After Wei Wensheng returned to the Sui army camp in vain, he found that Yu Wenshu and others were arguing loudly with Yu Zhongwen.

It turned out that Yu Wenshu wanted to return because the food was exhausted, and those who held this opinion were Jing Yuanheng, the general of the Left Seventh Army, Zhang Jin, the general of the Right Twelfth Army, and Zhao Xiaocai, the general of the Right Ninth Army.

When the Sui army occupied the Black Bone City, although it captured some grain, but that food was quite a lot for the 10,000 defenders who were originally in the Black Bone City, but for the 300,000 Sui army, it could only cope with it for a few days, and now it has been eaten.

Zhao Xiaocai had a loud voice, and then said in his thunderous voice: "Now that the food is gone, if you go any further, the soldiers will break and flee, and if you return immediately, you can still survive by killing livestock." ”

Yu Zhongwen never spoke, and waited until everyone finished speaking, then glanced at the generals and said slowly: "Since things have developed to this point, then I will tell you clearly, Pyongyang is strong, and our tired army will definitely not be able to defeat it (the news of the naval division's attack on Pyongyang has not yet arrived), but if we return like this and do nothing, what kind of face do you have to meet the saint?" When the Holy One starts a fire, we will have to move! ”

Those generals, including Yu Wenshu, were silent after hearing Yu Wenzhong's last words, and Zhao Xiaocai unconsciously touched his somewhat cold neck.

Yuwen asked, "So, what are we going to do now?" ”

Yu Zhongwen said: "For today's plan, there is only one, which is to hunt down Yizhi Wende, make great contributions, and then return immediately, but this plan, we can't let the comforting envoy know, otherwise we will be busy in vain." ”

All the generals nodded and agreed, and immediately led the army across the Yalu water, Yuwen Shu took the initiative to ask Ying to be the pioneer because of the only credit for grabbing, and Yu Zhongwen saw that he was rarely so active, so he agreed.

Yu Wenshu then led his troops to chase after Yizhi Wende.

Yizhi Wende saw that the soldiers of the Sui Dynasty were hungry when he entered the Sui camp that day, so he deliberately made the Sui army tired. When Yuwenshu led his troops to chase, every time he fought with him, he immediately retreated, and Yuwenshu won seven battles in one day.

Yuwenshu's morale was greatly boosted, but unknowingly, he chased him to the bank of Sashui......

"God studies astronomy, calculates poor geography, defeats both high merit, and is content with the clouds." About fifty miles away from Yuwenshu's troops, it was the follow-up main force of the Sui army, and Yu Zhongwen was reciting this poem at this time.

While Yu Zhongwen chased Yizhiwen with a large army, he also sent a messenger to persuade him: "If you still have the intention of surrendering before, you can come back to surrender, I will definitely treat you with courtesy!" ”

However, Yizhi Wende didn't say anything, just replied to such a poem "Wende Sends Zhongwen Poems". (This poem is one of the earliest surviving poems on the Korean Peninsula.)

"The victory is high, and the wish is stopped." Yu Zhongwen read the last two sentences of this poem repeatedly, and suddenly felt a burst of upset.

Yu Zhongwen was born in a famous family, his grandfather was the general of the Zhu State and the Duke of Yan Guo Yu Jin in the Northern Zhou Dynasty, and Yu Zhongwen himself was even more famous at a young age, and he repeatedly made military exploits when he became an adult.

After the Sui Dynasty unified the world, only the northern Turks were troubled, but the strength was very strong, the strategy of the Sui to the Turks was a two-pronged diplomatic and military approach, and the diplomacy was mainly presided over by Changsun Sheng, which was divided into the current Western Turks and Eastern Turks, and militarily, it was several times to appoint and dismiss Yu Zhongwen as the marching marshal, and the Turks were at war, Yu Zhongwen lived up to expectations, and broke the Turks many times, which can be described as outstanding achievements.

Up to now, Yu Zhongwen's grace and honor can be said to have reached a peak.

Wei Wensheng hurriedly walked over at this time, "General Yu, General Yuwenshu's army has been chasing Sashui, the rain has not stopped recently, and Sashui has skyrocketed, I'm afraid Yizhi Wende will really set up an ambush there!" ”

"Oh? I know. Yu Zhongwen replied casually, but he was still muttering in his heart: "The victory is high, and the wish for contentment is stopped." If I make another meritorious service, will there be anything else that the Holy One can reward me? No, there's no more......"

Wei Wensheng originally came to ask Yu Zhongwen to ask Yuwen to return to the army, who knew that no matter what happened, Yu Zhongwen was calm and calm, but now it was as if he had lost his soul, and he suddenly didn't know what to do.

Yuwenshu led the army across Sashui and camped with the help of the mountain to wait for the army, and Yu Zhongwen also quickly led the army across Sashui and joined Yuwenshu.

Eulzhi Wende sent an envoy to deceive him and asked Yu Zhongwen: "The city of Pyongyang is steep and strong, although you have many men and horses, it will be difficult to take it. If the Sui army can retreat, I will definitely let the king Gao Yuan go to the court to meet the place where the emperor of the Sui Dynasty is located. ”

Yuwen Shu saw that the soldiers were tired and could no longer fight, and he had the credit of seven battles and seven victories, so he tried his best to agree with the retreat, Wei Wensheng, Xue Shixiong and others objected, but Yu Zhongwen expressed his approval of the retreat with blank eyes.

So the Sui army retreated in a phalanx, the Goryeo army outflanked and attacked from all directions, and the Sui army led the army to fight and go.

On July 14, the Sui army arrived at Sashui to cross the river, just half crossed, in an instant, shouting to kill the heavens, the Goryeo army suddenly attacked the rear of the Sui army from behind, and the general of the palace, Xin Shixiong, was shot dead by a stray arrow, causing a rout among the armies, which could not be stopped.

The 300,000 troops of the Sui Dynasty, when they came to this Sashui, because of the lack of food, were actually about to collapse, and the half-crossing attack of Yizhi Wende was just the last straw that broke the camel's back.

An army of 300,000 is no different from 300,000 sheep slaughtered once it is broken.

When Wei Wensheng crossed the Sashui a few days ago, because he had always remembered Li Yin's information, after crossing the Sashui, not only did he not dismantle the pontoon bridge, but also built a lot of pontoon bridges.

Until this time, Wei Wensheng didn't expect Yu Zhongwen to agree to withdraw at this time, and secondly, he didn't expect that the army behind the palace would collapse directly, which made him watch the battle situation erode, but fortunately, with those pontoon bridges before him, his troops quickly crossed Sashui and did not collapse.

The Sui army, which also did not break up, also had more than 10,000 people led by Wang Rengong, the second general of the 12th Army.

Yizhi Wende then led a large army to continue to pursue and kill the Sui army.

The soldiers of the Sui army fled, and ran to the edge of the Yalu water in one day and one night, traveling 450 miles. The still powerful general Wang Rengong was the rearguard, intercepting the Goryeo army and blocking them, buying enough time for the other armies to cross the river, but his troops also suffered heavy losses as a result.
