After the test flight of the Divine Fire Crow, Qin Xiaobai was greatly satisfied with its performance, and estimated that the frontal battlefield on the side of the world would probably not be able to support it for long. So he made all-round preparations for the battle, and asked the carpenter shop to rush to work immediately, and within three days, he could make as many Divine Fire Crows as he could. At the same time, he ordered someone to pass on 300 million gold, and asked Jin Fat Man to help him collect the basic materials for making gunpowder. Then there is the upgrade of the barracks, Qin Xiaobai has long wanted to upgrade the king-level barracks to the highest emperor level, so that Mulan can give full play to the strength of her historical famous generals after being transferred. It's just that he has been short of money before, even if he fought guerrilla warfare a lot later, it was still not enough, but fortunately, this redemption copy made Qin Xiaobai earn a lot of money, so Qin Xiaobai, who was wealthy, immediately ordered to upgrade the barracks. There are also buildings that need to be promoted to the top, as well as administrative halls. Qin Xiaobai had already given an order to transfer Wu Meng to Heifeng Village as the deputy head of the village to assist Zhang Muzhi in mining, and the position of deputy village head of Yandang Village was handed over to Li Lingyue. Wu Meng did not resist Qin Xiaobai's order in the slightest, because he knew most deeply that Li Lingyue, who was a historical-level figure, was far above him in strength, so he was deeply pleased that the lord could have such a great talent to assist. Therefore, at this time, Yandang Village was already in charge of Li Lingyue. And Li Lingyue is worthy of being Wu Zetian's daughter, known as the strongest princess in history, even if the current Li Lingyue is still a little Lori, but her political ability is still extremely strong. When the village first came to her hands, because the level was too low and the attributes were not high enough, the operation was sluggish for a short time, but as Li Lingyue's experience was rapidly upgraded, the operation of the village also continued to increase rapidly, Qin Xiaobai saw this, in order to let Li Lingyue better exert his strength, so Qin Xiaobai spent a lot of money, and decided to upgrade the administrative hall to the highest emperor level. Now that these three days have passed, the administrative hall has been upgraded to the prince-level, and Li Lingyue has also become a prince-level lord. Now, under Li Lingyue's governance, the village's production capacity is several times faster than before, when it was in Wu Meng's hands. This made Qin Xiaobai overjoyed, the production capacity of a territory was the most important factor in the strength of that territory. And because of Li Lingyue, it only took three days for the carpenter shop to produce thirty Divine Fire Crows. Thirty Divine Fire Crows can transport 60 troops, don't underestimate these 60 people, if you can use them well, you can instantly join the battlefield in a surprise attack from the sky, then sometimes it can play a key role in the battle situation. However, Qin Xiaobai was still not satisfied, and the Shenhuo Flying Crow flew into the bandit's cottage, and it took a period of gliding to stop, but not every cottage has such a large space, so Qin Xiaobai made improvements to the tactics of the airborne troops, that is, to turn the airborne troops into real airborne troops, a Shenhuo Crow can take three people, one can be a pilot, and the other two will jump off the Shenhuo Crow to join the battlefield in a surprise attack when they fly to the low altitude of the enemy's territory. The pilot, on the other hand, can control the Divine Fire Raven to fly back and refill the gunpowder, and then carry two soldiers to continue the process just now, so that the airdrop can be used repeatedly. The only concern was whether the soldiers who fell from the sky would not be harmed, making them unable to fight for a short time. Qin Xiaobai's 500 soldiers are all heavy cavalry, and when they dismount, they are heavy infantry, and they are covered in iron armor and swords, but they are difficult to protect from shocks. So Qin Xiaobai ordered someone to fill the armor of the soldier with cotton wool as a shock absorption. But he didn't know if this could be recognized by the system, and he also let people experiment again, and it was found that it could really achieve shock absorption, and the soldiers wearing thick armor could also form a certain impact force when they fell from a low altitude, causing range damage to the enemy like a human flesh stone, which made Qin Xiaobai happy. At the same time, it also allowed Qin Xiaobai to discover a new tactic, airdropping troops. When all 500 soldiers are finished, they can decorate the stones, rolling wood, tung oil or something, and throw them into the dense places of bandits in the cottage from the air to suppress the bandits. Or in the future, when you encounter something difficult to attack, when you need to fight a protracted battle, you can pull the Divine Fire Crow out from time to time to sneak around, throw some gold juice or something, and disgust them to hit the enemy's morale...... Shenhuo Flying Crow, a multi-purpose machine, home travel, killing people and goods, essential items. As for the commander of this air force, it is naturally handed over to Mulan. In the past three days, the barracks of Yandang Village have also been upgraded from the king-level barracks to the emperor-level barracks. At this stage, even the generals under the top ten guilds in the Huaxia District have no opponent for Mulan. Hua Mulan was not familiar with the new type of airborne troops, but she was very interested, and under Qin Xiaobai's teaching, she quickly mastered this branch. Relying on its powerful command ability, the airborne troops cooperated very well with each other, whether it was loading gunpowder, boarding, falling to the ground, and quickly arranging after parachuting. Now 30 Divine Fire Crows, 500 heavy airborne troops are ready, plus Zhang Muzhi, who can fight back at any time, and there are nearly 3,000 Level 5 soldiers available in Heifeng Village. At this point, Qin Xiaobai now really has the strength to storm the city and sweep Yandang Mountain. But of course, it is impossible for Qin Xiaobai to rush out in a daze, if the army of bandits desperately returns to Yandang Mountain, then he will be given dumplings and swallowed in one bite. It is necessary to contain the army of bandits, and how to contain it, of course, it depends on the fierce battle of Lei Feng in the frontal battlefield. At this time, in order to make the 'world' more authentic, the system has further weakened the player's various benefits, such as the friend communication function has been turned off. Fortunately, Qin Xiaobai had the foresight to buy some carrier pigeons in advance, so that he could keep in touch with all parties at all times. After everything was ready, Qin Xiaobai wrote a letter and sent it to the world. Qin Xiaobai is still confident in his ability to fool, and at this time of the frenzied battle in the world, he has almost been forced into a corner, and if he doesn't strike again, he can only be consumed by the army of bandits.

Therefore, after Qin Xiaobai sent the message to the flying pigeon, he could take Hua Mulan to command 500 soldiers out of the wild goose swing and sweep the lair behind the bandits.
