This is a large ballista that has never been seen before, fired from a hundred and fifty zhang away, and the crossbow arrow with the thickness of a child's arm is shot out by a spiritual light visible to the naked eye, and the momentum is extremely fast.

The small magic arrays deployed at the gates of each city could not block the impact of the giant crossbow at all, and the huge crossbow body shot at the head of the city, most of which were directly nailed to the city wall, and were inserted three feet into it, causing damage to the city wall, and some flew directly over and shot into the city.

The defenders on the city wall immediately intercepted, and a Jindan monk flew out of his long sword and slashed up against the giant crossbow, the long sword slashed on the crossbow rod, and was directly knocked out seventy or eighty zhang, far away somewhere in the city, this Jindan divine consciousness was injured, and immediately spit blood from his mouth, his face turned pale, and he was injured on the spot.

The giant crossbow was slashed by the flying sword, and it spun diagonally through the air, sweeping across street corners, and half of a house was blown apart.

The power of a crossbow is so powerful!

When Gu Zuo raised troops to fight against Xian Yuxiang, he also got a batch of "scrapped" crossbows from Chen Xuanli's Longwu Army Arsenal, and showed his skills in the ambush of Mengle Mountain. This kind of crossbow is also known as a hand crossbow, operated by a single person, and the arrow is only one foot long, using the tendon skin of the demon beast as a twisted string, and the arrow is made of special gold and iron, with the effect of armor piercing.

This is the prevailing standard crossbow in the Tang Army, the most exquisite batch, by the Ministry of Industry Craftsman Supervisor in Chang'an's workshop refining, these days, the craftsman supervisor day and night to make, has been equipped with 1,500 pieces for the North and South Ya forbidden army.

Gu Zuo once thought that the Chang'an Forbidden Army was the only one in the world in terms of guarding the magic weapon, even if the combat experience was sparse and the fighting will was weak, with excellent magic armor and magic weapons, it could also perform. Unexpectedly, I saw the heavy crossbow used by the rebels today, and my self-confidence was hit hard.

Regarding heavy crossbows, Gu Zuo had not thought about refining a batch in the past, but after understanding the principles and methods of supervising the production of crossbows, he understood that it was extremely difficult to refine the "ballista" in his mind.

First of all, it is necessary to make twisted strings and crossbow frames from the muscles and bones of the Heavenly Rank Demon Beast, otherwise it will not be able to withstand the huge elastic shock.

The second is the fine iron arrow shaft, the huge shaft and the strength of the shot, the strength requirements are very high, coupled with the effect of breaking the law and armor, refining a giant crossbow like this is no different from refining a medium and high-end magic weapon, but it can only be counted as a one-time consumable.

In this way, it is difficult to refine and use, and the cost is too expensive, maybe you can refine a ballista to verify the idea, or play with it, but when it comes to the battlefield, the cost-effectiveness ratio is extremely uneconomical.

At this moment, it is not a matter of worrying about the cost and effectiveness of ballistas, first of all, we must block this round of rebel attacks.

Without Gu Zuo's order, Chen Xuanli, who was in charge of guarding the southern city wall, had strictly ordered the monks of Jin Dan and below not to call the crossbow, but instead summoned the five Yuanying monks in the city to be responsible for intercepting them.

However, the puppet Yan rebel lineup launched nearly a hundred ballistas in one go, and no matter how hard the five Yuanying monks tried, they could only intercept a small half.

The rest were either planted in the city walls and used as a staircase for the rebels to ascend the city, or they entered the city, destroying houses and killing and injuring the people, causing a wave of panic in the city.

It is definitely not a way to go on like this, Chen Xuanli, Ge Shuhan, Guo Ziyi, Li Siye, Li Guangbi and other generals all gathered around Gu Zuo, waiting for him to make up his mind.

Gu Zuo still made up his mind: "Inform King Qi and ask him to launch the Vermilion Bird Great Array." ”

The Vermilion Bird Great Array is extremely powerful, but the consumption is also amazing, in fact, this Great Array has already been prepared, and when it is not really activated, it consumes two hundred spirit stones per day to maintain the minimum operation needs. And once it is put into attack and defense, the daily consumption of spirit stones will rise sharply to 1,000 pieces, and it is also the lowest consumption, if you deal with a strong attack, the highest peak consumption will reach 10,000 spirit stones per hour!

If it breaks through 10,000, it means that the big array has been breached.

King Qi got the proclamation, and immediately activated the array on Suzaku Street, and the array of one hundred and eight squares in Chang'an was all activated, and the colorful brilliance shone in the air.

The projection of the Imperial Palace is first reflected in the sky to form the head of the Suzaku, followed by the projection of one hundred and eight Ribo, which conjures up the body and limbs of the Suzaku and even its wings.

King Qi strolled on Suzaku Street, saw the Vermilion Bird that was about to be transformed, waved his left sleeve, and the Western Phantom flew up the head of the bird, turning into a smart eye. The sleeve of his right hand fluttered, and Dongyan turned into Suzaku's right eye.

The eyes were complete, the bird screamed, its wings fluttered, and it shook off the feathers, which seemed to fall slowly, but they were extremely delicately blocked in front of each of the giant crossbows that came to them, turning into pieces of flames, burning extremely quickly, and burning the crossbow body to ashes in a few breaths before the crossbow bolts hit the city walls and swept through the streets.

The Vermilion Bird Great Array blocked the shot of the ballista, but it also consumed thousands of spirit stones in the hour of a pillar of incense, and the intensity of the attack had reached fifty percent of the Vermilion Bird Great Array's extreme endurance!

Although the rebels did not know the limits of the Suzaku Array, they understood the reason for intensifying their attacks and putting continuous pressure on them. An Shouzhong and Cai Xide appeared under the Yanxing Gate, Tian Chengsi mainly attacked the Mingde Gate, Cui Qianyou and Yin Ziqi attacked the Guanghua Gate, and dozens of offensive formations of all sizes shot at the same time, and they attacked Chang'an together.

This was the first full-scale onslaught of the rebels in the siege of the city for more than half a month, and the pressure of the Vermilion Bird Great Array increased suddenly, once reaching the point of consuming seven thousand spirit stones in one hour.

The armies in the city are also desperately trying to relieve the pressure of the Suzaku Array, and everyone knows that as soon as the Great Array is broken, they will face brutal street battles, and the prosperous Chang'an will be destroyed.

Chang'an City was attacked fiercely, and Longshouyuan Dazhai could not be idle, the two sides were very close to each other, and their respective battle conditions and situations were clear at a glance.

Kusang Daoren led the 200 heavy armored cavalry of the Southern Wu Army to attack, and Gao Xianzhi followed with 2,000 headquarters, opened the gate of the wall, and killed it. The rebels were also prepared, and 5,000 people from Shi Siming's department came to rob Longshouyuan Dazhai, and the two sides were immediately killed.

Gu Zuo observed the battles everywhere at the head of the city, whether it was Chang'an or Longshouyuan Dazhai, there was no danger of breaking the city in a short period of time, but he had been waiting at the head of the city, waiting for An Lushan, Dugu Wenshu and Shi Siming to make a move.

King Qi is also waiting for the opportunity to go into battle, no matter who among the three major refining voids comes, he will go up and take the next one. The three lords of the Lishui faction, including the three ladies, plus Tang Thirteen, worked together to deal with one. The last refiner, Gu Zuo's idea was to be resisted by himself, Chen Xuanli, Li Guangbi, and Guo Ziyi.

But if the battle is too fierce, it is very likely that the pressure on the Suzaku Great Array will break through the critical limit, which is what he is most worried about.

There are two solutions, one is to lead the battle with the three major refining voids to the battlefield, and the other is to destroy the enemy's ballistas by surprise before the three major refining voids make a move.

Gu Zuo decided to take the second method, and he was ready to go down in person.
