In the fourth year of the beginning of the Wei State, in May of the second year of the Chengguang of the Xia State, two days before the Wei King Tuoba Tao was about to attack the Xia State, the Xia King Helian Chang ordered the Plains Gonghe Lianding to send troops to Guanzhong, and confronted the Wei State Yicheng Wang Da Xijin in Chang'an.

Chang'an was captured by Wei during the previous year's summer attack, and the king of Yicheng had only been in business here for a few months. Although this person is good at fighting, the ministers of the Wei court are still worried, and they repeatedly ask the king of Wei to order troops to send troops to help.

When Tuoba Tao saw Song Shu, he immediately ordered the Wei army to prepare. At the same time, many people were dispatched to cut down Yin Mountain and prepare a large number of siege equipment.

If it is to rush to the aid of Chang'an, the Wei army is defending the city and does not need siege equipment. After Tuoba Tao gave the order, some courtiers began to be suspicious.

Sure enough, within a day, Tuoba Tao ordered again, ordering the general Heduoluo to lead 3,000 elite cavalry to drive ahead and go straight to the summer capital to unify Wancheng. Later, he ordered Situ Changsun Han and Changsun Daosheng to lead 30,000 cavalry and follow behind as the vanguard.

After the striker, there was the reinforcement of the Wei army.

Tuoba Su, the king of Changshan, led 30,000 troops, and then rushed to help, and Chang Shibudui, who had just returned to Pingcheng from the Song Kingdom, accompanied him.

As soon as the news came out, when the court was neutral, there were many courtiers who went up and down, directly stating the disadvantages of attacking the Xia capital Tongwan first, and at the same time persuading Tuoba Tao to send soldiers and horses to Guanzhong to relieve the crisis of Yicheng Wang Da Xijin first.

After listening to this, Tuoba Tao overrode public opinion and made a decision alone. If you don't go to Guanzhong, you will be close to Tongwan. If there is a person who does not comply, there is no need to deliberate, and punishment is given first.

A few days later, the forward troops and horses had just been drawn and the siege equipment had been built. Tuoba Fuzhen, the king of Nanyang, obeyed the king's orders left by Tuoba Tao and led 30,000 infantry to escort the equipment north.

At this point, Wei sent most of the soldiers and horses in the country, and 100,000 soldiers marched into the summer capital.

When Changsun Han and Changsun Daosheng led 30,000 cavalry to march, Tuoba Longyang had to go along. When he went to tell Sima to ask him, he directly refused.

The reason for the rejection lies in Langya.

I don't know when I will be able to return, Sima Wenzhi is worried that Langya will not stay in Anbei Wangfu with peace of mind, and will go to find him by himself, wanting to bring her with him.

The cavalry marched hundreds of miles a day. Even if Langya is good at running, Pingcheng is more than 10,000 miles away, and he can't bear to run for a few days.

If she had a horse alone, she would have avoided the fatigue of traveling, but it would not have been feasible for a wolf to ride a horse.

Therefore, Sima Wenzhi preferred to go with Tuoba Su's infantry.

Tuoba Longyang could not refuse, and Shangshu requested, and followed the infantry instead. Fortunately, Tuoba Tao only asked him to go with him, and he was not limited to which barracks he was in.

When the Wei advance was about to arrive at Junzijin, Sima Wenzhi was waiting for the infantry vehicle.

A few days before the opening, he had borrowed a book on the art of war from Tuoba Longyang, and took it out to read when he was bored with the army.

Sima Wenzhi is a descendant of the Jin royal family, if he had not been usurped by the Liu family back then, he would have been the emperor of the Jin State at this moment. Therefore, when he was raised, he was cultivated as a prince.

There are hundreds of schools of thought, Confucianism governs the country, and Legalism governs the people. In addition to Master Yu, there were also officials in charge of the laws and decrees of the Jin Kingdom to teach him.

Other than that, he dabbled in other sciences less. The vast majority have only heard of it, or have not even heard of it.

For example, military knowledge.

What he borrowed was the "Art of War" by Sun Changqing, the most holy soldier of the army. This book is strategic, and it is the treasure of marching and attacking.

The strategy was exhausted, and Sima Wenzhi felt tired after looking at it for a while.

The carriage and horses swayed, which made him feel a little dizzy, and he wanted to rest for a while. Before he could rest, there was the sound of footsteps outside the carriage, and then a man jumped into the carriage.

"Senior brother, what are you looking at? ”

It was Tuoba Longyang who came, jumped into the carriage and entered the carriage, and asked after seeing the book in his hand.

"Soldier's strategy. Sima Wenzhi spread out the homepage, signaling and responding.

"How did Senior Brother know that His Majesty would attack the Xia capital Tongwan first?" Tuoba Longyang saw it and asked the previous question again.

"I have already said why, and I will not repeat it. Moreover, judging from the current situation, it is also the best choice for him to do so. Besieged Wei to save Zhao, once Tongwan was attacked, the Xia Kingdom Plain Gong returned to help, and the siege of Chang'an was not saved and relieved. Sima Wenzhi had some knowledge of the Art of War, and when he responded again, he began to quote scriptures.

"What would happen if Helian Ding refused to accept the order and insisted on attacking Chang'an?" Tuoba Longyang thought for a while after hearing this, and asked again.

What he said was not groundless speculation.

There will be a foreign war, and some military orders will not be followed. If Helian Ding wanted to take Chang'an by heart, he would probably not pay attention to King Xia's order to return to the army.

Besides, Tongwan is strong, as long as the city gate is closed and cannot be held, when Chang'an is recovered, it will be too late for Helianding to send troops to rescue.

"Helian will definitely ask for it. Sima asked's answer unexpectedly, and without waiting for a reaction, he said again.

"The purpose of this dispatch is to unify 10,000 troops. If Helian Ding returned immediately after receiving the news, he was worried that he would be attacked on his back, so he could only retreat and return to Pingcheng. An army of 100,000 returned in vain. ”

"It makes sense, too. ”

Tuoba Longyang echoed after hearing this, and after echoing, he informed him of the matter.

"The master of the step camp is my uncle, and you also know him. I will recommend my brother in front of the two of you and participate in the strategy of the subsequent march on my behalf. ”

"The prince is thoughtful, if he has an idea, why don't he say it himself?"

"Alas. ”

Tuoba Longyang did not explain the reason, only let out a long sigh, and left after saluting.

Tuoba Longyang did not break his promise.

When it was getting dark, the people were given the order to set up camp on the spot and rest for a while. Sima Wenzhi had just jumped out of the carriage when a man approached him and ordered him to go to the main general's tent.

"Senior brother, let's stay first. ”

It wasn't long before he walked outside the tent of the Tuoba camp. I was just about to go in when I was stopped.

"What's the matter with King Anbei?"

It was Tuoba Longyang who stopped him, and he stopped and asked, with a suspicious look on his face.

"If you are asked about strategy, don't use 'he' to refer to Your Majesty in response. Tuoba Longyang opened his mouth to remind.

"Yes. Sima asked and turned to go in.

I don't know if he was told the latest, or if it was the farthest from the main general's tent, and when he entered, there were already many people inside. Most of them are military generals, and there are not many people like him who don't have military uniforms.

After a while, two or three more arrived. Seeing that the personnel were complete, Tuoba told the reason for summoning everyone to come.

"Since the afternoon of the day before yesterday, after His Majesty sent people to urge him, I have not seen any scouts come in two days. Now that the situation ahead is unknown, you can talk about what the generals have in mind. ”

As soon as Tuoba Su's voice fell, someone at the front of the queue responded.

His Majesty had already issued an imperial order before, ordering the infantry army to go directly to the outside of Tongwan City to station. The new order has not come, and although the front is unknown, everyone should continue to move forward according to the old order.

After hearing this, the rest of the generals echoed one after another.

Sima asked at the end of the queue, and shook his head slowly after hearing this. Although it was at the end, the shaking of the head was still seen by Tuoba Su.
