Under the city of Gaochang, looking at the city wall of Pingchuan, all the Gaochang soldiers were embarrassed, there was no barrier of the moat, so far there was only one city wall between Gaochang and the Tang army.

Gaochang's morale fell into a trough, and the defensive advantage that originally belonged to Gaochang City was overpowered by the Tang army little by little, and this city wall alone did not pay attention to ensuring the safety of Gaochang City.

Suddenly, an anxious atmosphere slowly appeared in Gaochang City, and everyone understood that Gaochang City was probably in danger, and as for how much time was left, it depended on when the Tang army would attack.

"King Qiqi, the Tang army has filled in the trenches in front of the gates of the major cities, and Gaochang City is in danger!" A Gaochang general hurriedly came to report.

"You and the others are all a bunch of waste, watching the Tang army fill in the trenches." Koji Zhisheng was furious and scolded.

The generals of Gaochang couldn't help but show shame on their faces, and they bowed their heads one after another and said: "The ministers are incompetent!" ”

The Tang army was monitored by hot air balloons and protected by trebuchets, and the defenders of Gaochang were simply powerless to stop any movement of the Tang army.

"What are the Western Turks doing to eat, how can they not have reinforcements." Koji Zhisheng said manically, in his opinion, the Western Turks are all cavalry, and if they want to send troops, I am afraid they have already arrived.

"Back to the king, now that the various departments of the grassland are busy in spring, I am afraid that there will not be many people at all, and General Helu is also restrained by Qixin He Li, and he can't rescue Gaochang City at all." General Gaochang said helplessly.

Koji Zhisheng couldn't help but sit on the throne dejectedly, the Tang Dynasty was already determined to destroy Gaochang, but the Western Turks did not have the courage to rescue Gaochang with the strength of the country, so Gaochang fell into an embarrassing situation.

"Report! Datang sent a letter of surrender again! The envoy of Gaochang came to report with a solemn face.

"Surrender?" At this time, the hearts of the Gaochang ministers moved, and now that Gaochang City is facing a desperate situation, the resistance of the Gaochang ministers to surrender is not so strong.

Seeing the performance of the ministers, Lu Zhisheng couldn't help but twitch, and waved his hand: "Read!" ”

"Tang Jun said that if the king goes out of the city and surrenders, the conditions of the Tang Dynasty will remain unchanged, otherwise the army will attack the city, and Gaochang will bear all the consequences." The envoy of Gaochang read the surrender book concisely and concisely.

"At your own risk? Datang deceived people too much. Koji Zhisheng roared angrily.

"Think twice!" The envoy of Gaochang hurriedly persuaded. Now Gaochang City is on the verge of danger, the defensive weapons have been destroyed, the trenches have been filled, and only a wall is left to protect it, no! Now even the city wall can not protect Gaochang City, the Tang Army's hot air balloons can be set on fire in the sky above Gaochang City unscrupulously, if it were not for the people of Gaochang City to fill the water tank, Gaochang City may have been burned to ashes.

"No, I believe that the Western Turks will come to the rescue, my lips are dead and my teeth are cold, I believe that Desire Valley will not know this truth, once Gaochang falls into the hands of the Tang Dynasty, the next target of the Tang Dynasty is the Western Turks." Koji Zhisheng said stubbornly.

"But what if Gaochang can't hold out on to the Western Turks?" The envoy of Gaochang stubbornly asked all the words in his heart that he was unwilling to say.

"Then the jade will be burned, even if Gaochang City is destroyed, the Tang army will taste the pain of the skin." Koji Zhisheng roared angrily.

Ju Wentai would rather die on the throne than bow to the Tang Army, and how could Koji Zhisheng want to lose the throne that had just arrived, until the last moment, no one wanted to lose the rights in his hands.

……………………

"Back to the general! Once again, Koji Zhisheng rejected the general's kindness. In the camp of the Tang Army, Xin Fang'er reported to Hou Jun.

"I just don't know what to do! There is only one wall left in Gaochang City, which is already doomed to fall, and General Ben has not blamed Koji Zhisheng's previous resistance, and they still don't appreciate it. Hou Junji frowned.

"If you don't use a hot air balloon to carry explosives, you can blow up all the Gaochang Palaces and scare the guts of Koji Zhisheng." Niu Jin Dalang said.

Xue Wanjun waved his hand and said: "There is no point in blowing up the Gaochang Palace, in the end, it is better to blow up all the granaries of Gaochang City, lose the grain and grass, and see if Gaochang City surrenders or not." ”

Hou Junji's heart moved, but he shook his head and said: "No, the firearms supervisor will soon be able to blow up the Gaochang city wall, Gaochang City will fall sooner or later, if the grain and grass and the palace are blown up in advance, the Tang army will be needed to clean up the aftermath in the end." ”

If the Tang Dynasty captures Gaochang City, but Gaochang City has no grain and grass, the Tang Army may still be responsible for the rations of so many Gaochang people, and it is also not conducive to the Tang Army's next plan, after all, there are still Western Turks eyeing the tiger, and it is uncertain how long this war will last, and the Tang Army needs the grain and grass of Gaochang City even more.

"Anyway, there is only one city wall left in Gaochang City, and it will definitely not be able to defeat our army, and the last general will lead his troops to attack, and he will definitely be able to break through Gaochang City in one fell swoop." Xin Fang'er said confidently.

Don't look at Gaochang City as strong and tall, but it has been completely suppressed by the Tang Dynasty, and has lost its weapons to defend the city, like a toothless tiger, coupled with the cover of gunpowder, just like the field city, if the Tang army does not count the casualties, the chances of capturing Gaochang City are very high.

"No, in this case, our army will definitely suffer heavy casualties." Hou Junji vetoed again.

If it was before, Hou Junji, who was so weak in Gaochang City, would definitely not let it go, but the firearms supervisor gunpowder broke the city successfully, and there was no need for the Tang army to sacrifice so many soldiers. Not to mention that the Tang Army's key defensive object is the Western Turks, and once the Tang Army suffers too many casualties, I am afraid that it will be taken advantage of by the Western Turks.

A group of Tang generals frowned, they wanted to take over Gaochang City completely, and the best result was naturally to let Gaochang surrender, but everyone knew that Gaochang City would fall sooner or later, and Koji Zhisheng was still resisting.

At present, if the Tang army wants to reduce its losses, there is only one way, and that is to blast the Gaochang city wall with firearms, but this will take time.

"Time? Isn't it just digging tunnels, I have an army of 100,000 and some are craftsmen, and I wait for the day and night to work, I don't believe that I can't dig tunnels. Niu Jinda said grumpy.

Hou Junji's heart moved, and he asked Merton: "If you are allowed to mobilize manpower and rush to work day and night, how long will it take to open the tunnel." ”

Anyway, the gunpowder is already prepared, and it only needs to open up the tunnel, and the last thing the Tang Army lacks at present is manpower.

Merton said solemnly: "If there are enough craftsmen and manpower, and then work day and night, the tunnel can be dug under Gaochang City in three days at most." ”

"Three days!"

Hou Junji's eyes couldn't help but light up, three days, Tang Jun could still afford to wait, and said loudly at the moment: "Okay, according to what you said, three days will be three days, and after three days, this general will see the promise of ink sacrifice wine." ”

Merton stood up solemnly and bowed and said, "Three days later, if Gaochang City cannot be broken, the last general will be willing to lead the army." ”

"Good!" Hou Junji took the case and said: "In this case, after three days, if Gaochang does not surrender, blow up the Gaochang city wall." ”

Soon, the Tang army stopped all operations against Gaochang City, and even the hot air balloons hanging in the sky were lowered, and the two armies of the two warring sides fell into an eerie calm.

However, everyone knows that this is just the calm before the storm.
