Liu Yin was quite confident and calm when he said this, because he was the only person in the world who had walked this road. In his previous life, Liu Yin participated in an event to commemorate the 75th anniversary of the victory of the Long March, and this commemorative activity has a name, called "Remembering the martyrs, re-walking the Long March road", and felt the greatness of the Long March in a personal way. Of course, the 25,000-mile journey was not traveled one by one, and Liu Yin's unit chose the most difficult section of the journey to climb the snow-capped mountains and cross the grassland, starting from Luding on the Dadu River and ending at Lazikou in Gannan.

The most difficult part of this section of the road is to continuously climb over five snow-capped mountains with an altitude of more than 4,000 meters, such as Jiajin Mountain, Mengbi Mountain, Yaxia Mountain, Changde Mountain, and Dagu Mountain, and cross hundreds of miles of grassland where no one is inhabited, birds and beasts are rarely visited.

However, frankly speaking, Liu Yin did not think that this section of the road was so difficult to walk, and the reason why the Red Army suffered heavy casualties when climbing the snowy mountains and crossing the grassland was because of insufficient preparation, lack of food and clothing, and lack of medicine, and the Red Army officers and men either starved to death or froze to death.

The move of the capital to Nanzhong, Liu Yin germinated the idea of detouring to Longxi, the main force of Wei went south, and the entire Guanlong area was empty, if you want to select the counterattack target, the Guanlong area is undoubtedly the best. What's more, this road is something that no one would ever think of, Zhong Hui only thought that by occupying the Sword Pavilion, and even including the Yinping Bridge, the road from Yizhou to Guanlong could be completely blocked, and the land of Guanlong would be safe and sound, and there would be no need to take any precautions.

In this case, attacking Longxi in a roundabout way can achieve the effect of taking it by surprise and attacking it unprepared. The importance of Guanlong's geographical location is self-evident, and Zhuge Liang's goal in his life is to take Guanlong and open the door to the Central Plains. For Liu Yin, this is an opportunity for a Jedi counterattack, taking advantage of the time when Wei and Wu are in a stalemate and flawless clone. won Guanlong in one fell swoop and counterattacked the general trend of the world.

The key to success or failure is to get out of this unprecedented road.

Is this road difficult? Of course it's hard to walk! But it is not that you must not go, as long as you are fully prepared and properly arranged, Liu Yin's grasp of walking out of the snowy mountains and meadows is still relatively large, after all, this road has been walked by himself once, and Liu Yin still has a deep impression of the snowy mountains and meadows. It couldn't have been more fitting for him to be the guide.

As for whether the ancient and modern landforms are the same, Liu Yin is not too worried, after all, time has only been pushed forward by 1,800 years, and it is far from the vicissitudes of life. At most, the swamp area is a little larger and a little more muddy. The roads that Liu Yin once walked will not disappear completely, and many landmark mountains and rivers are still fresh in Liu Yin's memory.

As early as last month, Liu Yin had arranged for Chen Shou to go to Hanjia County, and the main purpose was to raise grain and grass. Hanjia County is adjacent to Shu County. However, the territory of Hanjia County is steep and steep, the land is dangerous and the mountains are high, and the two countries of Wei and Wu have not yet tore each other apart in Chengdu, how can they have extra troops to invade Hanjia County, so Liu Yin chose the advance base here. It's still more reasonable.

Of course, Chen Shou didn't know, he would never have thought that Liu Yin had already made a plan to cross the snow-capped mountains to the west, and Chen Shou also thought that Liu Yin was going to raise grain and grass in his Hanjia for the purpose of counterattacking Chengdu.

Now that he has obtained the exact information about Guan Long, it also reassures Liu Yin, after all, before this information, the enemy situation of Guan Long is just a judgment of Liu Yin, and if you really want to put the plan into action, it is far from enough to rely on imagination.

And now that Liu Yin has taken the first-hand information, the plan to enter Longxi has also officially carried out a substantive stage.

In the face of Deng Ai's stunned, Liu Yin smiled secretly, if even Deng Ai, who was the most good at making strange mistakes, couldn't believe it, Liu Yin was confident that he could completely hide from the world, when he led a strange army to appear on the land of Longxi, it is estimated that everyone in the world will be stunned in surprise.

The reason why Liu Yin was the first to communicate with Deng Ai is because of this march into Longxi, Deng Ai is not one of the most critical figures, Deng Ai has been in Longxi for many years, and his protégés are all over Yongliang, as long as Deng Ai raises his arms in Longxi, he must be a cloud of responders, and he can surrender without a fight, which is the best way to use troops, and it is precisely because Liu Yin has a lot of reliance on Deng Ai in Longxi that he was the first to communicate with Deng Ai.

Of course, Liu Yin also included this plan in the top secret level, and the people who know about this plan will never exceed a single digit, and it is a person he absolutely believes, Liu Yin knows that Wei State's espionage activities are rampant, once this plan is leaked, it is Wei State that is prepared, not only will it be wasted, but it is likely that the whole army will be destroyed.

However, Deng Ai and Liu Yin are extremely relieved, Deng Ai was originally a Wei general, and he was poor, and he could no longer meet Cao Wei, and Zhong Hui, the commander of the Wei army, was an undying enemy, and he told Deng Ai the plan, but there was nothing to worry about.

Liu Yin told his plan and discernment, Deng Ai heard it, or shook his head or nodded, only in the end, he was drunk, he was also deeply shocked by Liu Yin's bold and arrogant plan, if Liu Yin's plan succeeded, it would be a feat that no one had ever done before, and Han Xin's secret crossing Chen Cang was simply weak compared to it.

Deng Ai also had to admit that Liu Yin's plan was detailed and perfect, although it seemed crazy, but the plan was thorough and rigorous, interlocking, and it was impossible to find its flaws.

"It's really terrifying!" Deng Ai couldn't help but sigh secretly in his heart, and at the same time had a more brand-new understanding of Liu Yin, Deng Ai's use of troops was very strange and dangerous, and Liu Yin was obviously better than him, which made Deng Ai couldn't help but admire, and felt more reverence from the bottom of his heart.

"Mr. Ai, this plan is very confidential, God knows, you know and I know, and it must not be known to a third party." Liu Yin finished admonishing.

Deng Ai is such a smart person, even if Liu Yin doesn't remind him, how can he not know, but the possibility of leaking secrets on Deng Ai's side is extremely small, Deng Zhong has been transferred to serve in the army and became the commander of Liu Yin's private soldiers, and Deng Ai has no one around him except for private guards.

After Liu Yin and Deng Ai talked in detail, he learned from each other's strengths and weaknesses, or got a lot of valuable opinions, he went back and sorted it out overnight, and after the fifth watch, he went straight to the palace, wanting to see Liu Chan. (To be continued......)
