Things went surprisingly well, and with the help of the redeemer who had opened the gates, the humans were able to storm the inner city of the defensive line in less than one morning.

Su Ming looked at the nearby terrain, there were drawbridges on both sides of the high-walled passages, and if the humans attacked it, the aliens would burn the planks of the drawbridge.

The door below was a solid iron door, and when he closed the door, Su Ming saw that the thickness of the door panel was close to half a meter. From time to time, the alien head above poked his head out to look at the situation below, and it was impossible to sneak attack.

"Commander, are we still going to attack?"

"No need, just camp outside the city and let the soldiers rest for a while." Pulstic said that the iron wall in front of him could be breached, and even if it could not be breached, dragging the aliens inside could prevent them from interfering with the excavation of the crystals.

Su Ming wiped the blood stains on the sword and put it in his backpack, this siege battle was fought too smoothly, so smooth that it was a little unreal. And the number of enemies inside does not seem to be as large as expected.

Su Ming faintly felt that something was wrong, but he couldn't confirm it.

At noon, a redeemer tried to put a corpse on the ground and approached the iron gate, but when he was spotted by the aliens on the wall, the arrow rain almost shot him into a porcupine. If it weren't for his attribute being Tan and a shield, I'm afraid he would have been killed by his own sassy thoughts.

The generals didn't stop the attempt of this group of redeemers, what if they opened this door again?

"Boom!" A rocket exploded in front of the iron gate, with a deafening roar. When the smoke cleared, the iron door was still strong, and the aliens on the wall breathed a sigh of relief, their legs trembling when they heard the explosion.

Do you continue to rely on the cloud ladder to attack, Su Ming shook his head, it was sent to death. The siege engines were too big to enter through the outer gates. It is too cumbersome to reassemble and assemble in the city, these are siege engines built in the fortress, and the soldiers may not be able to install them after dismantling them.

Is it just waiting for the mission to end? Su Ming was a little unwilling.

"Didn't the large army of aliens hide in it and didn't come out?" Su Ming found Stud King and asked.

"I don't know, maybe we'll see it in another fight."

……

After looking at the iron gate in the distance, Su Ming made up his mind that he wanted to discuss with the redeemers.

"I'm interested in having a big vote?" Su Ming found a team and asked.

"Tell me about it." The leader of the team was a middle-aged man in his thirties, who was white and chubby.

"Blow open the iron door."

"Poof!"

"I thought it was a good idea, you don't think we thought about it? Don't think you're smart. A graceful woman in the middle-aged group smiled.

"Brother, let's not talk about whether you can rush through, that door is half a meter thick and what kind of bomb can be used to blow it open?" The fat team leader also smiled.

"The door is made of iron, yes, but the city wall is not, the door frame connecting the iron gate and the city wall must be very fragile, we just need to put a lot of explosives into that pile, boom." Su Ming's hand made an explosive gesture.

Su Ming's words reminded everyone, that's right, they don't need to blow up the door, just knock it down! The brother who blew the outer door open only knocked one door down.

"But where did we get the big bombs? Less explosives are not necessarily useful. The woman asked.

"So we need everyone to come together, there are hundreds of redeemers who come together, how can we make it together." Su Ming said.

Su Ming's suggestion made this group of people tempted, if the battle situation is deadlocked, there are only two possibilities: the first is to withdraw the army, and the second is to attack. From the perspective of alien defenses, the probability of a successful assault is very low, and hundreds of thousands of soldiers may have to die to succeed.

I don't know if there will be a shortage of manpower to let the redeemers participate in the siege together, no matter what the result is, everyone is unwilling to accept it, there is no oil and water to leave, and the siege is too dangerous.

Blast open the door and then kill it is the best option.

"Okay, if the other teams are willing to do it!" The fat leader is very prestigious, and no one in the team refutes him.

Next, Su Ming and them found several other teams, and after explaining the situation, these people expressed their willingness to assist in firepower, and many people carried bombs, so they might use them at any time.

After putting together enough bombs in the hands of a bunch of redeemers, Su Ming fell into a dilemma, the amount of explosives was definitely enough, but who would plant them? Explosives are particular about this thing, and it's not just a matter of throwing a bomb at random.

"Look for that kid in the morning! He's a professional for sure! "There was a man who reminded Su Ming, yes! If you have a specialization in the art industry, you should find a professional for this kind of thing.

"I think I saw the brother just now, he seems to have been invited by some soldiers on the other side of the outer wall." There is a personal reminder.

"Go find him."

A group of people ran out of the wall in high spirits, and the breaking down of the door might have to fall on him.

The brother was sitting on a pile of rubble when the crowd found him, and he broke out in a cold sweat when he saw a group of people surrounding him.

"Brothers, you have something to say! I don't think someone in Zhou has done anything wrong to you, right? This is a twenty-five or sixteen-year-old man, with a pair of glasses and a plain look, and he hurriedly got up from the stone and said.

"Brother, don't be afraid. I'm looking for your help! The fat team leader said to him with a smile.

"Please...... Please speak. ”

"You must know how to blast when you opened that door in the morning, right?" The fat team leader asked.

"Understood...... Understand! I used to make bombs, and then I did engineering blasting. This Brother Zhou saw that everyone had something to discuss, and his heartbeat stabilized.

"We have a plan, it's like this......" The fat team leader said Su Ming's thoughts.

"How much explosives do you have?"

Su Ming took out a bunch of explosives from his backpack, and Brother Zhou hurriedly took a few steps back when he saw this number of bombs.

"Enough is enough!"

"The dose of explosives is fine, the question is how do we get close there? I will set up bombs, but the archers and mages will not open their eyes to me. Brother Zhou voiced his doubts.

"Don't worry, when the army covers, we will arrange for Tan to protect you and send you to the door properly." Su Ming's explanation put him at ease, and he thought for a while and agreed.

"Yes, I'll take it."

"Can the Legion listen to you? In case they don't believe us......" The fat leader was still a little skeptical.

"Don't worry, I'm very familiar with Stood King of Unit 2, and I will do it if I say yes." Su Ming's words were sonorous and powerful, which made people dispel suspicions.

"Okay, then we need everyone's cooperation, this matter is related to the benefit of all of us, I hope to make a strong contribution and can help."

"Tan must help, he can't bear the rain of arrows without a shield."

"Fire support from a distance, kill archers and mages as much as possible."

"Well, it's easy." A strong man said while holding a one-man heavy sniper.

Everyone, you and I will arrange the plan in a word, and it will be up to us to see if the next day will be as people wish.

"Then it's decided, Tan is responsible for protecting the demolition ghosts, long-range fire support, nurses are responsible for healing, and melee combat is in case of accidents." Everyone had no opinion on the fat leader's words.

"Brother, it's up to you to get in touch with the Legion next."

Su Ming smiled and didn't speak, turned around and walked towards the barracks outside.

The barracks outside are an open-air field made up of improvised pot stoves, and soldiers are fishing for food around iron pots.

"Wait, I'm with you." Zhao Wen chased after him from the rear, and he was very curious about how Su Ming persuaded Stode Jin to attack the city.

He was wiping his saber when the two found Stud King, and when he saw Su Ming and Zhao Wen, he withdrew his sword from its scabbard.

"What's wrong with you?"

"General, we have a way to break through the iron gate." Su Ming said.

"Oh! Tell me about it! "Stud King is interested, and if he captures De Phct, it will definitely be a great victory for the Empire.

"I have a fellow villager, the brother who blew up the outer gate in the morning, his family inherited a secret technique that can make some things explode after combination, we decided to blow up the iron gate to open the way for the army, and then the soldiers can attack the inner city with only a small loss."

"But we need the army to attack the city in advance to cover, otherwise we won't be able to withstand the magicians and archers."

"Oh, it turned out to be him. No wonder ......"

"General, have you looked for him?" Zhao Wen asked.

"Yes, we want to learn this technique from him, but we don't understand what he says, we don't know what explosives, fuses, or timers are." Stud King said.

"If you had known that the alien race would have been over a long time ago......" Zhao Wen muttered in his heart.

"General, can you let the commander think about it?" Su Ming looked at the decisive Stud King and said.

"Is this a sure thing? You also know that the real purpose of the commander's attack on the defense line is to prevent the aliens from finding crystals, and crystals are our main goal. ”

"It's true that crystals are important, but capturing this line of defense is also a feat, so why not kill two birds with one stone?" Su Ming's words tickled Stud King's heart.

"Are you sure he can do it?"

"Yes! My fellow countryman promised with his life that if he failed, you would cut him down. Su Ming's words reassured Stud King.

Zhao Wen turned his head and glanced at Su Ming seriously, the brother surnamed Zhou definitely didn't say this.

"Good! Another warrior who dares to dedicate himself, talent! Talent! I'm going to talk to the commander-in-chief! King rubbed his hands excitedly.

Seeing the back of his departure, Su Ming knew that this was done.

"Did you use MLM before?" Zhao Wen looked at the departing Stode Kim expressionlessly and said.

"It's not ......"

After Su Ming returned to the group of redeemers, he said that everything was fine, and then it was up to Brother Zhou to play.

"The iron door uses a hinge-shaped door frame, so that the inlay can be stable, we just need to make a blast hole in the connection between the rock and the door frame, and put the bomb in to detonate it."

"It's better to put it on both sides, so it's safe." Brother Zhou pushed his glasses and said his plan.
