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 the various mountain passes without any regularity, one moment it blows in one direction, and the next it blows violently in the other direction.

The location of Tongguan City is a big wind outlet, usually the wind is much greater than the flat land, and the wind is even greater than the plain area in the case of severe convective weather, I don't know how much, if there is a wind level to judge, the wind force is at least ten or more in an instant, 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 blew up also confused people's eyes, they couldn't open their eyes, and the bow in their hands was not easy to hold, let alone aim, and the arrows shot were no longer parabolas like usual, but fluttered with the wind, and the killing effect of the arrows decreased exponentially.

This made any general in command of the city very bitter, the killing effect of the arrows was seriously reduced, and the number of rebels who dodged the arrows would definitely increase significantly, and more and more people would climb the western edge of the forbidden ditch. There are more and more rebel soldiers gathered under the city wall, and there will inevitably be more ladders erected on the Tongguan city wall, and more rebel soldiers will begin to climb the city, which is what the soldiers defending the city at the head of the city do not want to see.

Arrows can not effectively kill the enemy, can only use wood, rolling stones, swords to hit the rebels who ascended the city, but the killing effect of these means is certainly not as great as the rotation of bows and arrows, which is almost fatal to the Tang army defending the city, and any general commanding the battle is under pressure...... All the people in the city wanted the wind to go away and the rain not to fall, and they would rather be exposed to the sun.

"Prepare your sword!" Wang Sili drew his sword and shouted loudly to tell the sergeants to get ready.

Arrows are not effective and must be dealt with in other ways.

A sergeant abandoned his bow and drew his sword, and rushed to the head of the city, ready to meet the rebels with their swords.

As far as the eye could see, there were already groups of rebel sergeants climbing the western edge of the forbidden ditch in various ways, and more sergeants were rushing behind.

Seeing that the rebels immediately took advantage of the change in weather to speed up the attack, Wang Sili knew that the difficult moment was coming.

He expected that such a situation would have occurred after dark, not now, and the difficulty had come two hours earlier than expected.

Wang Sili, who was originally very confident in holding on until the reinforcements arrived after dark, and even held on for a longer time, was a little shaken in confidence.

If the arrows are not effective, it is unknown whether the strength of the sergeants will last until reinforcements arrive.

But now there must be no retreat, no cowardice, and it is necessary to boost morale in every way, and do everything possible to repel the enemy forces besieging the city, and never allow the rebels to ascend to the top of the city. Wang Sili didn't have much to deal with, so he could only take the lead and lead a group of brave men to rush to the head of the city and block the enemy with the swords in their hands. He hoped to deal an effective blow to the rebels and eventually make them retreat.

He also has more than 200 Mo swordsmen under his command, who are very brave, and now it's time for them to show off.

"Hopefully reinforcements will arrive sooner!" Wang Sili, who rushed to the head of the city brandishing his sword, muttered a sentence.

When he rushed to the head of the city, he naturally looked in the direction of the east of the city.

He hoped that there would be no critical situation in the east of the city, and even Yang Xi had the ability to lead the army to reinforce them!

－－－－－－－－－－－－

Of course, Yang Xi saw that the arrows shot at the head of the city had greatly decreased due to the strong wind, but the attack strength of the rebels had not decreased at all, but had a tendency to strengthen, he was more anxious than anyone else, he was worried that the rebels would take advantage of the sudden change in the weather to attack the head of Tongguan City.

Of course, his concern was not that the rebels would succeed in attacking the east gate.

The direction of the east gate is small because of the small cross-section that can climb the city, the number of rebels who can climb the city will not be very much, and there will be less in the case of wind and rain, there are several cliffs in front of the city gate to isolate the wind, the city head is relatively calm, and the arrows shot under the city 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 moment ago, the 3,000 men and horses led by Dou Hua were still about fifty miles away from Tongguan City, but they were sleepy and lacked horses, and they could not gallop at the highest speed, and if there were no unexpected circumstances, it would take at least more than an hour to reach Tongguan City, two or three hours.

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 the arrows 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 terrain was in the hands of the Tang army, but now it is the other way around, the time is occupied by them, this fierce wind, and the heavy rain that is about to fall, is a means to help them succeed, and the Tang army, which has lost the advantage of arrows, cannot 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!
