With a safe area, the artisans began to cut down the surrounding trees, which were trees with an open canopy, each far from each other, scattered scattered across the grassland.

Although the trees were not suitable for fences, the timber brought by the people was only enough to build houses, and the materials for the subsequent construction would be slowly transported here.

While some people were cutting wood, another part of the artisans began to burn distilled water, and since this time it was all charcoal, even though there were few trees here, with this charcoal, it can be said that the fuel was very sufficient.

Half a month later, a simple semicircular wall was built along the coast, and inside the wall, wooden houses rose from the ground.

The appearance of the building has made people who are far away from civilized society find a sense of familiarity, and they know that they may be here for a long time in the future, and in order to make their lives more comfortable, everyone has put 100% enthusiasm into their work.

With shelter from the wind and rain, Mu Feng began to study how to build this HNA.

In the cabin, Mu Feng spread out a roll of animal skins, which was the harbor design drawing drawn by Wang Lang, Wang Lang was not omniscient after all, there were still some gaps between this design and the actual situation, and it was obviously impossible to completely build the appearance of a picture.

Mu Feng looked at the curvy coastline, compared the blueprint, and drew his own thoughts on a new animal skin.

While Mufeng was busy building the harbor, in Yancheng, the expedition team that went out to look for iron ore brought their discovery, and the expedition team that searched outside for more than half a year walked a long way and found nothing, but on the way they decided to give up and go back, good luck patronized them.

In the distance from Yancheng, that is, near the cliff in front of the fruit forest, the expedition found iron ore, and there was a lot of it.

That cliff Wang Lang knows, the iron mine is located in such a place, which greatly increases the difficulty of mining, not to mention the complex terrain, just the poisonous insects that live there, thinking about it makes people's scalp tingle.

But the iron ore is so close to the location, it is really difficult to get Wang Lang to give up the idea of mining.

The blast furnace had been built, so many preparations had been made, and now that the iron mine had been discovered, if a few disgusting bugs had made it difficult for the plan to give birth, he felt that he had really created this world in this wild world for nothing.

In order to make up for the lack of soldiers, Wang Lang ordered the Ministry of Industry to envy the new soldiers from among the countrymen, these soldiers do not need to go through strict battle training, they only need to know how to obey orders, and they can use weapons to be qualified.

After a month of hurried training, the newly established beast hunting battalion was fully armed and slaughtered towards the cliff.

Weapon attacks are ineffective against these disgusting bugs, so Wang Lang decides to use the extremely skillful methods he has come to this world to deal with these things.

If you want to ask which arson technology is stronger, the barbarian Great Xia looked for Wang Lang, for this arson, as the emperor of the Great Xia Kingdom, he was also ruthless this time, and transferred six hundred catties of high-grade liquor from the household department as fuel for the fire.

After the soldiers followed the forest road to the fruit forest, they rested here for the night, and at dawn the next day, hundreds of jars of liquor were delivered near the cliff.

In order to prevent the fire from spreading into the forest, the soldiers used bronze short swords to cut all the vines on the edge of the cliff before setting the fire.

Whenever a thick vine slides down, there will be a "squeak" sound in the thick vine, causing a riot among the poisonous insects.

After two days of cutting down all the vines on the side of the cliff, the arson operation officially began.

A large amount of liquor fell down the cliff, and a strong smell of wine suddenly appeared in the air, which caused the soldiers to swallow their saliva for a long time.

But at this time, no one dared to take a few sips, this kind of high-grade wine, for those of them who had low alcohol consumption, could put them down in one sip.

After pouring about 300 catties of liquor in a row, the officers of the beast hunting battalion began to order arson.

As the torches were dropped, the alcohol was instantly ignited, and the scorching heat detonated the volatile wine gas, making a rumbling sound.

The bottom of the cliff was like purgatory, and pale blue flames were flying everywhere.

Under the action of alcohol, which is an accelerant, the fire expands rapidly, and the poisonous insects hidden in the vines also feel that their end is coming.

A large number of poisonous insects let out a piercing chirp and quickly crawled away from the flames, but the speed of the fire was extremely fast, and a large number of poisonous insects were burned to death in a very short time.

The poisonous insects crackled under the flames, and the air was mixed with the smell of alcohol, burnt and even a faint smell of roasted meat.

The smell was so disgusting that the soldiers who couldn't stand it quickly retreated until they were back in the orchard.

A day later, when the army reached the cliff again, the scene was already very different from before, the cliff was bare, and the ashes of the burning vines adhered to the cliff face, making the whole cliff look as if it had been dyed with black dye, and there was not a single bug on the cliff wall.

Seeing that the effect of the fire was surprisingly good, the soldiers did the same again, saying that the single-plank bridge transported the remaining liquor to the opposite side, and set another fire on the opposite side according to the method of yesterday.

A day later, after confirming that both sides were burned out, he went back to report to Wang Lang.

After Wang Lang learned about the arson, he couldn't help but admire his genius idea.

After killing a large number of poisonous insects and eliminating the hidden dangers, he immediately ordered the household department to send people to mine iron ore, and ordered the beast hunting camp to clear the wild beasts there, and all wild beasts that exceeded the size of a calf were within the scope of execution.

Wang Lang's practice of species extinction has been regarded as the truth by the Xia people for a long time, until thousands of years later, with the gradual improvement of people's wisdom, later generations of experts began to criticize this person, who was worshiped as a god-like figure in the history of the Xia Kingdom, in their eyes, Wang Lang's practice is inhumane, is the behavior of butchers and tyrants, and greatly affects the diversity of species.

Regardless of the evaluation of later generations, Wang Lang at this time was waiting for the successful mining of the first batch of iron ore with great anticipation.

With iron ore and after refining steel, Xia Guo's weapon level can also be on par with that unknown dinosaur civilization, how to make human civilization continue is what he is most concerned about at this moment.
