Luo Zhaoyun was in charge of Huangshui City, staring at Wuwei County and Jincheng County, and Qinghan County were eyeing him, and he could rush his troops eastward at any time.

However, he temporarily stopped the offensive pace, in order to stabilize his footsteps, continue to expand his troops, absorb the people of Xiping County, tame the surrendered troops, and integrate them together, and the number increased by 20,000 to 30,000, but the training was not enough and it was quite chaotic, which was incomparable to the 20,000 or 30,000 elite troops he brought.

We can only speed up the training temporarily, and in a quick way, we can first master military rules and regulations, as well as basic placeholding, running, flags, drums, etc., and then through practical training, we can be brave after a few tough battles.

At the same time, Guo Xiaoke led his troops to attack Dahua City and Hejin City in Jiaohe County, which was easily occupied because there were generals of the Sui Dynasty guarding it. When they heard Luo Cheng holding an imperial edict and came to pacify the northwest, they were famous for their troops. They opened the city to greet him, attached to Luo Cheng, and waited for a unified dispatch.

In this way, the four counties of Xihai County, Heyuan County, Xiping County and Jiaohe County are connected together and are laid into one area, with a total population of 400,000 to 500,000. The territory of the four counties is equivalent to the size of eight counties in the Central Plains, but the population is only half of the four counties.

After all, it is a borderland with high mountains and steep mountains and deserts, vast land and sparsely populated areas, backward education, and many bad habits that require education and trade, improve the knowledge level of the locals and their living conditions. If there is any change, they will support him and be grateful.

On the map, he drew the Silk Road of the Hexi Corridor, and was about to establish many post stations to connect and form a line to strengthen communication with each other's four counties and with the Western Regions.

The post station was born from ancient beacon communication and has been in the form of a prototype since the Warring States Period. Qin Shihuang established the "Ten Miles and One Pavilion", called the Post Pavilion, which was not large in scale and limited in functions. In the early Han Dynasty, the post Pavilion was changed to a post Pavilion, also called a post Pavilion, which stipulated that a post Pavilion was 30 miles away, and the speed was improved. In the Sui Dynasty, the pavilion was established to provide accommodation for commuters, but the military effect was not high.

During the Song Dynasty, post stations began to deliver military intelligence, including official and military. During the Yuan Dynasty, it was the peak of the booming development of post stations. Because the horse-backed nation was faster, the post stations were able to transmit intelligence more greatly improved their functions.

Luo Zhaoyun referred to the post station management methods of the Yuan, Ming and Qing dynasties to establish a systematic and strict post station transmission system and added many contents and regulations.

For example: the organization of the station, the encryption and transmission of information, the management of nearby pasture land, the supervision of envoys, the food supply of the station, the exchange of temporary supplies, etc.

Each post station has a post officer, a postman and a staff officer. There are two teams of soldiers who are about 100 people to defend, but most of them are old, weak, sick and disabled soldiers, alleviating the pressure on the army to dispatch.

"It won't take long to connect these four counties, and the intelligence and supervisors will be communicated to various places in a timely manner, strengthening the connection between local governments and general managers." Luo Zhaoyun was a little expectant. These settings seemed inconspicuous, but once they were operated, they would play a huge role.

Li Yuan summoned military officials and generals to discuss the matter of advancing and retreating. In the end, 70% of those who agreed to retreating were accepted. Even though Li Shimin, Liu Hongji and others tried to persuade him, Li Yuan's idea was not changed.

This time, Li Jiancheng did not stand on the same front with his second brother, but supported his father, Duke Tang, and temporarily returned to Jinyang to ensure that the base camp was not lost and resisted the attacks of Liu Wuzhou and the Turks. Secondly, it was also because the march route was blocked, and heavy rain fell for more than half a month, and the food and grass were deficient, so it would be too late if it didn't leave.

Li Shimin was unwilling to accept it. He was determined to do big things. The opportunity had come. He knew very well how good it would be for the Li family to occupy Daxingcheng. However, at this critical moment, few people agreed with his aggressiveness. On the contrary, 70% of people stood in the opinion of Li Yuan and Li Jiancheng, believing that the second young master was still young and not worthy of acceptance.

After the meeting, Li Shimin was so depressed, but he was not yet old and had too little experience in leading the army to fight. He usually didn't like to read books and read classics, etc. Some counselors and wise men thought that Li Er was smart, but not solid, easy to change, and too aggressive.

"These people are so short-sighted. Why can't they see the benefits of attacking Daxing City first in one go? It's a sudden change!"

Li Shimin returned to his tent and complained, and Liu Hongji, Tang Jian, Duan Zhixuan and others comforted the second son of the Li family.

"I didn't succeed in the army and suddenly withdrew from the army to the north, which had a great impact on morale. What did the Guanlong nobles and the Central Plains heroes view us?

"Your Highness is careful and be careful of the walls." A counselor reminded.

"At present, Mr. Tang has given his opinion, and no one can persuade him to go in."

Li Shimin looked anxious and sighed: "Does my Li family really have no luck?"

At this moment, a guard came in to report that a woman in white came to meet the second son of Li Shimin.

"Woman in white, who is this? Is it the successor of Butian Pavilion?" Li Er was a little confused.

"Come on!" Li Shimin continued to give the bill to greet him.

Soon, Ye Junyao wore a hat, tulle and white clothes, as outstanding as a fairy.

Li Shimin stood in the room and paced, waiting for the curtain to be opened and the successor of Butian Pavilion appeared before he recovered and greeted him enthusiastically.

"Miss Ye, we're meeting again." Li Er couldn't help but want to get closer to each other.

Ye Junyao said: "I appeared this time to solve the problem for the Tang army. I already know the debate at your meeting today. I plan to meet Mr. Tang and explain the interests. I must take down Xijing as soon as possible. In this way, the Li family will have the opportunity to unify the world and rebuild a new dynasty."
