The Sui army immediately set off to march to Goguryeo after encircling and suppressing the Khitan, Li Chun, the squire of the Ministry of Works, had already built three pontoon bridges on the Liaoshui River, three days later, 80,000 Sui troops crossed the Liaoshui through three pontoon bridges, because the road leading to the Wugu City in Liaodong City had been blocked by a landslide, and it had not been dredged for a while, and the 80,000 Sui army was assembled in Suicheng.

Suicheng is located on the east bank of the Liaoshui estuary, that is, today's Yingkou in Liaoning, they will cross the Liaodong Peninsula from here, arrive at the Black Bone City, Suicheng is also the shortest road from the Black Bone City, compared with the Liaodong City to the Black Bone City to shorten more than 150 miles, only need to march three days to reach the Black Bone City.

It's just that Suicheng Road is a mountain road, and the road is too narrow and rugged to pass through heavy vehicles, so although it is close to Wugu City, it is not the main direction of attack.

However, it was not a problem for the Sui army, all the baggage and materials were carried on the big ship and went by sea, bypassing the Liaodong Peninsula to the mouth of the Yalu River, while the main force of the Sui army marched lightly, and each soldier carried five days' dry food along the Suicheng Road and marched quickly in the direction of Wugucheng.

Three days later, a mighty army of tens of thousands arrived at the Black Bone City.

In one of the largest stone buildings in the black bones, Zhang Xuan stood in front of the simple sand table and listened intently to Fang Xuanling's report.

Fang Xuanling stayed in Wugu City, he was responsible for commanding the Sui army to intercept the Goguryeo reinforcements to the north, before that, Du Ruhui had simply told him the situation in Liaodong, but at this time he had not had time to express his opinion on the Liaodong campaign, Zhang Xuan was waiting for him to report on the Goguryeo reinforcements.

"The Goguryeo army was about 50,000 people, and the military camp was located on the banks of the Sasu River."

Fang Xuanling pointed to a small river in the middle of Yalushui with a wooden pole: "The big camp is here, less than three miles away from Yalushui, they don't seem to have any baggage logistics, so I have this big camp set up a long time ago, although it is called a big camp, but the board wall is very strong, and it is no different from a city." ”

"Do they have warships?" Jang Hyun asked, staring at the Banqiang camp.

"Yes!"

Fang Xuanling said with certainty: "At first, there were more than 100 ships, but they didn't expect the sharpness of our navy, most of them were destroyed in the first battle, and there were about ten left, all of which were medium-sized ships of about 500 stones, and they were currently hiding in the barracks. ”

"Wait—"

Zhang Xuan suddenly noticed something and was anxious

Asked: "Is their barracks across the river?" ”

Fang Xuanling nodded, he knew what Zhang Xuan was thinking, and said with a smile: "We also considered diving into the barracks from underwater, but it didn't work, they installed two river grates in the river, both front and rear, the water ghosts can't sneak in, and there are sentries on the shore to closely monitor, and they will be discovered as soon as they show up, and the three water ghosts we sent almost can't come back." ”

Zhang Xuan pondered for a moment, and then said, "Strategist, please continue." ”

Fang Xuanling said again: "Just some time ago, part of the army in the military camp was preparing to return to Pyongyang, but after two days of walking, we came back, and we caught a spy, only to learn that this army has two main generals, one is called Gao Yanshou, who is the Goguryeo royal family, and the other is called Yuanqinggong, which is the brother of Yuan Taizuo, and this army is actually composed of two factions of Goguryeo. ”

At this time, Du Ruhui next to him asked: "Since it is two factional armies, can we divide them and annihilate them?" ”

"It's a real idea, but it's a bit unrealistic."

"Why?" Jaung Hyun asked puzzled.

"Because the military rations are controlled by Gao Yanshou, Yuanqing Palace cannot go out independently, and can only rely on Gao Yanshou, so although the two armies belong to different factions, they are tied together by the military rations."

"Speaking of which, the army that was going to return to Pyongyang some time ago should be the army of Wongyeong Palace, right!" Du Ruhan said with a smile.

"I also think so, Gao Yanshou will not give up control of the grain."

Zhang Xuan paced back and forth in the big tent with his hands in his hands, he had been experienced in a hundred battles, he was used to winning with strategy, he did not like to fight hard, he pondered for a long time, he asked: "Is the camp tent of the enemy soldiers a stone house?" ”

"It's the big tent of the Sui army, and it was lost in Liaodong back then."

"If it's a big tent, it should be able to attack with fire, do you think it's feasible?"

Fang Xuanling shook his head, "Many generals have proposed this plan, but Goguryeo's defense is very strict, there is a buffer belt around it, rockets are not good, and the distance of the trebuchet is enough, but if our trebuchet appears, their big tent will definitely be put away, and the fire attack will be targetless, but ......"

"But what?" Zhang Xuan heard what Fang Xuanling said.

Fang Xuanling smiled and said: "Although Goguryeo is well defended, there is a loophole in the structure of their camp, which we can exploit, and I have been waiting for His Highness to come back and discuss before deciding." ”

Fang Xuanling whispered a few words to Zhang Xuan, and said what they needed to prepare. Zhang Xuan suddenly said happily: "I think this direction is feasible, you can give it a try, as for the things that are needed, I will let Li Chun make these things, I believe he will not let me down." ”

The two said a few more words, and Zhang Xuan remembered something and asked, "How is the situation on General Li's side?" ”

General Li is Li Jing, who is currently leading 5,000 troops to garrison the domestic city, while the old general Lai Hu'er is leading a fleet to patrol the Yalu River, and Zhang Xuan is asking about the situation in the inner city.

"The situation on General Li's side is fine, we have established a flying pigeon message, and we can contact you at any time."

One sentence reminded Zhang Xuan, and he hurriedly said: "Speaking of the take-off pigeon biography, I think of one thing, the road between Wugu City and Liaodong City was blocked, what is the situation now?" ”

"The road has indeed been blocked, I also went to the scene to see, the whole mountain collapsed in half, our more than 20 ox carts were buried underneath, the collapsed mountain is too large, more than ten miles, filling the entire valley, it is not realistic to dig the road, now we can only consider avoiding another road."

"Have you decided on a plan?" Jang Hyun asked.

The terrain of Goguryeo is too complicated, either steep mountain roads or dense forests, and the traffic is very inconvenient.

Fang Xuanling sent someone to find Li Kai to join the army, and he is currently in charge of this matter, he has just returned, and he has not yet reported the new road to Fang Xuanling.

After a while, Li Kai, who joined the army, walked into the big tent quickly, bowed and saluted, "Gongcao joins the army and engages in Li Kai to see His Royal Highness the King of Qi!" ”

Zhang Xuan saw that he was about twenty years old, dark and thin, looking very much like Li Chun, and he was also surnamed Li, so he asked with a smile: "Is there anything related to Li Shilang of the Ministry of Industry?" ”

"Back to His Royal Highness, Li Shilang of the Ministry of Industry is my father."

Zhang Xuan laughed, he was not mistaken, he was really Li Chun's son, and he was actually in charge of the project, Zhang Xuan praised: "Sure enough, it is a tiger father without a dog, and your father is also here with the army, and your father and son can reunite later." ”

"Thank you Your Highness for your concern!"

Zhang Xuan nodded, and then asked, "Talk about the road between Wugu City and Liaodong City, Master Fang said that you are in charge." ”

"Back to Your Highness, the landslide is located south of Liaodong City-"

Zhang Xuan waved his hand to interrupt him, "I already know this, Master Fang said that he can only find another way, I want to know if the plan for the new road has been determined." ”

"Back to Your Highness, the preliminary plan is basically decided."

Li Kai walked to the sand table and pointed to the east of the old road with a wooden pole: "I have considered two plans for the new road, plan A is located about fifty miles east of the old road, and plan B is located eighty miles east of the road, these two plans have their own advantages and disadvantages, plan A is three hundred and fifty miles away from Liaodong City, which is similar to the old road, but there are more mountain roads and it is more difficult to walk, and plan B is a bow back arc, about five hundred and twenty miles away from Liaodong City, but basically it is a valley, and a flat road can be built after opening up. ”

"So which option do you prefer?" Zhang Xuan asked with a smile.

"The lowly position tends to plan B, although it is far away from Liaodong City and Wugu City, but it is a flat road, which is very rare, the time spent on the march is less, and you can take a big car, and more importantly, the domestic city can also use this road, it is only a hundred miles away from the domestic city, and the lowly position will simply build it into a straight road, until it reaches Yalu Water, and then build two branches on the Yalu River, one to the east leads to the domestic city, and the west one leads to the Black Bone City, it looks like a crossbow, and then"

Speaking of this, he suddenly felt that he was talking too much, and he couldn't help but stop talking, and scratched the back of his head a little embarrassed.

Zhang Xuan heard his full attention, and when he saw him stop abruptly, he urged: "Keep talking!" ”

Fang Xuanling next to him was also interested, he hurriedly found a few wooden sticks, and according to Li Kai's description, the wooden strips were laid into a 'Ding' shape, and the shape of this straight road really looked like a crossbow.

Li Kai pointed at the tip of the crossbow with a wooden pole and said: "I consider building a fortified city here, and at the same time build a wharf, so that the military and people's livelihood can be taken into account." ”

Zhang Xuan nodded slowly, and said that his heart was up, and convenient transportation was the key to controlling Goguryeo, "Plan B can be accepted!" Jang Hyun thought for a moment and asked, "Can we also build a pier on the opposite side and extend the straight road all the way to Pyongyang?" ”

"I'll go to inspect tomorrow and make a plan as soon as possible."

"There's no need to rush!"

Zhang Xuan said with a smile: "That's just a long-term plan, the top priority is to build the road from Wugu City to Liaodong City, what do you think is the biggest difficulty?" ”

Li Kai glanced at Fang Xuanling, and Fang Xuanling said with a smile: "If the plan can be determined, then there will only be a lack of people to build roads." ”

"There is no problem with the people, they use the pawns to work, pave roads, mine, and all the pawns do these two things."

Zhang Xuan smiled at Li Kai again: "From now on, when you take the position of Sima of Liaodong County, you have to consider the long-term plan for road construction, the one-year plan, the three-year plan, the five-year plan, and the ten-year plan, how much manpower and material resources are needed?" How to connect with the hinterland of the Central Plains? How to implement it step by step? Not only by land, but also by water, my request is that if there is a rebellion in Pyongyang in 10 years, the troops stationed in Liaodong City can reach Pyongyang in three days, and the reinforcements from Youju will arrive in Pyongyang in six days, do you understand? ”

Li Kai had a dreamlike feeling, as if a window had opened in front of him, allowing him to see the scenery he had never seen before, the five-year plan, the ten-year plan, start doing it now, and then implement it step by step, he was very excited in his heart, "I understand the humble position, I will definitely be able to do it!" ”

Zhang Xuan patted him on the shoulder and said with a smile: "After completing this ten-year plan for Liaodong, I will appoint you as the squire of the Ministry of Industry and inherit your father's position." ”

"Then my father—"

"Don't worry! Your father will soon cease to be a squire in the Ministry of Works. Jang Hyun laughed meaningfully. (To be continued.) )
