The allocated Daming warships and supply ships needed to be overhauled, and the craftsmen who were originally unemployed in the dockyard were given jobs again, and their wages were increased by 30%.

They immediately threw themselves into the maintenance of warships for the "Red Banner Army".

At the same time, Huang Han personally commanded the blacksmith master to forge the steel keel.

The city of "Tiger's Den" already had many recruited shipbuilders living there, and Huang Han also asked his master Xu Guangqi to dig up several master craftsmen from the Longjiang Shipyard, which had the most exquisite shipbuilding technology in the Ming Dynasty.

Scientist Xu Guangqi is the master of the Ming Dynasty's technical stream, and he is also a cabinet elder above and below 10,000 people, and he spares no effort to write letters to instruct his protégés to find craftsmen with good craftsmanship and go through transfer procedures to support the great development of the 'Red Flag Army', which is reasonable and legal.

The general officers of the Ming Dynasty, the generals, the commanders of the guards, and other generals made their own weapons, and it was not illegal to produce gunpowder, and the manufacture of artillery was not stopped.

It is also because even the Son of Heaven has high hopes for the "Red Flag Army" and acquiesces to Xu Guangqi to provide Huang Han with materials and manpower, so Huang Han has recruited a lot of talents during this time.

In this era, to build a good ship, a strong ship, the first thing is to obtain high-quality wood to make keel, often such a giant wood is hard to find, and the processing cycle will take several years.

Because the big tree that has just been cut down cannot be processed immediately after it, it must be completely dead and naturally dried before it can be deeply processed, and the processing and molding can not be used, and it must be dried over and over again on the tung oil shade, so the cycle is as long as several years.

The main keel of Huanghan Shipbuilding does not use wood, not only because it is time-consuming and laborious, but also because the quality of naturally produced wood cannot be unified, and it is completely up to luck to get good materials.

How can Huang Han, who is preparing for industrial mass production, grasp the quality of the ship by luck? Therefore, the main keel and ribs are forged steel and tin plated for anti-corrosion.

In order to step by step, Huang Han did not directly open the gold finger to build the terminator "flying scissor sailboat" of sail ships, and put into production the old lock boat with simple technology and high cost performance, that is, the "red single boat" in the Manchu Dynasty.

This type of boat has a large loading capacity, is faster than traditional Chinese sailing boats, and is easier to operate than Western-style sailing boats.

The most competitive is that the cost is cheap, and half of the sailors are used when it is put into operation, which increases the capacity and saves a lot of costs.

However, this type of ship is small and medium-sized ships, generally with a tonnage between 100 and 500 tons, and Huang Han knows that this type of ship is much simpler than the construction of No. 2 and No. 3 Fu ships, and the craftsmen who have built Fu ships under his command are fully competent.

Therefore, he put into production 15 ships at once, of which seven had a displacement of 500 tons and a loading capacity of more than 300 tons, and eight ships with a displacement of 3 or 400 tons.

The existing ships of the water camp were repaired and maintained in the dock, and the sailors did not have a holiday, they were organized to read, read, and learn military discipline, and the military pay was still paid in full during the study period.

The sailors and gunners went ashore to train and study, eat three meals a day, and get full military salaries, and the more than 500 people who had been languishing are now in good spirits. Most of the sailors and gunners were old and weak, and they didn't matter at all.

Huang Han didn't expect them to fight the enemy to the death, what he needed was the seafaring experience of these people.

After constantly communicating with sailors, Huang Han got to know many veteran sailors who had served in the sailors for seven or eight or even ten years, most of whom had been to Japan, and some had even been to Luzon.

This is not surprising, using the imperial court's ship to run private business is the way of civil officials and military generals to make money, and the Ming Dynasty's maritime trade is of course mainly to run the East and South Seas.

The importance of the water division is self-evident, although at this time Huang Han has basically no combat effectiveness of the water battalion, but can not relax the management, Huang Yong, who has the rank of five products and thousands of households, was appointed as the water battalion to confer a thousand general virtual two levels to Funing Weizheng four products to sign the matter to report to the Ministry of War.

Huang Han selected three general flags from the 13-year-old cadets to be issued with bird guns to supplement the water camp, and they were about to be the first batch of sailors to recruit 500 young and middle-aged men from the coastal fishermen to be trained by the veteran sailors one-on-one, so that within six months these fishermen would be able to acquire the skills of independent sailing.

In addition, there are 10 young soldiers of the General Banner who are about to learn to operate the Hongyi cannon, and they are the first batch of young artillerymen with knowledge.

There are 20 veterans who teach the process of fighting artillery, and Huang Han personally selected from more than 100 veterans of the water battalion who can fight artillery.

It is believed that when the artillery produced by the "Red Banner Army" is handed over to them to be fired with live ammunition for a few months, the artillery drill code will come into being, and in the future, it will be enough to continuously accumulate operational experience and continuously optimize and improve it.

With the "Tiger's Den" city as a base, Huang Han once again made a big investment.

Now he not only personally instructed the blacksmiths to use the steel mold hollow casting method to cast steel cannons, and used the hot forging process to forge the fully forged steel keel of thirty or forty meters long, but also instructed the glaze factory to upgrade.

Quartz sand, soda ash, limestone, feldspar, etc., the raw materials for the production of glass, are easy to obtain, and the high temperature of more than 1,500 degrees in the "Red Flag Army" system is no longer a problem due to the air temperature technology.

The high temperature makes the ratio of raw materials form uniform, bubble-free, and meet the molding requirements of liquid glass, and then the liquid glass is processed into products of the required shape, and then heat treated through annealing, quenching and other processes.

After dozens of failures, the master master of the glaze factory successfully mastered the correct method.

All in all, there is nothing that Han people can't learn, even if the cottage starts to accumulate to a certain extent, it will squeeze the original to bankruptcy.

Now the production of glass and glass products in the "Tiger's Den" City Liuli Factory has begun, and dozens of craftsmen specializing in polishing jewelry and processing jewelry are already in the production of polishing lenses and selecting qualified assembled monoculars.

It didn't take long for the eight-fold telescope produced by Huang to come out, which was not a commodity but a standard equipment for officers and scouts above the general flag.

With glass, the technology required to make such a simple monocular is not worth mentioning, Huang Han just gathered the craftsmen who processed jade to explain the principle of the telescope, and they basically understood what was going on.

Among them, there is also a craftsman named Peng Jiawang, who actually saw the Thousand Limiles mirror of the Francois in Jingshi, Peng Jiawang is Chinese New Year's Eve this year, and is one of the hundred and dozens of craftsmen that Huang Han brought from Jingshi.

He has exquisite craftsmanship in processing jade, processing glass is not a problem, and now he knows that the principle of the clairvoyant mirror that was once regarded as a treasure by his colleagues when he was in Beijing is so simple, and the processing technology is not as good as processing jewelry for the royal family.
