In addition to the improvement of the bird gun bullet, Sun Yi also made a slight modification to the firing of the Tiger Squat Cannon. Pen % fun % Pavilion www.biquge.info

When the Ming army first used the tiger squat cannon to fire shotguns, it was first loaded with gunpowder, compacted, and then loaded into small projectiles, and finally pressed on a large projectile, using the weight of the large projectile to achieve the effect of "holding breath".

Later, the Ming army developed to the point that there was no need for large projectiles, and the small projectile layer on top of the gunpowder was mixed with yellow mud, and after the yellow mud solidified, it played a breath-holding role similar to that of a Trojan horse, but the strength was much worse than that of a Trojan horse, and the solidification time was too long.

Sun Yi's method has actually been popularized in the electric three-eyed gun: using gypsum gauze as a closed air. After the small projectile was loaded, the gypsum gauze was dipped in water and pushed into the barrel and pressed, and it initially condensed after dozens of millimeters. The strength is greater than that of yellow mud, and the gypsum absorbs water during the solidification process and does not wet the gunpowder. In the absence of gauze, the effect is the same as that of mixing weeds with plaster.

After the experiment, this method not only greatly shortened the battlefield time for the Tiger Squat Cannon to reload, but also increased the firing range by 20 feet.

One more foot farther is one point stronger.

Sun Yizheng instructed the gunners to practice, and the staff came to report that a fleet of ships had come down from the upper reaches of the Yellow River, playing the five-pointed star flag.

A dragon is coming.

The mighty fleet is so magnificent.

The armored raft led by Bu 19 was larger than the three rafts of Bu 19, and when he landed, he deliberately made a turn on the spot.

Deputy Commander Bu 19 hurriedly stepped forward to greet him, and as soon as a dragon appeared, Bu 19 made a complicated and strange fist clench.

Before the dragon had finished its equally strange return salute, Bu Jiu jumped on the raft.

Bu Jiu stomped his feet vigorously, hehehe, "Big brother, this bilge is wooden, right?" ”

A dragon said a little ostentatiously: "Three whole poplars are made of vertical keels, and horizontal logs are made of rafters, all of which are nailed into wooden frames with iron nails from our wolf mountain, and then covered with reeds." ”

Bu Jiu excitedly pinched the boat gang and found that the boat gang was still made of reeds.

"Second brother", Yilong couldn't hold it back, and directly introduced the key points, "Come on, show you something good." ”

A dragon pulled Bu Nineteen to the center of the cabin near the stern, where several stout sticks protruded from the bottom of the raft, along with two wooden wheels.

A one-stop introduction: "I asked the brothers to snatch the craftsmen's two log bellows, forcibly dismantle the overturned carts of the two Wang Erniu, and replace them with two water tanks that can spray water, which are installed at the bottom. ”

A dragon stood on a wooden wheel, stepped on the wooden wheel like a walker in the future, and a stream of water bubbled out of the tail of the raft with flowers tumbling over flowers.

"You can still reverse!" The dragon laboriously pulled a wooden pole, still stepping on the wooden wheel, but the splash at the end of the raft was gone.

"One tank reverses, one tank forwards, and you can spin in place!"

Bu Jiu smiled and climbed onto another wooden wheel.

The eldest brother and the second brother of the Wolf Mountain Hall took off their shoes and stepped on the wooden wheel vigorously, and the large armored raft that had just landed on the shore drew an arc and hung its head in place at one hundred and eighty degrees.

The raft turned into a face of the Yellow River, and a dragon pulled the wooden pole again and shouted: "Oh oh oh oh"

The two of them bowed their heads and shouted in unison:

"Ho Xi Zuo, Ho Xi Zuo Ho Xi Zuo,

Hi ~~~~~~~~ Hi!

Whoa, ahem! Cough! Cough!

Yo ho ho!

Ho ho

Oooooo

Ho Ho West Left, Ho Xi Left Ho West Left Ho West Left ......"

The wooden wheel under his feet flew over, the water at the tail of the raft rolled, and slowly, the raft went upstream!

A line of rafts of various sizes passed by the large raft, loaded with various supplies, and behind each raft was a piece of racked field.

As soon as Sun arrived, the two were already sweating profusely and re-docked.

It turned out that Yilong and Wang Erniu rushed to Changsheng Township on the day when Mo Rigen led the horse team to set off. Because Bu 19 took the walkie-talkie, the two did not understand the development of the situation on the front line, and just kept their heads in preparation for supplies and ordnance.

Yilong stayed up for a few nights to supervise the construction of this water jet raft, and immediately led the team down to support the front line, but Sun Yi did not receive the order to let him stay in Changsheng Township.

It was estimated that there were no vegetables on the front line, so the dragon ordered each small raft to not only transport supplies, but also drag a field covered with artemisia.

Taking advantage of his prestige among the poor rafters and the Yellow River slender man, Yilong organized a team of more than a dozen "water monkeys" with Brother Pao as the backbone to bring them down.

"Since you're here, let's stay." Sun Yiyi.

The whole of Temu was accustomed to quick radio commands, and this was the first time that there had been such inconsistencies.

But thinking about the other side, it would take a day and a night for the forward battalion to return to the camp to ask for instructions once, and Sun Yi was relieved.

"Master, since the eldest brother is here, the commander of the naval division will let the eldest brother do it, right?" , Bu 19 asked Sun Yi.

"Huh! This big raft is for you, and my raft is there. A dragon hand and a finger.

A slender spinnaker with a one-person spinnaker and banana reed raft for a dragon is tied to a racked field.

"Second brother", Sun Yile asked Bu Nineteen hehehehe, "Do you say that the deputy chief soldier is the commander of the navy?" ”

Bu Jiu suddenly realized, "Hey, I almost demoted my eldest brother!" ”

Although the dragon came uninvited, the raft guests he brought solved a big problem.

Bu 19's sailors immediately underwent a major personnel adjustment. Bu 19 personally led the water-jet armored raft and appointed three senior rafters as captains of the armored raft. Each armoured raft was equipped with sailors, gunners, archers, and the simple three-eyed guns, which everyone asked to use. Each armored raft is also paired with three or four small rafts to form a small fleet.

A dragon came uninvited, and also evacuated the raft passengers of Changsheng Township, and the waterway transportation from Changsheng to Qingshanzui was temporarily paralyzed.

In other words, the "superfluous" rafters stranded in Qingshanzui should abandon their boats as soon as possible and return to Changsheng Township by land.

When Huatou Cabinet heard the news, he ran to ask Sun Yi in a hurry.

"Master, I don't plan to ask for these rotten grass rafts, how about giving Russia a big trip? There's still a lot of goods that haven't been brought back. ”

Sun Yi immediately understood.

It's no problem to drive a raft down the Yellow River to Dabanshengcheng, but it's impossible to come back and let a raft full of goods go upstream.

Not only did the slippery ghost take a fancy to these rafts, but he also had the idea of a wealthy labor force in the Mozhigen Horse Team.
