Li Xian couldn't help but shrink his head as he looked at the huge city defense weapons on the wall, he turned his head to look at Qin Tian and asked, "Boss, the situation is not good! There are so many city defense weapons, if we forcibly attack them, I'm afraid the casualties will be very heavy?"

Yan Qiu glared at Li Xian and said, "Stupid loan, who told you that we are going to attack?"

"Ahh

Qin Tian glanced at Li Xian, then shook his head and said, "Attacking is the stupidest idea, even if we can win in the end, the casualties are unacceptable to us." ”

"Let's test the power of those weapons first, and then decide what to do with them, right?" Yan Qiu said to Qin Tian.

"Well, you go and arrange for some door panels to come over, put them all together, preferably with two wheels underneath, and push them from different directions closer to the smelter and the craftsman. Qin Tian thought about it and said to Yan Qiu.

"Okay, I'll do it right away!" Yan Qiu replied, then turned his head and went to make arrangements.

It didn't take long for several huge and heavy door panels to be erected around the smelter and the craftsman's prison, and the guards in the smelter and the craftsman's prison immediately noticed the situation, and they did not dare to slack off, and immediately operated the city's defense weapons and aimed at these door panels to attack them.

"Boom!" "Boom!"

Huge arrows tore through the night sky and flew in with a loud whistling sound, ready to hit the door panels.

"Bang!" "Bang!"

A dull crash sounded, sawdust flew on the door panel, and the thick two-layer door panel was actually pierced by a blow, and the sharp arrows penetrated the door panel and pierced deep into the ground behind the door panel.

Li Xian lay on the ground and buried his head deeply so as not to be hit by the arrows, and the whistling sound of the arrows was like a life-threatening talisman, which was simply a rubbing injury, and if they touched it, they would die, and no one dared to block their way.

After a few rounds of shooting, the several sets of door panels prepared by Yanqiu were all broken, Li Xian and they had to quickly retreat, and Li Xian was still shocked after coming back, how can that excitement be a cool word.

"There is a gap of about three minutes in one round of firing, but the other side uses the method of group firing, so the effect of continuous arrows is formed. Qin Tian, what do you think about this?" Yan Qiu discussed the results of his observations with Qin Tian.

"Judging from the effect just now, the launch interval of this kind of city defense weapon is really about three minutes, but I also noticed just now that the launch speed of the last few waves is a little slower than at the beginning, which shows that this kind of city defense weapon is not easy to use, and the physical requirements for the operator are very strict, I am afraid that the later they go, the slower their launch speed will be. Qin Tian also said the details of his observations.

"And you mean, a few more rounds?"

"Well, let them find more door panels, and if there are no door panels, a larger one will do. Let's compare with each other to see who can hold on to the end. A smile appeared on the corner of Qin Tian's mouth and said.

"Ah?~~~ Are you going to go?" Li Xian was obviously frightened by the shooting just now, and as soon as he heard that he was going to look for another shot, his face immediately changed and he shouted.

"What's it called, hurry up and get ready!" Yan Qiu wouldn't be polite to this guy, he kicked it over and yelled loudly.

"Boss, can't I go?" Li Xian replied helplessly.

Qin Tian's second wave of temptation was quickly completed, and huge doors or wooden planks were erected again, like a wall of boards, and under the impetus of the soldiers of the pioneer battalion led by Li Xian, they moved towards the direction of the smelter and the craftsman prison little by little.

The expected large arrows struck again, each blow sending sawdust flying from the door panel, and Li Xian and the others could only stick to the ground tightly to prevent the arrows from piercing into meat skewers.

Whenever the arrows stopped firing, they slowly pushed forward, and in this way the door panel continued to move in the direction of the smelter and the master's office.

In the face of the gradually approaching board wall, the garrison captain Cai Yu is very headache, if you don't smash these approaching board walls, then the ambush behind the wall is very likely to attack the factory;

And the enemy also seemed to see the predicament he was facing, and the slab walls erected outside tended to be more and more numerous, and the number of destroys on his side could not keep up with the increase in the number of opponents. And this cunning enemy still roared loudly from time to time, trying to shake his own military spirit with the roar of hundreds of people in unison, which was really hateful.

However, he glanced at his subordinates with worry in their eyes, and had to admire the other party's strategic shrewdness, this kind of heart-attacking tactics did have a certain effect.

Yan Qiu looked very proud, and he asked the soldiers of the Qin team and the iron team to take turns roaring in unison, attacking the garrison of the smelter and the master of the craftsman. Under the continuous roar of the Qin team and the iron team soldiers, the attacks on the opposite side became more and more rapid for a while, but it didn't take long for the frequency of attacks to drop significantly, and it seemed that Yan Qiu's heart attack did play a certain role.

Yan Qiu said triumphantly to Qin Tian: "Qin Tian, how is it, my move is not bad, right?"

Qin Tian nodded and affirmed: "It's really good, we should also put more pressure on the opponent, so that when the final general attack comes, we can reduce casualties as much as possible." ”

"Then do you have any better suggestions?" Yan Qiu asked directly.

"Select some soldiers with more accurate crossbow arrows, form a sniper team, close to the factory under the cover of the board wall, and wait for an opportunity to attack those who operate the city defense weapons, so that they can not operate with peace of mind. Qin Tian thought for a moment and then said.

"Okay, I'll do it!" Yan Qiu also thought it was good when he heard it, and he immediately responded.

While a soldier on the wall was trying to rewind his bed crossbow, suddenly a bolt slid across the night sky, hitting him in the chest with precision, shooting him through the cross, and he looked at the arrow through his chest in disbelief, and then fell straight backwards.

"Be careful, there's a hidden arrow!"

The teammates next to him screamed in shock, and everyone shrank back behind the wall, and it took a long time before they dared to poke their heads out again.

Under the continuous blows of the sniper team, the attack frequency of the city defense weapons on the wall dropped sharply again, and Qin Tian saw that the time was almost up, so he ordered the team to prepare for a general attack.

Just when Qin Tian and the others were constantly testing the strength of the defense of the factory, Cai Yu had to transfer the troops guarding the iron pillar due to the lack of troops, which gave the iron pillar their chance.

As soon as Tie Zhu saw that the garrison outside the courtyard had dropped drastically, and in the end there were only six guards left, he knew that his chance had come. So he immediately expressed his thoughts to his father, and Tie Ye thought about it carefully, and then agreed to his plan.

Now that there is a lot of chaos outside, it is a good time to get out, and if you miss this opportunity, I am afraid that you will not have a chance in the future, so even if it is a little risky, it is worth giving it a try.

The guards in the courtyard were two people at the door and four people in the courtyard, and they formed a semi-arc around the door of the room.

Tie Ye, Tie Zhu, and Tie Dan looked at each other, and then quietly approached the door, and when Tie Ye nodded to Tie Zhu, he kicked the door open.

When the gate kicked open, the iron pillar and the iron egg smashed the chair they were holding in their hands towards the four guards in the courtyard. Although the chair is very heavy, for a person with natural divine power like an iron pillar and an iron egg, it is only the weight of carrying a book.

I saw these two chairs with a whistling sound, and flew towards the four people in the courtyard, which frightened the faces of these four people drastically, and they dodged one after another. And Tie Zhu and Tie Dan had been waiting for this opportunity for a long time, they suddenly increased their speed, and a faint light appeared on the two of them at the same time, and the people pounced on the four people who were waiting to counterattack with the remnants of the Dao.

In the face of the sudden shock, the two guards in front of the door were about to raise their crossbow arrows and attack the iron pillar, but they found that their crossbow handle was firmly grasped by two large hands like iron pincers, and they could not shake it even with their strength.

Before they could make any further moves, the two large pincer-like hands snatched the heavy crossbow from their hands, and then threw them back and slammed them into the head, leaving them unconscious with only a black eye.

When Tie Ye eliminated the two guards in front of the door, the Tie Zhu brothers had already solved the four guards in the courtyard, and in front of the Tie Zhu brothers who used their strength to release their strength, these four guards were too weak to even fight back.

After the three of them looked at each other, they immediately left the courtyard and returned to the smelter.

The smelter is now a time when the people are panicking, the return of the iron smelter has given everyone a backbone, the reputation of the iron smelter in the smelter and the craftsman supervisor is unmatched, everyone basically listens to him, so he ascended to the heights and shouted, and soon organized a team of nearly 500 people to come out, the size of this force is actually more than the number of garrison troops.

The two brothers did not follow their father, but went straight to the house where their mother was being held. This is my father's residence, and the guards are usually very tight, but today there are only two guards here, it seems that the war outside is really critical, and Cai Yu can't arrange too many people to take care of it.

The two guards were naturally not the opponents of the Iron Pillar Brothers, and they were easily pinched to death by the Iron Pillar Brothers. The Iron Pillar brothers, who rescued their mother, immediately rushed to join their father, Tie Ye, and their shackles were quickly removed by his father using a lock-picking tool.

It may be very difficult for ordinary people to remove such shackles, but for the master of the weapon, it is only a trivial matter.

As soon as Tieye's team had finished gathering, they heard a sonorous roar in the distance, and everyone looked at each other in confusion.

But Tie Zhu suddenly grinned and said to his father: "Dad, it's Qin Tian and them." They've come to our rescue!"

"Oh, are they really?" asked Tie Ye, a little surprised.

"There's no mistake, I can't be wrong with their voices. Tie Zhu must have said.

"There are many powerful city defense weapons on the walls on all sides, Qin Tian and they may be very difficult to attack head-on, we must immediately set off and attack Cai Yu's garrison from behind, creating an opportunity for Qin Tian and them to attack. "After all, Tieye is a person from the past, and he still has a very correct grasp of the key to the problem.

"Then let's hurry up!" Tie Zhu was also anxious when he heard this, and he hurriedly urged.

"Well, everyone hurry to the warehouse and move all the weapons and armor out, we will immediately arm ourselves, and then kill Cai's troops!" Tie Ye nodded, then turned to his troops and said.

"Kill them!"

"Kill them!"

Everyone roared angrily, after all, almost all the people in the factory were arrested by the Cai family, and they all had a blood feud with the Cai family, how could they not make their blood boil when they had a chance to take revenge at this time?
