The wind showed no sign of abating, and it was blowing louder and stronger, and the dark clouds in the sky began to roll sharply, and soon it was dark.

The wind blows from all the mountain passes, without any regularity, one in one direction, and the other in the other.

Tongguan City is a big wind outlet, usually the wind is much greater than the flat land, not to mention the severe convective weather, the wind is even greater than the plain I don't know how much, if there is a wind level to judge, the instant wind is at least more than 10 levels, or even greater.

Even the tiles on the tower of the city gate were blown down by the wind, and some small trees were broken by the wind.

The sergeants at the head of the city were blown to the ground, and many of them were unable to stand, and even collided with each other.

The dust and sand that blows up also confuses people's eyes, and even their eyes can't be opened, and the bow in their hands is not easy to hold, let alone aiming, and the shooting and arrows are not the usual parabolas, but as they drift around, the killing effect of the arrows decreases exponentially.

This made any general in command of the city cry bitterly, the killing effect of the arrows has decreased so much, the number of rebels rushing over will definitely increase, and the number of people who climb the western edge of the forbidden ditch will also increase exponentially. If the number of rebels on the western edge of the forbidden ditch increases a lot, there will inevitably be more ladders erected on the wall of Tongguan, and more and more rebel sergeants begin to ascend the city. This is what the soldiers defending the city do not want to see.

Arrows are not effective in killing enemies, and can only be used to hit rebels who ascend the city with wood, rolling stones, and swords, but this is certainly not as effective as a large-scale bow and arrow shot. If you want to fight with swords, it will be white-knuckle combat.

If you start a white-knuckle battle with the enemy, you will definitely suffer from the small number of personnel.

Everyone just wanted the wind to go away and the rain not to fall, and they would rather be exposed to the sun.

When the wind blows, the heat disappears, and some water vapor blows, which makes people feel cool, and the rebels also have such a feeling, and the benefits for both sides are the same. But the arrows could not be fired effectively, which was almost fatal to the Tang army defending the city.

In the current situation, it is almost the defenders at the head of the city who shoot arrows at the rebels who are besieging the city, and even if the rebels who are besieging the city have the ability to shoot arrows, they do not pose a great threat to the defenders at the head of the city, after all, one is shooting downwards and the other is shooting upwards, and the killing effect caused by the drop is very large, and it is not possible to shoot at the head of the city while standing in the forbidden ditch.

But there is no way to help people, you can only overcome, the arrow still has to be shot, no matter whether it has an effect or not, how lethal it is, this is the most powerful move to kill the enemy. In Tongguan City, there is no shortage of arrows, and with the consumption just now, more than 10,000 people can use it for at least a month, or even longer. After all, there are not many times to use arrows at such a high density as just now, and if it continues at this speed, then the hundreds of thousands of horses besieging the city can all be shot within a few days, as long as the Tang army sergeants are not exhausted.

"Prepare your sword!" Wang Sili, who had already ordered a sergeant to abandon the bow and use the sword, waved the war knife on his body at the same time, and shouted loudly to the sergeants, ready to kill the enemy with a knife.

As far as the eye could see, there were already groups of rebel sergeants using various methods to climb the western edge of the forbidden ditch, and there were more sergeants rushing behind, and Wang Sili knew that the time for great persistence was coming.

He expected that such a time would have started after dark, not now, which was about two hours earlier than expected.

Wang Sili, who was originally very confident in holding Tongguan City until the reinforcements arrived after dark, his confidence was a little shaken. If they continue to fight the enemy in this way, it is unknown whether the strength of the sergeants will be able to hold out until reinforcements arrive. But now there must be no retreat, no cowardice, and it is necessary to boost morale in every way, and to do everything possible to repel the enemy forces besieging the city.

Of course, Yang Xi saw that the lethality of the arrows shot from the city had dropped significantly, but the strength of the rebels' attacks had not decreased at all, but had a tendency to strengthen, and he was more anxious than anyone else.

Of course, he was not worried about the direction of the East Gate.

The direction of the east gate is small because of the small cross-section that can climb the city, even if it is windy and rainy, the number of rebels who can climb the city will not be very large, and there are several mountain cliffs separated by the wind, the rebels rush to the bottom of the city, the arrows are still lethal, and the existing strength can be enough to defend against the attack of the rebels. What he is worried about is the direction of the South Gate, although the direction of the South Gate has the largest number of troops, about 8,000, but in the face of the continuous siege of tens of thousands of rebels, the troops are still at an absolute disadvantage, but he has not many troops to reinforce, unless a large number of reinforcements arrive.

Where's the reinforcements? When can I arrive at Tongguan City?

Yang Xi sighed in his heart! According to the urgent report received a while ago, the 3,000 men and horses led by Dou Hua are still about fifty miles away from Tongguan City, but they are sleepy and lack of horses, and they can't gallop at the highest speed, if there is no accident, it will take more than an hour or two hours to reach Tongguan City. Now there is a strong wind again, and it may rain heavily in a while, and the arrival time in Tongguan will definitely be delayed.

"I hope that the soldiers will work together to kill the enemy desperately and prevent the rebels from attacking the city!" Yang Xi muttered silently, and immediately ordered Yang Dong, the leader of the guards, to assemble all the guards generals, and if necessary, he would lead this private army, as well as five hundred sergeants in reserve, to reinforce the direction of the south gate.

Cui Qianyou, who was standing on the west edge of the forbidden ditch, also saw that the arrows shot at the head of the city were blown away by the wind, and the lethality of his own men and horses besieging the city was greatly reduced. In the direction of the south gate, all troops were poured in, and the attacks continued to give the Tang army at the head of the city any respite.

"Order the generals, speed up the attack, no matter what the price is, you must rush to the head of Tongguan City!" Cui Qianyou, who was wielding a war knife, roared angrily at the lieutenant generals and sergeants beside him: "Whoever is the first to attack the city, the official will be promoted to the third level, and the reward will be ten thousand yuan, and the commander will personally ask His Majesty for credit!"

"Kill...... Pull ...... "Cui Qianyou's adjutant generals, sergeants and personal soldiers all waved the war knives in their hands and roared.

Originally, the time and the terrain were in the hands of the Tang army, but now, the time of the day was occupied by them in turn, and the strong wind blowing and the heavy rain that was about to fall were the means to help them succeed, and the Tang army, which had lost the advantage of arrows, could not stop their continuous attacks no matter what.

Nearly 1,000 people have escaped the blows of the Tang army's arrows, climbed the west edge of the forbidden ditch, and set up the cloud ladder on the city wall.

The wind continued to blow wildly, knocking down the ladders that had been erected, but more ladders leaned against the walls.

Lightning and thunder are becoming more frequent, cloud pressure is getting lower and lower, and the sky is getting darker.

Finally, in a series of earth-shattering thunder and lightning, a heavy rain fell from the sky!
