Luo Heng looked at these black sludge carefully, which was different from the ordinary black sludge, and these black sludge showed a small particle state.

Peat, although this fuel is not comparable to coal, but the combustion power and utilization rate are still much higher than charcoal.

Looking at the huge swamp, Luo Heng wanted to laugh three times, it was impossible to produce peat in the swamp, it could only be at the junction of the swamp and the surrounding area, because all the water generated biogas and other things.

This is wealth, the promotion of the steam engine, and the last obstacle is gone.

The investment in the steam engine is very large, but the efficiency of the machine is not comparable to manpower, take the mine as an example, the use of steam engine air supply, steam engine pumping, steam engine winch transportation of the mine, the output is more than ten times that of useless.

In the past, mining was mostly carried up the mountain, that is, from the bottom to the mountain, so that it was convenient for transportation and then convenient for drainage.

The mine is still mostly filled with other rocks, which also need to be transported out or they cannot be mined.

Manpower drags ore, how much a person can drag in a day, using a steam winch, the amount of one hour is equal to the amount of one person working for several days.

As for pneumatic tools, Luo Heng has no way to promote them, because there is no suitable high-pressure pipe, mainly because there is no suitable material for the hose.

Otherwise, it is more efficient.

"Hurry up and work, it's best to use this black mud. Luo Heng was still worried about how to evacuate, but now he didn't worry, this fortress made of peat was a huge burning fire, and when he left, he would light a fire.

As for whether it will reveal the secret that the soil can be burned, Luo Heng doesn't care.

While Luo Heng was building a lot of construction here, the orc coalition had already sent orcs to summon the message.

"General, there is intelligence. On the opposite hill, a few kilometers away, a tiger man shouted.

"Send it in. "Sitting was a majestic tiger man, a majestic tiger man with a big hairy face with three deep marks on his face, as if it had been scratched by the claws of some wild beast.

"General, the little one is a warrior of the Lynx tribe, and we have found our target, Cheney, the butcher of the dwarven clan. "What came in was the scout of the cat people, the cat people who saw Luo Heng and his party.

"I've seen it, it's really him, what's the situation?" Hearing this, the tiger man general nodded, a distance of several kilometers, condescending, although the tiger man's eyesight could not see who it was, but the size of the head could still be seen clearly.

Now that it was further confirmed, the Lynx captain spoke: "The other party is building a stone wall, which has been built so high, and it is still continuing, and it has also cut down all the trees and weeds on the hillside. ”

"The other side has about 30,000, or even more, mainly wolf cavalry, rhinoceros, bear people, and minotaurs, and we also found that there are also warriors of the flower cat clan, these warriors have fine iron armor, fine iron weapons, and fine iron arrowheads, and the tools for cutting trees and weeds are also fine iron tools, and about half of them have a full set of armor weapons. Captain Bobcat spoke.

"Traitor, traitor!" the Tiger General was furious when he heard this.

The tiger general thought of the other races wearing shiny armor, and wanted to kill each other at that time, and then snatch the weapon armor, only the strongest warrior has the most powerful armor, weapons.

Bunnies, monkeys, mastiffs, these mongrel guys, they actually have armor, what a ridiculous joke.

"Did you find a magician?" asked the Tiger General.

"No, but we found traces of swan people, panda people, hippopotamus people, and mammoths, which seem to be the tribes of the Ural Mountains. The bobcat warrior continued.

The tiger general sneered and said, "Very good, very good, this time I caught the handle and killed those mongrels." ”

The lynx warriors didn't dare to speak, the three royal clans were within the orcs, but they were very arrogant, and beating and scolding were very common things.

"Go down, keep investigating. General Tiger Man waved his hand and said.

The Lynx warrior hurriedly left, and the tiger man general in the tent touched the marks on his face, and then looked at the tiger man standing next to him.

"Bai Huo, you take a thousand people, come with me to have a look. The Tiger General spoke.

"Yes!" Bai Huo immediately went to prepare.

A thousand tiger warriors gathered at the side of the orc coalition camp, and the orc warriors of other races saw this scene and quickly began to gather.

"General Bai, General Bai, are you going to attack the other party?" asked a minotaur wearing black leather armor.

"No, you're all gone, I'll go check it out first. General Bai shook his head and said.

"I'll go too, Guards, assemble!" the minotaur shouted when he heard this.

More than 1,000 minotaurs, more than 1,000 tigers, 500 bears, 300 centaurs, 500 lions, 500 leopards, and General Bai traveled, so many orcs followed.

Toot toot!

When the sentry on Luo Heng's side saw this scene, he immediately blew the horn in a hurry.

"Big brother?" Niu Dali and the others heard the sound of the horn and stood up excitedly.

"Work, if anyone is disobedient, deduct the ale. Luo Heng shouted angrily.

General Bai ran under the sun for ten minutes, and then came here, and saw the stone wall being built on the edge of the mountaintop, and could see some orcs hiding behind the stone wall.

General Bai didn't dare to get too close, at least more than 2,000 meters away.

Bang bang!

With two loud voices, General Bai's face changed.

Two black figures fell from a height of several thousand meters behind them.

General Bai immediately led people to check it out.

Two eagle men with a huge hole in their chests.

Luo Heng stood on the stone wall and shouted, "The people below listen to me, get out of here with your things." ”

"Little white face, it's you, what are you doing here?" Niu Dali asked loudly when he saw the tiger general.

"Haha, Brother Dali, the little white face is going to wash the fart~ shares. Xiong shouted with laughter.

Luo Heng saw several of his subordinates, and shouted angrily: "Don't speak, the lord will speak, and his subordinates can't interject." ”

Speaking of interjection, Luo Heng thought of something out of place in his mind.

"Shorty, if you have the ability, come down and fight with me!" General Bai was so angry that he was short of breath and shouted.

"Little white face, what's the benefit of me winning against you?" Luo Heng asked in a loud voice.

"Bah, you insidious, despicable bastards, have the ability to come down and fight me to the death!" General Bai cursed loudly when he heard this.

Bang!

Luo Heng waved his hand, and the sniper was shot.

Sonor!

General Bai saw the other party's red light flashing, and the bone shield in his hand immediately lifted, and a spark appeared on the shield, and the huge anti-shock force almost hit General Bai directly to the ground.

General Bai was taken aback when he saw a hollow pit that had exploded above the shield.

"Haha, fuck off, you~ Grandpa has spent the winter here. Luo Heng laughed, and was a little surprised in his heart, these orcs have good things in their hands, what kind of good thing is that bone shield, they can actually block their own magic sub~ bullet, and this orc's intuition is very powerful, and they actually blocked the sub~ bullet.

General Bai retreated quickly, and the moment just now really frightened General Bai.

After returning to the camp, General Bai shouted, "Send another message to the Leopard King." ”

"Yes. The orcs below immediately went to prepare, and then three more eaglemen left with the information.

Luo Heng saw the orc retreating, and asked, "Why do you call him Little White Face?"

"He is from the white ~ tiger clan in the tiger clan, and hooked up with a certain war priest in the temple, but he was found by his wife, who is from the black tiger clan, so his wife took five brothers to cut a few big cuts on this guy's face. Niu Dali said.

"That is, no one remembers the original name, and they all call him Little White Face. Xiong opened his mouth and said.

Luo Heng hurriedly asked, "How can a woman beat a man?"

"Why not, in the Tiger Clan, the status of the Black Tiger Clan is much higher than that of the White ~ Tiger Clan, and the women of the Black Tiger Clan marry the men of the White ~ Tiger Clan, and the status of the women is high, and the women of the Black Tiger Clan have five brothers, one is more powerful than the other. Da Mao shook his head and said.

Luo Heng nodded, if Luo Heng hadn't asked just now, these orcs wouldn't have said the reason.

This is also the reason why Luo Heng is reluctant to talk more with orcs in this regard, if he changes humans, he will say that he was beaten without asking, but the orcs will not, and they don't know how to explain more.

"Look, hurry up and get back to work. Luo Heng said angrily.

For the war, Luo Heng was not worried for the time being, after having peat, Luo Heng thought of a building material, green bricks!

Green bricks are better than red bricks, and more importantly, bricks have their own shape, which can be used to build buildings on a large scale, although there are strong people in this world, ignoring mountains and rivers, and any defense, but large-scale wars, still use ordinary soldiers.

The ordinary warriors in the orcs, just like that.

In addition, there is cement, after peat, is cement still far away?

Not far away, with cement, bricks, and steel bars, and a lot of sand and gravel in the valley, then building a new city is not a dream at all.

Luo Heng is doing experiments, peat is made into shapes of different sizes, there are ball stars, there are fragments, there are honeycomb coal shapes, and there are brick shapes, which have holes.

Then the various ratios are done as part of the data collection.

On the third day, the Urals returned, and then another group of old and weak orcs left by boat.

Luo Heng looked at the stone wall that was built, as well as the barren grass in the sun, and then looked at the situation on the other side.

"The orc alliance is not coming back, is there some conspiracy?" Luo Heng muttered in his heart, the army of 100,000 orcs is not an ordinary strength, and it stands to reason that there should be no worries on the fortress side, but the number of orcs here has not increased, which is a bit inappropriate.
