I painted an aircraft carrier on the courtyard house for Dongda University.

When he reappeared, he was standing in front of a massive museum. Because he was invisible, he was like an invisible ghost, and no one noticed him.

He first activated his senses to carefully survey his surroundings, and only after confirming that there was no danger did he slip into the building.

His gaze instantly locked onto the mother-of-pearl inlaid rosewood five-stringed pipa, a flash of hatred crossing his eyes.

Immediately afterwards, with his silent flashing, the items inside the building disappeared one by one.

When the last Japanese king's gold seal was taken away, the entire building was instantly filled with colorful fireworks shimmering with a brass hue.

Just as he was about to leave, he suddenly had the urge to sense his surroundings again.

Suddenly, a strange sensation was detected at the edge of their senses. Upon closer inspection, they discovered a peculiar space deep underground behind the building.

He slipped into the basement and activated his senses; the sight before him left him utterly shocked.

This place is actually a huge underground library with three underground floors, and the main entrance consists of three vault doors.

Surrounded by various ancient books, the entire basement resembled an archive, with bookshelves piled high with books.

Zhou Weiguo casually pulled out a book from the front row, which turned out to be the Siku Quanshu (Complete Library of the Four Treasuries).

Looking around, the three underground floors are mostly filled with ancient books from the Xia Kingdom.

Moving to the second floor, there are still ancient books, but this floor stores documents from other countries.

Upon reaching the first floor, one finds it filled with books from Xiao Rizi's own country, the handwriting messy and resembling scribbles.

Zhou Weiguo strolled around leisurely when suddenly, a huge bookshelf came into view, appearing quite out of place.

Curious, he walked over and saw the books on the bookshelf. He was shocked and felt a strong tremor in his heart.

He stared intently at the "Water Supply Department Diary," then looked at the rows of heavy books beside him, pulled one out, and found it contained a series of photographs.

The contents of the photo made his pupils shrink. Looking at the photo album on the bookshelf with the time and location marked, Zhou Weiguo could no longer suppress his emotions.

As his figure flickered, the entire basement became empty, even the bookshelves disappeared.

Half an hour later, standing two kilometers away and watching the two loud bangs, Zhou Weiguo squinted at the sky that had been dyed red, and said with a smirk, "No need to thank me. I know you guys love setting off fireworks everywhere, right?"

Looking at the "big fireworks" of Xiao Ri in the distance, Zhou Wei felt an unprecedented sense of joy.

After pausing to admire the view for a moment, he slipped into the building behind him.

About ten minutes later, he reappeared, muttering, "They're so stingy! Such a big branch, and only 23 tons? Who would believe that? Why bother with all this unnecessary stuff!"

Just as he was about to leave, a stone tablet suddenly caught his eye.

I glanced at it subconsciously, and instantly froze on the spot.

I didn't really understand most of the text on the stone tablet, but the lines "The main building was built in 1896, Building No. 1 in 1932, Building No. 2 in 1935, and Building No. 3 in 1938" are deeply etched in my mind.

An uncontrollable rage rose in his heart. The main hall was established in 1896, and the following decades were peaceful, but it was in 1932, 1935, and 1938, the years when the country was at war with Xia, that it was continuously expanded.

He cursed inwardly, "I wonder if these people are truly clever or just pretending. They've already done it, and now they have to write it all down and post it here?"

Zhou Weiguo then observed the various fireworks in the space and found that the rest were all low-powered, which made him worry.

At that moment, the system's voice, clearly suppressing anger, rang in his mind: "Temporary skill, 10000-meter radius perception and 10000-meter teleportation function activated, time limit 24 hours. 5 thermobaric bombs included. This time it's on me, you can continue."

Zhou Weiguo listened to the system's voice and felt a little strange. He asked in confusion, "Hey buddy, were you definitely invented by someone from China? You're a system, and your emotions are as volatile as mine!"

However, the system did not respond.

Seeing that the system ignored him, Zhou Weiguo shrugged and then activated his perception.

"Holy crap??? A tube... a tube? How many meters is a temporary skill exactly?"

"A radius of 10,000 meters."

"Holy crap, I love you to death, buddy!"

"Host, there are 23 hours and 59 minutes left. If you don't want to waste time here, please act quickly."

Zhou Weiguo gave a thumbs up and said, "That makes sense."

................................

23 and a half hours later

"Brother, the house is full of animals, so I can only play in the vegetable garden now."

At this moment, Zhou Weiguo was covered in dust and grime, and was flashing back and forth in a bottomless place.

Hearing this, he continued working with his hands and quickly replied, "Daughter, please help me tidy up. Just hold on a little longer."

"Host, you're really ruthless. I'm starting to admire you."

Zhou Weiguo laughed and said, "You've finally been generous enough to give me such a great skill, I have to make the most of it."

"Host, your mining method will disrupt the stability of the land structure here."

"Uh? Dude, are you concerned about the stability here?"

"Dig as much as you can, dig as much as you can! But I have to warn you, you've already mined up almost all the rare earth minerals worth 5,000 to 10,000 ounces on the seabed of South Bird Island. Most importantly, your temporary skills Perception and Teleportation only last for 28 minutes, and your temporarily unlocked super-large temporary storage space, temporary invincibility, and temporary data analysis function will all need to be renewed for 2500 energy points in half an hour. Do you want to use 2500 energy points to renew for 12 hours?"

Zhou Weiguo's heart skipped a beat, and he tentatively asked, "That system, that ten-thousand-meter perception teleportation, can I renew my subscription? Speaking of which, these temporary skills of yours make me feel like a god, they're simply amazing! When can I directly possess these skills?"

Upon hearing this, the system seemed instantly enraged, immediately yelling, "Get lost! Get as far away as you can, and stop daydreaming! Unless it's a special circumstance, how could I possibly grant you 10,000-meter perception and teleportation? I was a bit impulsive back then; normally, it's only a hundred meters at most. As for the Invincible Golden Body, it has a limited number of uses. This skill is similar to the life-saving skill I gave you; you can use it three times a year. As for the temporary storage space and data analysis, you can use them anytime as long as you're willing to provide energy points."

Hearing this, Zhou Weiguo felt helpless.

If only the skill of 10,000-meter perception teleportation could be available forever, then as long as he activates his invincible golden body, he would definitely dig out all the mines underground, no, not only dig out the mines, but directly break the continental shelf!

At that time, all the men will be sent to the beautiful country, and all the women will be sent to the Xia country.

Just as he was lost in thought, the system continued, "Host, I need to remind you that if you do not renew your subscription in 27 minutes, not only will the temporary space and its supplies disappear, but you will also be in the deep sea at a depth of 10,000 meters. The moment your invincible golden body disappears, you will die instantly."
