With the hard work of a hundred people, a large area was cleared in half a month, but it was covered with thick soil, and there was nothing of value at all.

The only thing that can be seen in its entirety is the giant dinosaur statue in the middle of the city.

Although Wang Lang had hope for what could be found in the ruins, he also knew that it was extremely slim, and the Lost City did not know how long it had been abandoned, and it was definitely not easy to find information about the dinosaur people here.

After exploring for half a month, the "archaeological team" did not pass on anything valuable, and Wang Lang slowly left this matter behind.

After more than a month of iron-making work, progress has been made, and with the first steel scimitar sent by the Ministry of Industry, it marks that the Xia Kingdom has initially entered the Iron Age.

Compared with bronze weapons, iron weapons are much more complicated to forge, and bronze weapons only need to pour molten copper water into the mold, and polish them after molding, but iron weapons are different, unless there is an advanced process, otherwise you want to be a sophisticated weapon, you must go through a thousand times of forging to be.

The steel made by the blast furnace is not stainless steel, the carbon content is still relatively high, this scimitar has been repeatedly forged, and some patterns can be faintly seen on the knife body, Wang Lang waved the scimitar and slashed hard at the corner of the table.

After the knife passed, the corner of the table broke in response, and when he saw that the blade was intact, he couldn't help but sigh: "It's really a good knife." ”

"Your Majesty, although this knife is extremely sharp, it is very troublesome to forge, and if you want to produce it on a large scale now, you can't do it." The official of the Ministry of Industry said slowly.

Wang Lang looked at the scimitar in his hand and asked in a deep voice, "What's the problem?" ”

"The smelting of this iron ore is not difficult, but using the method of copper to make iron weapons, we found that the effect is not as hard and sharp as copper weapons, and it is very easy to break, but if it is like this scimitar, repeated calcination and hammering, the weapon will be extremely hard, but this process takes a lot of time, just this knife, it will take us nearly ten days."

After listening to the official's narration, Wang Lang knew where the problem was, the improvement of smelting technology could only be explored little by little, and it was already his limit to be able to do this step now, and he still had a way to solve the problem of forging trouble, and he would use animal power or water power if he couldn't do it with manpower.

"I know about this matter, I will find a way to solve it, you have to refine as much wrought iron as possible, even if you can't make weapons now, you can use it to make farm tools." Wang Lang said slowly.

When the official heard this, his eyes lit up, and he said respectfully: "Build farm tools? Your Majesty is really wise, we thought that this iron weapon was useless? ”

Wang Lang said with a smile: "Everything has its use, just find the right way, the mining of iron ore cannot be stopped, if the blast furnace of iron smelting is not enough, build a few more, this thing will be more useful than copper in the future." ”

"Obey orders!"

Wang Lang nodded and said, "You go and get busy first, and I'll inform you after I think of a solution to the forging." ”

"Yes!"

The officer stepped back respectfully.

Wang Lang waved the scimitar a few times, and couldn't help but smile bitterly: "I thought that I could make fine steel with charcoal, it was really a bit whimsical, it seems that the steelmaking process is still immature, and it seems that I can only find a way from the forging method." ”

Putting the scimitar and his own saber together, Wang Lang took out a piece of paper and began to design the forging hammer with a brush.

Although he was not very proficient in chemistry, he was still very familiar with simple machinery.

The river next to Yancheng has a gentle flow, and if you want to use the upper water power to forge, you must build a dam, and with the current ability, it is not difficult to build a dam, but it is definitely not an easy thing.

In order to produce usable steel weapons as soon as possible, Wang Lang had no choice but to settle for the next best thing, using animal power instead of water power.

The power of the ceratosaurus is obvious to all, and if you use four or five ceratosaurs as power, it can definitely increase the forging speed many times.

After more than a week of repeated revisions, the animal power forging hammer was finally designed.

With this drawing, Wang Lang came to the Ministry of Engineering.

The officials of the Ministry of Industry who stayed behind saw Wang Lang coming, and hurriedly went out to greet him.

"I don't know Your Majesty, what's the important thing to do here?" A Ministry of Industry official asked.

"Who's in charge here now." Wang Lang asked.

"Chen, Li Tong, is currently in charge of handling the affairs of the Ministry of Industry." A young official stepped forward and said.

This young man Wang Lang had some impressions, and because of his outstanding performance, he was recommended by Mu Feng as the squire of the Ministry of Industry.

"Li Shilang, see how long it will take to make the things on this drawing." Wang Lang handed the drawings to Li Tong.

After taking the drawing, Li Tong opened it and looked at it, it was a kind of thing that he had never seen before, but Wang Lang explained each part in small characters, even if he had never seen this thing, but it did not hinder his judgment, after thinking carefully for a while, he said respectfully: "Back to Your Majesty, this thing can only be made in more than a month." ”

"The rest of the month is enough, so that you can notify me as soon as the thing is made." Wang Lang said in a deep voice.

"Yes!" Li Tong said respectfully.

After explaining his affairs, in the midst of everyone's congratulations, Wang Lang got up and left.

A few days later, the team carrying the pterodactyl eggs also returned to Yancheng.

When it came to the pterosaur eggs, Wang Lang inquired in detail about the incubation environment of the pterosaurs, and arranged a special person to be responsible for this matter, as long as half of the nearly 100 dragon eggs could be successfully hatched, it would be considered a success.

From the returning officers, Wang Lang learned that before they returned, the harbor had been half built, the wharf had been preliminarily formed, and Mufeng had already begun to build the shipyard, and it was estimated that in another half a year, it should be ready for use.

Although the population of Xia is not large, under the all-round development of sea, land and air, the national strength can be said to be thriving.

Now in the territory of Xia State, counting the prisoners of war who are in service, there is already a population of nearly 30,000 people, and the wild people within a radius of 200 miles have basically been gathered, and the country of 30,000 people maintains an army of 2,500 people, Wang Lang deeply feels that there is not enough manpower.

For this situation, Wang Lang felt that the border should be pushed farther away, and the specific situation in the south was not clear, but in the north, he knew that there were a large number of human tribes, and he temporarily gave up his intention to attack in the jungle.

"It doesn't matter if you are a yellow, a white, or someone, as long as you are alive, you are the labor force of my Xia country." Wang Lang stared at the map, his fist slamming into the northern position.
