Sima Yi, who was hidden in the rear army, only felt a chill in his back and a dry throat when he saw the "Sima Yi" on the horse turned into a dead ant, but he forcibly endured the shock and anger in his heart, and just signaled with his eyes that Yang Ren and Yang Anger would continue to organize the troops to quickly pass through the valley, without even revealing the slightest abnormality.

Since the last time Sima Fang was plotted in Yizhou's lair, Sima Yi secretly looked for people who were similar to his body and appearance, and then found a way to either recruit or kidnap them, and since then he has been his own stand-in, distracting the enemy's attention in the open when there are many people in danger.

The fake "Sima Yi" riding on a horse is one of the several stand-ins he secretly raised. This time he went north just in case, Sima Yi brought a total of two stand-ins in the army, and now one was shot dead by Cao Xing, and the other was still kept in the dark, not knowing that he was a stand-in This bowl of "technical rice", if one is not good, he will take his life in.

The place where Cao Xuan was hiding was that several members of the Shadow Team used ropes to hang Cao Xuan down, and then took the rope and left. Therefore, even if the Yizhou army in the valley was suspicious of Cao Xing's hiding place, because of his haste, it was too late to send someone to take out a rope to hang people down to check, not to mention that Sima Yi's order in secret was to quickly pass through the Tiger Shooting Valley.

At the beginning, Sima Yi was suspicious of such an excellent place to set up an ambush in Tiger Valley, why the vanguard army stationed in Yixian County would not send people to stop it, but now when he saw that the mysterious killer quietly took the name of the promotion, he suddenly felt that the troops defending Yixian County were really empty, so he came up with such a way to deal with him.

Sima Yi's suspicions were justified, but he didn't expect that this Cao Xing's attack was completely outside Jia Xu's plan. Up to now, except for a few shadow team members who were with Cao Xing, the rest of them didn't know that Cao Xuan was still alive.

As the saying goes: a wise man thinks a thousand times, and he must make a mistake. Jia Xu was only concerned about leading the army to evacuate at that time, but he forgot to deliberately leave some men near the Shooting Tiger Valley to dispel Sima Yi's suspicions. If Sima Yi passed through the Shooting Tiger Valley safely, he would feel that he had arrived in Yixian County so smoothly, then there might be some ambush in Yixian County, or Jia Xu would have a backhand.

Once Sima Yi became suspicious, he would then have suspicions about the 5,000 vanguard soldiers stationed in Yixian County who fled without a fight, and then Jia Xu's plan to blow up Yixian County would have to encounter problems.

Now, Cao Xing's unintentional "troublemaking" just catered to Sima Yi's suspicions, and also fulfilled Jia Xu's plan, the 30,000 Yizhou army did not care about searching for the assassins hidden in the Tiger Shooting Valley, but quickly gathered into one after passing through the Tiger Shooting Valley, and then quickly headed towards Yixian.

Late at night on the day when the Yizhou army left, several shadow team members lurking in the distance hurriedly rushed to Cao Xing's hiding place, put down the rope and hung Cao Xing, who had been lurking for three days, to the top of the valley.

One of the team members asked in a low voice, "General Cao, have you succeeded?"

Cao Xuan replied with some confusion: "If the man on horseback is indeed Sima Yi, I believe I did shoot through his throat." It's just that I secretly observed through the 'clairvoyance' and found that the Yizhou Army did not panic due to the loss of the commander, so I suspect that the person who was shot to death is not the real Sima Yi!"

Another member of the team added: "When we were in the dark room, we specially showed you Sima Yi's sketch, although the distance is far away, you can still distinguish it, right?"

Cao Xuan said with great certainty: "The person on the horse is indeed very similar to the portrait in the sketch, but this does not mean that it is Sima Yi." Let's hurry to Yixian and remind the defenders there that it's better to pay attention to this matter!"

So a few people packed up and hurried in the direction of Yixian County at night.

When Sima Yi led his army to Yixian, it was already night, and it began to rain in the sky. He ordered his troops to camp on the spot, and the army would attack the city at noon tomorrow.

That night, a force rushed out of Yixian County with the intention of attacking the camp, but was repulsed by the Yizhou army, which had been prepared for a long time, and Sima Yi was even more convinced that the troops defending Yixian were limited.

At noon on the second day, the rain was getting heavier and heavier, but Sima Yi's face showed a cold smile. He calmly ordered: "The vine armor soldiers are attacking the city!"

This time, Sima Yi learned the previous lesson, and used the most effective means as soon as he came up, preparing to conquer Yixian in one fell swoop.

When the five thousand rattan armor soldiers of the first ** city climbed to the head of Yixian County, they were a little surprised to find that there was no trace of the defenders in the city, leaving only a silent and empty city.

The news that the defenders of Yixian County were missing quickly spread to Sima Yi, Sima Yi thought for a moment, and then said to Hu Lie and Tian Xu beside him very confidently: "In this way, Jia Xu has nothing to do, and can only use these little tricks to confuse and delay the actions of our army! I am sure that the retreating vanguard soldiers must have gone to the Xianqin area near Gaoping in the northeast, and Jia Xu is exchanging the city for time. ”

Hu Lie and Tian Xu nodded yes one after another, praising Sima Dudu's clever calculation.

Looking at the gate of Yixian County, which was quietly opened in the rain, Sima Yi ordered the troops to wait in place, and first let a force that was proficient in organs and secret passages enter Yixian County and carefully inspect the entire city.

After two hours had passed, the troops who had entered the city came back to report that no anomalies had been found in the city, and that there were occasionally some secret chambers, which were also empty and did not hide any enemies. Sima Yi then ordered his troops to enter the city to rest, and it was almost evening.

After entering the city, Sima Yi still insisted on living in an inconspicuous ordinary courtyard, and let the second stand-in live in the Hanyang County Shoufu (that is, Guoyuan's mansion).

In the middle of the night, even Sima Yi himself was already asleep. In a certain tunnel half a mile away from Yixian County, several ghostly figures suddenly appeared, and after they lit a thick black rope, they walked away into the distance without looking back.

In order to ensure that the rope would not be extinguished when it burned, Jia Xu used an engineering team to dig hard underground for more than ten days. The tunnel was several feet underground, and the air stored in it was enough for the fire rope to burn, which was personally tested by the engineering team members at that time.

Then in the night, Cao Xing finally approached Yixian County, looking at the direction of the dark city in the distance, he was about to ask the team members around him how to connect with the shadow team members in the city, at this time, a scene that he would never forget happened.

Cao Xuan first saw a sudden fire in the direction of Yixian County, almost like a huge firework, and then he felt the ground under his feet shake violently, and finally heard a dull sound in his ears.

Cao Xuan wiped the sweat from his forehead, and then asked the team members around him in a low voice: "Did there be a big explosion in Yixian County? How much gunpowder does this consume?"

A team member who is proficient in the use of gunpowder replied softly: "A lot, a lot, enough for our Liangzhou legion to use gunpowder for many years!"
