Ma Tan could still laugh on the battlefield at the moment, and when he arrived at the Han army camp, the smile shifted to other people's faces.

It turns out that smiles are conserved, and when you're not smiling, someone must be smiling for you.

On the same day, it was said that Zhuge Liang had cut off the newly made chicken feather Zen. Then, after the military affairs were almost dealt with that day, the new Luban lock was re-studied overnight.

When the Han army was full of smiles, Guo Huai also returned to Chang'an to report the results.

Although he didn't win much this time, Guo Huai was still admired by the generals of Guanzhong. At least Guo Huai was able to block the Han army for an hour and a half, and completed the task.

In the end, after Ma Jian came out of the horse, he was able to bring back the cavalry team in formation. This has been established, Guo Huai has a wealth of experience against the Shu army.

Regarding the results reported by Guo Huai, Sima Yi also expressed his approval.

Obviously, the range and lethality of the Thunderbolt are sufficient. Used to deal with the earthen walls built by Western Shu, Guo Huai's strategy was feasible.

In this case, Sima Yi also made a corresponding decision, letting Guo Huai and Sima Shi be fully responsible for countering the Shu army's wall-stacking strategy.

For a time, all the workshops and manpower in Chang'an were put into it, and the entire Chang'an began to build the Thunderbolt at full power. A large number of people cut down trees from Chang'an's outer counties, and then transported them to Chang'an by road, and then built them into thunderbolts.

At the same time, there was a little spare manpower, and Sima Yi also asked them to build stirrups and horseshoes on a large scale. All the Cao Wei cavalry in the entire Guanzhong began to iterate on their equipment, and practiced day and night under the leadership of Guo Huai.

On the entire Chang'an defense line, the Wei army camp began to operate at full strength, preparing to block the Shu army with all its might.

It should be said that Guo Huai's plan was a success. After the cavalry iterated equipment and continued drills, Guo Huai led the Wei army to launch many assaults on the Shu army.

Especially when Sima Shi cooperated with him as a feint, Guo Huai acted more quickly. A large number of thunderbolts were sent to the battlefield and advanced to 800 steps in front of the Han army's formation, wreaking havoc on the Shu army's earthen wall defense.

The Wei cavalry led by Guo Huai was also trained in constantly resisting the impact of the Han cavalry, trying to constantly improve their fighting style.

Under such a style of play, the Wei army won one after another on a long front. Section after section of the earthen wall was demolished, so that the Shu army had to redeploy the people to continue the construction.

Obviously, the Shu army built at a slower rate than the Wei army. Especially in the many battles in the back, Ma Jian never showed up, and it was difficult for Wu Yijufu and others to break Guo Huai head-on. As a result, Guo Huai was able to bring the Thunderbolt back to Chang'an intact even after destroying the earthen wall.

For a time, the Wei army won many victories, and its morale was greatly boosted, and many generals and soldiers began to have hope for holding Chang'an.

But such a seemingly positive cycle of continuous combat made Sima Yi's brows furrow deeper and deeper. Later, Sima Yishen began to mobilize manpower to prepare, and no longer went all out to build the thunderbolt.

As the first old fox of Cao Wei, Sima Yi's years of combat experience told him that there was something wrong with this.

In his opinion, although Guo Huai's style of play is disgusting, it is not impossible to counter. Ma Jian and Zhuge Liang are both extremely cunning people, how could they watch Guo Huai ride his face like this?

Especially Ma Yan, who was notoriously short-tempered, and as a result, he couldn't see anyone anymore.

And on the long front, all the offensives of the Shu army were stagnant. Except for Wei Yan in Lishan, who was still fighting with Sun Li for the gallop, all the other fronts were surprisingly quiet.

In the battle situation that seemed to be going well, Sima Yi was stunned to see the sense of urgency that the mountain rain was about to come and the wind was full of buildings!

"Something is wrong! Something is completely wrong! Ma Tan'er definitely has some conspiracy! What the hell am I missing? Sima Yi's brows furrowed, and his hair turned white several times while thinking day and night. But for now, he really can't think of any omissions.

At this moment, he, like the prime minister in history, is trying in every possible way to redeem the defeat in the face of the bloody collapse. But even if he was thoughtful in all aspects, there were still omissions that he didn't think of that would continue to bring the situation to its knees.

Feeling tired has become Sima Yi's biggest worry now.

The confrontation between the two sides continued for another two months, and the progress of the Wei army on all fronts was very smooth. But the ominous premonition in Sima Yi's heart became more and more obvious, and he had already begun to write to Sima Fu to say goodbye.

Goodbye brother, it won't be long before the two of us will be separated into two countries.

Finally, the Han army camp, which had been in confrontation with the Wei army for four months and had been silent for two months, suddenly made a move in January of the thirteenth year of Jianxing.

On the morning of this day, the Wei army post suddenly discovered that the main camp of the Shu army had abnormal movements. A large number of Han soldiers were digging the earth and tearing down the already solid earthen walls.

This action caused the Wei army to be unanimously excited, thinking that the Shu army was finally going to take the initiative to give up and withdraw.

But when the news reached Sima Yi, a flash of realization suddenly flashed in the eyes of the old artist.

"Something is wrong! The Shu army is opening the way for something! Sima Yi stood up suddenly, quickly put on his armor himself, and ordered urgently,

"Pass the order! From Juxian to Chang'an, all the troops have entered a state of combat readiness! All non-commissioned officers are fully armoured, and all officers must be on duty! ”

"Urgently inform the generals, all follow me to the city wall! I'm afraid the Shu army is going to have a showdown with us! ”

Seeing that the always steady Metropolitan Governor suddenly exploded with his tail being stepped on, everyone looked at each other. The generals who knew Sima Yi well were even more nervous, and they realized that the matter seemed to be big.

Under Sima Yi's urgent military order, all the Wei troops in the vicinity of Chang'an were put on high alert. All the non-commissioned officers lined up in armor, and the officers were patrolling at their posts, and everyone's nerves collapsed again.

However, in their opinion, perhaps the Shu army is about to launch a final battle before withdrawing. Therefore, although the Wei army felt that a vicious battle was coming at the moment, it was not a big problem.

Soon, Sima Yi arrived at the head of Chang'an with his guards and generals. In this place, Sima Yi could see the movements of the Han army very clearly.

In his sight, a large number of soldiers were stubborn and stubborn, and they wantonly cleared the land and opened the way. Even though the gap has been opened wide, the Han army is still expanding outward.

"Is it finally coming?" Sima Yi's palms were already covered with sweat, and he stared closely at the movements of the Han army.

Finally, the Han army cleared out the nearly ten meters of earthen wall blocking the front of the main camp. After the gap was large enough, the Han army slowly dragged out the big killing weapon that had been covering for two months with the requisitioned oxen from the place where it could not be seen.

That's right, cows!

And when the big killer revealed his true face, Sima Yi's eyes suddenly glared like a copper bell, and his face changed in a flash.

"What the hell!!"
