Great Wei Nengchen

"These are treasures. They are hard and fire-resistant, and they don't emit black smoke. Let's dig some more!"

................................................

Just as he was thinking hard, there was a burst of cheers from outside. Xiao Yi quickly sent someone to investigate. It turned out that it was the "digger army" who found a coal mine nearby, which was buried very shallow and had abundant reserves. Cooking is convenient, so you don't have to worry about firewood!

Coal is recorded in the "Shan Hai Jing", and it is called "Shi Nirvana" or "Graphite". Unfortunately, no one knows how to use it. When Xiao Yi was the prefect of Shanyang, he happened to find an open-pit coal mine. Solved the refugee heating problem, and since then, people have started to use coal, love it!

However, in this era, technology is backward, coal is buried deep, and mining is very difficult. Therefore, coal is quite scarce, and it is only used by dignitaries, military officers and soldiers, and ordinary people have to chop firewood for cooking!

After clarifying the situation, Xiao Yi smiled dumbly. Bingzhou is the Shanxi of later generations. It is rich in coal resources and ranks first among all provinces in the world. road!

"Well... coal can burn fire, and flames can destroy the enemy. It's really God's help. Let the squirrel come to see me quickly, and I have important arrangements!"

"promise!"

Chapter 984 Dead Mountain Jedi - Yellowstone Valley!

"Arrogant and high-spirited, the warriors go to the battlefield, drive away the barbarians and kill the barbarians, that is to protect their hometown, the big man is good, hold the sword and gun tightly, fight to the death, and kill the Huns and prairie wolves!"

....................................

After three days of repairing, the army continued to advance, opening roads across mountains and building bridges when encountering waters, defying difficulties and obstacles. In order to boost morale, Xiao Yi made another "Wen Chao Gong" and filled in a poem during the march to make the soldiers shout Singing, for a while, the singing shook the mountains and rivers, and the morale soared to the sky!

Four days later, the men and horses entered Yanmen County, and then camped in Shenchi. There is a natural lake with lush water and grass and fish swimming in groups. It is very suitable for camping. It can be said to kill two birds with one stone!

If you want to defeat the enemy, you must first gain a firm foothold. The [-] troops set up camp and built barriers. In order to prevent the enemy from sneaking in, they dug three trenches, introduced the water from the Shenchi, and surrounded the camp to ensure nothing goes wrong!

After everything was arranged properly, let Ma Liu sit in the camp and handle daily affairs. Xiao Yi led Dian Wei, Cao Xing, ground squirrels and more than a hundred cavalrymen and went straight to Mayi Fortress to investigate the enemy's situation on the spot. Only then can we be invincible in all battles!

"There are high mountains on both sides, and the majestic pass in the middle blocks the way. Even if there are thousands of troops and horses, it is difficult to pass through here. Mayi is known as "one of the three major natural dangers in Bingzhou". Close three points!"

Xiao Yi and the others lurked their whereabouts and came to a high slope. After looking down at the terrain, they couldn't help but gasped. It really was a good battlefield, and it was also a place where heroes were buried!

The geographical situation of Mayi is like a big gourd with thin ends and wide middle, surrounded by high mountains and open terrain inside, which can hold hundreds of thousands of soldiers and horses. As long as the two ends are blocked, it is impossible to escape. No wonder the Han army set up an ambush and chose this place!

Liu Bao is also very good at using troops, with 10 horses distributed on both sides, condescending, and ready to fight. As long as the Han army enters the encirclement, the iron cavalry will charge straight down, unstoppable, and they will all be crushed. There is no way out if you want to escape!

Then again, no one is perfect, no matter how shrewd a commander is, there are also omissions. After careful investigation, Xiao Yi finally found the weakness of the Huns - "Having front punches but no back moves, that is chess Don't care about home! '

Liu Bao's [-] cavalry were all distributed on both sides. The Mayi Fortress in the middle was handed over to the high-ranking remnants to garrison, and only a small number of Huns were watching. This kind of formation has strong attack power but weak defense, and won the battle. It's nothing, once the battle is lost and the Mayi fortress is taken away, the [-] Huns will be the turtles in the urn!

The Han and Hungarians have been at war for hundreds of years, and they have never wiped out 7 enemies. The champion Hou Huo Qubing went to Mobei and charged more than [-] miles all the way. This record is bound to be famous in history and shine forever. Just thinking about it makes people excited!

The problem is that there are heavy troops on both sides, and the city of Mayi is strong. How can the Han army sneak in and take the city in one fell swoop?

"The ground squirrel listened to the order and found me an extinct valley. The terrain must be open and able to accommodate thousands of troops. The grass and trees are sparse and there is no water source. If there is coal in the ground, it would be the best!"

Facing the encirclement of the enemy, only fools go for it. It's best if you fight yours and I fight mine. According to the idea, Xiao Yi started to line up and prepare to compete with Liu Bao to see who is a good hunter , who is the wolf!

"The final general obeys the order, and must do his best to find such a terrain, and live up to Da Sima's great trust!"

More and more ground squirrels came out, with excited expressions on their faces, the opportunity to make contributions by themselves finally came again!

..........................................................................................

"Dragon likes flying phoenix and dancing phoenix, the hole likes to respect the stars, the sand likes to support the army, the water likes to spawn snakes, the dragon likes not to hold the king star, the hole likes the evil star to hide the screen..."

A qualified tomb robber is also a master of Fengshui. It is easy to divide the gold and determine the acupoints, search for dragons and seize treasures. Going out early and returning late every day, going deep into the mountains and exploring the land, is very hard work!

As the saying goes, heaven pays off, after seven or eight days of hard work and climbing countless mountains, ground squirrels finally found a good place, deep mountains and valleys, sparse vegetation, basically in line with Xiao Yi's requirements, here is Huangshi valley!

"That's great!... reward the ground squirrel with a hundred taels of gold and a hundred bolts of silk, and the rest of the soldiers will each have a jar of wine and ten catties of meat. Treat them well!

After hearing the news, Xiao Yi was ecstatic. While making great contributions to the ground squirrel and rewarding the 'Digger Army', he took more than a hundred soldiers to check it out in person. The success or failure of this matter is not sloppy at all!

Yellowstone Valley - located [-] miles southeast of Daying, hidden among the mountains, is a grand canyon with complex terrain, about [-] to [-] miles long, with cliffs on both sides, difficult for apes to climb, and difficult to walk inside, like Coiled snakes can accommodate thousands of troops in the wide area, and only one rider in the narrow area. The uncanny workmanship of nature is amazing!

In addition, there is no water source in the valley, the vegetation is sparse, and there is not a single small tree. Occasionally, we encounter a few clumps of weeds, which are also scorched, dry, and half dead. As for birds and animals, there is no shadow at all!

Fire overcomes gold, metal overcomes wood, wood overcomes soil... According to the theory of the five elements intergrowth and mutual restraint, where the vegetation is sparse, the ground must be short of water and rich in gold. That is to say, there are a lot of minerals in the Yellowstone Valley!

The ground squirrel and others also dug a few holes to see if there was gold, silver, etc., but they found nothing, but a kind of yellow-brown stone, which can be seen everywhere in the valley, which is also the origin of the valley's name!

"Precipitous cliffs, strange rocks like forests, it really is a dead mountain, the terrain is wide enough to accommodate thousands of horses, and the Huns will surely die if they enter this place!"

Xiao Yi is quite satisfied with the terrain of Yellowstone Valley, it is very suitable to set up an ambush to lure the enemy, the fly in the ointment is that there are some things missing in the valley, if the plan is deployed, the lethality may drop sharply?

Besides, the yellowish-brown stones in the valley attracted Xiao Yi's attention, and he picked up a few pieces and studied them carefully. This thing is very strange. It's not rocks, pebbles, or gravel, and it looks familiar. Could it be yes……

"Heaven help me, great things can come true. With these treasures, the Huns will die without a place to die...Thank you physics teacher, thank you geography teacher...haha!"

After researching for half a day, Xiao Yi recalled his school memories, and suddenly laughed out loud, these yellow-brown stones were exactly what he dreamed of!

Coal is black, snow is white, gold is yellow, blood is red... these simple truths are known to three-year-old children, but what most people don't know is that coal also has other colors. The yellow-brown stone is a kind of coal, which later generations call it: lignite!

Thousands of years ago, the branches, leaves and roots of plants accumulated into humus, which was buried underground due to changes in the earth’s crust, isolated from the air for a long time, and underwent a series of complex changes under high temperature and pressure to form a combustible fossil. This is Coal is gone - mostly pure black!

However, there is a kind of coal that is unlucky, buried in the ground for not enough time, and because of the movement of the earth's crust, it returns to the ground again, forming a kind of 'half coal', which is grayish brown in color!

This kind of brown coal has many impurities, low ignition, insufficient combustion, and releases toxic gases. Therefore, people in later generations don’t like it. Even if they find lignite mines, they don’t bother to mine them. To kill people, but it couldn't be easier to use, poisonous gas, colorless and odorless, it can kill people invisible!

The plan in his mind was made, Xiao Yi ordered the 'Digging Army' to station in the Yellowstone Valley and build some large warehouses to store grain and fodder for the army to use. In addition, he specially dispatched manpower to dig the yellow-brown stones, The more the better!

There is nothing wrong with choosing a safe place and hoarding the army's food and grass before the army moves, but what everyone is puzzled about is that Da Sima is so happy, is it really just for hoarding food? Could there be another reason?

Facing everyone's doubts, Xiao Yi smiled and did not answer, but seriously told the chinchillas that after the 'digger army' settled in, one must be careful about fire prevention. The food and drinking water for the soldiers were all cooked outside the valley, and those who dared to start a fire inside the valley --Kill without pardon!

Running around all day, sweating profusely, the valley was full of dust, and it was uncomfortable to stick to his body, forming a layer of hard scabs. After leaving Huangshi Valley, Xiao Yi decided to take a bath to relax his body and mind. The water quality of Shenchi is very famous. The world!

There are many streams and luxuriant vegetation near Shenchi. Everyone chose a stream with beautiful scenery and clear water, and prepared to wash it well. But when the team came to the front, they encountered another team, drinking and resting by the stream!

"Password?—Where are you soldiers?"

"It's not good...they are the Huns, everyone is ready to fight!"

………………

At the beginning, I thought I had encountered my own rangers, but upon closer inspection, these people had flat faces, slender eyes, and disheveled hair. They turned out to be a group of Huns. School King - Uwe!

At the same time, Uwe also recognized Xiao Yi. Back then in Xuchang City - the Imperial Palace, the two faced each other tit for tat, and they had compared their strength. The first warrior in the grassland faced the first warrior in the big man. The process was quite exciting. In the end, Xiao Yi With superior skills, he won face for the Han Dynasty!

When the enemies met, they were extremely jealous. Both sides drew their weapons at the same time, and a fierce fight began...

"Kill it! --Slaughter all the beards, the big man wins!"

"Come on! --Kill all the Han people, the Xiongnu will live forever!"
