Alex was secretly disposed of, and no one in the entire city knew about it except Jia Zhengjin and Worf. Actually, no one cares!

Jia Zhengjin couldn't do it himself, so the crossbow was also deliberately missed. Just to force Alex in front of that weird man-eating flower.

He can not hesitate when fighting, but in the face of unarmed people, he will still resist in his heart. And give Alex a weapon? That's not going to work, what if one accidentally makes him really run away?

So Jia Zhengjin still chose the safest method. You don't have to do it yourself, and you don't feel uncomfortable.

Wild beasts can occasionally approach near the mines, especially when the imposter dragon flies far away to drink water or return to the city to eat meat. They'll take advantage of it!

The kobold troops stationed in it will fight the beast, and the result will of course be some sacrifices, although in the end they will be able to defeat the beast and leave the miners unaffected.

Such situations occur almost every day, so replenishing the number of kobolds in time is something Jia Zhengjin must do.

Kobold troops patrolling the perimeter are losing more money each day than the mine.

So every day, Jia Zhengjin needs to go to the kobold lair to replenish at least 300 to 500 kobolds. Spending on this alone will result in a loss of at least 10 to 13 gold coins per day. Fortunately, a gold mine was found, so when the gold coins are gone, they can be exchanged for them at the Gold Mine Resource Trading Station. Therefore, such an expenditure is still acceptable!

Then it costs more to recruit soldier bees every day, 1 soldier bee costs 200 raw meat, and 500 is a full 100,000 pieces of raw meat! That is, 100 gold coins are needed every day! This is a bit heart-wrenching, but you have to recruit soldier bees. Because the next time the Bright City or the Majestic Wind Empire comes to attack, they won't be able to resist it if they don't have enough troops.

This is also the reason why Jia Zhengjin wants to domesticate first-order demonic beasts, at least he can minimize the precious soldier bees in battle! If he can, he also wants to capture more powerful second-order and third-order demonic beasts.

About 30 gold ores, 10 silver ores and large quantities of copper ore and iron ore can be excavated every day in the field mining area.

Obviously, the gold and silver ore veins are relatively large, but only a small amount of gold ore and silver ore can be excavated, mainly because the tools are too poor!

If it's a steel pickaxe, or just an ordinary, high-quality iron pickaxe, the amount of gold ore and silver ore that can be mined can be greatly increased.

I knew that there would be a lot of losses, but in order to maintain the supply of soldiers, I had to keep digging.

Therefore, in addition to the main building materials, Jia Zhengjin will try to make tools as much as possible every day to improve the level of tool manufacturing. Now he was only a little bit of experience away from a level 3 crafting skill of normal quality.

Most of the minerals, of course, are the main lifting towers. The current defense of the inner city is already very strong. Even if there is a locust plague like the last one, the arrow tower alone can wipe out nearly half of the locusts. The pressure on the town guards in the city was greatly reduced.

Some of the resources are also used as various building materials for the villagers in the city, such as more public warehouses, garbage collection stations, small shops of villagers, etc.

As for what remains, it will be used as the building of the new city wall outside.

Today's building share is completed, and Jia Zhengjin's manufacturing tool skills have finally successfully brushed to level 3. From now on, all the iron tools he makes are basically of ordinary quality, and the inferior tools of the miners can be replaced.

The materials for the Arrow Tower can be stopped for a day and used for crafting tools, at least by replacing all miners' iron pickaxes with normal quality ones. This way, the mining efficiency will be faster and more materials will come!

Jia Zhengjin led 500 kobold craftsmen, protected by an army of kobolds led by Zhuoma, Buddy, Worf, and Karl, and began to build the outer city wall using hoarded stone bricks within the planned range.

The outer walls have already begun and are now divided into two teams and expanded to the left and right.

The kobold leader, who was leading the patrol on the outskirts of the forest, was in full swing, and he actually tied people up and returned to the city.

On the way, he found Jia Zhengjin and immediately ran over.

"What's the situation?" Jia Zhengjin looked at the dozen or so otherworldly humans who were carried back by the kobold troops and thrown at his feet, and couldn't help but be a little speechless, "It's getting worse or what's wrong?" Are you addicted to being robbers, and giving me people here again and again?"

The kobold leader was stupid, just with his mouth open, sticking out his tongue as if laughing.

Jia Zhengjin came down from the city wall and took a closer look.

There were a total of twelve human beings from the other world who were kidnapped, all of whom were wearing black robes and hoods, and looked mysterious. Among them, two black-robed people can be seen to be women from their body shape, after all, the S-curve is very obvious.

In addition to the twelve black-robed men, the kobold also carried back several large boxes, which looked very heavy.

"Hmm~~" Probably because I finally saw a human being, one of the black-robed people who originally thought that they were going to be reduced to kobolds was writhing desperately.

To say that these kobolds are also immoral, they bind their mouths tightly with ropes, so that they cannot speak. Jia Zhengjin hurried over and helped the black-robed man who reacted the most to untie the rope in his mouth.

"Do you know who we are?!" the black-robed man opened his mouth and immediately shouted loudly.

"Hmm~~" thought his voice was too noisy, and Jia Zhengjin decisively tied him back again. Then he pointed his finger back and forth, and finally pointed to the two female black-robed men.

He walked over and crouched down and said to one of the women, "I'll help you untie the rope from your mouth, you can be quiet and don't scream!

The female black-robed man nodded desperately.

Jia Zhengjin reached out and untied the rope in her mouth, and then asked, "Who are you?"

"We're just passing travelers......" The female black-robed woman had a small black mole on her sexy lips, and her voice was quite nice when she spoke.

However, Jia Zhengjin didn't react, because she was at least forty years old, and she was an old woman twice her size!

Hearing her words, Jia Zhengjin glanced at the box that was carried back by the kobold: "Passing traveler, what is in the box?"

"Nothing!" the black-robed woman looked nervous.

Jia Zhengjin immediately got up and walked over, stretched out his hand to open the lid, and then found that it was locked. He turned around, looked at the black-robed woman and asked, "Whose is the key?"

The black-robed woman hurriedly shook her head, but her eyes looked nervously at the female black-robed person next to her.

Jia Zhengjin captured this moment, so he walked over and bent down to grope gently.

"Bold!!!Do you know who she is?" shouted the black-robed woman whose mouth was loosened, "Don't be rude!"

"Cut!" Jia Zhengjin didn't bother to pay attention to her, found the key on the belt from the other woman, and came directly to open the lock and open one of the large boxes.

The moment he opened the box, the bright light made him a little unable to open his eyes. It was full of gems and gold coins!

"Wow~~" Jia Zhengjin couldn't help but whistle and looked at the kobold leader, "Add meat to you tonight, until you are full!"

"Whew~~!!!" the kobold leader immediately raised his head and let out a cheerful howl.
