The rocket used for the test was relatively small and only filled with propellant. Even without actual ignition and launch, Huang Li was able to generate power to determine the flight attitude of the rocket after ignition and launch.

After tinkering for more than two hours, Huang Li and others returned disappointed.

It failed again. The three spiral plates designed by Huang Li had no obvious effect.

But Huang Li was not discouraged, and gave the craftsmen the drawings he designed, asking them to hurry up and continue testing the day after tomorrow.

"Well, this is already a great progress, and we are getting closer and closer to success." Huang Li comforted himself. After dinner, he sat at the desk again and began to design the flamethrower.

There was a fierce fire oil tank in the Song Dynasty. Its structural principle is similar to the piston-type water spray gun of later generations. It uses firepower to push the spray, and the distance should be about five or six meters.

The launching device of the Greek fire includes an oil tank, a manual air pump, a conduit, a nozzle lighter and other parts. The Greek fire must be heated and pressurized before being sprayed, and the valve will be opened to spurt out.

Neither of these two kinds of sprayers was what Huang Li wanted to make and equip. What came to his mind was an ancient firetruck model he saw in a museum and the principle of spraying water to high places.

In the middle and late Qing Dynasty, a hand-held fire-fighting device appeared, similar to later fire engines, and was called a water dragon.

The general shape is a square wooden box with a wooden rod in the middle and a piston device at the lower end of the wooden rod. The wooden rod is pressed from both sides like a "seesaw", and the water in the water tank is forced to spray out through pressure.<

"Then I will report to the court and continue to fight off the bandits." Mulima reached out and clicked on the map and said: "Your army will go south immediately and join forces with the Huguang Green Camp in Dangyang. Then notify Wang Yizheng and march from Fang County to

Xingshan retreats."

"The Wushan Sichuan Army was defeated miserably. Governor Li Guoying, Admiral Zheng Jiaolin and other 80,000 officers and soldiers were all captured. The bandits took advantage of the victory and retreated westward, conquered Chongqing, and then moved north along the Jialing River. Shunqing, Baoning and other cities were occupied..."

Tuhai agreed and said: "It is not necessary to use troops against Shanhui. It is also necessary to retreat and attack Xingshan to completely eliminate its threat to Huguang."

Defeating the Four Banners Soldiers in one battle will be our fig leaf. It will definitely be the worst stimulant to boost the confidence of the Ming army and inspire the resistance of the Han people in the world.

Mulima understood what Tuhai meant, so she smiled and said yes again and again.

Tu Hai was also secretly alarmed by the sudden outbreak of combat power of the Ming army. The defeat of Yiling may not have been accidental, but the tragic defeat of Wushan and the complete annihilation of the Sichuan army made me pay more attention to it.

Could it be that the thieves don’t have any sure-fire way to attack the city? It’s just for defense.

Shan Huishu nodded and said: "Huguang Green Camp can still mobilize about 20,000 troops and is still collecting food and supplies. It will be ready in more than a month. If we give up now, will it be in vain?"

Mulima sat upright from her chair, looked at Tuhai in shock, and said in a voiceless voice: "How is that possible?"

Chuandong looked at the unformed "firetruck" under the paper. Well, it was a flamethrower, and he was very satisfied. Based on what he learned about air pressure, siphon and other aspects of physics, I thought there was no small problem with the principle.

Tu Hai agreed and said: "Half of the bandits have fled to Huangli, so Xingshan's troops must be small. Your combined army is not close to 80,000, which is enough to besiege and destroy them."

Why do I want to break through Maolu Mountain and seize the fake clan? In addition to making great achievements, I also get a small reward. I have come all the way from afar, and I can do anything. I am willing to let anyone go!

Mulima glanced at Tuhai and shook her head, but she was secretly guessing: It should be the rumors and news that there was no fake Ming clan in Maolu Mountain, which stimulated Tuhai.

The fire dragons spurt out one after another, even if they are only less than ten meters away, they are enough to burn the enemy's head. The fire man lets out a shrill scream, stumbles, and crawls, which can definitely scare the enemy out of his wits.

It's not all about making achievements. In Tu Hai's view, the nail in Xingshan is unstoppable, and the containment effect is obvious. It is possible to fully defeat the bandits who have completed the strategic retreat.

"Four Banners Soldiers, hum, come here, let them taste the power of the flame barbecue." Chuandong gritted his teeth, really looking forward to the contest with the Four Banners Soldiers.

Xiangyang.

"If Xingshan is ascending, your army will be able to retreat to the west with all its strength. Although the Sichuan army has not yet collapsed, if you want to retreat from the bandits, you still need to attack from the east and north, or add the Guizhou Green Camp to gradually push back.

, gather together and annihilate them."

………………

The wrought-iron artillery is heavy and suitable for loading under river boats. If fired with shotgun shells, it can wipe out all the soldiers and sailors under enemy boats 70 to 80 meters away.

That is the power of technology. It is also feasible to recreate tank-like protection for land warfare.

Mulima nodded and said: "To the north is the Green Camp of Gansu and Shaanxi, and to the east is your army. Even if it is just a two-way retreat, the bandits can be eliminated, or they can be forced into the desperate situation of southern and western Sichuan."

It can spray kerosene for about seventy meters, which is a standard that Shandong can meet. Even more, I can lower the viscosity of kerosene to make it more suitable for flamethrowers.

Tuhai analyzed it for a long time, not hoping that Shan Huishu would report to the court and continue the retreat with the help of his brother Aobai, the minor minister assisting the government.

According to the commentator, the water jets sprayed by the water dragons can be as high as eight to seven stories high. In ancient times, they were not classified as "low-rise buildings".

For the Navy, Sichuan East devoted all its energy and mobilized all its resources. In addition to trebuchets, rocket launchers, and flamethrowers, it also deployed more wrought iron artillery.

Tu Hai spread out the map, pointed with his hand, and continued: "The bandits attacked Huangliqian and formed a line along the Yangtze River from Chongqing to Xingshan. Xingshan was their eastern backpost."

Tu Hai shook his head and said: "That's true. The imperial court sent the notice. It probably wants to see our opinion. Should we continue to suppress the enemy, or should we change our focus and retreat from Huang Li's enemies?"

After a pause, I added: "If the rumor that the pseudo-Ming clan may be hiding in Xingshan is also reported to the court, it will be even worse."

Tu Hai frowned tightly, put down the notice, and said in a deep voice: "Although it is unbelievable, it should be true. Contact with Wushan has been interrupted for a long time, and I thought it was because of such an incident."

"Bazookas, trebuchets, bows and arrows, artillery, flamethrowers, seven strikes from far to near, we can still dominate the Yangtze River. I really believe it."

Mulima and Tuhai suddenly received a notice from the imperial court. This was a message from Xi'an General Fu Kachan who had been slow to report to the Qing court, and was then sent to Xiangyang in an expedited manner.
