The pontoon bridge appeared as early as the time of King Wen of Zhou, and appeared several times in later wars, and by now, almost all generals know the role of pontoon bridges for the army.

However, due to the constraints of conditions, the pontoon bridge is not intended to be built.

The biggest problem in building pontoon bridges is that the ships must be unified, or as unified as possible, and those that are too different or too small will not work.

It is not impossible to build a boat on the spot like Li Yuanji, but the reason why there are not many pontoon bridges is because it is time-consuming and laborious, and it often takes several days to build a pontoon bridge and block the normal passage of the channel.

Therefore, there are not many pontoon bridges in the history of China.

Li Jing saw the pontoon bridge for the first time, and he felt very uncalm when he walked on it, and he always had the feeling that he would fall into the water, and he didn't even dare to ride a horse.

Walking across this pontoon bridge about a mile long in horror, Li Jing, who was the 'God of War of the Tang Dynasty', was also wet with sweat.

"Hey, it's a pity that this bridge is too inconvenient, time-consuming and labor-intensive, and obstructs the passage of the waterway, if such a bridge can be built in a short time, it will be more convenient for both the people and the army." Looking at the ups and downs behind him, and the frightened appearance of the soldiers, Li Jing had to admire Li Yuanji's idea.

The boat was not large, each craftsman was responsible for only one procedure, all the materials were standardized, and any one could be combined with another, and it only took one day to build more than fifty flat-bottomed boats.

"A ship is not heavy, and the carriage can be pulled away!" Li Yuanji smiled weirdly: "Do you want to buy some carriages?" ”

The corners of Li Jing's mouth twitched slightly, and he secretly said that Li Yuanji really didn't forget to do business wherever he went.

The carriages that wanted to pit the family ended up in their own hands, and now they want to sell these carriages to the imperial court?

However, the four-wheeled carriage seems to be really convenient, the speed is faster than that of ordinary carriages, the pack-horses are lighter, and the cargo capacity is also large, which is indeed very suitable for the army.

Thinking about it, Li Jing still shook his head: "This matter is not in my hands!" ”

……

The city of Fengzhou is very broken, it can be seen that the Turks are indeed not very suitable for living in the city, the good city has been made dirty and messy by them, and the traces left after the past battles are still lying there quietly, and even some blood stains can be faintly seen.

The city gate was wide open, but the city was empty, and last night, Tuli Khan evacuated Fengzhou with his subordinates, and took the initiative to let Fengzhou out.

"What are you doing with this?" Standing on the head of Fengzhou City, looking at the busy soldiers below, there was no shortage of war preparation materials such as rejecting horses, which were arranged by Li Jing in an orderly and orderly manner.

"Of course it's preparing for defense, are you waiting for the Turks to come?" Fengzhou City, in Li Jing's opinion, is just a big camp that doesn't need them to set up tents, and the defense that should be done is not less.

"It's better to sleep more with this kung fu, do the Turks have the ability to siege cities? Even if the war horse arrives at the city, he can't ride it, and besides, Fengzhou is just a temporary camp, and it won't be long before it will go north, and these walls are enough. Li Yuanji responded angrily, in his opinion, it was a complete waste of energy, it was better to let the soldiers sleep a little longer to recover from the fatigue of days of marching.

"There is no child's play...... You ......" I wanted to fight on the basis of reason, but I didn't expect Li Yuanji to turn around and leave, and the embarrassed Li Jing could only point to Li Yuanji's back and come back, I haven't finished talking yet.

"Your Highness, something has been discovered in the city!" Ma Wu ran to the front of him with a somewhat embarrassed face and reported.

"What's the situation?" Li Yuanji asked subconsciously.

"I ...... Just look at it, I really don't know what to say. Ma Wu's face was embarrassed, with a faint sense of anger.

After the Tuli Khan withdrew his troops and successfully entered Fengzhou, Li Yuanji was not really careless, and the first thing he did after entering the city was to order a search of the whole city to ensure that there were no hidden dangers.

Fengzhou is not big, but it is not small, at least there are three or four lanes in Chang'an, and the layout of the city is also square, except for a few buildings, most of them are mainly rammed earth structures.

After turning around, Li Yuanji came to the vicinity of the Fengzhou Governor's Mansion, and several private houses were surrounded by many soldiers, and all of them had the same solemn expressions on their faces.

Stepping into a courtyard, Li Yuanji clenched his fists tightly.

Dozens of women crowded in the courtyard, their clothes had not been washed for an unknown amount of time, and their faces were covered with dust, and the women hugged each other, trembling all over, and even the sight of people would produce an inexplicable sense of fear.

"The Turki Khan only gave them one meal a day, only enough for five people, and they said that there were about four or five hundred people who came together, and they didn't know where they were held, and people were taken out almost every day, but none of those who went out ever came back. They searched the whole city, and found less than two hundred women, and ...... And they're all older. Ma Wu's eyes were red, and he said with anger.

He just didn't want to, he also knew where the disappeared people had gone, and that kind of thing was not unusual at all for the Turks.

Although they also knew that they couldn't do anything about it, this was the war, this was the current situation in the border area, but when they saw this scene with their own eyes, they still couldn't bear the pain in their hearts.

"Find a yard for them alone, fetch some water to wipe their bodies, change their clothes, give less food for the time being, and count their provenances, those who are willing to go back, and then go back with our logistics, and those who don't want to go back will stay for the time being, so that they can live here with peace of mind!" Li Yuanji was also angry, his anger was no less than anyone else's, but as a commander-in-chief, he couldn't lose his sanity.

"Your Highness! Take your brethren and fight against the Tulina bastards! Ma Wu suddenly knelt on one knee and begged bitterly.

"Yes, Your Highness, the bastard of Tuli is too hateful, and no one can bear it."

"Even if we die in battle, we are willing, just to be worthy of this conscience."

“……”

More and more sergeants joined the ranks of the soldiers, and in a short time, almost all the sergeants knelt down.

Looking at the women who were still in fear, looking at these sergeants who fought in order to be worthy of their conscience, Li Yuanji felt that his heart was dripping blood.

"Do what you are told!" Dropping four words, Li Yuanji left the courtyard without looking back.

……

Far away in the north of the desert, in February, it is still a whole white expanse, icy and snowy, so that people are reluctant to leave their tents.

In the royal tent of a tribe, a middle-aged man dressed as a Han Chinese is sitting on the guest seat, and the beef and mutton and wine placed in front of him have not been touched.

"Why doesn't Tang Envoy eat it? Isn't it unappetizing? Yi Nan sat on the main seat, his body casually exuded a kingly atmosphere, and asked the man in Hanfu hospitably.

"It's not that you don't eat, it's not that it's unappetizing, it's just that you want to eat this meal with Khan in Fengzhou!" The middle-aged man smiled and said calmly.

"Wei Dao, if you have something to say, just say it directly, and go around these twists and turns like a girl." The Turkic general sitting opposite Wei Dao pointed at Wei Dao with an unhappy face and scolded.

"Tie Li, Hugh is rude!" Yi Nan scolded his generals sharply, but the expression on his face did not show a trace of sternness.

Wei Dao didn't care about this, these desert barbarians were just uncivilized barbarian tribes after all.

took out a silk cloth from his arms, stood up and stood in the center of the big tent, and said with a stern face: "His Majesty the Emperor of the Tang Dynasty canonized the Khan as the True Pearl Viga Khan!" ”

Yi Nan's indifferent face finally turned solemn, as if he was thinking, and after a few breaths, Yi Nan slowly stood up and walked down from the main seat.

"Yi Nan is willing to accept the canonization of the Tang Emperor!" After thinking about it several times, Yi Nan finally accepted Li Shimin's canonization.

This is unexpected, but it is also expected, accepting the canonization, which is equivalent to belonging to the Tang Dynasty, Yi Nan has an anti-Turkic heart, and accepted the persuasion of the Tang envoy, and secretly did some things, Yi Nan, who is not strong, can only accept the canonization of the Tang Emperor for the time being.

Yi Nan, who only has 70,000 troops, will either be annexed by Jieli, or he can only unite with Datang to kill Jieli.

After receiving the edict, Yi Nan's complexion finally recovered again, and with this edict, his heart was finally a little more steady.

"The king of Qi led an army of 200,000 to Fengzhou, without a fight and frightened off the Tuli Khan, and soon he could go north and confront the Jieli soldiers, did the Khan determine when to send troops?" Wei Dao continued, with an old monk's calmness, defeating Jieli, in his opinion, it could only be a matter of time.

"It will take some time to send troops, and it will be difficult for Ben Khan alone to resist Jieli's attack, and in a month, a month, several other troops can be persuaded to send troops with Ben Khan." Yi Nan explained with a difficult face.

"A month later, I'm afraid that the King of Qi has already led his army to the Turkic tent!" Wei Dao snorted coldly, and his attitude changed suddenly.

"Ben Khan will do it as soon as possible, Tang Envoy, please rest assured!" Yi Nan didn't get angry, but just explained again and again.

"I hope you can send troops before the king of Qi arrives at the Turkic tent, otherwise, the temper of the king of Qi is not very good, you have to be mentally prepared!" Wei Dao reminded him unceremoniously, then turned around and left.

"Phew...... What is it? Isn't it just the identity of a Tang envoy? What's so? Tie Li spat at Wei Dao's distant figure, scolding with an unhappy face.

"Father, when are we going to send troops?" Yi Nan's sister-in-law, Bazhuo, asked bluntly.

Yi Nan looked back at his sister-in-law, although he was an adult, his mind was like a child, he had no scheming, and a sweat position could stimulate his ambitions, which was not a suitable candidate for an heir.
