As a result, after Dr. Zhang followed Su Li around, he said that there was a river with such a large flow next to this stronghold, and it would be a waste not to use this water power.

All you need to do is build a large waterwheel by the river, which can be used as a power source for the water mill, for the hulling of grain, and even a hydraulic hammer to help make armor.

It just so happened that among the newly relocated villagers, some people said that there was an open-pit iron mine near their village, and the ore could be easily mined and then easily transported to the base for processing.

In addition, Dr. Zhang felt that they should build a few more airships, even if it was just one of the kind of airships with large hot air balloons, after all, the steel-toothed rat king would attack at any time, and it was too inefficient for those pioneer fighters to patrol on the ground, and patrolling in the air with airships was different, even if those steel-toothed rats were hiding in the grass, they could be easily spotted from the air.

In addition, as the scale of the battle expands, it will become more and more difficult to command and dispatch the troops, so if you can take an airship and get a God's perspective, then you can command the troops under your command as easily as in the whole battle game!

Gongsun Lie listened to his friend Kai Kai talking, and said sourly: "You said light, is that big waterwheel so easy to build?" And those iron ores, you have to build a blast furnace or something before you can smelt iron ingots for processing! Will you take this blast furnace? ”

"Aren't these things made with just a hand? You don't study well when you go to school, and you even return these basic knowledge to the teacher! Faced with his friend's doubts, Dr. Zhang replied confidently.

Su Li looked at this kid with a serious face, and felt that the other party might really have some ability, so he quickly reported the matter to Guo Dafu.

Guo Dafu was also very pleasantly surprised when he heard this, and immediately said that he could allocate some manpower to Dr. Zhang, so that the other party could build the big waterwheel, iron-making blast furnace and airship. Anyway, he has enough people on hand now, even if he divides some of them, it will have no effect, and if the other party can really create these things, then the increase in the strength of his territory will be huge.

Speaking of which, now that there are more people, the construction speed of those earthen walls has also accelerated a lot, and Guo Dafu estimates that it will only take a few more days to complete, which makes him deeply understand the truth that there are many people and great power.

Although the area enclosed by this circle of earthen walls is obviously too small and not very suitable for the life of so many people, Guo Dafu is not ready to continue tossing, but is ready to use it as the wall of the inner city, and then slowly expand it later! After the outer city is built, this inner city will become the exclusive residential area of those cronies under Guo Dafu, if they are not cronies, even those players will not be able to live in it, and some of the more important building facilities will also be placed in this inner city, such as the iron-making blast furnace and the like.

After assigning manpower to Dr. Zhang, Guo Dafu saw that the time was not early, so he also went offline to prepare to rest.

As a result, as soon as he went offline, he found that he had received a text message on his mobile phone, and he clicked on it and found that the medicinal materials he had purchased online had arrived.

After giving a five-star review to the store with fast delivery, Guo Dafu opened the door, and sure enough, he found a large box packed tightly at the door.

After struggling to move the big box home, Guo Dafu couldn't wait to open the box and check the medicinal materials in the box.

To tell the truth, most of the various medicinal materials in this modern society have been artificially planted, and the medicinal properties of these artificially planted medicinal materials are definitely not as good as those of wild ones, but they are better than cheap and large, no, Guo Dafu only spent a few thousand to buy such a large box, which is enough for him to refine several furnaces of pills.

What Guo Dafu wants to refine in the real world is a basic pill called Yangyuan Dan, which has relatively mild medicinal properties, and is most suitable for replenishing vitality for people like him.

Recalling the contents of the Danfang in his mind, Guo Dafu began to take out the same medicinal material, and then carefully weighed it, and it took a while to prepare the medicinal materials for refining a furnace of Dan.

Then he put these medicinal materials into a large pressure cooker that had been prepared a long time ago, and began to refine the elixir.

In order to observe the fire at any time, Guo Dafu simply didn't sleep, but stayed by the side to meditate and cultivate. It's a pity that his body is too weak now, and he only vaguely felt a little qi after cultivating for more than an hour, and then it took more than an hour to cultivate the first wisp of internal strength in his body, which is in stark contrast to his brave and refined in the game world.

And not long after Guo Dafu cultivated the first wisp of internal force in the real world, the Yang Yuan Dan was also refined.

Guo Dafu opened the lid of the pot and took a look, and found that he had no experience in refining pills for the first time, and only eight Yangyuan Pills had been refined in such a large pot of medicinal materials, and most of them had been wasted.

And these eight Yangyuan Pills don't look very good, they look like the most rubbish low-grade pills.

The color of this elixir is related to its medicinal power and the amount of erysipelas, the better the color of the elixir, the stronger the medicinal power, the less erysipelas, the worse the color of the elixir, the worse the medicinal power, which contains more erysipelas, so normal people generally like to take those with better color, and those with poor color of the elixir will only be bought and taken by those poorer warriors.

Fortunately, Guo Dafu practiced "Vientiane Decision", and he was not afraid of more erysipelas, so after determining that although the color of the pills was a little worse, there was no problem overall, he directly threw one of them into his mouth.

Different from the Essence Blood Pill, the medicinal power of this Yangyuan Pill is indeed mild, and after the medicinal power is dissolved, a gentle energy is immediately formed in Guo Dafu's body, so that Guo Dafu's body can absorb it relatively easily.

In the face of this energy, Guo Dafu's weak body was like a dry land meeting a clear spring, greedily absorbing and recovering his vitality.

After the medicinal power of a whole pill was digested, Guo Dafu felt that his body had obviously become much stronger, but a layer of black dirt with a peculiar smell also appeared on his body surface, which was some impurities expelled by his body during the strengthening process of the pill and the erysipelas residue of the pill itself.

Guo Dafu, who couldn't stand the smell on his body, hurriedly went to the bathroom to rinse it, then cleaned up the discarded medicinal materials in the pressure cooker, and packed the remaining seven pills in a small glass medicine bottle and stored them.

After doing all this, Guo Dafu saw that it was almost one o'clock in the morning, so he hurriedly went to bed.

Because he was worried about the villagers who had just migrated, Guo Dafu only slept for less than five hours before getting up and going online.

When Guo Dafu went online, the night on this side of the Xuangu Continent had not completely faded, except for those pioneer soldiers who were in charge of sentry, everyone else was still asleep.

The villagers, who had to lay their bunks outside, lit dozens of huge fires to keep warm, and then their bunks were distributed around the fires.

With the help of the flames, these villagers were not frozen by the cold air at night, and they slept soundly one by one.

And Guo Dafu was not the first to go online, and when he came to the R&D department that had just been established, he found that Dr. Zhang, a player, had actually gone online, and was sewing a few pieces of animal skins with a few peasant women.

It seems that the other party is going to use these animal skins to make the airship airbag, and the other party chooses the animal skin of the steel-toothed mouse, although this kind of fierce beast is weak, but the animal skin is very tough, and because the body size relationship is relatively light and thin compared to other animal skins, so it was selected by Dr. Zhang from many animal skins as the raw material for making air bags.

It's just that Guo Dafu is very worried, is it really not leaking from a bunch of animal skins that are sewn like this?

As if seeing the worries in Guo Dafu's heart, Dr. Zhang swore that he had a unique treatment process, which would definitely make these treated hides not leak at all.

Hearing what the other party said, Guo Dafu could only let the other party toss and take a look at it first, maybe the other party really has some ability to make an airship with these simple tools and materials!

As time passed, Su Li, Zhao Jie, Gongsun Lie and others were all launched one after another, among which Zhao Jie seized the time to command his people to make armor after he went online, and Su Li said that he would take his younger brother to tame a mount first.

Guo Dafu is going to go to those villagers today to select some young people to come out, conduct some simple military training, and then, like those pioneers, equip them with winches and heavy crossbows, and turn into crossbowmen.

However, before that, he took out several claws of the black-scaled earth dragon beast and gave them to Zhao Jie, asking the other party to help him create a few new weapons.

As his strength continues to improve, his original weapons are a little inadequate, and the lethality is a little out of reach, such as the spear, the head of the spear is only made of ordinary military steel, and when it comes to a fierce beast with a relatively strong defense like the black-scaled dragon beast, I am afraid that it will not even be able to break the defense.

After talking to Zhao Jie about his requirements for weapons, Guo Dafu found Liu Lin and asked the other party to assist him, select those qualified young men from those villagers, and form a militia force in the territory.

Speaking of which, before these villagers came, in Guo Dafu's territory, in fact, there was no real people at all, although those pioneers and people had a folk character in their names, but in fact, they all belonged to the militia sequence, and in their spare time, they gave the people the construction of strongholds to capture their own strength, participated in all kinds of labor, and in wartime, they all had to take weapons and go into battle with those real pioneer soldiers to kill the enemy.
