A scholar of Zhenguan in the Tang Dynasty

Lu Dongzan nodded to Songtsen Gampo with the most noble Tubo etiquette.

That night a group of fast horses entered the Hexi Corridor, and someone came to Yuchi Jingde's tent, "Your Majesty has an order! No matter what the reasons are, Tubo is not allowed to cross the Hexi Corridor!"

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

The soldier who rushed over said, "This is the plan of General Li Jing and His Majesty. There are already ministers from the court who have left the pass, and the general is invited to sit in the Hexi Corridor."

"Okay!" Yuchi Jingde responded with great enthusiasm.

The biting cold wind of winter blew across Chang'an, Fang Yizhi was carefully packing up the ancient books, and asked his father beside him, "My child has always wondered why the court sent envoys to various countries."

"Your Majesty met Li Jing a few days ago." Fang Xuanling said, "This is the result of the discussion between Your Majesty and Li Jing. Now that the Turkic army has been defeated like a mountain, it is the time when the Great Tang is gaining power. On the one hand, His Majesty wants to beat him The Turks used to frighten the countries, but on the one hand they also wanted to appease the countries, just like teaching an animal, if you slap it and then give it a sweet date, it will be more honest.”

"My son understands." Fang Yizhi put the ancient books away in order, "Actually, Songtsan Gampo is the one that my son can't put down the most."

"Indeed, you are right." Fang Xuanling also said, "The only thing His Majesty did not send the ministers of the court to Tibet is the matter of sending envoys to other countries. Do you know why?"

Fang Yi sat up straight 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 today's Datang, but if a wolf appears in the pack The situation is different for a maverick alien, in order to be united, the wolves will definitely get rid of this alien first, and then deal with the tiger."

The study room at home was very quiet, Fang Xuanling dropped a piece on the chessboard and continued, "Everyone is afraid that someone will bite themselves in the back during the melee."

Fang Yizhi played chess with his father and also had a son, "Father means that the strategy of His Majesty and General Li Jing is to isolate Tubo and create a different kind of Tubo."

"Never underestimate the smart people in the world." Fang Xuanling continued: "If the old man is right, now Tubo is also sending envoys to the various countries to join forces. Central Plains has long been tired of playing this game. Tubo There's more to learn."

Fang Yi looked straight at the dark cloud-covered sky and sighed repeatedly.

A month later, Yanmenguan was snowing heavily again, and it was freezing cold. A strange thing happened here. Gu Qing was inoculating the soldiers with cowpox, and there were grassland cows infected with smallpox in the army.

Cheng Chumo clutched his arm, "Gu Qing, do you think we won't be infected with smallpox now?"

The earliest cowpox appeared in the [-]th century, and the principle is actually very simple. The antigenic body of the vaccinia virus is similar to that of the smallpox virus, but people will only feel a little uncomfortable after being infected with the vaccinia virus. A kind of immune body, similar to the immune body of chickenpox, people will have immune body after getting cured of chickenpox.

The same is true for cowpox. Medical scientists have discovered that the antigenic body of the smallpox virus is similar to that of cowpox. Just like water can put out a fire, so can sand. There is a scar on it, which is formed by planting vaccinia, and it is also the earliest way to popularize vaccinia.

Su Dingfang was also covering the bleeding wound on his arm, unable to understand this method, Cheng Yaojin was also puzzled, "Gu boy, don't lie to me, such a severe plague can be cured with a few cows!"

In the days that followed, Gu Qing continued to conduct experiments. Many soldiers had a fever after being planted with cowpox. Cheng Yaojin held up the three-axe, "Old cow, don't stop me, I'm going to kill this kid!"

"Calm down!" Niu Jinda persuaded.

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

"Report!" A soldier came back and said, "General, all the sick barracks have been cured!"

"Healed?" The murderous aura on Cheng Yaojin's body suddenly disappeared.

"Yes!" said the soldier, "everyone is alive and kicking."

"What a baby, what a baby!" Cheng Yaojin patted Gu Qing's shoulder, "If you have time, spend time with that kid from my house, Chumo, he is so sweet! I'm half as smart as you, so I can be more relieved, huh? Where did the ax come from, old cow, don't stuff the ax into the old man's hand for no reason, and scare Gu Xiaowazi!"

Niu Jinda found a few Turkic people on the grassland, planted cowpox on these Turkic people, and threw them into the corpses of Turkic people with smallpox virus for more than ten days. Sure enough, these Turkic people 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, I will thank you for the people." Niu Jinda said.

"Actually, this can only be prevented. If someone has already been infected with smallpox, it won't work." Gu Qing said.

Chapter 144 Counterattack

After making all the preparations, the Yanmenguan army marched in front of the grassland, and the army stepped on the grassland mightily.

Gu Qing, Su Dingfang, and Cheng Chumo led an army of [-] soldiers and marched in the snow.

On the other side, Cheng Yaojin and Niu Jinda retreated with an army of 15. The sound of horseshoes on the grassland continued, and the Datang army began to counterattack like a net, killing all the way to the depths of the grassland.

Cheng Chumo, Gu Qing, and Su Dingfang also divided into three armies with [-] troops each.

There was blood everywhere on the grassland, and Cheng Chumo killed a tribe covered in blood everywhere, "I want you to return ten times and a hundred times the blood that our Tang soldiers shed!"

The explosives exploded in the Turkic camp, and the generals of the Tang Dynasty have long since killed their eyes, killing each and every one of them.

At this moment, the country's enemies and the family's hatred retaliated wildly.

Su Dingfang led an army of [-] to surround a tribe of Turkic troops. Compared with Cheng Chumo's rampage, this place is more refined and killed at every step.

Gu Qing also led an army of [-], and was chasing and killing these Turkic people. One side was chasing and the other was running away on the grassland. Yang Sheng led hundreds of people to stop these people, and said to the hundreds of soldiers around him, "This time We don't need firearms, just go straight in!"

"Yes!" replied the soldiers.

Gu Qing didn't do anything here, but watched Yang Sheng lead people to fight the Turkic people. This is the best opportunity to train a killer.

"Kill them all, you want to wipe out the grasslands! You will be punished by Changshengtian!" An old Turkic man wailed.

"Coincidentally, I never believe in God, let alone your Longevity." Gu Qing sneered.

Yang Sheng waved the blood on the knife, and walked step by step in front of the terrified Turkic people. The knife waved in the cold wind, and the blood drifted, "You rush into Yanmen Pass and kill my Tang soldiers! If you don't kill thousands of miles of people, we will Go home with no face!"

There was blood on the armor, and all the Turks fell down, only the soldiers of the Tang Dynasty stood.

For several days, Gu Qing held more than a dozen Turkic camps. After the blood on Yang Sheng's armor dried up, there was fresh blood again. The people under Yang Sheng's hands were like killing gods.

In front of Gu Qing's eyes are fighting, blood flow and flames, and when he looks up, there are only a few lonely stars on the other side of the sky. If there is a God, he really wants to kill and ask God.

When it is rectified again, no one in the army is willing to get close to Yang Sheng's group. This kind of murderous look is very scary.

"Tired?" Gu Qing handed Yang Sheng a water bag.

"Tired!" Yang Sheng said.

"Okay." Gu Qing patted his shoulder and got up.

A few days later, the [-] troops reunited again.

Gu Qing asked Su Dingfang, "How many tribes did you destroy?"

"Not many! Ten or so." Su Dingfang said.

"I'm freezing to death." Cheng Chumo sniffed his nose.

Su Dingfang rode his horse and walked aside, "It's like this on the grassland, it's very cold."

The scouts sent out came to report, "Report to the three major generals! Many Turkic corpses were found ahead."

"Corpse?" Gu Qing pulled the reins to stop the army from advancing, "How many are there?"

"Not many! A total of thirty or so!" The scout replied, "According to General Zhong Lang's order, we did not touch the corpses."
