When Su Jing and the others got together, it was already half a month later. According to the intelligence, Su Jing refined a large number of siege equipment samples, and when everyone got together, Su Jing placed the samples one by one in the open space in the camp, and asked the qi refiner to explain to Princess Sanssouci and others.

At the same time, there is also a recruit battalion of the Six Dao Divine Soldier Army. A large battalion of 40,000 people is divided into eight battalions, of which 5,000 people are pure veterans, and the remaining seven battalions are a one-to-four mix of new and old soldiers.

In this way, the usefulness of the communication device originally designed by Su Jing is highlighted.

The communication equipment of the original army has reached the level of Xiaoqi, that is, the officer who commands 200 people, so that he can directly receive the order of the commander-in-chief. And Su Jing's communication device, theoretically, every soldier can receive orders. In practice, it is the squad leader of the ten-man array who can receive orders and give specific answers.

Communication equipment, the original army has done very well, but the original Tianyi calculated, if you want to achieve the scale of use of Su Jing, it is not cost-effective for the original family to make it themselves, it is best to buy it from Su Jing in order to save it. The number of savings is at least fifty percent, and if Su Jing concedes profits, he can save more than sixty percent of the cost.

Yuan Tianyi finally understood how Tang He and Mu Yinyan got mixed up with Su Jing.

Together with Su Jing, almost all wars can reduce costs and increase the victory rate! Su Jing did not embarrass Yuan Tianyi, and agreed to come down to transform equipment for Yuan Tianyi.

If you just add communication equipment, this project is not too big. The most important question now is how to leap over the abyss.

The abyss is still two hundred zhang away from the city wall, which is almost five hundred meters.

For an army of millions, these five hundred meters are too narrow.

Forced through. If the position is arranged, at most tens of thousands of people, one place will be filled, and the attack on the opponent's city head should be considered, and the soldiers on the position are too dense, and they will be sent to death. And also to guard against the enemy going out of the city to attack.

The White Tiger Divine Soldier can't be used yet. And Su Jing's White Tiger Heavy Horse was only a thousand, because he couldn't return to the White Tiger Spear Flag space, Su Jing had to refine a White Tiger Flag by himself, barely accommodating this thousand White Tiger Heavy Horse.

In this case, if the White Tiger Heavy Rider wants to advance, it will be even more difficult. Not only that, but because of the loss of cultivation space, if this thousand white tiger heavy horses were defeated, the recovery speed would be quite slow. It can no longer be used as a regular class.

Su Jing didn't bother with this, but refined a huge earth-traveling boat. Of course, this ship is a soldier's thing, and it is a theoretical siege equipment, and the soldier didn't build it back then. Su Jing was refined by combining the drawings of the Five Elements Cannon, plus the principle of floating warships.

A 100-kilometre ship could transport a large battalion of 40,000 soldiers at a time. Crossing the abyss and leaping over the city walls is not a problem, but there are dense spell towers behind the city walls. It can easily shoot down a ship that flies at an altitude of only 100 feet.

Once the ship was destroyed, there were 40,000 people on it. At most, a few thousand survived, and the rest of the ordinary soldiers were all going to fall to their deaths.

In addition to the earthly boat, Su Jing also prepared equipment such as Hongqiao, Flying Kite, and Demon Suppression Tower. All in response to this siege.

Yuan Tianyi saw these equipment, carefully inquired about the use method and attributes, and pondered. This attack is the most difficult in all previous battles, but it can be a real trouble. It's just the temple in the city, and the magic towers in the city.

In this No. 4 city, there may be more than four hundred spell towers, and the threat of each spell tower is equivalent to the Jindan powerhouse standing there, controlling an area of more than a mile radius.

There are not many strong men on hand, and if you attack hard, you will lose a lot. In other words, if he didn't join forces with Su Jing at the beginning, he really didn't have the ability to take down this city.

After a long discussion, they finally chose eight new types of equipment, and then planned a plan for the battle and began training.

For this, the Qi Refiners built the city overnight, and established a city of comparable size at a distance of a hundred miles east of City No. 4, except for the absence of spell towers and abysses, the rest of the city defense specifications were all in a one-to-one ratio.

Of course, the enemy's weapons were not counted, and the six men played different roles and underwent ten days of training, specifically to familiarize the soldiers with how to attack City Four.

This is the run-in period, the time is too short, Su Jing can't help it, if he doesn't attack again, all the big families and Dao Palaces in the South China Sea will send the main force over.

He delayed these days also to update his equipment, mainly Sword Twenty-One and Sword Twenty-Five refining sword bags for his elite soldiers. Without the sword bag, there would have been a lot of losses in this battle.

Ten days passed, no one could wait, six people joined forces, each of them sent out 400,000 troops, which is 2.4 million troops. It sounds like a lot, but in fact half of them have to be distributed in different directions, to stop the enemy's reinforcements, and to do a diversionary offensive.

In this case, the number of people left for frontal attack is still only 1.2 million.

This 1.2 million army, if you take turns to attack, it will be more than 100,000 at a time, and the width of the opponent's city wall is about eight miles.

On a width of four kilometers, 100,000 people were invested, which is not much. Even if there is a focus, it is impossible for Su Jing to strike alone at a certain point. A full-scale attack is necessary, otherwise the enemy's defense is also very easy.

The distance of a hundred miles is far for one person, but it is close for an army of millions. In just half a day's effort, the allies have already surrounded City No. 4.

The other party has no intention of going out of the city to fight, otherwise, he would not have dug such a circular abyss. The other party obviously didn't intend to do any counterattack at all, just stubbornly defended. In the face of this situation, if you want to take down the city, you are fighting for casualties.

And the believers of evil gods are not afraid of casualties. The other party also thinks the same, since the core temple does not support, then he can only use his own life to block the other party's progress.

Su Jing was not surprised, he asked Princess Sanssouci to command half of the army and go to camp in the other three directions, while himself, with the remaining 1.2 million troops, camped in the west of City No. 4.

Half a day later, the opposing coach couldn't sit still.

The location where Su Jing camped was ten miles away from the abyss. Su Jing was simply building the city, and he used Taoism and the engineering battalion to directly build a high platform on the flat ground.

The high platform of 400 zhang is a big mountain, but this big mountain is boxy, and there are slopes around it, and under the high platform, there are doors, and inside is a wide passage, and there are various stairs to reach the top.

Su Jing built the city on a huge high platform, and after the entire high platform was built, it was petrified with Taoism.

This process was so fast that the coach of City No. 4 was terrified. In a day and a half, Su Jing did everything. The other party's manipulation ability is terrifyingly strong.

The most terrifying thing is the city built by Su Jing, facing the direction of City No. 4, high and low, and more than 700 forts have been built.

After the construction of the city was completed, Su Jing pushed the army forward.

The long-range weapons of City No. 4 have an attack distance of about three miles, and even if they can deliver attacks beyond this distance, the threat is not great.

Su Jing's army, which happened to be at this distance, stopped and then dug on the spot.

The engineering battalion dug a longitudinal ravine and headed straight for the abyss. What Su Jing wants to do, the other party can't understand it, because he can't understand it, so he is afraid.

In the eyes of the coach of the No. 4 city, the abyss he designed is seamless, and even if everyone can fly, the opponent is helpless against his own defense. The amount of force above the abyss will cause all kinds of flying equipment to fall.

In the other three directions, Princess Sanssouci is also digging ravines, building large camps, assembling large equipment, and building forts as high as 100 zhang.

The strength of the engineering battalion is reflected, if it was the original army, it would not be possible to build a city and build a fort so quickly by relying on qi refiners alone. As for the engineering battalion, the professional is to do this, and all kinds of targeted equipment are complete.

Su Jing's authority is also an aspect, even if the other party has this idea, but the powerhouse of the Jindan Sevenfold Realm, is he willing to pile up mud to cast the city? Su Jing can command Ji Wushuang Iron and Soulless and let them be coolies.

Moreover, Su Jing has demon female officials, these are even more huge labor, plus a thousand white tigers are heavily ridden, and the transportation and splicing of large equipment has never been a problem.

Then Su Jing began to plant trees, planting a large number of demon trees at a distance of three miles from the city wall. With the defensive ability of the demon tree, the opponent's long-range weapon, at this distance, it is already difficult to cause damage to the demon tree.

Between the demon trees, Su Jing temporarily built a three-story Buddhist gate battle tower, these Buddhist gate battle towers have two main functions, temporary refining of stone bullets, to provide vitality for qi refiners.

Although a long-range strike from ten miles away is important, the Dryad trebuchet is the main attack. Because the stone bullet is cheap and lethal, the role in the field is not too obvious, and if you attack the city, it is a unique weapon.

The dryad was sown, and the enemy commander could no longer sit still, and immediately summoned the generals to discuss countermeasures.

The powerful mages can also see what those dryads are, and if the opponent's long-range attacks can reach this level of intensity, all the positions on the city wall are within the range of the strike, and there are no dead ends.

The commander of City No. 4 is a middle-aged woman, who is a powerful warrior in her own right, and the armor and equipment on her body are quite rare in Dongqin.

She looked around at the hundreds of generals in the conference hall, and said, "What the other party has planted is a demonic plant, and the magician has already said that the attack distance can even reach the center of the city." However, I see that the other party is arranged for the city wall, and tens of thousands of demonic plants have been planted on the front, of which there are more than a thousand, and the power is huge. ”

"Wizard doesn't know what kind of plant that is?" asked a young general. (To be continued......)
