"Liulang, you are late this time. I was appointed by Your Majesty as the supervisor of the Chang'an Observatory as soon as I came back. I really can't take time now!" Yuwen Hu said with a wry smile. With his relationship with Li Yan, he would naturally not refuse to help him, but Li Shimin stayed behind in his personal life, so he didn't dare to delay.

"Observatory?" Li Yan was stunned after hearing this, and then asked, "But is the observatory about the meridian that is to be built outside the south gate of Chang'an?"

"That's right, I heard that it was requested by Lord Li Chunfeng and Li of the Grand Historian. Moreover, the construction requirements of this observatory are extremely high. Not to mention its height and strength, it must also be built on the central axis between Chang'an Street and the Imperial City, and a section of railway tracks must be laid on this line. In the future, this line will be the prime meridian of the entire world, that is, the zero-degree meridian!"

When he got here, Yuwen Hu suddenly slapped his head and smiled ashamedly: "Haha~, look at my head, the concept of longitude and longitude was proposed by Liu Lang. I actually forgot it. It's really a show of my skills!"

The Yuwen family was originally a building family. Although Yuwen Hu has switched to gunpowder, he is still the leading architect of the Tang Dynasty. So if there is any important project, Li Shimin was still the first to think of him. What made Li Yan laugh and cry was that Yuwen Hu obviously did not understand the importance of the military academy. Of course, the observatory is also very important, but in comparison, the observatory can be built at any time, and the earlier the military academy, the better.

"Brother Yuwen, about the observatory, I'll help you and your father, and postpone it for the time being. If it really can't be postponed, let others do it. After all, you are not the only one who works on construction in the Tang Dynasty, and the affairs of the military academy are really too important. I'm not at ease to leave it to others. I'm afraid that the entire Tang Dynasty can take on this burden, Brother Yuwen!" Li Yan emphasized the importance of the military academy and praised Yuwen Hu.

Since Li Yan said so, Yuwen Hu stopped refusing and nodded in agreement. At the same time, he was a little curious about the military academy mentioned by Li Yan, and pulled Li Yan to ask for details. He was at least in charge of gunpowder production and was considered half a soldier. Therefore, after listening to Li Yan's introduction, he could understand the significance of the military academy. In addition to being shocked, he also strengthened his confidence in building a military academy forever, because this may be the most proud work in architecture in his life.

After saying goodbye to Yuwen Hu, Li Yan immediately asked Li Shimin for someone, but the other party agreed very simply. He immediately handed over the construction of the observatory to others, and Yuwen Hu fully assisted Li Yan in building the military academy.

With a professional assistant like Yuwen Hu as an assistant, Li Yan immediately became relaxed. He didn't have to worry about selecting craftsmen and preparing various building materials. Everything was left to Yuwen Hu and his helper. Soon the preparation was almost done. The next step was to ask Li Yan for the site selection.

Military academies are not like ordinary academies or private schools. Just find a place in the city. Students in military academies not only need to undergo book education. They also need to receive various trainings in normal times. Therefore, military academies have high requirements for terrain. At least mountains, rivers, etc. must not be missing, so they can only be built outside the city.

At first, Li Yan proposed to build it in the east of the city because his Qi Prince's Mansion was on the east side of the imperial city. After leaving Tonghua Gate, he would go to the eastern suburbs. If the military academy was built there, it would be convenient for him to check the progress every day.

However, his suggestion was opposed by Yuwen Hu and his craftsmen. According to their statement, the military academy is the cradle of future lieutenant generals and is responsible for killing and killing. The east belongs to wood and is the direction of the main birth, which is exactly the opposite of the function of the military academy. Therefore, the military academy must not be built in the east, but should be built in the west of Chang'an City, because the west belongs to metal and belongs to the white tiger among the four phases. The white tiger is also a ferocious beast that kills and kills. Since ancient times, it has represented majesty and the army, so the construction of the military academy is very consistent with the West.

As a modern person, Li Yan naturally despised this feudal superstitious statement, but the truth was to follow the local customs. He also knew that due to the influence of the Jin Dynasty, the Feng Shui theory was very popular during the Sui and Tang Dynasties, especially in terms of architecture, whether it is houses or cemeteries, they were almost influenced by Feng Shui theory. Therefore, it is not surprising that Yuwen Hu and others had such an idea.

It was just west, just a few more steps. Then he personally took Yuwen Hu and other craftsmen to almost run around the western suburbs of Chang'an. He finally chose a few suitable places. After on-site investigation by Li Xiaogong and Li Jing, he then selected three to report to Li Shimin. Finally, he finally set the address of the military academy in the downstream of the Jingshui River in the western suburbs, not far from the west after coming out of the Golden Light Gate.

The reason why it is set there is a complex terrain, mountains, rivers, and even a large green swamp. In addition, there is a huge flat land in front of the mountain, just for building a military academy. In addition, it is also close to Chang'an. If there is any change in Chang'an, you can quickly mobilize these loyal students to the city to maintain order.

After the school site was selected, Yuwen Hu began to become busy because he wanted to design the layout of the military academy as soon as possible according to the terrain. Although Li Yan was an amateur, he was also involved in it, mainly to remove some flashy things from Yuwen Hu's design. In addition, the various buildings in the military academy do not seek beauty, and everything is sturdy and practical as its main purpose.

As a result, this design style made Yuwen Hu very uncomfortable. Sometimes when he saw what he had spent a lot of effort to design, Li Yan changed it to an ugly monster. Not to mention the anger in his heart. The two of them had almost three days, one small, one small, one small, one small, and one big, and sometimes even had to do something. However, after the fight, Yuwen Hu had to change how to change, because Li Yan was the general manager of the construction of the military academy. In addition, this also brought an unexpected benefit, that is, after the design drawings were finalized, the military power value of Li Yan and Yuwen Hu increased by a lot.

On the day of the start of the earthwork, Li Yan specially invited Li Shimin. Accompanied by Li Xiaogong and Li Jing, under the gaze of civil and military officials, Li Shimin personally laid the first shovel of soil on the foundation of the military academy. Then he stood on the temporary high platform and delivered an inspiring speech to the civil and military officials. Finally, he handed over a four-character plaque from the Tang Dynasty Military Academy to Li Yan, so that he could complete the construction as soon as possible, and that the recruiting military academy students could attend classes as soon as possible.

After the military academy started, Li Xiao suddenly became idle. He didn't have to worry about anything except to check the progress of the project occasionally. It was enough to have Yuwen Hu guarding there every day. However, he couldn't have idle for a few days, and he was soon taken to help by Li Xiaogong because he encountered a problem when he persuaded the retired veterans to come out of the mountain, and this problem was related to Li Xiao.

The Tang Dynasty came out in troubled times, and after its founding, it never stopped fighting. Wars of all sizes occurred almost every year. It was in this environment that created a group of powerful generals in the Tang Dynasty. Now if someone asked who was the most powerful general in the Tang Dynasty in the restaurant? Then the answers must be diverse. Some people may say it was Niu Jinda; some may say it was Hou Junji; some may even say it was on the battlefield of Goguryeo, leading more than a thousand royal palaces to capture Quan Gai Suwen, thus gaining fame...

However, if you put this question twenty years ago, the answers you get will probably be very unified. If you ask ten people, you will probably tell you at least eight of them. Apart from Qin Qiong and Qin Shubao, there is no other person to imagine! Even if you mention this name now, most people will still praise you. However, as time goes by, only some older people will remember the Qin Shubao, who was the bravest of the three armies.

From Qin Qiong, Li Yan was naturally very familiar with the main characters in the Romance of the Sui and Tang Dynasties. However, when he came to the Tang Dynasty, he realized that the novel was a novel after all. Qin Shubao in the Romance of the Sui and Tang Dynasties was only ranked thirteenth in the martial arts, and he could not tell how brave he was. However, from his usual chats with Qin Huaiyu, Cheng Huailiang and others, he slowly learned about a real Qin Qiong.

The Qin family was not born in a high school, and their ancestors were all civil officials. They were not considered a big family. The population was also very thin. However, the so-called heroes did not come from their origins. In the chaotic times between the Sui and Tang Dynasties, Qin Qiong relied on his own courage to fight a path of his own. When he followed Li Shimin to fight the world, whenever he encountered the challenge of the enemy generals, Li Shimin was definitely the first to send Qin Qiong to the formation, and Qin Qiong never disappointed him. Taking the other party's head among the troops was like taking objects.

Later, Qin Qiong and Yuchi Gong jointly led the Xuanjia Army. At that time, there were many forces in the Central Plains and countless powerful troops from all sides. However, in front of the Xuanjia Army led by the two, they were crushed into pieces. The most famous time was that the two followed Li Shimin and led the 3,500 Xuanjia Army to defeat Dou Jiande's army in one fell swoop. Such a brilliant victory was very rare in the entire history. At that time, it was also the time when the Xuanjia Army was the most powerful. It can be said that it was Qin Qiong and Yuchi Gong that established the title of the Xuanjia Army as the most powerful army in the world.

However, after Li Shimin ascended the throne, Qin Qiong was injured too much when she was young, and her health was getting worse day by day. She had no choice but to retreat from the army. She had been at home for nearly ten years.

When Li Xiaogong wanted to invite someone to teach in the military academy, the first thing he thought of was Qin Qiong. Although Qin Qiong was most famous for his own bravery, his bravery not only refers to his personal bravery. Back then, he was able to bring out the Xuanjia Army, the most powerful army in the world. With his ability to manage and train military forces alone, there was no general in the Tang Dynasty who could compare with him.

However, when Li Xiaogong found Qin Qiong, although the other party praised the military academy, he also said that he was in poor health and did not want to teach in the military academy. Li Xiaogong naturally refused to accept this, and pulled down his old face and rubbed it a few times. Finally, Qin Qiong let it go, but the other party made a very strange request!
