The latest weapons startled Captain Powey and them.

Zhang sent a hot air balloon that can carry two people into the air!

The appearance of this hot air balloon is associated with cassava silkworms.

In terms of silk, Zhang Daozhu was unwilling to rely on the Great Song Dynasty completely, and he was also unwilling to have the technology of pot packer silk reeling and printing and dyeing in the silk industry!

The price of raw silk in the Great Song Dynasty is rising every year, and there is not only seasonality, but also production uncertainty!

The owner of Zhang Island had to compete with the merchants of the Great Song Dynasty for raw silk at a high price------ which made people feel aggrieved.

A few years ago, he first built a celluloid greenhouse, domesticated different varieties of silkworms to eat the tender cassava leaves drenched in wood vinegar, and after repeated cultivation, he finally found two varieties that can eat cassava leaves!

The wood vinegar can not only have the effect of disinfection and insect repellent, but also promote the formation of amino acids in the silkworm body.

This kind of liquid formed by the natural condensation of the flue gas produced by simmering in the charcoal kiln only needs to be allowed to stand, which is one of the magic weapons that Zhang Island Master refuses to tell others easily.

Finally, after several generations of cultivation, his cassava silkworm baby finally formed a scale and successfully produced raw silk!

It's a pity that the cassava raw silk is thicker than the silkworm silk, the color is yellowish, and the fabric feels rougher, even the white merchants of this era can see that it is not as good as the silkworm, and refuses to give the same price as the silkworm------ but it is cheap, strong, and can be raised in the greenhouse in all seasons, we just want the silk of the poor, why not?!

The first batch of fabrics produced by Zhang Island is not for sale, he keeps it for hot air balloons.

He designed a two-layer fabric with tung oil on the outside to make it more airtight and water-resistant.

The joints are repeatedly glued with heat-resistant gums-------

Wang Defa's family made large gasoline blowtorches and hot air balloon inlet equipment, so that with the help of large hand-cranked bellows, the heat of the gasoline blowtorch can be successfully lifted into the air.

Zhang Daozhu found Captain Mu Mu and asked him to find someone to test fly------ due to the simple technology, they quickly trained the first batch of air forces in this time and space.

This type of hot air balloon can be tethered or untethered, and the temperature is raised and lowered to complete the take-off and landing.

Experiments have proven that it is the best way to observe on the battlefield------ and it can be used to communicate with the people below by dropping small boxes, or by using signal flags.

Captain Bao Wei was so happy after getting the hot air balloon that he himself went up to test the flight, and he didn't need to fly too high to observe fifteen kilometers away, two hundred meters was enough!

He also hired a painter and asked them to draw a flying eagle on a hot air balloon, because it was too big, and the painter was not very high, and from a distance, it looked more like a crow.

As early as when the Tatar bandits set up camp, everyone discussed that there was no need to use new rockets in advance, it would be possible to make them gather more, their new rockets were not as many as the old ones, and when they were all gathered------- new rockets could play the greatest role!

The entire defensive position was well arranged, but what Captain Bowe never expected was that when he went all out to observe the Tatar cavalry approaching in the distance, the battle would be launched from his rear first!

Zhang Hongfan personally drove a four-wheeled/large carriage and took the remaining six carriages to the back door of the defensive position.

Along the way, he passed by several teams of carriages from time to time, and in order not to attract the attention of others, he did not arrange for anyone to grab the carriages.

The seven of them were loaded with a large number of dead soldiers and explosives/powder packs, in fact, before they set off, the commander Boyan had already promised that as long as they could succeed, they would be knighted, and even if they died, their families could still get such a reward!

Zhang Hongfan saw two large cross-shaped pointed wooden horses placed vertically at the gate, and it was obvious that the sentries there were not worried about anyone sneaking up on them during the day!

There were four sentries at the gate, two on the ground and two on the watchtower------ all of whom looked relaxed.

He sneered in his heart.

When he reached the door, two sentries with spears on their backs stopped him.

One of the sentries looked behind them and said, "Hey, why aren't there any logisticians?" ”

Zhang Hongfan said respectfully: "The little one doesn't know ------."

"Why are you followed by so many people??"

"I don't know if it's small------- I really don't know!"

"Show me your citizenship card!"

Zhang Hongfan took one out of his arms and handed it to him.

The sentry then said to the other sentry, "Shiro, you go and let those people leave------ they will be of no use at all, they will only add to the chaos!" ”

The sentry went to ------- sentry looked at Zhang Hongfan's citizenship card and said, "You are Wang Dalang from Tianjia Town?" ”

"The little one is exactly!"

"Okay, you go down and open the door, I'll see what's in there------"

Zhang Hongfan didn't move, and said, "------- the car door is locked!" ”

"It's strange, it's all sausages and canned food, why do you lock it?"

As he spoke, he tried to open it himself, and it was easy to open------ but a short spear pierced his throat like a viper!

Zhang Hongfan heard a strange sound in the seat of the carriage, and knew that it was to solve the sentry, so he immediately drove the carriage and began to rush towards the barracks at a rapid speed!

He didn't do anything but break through or disrupt the pirates' defenses!

The six wagons behind him also sped off as fast as they could, and another sentry could be seen lying there in the dust!

The crowd at the back of the convoy also started running!

Rush, rush!

The two sentries on the watchtower were actually alert when Zhang Hongfan started driving, because they didn't see the sentry downstairs giving a gesture to allow them to enter!

Moreover, looking in this direction, the carriage just blocked their view!

But as soon as the first car drove by, they saw the sentry lying in a pool of blood!

They quickly picked up their spears and fired at the driver of the first car------ but both shots did not hit the driver, but they made two holes in the car, and there was a scream!!

The two of them didn't have time to load, so they immediately took out a copper whistle and blew it suddenly!!

In fact, the sound of gunfire was already an alarm------ the logistics area of the entire defense area was suddenly chaotic!

Zhang Hongfan knew the general layout of this defense area in advance, and he believed that as long as he passed through here, the next place would definitely be a military point, so he did not let the people in the car get down in advance, let alone let them drop valuable grenades/bombs and explosives/medicine packs!!

He ran desperately in the carriage, but, it was so hateful, how could there be so many wooden houses in this logistics area, not like their barracks with supplies in the open air------ he noticed that from time to time pirates running out of the wooden houses shot at him, but he ignored them, did not fight them, just drove and took the lead in rushing forward!
