There are 1,000 high-level Warcraft crystal nuclei (95 of which have reached the standard of the best power source), 5,000 medium-level Warcraft crystal nuclei, and 10,000 low-level Warcraft crystal nuclei.

Under the work of the swift robotic bugs, a large number of diamond-like crystal nuclei were quickly sorted out.

"The Warcraft Crystal Nucleus itself is a material for making various magic weapons, like the core part of the Magic Crystal Cannon, which is the crystal nucleus used. The Raynal Empire has a huge land area and many cities, and the number of Warcraft crystal nuclei needed is also huge. Therefore, it is ideal to have so many surplus crystal nuclei in the treasure vault. However, the royal treasure vault of the Raynald Empire doesn't even have a power source?"

Zhang Feng felt a little unacceptable. After all, even the Trazes family can get two life sources, how can the royal family of the Raynal Empire not have one?

The mechanical prospector ants continued to search, but found no other treasure space.

"Well, I have killed and captured many noble people in the past, such as Miguel, the sister-in-law of the Trazes family, who put all his treasures in the space ring and carried them with him. I believe that Emperor Hildrit also has this habit!"

Zhang Feng could only pin his hopes on Emperor Hildrite. Capture this boss, everything is understood. To say that the royal family of the Raynal Empire didn't even have a source of life, Zhang Feng would not believe it no matter what.

This is the most lacking thing in the Machine Empire.

"The power source of the middle and high ranks is handed over to the mechanical warriors, and it immediately devours evolution. The best power source is sent back to the base and production starts immediately. ”

With Zhang Feng's order, the surrounding mechanical warriors rushed up, each devouring a power source, and began to evolve.

In addition, there are 95 swift mechanical insects each holding a top-notch power source and running towards the nearest sub-base 64.

Evolution is going on at the fastest pace.

The existence of mechanical prospecting ants makes all crystal nuclei and other precious resources become the fire of the night, which is clear at a glance. In the palace, in the mansions of the nobles, the homes of the great merchants...... All places where crystal nuclei could exist were swept away by the mechanical army.

Every minute, an unknown number of high-level mechanical warriors are born, and then they rush towards the battlefield outside the city non-stop.

Drops -

"Report to the owner, find Zijin. ”

The mechanical sound of the main base made Zhang Feng immediately ecstatic.

"How much purple gold is there?"

The scene cuts to a group of mechanical warriors attacking a low building.

The soldiers guarding the building were quickly slaughtered, leaving only corpses strewn across the floor. On the low building hangs a sign with several large tadpole-like characters written in the local script. Zhang Feng immediately learned the meaning of these words from the main base - "Imperial Honor Exhibition Hall".

The Imperial Honor Exhibition Hall is actually similar to the existence of military museums on Earth.

Zhang Feng quickly thought of a possibility. Just waiting for verification.

The mechanical prospector ant gave a guiding signal, and the swift mechanical bug stepped forward, waving its claws, and quickly destroyed the building, cutting a large hole in the hard wall.

The mechanical warriors rushed in.

I saw that in the huge exhibition hall, the most conspicuous position was a huge dark purple inscription.

Zijin!

Zhang Feng's conjecture was verified. According to the text next to it, this is a battle hundreds of years ago, the Royal Heavy Armored Knights of the Raynal Empire and the Hebrew Family's Flame Dragon Heavy Armored Knights jointly took the initiative to defeat the Orc Bone Witch Tribe, pursued all the way to the core of the Bone Witch Tribe, and snatched back the symbol of their tribe - the obsidian ancient monument.

The obsidian ancient monument is an extremely important symbol of the orc tribe. The Orc Tribe is a 36 powerful tribe with 36 obsidian ancient tablets. It is said that the great wizard of the orc tribe was able to exert great combat power with the help of the obsidian ancient stele.

Of course, no way to use obsidian has been discovered, and the ancient obsidian monument has become a symbol of pure honor, displayed in the Empire's Hall of Honor, flaunting the honor of the Raynald Empire, especially the Raynals and the Hebrews.

Now, this obsidian ancient monument is naturally cheaper than Zhang Feng.

"Zijin, weighs 1562 kilograms. The mechanical voice of the main base prompted.

"1562 kg. The evolution of the second-level main base to the third-level requires the consumption of 1,000,000 units of energy, 100,000 tons of common metal, 50,000 tons of synthetic metal, one ton of Mithril, and one ton of purple gold. Energy, common metals, synthetic metals, and mythril have always been a problem, and now even purple gold is available. That is, the main base can be upgraded. Hahaha......"

"It's a pity! It's only one and a half tons, and after the upgrade is completed, there will be half a ton left, and I'm afraid I can't even upgrade a sub-base. If only one main base is level three, even if there is a level three troops, it will not be able to scale up and will not play a decisive role. ”

"It seems that we still have to hurry up and conquer the northern orc grassland! Fortunately, the appearance of this obsidian ancient monument proves that the little fat man Adamson is not lying, and there is indeed a purple gold existence in the northern orc grassland; just by conquering 36 orc tribes and getting 36 obsidian ancient tablets, I can evolve 50 third-level sub-bases. Hahaha...... It seems that the day is not far off when the mechanical army will be collectively upgraded to the third level. ”

"Arnold personally took action and sent Zijin back, and the main base immediately began to evolve!"

The important surname of the obsidian ancient monument made Zhang Feng dare not be careless at all.

Immediately afterwards, the mechanical prospecting ants found a small amount of purple gold in this imperial honor exhibition hall, totaling more than a hundred kilograms.

These purple gold are all from all kinds of witchcraft seized from the orc wizards by some emperor [***] team, strange shapes, everything. Naturally, it was all shipped back.

"Upgrading the second-level main base to the third-level requires the consumption of 1,000,000 units of energy, 100,000 tons of ordinary metal, 50,000 tons of synthetic metal, one ton of Mithril, and one ton of purple gold. It takes 24 hours to level up, during which time no mechanical classes can be produced. All the materials are ready, are you upgrading now?" asked the main base mechanical voice.

"Upgrade now!"

"Yes, upgrade immediately! Please leave the main base for a while!"

Zhang Feng strode into the base wormhole, and the next moment, he had already appeared in the No. 1 sub-base.

The No. 1 sub-base is hidden in the belly of the mountain, which is the most difficult to be discovered, and the density of the surrounding sub-bases is the largest, and when it comes to safety, it is definitely the first of all sub-bases, and even above the main base.

Drops -

The main base made a soft sound, and in the flickering red light, it turned into a huge meteorite and entered the state of evolution.

"Hmm? There didn't seem to be such a big movement when I was upgraded from level 1 to level 2 last time! This time, the entire main base has returned to its most primitive meteorite state, and it seems that there will be a qualitative improvement. I don't know much about it, but it looks awesome......!

The main base was about to advance to the third-level state, and Zhang Feng had a faint expectation in his heart.
