Alan came to the barracks, mainly to get guns, and seeing that the orcs were queuing up to get guns, he took over the military power by the way and took the first batch of troops with guns out of the camp.

"All of you move forward!"

Eren shouted loudly, and all the orcs with guns on their backs lined up in four rows, running forward quickly and neatly, running out of the camp.

At this time, the gate of the camp was crowded with people, and ordinary orcs with various beast ears stood and crowded outside the camp, both excited and nervous.

"Come on!"

"Blow the beastmaster's head!"

"Lord Alan!"

The shouts came one after another, and the soldiers who went out were still a little nervous before the battle, but after hearing that everyone was so enthusiastic, they were also infected and full of enthusiasm.

"Da Da Da-"

The orcs walked in a neat stride towards the outside of the camp.

The orcs at the gate of the camp automatically gave way to a reason for people to pass, and the road was full of orcs who couldn't sleep and came out to see them off.

Some orcs dragged their families and watched their men and women go on the expedition.

Alan was naturally in the queue, two rows on the left and two rows on the right, and he was sandwiched in the middle to prevent being swallowed up by the enthusiastic people.

As the army continued to move forward, there were far fewer orcs to see off along the way.

Then came the faces of the orcs in the administration building, all of whom were a little worried, worried about whether the multi-race beast tide would succeed in storming Tomorrow City.

"Brother Allen, come on!"

Two cat-eared Loli suddenly appeared in the crowd, it was Efeena and the two, the school bully, the little teacher.

Standing next to them was the Minister of Education, Hoss, who stood up and saluted the whole army.

Alan's serious expression melted slightly, and he nodded to them with a smile.

Then the army went all the way to the main wall, like a green stream in the night.

After a twenty-minute trot, Alan led the team to the walls of Tomorrow City.

"Lord Allen, now the beast tide has come to a place more than five thousand meters away from the city wall." Ivan's expression was solemn and he reported the information about the incident.

The night was supposed to be the time to sleep, but the soldiers were not affected, and the long-term military training allowed them to develop a state of being ready to fight at any time.

"Well, you take two hundred people to guide the beast tide, try to guide to the side of the main city wall, if you can't, forget it." Alan immediately arranged a drainage plan according to the current situation.

There are walls throughout the city, but the height of the walls varies, the main wall is ten meters high, and the rest of the city wall is only more than four meters high.

In terms of safety, it is certainly a ten-meter wall that gives more confidence, while a four-meter wall does not build confidence.

However, Tomorrow City is not vegetarian here, and the weapons are always being updated.

In addition to muskets, artillery, and the new yellow powder from the chemical laboratory, nitroglycerin, which was a real explosive, not the soft attack power of black powder.

If black powder needs an aerobic environment to burn, then yellow explosives are powerful, and it can perform detonation work in a zero oxygen supply environment.

In order to ensure the safety of transportation, nitroglycerin is very safe after being adsorbed by diatomaceous earth, but it needs to be matched with a detonator, and mercury thunderate is required to make a detonator.

First, mercury and nitric acid react to form mercury nitrate, and then micro-heat with ethanol and other steps.

With mercury thunderate, the next step is the production of nitroglycerin, needless to say about the detailed production process, with Allen's full-level teaching, the orc apprentices who learned chemistry did not find it difficult to operate.

It's just that there are not many mercury mines in the local area, which restricts the development of Tomorrow City, otherwise Tomorrow City's weapons can be developed to rear-loading rifled guns, instead of still researching front-loading rifled guns.

The fat man can't eat it in one bite, and Alan is not in a hurry, as long as there is a city wall, he can use the animal's eyeliner to observe the situation and make maximum support adjustments.

"Lord Allen, the yellow powder carried by the orcs in the barracks has arrived, how to distribute it?"

Another orc walked up the wall and excitedly reported the incident.

Since the invention of yellow powder, Allen has not found a target to test the explosion.

None of the orcs who made the explosives knew whether their products were made or not, and only Alan himself could check the quality of the finished yellow powder through identification.

The answer is naturally above the qualified products, and after Allen completed the identification, he ordered someone to seal it, and also sent two orcs to guard the arms warehouse, and attached great importance to yellow powder.

"Let the assassins bring two explosives packs, if you see a dense herd of beasts, you can try to throw the explosives packs, if you don't have a chance, forget it, by the way, if the explosives are thrown close to explode, you must use the black shadow to dodge a round of explosion shockwaves, otherwise your lives will be in danger."

Alan emphasized the danger of explosives, which were terrifying, and the shockwaves at close range were enough to pose a great threat to the orcs.

These dangers had been taught in the previous use of black powder, and the orcs naturally did not joke with their lives, and after receiving the order, they took the explosives bag in their hands very seriously.

After a while, Natasha, the deputy military minister, also received a bag of explosives and fire detonators.

"Lord Allen, how strong is this explosives pack?" Natasha had a question.

The explosives bag is not large, the size of the face plate, flattened, and the surface is thick and hemp-resistant rough linen, and bundles of hemp rope tighten the explosives bag.

Natasha pondered, this explosive bag was much heavier than the black powder canister, but she had seen the power of the black powder explosion, and it was just a bang, and it would be fine if she was a little farther away.

Allen proposed to use skills to dodge the strongest shock wave generated by the explosion, which shows that the power of explosives is very perverted...... Natasha's cat ears twitched, and the excited expression on her face flashed.
