The city is equivalent to putting on a layer of armor for the fragile flesh, which can make the enemy attack!

Jiang Fei's idea was approved by Xiao Ning, and Xiao Ning planned to go back immediately to start preparing.

The matter on the iron mine was temporarily handed over to Jiang Fei, after all, Jiang Fei was already skilled.

It took Xiao Ning six days to rush back to the Yilin clan, and then found the patriarch Yilin Feng and told him his plan.

Of course, Yi Linfeng unconditionally expressed his full support.

So, Xiao Ning gave the drawings and told Yi Lin Feng the concept of the city defense structure.

Then, after countless experiments, Xiao Ning found out how to make the hardest city wall.

Xiao Ning told Yi Lin Feng about the composition ratio of the city wall, and asked Yi Lin Feng to send people to collect a large number of these materials.

Cement, gravel, and so on, these are essential.

When the foundation of the city wall was laid, Xiao Ning left the Yilin clan, and the rest of the things were left to Yilin Feng, and he still went back to the mine over there to stay.

When Xiao Ning returned to the mine, he found that everyone was gathered in one place, as if they were watching something.

"What's wrong?" Xiao Ning stepped forward to ask.

"Elder Xiao Ning, let's dig up something!" the person who was questioned immediately replied when he found out that it was Xiao Ning.

"What is it?" Xiao Ning continued.

"See for yourself. ”

"Come, come, come, Patriarch Xiao Ning is back, everyone let go!" the man immediately shouted.

The crowd suddenly parted ways, and many people called out to Elder Xiao Ning and greeted Xiao Ning.

When Xiao Ning came to the center of the crowd, he saw several dried corpses!

These dried corpses are wrapped around their bodies with something like bandages, a bit like mummies.

Okay, how could you dig up such a thing? It's so unlucky!

"Just dug up?" Xiao Ning looked at Jiang Fei.

"These are just dug up, not long ago, a few more were dug up, but I burned them. Jiang Fei said.

Xiao Ning suddenly thought of something, remembering that when he was cultivating the land of the Yilin tribe, he also dug up a lot of corpses, like a group of tombs.

Now, the mining has also dug up the corpses!

What secrets are buried under this desert island? How can you dig up dried corpses at every turn?

At this time, the patriarch of the Maiss clan, Maisgau, also heard the news, and he was very good at walking.

"Get out of the way, get out of the way. Meisgaard squeezed into the crowd.

"Old Patriarch, do you know what the situation is?" Xiao Ning asked.

It stands to reason that this iron placer mine belongs to the Maiss clan, so Maisgau should know something, right?

"I don't know. Meisgau shook his head.

"How do you deal with that?" Xiao Ning continued.

"Burn it. Maisgau gave him a few deep looks, then turned to leave.

Looking at the departing Maisgau, Xiao Ning was a little speechless, what a strange old man, coming in a hurry and leaving in a hurry.

"Feizi, take someone to burn these dried corpses. Xiao Ning waved his hand.

"Gotcha!" Jiang Fei waved his hand, and several Yilin people stepped forward, took the body away, found an open place, and burned it with firewood.

Mining continued in the mines, and by now, 10,000 iron spears had been made, and forty days had passed.

If this continues, two and a half months will really be able to build all 20,000 iron spears! This is almost the same as Xiao Ning had predicted in advance!

"Hey, Ningzi, what are you doing here?"

On this day, Jiang Fei stared at Xiao Ning's right hand and asked a little strangely.

At this time, Xiao Ning was writing and drawing some lines on a blank piece of paper, looking irregular.

"Maps, I'm mapping a desert island. Xiao Ning said.

"Huh, this thing isn't realistic, is it?" Jiang Fei was a little surprised.

"I don't have to map the whole desert island, but I can record the places we walked. Xiao Ning said.

"In ancient times, marching and fighting wars paid attention to the right time, place and people, and the importance of good location was the experience summed up from one battle after another. ”

"Therefore, in order to deal with the desert island turmoil that may occur at any time in the future, if we can master the map, it is equivalent to grasping the geographical advantage!" Xiao Ning then added.

"It's a lot of ideas, but I think it's too difficult. Jiang Fei said, not believing that Xiao Ning could draw it.

"There are some things that you don't know until you do it. If you give up before you even start doing it, you'll never succeed. ”

"Whatever you do, you can deny the success rate, but you have to try, try to know if it works!" Xiao Ning said.

"This chicken soup, I did it. "Jiang Feiwan.

Another month passed, and 20,000 iron spears were finally made!

Xiao Ning made all the iron spears faint, and put back a thousand people by the way.

So far, there are still 2,000 people of the Ilin tribe who remain here.

These 2,000 people continue to assist the Maiss in mining iron ore.

And during this period of time, the amount of iron ore mined has reached an astonishing hundreds of thousands of tons!

Even if it is smelted into pig iron, it is estimated that there will be 100,000 tons!

With so much iron, even if it is sold as scrap iron, it can be sold for 200 million yuan per ton and 2,000 yuan!

It is no wonder that all those who open mines have money, and this is scientifically justified! As long as you find a rich mineral vein, you will not have to worry about eating and drinking for several lifetimes!

With so much iron, Xiao Ning didn't know what the Maiss clan planned to use it for.

The iron ore around the Maiss clan seemed to be endless, and Xiao Ning and they had mined it for another month, but they hadn't all mined it yet.

Xiao Ning was a little impatient, he still had a lot to do in the Yilin clan, he had to see the state of the city wall, as well as the situation of those animals.

Moreover, now that it is time for spring planting, Xiao Ning has to arrange the spring planting matters.

Therefore, Xiao Ning threw the mess to Jiang Fei again, and he returned to the Yilin clan.

When he returned to the Yilin clan, Xiao Ning instantly felt like he had returned to ancient times.

As far as the eye can see, it is a city wall about three zhang high, that is, about ten meters, and below the city wall, there is a tall city gate.

At this time, the gates of the city were open, and many people came in and out.

On the city wall, there were battlements and towers, and Xiao Ning saw a few sentry men.

Xiao Ning was very satisfied with all this he saw.

Xiao Ning came to the gate of the city, and the people guarding the city saw it and let him go directly.

When Xiao Ning entered the Yilin clan, he found many unfamiliar faces, which made Xiao Ning a little puzzled.

After some inquiry, Xiao Ning learned that these people were all envoys sent by some surrounding tribes.

I heard that the Yilin tribe had built some city walls, so they sent people to check it out, planning to study and study, and go back to make a "turtle shell" for their tribe.

Xiao Ning knew that the construction of the city wall would not be able to hide it sooner or later, because anyone with eyes would be curious to check it.

It's just that I didn't expect it to spread so quickly, and some surrounding tribes have begun to follow suit!
