Harold is 15 years old, the 19th son of the caliph, and his mother and Sheena's mother are both disgraced concubines, and they have a good relationship with each other, and Harold and Sheena have become friends.

After Sheena got married and went to the Tang Dynasty, Harold was very lonely and missed this sister very much. When I heard that she was back, I came all the way to greet her.

On the way to the palace to meet the caliphate, Harold asks about Sheena's marriage.

Sheena was in a good mood and enthusiastically told Harold about her happy life in Datang, as well as what she had seen and heard, which made Harold very envious.

He said: "Sister Sheena, you help me tell my father, and when you go back to Datang, take me with you." ”

Sheena said, "Okay, I'll do my best." ”

After the last send-off, the deputy prime minister of the Arab Empire, Williber, had already returned to Damascus and reported to the caliph about his trip to Chang'an, and the strength and wealth of the Tang Dynasty attracted the attention of the caliph.

Sheena returned to Damascus and was received by the caliph. At the time of the Greek reception, the Greek mother also participated.

In the past, Sheena was a dispensable daughter, but now her identity is different, she has become the imperial concubine of His Majesty the Tang Emperor, and the Tang Dynasty is such a powerful country that must be taken seriously, and the caliph's attitude towards her has changed. Correspondingly, Sheena's mother's status has also been improved.

Xue Rengui, Tang Fei, and director of the Foreign Trade Department of the Ministry of Foreign Trade also attended the meeting.

Flying Tiger Command.

Du He and Wei Chi Baoqi held a meeting of the squadron leader and above of the Flying Tiger Army.

Hundreds of officers entered the conference room, waiting for the bigwigs to appear. Soon, Duhe and the others came in.

The officers found that the bigwigs were all happy one by one, and they didn't know what good things they had encountered.

The chief of staff presided over the meeting, and he said: "Colleagues, there is good news to announce to you today. ”

The etiquette of applause was brought to the Tang Dynasty by Li Su and has been widely accepted by the people. With warm applause, Duhe stood up and said:

"Brothers, the emperor attaches great importance to our Flying Tiger Army, and he has decided to expand the Flying Tiger Army.

The new Flying Tiger Army was organized into a single headquarters, with direct teams and six brigades, each with 5,200 men. The total army is 40,000 people. ”

"Wow", another round of warm applause. With the applause, the officers all stood up and applauded even more enthusiastically.

The Flying Tiger Army has expanded its military strength, its strength has expanded, and its officers have had the opportunity to be promoted. It was originally the ideal of officers to be promoted and make a fortune, so it is no wonder that everyone is so excited.

After the last incident, Li Su deeply felt that although there are many troops in the Tang Dynasty, there must be a strong and absolutely loyal army by his side, which can play a key role in critical times.

All the backbones of the Flying Tiger Army are all their own cronies, or officers promoted by Du He and Wei Chi Baoqi from the Flying Tiger Army.

Within the Flying Tiger Army, it has formed its own unique culture, and the core idea of this culture is to be loyal to His Majesty the Emperor, and of course only loyal to Li Su alone.

Li Su's absolute concern for the Flying Tigers is the best in the whole army in terms of weaponry, salary, housing conditions, meritorious awards, and other aspects.

The other units of the Tang Army also had no objections. After all, the Flying Tiger Army's training is arduous and the tasks performed are cruel, which cannot be compared with other branches of the military.

Moreover, the most critical one, the Flying Tiger Army is the emperor's pro-army, and it is useless to envy.

In the direct team of the Flying Tigers, there is an imaginary enemy unit, which is disguised as various enemy units and used to train their own special forces units.

On this day, in the eastern suburbs of Chang'an City, two strangely dressed armies appeared.

One army was the hoplites of the Persian Empire, and the other was the armored cavalry of the Byzantine Empire!

These two armies each had about 1,000 people, and they each conducted combat drills on the playground with the Tang army.

It turned out that these two armies were imaginary enemy units used by the General Staff to train other units of the Don Army.

Li Su was a very hard emperor, and he often had to consult a large number of materials to select those that were helpful to the Tang Dynasty for reference.

It's hard work, and the information comes from the afterlife, and no one else can help him deal with it. Later, Li Su thought of a way, he negotiated the price of the information he consulted with the Taobao system, and after the Taobao system printed it, he shipped it to him.

All the materials that were transported, Li Su first reviewed, and deleted all the information that could expose the information of the later generations, such as time, or some character names, etc.

Among Li Su's wives, only Qibi Wuyun and Ashina Qing have not gone to work, and their main task is to be responsible for liaison with the Tiele Department and the Tuli Department, and there are not many things to do in normal times.

So, Li Su set up an office at home, and the materials from Taobao were first sorted out by them, and then distributed to various ministries of the imperial court as needed.

In the age of cold weapons, there were ten of the most powerful armies in the ancient world, namely the Macedonian phalanx troops, the Byzantine armored cavalry, the Roman legions, the Teutonic Knights, the Mongol iron cavalry, the Hun cavalry, the Han army, the crusaders, the Spartan heavy infantry and the Tang army.

Li Su sorted out the relevant materials separately, focusing on the analysis and study of the Byzantine armored cavalry of the capital and the heavy armored cavalry of the Persian Empire, the "Holy Fall Cavalry", which was famous for its dedication. And imitated these two armies, forming an imaginary enemy unit.

In the eastern suburbs of Chang'an City, there is a piece of land of 3,000 mu, which is the wasteland that Li Shimin rewarded him for planting high-yield wheat. Now give me the staff headquarters, to be used as a training ground for the imaginary enemy.

After the formation of the imaginary enemy forces, the armored cavalry of Byzantium and the heavy armored cavalry of the Persian Empire caused great confusion to the Tang army participating in the exercise, and at the beginning, they were repeatedly defeated.

As the exercise progressed further, the Tang Army participating in the exercise gradually figured out the operational characteristics of the imaginary enemy, and finally gave full play to the superiority of the Tang Army and defeated the imaginary enemy.

Li Jing and other high-ranking officials of the Tang Army were very appreciative of Li Su's training method of using an imaginary enemy.

Under the in-depth promotion of Li Jing and others, the imaginary enemy forces were no longer limited to the armies of the Byzantine and Persian empires, but expanded to the armies of all countries that could have a war with the Tang Dynasty.

In addition, this training method was extended to all military districts, and they set up imaginary enemy units according to the enemy they were facing. This training method has greatly improved the combat effectiveness of the Tang Army and has played a tremendous role in future wars.

At noon that day, it was almost time to get off work, and Concubine Yang sent someone to invite Li Su over.
