Seeing that Murong Hao and the military generals under his command were deeply worried, Murong Ke thought for a moment, looked at the map of Liaodong hanging in the main hall, and analyzed: "Father, there are two channels for the army of Zhao to transport grain, one is from Yecheng to Guò by land to Liaodong, and the other is along the sea route, from Piaoyu to Bintu, these two roads are naturally the most convenient and reliable sea transportation, but the grain transported by sea must pass through Bintu City, now, Bintu City is guarded by 50,000 warriors of my Dayan, and it is not easy for the Zhao army to break through Bintu, If you want to maintain the needs of the front-line army, you must at least use hundreds of thousands of people to transport non-stop transportation to solve it, such a fragile grain route, once attacked, the front-line army will have no food to eat. ”

Murong Hao and the generals under his command nodded frequently when they heard this, they naturally understood the fragility of Shihu's grain route, as long as an army of thousands of people and horses could cut off its grain route, but at this time, Murong Hao's hands no longer had many troops that could be mobilized, and the remaining 20,000 troops had to bear the heavy responsibility of defending the Great Thorn City, and the 50,000 troops in Bintu City could not be mobilized.

"But we don't have any extra troops, not at all." After Murong Hao finished speaking, he looked at Murong Ke helplessly.

Murong Ke pondered for a while, and said: "Father, cutting off the enemy's grain route is related to the victory or defeat of our army, and we can draw thousands of troops from the 20,000 troops guarding the Great Thorn City. ”

"What, draw the defenders of Great Thorn City." As soon as Murong Ke said this, he was immediately shocked, and the Wenchen generals in the main hall were all stunned.

"Shi Hu's main army is enough for more than 100,000, and our army's 20,000 troops to defend the Great Thorn City are already insufficient, if thousands of soldiers and horses are transferred, the pressure to defend the city will be even greater." Murong Ping was the first to come out and object.

"Yes! The defenders are already slightly insufficient, and if thousands more soldiers and horses are transferred, the Great Thorn City will be in danger. A civil servant chimed in.

"Your Majesty, it's better to transfer back half of the soldiers and horses of the northern defense Fuyu and Yuwen clans." A military general built yì road.

Murong Hao naturally knew that the troops defending the Great Thorn City were already very insufficient, and if he transferred troops and horses, the pressure on defending the city would be greater, but he would never dare to transfer troops from the north, after all, the grasslands in the north were his last retreat, and he could not lose them.

But cutting off the enemy's grain route is extremely important, which is related to the victory or defeat of the war, Murong Hao thought for a while, frowned at Murong Ke, and asked softly: "Ke'er, how many people do you think can be transferred to cut off Shi Hu's grain route." ”

When Murong Ke heard this, he said: "Father, Shihu has been fighting for many years, so he naturally understands the importance of the grain route, there must be a large number of guards along the way, and our army has too few people and horses to play a role at all, at least five thousand elite horsemen must be allocated." ”

"So much." Murong Hao was taken aback when he heard this, and the hundred officials in the main hall also widened their eyes in shock.

When Murong Jun heard this, he looked at his younger brother with great approval, and then said: "Father, the fourth brother is right, our army should allocate 5,000 elite cavalry to hunt with the Zhao army, so that the Zhao army will be able to force the Zhao army to retreat without food." ”

Seeing that the prince also thought so, Murong Hao hesitated for a while, and said to himself: "Right now, there are only 7,000 elite cavalry in the Great Thorn City, and if 5,000 are transferred, there are only 2,000 left, and the remaining 10,000 cavalry are not well-trained elite soldiers, can the city still be defended?" ”

Murong Hao's worries were not unreasonable, and the allocation of five thousand elite cavalry was equivalent to weakening half of the defense force of Great Thorn City, which had to make him cautious.

"Father, in order to defeat Shi Hu and for the future of my Great Yan Kingdom, I have no choice but to take this dangerous step." Murong Jun looked very confident.

"Which general is willing to lead his troops behind enemy lines." Murong Hao's heart fluttered and asked loudly.

General Mu Yugen clenched his fists and said: "Your Majesty, the last general is willing to go." ”

"Okay." Murong Hao looked at the map and ordered loudly: "General Mu Yugen, you lead five thousand elite cavalry to infiltrate Longshan in the northwest direction of Great Thorn City, and ambush in the mountain for a few days, and when Shi Hu's army surrounds Great Thorn City, you immediately lead five thousand elite cavalry to attack behind enemy lines, and you must not let Shi Hu's grain route unblocked." ”

"The king can rest assured that the last general will definitely live up to his mission. General Mu Yugen said with confidence.

"Well, you go and prepare!" Murong Hao said that he was still very relieved to hand over this important task to Mu Yugen, who had experienced a hundred battles.

Mu Yugen received the order and immediately left the palace hall and went to the military master to prepare.

After the transfer of the elite five thousand elite cavalry, the pressure of defending the city suddenly doubled, and the original strategy of defending the city naturally did not work.

The materials for defending the city must be doubled and hoarded, rolling wood, stones, fire oil, and other materials are transported to the city as much as possible, and the one-zhang wide city wall naturally cannot put so many things, so the soldiers who defend the city and the people work together to transport stones and clay from outside the city, step up the widening of the city wall, and even the moat is repairing and widening.

With such a huge amount of work, they had to complete it in two days, because Shi Hu's army should have arrived in two days.

Just after midwinter, the weather is still very cold, stones and soil are mixed together, as long as a basin of cold water is poured, it will soon condense into a hard lump, which is a good thing for the soldiers and civilians of Yan who need to speed up the widening of the city wall.

When danger comes, people will always burst out with amazing energy, and with the efforts of the military and civilians of Great Thorn City for two consecutive days, the defense of Great Thorn City can be described as a new look, and it is not an exaggeration to say that the defense power has doubled.

######

Two days later, Shi Hu, the king of Zhao State, personally led the main army of more than 100,000 people, and the more than 10,000 men and horses in the vanguard had already tentatively launched several rounds of feints against the Great Thorn City.

After a few rounds of feints, Shi Hu was surprised, he didn't expect that the Great Thorn City, which was far away in Liaodong, would be so tightly defended, only from the perspective of defensive ability, it was not much inferior to Yecheng.

If you want to capture the Great Thorn City, I am afraid that you will have to pay a great price, Shi Hu has a trace of hesitation in his heart, but face seems to be more important, he has already led the troops here, if he does not achieve victory, it seems too embarrassing to retreat.

In order to force Murong Hao to surrender, Shi Hu sent envoys many times to issue ultimatums to Murong Hao, but Murong Hao, who had made up his mind, completely ignored Shi Hu's request and even humiliated the envoy of Zhao in person.

The envoy of Zhao State was wronged, and naturally added fuel to Murong Hao's arrogance to Shi Hu, who was furious and decided to storm the Great Thorn City.

In order to completely crush the Yan army's will to resist and reduce its own losses, Shi Hu asked the main army to attack the city on three sides, leaving only the north gate unattacked, and not even a single soldier was dispatched.

Shi Hu's plan of 'encircling the army must be que' was not badly used, but Murong Hao quickly took measures, he sent a thousand elite soldiers to guard the north gate, and if any soldiers dared to escape, they would be killed.
