"Good! Worthy of General Ben! Zhang Xun looked at the ant-attached pioneer approaching the city tower, and couldn't help but smile smugly.

Although Zhang Xun also knew that even if he attacked, it was unlikely that he would be able to fight in a battle, but ...... On the first day of the siege, it was only an hour from the beginning of the formation, and the city wall had already been climbed, and I am afraid that it would not take three or five days to defeat Qu'a!

The siege army can climb the city wall, which can be said to be a sign of the expansion of the defenders' casualties, otherwise no matter how fierce the long-range attack is, it will only suppress its hindrance to the city without troops, after all, people are on the city wall, and it is a big deal to retract it, and how much can it kill?

In a fierce attack, if you can't climb the city wall, the casualty ratio is definitely a blood loss for the besieging side.

But as long as you can enter the stage of white-knuckle battle in the city, even if you are finally driven down again, the casualty ratio will be much better, and it will deal a great blow to the morale of the defenders.

"General Chuanben will order, go to the front line to shout, and the first to ascend will be rewarded with a thousand gold and promoted to three levels!" Zhang Xun said to the herald.

This kind of encouraging herald should still be shouted, and the enemy is not afraid of hearing it.

However, at this moment, I saw a number of "big guys" appearing from the city tower.

The things covered by the curtain before were still a little bit in the middle, but after the curtain was removed, there seemed to be rollers under the things, which were pushed to the side of the city wall one by one......

I saw that it was a large wooden board with two or three people's arms wide and horizontally and vertically, with a cold light shining on it, densely covered with wolf fangs with the length of a small arm, and at this time, the spurs were hanging obliquely downward, and there were ropes and cantilever hanging behind them!

"Rolling logs? No, a little trickier than rolling logs...... It doesn't seem to be completely unprepared! The herald will reward 3,000 gold for those who ascend first, and 100 households will eat it! Zhang Xun was a little nervous, but he wasn't too anxious.

"Put!" The commander on the city wall, under the command of Chen Gong, shouted while waving his flag.

A row of huge planks, bald along the city wall, slapped horizontally - wolf tooth slap, a kind of city defense equipment, simply put, a huge nail plank, after the shoot down, pulled back with a roller, reused, used to attack the enemy army attached to the ant and the enemy under the base of the city......

However, there are some differences in the main body style of the wolf tooth slap in the white picture, and there is also a beveled template on the back, which is similar to the wedge-shaped block that fits the city wall, so that under the gravity deviation, it is not a horizontal shot, but along the city wall, all the way down obliquely, and the wolf tooth thorns are also oblique, perpendicular to the ground.

Therefore, Bai Tu called this thing "wolf tooth scare", and after releasing it, it was not filmed, but all the way down!

What's more...... What pulls the wolf's tooth is not a simple wheel, but a "fairy gourd" - a combination of pulley block and bearing, a lifting tool.

Pulleys have been used in the Warring States period, but they are all fixed pulleys that change the direction of force, and the pulleys at this time are called "pulleys", and when the moving pulleys are used, Baitu does not know, but there is no difference in the process.

Bearings, in fact, are wheels, which are used earlier......

Although the craftsmen did not understand the principle, they still followed what Bai Tu said, and finally made a "fairy gourd" that was very bulky compared to modern chain hoists.

This is also something that the craftsmen of Qu'a have been trying to make molds for a long time at the beginning, otherwise it is just a large wooden board nailed up, with wolf tooth thorns, even if a wedge-shaped structure is added, it is only a clever thought, and it is not technically difficult.

It's just that the wolf teeth of normal production are not as neat as they look in front of them.

After they install the city tower, it is like a cold weapon loaded on the general's armor, it will become very black technology, these city defense equipment after the city wall is installed, there are also changes, but not as excessive as the armor weapon, it is said that this is related to the defense of the city itself, the higher the city defense index, the higher the effect of the same city defense equipment.

The soldiers who had already trained the use of equipment, after another command to "collect", quickly pushed the grinding disc-like roller, and the other end of the roller was a pulley, which was vertically connected to the fairy gourd.

I saw that under the power of this "fairy", the originally heavy wolf tooth slapped quickly rose back!

The normal wolf tooth beat, when pulling back, even if the roller is used, is very cumbersome, not to mention the wolf tooth shoot of the white picture, there is also an inclined plank along the city wall, and in order for it to be able to stick to the city wall, a counterweight is also added......

If you pull it up slowly with a wheel, you can cut the rope with only a few thugs below, and even catch up with the side without wolf fangs!

However, the scene in front of me ......

Zhang Xun: !!?

Zhang Xun looked surprised - what happened? How did such a big weight go up so quickly?

Not long after Bai Tu arrived in Qu'a, the people's hearts were attached, not to mention that Qu'a was just an ordinary city, and it was not a huge pass for the defenders, even if the people wanted, it would not be so terrifying to the bonus of the city's defense equipment, right?

The soldiers below didn't react, the ants attached to the wall, and the queue that was about to approach the edge was now beaten down, and they were either stabbed or slammed, and most of them couldn't survive.

As for bows and arrows and the like, the impact on this bulky "wolf's tooth" is really limited, the fairy gourd on it is fine, but the gourd cover outside is not a decoration, and the bow and arrow can't shoot so high and pierce through the baffle.

I can only watch as the wave of "wolf teeth" that has just been harvested is quickly taken back!

"Change formation! Half-moon style! Zhang Xun's face became gloomy.

I saw Zhang Xun on the high platform, after ordering the flag bearer to give a banner, several arrays of the military formation rotated and began to change, and the original front array retreated to the second line at this time, and at the same time, the left and right wings became more even.

Even the original recess of the moon rushed forward with a column of men and began to want to attack in an all-out way!

However, Zhang Xunjun's morale has dropped significantly after the previous "wolf tooth scolding......

Bai Tu also intuitively saw the importance of "morale", only to see the enemy army besieging the city, not only seemed to have much less strength, and was more sluggish to orders, but more importantly, he became hesitant when climbing!

Nearly an hour later, it was necessary to use the wolf's fangs again.

And when Zhang Xun verified that the wolf's tooth can be reused at the cost of hundreds of people, he found that it was already the middle of the solstice, and when the soldiers raised their heads to attack the city, it was already a little dazzling, so Mingjin withdrew his troops......

Seeing the Huainan army retreating outside, a burst of cheers sounded on the city tower - the casualties of the defenders were not serious, and the source of most of the soldiers was still from Danyang, so the morale did not drop but rose.

However, Bai Tu and Chen Gong understood that this was only the first step!

Sure enough, in the afternoon of the same day, when the sun began to turn westward, Zhang Xun still had no intention of resuming the attack, and the scouts came with the news that the Huainan army began to cut wood and collect materials from the foothills outside the city......

"It seems that Zhang Xun's mind is clearer, and he is going to build a ladder." Chen Gong said.

The ladder is also a siege equipment that existed during the Warring States period, and it is not a simple long ladder, at this time, the ladder is generally with wheels below, and the upper part is a folding wooden ladder that can be pitched up and down, and the soldiers below rely on the winch, which can make the upper half of the ladder that originally fell down be pulled up and put on the city wall.

After that, the soldiers could climb up by means of a diagonal ladder, although the craftsmanship was limited, and the besieging side was still unfavorable, but it greatly weakened the advantage of the city wall.

The defenders of the city sometimes have to consider going out of the city to meet the enemy and destroying the ladder, otherwise the danger of losing the city wall will be greatly increased!

Generally, when attacking a city, a ladder will be built with local materials, anyway, there are many wild trees at this time......

"Will Zhang Xun accept it?" Bai Tu asked curiously as he looked at the letter written by Chen Gong.

"Nine times out of ten." Chen Gong said.

And Zhang Xun's side, who had just started to take the ladder and worked all afternoon, suddenly came from outside: "General!" There are enemies shooting from outside......"
