My Backyard is the Tang Dynasty

Cui Yingying was playing with the colored glaze beads, when she saw Li Yin came back, she took the colored glaze beads and walked up to Li Yin, saying: "His Royal Highness, look at this colored glaze beads, it was given to Binglan by Qin Huaiyu, have you ever seen me before?" Such a beautiful glass bead."

   Zheng Binglan blushed even more when she heard Cui Yingying mention this matter.

Li Yin looked at the glazed bead with some embarrassment. No matter how stupid Qin Huaiyu was, he would never say that the glazed bead was given to him by Li Yin, so Cui Yingying didn't know that it belonged to Li Yin, but she was very envious. This thing is very precious in the Tang Dynasty. It is usually a gift from the royal family, and some are shipped from Persia, and the value is also very high. Therefore, famous families will buy some colored glaze in order to show their status or compare with each other. The utensils are placed at home, and there are many impurities in the colored glaze at this time, which is not as crystal clear as modern colored glaze products.

The Zheng sisters and Cui Yingying are both from famous noble families, so they have seen these things before, so they also know the value of this glazed bead. Because of this, the three of them were so surprised when Qin Huaiyu gave this glazed bead to Zheng Binglan .

   "It's really beautiful!" Li Yin echoed, he couldn't tell in person that this was given to Qin Huaiyu by him. In modern times, this thing is still worth ten yuan, which is not as high as the value of a potato.

Li Yin came back, and the Zheng sisters should not stay here any longer in order to avoid suspicion, so they made up their minds to leave the South Courtyard. Seeing that the Zheng sisters were leaving, Cui Yingying exchanged the glass beads for Zheng Binglan, her eyes still fixed on the glass beads, Very envious, "The price of this glazed bead is not cheap, how could Qin Huaiyu have spare money to buy this?"

After the two left, Cui Yingying expressed her doubts. She was very clear about Qin Huaiyu's salary. It was only a hundred guan a month. Now, at most, she had saved about a thousand guan. About 10,000 yuan.

  Li Yan shook his head helplessly. Putting the cloth bag in Cui Yingying's hand, "Look for yourself!"

  Cui Yingying held the cloth bag, but felt that the bag was heavy, and there was a crisp "da da" sound inside when it was shaken. He followed Li Yin back to the room, put the bag on the table, and opened the cloth bag layer by layer.

   "Oh my god!" Cui Yingying opened her mouth in surprise when she saw what was inside, and then she realized, "Your Highness, you spend so much money selling jewelry. What a waste!"

Li Yin sat down, poured himself a glass of water, and said: "These things are valuable in Datang, but they are not valuable in Luo Anguo. The things you see are not even worth the usual money." Li Yin did not intend to tell Cui Yingying, these are all fakes, since they are beautiful lies, why bother to expose them, otherwise it would be too boring.

  Hearing this, Cui Yingying was stunned immediately, "These gems are only worth the usual money?". She held a ruby ​​and looked at it carefully in front of her, unbelievable.

   "That's right, Qin Huaiyu's glazed bead is the same, it's just an ordinary toy in Luo Anguo." Li Yin took a sip of tea and continued.

   After confirming that this is true. Cui Yingying's expression began to change, and suddenly she hugged all the gems in her arms, and said with a smile: "These are all mine, all mine. No one can **** them from me."

   Li Yan was speechless for a moment. It seems that no matter which dynasty women are in, there is a natural preference for gems...

  The next day, Wang Gui escorted the armor given to Li Shimin by Murong's father and Li Yin back to Chang'an on the agreed day. Before leaving, he specially came to Li Yin's mansion to say goodbye to Li Yin, and Li Yin finally completed the task assigned by Li Shimin.

After Wang Gui left, Yizhou started a new round of commercial promotion. Now Tong Nian has gradually become familiar with the procedures of promoting new products, advertising, on-site trials, white sugar and cooking oil are two things that Li Min does not need to explain. It has been published in the Tang Business Daily, and the training of chefs is also in progress, but now the Shengtang Chamber of Commerce itself is a brand, and the release of new products will immediately attract a large number of businessmen. After the approval was issued, merchants flooded into the Shengtang Chamber of Commerce to inquire about the information of these two products. Tong Nian did not immediately pay attention to these merchants, but pretended to be mysterious, waiting to create a greater publicity effect.

  Tong Nian is busy here in Shengtang Chamber of Commerce, and Li Yin does not want to interfere in the product promotion. Tong Yu brought good news to Li Yin at this time. Now the cannon has been officially tested successfully, and he just waits for Li Yin to go to check it.

  This morning, Li Yin was in a good mood when he got the news. He notified Qin Huaiyu and Zhu Youzhi, and the three went to watch the first batch of artillery together.

Tong Yu is leading more than a dozen craftsmen to set up targets in the valley two miles outside the Taoyuan Valley. The area of ​​Taoyuan is too small, and there are military camps and workshops inside. The range of the artillery is too far and the power is too great, so it is not suitable to be in Taoyuan. Conducting artillery tests, so during the development of the artillery, Tong Yu has been leading people to test the power and range of the artillery at the newly opened test field outside the valley. He just told Li Yin the news of the successful development of the artillery, because he wanted to show Li Yin the best.

On both sides of the small depression are bare high mountains, with only sparse trees on the mountain, and the scenery on the mountain is panoramic. There is a five-mile-wide, ring-shaped land between the high mountains, which is a very suitable place for artillery testing. When I came to Here, Tong Yu decided to stay here.

Li Yin took Qin Huaiyu and Zhu Youzhi to the artillery testing ground. It was the first time for Zhu Youzhi to come here. He did not expect Li Yin to have such a secret base, but he was also quite relieved, at least it showed that he had integrated Li Yin's circle.

   "Your Highness!" Seeing Li Yin coming, Tong Yu greeted Li Yin and greeted Qin Huaiyu and Zhu Youzhi.

  Li Yin was focused on the cannon, so he said, "Take me to see it!"

   "Your Highness, this way please!" Tong Yu stretched out his hand to lead the way, and led the three of them around a corner. The three of them saw three dark long tube-shaped objects located between the flat ground, which were undoubtedly artillery.

  Compared to Li Yin, Qin Huaiyu and Zhu Youzhi were more interested in these cannons, and they took a few steps forward to look around the cannons.

Speaking of artillery, Tong Yu actually developed it very early, but he was not satisfied with the front-mounted artillery of the 10th century, because he saw more excellent artillery from the technical information provided by Li Yin, so he continued to use it again and again. Improvement, until now because of the limitations of other auxiliary technologies in Taoyuan, he stopped developing it, and these artillery pieces are more in line with his requirements.

The three cannons that Tong Nian put on the test site have different shapes. The barrel on the left is very long, with a length of three meters and a diameter of 130mm. The wall of the cannon in red is at least half thinner, which greatly reduces the weight of the cannon. This is all because of Taoyuan's steel smelting technology, the introduction of Li Yin's technology, and the addition of video teaching, which has brought the steel smelting technology to a new level. building.

   "Why is the barrel of this artillery so long?" Qin Huaiyu asked after looking at it for a while.

  Tong Nian explained at this time: "This artillery with a long barrel is called a naval gun. As the name suggests, it is loaded on a warship. Because of the long barrel, this artillery has the longest range."

  Qin Huaiyu thought of the big ship under construction, and nodded thoughtfully.

  Zhu Youzhi occasionally saw the style of artillery in some modern books. He pointed to the smallest artillery on the right and said, "If I guess correctly, this is a field artillery?"

   "Yes, this is indeed a field artillery." Tong Yu was a little surprised, but Zhu Youzhi recognized it at a glance. He didn't know that the Military Academy also opened video teaching.

The cannon that Zhu Youzhi pointed to was placed on a two-wheeled vehicle. The cannon was fixed on a bracket on the vehicle, and a pull rod protruded from the back for traction. The length of the cannon was half that of the naval cannon, only about 1.5 meters. The caliber is 105 mm.

  There was only one cannon left, and Tong Yu explained together: "This is a siege cannon, which can also be used to defend the city. It has a relatively large caliber and loads a lot of ammunition, so it is very powerful."

  While several people were talking, the craftsman who set the target returned. They had already set the target on the mountain and were just waiting for the test.

   "Your Highness, are you going to try shooting now?" Tong Yu asked.

  Li Yin is very interested in the artillery developed by Tong Yu. He observed carefully just now, and these artillery are actually breech-mounted artillery. "Let's start!"

   Li Yin and the two stood on one side, waiting for the artillery firing test. Tong Yu was ordered to let the craftsmen start to adjust the angle of the artillery.

The craftsman manipulated the naval gun skillfully according to the order, apparently for frequent practice. After a while, two men adjusted the angle of the cannon, and the third opened the wooden box next to it, and took out a cylindrical shell from it. The craftsman opened the base of the cannon, and the craftsman holding the shells stuffed it in.

   "Your Highness, please cover your ears!" Tong Yu reminded.

   Li Yin covered his ears as he said, and Qin Huaiyu and Zhu Youzhi also covered their ears in a similar manner. Seeing that the three of them did as they said, Tong Yu shouted: "Let go!"

The craftsman listened to the order, grabbed a rope on the cannon, and yanked it violently. Li Yin only heard a "boom", and then the ground under his feet trembled. He looked at the distant mountain, one piled up The rocky mountain fell down in an instant, raising a cloud of dust.

  Li Yin was a little shocked, but what shocked him was not the power of the artillery, but the firing method of the artillery. He was already surprised by the rear-loading artillery, but he didn't expect it to be fired by percussion.

Qin Huaiyu and Zhu Youzhi's faces were pale, and those who let him fight over with thousands of horses and horses were also terrified by this scene, and the rocky mountain in the distance collapsed with a sound, and the distance was still It was very far away, with such a sharp weapon, wouldn't it be a snap to attack the city in the future? At this moment, they looked at Tong Yu with eyes full of awe. (To be continued..)
