Tubo, Songtsen Gampo has been paying close attention to the movements of Yanmen Pass these days. As long as the Turks broke through Yanmen Pass, the 300,000 troops that had been prepared for a long time rushed into the Hexi Corridor in one breath. However, the army arranged by the Tang army in the Hexi Corridor remained motionless. Is Yanmen Pass not broken yet? The Tang army was so calm and calm, and the worries in their hearts became deeper.

"Dear Zamp!" A Tubo man came, "This is the battle report of Yanmen Pass!"

Songtsen Gampo immediately took the battle report and started to read it. Seeing the above narrative, he felt a lot of cold. The Turks led hundreds of thousands of troops to knock on the gate and were beaten by the Tang army with only tens of thousands of people!

In just a few years, I conquered the entire Tubo, and in just a few years, the military strength of the Tang Dynasty was already deterred. Songtsen Gampo sighed, "I will write a letter to the king of the Tang Dynasty, and I am willing to cross the Hexi Corridor to fight against the Turks together."

Lu Dongzan, who was riding on one side, also said, "Li Shimin is an ambitious king and has to be careful."

Songtsen Gampo nodded, "The firearms of the Tang Dynasty made me uneasy, and in the words of the people of the Central Plains, they couldn't sleep or eat!"

Lu Dongzan rode a horse and pulled the reins and looked at the Hexi Corridor in the distance, "If the national strength of the Tang Dynasty recovered in a few years, it might be a disaster for our Tubo. We should either surrender or destroy it."

"This Tubo was defeated by my Songtsen Gampo!" Songtsen Gampo said, "But my dynasty will never become a vassal of the Tang Dynasty. Let the tiger of the Tang Dynasty fall asleep first. Lu Dongzan, you will also travel for me, and also travel for Tubo to join forces to attack the Tang Dynasty! Let the Tang Dynasty not recover its vitality, tell the king of the Tang Dynasty why there is no living gulf at Yanmen Pass! Massacre more than 100,000 Turks!"

Lu Dongzan nodded and gave Songzangan the most noble Tubo etiquette.

That night, a group of fast horses entered the Hexi Corridor and people arrived at Yuchi Jingde's tent. "Your Majesty has an order! No matter what the Tubo is for, Tubo must not be allowed to cross the Hexi Corridor half a step!"

"Is Your Majesty going to use troops against Tubo?" Yuchi Jingde was puzzled.

The soldiers who arrived said, "This is the strategy of General Li Jing and His Majesty. Some ministers in the court have already left outside the pass. They also ask the general to sit in the Hexi Corridor."

"Okay!" Yuchi Jingde responded with great enthusiasm.

The biting cold wind of winter blew over Chang'an. Fang Yizhizheng carefully packed up ancient books and asked his father beside him, "The child has never understood why the court has sent people to various countries."

"Your Majesty had seen Li Jing a few days ago." Fang Xuanling said, "This is the result of the argument between Your Majesty and Li Jing. Now the Turks are defeated like a mountain. It is the time when the Tang Dynasty established its authority. On the one hand, Your Majesty wants to attack the Turks to intimidate the countries, and on the other hand, he also needs to appease the countries. Just like teaching animals a lesson, slapping them and giving them a sweet date, it will be more honest."

"I understand." Fang Yizhi put the ancient books in order, "In fact, the person Songtsen Gampo is the person who can't let go of the most is the person who can't let go of it."

"Indeed, you are right." Fang Xuanling also said, "Your Majesty did not let the ministers in the court go to Tubo for the matter of sending missions to Tubo, do you know why?"

Fang Yi sat upright in front of his father.

Fang Xuanling continued, "When the wolves are targeted by a tiger, the wolves will remove the tiger in order to survive, and this tiger is the current Tang Dynasty. But if a maverick alien appears in the wolf pack, it will be different. In order to be able to work together, the wolves will definitely eliminate the alien first before dealing with the tiger."

The study room at home was very quiet. Fang Xuanling fell on the chessboard and continued, "Everyone is afraid that someone will bite him behind his back when he is fighting again."

Fang Yizhi played against his father and also lost a son. "What my father meant is that the strategy of His Majesty and General Li Jing was to isolate Tubo and create an alien."

"Never underestimate the smart people in the world." Fang Xuanling continued: "If I was right, Tubo is also sending envoys to various countries to join the Zongli and Lianheng. I have been tired of playing this kind of game in the Central Plains, and Tubo still learns it."

Fang Yi looked at the sky covered by dark clouds and sighed repeatedly.

A month later, it started to snow again in Yanmen Pass and the weather was cold and the ground was frozen. A strange thing happened here. Gu Qing was growing cows for the soldiers, and grassland cows dyed with smallpox were in the army.

Cheng Chumo covered his arm, "Gu Qing, do you think we won't get smallpox now?"

The earliest vowel appeared in the 18th century. In fact, the principle is very simple. The vowel virus has similar antigens to smallpox virus. However, people will only feel a little uncomfortable after being infected with vowel virus. After being infected with vowel, an immune body will be produced in the human body, similar to vowelpox. After being cured with vowelpox, people will have an immune body.

The same is true for vaccinia. Medical scientists have found that the antigen of smallpox virus is similar to vaccinia. Just as water can extinguish fires and sand can extinguish fires, vaccinia allows the immune bodies produced by the body to resist smallpox, which means that there is a scar on the arm of the older generation. This is the formation of vaccinia planting and it is also the earliest way to popularize vaccinia.

Su Dingfang also covered the bleeding wound on his arm, unable to understand this method, Cheng Yaojin was also confused, "Boy Gu, don't lie to me. Such a powerful plague can be solved by just a few cows!"

In the following days, Gu Qing kept doing experiments. Many soldiers had fever after planting cowpox. Cheng Yaojin carried three axes, "Old cow, don't stop me, I want to kill this kid!"

"Calm down!" Niu Jinda persuaded.

"Uncle Niu, it's just a fever, nothing big deal." Gu Qing explained as he looked at the big axe and said with black lines.

"Report!" a soldier returned and said, "General, the sick military camp has been cured!"

"Healing?" Cheng Yaojin's murderous aura suddenly dissipated.

"Yes!" said the soldier, "all of them are still alive."

"Good doll, good doll!" Cheng Yaojin patted Gu Qing on the shoulder, "I have time to mourn the boy with my family everywhere. He is so melon! Having you is half clever, I can comfort you, Huh? Where does the axe in my hand come from? Old Niu, don't put an axe into my hand for no reason, what should I do if I scare Gu Xiaowazi!"

Niu Jinda found several Turks on the grassland, and asked these Turks to plant cowpox, and then threw them into the bodies of Turks with smallpox virus for more than ten days. Sure enough, these Turks were still intact!

"Boy, your new firearm can kill people, and your cowpox can also cure people. If there is no smallpox plague in the Central Plains from now on, I would like to thank you for the people." Niu Jinda said.
