Time, while Grey Wolf commanded the mining, slipped away completely.

Fifteen days passed in the blink of an eye.

With the Transformers' excavation team, the speed of excavating crystals was nothing short of rapid.

The massive ore vein, from the central position, had several large pits dug down under Grey Wolf's command.

The dark crystals mined were piled up into mountains every day.

Of course, this was mainly due to the radar scanning of the Wolf King.

Once the radar was turned on, even the underground topography was displayed clearly.

Naturally, it was clear which locations had more crystals and which had fewer.

Then the Transformers would directly transform into their excavation forms and target the objectives directly.

Casually reaping on one trip yielded a large heap, and they specifically focused on mining high-energy crystals.

As for the low-energy crystals on the periphery, they couldn't be bothered with them.

It could be said that under high-tech positioning, the primary targets for excavation were Tier Eight to Tier Nine dark crystals.

As for the low-tier crystals casually brought out, they also existed, but they were not used and were instead thrown into the warehouse.

Grey Wolf planned to research a purifier to completely purify the Abyssal Aura pollution from these crystals.

Afterward, these crystals could be sold to Yanhuang Academy, allowing those students studying special power inheritances to exchange them on their own.

Even the mosquito's legs provide some benefits, right?

As for our own people, of course, they'd use the best ones.

And the Female Demon Beast—these days, she truly experienced the joy of level ascension.

In just a few short days, a Transformer directly tunneled to the center of the ore vein.

Then she dove right in, training at the center of the dark crystal ore vein, using the Dark Devouring·Enhanced Version skill.

The amount of energy obtained from absorbing the dark energy within the continent's largest dark crystal ore vein could be imagined.

As a result, just after breaking through the Tier Seven level, she began to ascend rapidly.

In just a few short days, her level soared to Level 79.

Absorbing crystal energy made the dark energy within her extremely abundant, while a portion also converted into experience points.

Once at a high tier, to ascend tiers, one must also accumulate enough internal energy to reach a certain threshold before the tier can be enhanced.

Otherwise, if all absorbed energy were converted into experience points, she could still advance a few more levels, almost breaking through to Tier Eight.

Previously, Mo Qingchen didn't understand why Guardian Beasts with slightly inferior talent got stuck at Tier Six, unable to break through for years.

It's because the energy within the Guardian Beast isn't digitized and doesn't display on the Attribute Panel, equivalent to a hidden attribute.

Each Exotic Beast is an individual, so the energy accumulated within varies.

An Exotic Beast with high talent accumulates energy quickly, whereas low talent accumulates slowly.

In addition, talent also determines the amount of energy an Exotic Beast can accumulate internally.

After Tier Six, each tier breakthrough requires accumulating enough energy to reach a certain threshold before breaking through with enough experience points.

The Female Demon Beast, with Grey Wolf's help, didn't have to worry about directly absorbing dark energy and death energy in the Secret Realm being polluted by the Abyss.

Therefore, she recklessly absorbed everything.

It can be said that Liu Chuanqin's War Elemental Ancient Tree, a year ago, with the help of a tree demon spirit, greatly accumulated internal Five Elements Elemental Energy to breakthrough to Tier Seven.

But balancing the five different elemental energies and absorbing them made his accumulation slower.

This time, coming to the Secret Realm, was also to absorb the Five Elements Energy provided by the tree demon spirits.

It must be known that the energy he absorbed was the tree demon spirits' own accumulation, a painstakingly purified energy.

"There are various energy crystal stones within the Secret Realm, so the Elemental Continent must have them too. We can spend a little money to directly purchase massive amounts of energy crystal stones."

The Secret Realm opens for only fifteen days, giving them very little time to excavate.

Therefore, they only excavated dark crystals this time, prioritizing the Female Demon Beast and Kasi for their use.

As for the accumulation issues of the others, solutions could be found after leaving the Secret Realm.

"Let's go."

Seeing Grey Wolf had left one Tier Five Transformer and a thousand Tier Three Transformers, Mo Qingchen boarded the Wolf King.

These new Transformers were manufactured from the production line in the Wolf King's rear compartment.

The materials used were scavenged from nearby ruined cities.

Life had been extinguished, the world desolate, but remaining relics still held some resources.

They pried open several warehouses, emptied the rusted metal materials inside, remelted them, and fed them into the production line.

Specialized Transformers for mining were crafted by Grey Wolf.

As for the Tier Five Transformer, it was made with materials they brought and some special materials from the Secret Realm.

This Tier Five Transformer had a sub-program of the Wolf King copied into it, issuing excavation orders and inputting their drawn world map.

Before the fifteen-day Secret Realm concluded, they had to leave, but the thousand mining Transformers did not.

They could replenish energy by absorbing dark energy and death energy, though recharging took some time.

Basically, three days of charging allowed for one day of excavation.

"So, after coming back a year from now, we only need to go to the warehouses these Transformers established and directly haul off the various energy crystal stones, and that's it."

Watching Grey Wolf's brilliant move, everyone could only say, well done!

Their next course naturally led back to the edge's ruined temple, where they'd meet with Iron Block and leave the Secret Realm under his leadership.

Wolf King descended on a hill ten kilometers away from the ruined temple, in stealth mode, even the Tier Nine Mechanical Beast Iron Block couldn't detect them.

This time Mo Qingchen, once again in the Combined Gundam, rushed towards the ruined temple.

The various undead encountered along the way had their bad day.

A Gundam over twenty meters tall, running with earth-shaking momentum and bulldozing through, crushed every undead in its path.

Even if they weren't dead, they were missing limbs, becoming crippled.

"Mo, your speed is impressive. Looks like this time's harvest wasn't small."

Seeing the Gundam approaching from afar, Iron Block's mechanical face broke into a slight smile.

This young man was decent; not long after arrival, he sent information about encountering a Tier Nine Abyss monster.

This earned Iron Block a considerable profit, thus he showed an extremely friendly attitude towards Mo Qingchen.

"Thanks for your concern, Teacher Iron Block. This time's harvest was substantial."

Nodding, Mo Qingchen retracted the Combined Gundam and entered the ruined temple.

It was still the same—battered and worn-out, but now bore a few traces of life.
