The pressure on Lu Yao was far heavier than his subordinate generals knew.

The total number of the Xiongnu army was about 40,000. Excluding the several groups of men and horses distributed in Jiexiu, Qixian and other places, Lu Yao estimated that the actual number of troops they could use on the main battlefield was about 28,000. This number was close to three times the main force of the Jinyang Army led by Liu Kun. Yue Shi Gong led his troops to confront it head-on, bearing tremendous pressure.

Early yesterday morning, the messenger reported Liu Kun's military order: The main force of the Jinyang army and the army of Liu Yuan, the king of Han, fought a series of 'fierce' battles, and both sides suffered extremely heavy casualties; therefore, the troops that were gathered in the rear one after another will be transferred to Xicheng, and no reinforcements will be sent to Qixian. The war in Qi County is all in charge of Lu Yao.

Yue Shigong was relieved to let a new general like Lu Yao take on the attack and defense of a strategic direction, which certainly reflected his extraordinary temperament in employing people; But for Lu Yao, the pressure is really great - he must rely on the strength of less than 1,500 people to resist the more than 5,000 Huns.

The strength of the Xiongnu army was superior in strength, and the general degree of 'elite' was also higher than that of the Jin soldiers; the weakness was that they crossed the Jiexiu garrison of the Jin army and went north, and the food supply was very problematic, so it was not conducive to a protracted war.

Contrary to the Xiongnu, the weakness of the Jin army was precisely their strength and combat effectiveness. No matter how confident Lu Yao was, he would not think that the Jin army under him had the ability to confront the Hu people head-on; However, the Jin army occupied a favorable position, relying on many high mountains and dense forests, lakes and marshes and rivers on the east side of Zhaoyu Qi, sitting on two important places in Moi Mountain and Quanfang Mountain, and holding the pass of Tuanbai Valley, forming a strong defense line.

However, the transfer of the main forces of the Huns broke the delicate balance of power between the two armies of the past few days. Without knowing the enemy's target, it is impossible to organize a defense against 'sex'. The geographical advantage that the Jin army originally relied on faltered, making the battle situation fall into an extremely dangerous situation.

What was the goal of the Huns? The two armies of the Jin army were very well defended at Moshan and Quanfang Mountain, which were enough to withstand the siege of more than five times the number of troops, and this did not change due to the dense fog. Therefore, the Huns took advantage of the fog to move, and their purpose should not be the Jin army in the Moraine Mountain and the Exhaustion Mountain.

So, could it be that their goal is Tuanbai Valley? That's even less realistic. There are only four roads leading to the valley, and apart from the main road that passes at the foot of the mountain, three of the small roads are so rugged that they cannot accommodate a large army to cross them. What's more, all four roads were under the close surveillance of the Jin army, and the Huns could not sneak across them at all.

Neither Moi Mountain and Jifang Mountain, nor Tuanbai Valley, so what is the goal of the Huns?

What did the Huns intend? Where will they be now? What will they do next? How should our military respond? Lu Yao pondered and thought repeatedly, only to feel that the headache was split, and the "sex" took the map again to take a closer look.

This map is often used in the military, but in Lu Yao's opinion, it is too brief. Many mountains and rivers are only scribbled by a few strokes, and there are many errors in the distance and distance of the road in between. Lu Yaosuo called the guide in the army to ask, took his own pen, and first filled in the relevant landforms on the map one by one.

The topography of Qi County is high in the southeast and low in the northwest, with mountains, hills, plains, lakes and marshes, and rivers, and the terrain is complex and changeable. At this moment, the moraine mountain where he is located is one of the many peaks in the southern part of Qi County. The two armies of the Jin army were stationed in the Moraine Mountain and the opposite side of the Jiefang Mountain, not only the official road leading to the north, but also the other three passable north-south paths were also under the overlook of the Jin army, which was difficult to cross.

The official road that runs through the north and south of Qi County passes between the two mountains and leads to the county seat of Qi County. The residents of the county town have all moved to Jinyang a long time ago, leaving only an empty city at the moment. Further northwest of the official road is the important pass Tuanbai Valley. To the north of Tuanbai Valley is the wilderness of a horse and a flat river, and there is no obstacle to Jinyang directly.

Not far from the moraine mountain is the dragon boat water, also known as Hou Jiashui. The original east-west river channel was blocked by the moraine mountain, made a bend and flowed northward, and finally rushed out of the mountains, and joined the Fenshui in the swampy area more than 20 miles north of the moraine mountain.

Lu Yao frowned. Qi County is where the right part of the Xiongnu is located, so they are very clear about the geography here. But Lu Yao has been in the army in Bingzhou for many years, and there are locals in the army as township guides, and his understanding of the terrain of Qi County is not inferior to that of the Hu people. The problem was that the Momian Mountain and the Quanfang Mountain, which the Jin army was guarding, were indeed important places, and he really couldn't imagine where the main force of the Hu people had moved.

He sighed imperceptibly and continued to add to the map.

Lutai Mountain is in the south of Moi Mountain, fifteen miles away from Jingling in the south; It is about 40 miles away from the moraine mountain in the north, and if you take the trail, it will be farther. This mountain is steep and steep, and it is the watershed between Qi County and Wu Township. There is a Hucheng Valley in the mountain, and many streams gather in the valley to form a river, which is called Hugu Water. Hugu water flows eastward for dozens of miles, joins the 'hole' whirlpool in an unnamed lake at the easternmost end of Qi County, and then turns to the northwest, twists and turns along the way, and finally joins Fenshui in the south of Tuanbai Valley.

At this point, Lu Yao was shocked.

Hu Gu Shui!

The amount of water in Hugu is very small, and the river is winding and the drop is very large, so it is impossible to sail at all, so Lu Yao did not pay attention to it at first. But...... If the soldiers of the Hu people are ruthless and brave enough, they can weave a raft and float down the river! Although this river has made a huge circle to the east, there is a lake at the confluence with the whirlpool of the 'cave' for resting, second, the amount of water downstream is gradually increasing, enough to carry a large boat, and third, along the way, it can avoid the surveillance of the Jin army of Lutai Mountain and Moi Mountain by means of complex landforms, and reach the last key pass in the southeast of Jinyang, Tuanbai Valley!

Yes, it must be! Shi Le, the main general of the Hu people, was born as a horse thief in Hebei. Isn't this kind of use of troops in danger of winning in line with the bold and reckless path of horse thieves? Sure enough, it's a ruthless 'color'! Sure enough, it's an outlaw!

Lu Yao threw his pen up, strode out of the camp tent, and shouted loudly: "Pass the order, all the armies will reorganize their equipment, and pull out the camp within half an hour!" ”

The herald was just about to retreat, but Lu Yao suddenly shouted again: "Wait! ”

What if Shile hadn't taken the waterway of Hugushui? If the enemy is just going down the mountain through the thick fog and looking for a hidden place to lurk; Our army's 'chaotic' position has given the Hu people an opportunity to take advantage of? Lu Yao can fully imagine that after the Jin army leaves the Moshan camp, if it is attacked by the Hu people, it will definitely be a fiasco! It is very likely that Shi Le, the general of the Hu people, will do this, because the means of concealing and hiding and waiting for the opportunity to kill the enemy are not also the best routines of horse thieves?

Or maybe the Hu people didn't do anything in the end? It was tantamount to taking the initiative to give up the important strategic stronghold of Moshan just because of a guess, causing the Hu people to directly threaten and 'force' Tuanbai Valley. What kind of responsibility should be borne for such a major command omission?

Lu Yao frowned, and involuntarily paced back and forth in front of the tent. He pondered the enemy's possible movements, and before he knew it, he was sweating profusely, soaking through several layers of clothing.

"General! Checkmate! ”

Lu Yao raised his eyes to look, only to see Shen Jin and He Yun dismount and run quickly.

"General Qiyu, we are incompetent and have failed to discover where the main force of the Hu people is." Shen Jin said ashamedly.

Lu Yao interrupted Shen Jin's words and asked eagerly, "You have searched the terrain near Lutai Mountain, have you noticed anything unusual about Hu Gushui's left and left?" ”

"Uh......" Shen Jin was speechless for a while. He glanced at He Yun and said hesitantly, "There is nothing special about it. The south bank of Hugushui is Lutai Mountain, and the Hu people have cut down the entire woodland by the water, so the field of vision is very broad, and we dare not get too close. ”

"The whole woodland?" Lu Yao suddenly shouted and asked, startling Shen Jin. Lu Yao asked solemnly: "If you think about it carefully, will they cut down trees to make a raft?" ”

Shen Jin's eyes lit up and exclaimed, "It's very likely!" ”

He Yun added: "We have seen a lot of scattered timber stranded on the shore downstream of Hugushui...... Most likely, they made up the remnants of the raft! ”

Lu Yao high-fived and shouted: "That's it!" ”

He was in a very excited mood and said loudly: "Pass my general order, immediately straighten out the weapons and armor, and abandon all other baggage." The whole army retreated from the back mountain to Longzhou Shui, and then boarded the boat to Tuanbai Valley! ”

"Boarding the ship?" Xue Tong, who came in a hurry, was surprised: "Daoming, are you 'mistaken'?" You have to take the road to Tuanbai Valley! The dragon boat water does not lead to Tuanbai Valley? ”

Lu Yao grabbed Xue Tong and pulled him to the table in the big tent: "Old Xue, come and see!" ”

Now that the movements of the Hu people have been determined, Lu Yao has already thought of a countermeasure in an instant. The enemy took the waterway of Hugushui to attack the Baigu Valley, although it was hidden, but the speed could not be fast. The Hugu River course is meandering, first going around a big bend to the east, and then turning all the way to the north, the distance is not less than 100 miles. Even if Hu Rentian set off as soon as he was released, he was only halfway at the moment.

The Jin army set off at this moment, if it takes the official road by land, after more than 60 miles to Tuanbai Valley, the mountain road is undulating and difficult, even if it is forced to march, it will take three hours. There is barely time in time, but in this case, it is very likely that you will collide with the Hu people in the wild south of Tuanbai Valley. The Hu people are numerous and fierce, and the field battle is not taken by Lu Yao.

"Therefore, we are going to go this way!" Lu Yao pointed heavily on the map. He had already inquired with the township guide to find out that after the dragon boat water bent in the moraine mountain, it almost went straight to the north, until about 20 miles of foreign exchange into Zhaoyu Qi.

Zhaoyu Qi is the world's well-known Daze since ancient times, the people who are near Wu County are called Wu Ze, and the ones in Qi County are called Qi Xu, and there are countless continuous lakes and marshes around it, and the terrain is extremely complex. On the east side of the mouth of the dragon boat water is a large area of silted shallows, and on the other side of the shoal, there is the water of the elephant valley that originates from the elephant valley.

At this point, the Xianggu water almost converges with the continuous swamp wetlands of Zhaoyuqi, and then goes all the way north, passing through the north mouth of the Tuanbai Valley, and finally joins the Fenshui in Yangyi County.

On this route, the distance to Tuanbai Valley is at most fifty miles; Not to mention that the dragon boat water and the elephant valley water are both large rivers with open channels, which are conducive to boating. Moreover, in order to prevent the Hu people from sneaking across the dragon boat water, the Jin army had already gathered all the ferries upstream and downstream to take care of them. The number of ships is calculated, which is enough to carry the land remote station. Although it was necessary to tow the boat from the dragon boat to the Xianggu water, it was not difficult to have hundreds of soldiers on board. A rough estimate of the itinerary will only take two hours to go around to the north of Tuanbai Valley, which will be one step ahead of the Hu people.

The art of war is like a game of chess; The contest on the screen is nothing more than a preemptive, and the same is true of the art of war. Lu Yao said confidently: "The Hu people take the waterway, and we also take the waterway!" This is called treating others in their own way! ”
