At the mouth of the Longwu River, the river is fast.

Under the warm and bright sunshine, Li Xuan stood at the head of the bridge on the south bank, watching the bags of grain being quickly transported to colleagues, and nodded slightly.

Looking sideways at Li Yi on the side, Li Xuan asked in a low voice, "Have you seen it, how is the cable force?" ”

"It's going to last a month and a half." Li Yi walked to the wooden stake at the head of the bridge, grabbed a fist-thick cable with all his might, and the water splashed underneath.

Pointing to the wet cable, Li Yi looked at Li Xuan and said: "Usiza was also doing a long-term move at the beginning, as long as he captured the north bank, he would immediately send his followers to the north bank, block reinforcements in the east, attack Guide in the west, and then occupy Jianzha forever." ”

"At that point, maybe I'll be forced to Jishi Town." Li Xuan smiled lightly and said, "It is precisely because he was ambitious at that time that I have a chance to take here, otherwise as long as he sticks to it, I will have no chance to wait." ”

Li Yi was slightly stunned, and then nodded in agreement.

Li Xuan is right, when a person has no desire, he is invulnerable, but when he has desire and ambition, he has the opportunity to be taken advantage of.

If he himself guards the south bank of the Yellow River, then how to find a way to cross the river is Li Xuan's responsibility.

At that time, Li Xuan said that he had to take a bigger risk.

However, Uxiza coveted the merit of capturing the north bank, cut off the army's food route, and even wanted to kill Li Xuan, take Jianzha, and work together to annihilate Li Jinxing's tens of thousands of troops.

It was this feat, which could make him go further, and sent him directly to hell.

"It is precisely because of his ambition that he used the same rope-making method as the prince, with tung oil soaked, soaked in water, naturally there is no need to worry about being attacked by fire, but he didn't expect that our army would be able to kill it." Li Yi couldn't help but sigh.

If Usiza hadn't underestimated Li Xuan too much, he wouldn't have died here.

"Don't talk about him." Li Xuan's expression became solemn, and then said: "It's okay for the rest, in a month and a half, the cables must be completely replaced, even the rafts must be replaced, if the war is not big at that time, it will be enough, once the war is urgent, if there is a situation here, not to mention the delay, it is likely to kill people." ”

"Therefore, the last general suggested that waterwheels be built on the north and south banks at the same time, and with the help of waterwheels, increase the transportation capacity, so that the south bank will concentrate enough grain, and the north and south will dismantle the old bridges and lay new bridges at the same time, so that time will not be delayed." Li Yi bowed his hand slightly, and Li Xuan's improvement in the grain road was seen by many people, and they actively studied and transformed.

"Yes!" Li Xuan nodded in agreement, and then said: "Within three months, it can be like this, but once the weather enters winter, it will be a new trouble." ”

Li Yi's face suddenly became solemn, his hand pressed on the stake, and his eyes were thoughtful.

After all, they are not here for a while, but it is even very likely that if they do not break through Wuhai in the future, they will not have a chance to transfer back to Chang'an, so the problem of winter must be taken into account.

"In winter, the weather is cold, although the water of the Yellow River will not condense, but the cold water will definitely constitute an obstacle to the raft bridge, if you say that it is calculated, it is enough to use a ship to transport food, but the flow of people is to be greatly restricted, after all, colleagues, in the future, we will wait for the place to eat."

Li Xuan's words made Li Yi's expression more and more solemn.

Yu Ze is Li Xuan's confidant, and he was appointed as the county commander of Tongren, which means that in the future, once the supply of grain and grass in the follow-up of the imperial court is not enough, then they must find a way to solve the grain and grass in Tongren, so the matter of Tongren is actually related to the logistics of the entire 5,000-strong army of the right guard.

"It's still about building a permanent bridge." Speaking of this, Li Xuan paused slightly, looked at Li Yi and said, "What do you think, how about building a suspension bridge, and how about the kind of suspension bridge used to defend the city?" ”

"Drawbridge?" Li Yi's mind immediately came up with the drawbridge that could be hoisted and retracted when defending the city.

Li Xuan nodded and said: "The Yellow River is too long, the distance of more than one hundred and thirty zhang is enough to make anyone who will be a prisoner desperate, but if it is separated in half, the north and south will build bridge piers on the bank, and the cables will be connected, and then the suspension bridge will be opened and closed by a water wheel, and the wooden bridge will be retracted by steps."

Suspension bridges do not need to be used for a long time, in the summer, use raft bridges, in winter, use suspension bridges, suspension bridges to cross people, raft bridges to cross grain.

In the event of a non-repair, as long as you prepare enough food and grass in advance, even if you encounter an emergency, you can do it without delay. ”

"Then we need to start preparing for this from now on." Li Yi couldn't help but nodded, this method does have a feasible way.

"Let's build a waterwheel first, there are too many problems in repairing the bridge, and we still have to report to the Ministry of Industry, what we can do now is to store the grain." Li Xuan paused for a moment, and then said in a low voice: "It's only early July now, and when it comes to September, before the autumn harvest in the Northland, I'm afraid it's the time when the food supply is tight, you have to know in your heart." ”

"The last will know." Li Yi was transferred to Li Xuan's command from Youzhou, and he knew about the drought in the eastern part of Youyan Mountain.

Now I think that before the autumn harvest in September, the shortage of tax grain will greatly affect the food supply of the army.

"I just hope that the fighting will stop then." Li Xuan's eyes fell on the north bank, at this time, two fast horses came at a rapid point, and then were directly stopped at the north bank bridgehead, Li Xuan looked at Li Yi and said, "Let's go, go over and see, what's going on?" ”

"Whoa!" Li Yi nodded immediately, and then followed Li Xuan across the raft bridge quickly.

At the head of the bridge, the two Qianniu guards immediately bowed to Li Xuan: "Lord Wang, the Sun Moon Mountain is urgent, the army has passed the Nanshan Pass, and the general asks the prince to go to the Nile Lake immediately to discuss matters." ”

"The army has already left the Nanshan Gorge." Li Xuan was stunned for a moment, and immediately said, "Okay, let's leave now." ”

Li Xuan immediately turned over and got on the horse, took Li Yi, and two teams of Jin Wuwei and Qianniuwei went straight to Guide.

Along the way, Li Xuan's expression didn't have much joy, because this time was a few days earlier than he originally expected.

After passing through the virtues, Li Xuan soon came to the mouth of the valley on the south bank of the Nile Lake, outside the heavy camp.

Glancing at the right leading guard and right guard who were cleaning up the battlefield, Li Xuan's face was already solemn.

Going, a large row of twenty catapults was placed at the mouth of the valley, aimed at the farmland on both sides of the Nile, and there were an unknown number of rolling stones and soldiers and horses killed in battle.

Li Xuan couldn't help but sigh, fortunately, they were lucky to take the valley mouth on the east side of the Nile Lake that day, and they were able to let the catapults and crossbow machines put in, otherwise they didn't know how many people would die under the fierce attack of the Tubo people regardless of losses.

"Lord Wang!" Yan Tao, who was dressed in red clothes and gold armor, was guarding outside the big tent, waiting for Li Xuan.

Looking at the Dao Dao knife marks on the armor on his body, Li Xuan patted him on the shoulder and said softly, "It's hard work." ”

Li Xuan was originally transferred to the Nile front line on the bright side, but in fact, Li Xuan has always been behind Longwu Village.

The Li Xuan seen by the Tubo people was actually just Yan Tao dressed up here, and the two thousand Hangzhou soldiers transferred by Li Xuan's men were actually the ones he had always commanded here.

can make the Tubo people always affirm that he is Li Xuan, and Yan Tao, the fake "Li Xuan", can imagine how much he has paid.

"There are a lot of military achievements under him, this is the position of a general?" Yan Tao looked at Li Xuan with some hope.

Li Xuan smiled and said, "Don't worry, this king has already mentioned it before, next, you will sort out the merits, and this king will be directly sent to the military department and His Majesty." ”

"Thank you, Your Majesty." Yan Tao's face was full of joy.

Everyone knows that Li Xuan has a piece of music sent to Chang'an in three days, if he can take advantage of Li Xuan's recital and appear in front of the emperor, then the future is naturally immeasurable.

Yan Tao actually appeared on Li Xuan's recital a long time ago, but the name that the emperor saw every day was a lot of buckets.

It's hard to look at, let alone memorize.

Only by repeatedly appearing in front of the emperor will he be remembered by the emperor.

Li Xuan's face converged, then he looked at the big tent in front of him, and said calmly, "Let's go." ”

"Whoa!" Yan Tao followed behind Li Xuan and entered the big tent directly.

In the big tent, Li Jinxing sat behind the central table, and on both sides stood Li Qing, the general of the right leading guard, Li Duozuo, the general of the right leading guard, and other generals and captains.

Li Xuan entered the big tent and immediately bowed his hand and said, "My subordinates have seen the general." ”

"The prince has arrived, please take a seat!" Li Jinxing raised his hand a little tiredly.

"Thank you, General." Li Xuan walked to the side and sat down, then looked at Li Jinxing and asked, "General, the people of Tubo seem to be very quiet today?" ”

"Not only today, yesterday, in the afternoon, the Tubo people retreated, and after three consecutive days of strong attack, the Tubo people began to rein in their actions." A trace of worry flashed on the face of Li Qing, the general of the right leading army, Li Xuan raised his eyebrows, and immediately said: "In this way, they also received the news of the loss of Nanshan Canyon?" ”

"It should be so, but in the Nanshan Valley, it seems that in the last section, the Tubo people have the intention of giving up, but on the other side of the Nile Lake, it seems that there are too many losses, and they have begun to rein in their hands." The uncertainty in Li Duozuo's words is a bit too much.

Li Xuan waved his hand very directly: "They are not giving up, they are restraining their hands and feet, stretching the battle line, waiting for work, and preparing to hit us hard." ”

After a pause, Li Xuan sneered and said: "This is actually a strategy to lure the enemy into the depths, the Tubo people can give up the Nanshan Gorge, but they will never give up the Nile Lake, once the Tao River and the Lanshan Road converge, and the grain and grass are continuously supplied, then the Tubo people's advantage around Qinghai Lake will be wiped out, so once we are hit, they will immediately counterattack." ”

"But we must break the Tibetan army at the western mouth of the Nile." Li Jinxing looked at Li Xuan and asked seriously, "Does the prince have a good plan?" ”

Li Xuan's face was solemn, he glanced at everyone in the tent, and then said: "It's not that there is no way, but what is the specific effect, it depends on the right time and place?" ”

"The prince is talking about using a boat?" Yan Tao was the first to understand the meaning of Li Xuan's words.

The so-called time and place are favorable, and now they are in the lower reaches of the Nile, and there is no location, so there is only the right time.

Li Xuan's most famous means is nothing more than taking advantage of the wind.

In this northwest road, it is not easy to start a fire, and the rest is the wind.

Li Xuan nodded and said seriously: "Compared with other Yellow River waterways, although the Nile Lake is turbulent, it is still too gentle. ”

Li Jinxing followed up and asked, "Where does the wind come from?" Where did the ship come from? ”

"Three days after the wind, the ship has reached the mouth of the Longwu River, and it can be transferred at any time."

After Li Xuan finished speaking, he suddenly frowned, turned his head to look in the direction of Chang'an, and felt a little uneasy in his heart.
