The soldiers and civilians of Dongjiang Town who participated in the war still need to recuperate because there are two or three thousand wounded, and now there are nearly 20,000 who need to be strengthened by sea to Phi Dao, Yizhou, Zhenjiang Fort and other places.

Dongjiang Town originally had a battalion, and the battalion of the "Red Banner Army" transferred seven or eight No. 2 ships to participate in the transportation, and the men and horses withdrew quickly.

The "Red Banner Army" not only provides free medical treatment to all the wounded, but also openly promises to accept all people who have been wounded in the service of the country, including those with missing arms and legs.

Huang Long and his generals thought that they were not able to give better care to the wounded, nor did they have the financial resources or ability to accommodate the disabled soldiers and their families.

After all, it is impossible to selectively select wounded soldiers whose bodies can recover and abandon disabled people who have no use value, which is counterproductive and will make most soldiers chill.

Two or three thousand wounded soldiers and civilians were thrown to the "Red Banner Army", and it is possible that half of the wounded soldiers will be able to recover from injuries and return to the team, and Huang Han is not entirely seeking these veterans, he is not short of money, and he is indeed sincerely willing to take care of the soldiers and civilians who are fighting for the country.

Between the capture of a lot of artillery, and a few Hongyi cannons are not very seriously damaged, I don't know if they can be useful, after receiving the news, Shen Cunli took several cannon craftsmen across the sea to Jinzhouwei.

They tried to use the captured artillery to be repaired and maintained to defend the city of Jinzhou, and to transport the Hongyi cannons, which had no way to be repaired on the spot, to the steel foundry for recuperation.

Shen Cunli was overjoyed to see the person who came to pick them up at Jinzhou Wei Port, because the loser was actually his eldest son Shen Ming.

This child has suffered a lot with him as a slave for two years, and he was already precocious, but now he is more stable, and he has grown a lot taller and stronger.

The moment the father and son met, Shen Cunli couldn't help but moisten his eyes, and he happily pinched his son's broad shoulders and said, "Strong, tall, and good-looking." ”

Shen Mingli saluted and said, "Report, Shen Ming, the commander of the cadet army, has received a few officials, please come with me." ”

Seeing Shen Ming so capable, several blacksmith masters were envious, they all had ideas, their sons had to be sent to the "Red Flag Army" as a student soldier when they were old, and they could follow Lord Huang since he was a child, and he had a bright future in the future!

The role played by artillery in siege warfare is obvious to all, and the "Red Banner Army" is keen to use firearms from top to bottom, as can be seen from the fact that even the fierce generals such as Hanzi and Zhang Yang, who are full of force, are obsessed with Minnie guns.

The Furlong cannon was replaced by the Hongyi cannon with a longer range and greater power is the history of the development of artillery in the late Ming Dynasty.

Now he has captured dozens of Franlong cannons of different sizes, and accepted more than 100 traitor gunners led by Cheng Qianyong and Shi Changchun to fight back.

In the past few days, Huang Han has been studying the Furlong cannon that he had neglected before, and found that this cannon is actually closer to the cannon of later generations, at least it is rear-loaded, and it is controlled in the mode of changing the gun, and the gun has the characteristics of the cannonballs of later generations.

In wartime, artillery is not only a waste of time when it is busy reloading, but it is also easy to make mistakes in the busy, and arranging this step of reloading will have the effect of getting twice the result with half the effort when preparing for war.

The Furlong cannon was so advanced but eliminated because the air tightness was too poor, resulting in a short firing range, and the caliber of the gun could not be increased, which could not meet the needs of enhancing lethality.

To completely solve the problem of air tightness, it is not possible to do it in the short term with the current means, and Huang Han, an expert, can solve part of the air tightness problem, although this cannot make the same caliber of the Furlong cannon reach the range of the Hongyi cannon, but at least half of it.

As long as the effective range can exceed 200 paces, it is enough, and it does not matter if the caliber does not go up, it is enough to be able to fire six-pound shells.

Huang Han talked with the master of casting artillery led by Shen Cunli, and found that Shen Cunli and several people had cast Fran cannons without exception.

This is because the Ming army is equipped with too many large and small Furlong cannons, and the output and quality have long exceeded those of the research and development countries.

This is because the mother gun of the Furlong cannon is hollow, just to form a ballistic, do not have to bear the tension of most of the gunpowder explosion, so the process is much simpler, and the sub-gun that bears the explosive force is very short and easy to grasp the casting quality.

Huang Han proposed to use Huang's cannon casting process to cast the steel Furlong cannon, and the cannon casting masters present unanimously recognized that it was a tyrannical thing, because the airtightness of the Furlong cannon was poor, and the mother gun did not need such strength.

Shen Cunli fell into deep thought, he looked at the dozen or so Zi Gong lined up and realized, Huang Han said: "Air tightness determines power and range, why don't you use your brains to increase air tightness?" ”

Shen Cunli picked up a sub-gun and put it into the mother gun, and said with a smile: "Re-process it at the junction of the sub-gun and the mother gun, so that the child gun is stuffed into the mother gun by one inch, so that the air tightness is greatly enhanced." ”

The mother gun and the child gun of the Furlong machine gun are directly docked, and the loose and loose interface affects the air tightness, but if the fit is tight, there will be a cannon fodder after a shot, and the recoil will be slightly deformed, which may lead to the failure of the child gun to be taken out.

Now Shen Cunli's method is to stuff the child gun into the mother gun by one inch to increase the air tightness, which means that there is at least an inch of gap behind the child gun, and the recoil force launched by the child gun acts on this inch distance, which may not break through the tail of the mother gun.

A master named Zhao Shizhong who had cast a Franc cannon was very confident, and he had personally cast no less than thirty Franc cannons in Jizhen before, and he immediately made this problem clear, and Shen Cunli said confidently:

"We have succeeded in producing spring steel, although the production is not high, but it can be used to eliminate recoil on the cannon, and then I will change the design of the Furlong cannon to properly extend the space between the mother guns.

It is estimated that a spring shock absorber can be installed with a foot or so, and at that time, the use of springs and steel plates to resist the child gun makes the mother and child gun basically fit together, increasing the air tightness during launch, and striving for greater range and power.

The advantage of this is that the recoil of the child gun will be cushioned by the spring when it is launched, which not only eliminates the hidden danger of breaking down the tail of the mother gun, but also prevents the child gun from being stuck in the mother gun because it is too disordered. ”

Zhao Shizhong thought for a while and suddenly realized: "Although such a design is not as airtight as the Hongyi cannon, it is not far away, if it is handed over to the villain to cast, there should be no problem with reaching half the range of the Hongyi cannon." ”
