Dai Tian put down his heart at this time, it doesn't matter if he loses face in front of Duo'er, if Lu Jie'er knows, he really can't mix in the circle.

But as soon as he put his heart down, he suddenly heard the cries of Lu Jie'er and others outside the door: "Dai Tian, what's wrong with you, is something wrong?"

It turned out that Lu Jie'er and the others saw Dai Tian suddenly run away in a panic, and they guessed together for a long time, but they didn't guess the fame, and they were worried about whether Dai Tian was injured internally, so they came over to ask.

When Dai Tian heard it in the room, he was so nervous that he panicked, and he opened his mouth to agree, but when he thought of his voice at this time, he quickly stopped, how can he say such a sissy's voice.

"Why didn't Dai Tian react, did he faint, we need to break in. Lu Qi's voice came from outside the door.

Dai Tian became even more nervous, and in the chaos, he had to regard Duo'er as a savior, and gestured tightly to Duo'er with both hands like twisted flowers.

Fortunately, Duo'er was smart, and was compared by Dai Tian several times, and finally understood, and asked in a low voice: "Are you asking me to tell them that you are researching and designing a crossbow machine, right?"

Dai Tian nodded repeatedly.

Duo'er said in a loud voice to the door: "Dai Tian's benefactor is designing a crossbow machine and preparing to fight the Demon House with a crossbow. Don't let him bother!"

Outside, Lu Jie'er and the others heard it, and then they were relieved, because they planned all the way and went to steal guns, just to assassinate the Demon House, since Dai Tian was busy with this matter, he didn't understand this aspect, and it was a delay to go, so he left and returned to the original room.

Hearing the footsteps outside the door, Dai Tiancai in the room was relieved, breathed a few sighs of relief, and said to Duo'er again and again: "Thank you Sister Duo'er for breaking the siege!"

Even Duo'er laughed, because his benefactor's appearance was too funny, a very strong young man, he had to speak in this tone, coupled with that charming and moving expression, which really made Duo'er can't stop watching.

"Don't make fun of me, I don't have the habit of being a pseudo-mother, don't get me wrong, there is a reason for it......" Dai Tian explained again and again.

Duo'er said: "How could Duo'er make fun of the benefactor, but the benefactor is so cute." As he spoke, he couldn't hold his mouth and laughed again.

Dai Tian just complained in his heart, and when he wanted to explain, he was afraid that it would be difficult to explain it for a while, so he had to endure it in his heart.

Since they lied to Lu Jie'er that they wanted to make crossbows, they naturally couldn't be without results, and one day has passed since the original three-day period, and there are still two days left to meet the day of the Great Demon, and the crossbow machines for twelve houses will be arranged and made in two days, and the time is already urgent.

Therefore, Dai Tian just took a short rest, checked the situation in the room again, and then kept busy in the room.

Tear down all the screens, tables and chairs in the room, dismantle them into large and small horizontal logs, columns and braces, tear the sheets and tents, and roll them into ropes.

Looking at the messy room, Duo'er was puzzled, and asked tentatively, "What is the benefactor going to do?"

"Make a crossbow machine, there are no other materials in this room, and I have to dismantle these!" replied Dai Tianxi.

"Can Do'er help her benefactor?"

Hearing this, Dai Tian looked over suspiciously.

Duo'er naturally saw the meaning of the benefactor, so she said: "Don't worry, although Duo'er is a rat body, because there are human finger nerves on the rat's paws, although some are stupid, but they can also complete some inferior actions, and after I demonize, my body is radicalized and has great strength." ”

Looking at her earnest expression, Dai Tian couldn't refuse, and nodded in agreement at that time.

Duo'er was naturally overjoyed, jumped into the middle of the scattered wooden supports that had been removed: "The benefactor just sits there and orders, and Duo'er will do everything for you." ”

The bow and crossbow made by Dai Tian only talk about practicality, not about appearance, Duo'er can help, but it can also save him some effort, so he is not polite, and commanded Duo'er: "Tie these two big pillars to the beams of the house!"

Thanks to Duo'er, not only has great strength, but also can jump, pick up the column, only one jump, and then arrive at the beam, and use a cloth rope to tie it to the beam, one on each side.

"Fix these two shorter beams behind the beams. ”

Doll did what she said.

"Tie those two beams on the other and twist them more than a dozen times!"

"The thinnest rope is used as a crossbow string and fixed between two beams. ”

"Make it on the back wall to fix it, and use it as a string base!"

......

Dai Tian continued to give instructions to Duo'er, Duo'er was not only well-behaved, but also powerful, basically did not let Dai Tian do it, just a delicate place.

A rat and a person are busy, between the two beams, it is made into a huge crossbow bed, look up to see the crossbow bed, only to see: with the beam as the crossbow bed, enough to have a zhang wide, with the screen column as the arm, twisted countless circles, plus a small brace and a horizontal wood, tension potential energy, twisted on the crossbow string, and fixed the hanging knife bracket on the wall, the whole crossbow elevation angle upward, enough to shoot the sky, the trend of collapsing the mountain.

Dai Tian looked up and pondered: "Such twelve rooms can make twelve crossbows, if they are fired at one time, they can only shoot twelve crossbow guns, the number is too small, but the crossbow is small, and it can't reach the power, we need to make a continuous bead crossbow, and we twelve people must escape before the crossbow is fired, and we must achieve the purpose of automatic firing, so we must make automatic bead crossbows." ”

After some design, Dai Tian commanded Duo'er again: "In the crossbow bed, stick to make a crossbow, and then fix a winch on the suspension knife......"

Under his command one by one, the original huge crossbow bed was improved and made into an automatic bead crossbow.

Dai Tian commanded Do'er to test it.

Let Doer turn the winch first, fix it on the bracket, and wrap several loops of rope on the bracket, because the winch uses a thick rope to increase the potential, so it slowly breaks free from the thin rope on the bracket, and suddenly all of them break free, and the winch rotates violently at high speed.

"Bang ......" As the phoenix wings on the winch stirred the crossbow string, the crossbow string was pulled back and pushed forward, dozens of times in a row, and the sound continued.

Listening to the sound of the bowstring, Dai Tian nodded with satisfaction: "This strength should be no problem! “

Duo'er stood at the bottom and looked up, although the crossbow was rough, but the sky-swallowing momentum and clever design made Duo'er surprised, and she admired this benefactor again and again in her heart.

Lian Shi, when he looked up at the outside of the room, it was already past noon, and after all these time delays, the feminine inertia on Dai Tian's body had subsided, and he opened the door and walked out.

The corridor had just stood still, but more than a dozen people rushed over and shouted, "Is it designed, let's see." ”

Hearing this, Dai Tian's heart trembled, it turned out that they were all eavesdropping outdoors, did they hear their own voice commanding Duo'er?

When Dai Tian was worried, Lu Jie'er came to him and said to him with concern: "It turns out that you haven't slept all the time, so big two dark circles." ”

Dai Tian didn't answer her, but asked, "How do you know that I'm out?"

"We were waiting impatiently in the next room, and when we heard the door opening, why didn't we rush over. ”

When Dai Tian heard it, he was relieved.

More than a dozen people poured into Dai Tian'aba together, and as soon as they entered the door, they were startled, because they saw that the room was full of empty space, except for the half-drawn bed, there was no other furniture, and there were only some scattered and unused small supports on the ground.

"Wow, wow!" Lu Zheng and Lu Ben suddenly looked up and saw the big crossbow in the middle of the beam, so they exclaimed.

When the others looked up, they were all amazed, some of them had seen Dai Tian's improved crossbow machine on the city wall before, but it was only temporary, and the design and size of the self could not be compared with this one, how could they not be amazed.

Lu Qi said: "With such a big crossbow, plus those guns, I'm afraid the entire house of the Demon House can shoot through!"

Lu Qi said this, it was not an exaggeration at all, because they had grown so big, they had never seen such a big crossbow bed, and the stolen gun was also made of the bones of fourth- and fifth-order demonic beasts, if it could be fired successfully, it would not be an exaggeration to pass through the wall and through the house.

"That's right, and it's twelve rooms, it's twelve big crossbows, and they are fired together, this power is strange if you don't stun Dongzhiren's eyes. Lu Zheng also followed.

"It's just a pity for the inn furniture. When Lu Qi quipped, he laughed.

"It's our enemy, what's the pity. ”

Listening to what they said, Dai Tian was proud for a while, and secretly thought: "I have been studying firecracker pipes for some time, and I finally have some achievements, so it is better to use the bamboo pipe this time, although the explosion power is a little weak, but the sound is terrifying, and the explosion ignites a fire, which also makes Dongzhi people panic." ”

While thinking like this, he asked Lu Jie'er for the Heaven Swallowing Wrap again, because his bamboo pipes, stone nitrate and other materials were all in the Heaven Swallowing Wrap.

Open the Heaven-Swallowing Wrap, first take out the future spear, put it in the corner of the door, and say to a few people: "You are familiar with this crossbow first, and the other eleven rooms are also copied in this way." ”

The others responded and stood on the ground and looked up carefully.

Dai Tian picked up the Swallowing Wrap and came to another quiet room, there is a room in the room, and there is naturally no shortage of quiet places.

Dai Tian was busy again, using the materials he brought, to make a hundred and ten arm-long explosive bamboo pipes. They were busy until it was getting dark, and the others were fully familiar with the crossbow.

Originally, everyone wanted to make a crossbow machine overnight, but they were afraid that the ringing in the middle of the night would make the innkeeper hear the suspicion, so they had to go to bed early.

The next day, everyone got up early, had breakfast, and began to close the door and go busy, first dismantling the wooden furniture of the twelve rooms, and then imitating Dai Tian's crossbow machine to make it.

Because the space of the twelve houses in this row is the same size, and the furniture in each room is also the same, the other eleven houses can be copied without much trouble.
