The first emperor of Tang Dynasty

Chapter 422 Building a floating bridge over the Liaohe River

Li Chengqian took it over and took a look, his eyes brightened.In any case, it never occurred to Xu Liang that he had such a complete plan long ago.

Li Chengqian asked Xu Liang, "This plan is feasible, but the difficulty lies in the erection of the pontoon bridge."

"Your Highness is really astute. The most difficult part of the whole plan is the pontoon. If there is no pontoon that allows the Four Elephant Guards to pass through, then everything will be empty talk."

"So before my subordinate came down, I had a long chat with Xiangli Wentian all night. Finally, I found the most suitable plan for erecting a pontoon bridge." Xu Liang said in front of the opposing floor.

"I don't know what kind of pontoon bridge it is that can make you and Xiangli Wentian admire it so much." Li Chengqian couldn't help being interested, and asked Xu Liang.

"The weather is not cold now, so it's not difficult to send someone to sneak across the Liaohe River. So it's not impossible to fix the two ropes on the opposite bank," Xu Liang said.

It turns out that Xu Liang's pontoon bridge was tied to the opposite bank with several giant ropes.Then secure the plank on the rope.When in use, use the foot plate to shake the rope out of the river.The pontoon bridge is naturally considered a success.

And such a pontoon has one of the biggest advantages, that is, it is always hidden in the river when it is not in use.It is difficult to be discovered by the other party.

But what Xu Liang didn't expect was that Li Chengqian shook his head.And he said, "It's okay to walk on a pontoon bridge like yours alone, but how can you let the horses led by the Four Elephant Guards cross the Liao River?"

Li Chengqian's words made Xu Liang wake up like a dream. He really ignored the most important factor of war horses.If the Four Elephant Guards don't have war horses, then the combat power will not drop by one or two levels.

Seeing Xu Liang's disappointed expression, Yuchi Baolin said, "I think you are so capable, but after a long time, it turned out to be just talking on paper. I think I'm right, first cross the Liaohe River and go to Jili City."

As soon as Yuchi Baolin finished speaking, she was severely pinched by Princess Tulu beside her.Yuchi Baolin cried out in pain.

"Ma'am, if you have something to say, you can't just say it next time. It really hurts when you pinch your waist, do you know?" Yuchi Baolin said with a pitiful expression.

"I don't think it's wrong to pinch you at all. If I were your wife, I'd have to kick you a pig's head." Qin Huaidao said after glaring at Yuchi Baolin.

Yuchi Baolin scratched her head with a puzzled expression, not understanding why she became the target of public criticism.Even my own daughter-in-law secretly murdered me

Seeing Yuchi Baolin's rich expression, Li Chengqian shook his head helplessly and said, "Xu Liang's method won't work, but your method will do?"

"Of course, he, Xu Liang, can't use the suspension bridge. And his subordinates don't need any suspension bridges." Yuchi Baolin said with an expression that I won.

But just as he said that, he felt a pain in his buttocks.The whole person sat directly on the ground.At first, I thought it was my daughter-in-law Princess Tulu who did it.

After a closer look, it turned out that it was Qin Huaidao who kicked him.So he opened his mouth and said to Qin Huaidao: "I said, Brother Qin, why are you playing tricks behind your back?"

"I blame my brother for kicking you. You don't need a pontoon bridge, so you can fly across the Liaohe River?" Princess Tulu said after giving Yuchi Baolin a hard look.

This also made Yuchi Baolin understand what mistake she had made.I could only scratch my head, stood up and sat there without saying a word.

Seeing Yuchi Baolin's expression, Li Chengqian could only shake his head helplessly.Then he said, "My lord has a more suitable pontoon bridge plan. If it can be successful, not only the horses can go to the other side, but also the large supplies of our army can be transported there."

Hearing Li Chengqian's words, Xu Liang couldn't help being taken aback. He never dared to imagine that there would be such a pontoon bridge in this world.If there are, there will be no need to build stone arch bridges on great rivers in the future.

So he opened his mouth and asked Li Chengqian: "What is the structure of the pontoon bridge that His Highness mentioned, and why is it so effective?"

"I don't know if you still remember the Battle of Chibi in the Romance of the Three Kingdoms, what happened to Cao Cao's chain warships." Li Chengqian asked with a smile.

"Does Your Highness mean that we also build dozens of large boats and tie them together with iron chains. Then we will cross over with people and horses?" Yuchi Baolin didn't hold back, and asked Li Chengqian directly road.

"Shut up, if you dare to say another word. Believe it or not, my aunt will sew your mouth shut." Princess Tulu couldn't bear it anymore, her husband humiliated herself.

Seeing that his wife was really angry, Yuchi Baolin hurriedly shut up and sat there obediently.I was afraid that I couldn't help but say something again.

Li Chengqian also looked helpless, and then said: "As Xu Liang said, it is not difficult to send people to swim across the Liaohe River to pull a few ropes."

"It's just that what I want to install on the opponent is not just a rope, but four huge pulleys..." Afterwards, Li Chengqian explained his plan in detail.

In fact, Li Chengqian's solution is very difficult, that is to install a giant pulley on the opposite bank first.Then pass the rope through the pulley and tie it directly to the winch on this side.

Then use the horse to pull the winch here, so that the ropes in the Liaohe River can move in a regular cycle.Then fix the hoops on these ropes.

At the same time, people were arranged to make wooden boxes out of wood. The specifications of the wooden box were three meters long and one meter wide cuboid.And iron buckle and iron ring are installed on cuboid.

When waiting for use, buckle the iron buckle on the wooden box with the iron ring on the rope.Then connect the wooden box to the wooden box.

Then, with the angle of the foot plate, a three-meter-wide pontoon bridge will appear on the Liaohe River.And in order to reduce the pressure of water, one end of the wooden box is made upturned.

After Li Chengqian finished speaking, Xu Liang couldn't help showing admiration.He opened his mouth and said to Li Chengqian: "Your Highness's method is good. In this way, a pontoon bridge of more than one foot will appear on the Liao River. At that time, even war horses can pass smoothly."

"If that's the case, then quickly arrange for people to make wooden boxes. Remember to have enough quantity, after all, we are not building one pontoon bridge, but four." Li Chengqian nodded and said.

Li Chengqian's words couldn't help but make everyone's blood boil.After all, he secretly took advantage of the night and walked around behind the other party.Not to mention how cool that feeling is.

So in the next few days, everyone is busy.First, the craftsmen accompanying the army made huge pulleys and stirring plates.

Then, under the cover of night, they secretly erected a pontoon bridge at the fourth most dangerous place downstream.
