Chang'an has also been paying attention to the dynamics of Wuguan, Wuguan is tight, and Liu Chen and others are also worried.

Although Wuguan took the lead in igniting the flames of war, the other two armies of the Jin army were also rushing towards Tongguan and Pubanjin, and the battle was about to break out, and the situation was also urgent.

Wang Ji's urgent document was placed on Liu Chen's case, and Liu Chen urgently summoned Yongzhou Assassin Shi Yizheng and the right protector to discuss the plan.

Yin Zheng said: "Wuguan is the throat of the southeast of Guanzhong, there is no room for loss, Wang Ji with 10,000 people to resist Du Pre 50,000 troops, it is indeed a little tight, the lower officials think that they should immediately send reinforcements, and it will change later." ”

Liu Chen looked at Lian Hong and said, "I don't know what General Jian thinks?" ”

Chang'an's current reserve only has the right army of Zhan Hong, and the right army only has two battalions and 10,000 horses, and now the three major key passes are all in an emergency, so such a small number of troops is quite a drop in the bucket.

Xian Hong said with a worried face: "The Jin army is coming in three ways, the entire eastern front is tight, and now the fierce battle in Wuguan is in full swing, and it is not surprising that the troops are tight, but the terrain of Wuguan is dangerous, easy to defend and difficult to attack, and it is not easy for Du to take Wuguan." The last general's concern is Pubanjin in the northeast of Guanzhong, and General Huang defends the Yellow River with 10,000 troops dozens of miles long, which may be difficult to deal with. If all the right army is transferred to Wuguan, if Kasakatsu is tight later, I am afraid that there will be no soldiers to save it. ”

Liu Chen was a little worried, unlike Tongguan Wuguan, which has the danger of mountains and rivers, the only thing Pubanjin can rely on is the danger of the Yellow River, but the defense line of the Yellow River that is dozens of miles long, if the troops are divided, Huang Chong's troops will be much weaker, and if the Jin army adopts multiple ways to force crossing, Huang Chong will definitely be overstretched and difficult to deal with. Wuguan needs to send troops to rescue, but Pubanjin is even more urgent, Liu Chen really has the feeling that it is difficult for a good woman to cook without rice, it would be good if Liu Yin was there, but unfortunately now Liu Yin is fighting in Liangzhou, although the urgent documents have been sent, but when to return to the army is unknown.

It is difficult to quench the thirst of the distant water, Liu Yin's reinforcements can not be counted on for the time being, Liu Chen and Yin Zheng, Zhan Hong discussed, decided to divide the right army into two, Jincheng battalion went to Wuguan to rescue, and Zhan Hong personally led the Longxi battalion to reinforce Pubanjin, so distributed, both ends were taken care of.

Hiroshi immediately took the order and left.

Yin Zheng said: "Your Highness divides the troops like this, it is not inappropriate, but the Jin army is 200,000 attacking, 50,000 people attacking Wuguan, 50,000 people attacking Pubanjin, 100,000 people attacking Tongguan, and General Fu only has 15,000 people guarding Tongguan, how can he resist Yanghu's 100,000 army?" ”

Liu Chen was silent, he now has no soldiers in his hands to adjust, Tongguan can no longer send reinforcements, and the only thing he can hope for now is that Fu He can resist.

"General Fu, now the safety of the entire Guanzhong falls on you." Liu Chen silently looked at the east and said secretly in his heart.

After Hu Fen arrived at Pubanjin, it was just in time for the spring flood season of the Yellow River.

Pubanjin is the most important ferry port on the Yellow River, and it is the main point of traffic from Qin to Jin. Pubanjin is a popular saying, referring to the entire Yellow River ferry, in fact, subdivided, on the east bank of the Yellow River called Pujin Pass, on the west bank of the Yellow River called Linjin Pass, these two passes are ancient place names, from the Spring and Autumn Period and the Warring States Period has been used to the present, it has been some years, when the Qin and Jin Dynasty confronted each other across the river, Pubanjin is the frontier of both sides.

After the Shu army entered the Linjin Pass, the Wei army also sent troops to garrison the Pujin Pass to resist the enemy, because of the Yellow River, the two sides have never clashed, and there is no incident.

However, after Sima Yan decided to counterattack the attack, he sent Hu Fen to lead his troops to Pujin Pass, and for a time the battle clouds were dense over Pubanjin, and a big battle was about to break out.

In order to prepare for the battle of crossing the river, after Hu Fen arrived at Pujin Pass, he immediately began to mobilize ships. Since the Jin army did not have a formed naval army on the Yellow River, in order to cross the river, Hu Fen had to requisition some civilian merchant ships and fishing boats, and the lack of warships was the top problem in front of the Jin army.

During the period of Wei-Wu confrontation, in order to maintain the confrontation with Wu, Wei also built a large number of warships in Jingzhou and Huainan, although the overall strength of Wei's naval army was inferior to that of Eastern Wu's, but if these warships were transferred to the Yellow River, it would be a severe test for the Shu army defenders on the other side of Pubanjin.

After all, a warship is a warship, and it is by no means comparable to those civilian merchant ships and fishing ships, whether it is from the displacement to the sturdiness of the ship, it is by no means an order of magnitude.

However, the Yangtze River water system, the Huai River water system and the Yellow River water system were not connected, and there was no Beijing-Hangzhou Grand Canal in those days. A detour was suggested, but the distance was too far and the sea was unpredictable, and eventually Sima Yan gave up this opinion. There was also a suggestion to disassemble the warship and transport it overland to the Yellow River before assembling it and launching it, but it was also rejected because the project was too large, time-consuming and labor-intensive.

Therefore, the strategy adopted by the Jin army was to mobilize merchant and fishing boats on the Yellow River to cross the river, which was undoubtedly the most economical and practical method, but the attack power was greatly reduced.

Perhaps, this is the only good news for the Shu army.

In the past two or three years, Huang Chong has been ordered to garrison Pubanjin, never crossing the Yellow River for a single step, nor allowing the Wei and Jin armies to set foot in Hexi for half a step. The Wei and Jin defenders on the other side of the river also seemed to have no intention of getting involved in Hexi, and their task was to hold the Pujin Pass and prevent the Shu army from setting foot on the east side of the river.

Huang Chong knew very well that this tacit understanding between the two sides could only be temporary, and in Pubanjin, sooner or later there would be a big war, and for this big war, Huang Chong began to prepare very early.

First of all, it is to build the Guancheng of Linjin Pass, the defense of the entire west bank, Linjin Pass is the core, the east gate of the Guancheng, built by the river, out of the east gate, is the Yellow River crossing, so the gain and loss of Linjin Pass is related to the success or failure of the entire battle of Pusaka. Because the Linjin Pass was originally in the interior of the Wei State, the most recent major war, but also can be traced back to Cao Cao and Ma Chao for the battle for the Guanzhong and in Pubanjin that battle, only a finger counted, it was also more than 50 years ago, the strategic position of the Linjin Pass declined, naturally it was no longer valued, the city was dilapidated, there were no soldiers stationed, in addition to the bustling business travel, the two sides of the ferry were bustling, and the Linjin Pass was no longer a little bit of Xiongguan dangerous appearance.
