Xiahou Nan and Xiahou Xuan both surrendered to Wang Ping and surrendered to the Han Dynasty, which caused Wang Ping to suddenly add 30,000 new surrendered troops.

After withdrawing his troops from the Meridian Valley, Wang Ping also joined Wei Yan's troops by the way.

If Xiahou Nan's troops are on the verge of running out of food, then Wei Yan's troops are really out of food.

Xiahou Nan's troops still had horses to kill, while Wei Yan's troops were all infantry, and there were no horses to kill, although they only ate one meal a day in the later period, but they had no food to eat.

When Wang Ping's troops connected with Wei Yan's troops, Wei Yan's troops were already hungry and almost fainted, and Wang Ping hurriedly asked people to send food up, so that Wei Yan's troops could be supplied.

After Wei Yan's troops left the Meridian Valley, Wei Yan personally visited Wang Ping to express his gratitude! For the Northern Expedition, Wei Yan really endured all the hardships of the world along the way.

First, he led his troops to leave Yong'an, crossed the mountains and mountains to reach Hanzhong, and suffered from hunger all the way. Later, he fell into a dilemma in the Meridian Valley, and once again starved without food.

Although Wei Yan is very tenacious, the hero can't stand being hungry, it's nothing to be hungry for a day or two, but when he was trapped in the Meridian Valley, Wei Yan felt that the days of starvation seemed to be endless.

Several times, Wei Yan wanted to lead his troops back to Hanzhong, but when he returned to Hanzhong, where should this old face go? Not to mention that he may be impeached if he leaves his post without permission. Even if everyone vouched for him and exempted him from responsibility, but he tossed and tossed in vain, wouldn't his reputation be ruined.

Therefore, Wei Yan would rather die in the Meridian Valley than retreat to Hanzhong and be laughed at.

Unexpectedly, he found that the Wei army began to withdraw from the Meridian Valley in an orderly manner, and he began to send troops to pursue, but who expected that the Wei army shouted one after another that they had returned to the Han Dynasty, and everyone was now a Han army, and their own people did not fight their own people!

At first, Wei Yan didn't believe that Xiahou Nan and Xiahou Xuan would surrender to the Han, thinking that this was just a delaying tactic, but when the generals under Wang Ping came to meet Wei Yan in person, Wei Yan knew that Xiahou Nan, Xiahou Xuan and the 30,000 Wei army had really surrendered to the Han.

Wei Yan suddenly had a feeling of wanting to cry without tears, feeling that he had worked hard to fight the Wei army in the Meridian Valley, and in the end, all the fruits of victory were won by Wang Ping.

However, Wei Yan couldn't say anything about Wang Ping, because Wang Ping had a life-saving grace for him. Wei Yan could only secretly lament in his heart, all this is fate!

Now Wang Ping has an army of 50,000, but he only has 10,000, and he will definitely come to the Northern Expedition to make meritorious contributions, and he will suffer a great loss.

After seeing Wang Ping, Wei Yan respectfully bowed his hand and said: "Thank you for saving your sons, if you don't have children, I'm afraid I'll be trapped and die in this meridian valley!" ”

Wang Ping hurriedly smiled: "What did Wen Chang say?" You and I are comrades, mutual rescue was originally due duty, originally Jiang Weidu was going to come in person, but Chang'an has a Wei army pressing the border, so Jiang Weidu sent me to the rescue. ”

Hearing that Chang'an City was about to lead to a big battle, Wei Yan was suddenly a little excited, and hurriedly asked:

"Zijun just said that the Wei army is coming to attack Chang'an, so there is still a battle to be fought in Chang'an?"

Wang Ping said with a smile: "Cao Wei has not been destroyed, why should Wen Chang worry about having no battle to fight?" Now that Wen Chang has arrived in Yongzhou, he might as well stay and fight with Jiang Weidudu! ”

It stands to reason that Wang Ping and Wei Yan are both governors of one side, and their status is almost the same as Jiang Wei, but Wei Yan saw that Wang Ping handed over the military power very calmly, and he naturally didn't say anything, and this command power could not win against Jiang Wei no matter what.

Besides, Jiang Wei saved Wei Yan's life from Ma Dai's knife, and Wei Yan was very grateful to Jiang Wei in his heart. Now Jiang Wei only took two years to take all the two major states of Yongliang, and achieved the feats that Zhuge Liang had failed to achieve in his life, Wei Yan admired Jiang Wei from the bottom of his heart.

Therefore, Wei Yan made up his mind that he would no longer fight for any military power, as long as he could do his part in the Northern Expedition, he would have no regrets in this life.

So Wei Yan said with a smile: "Of course Wei is willing to stay in Yongzhou to fight and wait for the command of Governor Jiang Wei, I don't know if Governor Jiang Wei has given me any military tasks?" ”

Wang Ping spread out the map and said to Wei Yan: "Of course there is, when I led the army out of Chang'an, Governor Jiang Wei had an explanation, and my first priority was to rescue General Wei Yan, you, and eliminate or capture Xiahou Xuan and Xiahou Nan's troops. Once this is done, you will need to lead your army into this area. ”

Wang Ping pointed to a location on the map, which had already been drawn with a red circle, Wei Yan fixed his eyes and saw that the place circled by the red circle was located in the southeast of Chang'an City, and there were two words written on it: Lantian.

Wei Yan was a little curious, Lantian is close to Huangni Pass, Huangni Pass is the only way to Shangyong in the Guanzhong Plain, and it has been guarded by Wei troops for many years, I don't know why Jiang Wei asked Wang Ping to send troops here.

Wang Ping explained: "It seems that General Wei Yan is a little puzzled, does he think that it is too risky for our army to go to Lantian, Lantian is Tongguan to the north, Huangni Pass to the south, and Huangniguan is Wuguan to the east, this is Cao Wei's dangerous enemy, there must be a heavy garrison, and entering Lantian will fall into passivity, right?" ”

Wei Yan nodded in agreement.

Wang Ping said with a smile: "General, don't worry, Huangniguan is already under the control of our Han army, but the Wuguan has not yet been opened, Jiang Weidu sent me and others to enter Lantian, naturally Lantian has been controlled by our army." The next target of our army after entering Lantian was Tongguan. ”

"Are we going to fight Tongguan? Didn't it mean that Cao Wei had a large army attacking Chang'an, wasn't Cao Wei's army stationed in Tongguan? ”

Wang Ping shook his head and said, "According to the latest news I received, Cao Wei sent an army of 120,000 to attack Chang'an, but the camp of the Wei army was not located in Tongguan, but twenty miles east of Chang'an City. ”

Wei Yan roughly estimated the location mentioned by Wang Ping on the map, and felt that if this was the case, then the camp of the Wei army's 120,000 troops should be between Chang'an and Tongguan, and it was extremely close to Chang'an, and it was quite far from Tongguan.

Wei Yan, who had been on the battlefield for a long time, immediately captured a once-in-a-lifetime fighter: as long as the 60,000 troops of Wang Ping and Wei Yan allied forces bypassed the base camp of the Wei army and raided Tongguan in the northeast, then as long as the surprise attack was successful and Tongguan was controlled, Cao Wei's 120,000 troops would not only be cut off from the supply line, but also be surrounded by the Shu army and completely besieged between Chang'an and Tongguan.

Wei Yan suddenly asked overjoyed, "Who is the commander of this Wei army?" I'm afraid you're not a fool, are you? How can such a big hole be left for us? Isn't that self-defeating? ”

Wang Ping said with a smile: "The commander of the Wei army is Cao Shuang, the general of Cao Wei's Wuwei, and he is indeed a man with great ambitions and talents, but Jiang Weidu Du has used arrogant tactics against him, I am afraid that at this time, Cao Shuang has already been proud of his tail to the sky!" ”

Wei Yan couldn't help but laugh and said, "That's very good!" That's great! If you and I succeed in a surprise attack on Tongguan, then our army has 60,000 troops in Tongguan, and Jiang Weidu has 80,000 troops in Chang'an, adding up to 140,000 troops, 140,000 around 120,000, why worry that this battle can't be won? ”

Wang Ping said with a smile: "It's 170,000 to 120,000, and Governor Jiang Wei also urgently dispatched another 30,000 reinforcements from Yongliang counties, and they will arrive in Chang'an soon, so the top priority is to rush to Lantian quickly, and then prepare for a surprise attack on Tongguan." ”
