Under Suiyang City, tens of thousands of Taoqiu troops gathered, and everyone was waiting for the lord's order to decide what to do next.

For a city like Suiyang, which has a high wall, it is like a fortress and has a reputation that is difficult to conquer. But if Dai Yan didn't even make a tentative attack, then he would underestimate his opponent too much, and it would also be a blow to the morale of the soldiers under his command!

With the strong transportation capacity of the sailors, the Taoqiu army soon transported hundreds of ballistas to Suiyang City, and lined them up densely near the south gate of Suiyang. Subsequently, Dai Yan also mobilized all the bed crossbow troops that had been engaged in field battles on the battlefield to Suiyang City.

Hundreds of ballistas, and even thousands of bed crossbows placed under Suiyang City, immediately gave people a strong pressure! Not only the soldiers defending the city in Suiyang City, but even the soldiers of the Taoqiu Army under the city were also inspired by the powerful forces placed under the city, and their morale was high! The entire Taoqiu army, just waiting for Dai Yan's order, can attack the city!

Under the command of Dai Yan, hundreds of ballistas began to be launched, and powerful stone bullets were thrown out and smashed into Suiyang City, smashing Suiyang's southern city into pits of different depths, causing a lot of damage to Suiyang's city wall. As for the female wall above the southern city, under the powerful attack of the ballista, most of them were also damaged!

After the attack of the ballista, the arrows fired by the bed crossbow were shot one by one on the city wall, and the entire southern city was filled with the arrows fired intensively, like a wooden board full of nails!

Although the city wall of Suiyang City is more than ten meters high, the southern city wall full of arrows is like a city wall full of stairs in the eyes of the army under the city, and there is no longer the strong sense of oppression brought by the majestic city before!

For Dai Yan, the siege battle was the battlefield that tested the courage of the soldiers. In such a battlefield, he would not send a large number of cannon fodder to force them to attack the city, as the previous wars of the nations did. From the very beginning, he used the most elite soldiers and offered extremely high rewards as rewards!

Thousands of carefully selected siege soldiers, led by the bravest officers, began to charge towards the southern city wall as the drums sounded on the battlefield!

When the soldiers reached the foot of the southern wall, they immediately climbed up with the help of their arrows. Some people who are skilled climbers can even climb up as quickly as they would a staircase, along a diagonal arrow!

And under the city walls, the ballistae that had begun to attack the towers gradually began to stop attacking. Only a few of the ballistae in the front row began to adjust their angles and start attacking after aiming directly at the walls!

The one who really covered the soldiers from climbing the city wall was still the bed crossbow troops! These bed crossbow troops, after shooting the treadmill arrows, began to collectively change arrows, and all used light arrows to attack the soldiers of the Suiyang Army on the city wall!

After losing the cover of the female wall, the bed crossbow has greatly enhanced the deterrent effect of the defending soldiers on the city tower! Any soldier who dares to stand on the city wall is likely to be subjected to one-on-one fire from the ground bed crossbow troops!

Under the cover of the ground forces, the first soldiers to attack were able to reach the city wall directly! For these Taoqiu soldiers who climbed the city wall, the city defenders immediately began a fierce counterattack!

Armed with short swords, spears and halberds, they engage in hand-to-hand combat with the Taoqiu soldiers who ascend the towers! As for the soldiers who had not yet climbed the tower, they also reacted quickly, and immediately threw all kinds of stones, rolling logs, etc. down to attack the Taoqiu soldiers! Some are even more ruthless, and even directly use boiling water or even gold juice to attack!

For the first round of siege attacks, Dai Yan was still very satisfied with being able to climb the Suiyang City Tower! When he saw that Suiyang City Tower didn't have very good defensive weapons, he even had the idea of directly attacking this city in one go!

However, as soon as he smelled a scent, he immediately gave up on such an idea, and began to withdraw his troops, intending to make the soldiers who had climbed the tower retreat!

This smell may only be familiar to Taoqiujun who withdrew from the Xiangyi Industrial Zone before, but Dai Yan, as a traverser, is also very familiar, this smell is the smell of asphalt! Suiyang actually has such a weapon as asphalt that can be defended!

When Mingjin's voice sounded, Dai Yan could clearly feel that the Taoqiu soldiers on the city tower were a little unwilling, and seemed unwilling to retreat, after all, with the high reward offered during the siege of the city, it was definitely a rare high price during the entire war! However, under his continuous orders to retreat, all the besieging soldiers retreated according to the order.

These soldiers didn't know that Dai Yan had ordered the retreat at such a fast speed for their own good, and they even retreated from the city wall in a slow manner with certain emotions, with a reluctant attitude!

Those who were reluctant and retreated slowly soon reaped the bitter fruits! Once the pitch is melted at a high temperature, the viscous object of the asphalt is like a liquid! Such a liquid thing, pouring down from the castle tower, caused an astonishing reaction!

Those stepper arrows that were stained with asphalt immediately began to be surrounded by this viscousity, and a few of the crossbow arrows were even directly ignited by it!

More asphalt poured on the Tau Hill soldiers who were withdrawing their troops, and these soldiers immediately let out a terrible roar, and the endless pain devastated their bodies and minds!

Looking at these miserable soldiers who were covered by asphalt, Dai Yan was also a little helpless. This kind of thing, even in the afterlife, is not easy to contaminate, and he doesn't treat it in a very good way!

The only thing to do is to send a medical team to the bottom of the city tower, take off all the clothes on these soldiers, and peel off the asphalt as much as possible, and at the same time carry out all kinds of medical treatment! For these soldiers, after this asphalt attack, it is almost impossible for them to go to the battlefield again.

In such a short period of time, he lost hundreds of brave and excellent soldiers, which also made Dai Yan extremely painful!

The first tentative attack of the Taoqiu army, although it did not do its best, almost used the most effective means of the Taoqiu army's siege. Under these means, he easily tested Suiyang's defensive weapon asphalt, which also surprised Dai Yan.

In Dai Yan's mind, in the case that he did not find a second traverser in the world, the asphalt of Suiyang is most likely to come from the original Xiangyi Industrial Zone. After all, the Chu army and the Suiyang army are allies, and some specific weapons must be shared with the Suiyang army. Thinking about these asphalts, it should have been secretly transported from the south bank of Suishui to the north shore by a small number of ships when the Taoqiu Naval Division went south on a large scale to fight the decisive battle with the Huaishui Naval Division of the Chu Army!

When they were in the Xiangyi Industrial Zone before, Taoqiu's caravan used this weapon to inflict extremely heavy casualties on the Chu army, and now it is really retribution, and it is Taoqiu's soldiers' turn to enjoy the damage caused by this weapon!

This also made Dai Yan recognize a law: once some weapons that should not appear in this era are popularized on the battlefield and produce excellent results, it will inevitably quickly spread to the whole world!

Today, Taoqiu's standard bows and crossbows, as well as bed crossbows, ballistas and other weapons, have achieved excellent results in the battle with the Suiyang army. It is not long before these weapons will inevitably be learned by all countries and popularized in the army! After all, the army is the most conservative place, and it is also the most efficient place!

This also reminded Dai Yan of the well-known Nobel Prize in later generations. After Nobel invented explosives, this weapon with great lethality immediately began to spread throughout Europe, and then to the whole world! Such a thing may be inconceivable for a conservative army, but in the army, any weapon that can increase the combat effectiveness of the existing side will inevitably be quickly popularized!

The appearance of asphalt also made Dai Yan pay attention to the leakage of military secrets in Taoqiu! Now that he's a traverser, he's facing enemies that are living people, not brainless NPCs, and with a little bit of brain, they'll learn from Taoqiu's advanced military industry to strengthen themselves!

How to be able to lead the opponent in the military industry, then there is only deeper industrialization, so that the military industry will become more powerful with the industrialization of the entire Taoqiu system! Dai Yan can also understand the reason why the industrialized countries of later generations, once they start industrialization, can't stop at all: there are several opponents chasing you behind, once you stop and are surpassed by the opponents, it is the time of death! The road to the rise and development of such a country is such a desperate road that can only move forward and cannot go back!

It is no wonder that Britain and France in later generations were forced to be hostile to Germany and launched a war to prevent Germany from rising!

With the advent of asphalt, Dai Yan's mind immediately thought of many future statecraft. However, he instantly left these strategies behind, and whether all these strategies could be realized or not still needed for him to capture the fortified city in front of him!

After all the besieging soldiers had retreated, he immediately stopped his tentative attack on Suiyang. In his opinion, a city with a strong defensive weapon and a strong sense of defense, even if it is conquered by force, it will inevitably cause great losses!

For a city-state like Taoqiu, and when the core population is already small, forcibly breaking the city in such a way, even if it can break the city, that kind of loss is definitely something that Taoqiu can't bear!

What he wanted to do more was to break the city from within!

Subsequently, Dai Yan did not have any more action against Suiyang except for sending a small number of soldiers to stay near Nancheng to keep an eye on Suiyang City, and to prevent the soldiers from destroying the arrows on the city wall by the Suiyang army.

He recalled all the generals of the Suiyang Army and asked everyone to brainstorm and discuss how to break through the city from the inside!

He called this siege plan the battle of the heart!
