"As I walked all the way, I saw some black stones on the streets, and if I looked closely, they were charcoal, although this thing was an ore, but after a long time it could be burned, and it could even burn for days and nights without extinguishing, and its temperature was far better than the fire of grass and trees!" Chen Yuyue spoke.

"Is that true?!" Xu Shu stood up with joy, as far as he knew, there were many such things on the mountains around this new field, and even there were a large number of black stones under this new field, but he never thought that this thing was the charcoal he read in the book!

"Wow?! Really? Everyone was amazed, Zhang Fei took the lead, rushed out of the county office, looked left and right, there were indeed a lot of black stones on the side of the road, grabbed a few pieces, turned back to the county office, and asked Chen Yuyue: "This is it?" ”

"This is it!" After watching it carefully, Chen Yuyue affirmed, and then added: "If you smash it, the burning time will be shortened a lot." ”

"Bang!" With a bang, Zhang Fei crushed the coal stone in his hand, splashed his face even darker, and he didn't know it, and said to Chen Yuyue with a smile: "That's okay, right?" ”

Everyone laughed secretly, Guan Yu frowned and said, "Third brother, wipe your face and make people laugh." ”

With a casual wipe, it became a big face, Zhang Fei didn't care and said, "It's okay, who has flint?" ”

"It doesn't have to be so troublesome, we can just go to the stove and start the fire." Xu Shu didn't laugh, but felt that General Yide was really loyal and worthy of respect regardless of the gains and losses for the great cause of the lord.

Led by Liu Bei, everyone found the stove room of the county government and rushed in. was so shocked that the steward and the cook in the stove room stood solemnly, and they didn't dare to breathe.

Zhang Fei rushed over, stretched out his hand and took out a piece of firewood, put it on the ground, sprinkled it with coal dust, and immediately extinguished the fire, and couldn't help but say depressedly: "Isn't this like soil, how can it be burned?" Some complaining eyes glared at Chen Yuyue.

"It's not like that!" Chen Yuyue explained: "It should be done this way. He took out several sticks of firewood and set them up into a fire, and then sprinkled the pulverized coal evenly on the firewood, and placed the larger pieces of coal on top of the pulverized coal, and then clapped his hands and said, "Wait a while." ”

With the baking of the flame, the soot rose everywhere, choking everyone coughing, but seeing the pulverized coal turn red, and then really burn, it still made Liu Bei's heart happy!

"Sure enough, as the book says, this thing can burn!" Xu Shu smiled, the difficulties had disappeared, and he was in a very comfortable mood: "Lord, Captain Chen has made meritorious contributions and should be rewarded." ”

"Chen Yuyue, you have made a meritorious contribution to the Captain of Fenwei to the Captain of Confucianism!" Liu Bei rewarded without hesitation: "Give three horses of cloth!" ”

Xu Shu said: "The burning power of this thing is not small, as far as you know, in the mountains outside this new field, under the turf of the mountains, forests, and forests, there are all this thing, but some are floating on the surface, and some are buried deep underground. The lord can mobilize the people, mine this thing in large quantities, smash it into powder, and sprinkle it in a valley that the Cao army must pass through, and then two ends and one wall, as long as the fire is together, the Cao army will be defeated! ”

"It takes a long time for this powder to burn." Liu Bei still felt a little unstable, Cao Jun had too many elites.

"Lord, Peng can use the bloodline technique to accelerate the speed of coal and stone burning!" Yan Peng opened his mouth and said: "Peng's Zhu Rong bloodline is the best fire plan, and now Peng has awakened three times, and one time is enough to ignite a range of three hundred steps!" ”

"Good! That's it! When Liu Bei heard this, he didn't hesitate any longer: "Xianhe, Zizhong, Gongmiao, you and the other three mobilize the people, and you must dig out enough coal and stone within three days, hand it over to the second and third brothers, and order the sergeant to smash it." Turning to Xu Shu, revealing a hint of ruthlessness: "Strategist, you take the exploration horse to determine the valley of the ambush, the wound must be narrow, easy to defend and difficult to attack!" ”

"No!" The people took the command. Xu Shu looked at the light rain in the sky and laughed: "With such a light rain, no matter how old Xiahou Yuan is, he will never guard against our army using fire tricks!" Hahaha! God help the lord also! Everyone laughed when they heard this, and felt that what the military advisor said was indeed reasonable.

In Cao Ying, Yan Zhanshu and others were restricted from their freedom of movement, so they could only practice with Cao Jun, and they also saw a little bit of Cao Jun's elite training methods. In addition to the queue that later generations were proud of, there was also a method of formation change, tens of thousands of troops under the command of a few small flags, quickly transformed into a formation with different effects, it is really breathtaking, I don't know how these people trained in the beginning.

Xiahou Yuan saw a few people amazed, so he said proudly: "These elites are trained by the brothers of this general!" If Zixiao leads the army, you can really open your eyes, the Eight Gates Golden Lock Array can be said to be infinitely powerful, and it was this formation that consumed the invincible Lu Bu to death with his blood! I don't know where someone fled in the first place. He glanced at Yan Zhanshu with disdain, causing everyone to snicker.

In the past few days, Yan Zhanshu has probably told everyone about his experience of that copy, so everyone knows why Xiahou Yuan is so targeted at Yan Zhanshu.

"It's so careful, it's still a general." Yu Jiayi said with disdain.

"Ahem!" Xiahou Yuan pretended not to hear it, and didn't care about it like a little woman!

"The art of this formation, the government has never been involved, but I have to consult the general." Yan Zhanshu is studious, and when he heard the words, he asked, it is always good to learn more knowledge.

"The technique of formation is that the general of the unified army uses spiritual power to communicate with the spiritual energy of his sergeants, forming a super spiritual power collection, which has special effects such as attacking, defending, and trapping the enemy according to his personal talent." Xiahou Yuan didn't hide his selfishness, "Generally, generals can learn several formations, the basic ones have attacking phalanxes, defensive circular formations, and the slightly more powerful ones have cavalry blade arrays, crossbow soldiers' crane wing arrays, sword and shield soldiers' fish scale formations, top-level formations, up to now, I have encountered Yuan Shao's halberd, Lu Bu's trap camp, and the heavy party formation that has been practiced, the attack and defense are all at the top, but they are not as good as Zixiao's Eight Golden Lock Array, which has three special effects of attack, defense, and trapping the enemy, which is really powerful!" The first two top-level formations and special troops were all broken one by one by Zixiao's army! "The pride is palpable.

"It is worthy of Cao Zixiao, who has the courage of ghosts and gods, and this day helps Meng Degong!" Ma Yongjun sighed sourly, attracting Xiahou Yuan's admiring gaze and everyone's contempt!

"Tomorrow the third watch cooks, the fifth watch departs, don't miss the hour." Xiahou Yuan reminded everyone before leaving: "Tomorrow we will set off to attack Xinye." And the people took the command and dispersed.
