If Sima Lun wants to take revenge, others are not reliable. The only thing he can count on is Jiang Wei, who is determined to fight the Northern Expedition. Therefore, Sima Lun must fully support Jiang Wei.

Fortunately, Sima Lun had an army in his hands, which gave him an important position in Shu Kingdom. If Sima Lun surrendered to Shu Kingdom alone like Xiahou Ba, he would definitely not be valued at all, and would not be the target of various factions in Shu Kingdom's scrambling to win over.

Even the later ruler Liu Chan favored Sima Lun and betrothed Princess Nanping to Sima Lun, which shows that Sima Lun's status is extraordinary.

However, Sima Lun was still the family's great cause of revenge. The result of the two battles in Longxi made Sima Lun realize a reality, that is, it was almost a luxury to march from the Guanlong area. The Shu army had already experienced countless failures in this direction, and the chance of success was slim.

Fortunately, Jiang Wei also realized this. After the Second Battle of Longxi, Jiang Wei returned to Beijing under the imperial edict and never returned to Hanzhong. Instead, he turned to Yong'an and tried to find a new breakthrough from the east road.

Sima Lun also agreed with Jiang Wei's transformation. For a long time, the Northern Expedition of Shu has been very single, which is to go out of Guanlong Yongliang. Except for the first Northern Expedition that caught Wei off guard, many other attacks were prevented by Wei, so it was hard to do anything.

The Yongliang defense line of Wei State has always been built by Sima Yi. Even though Sima Yi was later transferred back to Luoyang, the core tactics of the Yongliang defense line have never changed. In other words, Sima Yi supported the overall situation of the Yongliang defense line, and the Shu army has never been able to break through this line of defense for decades.

As Sima Yi's youngest son, Sima Lun is still very familiar with everything about the Sima family. Although the Yongliang defense line has changed hands now, the Wei army's defense ability has not decreased accordingly, but has increased. The two battles in Longxi prove this. It is very difficult for Jiang Wei to seek a breakthrough from the Guanlong area.

Therefore, changing the direction of the offensive and finding new breakthroughs became an urgent problem that Shu Kingdom’s Northern Expedition needed to be solved.

In fact, there is another way for the northern expedition of Shu Kingdom, which is to go east along the Han River from Hanzhong and take the three counties of Shangyong directly.

When Jiang Wan was in power, he once vigorously promoted this Northern Expedition route. For this reason, Jiang Wan also visited Hanzhong to supervise the construction of warships and prepare to attack Shangyong on both sides of water and land.

However, this plan was opposed by the ministers in Shu. The terrain of Hanzhong was higher than that of Shangyong. There was no problem with the Shu army sending troops. It was high-level and unstoppable. However, it was easy to go and difficult to come back. Once the attack was frustrated, it was not so easy to retreat to Hanzhong, and it was likely to be destroyed by the entire army.

From this point of view, the risk of attacking Shangyong is too great. It is not like advancing from Guanlong. It can attack and retreat or defend. Once the attack fails, the consequences will not be affordable by Shu.

Therefore, Jiang Wan's ambitious plan eventually aborted due to opposition from his ministers, and Jiang Wan eventually died of illness and depression. The plan to attack Shangyong was put on hold since then and no one mentioned it again.

In fact, from Zhuge Liang's persistence in going to Qishan to attack Wei, we can see that Zhuge Liang did not support the attack on Shangyong. The reason is actually very simple. Shu Kingdom has few soldiers and dare not take too many risks. Once he encounters a fatal blow, the meager family background of Shu Kingdom will soon be over. With Zhuge Liang's prudence, of course, he will not make such a mistake.

Therefore, Zhuge Liang had no intention of advancing from Shangyong throughout his life.

After Jiang Wei took over Zhuge Liang's unfinished career, he still always regarded Guanlong as a breakthrough for the Northern Expedition. He fought repeatedly and was persistent and had no regrets.

However, after experiencing the failure of the last two northern expeditions, especially when Sima Lun surrendered and Shu Kingdom had already taken over the five counties in Longxi, he still could not resist the crazy counterattack of the Wei army. This really made Jiang Wei feel sad. It was not that he was not doing his best, but that the enemy was too powerful and powerful to the point where Shu Kingdom could no longer match.

If the Guanlong road is not clear, Jiang Wei can only take another path. Shangyong is basically not within Jiang Wei's consideration, and there is no other offensive route at all. Of course, Jiang Wei will be deeply troubled by this.

But at this moment, a turning point quietly appeared. Cao Liang launched a large army to attack Wu, which was very intended to annex the Wu Kingdom. Jiang Wei immediately realized that his opportunity had come, so he changed the defense zone with Yan Yu and transferred the right general Yan Yu to Hanzhong, while Jiang Wei led his troops to Yong'an.

Yong'an is an important town on the eastern front of Shu, but it is not adjacent to Wei, but to Wu. Since Zhuge Liang reconstructed the relationship between Shu and Wu, Yong'an has never experienced war again. The peace between Shu and Wu has been maintained for nearly forty years.

Since Yong'an and Wu were neighbors, it was naturally impossible to become the base for the Northern Expedition of Cao Wei. However, the situation in the Wei State's attack on Wu changed drastically, and Jiang Wei had an extremely sensitive sense of smell, so he moved the strategy of Shu's Kingdom eastward and planned to advance from Yong'an eastward and seize Jingzhou.

Sima Lun strongly agreed with Jiang Wei's move. After the road to Guanlong was blocked, Yong'an became Sima Lun's last hope. If he could find a breakthrough from Yong'an, the great cause of revenge would not become an empty talk again.

The situation of Wu can be described as a thousand miles a day. Jianye was captured by the Wei army and Wu also officially declared its demise. Although there were still remnants of the Wu army resisting in Yangzhou and Jingzhou, the situation of Wu was already overwhelmed and it was defeated.

The defeat of Wu undoubtedly gave Jiang Wei a huge opportunity. Lu Kang surrendered, causing Jingzhou to unexpectedly return to Shu, and the Shu court was also full of joy.

Sima Lun also realized that this was his best and last chance to revenge. He could not miss it, and he would never miss it. At that time, the latter leader Liu Chan was both happy and worried. He was happy that the territory of Jingzhou finally returned to Shu Han. He was worried that he had no soldiers to adjust. Sima Lun immediately took the initiative to step up and lead his troops to reinforce Jiang Wei.

After arriving in Xiling, Sima Lun was also valued by Jiang Wei and arranged for him to be responsible for the most important defense line of the pavilion.

Sima Lun's performance at the Qiting Pavilion was naturally extremely eye-catching. He successfully blocked the Wei army's attack and steadily defended the Qiting Pavilion, leaving the Wei army unable to advance.

The success of the Battle of Qianting undoubtedly greatly boosted the morale of the Shu army. Just when everyone believed that Xiling could be defended, bad news came from Xiling - Xiling was lost!

This was the heaviest blow to Simalun. Simalun understood that once Xiling was lost, his dream of revenge would be completely shattered.
