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 force them to attack, 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, "Assault is the stupidest attention, even if we can win in the end, 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 and put them together, preferably with two wheels underneath, and then get them closer to the smelter and the smithy from different directions. 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 artifact factory, and the guards inside the smelter and the artifact factory immediately discovered the situation, and they did not dare to slack off, they immediately operated the city defense weapons, aimed at these door panels and launched an attack on 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 arrow 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-urging talisman.

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

"There is a gap of about three minutes between one round of firing, but the other side also uses the method of group firing, so the effect of continuous arrows is formed. Qin Tian, what do you think?" 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 just noticed 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 when 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 a huge door or wooden board was erected again, and Li Xian led the soldiers of the pioneer battalion to lie behind the door panel, and pushed it in the direction of the smelter and the craftsman prison little by little.

The expected large arrows struck again, and each blow sent sawdust flying all over the door panel, and Li Xian and the others could only stick to the ground tightly to prevent them from becoming flesh.

As soon as the arrows stopped firing, they slowly pushed forward, and in this way the door panel moved 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 has a headache, if you don't smash these step by step board wall, then the ambush behind the wall is very likely to attack the factory;

And the enemy on the opposite side also seemed to see the predicament he was facing, the slab walls erected outside had more and more tendencies, and the number of destroyed 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 the morale of his army by roaring in unison of hundreds of people, which was really hateful.

However, he glanced at the worried eyes of his subordinates, and had to admire the other party's strategy, this kind of heart-attacking tactics did play a certain role at this time.

Yan Qiu proudly let the soldiers of the Qin team and the iron team take turns to roar in unison, and fought a heart-to-heart battle against 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.

It seems that Yan Qiu's heart attack did play a certain role, and Yan Qiu said triumphantly to Qin Tian: "How about Qin Tian, my move is not bad, right?"

Qin Tian nodded and affirmed: "It's really good, we should also add more pressure to 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.

As a soldier on the wall was trying to rewind his bed crossbow, a bolt slid across the night sky, hitting him in the chest and piercing him, and he stared in disbelief at the arrow that passed through his chest, and then fell straight back.

"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 significantly, and in the end there were only six guards left, and he knew that his chance had come. So he expressed his idea to his father, and Tie Ye thought about it seriously and agreed to his plan.

It's a mess out there right now, and it's a good time to get out, and if you miss this opportunity, I'm afraid you won't have a chance in the future, so even if it's a little risky, you have to give it a try.

The guards in the courtyard were two at the door and four in the courtyard, and they surrounded the room in a semi-arc. Tie Ye, Tie Zhu, and Tie Dan looked at each other, and then approached the door together, and when Tie Ye nodded to Tie Zhu, he kicked the door open.

After kicking the gate 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 four people's faces and dodged one after another. And Tie Zhu and Tie Dan had been waiting for this opportunity for a long time, their speed suddenly soared, 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 to the iron pillar and they found an attack, but they sent out their crossbow handles and were firmly grasped by two large iron pincer-like hands, and they could not shake it even with their strength. Before they could make any further movements, the two large pincer-like hands snatched the heavy crossbow from their hands, and then slammed them into their heads with a flick of their hands, and they lost consciousness as soon as their eyes darkened.

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

The three of Tieye's father and son glanced at each other, and immediately left the courtyard. The smelter is now a time when people are panicking, the return of iron smelting has given everyone a backbone, iron smelter's reputation in the smelter and the craftsman supervisor is unmatched, everyone basically listens to him, so he quickly organized a team of nearly 500 people out, the size of this force is actually more than the number of garrison troops.

The two brothers did not follow their father to organize the troops, and as soon as they came out of the courtyard, they rushed to the house where their mother was being held, which was their father's residence and was very heavily guarded. But today, there are only two guards here, and it seems that the battle outside is indeed very 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 Tiezhu brothers, who rescued their mother, immediately rushed to join their father Tieye, and the shackles on their bodies were quickly removed by their father using a lock-picking tool, which may be very difficult for ordinary people, but for Tieye, the master of the weapon, it is just 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 wall, Qin Tian and their frontal attack will probably be very difficult, we must set off immediately to attack Cai Yu's garrison from behind, and create an opportunity for Qin Tian and their 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?
