As the hot air is poured in, the hot air balloon slowly bulges and gradually turns into a ball. At this time, the hot air balloon has actually been filled, but the buoyancy is not enough and it does not stand off the ground.

Song Yingxing did not order anyone to stop venting air at this time. He just ordered a few Jinyiwei to carry the hanging basket and kerosene lamp holder next to the hot air balloon and prepare at all times.

It lasted for about a cup of tea, and the bottom of the hot air balloon finally slowly broke off the ground, and it was about to rise!

Song Yingxing quickly pulled out the black wire behind the fan, and then directed the Jinyiwei to remove the horn from the hot air balloon and hang the rope of the hanging basket on it.

Then he ordered people to fix the kerosene lamp bracket to the iron hoop at the bottom of the hot air balloon, and to minimize the kerosene lamp, and then fix it on the bracket.

At this time, the hot air balloon was completely erected. If it weren't for the fact that there were a few Jinyiwei standing in the hanging basket, it would have been taken off the air. Song Yingxing immediately said excitedly: "Master Lu, General Qin, call the flag bearer over and stand up. Remember to let him bring a telescope."

When Qin Gongming heard this, he immediately looked at Lu Xiangsheng to see what he had.

Lu Xiangsheng thought for a while and said decisively: "Call the artillery commander over."

Qin Gongming nodded, then said loudly: "Go and ask Chen Han, the commander of the artillery division, to come."

After hearing this, a personal soldier immediately rushed to the artillery position. Soon, a young general in the uniform of a major general followed behind the guard and came to the horse.

Although this general is young, he is very heroic. He has a handsome face and a gentle and resolute attitude, and his tiger eyes are tough and murderous. He is obviously a rare general.

He came to Lu Xiangsheng and Qin Gongming, and turned over and jumped off the war horse, put his legs together, raised his head and chest out, and gave a standard military salute, then said loudly: "The last general Chen Han met Marshal Lu and General Qin."

Lu Xiangsheng looked at the telescope hanging on his chest, nodded, and then ordered: "You go and stand in that hanging basket, wait until you rise into the air with the large Kongming lantern, observe the situation in the basin, and see if there are any blind spots."

Upon hearing this, Chen Han gave another standard military salute and said loudly: "The last one will obey the order."

Then, he threw the reins to the guard beside him and ran towards the hot air balloon without hesitation.

When Song Yingxing saw Chen Han running over, he immediately asked all the Jinyiwei in the hanging basket to climb out, and held around the hanging basket, and let Chen Han crawl in. Then he went forward and carefully explained the adjustment method of the kerosene lamp and the precautions for the hot air balloon.

After hearing this, Chen Han nodded to show his understanding. Song Yingxing carefully checked it again, and then shouted excitedly: "Everyone should pay attention, one, two, three, let go."

With his order, the Jinyiwei, who was holding the hanging railings around him, released his hands at the same time, and the hot air balloon slowly floated into the air.

Chen Han slowly turned the kerosene lamp according to the method taught by Song Yingxing, and the flame gradually approached the bottom of the hot air balloon, and the hot air balloon rose faster and faster.

Amid everyone's amazement, the hot air balloon finally rose to a height of fifty feet, and the thick hemp rope at the bottom of the hanging basket was pulled straight.

Chen Han on the hot air balloon stabilized his figure, then picked up the telescope and looked at the bastion in front. After scanning it carefully several times, he put down the telescope, turned the kerosene lamp down, and then made a gesture to complete the task below.

Seeing this, Song Yingxing below immediately asked several Jinyiwei to pull the hemp rope down. Soon, the hot air balloon was pulled back to the ground. Chen Han described the situation above to Song Yingxing, and then climbed out of the hanging basket and ran towards Lu Xiangsheng.

When Lu Xiangsheng saw Chen Han running over, he immediately asked, "How about you, can you see the situation in the castle?"

Chen Han bowed and said, "I could see the situation inside the ridge, and there was no blind spot."

When Lu Xiangsheng heard this, he couldn't help but praise: "Okay."

It's so great. With such a magical artifact, it's easy to suppress the firepower in the brink. With just a few rounds of flowering and bullets, the artillery in the brink will basically be silenced. With the armored chariots, the attack on the brink is like walking on flat ground!

He thought about it and immediately ordered Qin Gongming: "General Qin, you send someone to set up a camp five miles behind, and then set up a legion as the size of a legion. Let's live here and practice it well."

Lu Xiangsheng was really excited at this moment. With the two magical artifacts of hot air balloons and armored combat vehicles, the Tsarist Russian bastion has become vulnerable in front of the Ming army. There is absolutely no problem in taking over the Siberian Plain next year!

After he told Qin Gongming that he ran to Song Yingxing, and thanked him solemnly. Song Yingxing gave this gift so good. This hot air balloon is not only useful in the bastion offensive and defensive battles, but also in other places.

For example, after setting up the camp, hang a hot air balloon over the camp and send a sentry to watch it. Who else can sneak attack the camp?

For example, when the two armies are facing each other, if such a hot air balloon is hung in the formation, you can see the enemy's formation. Then make targeted arrangements. Wouldn't you take the initiative every step!

Of course, these all require drilling, time to explore and summarize.

From then on, Lu Xiangsheng also became an experimental madman. He directly led all his generals and most of the Dingliao Army to live outside the bastion. He practiced, practiced, and practiced every day. All kinds of tactics had to be practiced repeatedly, and all kinds of data had to be measured repeatedly, and all kinds of firearms were used.

For example, the attack distance of the bastion artillery, how far is the live ammunition, how far is the flowering ammunition, and how far is the shotgun. He had to let the cannons in the bastion fire and measure them repeatedly.

For example, if the armored combat vehicle is damaged after being attacked by live ammunition, he directly parked an armored combat vehicle within the range of the bastion artillery, and then directly bombarded repeatedly with solid bounces.

For example, how fast the small armored combat vehicles were digging the city wall, he directly ordered people to drive the armored combat vehicles under the city wall and dig them out, dig out the city wall, and dig one after another!

When he was excited to the point of drilling, he even climbed into the hot air balloon basket, rose to a high altitude, and directed directly with flags. The madness seemed to be back when he personally led his army to rush up the city wall and killed everyone.

After repeated drills, he finally came up with the best solution to conquer the bastion, that is:

First, use one hundred Shenwei cannons to calibrate through hot air balloons, and fire several rounds of flowering bullets to destroy the turrets in the turrets as much as possible, and then use a shotgun to suppress them, which directly silences the cannons in the turrets;

Then, ten large armored combat vehicles and ten small armored combat vehicles were on board at the same time. Each chariot followed by a hundred infantry and pushed them directly under the city wall. The large armored combat vehicles and half of the infantry were covered, and the other half of the infantry cooperated with the small armored combat vehicles to dig the city wall together.

Finally, use infantry to cooperate with a simple small armored combat vehicle to rush up from the gap, occupy one layer of bastion, and then continue to the next level. This small combat vehicle does not require artillery or a large hoe, but is just an iron shell. Just open a few rows of shooting ports!

After testing, it will be enough to conquer a bastion in this way!
