Da-da-da-da.

Alan tapped lightly on the stone face, thinking about how to fight in the coming days.

Yesterday alone, Tomorrow City consumed tens of thousands of bullets.

If the next war continues with the consumption of the first day, it will only take two days, and Tomorrow City will fall into a dumb situation because of the lack of ammunition.

The situation is very unfriendly.

Alan didn't like to fight such a poor war, and he set a strategic policy from the beginning, and he wanted to use the savings plan to win the war.

Because of his injury, Ivan is now patrolling next to Allen, and by the way, let's see what good plans Allen has.

He saw Alan frowning and thinking hard, as a subordinate, he naturally had to help the commander share some of the pressure.

So Ivan thought about it and suggested:

"Lord Allen, those eagles are so obedient, and the eagle intelligence courier system is also mature, it is better to let the eagles carry a special token and put it on the enemy's side to deal a devastating blow to them."

Ivan stretched out his fist, opened it quickly, and the onomatopoeia of "boom" came out of his mouth.

"What token?" Alan was still thinking about the plan and subconsciously responded to Ivan.

Ivan looked at the floor drawings on the stone face, pointed to the location of Sun City, and then pointed to the current location of the Lionheart army, and said, "The token is an explosive bag, how about it?" ”

Hearing this suggestion, Eren looked at Ivan in surprise.

Ivan was embarrassed, he saw Allen's surprised little expression for the first time, and it seemed that he had made a very good suggestion.

However, Allen's next sentence made him break out in a cold sweat:

"Ivan, do you want to go to heaven?"

Heaven?

He doesn't want to go to heaven, and if he does, he won't be able to come back.

Ivan quickly shook his head, shaking like a rattle.

"But explosives packs are dangerous, and when you use eagles to transport explosives packs, you have to consider the possibility of sudden explosions, after all, explosives packets can become explosives when they are inserted into a detonator." Alan shook his head.

After listening to Alan's explanation, Ivan wiped the cold sweat from his forehead, no wonder he wanted to go to heaven.

It is well known that nitroglycerin becomes very stable when mixed with diatomaceous earth, and it does not explode even when explosives are fired with a gun.

The initiating charge in the detonator, mercury thunderate, is very sensitive, and a slight rubbing out of gunpowder or collision will cause an explosion.

If the detonator has been inserted into the explosive, the mercury thunderate will detonate the explosive after exploding, and the eagle will die in vain.

The Eagle obviously does not have such maneuverability, and the conditions for the invention of a time bomb have not yet been invented in this era, Ivan's idea can only be described as a bit fanciful.

"But your idea is good, in the future, with transport planes such as hot air balloons or airplanes, your bombing strategy will definitely succeed." Alan patted Ivan on the shoulder, approving of his idea.

"Yes!" Ivan's heart was hot, and he hesitated: "But no one is going to make hot air balloons now." ”

He didn't ask how to build the plane, the textbook mentioned the function of the plane, it was a very complex and elaborate large machine, and Tomorrow City was not capable of making that thing at the moment.

Compared with airplanes, it is now a little more practical and easier to build trains.

"It's not difficult to make a hot air balloon, as long as the chemical laboratory makes a high-pressure gas tank to collect hydrogen, and then gets an ignition device, a wooden box woven of rattan, a cowhide balloon woven with needle and thread, etc." Alan said casually.

"It doesn't seem to take long, the chemistry lab has the experience of making high-pressure hydrogen tanks, and you only need to sew balloon skins from the weavers." Ivan walked back and forth, and the more he thought about it, the more he felt that the plan made sense.

"Then you can implement it, use carrier pigeons to send messages, and do it as soon as possible."

"Okay."

Ivan got Alan's approval, and felt that the whole person was floating a lot, and ran to blow the whistle and write a letter to the orcs in the downtown area of Tomorrow City.

While waiting, the eagle and the pigeon came to Allen again.

They used bird language to describe the appearance of the stronghold they saw in the sky, and according to their description of bird language, Alan used his hand-drawn ability to draw the building distribution of the enemy's food hoarding stronghold.

Due to the birds' limited vocabulary and the fact that they are not highly intelligent animals themselves, and unable to describe the complex distribution in simple words, it took Alan nearly an hour to map the enemy's new stronghold.

"The map of the building distribution of the stronghold is available, and only the people in the city need to deliver the hot air balloons. By the way, Lord Alan, why don't you try to teach the pigeon and the eagle, maybe they can cooperate in the bombing mission of the explosive pack. Ivan looked at the two birds expectantly.

He was the man who squatted next to him and watched Allen's map the whole time, and Allen used a lot of bird language to communicate with two birds and animals, which made Ivan think that an eagle and a pigeon were the most intelligent beings of the same kind, and there was a possibility of being taught to be a weapon of war.

"I'll give it a try." Alan ordered a sandbag to be brought over, and a thin piece of wood.

Anyway, it's boring, the enemy is too far away, Alan doesn't want to move his troops to fight so far, and it's even more impossible to fight with rifled guns, so tease these two birds and prepare with both hands.

The eagle has a decent IQ and learns quickly.

An eagle chirp sounded, the eagle talons grabbed the rope of the sandbag, transported it to the established point, loosened the sandbag rope, and the sandbag made a resistive falling movement in the air, and successfully fell into the approximate drop area.

However, once the wind direction increases, the eagle's chance of hitting the target is low, after all, its IQ is not enough to calculate the falling motion involving various forces.

The IQ of this pigeon in front of him is also a fluke in its kind, and after half an hour of special training, it can perfectly complete Allen's instructions.

The pigeon is very skilled in sticking a wooden stick into a sandbag, but the detonator is not a wooden root, it has strict requirements for transportation, and a violent collision will detonate the detonator.

By the way, Tomorrow City is developing a fire detonator, and you don't need to make a fire to ignite the fuse to ignite it, you only need to pull the pull rope, and the iron rod connected to the pull rope will pull the fuse and rub it against the iron rod to make a fire, and the next time the fuse burns is the explosion countdown.

"Seems like it's doable." Ivan sat next to him, looking at the two birds, his eyes shining.

The eagle and the pigeon shook their wings, feeling very uncomfortable, and always felt that Ivan wanted to stew them.

"Why don't you give the pigeon a detonator and let it be transported?" Ivan looked at the pigeon with a burning gaze, which made the pigeon feel more nervous.

The pigeon took two steps, twisted its head up and down, and tried to glare at Ivan with fierce eyes, not knowing what the task was next.

After a while, the detonator was sent to the flat ground by the orcs who were specially responsible for transport.

"Come on, this is a detonator, use it like you just trained the stick." Alan grunted a few times and asked the pigeon to take a test flight with a small detonator.

The pigeon took over the detonator and examined it carefully with his eyes.

The shape of the detonator is on the small side, and the pigeon's talons can barely hold it, but it is not easy to grasp when flying.

It is more powerful than a large firecracker, and if you hold it in your hand, you can hurt your fingers.

The first time I held a detonator for a test flight, the pigeon fluttered and fluttered into the sky, and the small detonator accidentally slipped out of its paws and fell to the ground.

"Boom!"

There was a miniature explosion at the landing point, and no small pit was blown up, but the sound was very loud.

This frightened the pigeon, and it turned out that the owner wanted to teach it how to transport such a dangerous thing.

The detonator is also distinguished by power, and the detonator in the pigeon's hand is the least powerful detonator, and Alan thinks it is not a big deal.

But this pigeon is different, its IQ is a fluke among its kind, and it feels that its life is in danger.

After witnessing the explosion of the detonator landing, the pigeon flew to Alan's shoulder and muttered to Alan.

"Goo-goo!"

The pigeon said it was tired and needed to go back and rest.

Alan agreed, let it go back for two hours, and come back to it two hours later.

"Goo-goo!" The pigeon nodded its head in a sign that it would not be seen or dispersed.

The pigeon then spreads its wings and glides into the forest.

Then there was no then, Alan and Ivan started waiting for the pigeons after two hours, and waited for a long time, not waiting for the pigeons to come back.

"Strange, why hasn't the pigeon come back?"

"The sun is setting."

"Yes, it's dinner time again, and the pigeons haven't come yet."

waited until the sun went down, and the two suddenly woke up-

That pigeon, it's a pigeon!
