The loss of Tongguan led to the complete collapse of the entire Guanzhong defense line. Moreover, in terms of geographical location, Tongguan is the closest point to Chang'an among the fortresses of the Guanzhong defense line. The straight line distance is only more than 200 miles. After Deng Ai occupied Tongguan, he did not stop too much, so he rushed westward and rushed straight to Chang'an, intending to directly take Sima Zhao's nest.

When the news came, the whole of Guanzhong was in panic, everyone was in danger, and the situation was out of control in an instant.

Sima Lun received news of the loss of Tongguan a little faster than Chang'an. After all, it was only a few dozen miles from Pubanjin to Tongguan. Since Sima Liang transferred to Tongguan, Sima Lun was a little worried.

Because Sima Lun knew very well that Sima Liang was unable to be competent for the position of Tongguan Supervisor in terms of ability and experience. Sima Zhao put the defense system in Guanzhong in danger for his own selfish desires, which gave Sima Lun a headache.

It was already a turbulent time. In order to eliminate dissidents, Sima Zhao used all means to seize power, which undoubtedly made the situation in Guanzhong worse and unsustainable.

In fact, Hu Fen is not an ideal candidate for Sima Lun to guard Tongguan, but now that Sima's generals have withered, Sima Lun can only choose a general from a short man, barely let Hu Fen serve as the governor of Tongguan and be responsible for guarding the east gate of Guanzhong.

Sima Zhao was good. He thought Hu Fen was Sima Lun's man, so he simply gave up. He changed Sima Liang, who had no practical experience, went to the general Tongguan defense line. Sima Liang's opponent, Deng Ai, Ma Long and Qian Hong, who had been through many battles, would pick out one of them. Sima Liang could not be his opponent, so Sima Zhao's move undoubtedly pushed the Sima family into the fire pit. The Sima family and the throne that Sima Zhao had just usurped would also fall into the abyss that would never be restored.

However, even though the situation was critical, Sima Lun could not take the corresponding measures and could not advise Sima Zhao, because Sima Zhao's move to adjust defense this time was clearly targeted. If Sima Lun did not want to have a conflict with Sima Zhao, he could only choose to remain silent.

With internal and external troubles, Sima Lun could only choose to endure. He knew very well that once he had a conflict with Sima Zhao, it would only accelerate the defeat of the Sima family. Cao Liang was eager for them to fight in the nest, so Cao Liang was just taking advantage of the fisherman's benefits.

It’s a pity that Sima Lun’s tolerance and concession did not bring a good result. Shortly after Sima Liang took office, Tongguan was lost, and Sima Lun’s most worried thing still happened.

According to the news sent back, the loss of Tongguan is inseparable from Sima Liang's rash attack. It is precisely because Sima Liang was greedy for merit and made a rash move and was ambushed by Deng Ai, which led to the 20,000 Jin troops who attacked, together with Sima Liang himself, going but not returning. Tongguan's defense power was sharply reduced, and there was no backbone, so Tongguan's loss was completely reasonable.

This is the difference between having experience and inexperienced. Sima Liang has never participated in wars. Even if he has been familiar with military books since he was a child, he is at best a Zhao Kuo who talks about war on paper. He is simply incomparable to an old fox on the battlefield like Deng Ai. After being hit by Deng Ai's trick, it can only be said that Sima Liang's stupidity and cannot blame others.

Deng Ai's plan to lure the enemy for a day or two has not been done for a day. Although Hu Fen is not a famous general, he at least knows what to do and what not to do. Therefore, there is no problem with Hu Fen for several months to guard Tongguan.

But it was Sima Liang's turn. He had only been in office for a few days and lost Tongguan. He was also imprisoned and the entire Guanzhong was in a state of despair.

In terms of performance, Sima Liang ruined the Sima family and the great Jin Dynasty. In the reason, Sima Zhao was the real culprit. In fact, when Sima Zhao killed his brother, killing the emperor and usurping the power, the destruction of the Sima family had been laid. Today's situation was caused by Sima Zhao. The Sima family really reached the point of extinction of the clan, which was also the consequence of Sima Zhao's unscrupulous actions.

Sima Lun couldn't help but feel very regretful. If he hadn't been tolerating Sima Zhao and compromising and giving in, and when Sima Zhao had just become emperor, he would have clearly attacked him, the current situation would not have been like this.

In order to take the overall situation into consideration, Sima Lun had to tolerate Sima Zhao repeatedly, but what he got was Sima Zhao's indignation. At this moment, Tongguan was lost, Sima Lun realized that he was really too naive. He had to pay for his youth and naivety. The unrelenting compromise could not bring peace to the Sima family. Instead, it prompted the Sima family to perish faster. Although Sima Zhao had to bear most of the responsibility, Sima Lun was also to blame!

Zhong Hui was originally supervising the battle on the front line and fighting with the Wei army. However, when he heard the news of Tongguan's loss, Zhong Hui was also shocked and hurried back to Linjin Pass to discuss the plan with Sima Lun.

Because Zhong Hui knew very well that Tongguan's loss meant the collapse of the entire Guanzhong defense line. No matter how outstanding they played in Pubanjin, it would be useless. Now, it would be meaningless to stick to Pubanjin anymore. Zhong Hui asked Sima Lun to discuss the withdrawal of troops.

The current situation is indeed extremely severe. There is no smile on Sima Lun and Zhong Hui's faces. Sima Lun summoned all the generals to the central army's tent. The atmosphere in the tent was extremely depressing. Even the generals dared not breathe and listened carefully to Sima Lun's orders.

Sima Lun has no good idea now. The loss of Tongguan has made the Guanzhong defense line he made was useless. Moreover, the Wei army army led by Yang Hu was pestering him tightly. Even if Sima Lun wanted to escape unstoppably, it would not be easy.

Therefore, Sima Lun summoned all the generals to come, not to discuss the matter after evacuating Pubanjin, but to discuss how to withdraw troops safely.

In the current situation, the Jin army was entangled by the Wei army in Pubanjin. If the Jin army wants to escape from the battle, it will at least have to pay a considerable price. If it is followed by the Bingzhou army, it will be no easy task for all his 100,000 troops to escape from heaven.

What Sima Lun feared the most was the cavalry of the Wei army. The reason why he was able to restrain the Wei army's cavalry in Pubanjin was because in the Linjin Pass area, Sima Lun dug a large trench and cut off the mobile route of the cavalry, which made the Wei army's cavalry advantage unable to be exerted.

But once the Jin army evacuated Linjin Pass, they would no longer be able to stop the Wei army's cavalry. At the speed of the Wei army's cavalry, it would only take a moment to catch up with the fleeing Jin army.
