Everything that should be ordered has already been ordered, Xiao Han thought about it and walked towards the research institute with his feet raised.

Now this place is already the most important area of Cold Island, whether it is the residents of Cold Island, or Han Yongjian, Xiong Er and others, none of them can enter.

There are also soldiers above the fourth rank of the mortal rank guarding here, except for scientific researchers, only Xiao Han and Ding Yi are qualified to enter here.

Now that this resource area is about to be promoted, and there will be spar mines, the research institute is even more important.

The cultivation of soldiers and the improvement of their strength can only be slowly sharpened with time, but the research institute is different, as long as the policy is adjusted, a lot of practical weapons and equipment can be produced soon.

Walking into the studio where the flame liquid was concocted, Xiao Han saw Chen Xu at a glance, he had now brought more than ten apprentices, two of whom had already left the school.

The number of people who can concoct Flame Liquid has increased, and the speed of concoction has of course increased.

Now, in addition to supplying the smelting of R1 alloy, about six barrels can be stored every day, and this barrel is 100 catties.

For more than a month, almost 300 barrels have been stored, and a warehouse has been specially built for this purpose.

Because I have always had thoughts about the internal combustion engine, the scale of the flame liquid concoction has not only not decreased, but is still slowly increasing, just because this thing is too dangerous, so no one can stuff it into it.

After saying a few words to Chen Xu, Xiao Han continued to walk around the rest of the institute.

Everything here is actually running pretty well.

The smelting of R1 alloy, because of the heat insulation clothing, the scale has not been expanded, and almost 300 catties of R1 alloy can be smelted every day.

These alloys can be used by human soldiers, and they can be used to make about three sets, but if they are tailored for bears and minotaurs, there may be only one set.

But for the sake of the next level 2 resource island, Xiao Han had already instructed Xiao Tie to measure the data of all the bears and minotaurs above the fourth rank of the mortal rank, at least let these stronger ones get better protective equipment.

As for his own soldiers, as long as there is a soldier above the fourth rank of the mortal rank, a set of human-level armor and helmets will immediately be sent.

The number of Terran soldiers currently eligible to wear this equipment has exceeded fifty, and one is added every day or two.

If it weren't for the limitations of the Flame Codex, the increase would have been even faster.

As for the ironsmith shop, in fact, the main job is to create equipment of the fifth rank of the mortal rank, and provide armor and helmets for soldiers below the fourth rank of the mortal rank.

Because of the experience of killing the dwarves twice, there are now three level 6 blacksmiths in the blacksmith shop, namely Rosson, Godot and Baal.

Luo Song was promoted to a level 6 blacksmith because after decomposing Caro's corpse, he obtained a corresponding technology fruit.

Because the human-level axe and armor obtained from Caro were not suitable, Xiao Han had already asked him to transform into three battle knives, one for him, Ding Yi, and Han Yongjian.

It is precisely because of this experience of creating human-level equipment that Godot and Baal, who were supported by the side, also became level 6 blacksmiths.

As for the level 5 blacksmiths, the number of them has exceeded ten, the number of level 4 blacksmiths has exceeded thirty, and the number of low-level blacksmiths is almost two hundred.

This makes it possible for the ironsmith shop to forge thirty or forty sets of equipment in one day if it wants to make every effort to build the equipment of the fifth rank of the mortal rank, which is far more than the needs of the soldiers of the Cold Island.

Because only soldiers above the second rank of the mortal rank are qualified to wear this kind of armor, which can be regarded as an incentive for those soldiers whose strength is not up to standard to work hard to cultivate.

In addition to building mortal-level five-grade equipment, the ironsmith shop also needs to take into account the creation of three-bow repeaters and crossbow arrows.

In the current Cold Island warehouse, the number of crossbow arrows has exceeded 200,000, and even the number of mortal-rank fifth-grade crossbow arrows has exceeded 5,000, and the others are all above the third-rank mortal rank.

These are already finished crossbow arrows, and just the metal used up is already an extremely large number.

When Ding Yi saw it for the first time, he was shocked, all his resources combined, their value was less than half of these crossbow arrows.

In addition to these, because of the construction of crystallized rock buildings, the ironsmith shop is also responsible for the construction of steel bars, but these are the responsibility of blacksmiths below the third rank.

It can be said that after two months of development, coupled with Ding Yi's planning, the work here has actually slowly become regular.

As long as the supply of raw materials is sufficient, it generally does not require much effort to manage.

"My lord, the internal combustion engine you said has been figured out!"

At this moment, an excited voice came from his ears, Xiao Han turned his head to look, and found that it was Ling Yi, and hurriedly confirmed: "Really, did you really get it out?" ”

"I don't know if it's the internal combustion engine you said, but it converts heat energy into kinetic energy."

"Let's go, take me to see it!" After getting such news, Xiao Han couldn't wait.

During this period of time, he has given Ling Yi too many scientific and technological fruits, all of which are related to manufacturing, which has helped him cultivate a lot of talents in this area.

In the research institute, in fact, the scale of the ironware shop is not the largest, but the R&D department controlled by Ling Yi, and its R&D personnel have exceeded 700, more than double the ironware shop.

It is precisely because of the existence of these talents that the production of telescopes now only requires one-third of the labor, and the number of orders for 2,000 Wakaka can be easily completed, and semi-mechanized operation has basically been realized.

There is also the Crystallization Clay Workshop, and because of the existence of this department, the manpower used to crush the black crystal has been greatly reduced.

The emergence of the crusher not only saves a lot of manpower, but also has a better crushing effect, but these machines now have to use manpower to operate.

Xiao Han has always hoped to be able to make an internal combustion engine, and he also has this consideration.

Following Ling Yi, Xiao Han came to the R&D department, and he could hear the "rumbling" noise from a distance, and there were still many people around there, and after seeing the two of them, he immediately made way of a passage.

Along this passage, Xiao Han could already see the iron lump that made a sound, its length was more than one meter, and its height was more than fifty centimeters, and there was a flywheel about twenty centimeters in diameter rotating rapidly.

This is a flywheel that is not driven by human power, and its speed is so fast that even if you are more than ten meters away, you can feel the cool breeze blowing on the flywheel.

"Hey, it worked!" The corners of Xiao Han's mouth curled, a little excited.

With this thing, even ordinary soldiers can be used as mortal-rank third-grade soldiers in the future.

At this moment, a lot of thoughts popped up in his mind......
