Candela, and each occupied the pre-agreed city, and everyone was happy so far.

However, the Great Food ** team found that the western urban area occupied by them was relatively barren and not as rich as the eastern area occupied by the Tang Army, so it was unbalanced. The big food ** team has no fixed military salary, and all the income of the officers and soldiers comes from the capture, not only that, but 1/5 of the captured materials must be handed over. In this case, they can't help but be a little anxious.

According to the agreement between the two sides, no one was allowed to enter the Governor's Palace in advance, and both sides were to send someone together to count all the property in the Governor's Palace, and then the two sides divided it equally. As a result, the Great Food Army violated the agreement and sent a force at night to preemptively enter the Governor's Palace and loot.

The Tang army stopped doing it and sent troops to stop it, but the two sides fought, and each lost some men. The Tang army was well-equipped and well-trained, took advantage of a certain advantage in the battle, and in the end simply occupied the governor's palace. The two sides began to confront each other in the city, and a large-scale clash could break out at any time.

After the coalition high command got the news, it was also scratching its head about this matter. Hamid couldn't intervene in this matter, Cheng Yanjin and General Da Shi coordinated, but they didn't reach an agreement, they only temporarily stopped the two sides from further expanding the conflict.

Subsequently, they reported by radio what had happened in the city of Candela to Chang'an and Damascus.

Chang'an is naturally handled by Li You, and Damascus is not familiar with the situation in the Tang Dynasty, so he can only give this matter to Pei Dilan to deal with.

After Pei Dilan read the telegram, he felt that this was an opportunity to help Li You, and he immediately said that the fault of the matter first lay with the Great Food Army. On behalf of the side of the Great Food Army, he apologized to the Tang Army.

With Pei Lilan's attitude, this matter is much easier to handle.

After Li You and Pei Dilan discussed, Pei Dilan then made a report to Damascus.

Soon after, Damascus called back to agree to the solution discussed by Li You and Pei Lilan:

First, Li You first sent a telegram to the Tang army, telling them to withdraw from the governor's palace and not to cross the boundary of the city agreed with the two sides and clash with the other side.

Second, the generals who led the Great Food Army to enter the Governor's Mansion and some of the soldiers who killed and injured the Tang Army were beheaded in front of the Tang Army in the name of maintaining the military discipline of the Great Food Army.

Third, the property of the Governor's Palace was presided over by the Marshal's Mansion of the Allied Forces, and it was still divided equally according to the previous agreement.

Fourth, the Tang army looted the Dongcheng district they occupied for three days, and they were not allowed to set fire to it or destroy it except for the property they were willing to take away. Three days later, the Tang army withdrew from the city, leaving the big cannibals to loot and loot.

This fourth article doesn't sound like it's interesting, the Tang army has been robbing for three days, what else can be left for the big cannibals?

Not really. The Tang army was an outsider, and they would not want those bulky items, but would only rob some money that was easy to carry, so the wealth they could take away was only a very small part.

The Great Food Army is different, they are backed by the area controlled by their Great Food Country, and the large items in the city, they can all be transported away and sold for money. They were so poor and greedy that they would tear down everything they could take with them, even the beams of their houses, and sell them.

There is a special unit in the Great Food Army, which is engaged in the sale of materials. It can be said that in the area ceded by the Tang Army, they got much more benefits than the part of the money that the Tang Army could take away.

The Tang army had face, calmed the anger of the soldiers, and the cannibals were compensated with money. The armies of both sides expressed satisfaction with the outcome of such a disposition.

After receiving the telegram from the Allied Command, Pei Dilan said with emotion: "It's good that there is still a radio station!" Lao Li, now there is only one radio station of your Tang Army in Damascus, and the 12 radio stations you promised me should be given to me quickly. ”

Pei Dilan liked the radio more and more, and he thought that after getting these 12 radio stations, he would decide to disassemble one after he went back and organize domestic skilled craftsmen to find a way to copy it.

Since Li You dared to give them the radio, he was sure that they would not be able to imitate it. It's like giving the G20 blueprints to a small country in Africa, and they can only stare dryly.

Just like with the current level of science and technology in the Tang Dynasty, Li You could not build a bearing, and it was impossible to build a bicycle.

Subsequently, Li You reported to Li Shimin and Li Chengqian what happened to the incident, his opinions on how it happened, and the final result.

The industrial foundation of the Tang Dynasty was weak, which could not be changed in a short period of time, and under the vigorous promotion of Li You, the Tang Dynasty has also made great progress in recent years.

On this day, the institute sent two kinds of cutting tools, high-speed steel and diamond, and reported to him the experimental results of the newly developed lathe.

Lathes are one of the important symbols of industrialization to improve labor productivity. In ancient times, lathes were pulled by hand or foot, the workpiece was rotated by ropes, and the tool was held to cut. In 1797, the British mechanical inventor Maudsley created a modern lathe with a lead screw to drive a turret, and in 1800 he adopted an exchange gear that could change the feed rate and the pitch of the thread being machined. In 1817, another Englishman, Roberts, adopted a four-stage pulley and a back-wheel mechanism to change the spindle speed. In order to improve the degree of mechanization and automation, in 1845, Fitch in the United States invented the turret lathe.

According to the existing materials and power levels of the Tang Dynasty, Li You provided the institute with a lathe invented by the Englishman Roberts with a four-stage pulley and a back wheel mechanism to change the spindle speed. With such a lathe, more tools can be machined and further development of science and technology can be promoted.

Li You once developed the use of electricity, because many related problems could not be solved, so it could not be used on a large scale for the time being. A steam engine was developed, but there was little progress. With machine tools and the imminent possession of rubber, a lot of things are possible.

Li You took Pei Dilan to visit the new lathe, and seeing Pei Dilan's envious eyes were about to turn green, Li You was full of confidence in dealing with Songtsan Ganbu.

On this day, Songtsen Ganbu finally came to Chang'an.
