Shortly after Simon left, Angela and Maia returned to the city together. There should have been a hearty fight between the two of them, and their faces were much more relaxed.

Jia Zhengjin hurriedly gave each of them a silk bag, which was a gift to build a good relationship.

However, these weirdos didn't get too close to Jia Zhengjin because of the gifts, although the tone sounded very gentle, but in fact there was still a bit of estrangement.

Jia Zhengjin didn't dare to disturb them at will after they returned to the city to act separately. Although Simon is very edible, the most food in Holy Dragon City is now, and the amount produced every day is also quite terrifying, and it is completely deliberately supplied.

Since these seven high-level demonic beasts are unwilling to bother themselves, they can only do this first!

Although Jia Zhengjin was interested in the magic core in Simon's hand, he was a little disappointed when he knew that it was a light demon core and not an electric one. Because if it's a 9th-order electric magic core, how powerful should the stun gun be?

In that case, it is better to concentrate on your own business first. This time, he took more than three million gold coins from selling elves from Sea Dragon City, and got one or two million ransoms from the families of those officials and nobles, adding up to at least more than five million gold coins, this huge amount of money was used to buy resources, enough for him to upgrade several manufacturing skills, and at the same time add fortresses inside and outside the city, all arrow towers were upgraded to the highest level, and the remaining money could also be used to recruit thousands of imperial cavalry and marksmen, and they were fully armed!

As soon as he thought of it, he immediately went to the resource trading station to buy a huge amount of iron ore with gold coins, and when the virtual backpack was completely filled, he rushed to the blacksmith shop and threw all his brains into smelting.

Then he immersed himself in making gun parts, desperately trying to gain manufacturing experience.

For the next week, he spent every day in the blacksmith's shop, so to speak, oblivious to what was going on outside the window. After spending a full million gold coins and more than one hundred and twenty hours, he finally succeeded in upgrading his gunsmithing skill to level 9!

If you want to reach the maximum level, the experience points are really no joke! at least it will cost millions of coins, and it will take more than a week or so!

For Jia Zhengjin, the remaining 4 million gold coins are of other uses, and it is impossible to raise the level of firearm manufacturing in one go, after all, the number of musketeers is not large now. You have to think about the armament of other troops, otherwise how can you fight?

Level 9 gun crafting can already make parts of the legendary quality of the red name and assemble them into a gun of legendary quality! This is enough, and when you earn more gold coins in the future, you will consider rushing to the full level and using the epic firearms.

Upgrading to level 9 is about 1 million gold coins, so the next tool building must be upgraded, weapon building must also be upgraded, and then there is armor building, these three skills are upgraded to level 9, and it will cost another 3 million gold coins! The last remaining 1 million gold coins are the conscription of imperial soldiers and the rationing of equipment.

I didn't expect to spend money like running water, and I finally got so much money, but it was still gone in the blink of an eye!

Coming out of the blacksmith shop, when passing by the beast pen, I unexpectedly found that the fourth-order demonic beast Mitiro and the fourth-order demonic beast Gale Owl inside had been successfully domesticated!

In retrospect, more than 20 days have passed! And it seems like it's the night of a blood moon again!

However, on the night of the blood moon now, there is no initial sense of danger for Jia Zhengjin, even if he does not mobilize any army in the city, he can defend with the arrow tower alone.

After all, since he implemented the policy of cremation of beast corpses on the spot, except for some bones left in unknown corners by predatory beasts, there is no premise that they can be transformed into undead creatures. The few undead creatures scattered around couldn't hold a few hits in front of the arrow tower. Anyway, the residents of the city sleep at home at night, and no one goes out, so they don't have to worry about what happens.

What's more, there are 7 highest-level demonic beasts in the city now, so there is no need to think too much.

Jia Zhengjin took Mitiro and Gale Owl out of the beast pen, and the addition of these two fourth-order demonic beasts would increase his strength a lot.

Gale owls are quite easy to feed just by eating meat. And then the combat power is strong, and the flight speed is also very fast, Mitiro makes Jia Zhengjin a little distressed, this guy needs to eat a lot of gold ore to be able to recover the amethyst energy on his back, and after he is fully recovered, he can turn into a rock giant again and become a powerful combat power! In other words, this is a master of money!

But no matter what, Jia Zhengjin still needs its combat power very much! One point of strength enhancement is one point, only the Holy Dragon City can win this war, so that all the enemies dare not covet it again, and only then can he develop with peace of mind and continue to fight monsters and level up.

Although he felt heartache, he immediately went to the warehouse to take out a large amount of gold ore produced by the mine these days, and piled it all up in front of Mitiro: "Eat! Eat as much as you can, you must quickly recover all your energy, so that your combat effectiveness can reach the peak!"

When Mitiro saw the gold mine, his eyes immediately showed a look of joy, and he couldn't wait to pounce on the small gold mountain in front of him, and directly picked up a piece of gold mine, and chewed it like eating a delicious food.

Looking at the way it ate the gold mine, Jia Zhengjin faintly felt that his teeth hurt. It's metal, not bread! It's so easy to bite through and swallow into its stomach, isn't it?

"Hey~ Can I really afford it?" Watching Mitiro eat nearly half of the gold mine in the blink of an eye, Jia Zhengjin's heart flowed. He could only force himself not to look at this heartbreaking scene, turned around and gently stroked the soft feathers of the Gale Owl, and looked up at this behemoth whose feathers were longer than his height, "It's still hello, you can feed by eating meat!"

"Goo~~" Gale Owl lowered his head and slashed his spiky beak across Jia Zhengjin's body affectionately.

Jia Zhengjin almost fell to the ground, this bird's beak is bigger than his body, if he can swallow himself with one mouth. Fortunately, he knew that Gale Owl was just expressing kindness, so he could only smile helplessly.

Mitiro finally ate only three pieces of a mountain of gold ore that Jia Zhengjin had taken out, and only then did he stop, holding his bulging stomach and looking satisfied.

Seeing that it was finally full, looking at the remaining three pieces of gold ore, Jia Zhengjin didn't know what to say! This amount of food is too terrifying, isn't it? Can this really afford to raise?

The only good news is that the amethyst on Mitiro's back is slowly recovering as she continues to eat, and finally has the color she first saw.

In any case, these two are quite powerful combat power, and they are worth the price if they eat more! It's just that it's a headache to keep a lot of gold ore for Mitiro to keep as food!
