As soon as the Turks break through the Yanmen Pass, the 300,000 troops that have been prepared for a long time will enter the Hexi Corridor in one go, but the army of the Tang Army arranged in the Hexi Corridor will not move at all, and the Yanmen Pass has not been broken? Tang Jun was so calm and relaxed, and the worry in his heart deepened.

"Dear Zamp!" A Tibetan man walked over, "This is the battle report of Yanmen Pass!" ”

Songtsen Gampo immediately took the battle report and read it, looking at the above narrative, his heart was cold, the Turks knocked on the pass with hundreds of thousands of troops and were beaten by the Tang army with only tens of thousands of people!

In just a few years, he conquered the entire Tubo, and in just a few years, the military strength of the Tang Dynasty has long been prohibitive, Songtsen Gampo sighed, "I will write a letter to the monarch of the Tang Dynasty, and I am willing to cross the Hexi Corridor to jointly crusade against the Turks." ”

Lu Dongzan, who was riding on one side, also said, "Li Shimin is an ambitious king, so you have to be careful. ”

Songtsen Gampo nodded, "The firearms of the Tang Dynasty make me uneasy, in the words of the Central Plains, it is difficult to sleep and eat!" ”

Lu Dongzan rode the reins and looked at the Hexi Corridor in the distance, "If we wait for the recovery of the national strength of the Tang Dynasty in a few years, it may be the catastrophe of our Tubo, either surrender or destroy." ”

"This Tubo was single-handedly brought down by my Songtsen Gampo!" Songtsen Gampo said, "It's just that my dynasty will never become a vassal of the Tang Dynasty, let the tiger of the Tang Dynasty fall asleep first, and Lu Dongzan will take you for me and for Tubo to travel to the countries!" United crusade against the Tang Dynasty! , taking advantage of the fact that Datang has not yet recovered, inform Datang Guojun why Yanmen Pass does not leave a living mouth! Slaughter more than 100,000 Turks! ”

Lu Dongzan nodded and gave Songtsen Gan the highest Tibetan etiquette.

That night, a group of fast horses entered the Hexi Corridor, and the people who came arrived in Wei Chi Jingde's tent, "Your Majesty has an order!" No matter what the reason for Tubo, Tubo must not be allowed to cross the Hexi Corridor by half a step! ”

"Is Your Majesty going to use troops against Tibet?" Yu Chi Jingde was puzzled.

The little soldier who rushed to say said, "This is a strategy from General Li Jing and His Majesty, and the ministers of the DPRK and China have already left the Guanwai, and they also asked the general to sit in the Hexi Corridor." ”

"Good!" Wei Chi Jingde responded with a full of energy.

The bitter cold wind of winter blew over Chang'an, Fang Yizhi was carefully packing up the ancient books, and asked his father beside him, "The child has always wondered why the DPRK still sends people to envoy to the countries. ”

"Your Majesty had already met Li Jing a few days ago." Fang Xuanling said, "This is the result of the strategy between His Majesty and Li Jing, now that the Turkic army is defeated, it is the time for the Tang Dynasty to establish its might, on the one hand, His Majesty wants to attack the Turks to deter the countries, and on the other hand, he also wants to appease the countries, just like teaching animals, slap and give a sweet date, it will be more honest." ”

"Got it." Fang Yizhi put the ancient books in order, "In fact, the most unbearable thing for children is Songtsen Gampo." ”

"Indeed, you're right." Fang Xuanling also said, "Your Majesty is the only one who did not let the ministers of the DPRK and China send envoys to Tibet, 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 get rid of the tiger in order to survive, and this tiger is the current Datang, but if there is a maverick outlier among the wolves, the situation is different, and the wolves will definitely get rid of this outlier first before dealing with the tiger in order to be able to work together." ”

The study at home was very quiet, and Fang Xuanling dropped a son on the chessboard and continued, "Everyone is afraid that someone will bite them in the back when they fight again." ”

Fang Yizhi played against his father and also left a son, "What my father means is that the strategy of Your Majesty and General Li Jing is to isolate Tubo and create Tubo into an alien. ”

"Never underestimate the smart people in the world." Fang Xuanling continued: "If the old man is right, now Tubo is also sending envoys to various countries, and they are all over the place, and they are tired of playing this kind of game, and Tubo still has something to learn." ”

Fang Yi looked directly at the sky with dark clouds and sighed again and again.

A month later, it snowed heavily in Yanmen Pass, and the weather was freezing, and a strange thing happened here, Gu Qing was planting cowpox for the soldiers, and a grassland cow infected with smallpox was in the army.

Cheng Chu covered his arm silently, "Gu Qing, you said that we won't be infected with smallpox now." ”

The earliest cowpox appeared in the eighteenth century, in fact, the principle is very simple, the antigen of the vaccinia virus is similar to that of the smallpox virus, but people infected with the vaccinia virus will only be slightly uncomfortable, after being infected with cowpox, the human body will produce an immune body, similar to the immune body of chickenpox, and after the chickenpox is cured, the person will have an immune body.

The same is true for cowpox, medical scientists have found that the antigen body of the smallpox virus is similar to cowpox, just like water can extinguish fire, sand can also extinguish fire, cowpox allows the body to produce immunity to resist smallpox, that is, the older generation has a scar on the arm, which is formed by planting cowpox, and it is also the earliest way to popularize cowpox.

Su Dingfang also covered the bleeding wound on his arm, he couldn't understand this method, and Cheng Yanjin was also puzzled, "Gu boy, don't lie to the old man, such a powerful plague can be solved by a few cows!" ”

In the following days, Gu Qing kept experimenting again, and many of the soldiers had a fever after planting cowpox, Cheng Yanjin carried a three-plate axe, "Old Niu, don't stop me, I'm going to kill this kid!" ”

"Calm down!" Niu Jinda persuaded him.

"Uncle Niu, it's just a fever, nothing serious." Gu Qing looked at the big axe with black lines on his head and explained.

"Report!" One of the soldiers came back and said, "General, the sick barracks have been healed!" ”

"Healed?" The murderous aura on Cheng Biting Jin's body suddenly dissipated.

"Yes!" "All of them are still alive." ”

"Good doll, good doll!" Cheng Biting Jin patted Gu Qing's shoulder, "I have more time to talk to that kid at my house, he's too melony!" With you half smart, the old man can be relieved, huh? Where did the axe in the old man's hand come from, don't you stuff the axe into the old man's hand inexplicably, what should you do if you frighten Gu Xiaowazi! ”

Niu Jinda found a few Turks on the steppe, let these Turks also plant cowpox, and then threw them into the corpses of the Turks with smallpox virus and stayed for more than ten days, and sure enough, these Turks were still intact!

"Boy, your new firearm can kill people, your cowpox can also cure people, if there is no smallpox plague in the Central Plains from now on, the old man will thank you for the people." Niu Jinda said.

"Actually, this can only be prevented, if you have already been infected with smallpox, you will not use it." Gu Qing said.
