The junction of the human realm and the giant territory, the former dining highlands, now the falling snow city.

Thick columns of black smoke rose from the snowfall city, mixed with firelight, a loud roar of metal clashing, and the shouts of soldiers training.

The entire Falling Snow City is in full swing, and it has been completely transformed into a huge barracks and arsenal.

Escorted by the Demon Gold Warriors and the Demon Gold Chariot, vehicles continued to come from the White Bone King City to Falling Snow City. These vehicles were extremely heavy, and they contained the treasury of various countries that Li Yunfei had looted during this period of time, as well as the "tuition fees" of those aristocratic students, all of which were some rare alchemy materials.

Among them, the two basic materials of Mithril and Magic Crystal have the largest quantity.

After entering Falling Snow City, these materials were immediately transported to the factory, and then under the supervision of Duke Kao, they were refined into parts of those powerful magic gold equipment.

His Majesty the Bone King then personally carved the final circuits on these pieces, giving them life and becoming powerful magical gold equipment.

Although many alchemists have been trained in the Alchemy Research Institute, none of these alchemists can engrave the final circuit of the magic gold equipment. Even if they could see the circuits, they wouldn't be able to replicate them. The main reason is that these circuits are so complex that each line is thinner than spider silk, and it also involves the balance between various energy circuits, so that there can be no mutual interference of energy pulses.

Only His Majesty the Bone King can engrave this last alchemy circuit.

"Boom...... Rumble...... Boom ......" a heavy footstep sounded, and a swarthy war colossus walked out of the factory, the chest of this war colossus was also engraved with the symbol of the hammer head of the six-pointed star Ouroboros, and the number engraved on the back was "500"!

This is already the 500th Colossus of War!

At this time, in the Falling Snow City, the city walls were almost everywhere with towering war colossicons, silently looking at the wilderness in the distance, ready to enter the battle at any time.

A cluster of war colossias of this scale can be said to be invincible.

In the period of time after Li Yunfei was crowned as the White Bone King, small-scale giant sieges also happened a few times, but after those giant groups of people came to Falling Snow City, they were like some fragile glass, easily smashed on the walls of Falling Snow City.

Hundreds of war colossias were dispatched at the same time, and those low-level giants were literally reduced to papier-mâché.

The 500th Colossus of War took two steps, leaped onto the side of the wall, and then jumped down again, into the wilderness in front of Falling Snow City.

At this time, in the wilderness, there were about a hundred war colossias walking around, either practicing defense or fighting.

These Colossias of War are the most recent additions to the list, and their operators are training hard to be able to annihilate more enemies in future battles.

This batch of War Colosses, numbered from 401 to 500, is the latest batch of War Colossius.

Compared to the first 100 Colossies, the latest batch of Colossias of War appear to be more fluid in appearance, completely adopting a streamlined design, and the joints are slightly slender and more flexible. At the same time, their power transmission systems are more efficient.

These changes are some of the new improvements that Li Yunfei has made after making hundreds of war colossus.

Some of the existing problems have been corrected, and some new optimized designs have been added. It can be said that the new batch of war colossias has increased by about half a percent compared with the first batch of war colossias in terms of agility and other combat effectiveness.

Don't underestimate this half-percent increase in combat effectiveness, for a black iron-level powerhouse, it is a small level difference, and it is even more obvious in large-scale battles.

At the door of the factory where the 500 War Colossus walked out just now, a figure slowly walked out.

The moment this person appeared, the six Demon Gold Warrior guards guarding the door immediately knelt on one knee at the same time and saluted, "Your Majesty!"

Li Yunfei bowed his head slightly and said, "Get up." ”

"Your Majesty!" several guards stood up at the same time, their eyes flashing with excitement. They had only received the task of guarding this factory before, but they didn't expect that the person working inside would be His Majesty the White Bone King! How could they not be excited!

Li Yunfei didn't have time to take into account the thoughts of these warriors, but jumped and came directly to the city wall, looking out at the wilderness.

At this time in the wilderness, the training of the 100 war colossias was in full swing, and these latest war colossias were more flexible and looked more beautiful, almost like a huge black iron bodybuilder.

It's just that Li Yunfei didn't feel too happy, but frowned slightly, not knowing what he was thinking.

"Your Majesty, I wonder what Your Majesty is worried about?" a voice sounded behind him, looking very worried.

Li Yunfei didn't reply, and said, "Kao, you're here, you've worked hard these days." In the past few days, he and Kao have been assembling the War Colossus in the factory, working for more than ten days in a row, assembling more than 20 War Colossius, which is extremely hard.

Kao bowed, then raised his head and said, "Your Majesty Xie cares, but alchemy is my life's pursuit, and I never feel hard. What Your Majesty is worried about now should be the shortage of alchemists, as well as the improvement of the combat power of the War Colossus, right?"

Li Yunfei nodded and said, "In the past few days, you should have also seen that the combat effectiveness of the War Colossus has almost reached its peak...... You don't have to call me Your Majesty, but call me Dean, which I prefer in comparison. ”

The new batch of war colossias has been improved by half in terms of combat effectiveness, and there are some other improvements, but this is the end of it. After all, these war colossias are still just some war equipment, not real black iron giants. They need people to operate.

No matter how much they improve, these war colossias can't reach the silver level of combat power.

And although the combat power of the black iron level is enough to apply now, it is not enough in front of the silver giant. In future wars, no one can guarantee how many silver giants, or even golden giants, will appear, so this black iron-level war colossus is still not enough.

"Lord Dean, you should also understand that the reason why the combat power of the Colossus of War has reached the peak of what it can achieve is mainly due to one reason, and that is limited by the materials it uses...... After all, the Iron Spirit, though hard enough, is just as bulky and not tough enough......," Kao said, frowning.

"Moreover, it's not just a matter of materials, although our Alchemy Research Institute has cultivated a lot of alchemists, there are almost no real grandmasters, and if you want to cultivate this kind of talent, you still need the alchemy grandmaster to teach it. Kao continued.

It's just that he also knows that the real alchemy grandmasters, the great masters, are generally talents only found in the Golden Emperor City, and they are all treated as treasures by various countries, how can they run to the forefront of the war between humans and giants and come to Falling Snow City.

The silver-level war colossus, and the alchemy grandmaster and the grand master...... Li Yunfei's eyes narrowed and he muttered to himself.

At this moment, an attendant hurriedly ran over, knelt down on one knee in front of him, and said, "Your Majesty, several guests from the Lionheart Imperial City have asked to see you, and one of them claims to be the alchemy master Xue Li, saying that he is familiar with His Majesty. ”
