I am the Arcane Archer, and all my skills are self-created.

Li Wu had not studied engineering, but he was not completely ignorant of these mechanical structures.

After all, we've all repaired things to some extent in real life, and they all contain various mechanical structures.

He carefully studied the blueprints, including the structure of the parts and the routing of the circuits.

"So that's how it is..."

Li Wu quickly understood the principles behind the modification.

The so-called modification actually involves changing the arrangement of several key components inside the energy core and resetting the puppet's command system.

The original command was to attack any unit that was not of the same type.

The modified commands are to obey the orders of the person who holds the modified core.

Once you understand the principle, the rest becomes much simpler.

Li Wu stretched out his finger and carefully probed into the energy core, beginning to manipulate those tiny, crucial components.

This process requires a great deal of endurance and control.

If not handled carefully, the entire energy core could be rendered unusable due to incorrect connection of components, leading to energy imbalance.

Li Wu held her breath and focused all her attention on her fingertips.

Time passed second by second.

Five minutes later, the last component was put back in place, the energy core trembled violently, and the red light turned into a soft blue.

[System notification: You have successfully modified the puppet's energy core and have mastered the basic life skill, Engineering.]

"It's a success!"

Li Wu looked at the blue-glowing core in his hand and breathed a sigh of relief.

Unexpectedly, by sheer chance, I've unlocked some life skills.

Without stopping, he immediately picked up the second energy core and began to modify it.

With the experience from the first time, the speed was significantly faster the second time.

The second core was also completed in just three minutes.

Half an hour later, all eight energy cores were transformed into blue.

Li Wu installed a modified core into the chest of a relatively intact mining golem wreckage.

A soft click.

The energy core is perfectly embedded in the groove.

Immediately afterwards, the circuits on the puppet began to light up one by one.

Click click click.

The puppet, which had been falling apart, began to automatically absorb the parts on the ground and reassemble itself.

In less than a minute, the intact mining golem stood up again.

Its crystal eyes also emit a soft blue light.

It walked up to Li Wu, lowered its steel head, and made a mechanical sound.

"Command received, in standby mode, please issue command."

Looking at the obedient giant in front of him, Li Wu felt a great sense of accomplishment.

He pointed to the Star Iron Ore Vein and gave his first instruction.

"Go, dig all those ores down for me."

"Command confirmed, begin execution."

The mining golem turned around, picked up a pickaxe, and walked heavily to the ore vein.

Then it raised its pickaxe and began to strike tirelessly, one strike at a time.

clang!

clang!

clang!

With each strike, a fist-sized piece of star iron would break off from the rock wall.

The efficiency was many times higher than when Li Wu dug by hand.

Li Wu didn't sit idle; he installed the remaining seven cores onto the other puppet remains.

Soon, eight mining golems lined up in a row, forming an assembly line in front of the ore vein.

Li Wu only needed to follow behind them, bending down to pick up the pieces of Star Iron he had dug up and put them into his backpack.

The system notifies you that you have obtained Star Iron x1.

The system notifies you that you have obtained Star Iron x1.

……

The progress towards the target is increasing rapidly.

(30/600)

(50/600)

(80/600)

……

(600/600)

In just three hours, they had already collected six hundred pieces of Star Iron.

And less than a third of that rich ore vein has been mined.

"That's all money."

Li Wu's eyes lit up as he looked at the remaining ore veins.

Star Iron is a rare forging material, and its price has always been very high in auction houses.

If this entire mineral vein were mined, it could fetch at least several dozen gold coins.

"Keep digging!"

Li Wu issued the order without hesitation.

The eight puppet miners swung their pickaxes once more.

Li Wu sat to the side, picking up ores while opening the auction house to check how the equipment he had previously listed was selling.

To his delight, he discovered that all the high-quality equipment had been sold, bringing him nearly two gold coins in income.

Those rare pieces of equipment with decent stats also attracted a lot of bids.

Especially the Blade of Fury that was revealed, the bidding has already reached 6 gold coins and is still rising.

"It seems there are quite a few people who know their stuff."

Li Wu closed the auction house interface with satisfaction.

With this money, plus the income from mining, they'll have enough start-up capital to establish a guild when Hua Zitong returns.

Just as Li Wu was envisioning the future, a tremor suddenly came from deep within the mine.

Rumble.

The entire mine was shaking, and loose rocks were falling from above.

The eight puppets that were mining also stopped what they were doing and turned their heads in unison to look at the source of the vibration.

In their electronic eyes, a wary red light began to flash.

"Something big is coming."

Li Wu immediately stood up and gripped the bow tightly in his hand.

He could sense a powerful aura rapidly approaching from the depths of the mine.

This aura is far more powerful than that of the previous mining golem.

Roar.

A roar came from the darkness.

Immediately afterwards, a massive figure crashed through the rock wall deep inside the mine and appeared before Li Wu.

It was a giant mining golem that was over five meters tall.

Its body was cast from thicker black iron, covered with menacing rams and spikes.

Its arms are no longer pickaxes, but two huge drill bits, each over a meter in diameter, rotating at high speed on the left and right.

Above its head, a blood-red name stands out prominently.

【Mine Guardian - Destroyer (Elite Boss)】

[Level: LV30]

【HP: 35000】

Attack: 520

【Skill:???】

[Introduction: A former foreman in the mine, driven by his deepest obsession, voluntarily underwent transformation into a mechanical puppet, vowing to protect the mine for all eternity.]

"BOSS?"

Li Wu looked at the huge thing in front of him, and was more pleased than surprised.

I never expected there would be a boss hidden here!

"Command: Eliminate the intruder."

The sound of the Destroyer's machinery echoed through the mine.

Its enormous single eye locked onto Li Wu, and the eight traitorous mining golems behind him.

The next second, the huge drill on its right arm, with a piercing roar, slammed into Li Wu!
