Li Ke took a backpack from another person. Although the backpack looked somewhat small, its craftsmanship was rather crude, being an experimental product after all.
There was an opening at the bottom of the backpack, and he inserted the "Legs Play Years No. 6" battery he was holding.
After closing the lid, he skillfully put it on his back.
He glanced at Li Shimin, then at Cheng Yaojin and Li Xiaogong, and then asked with a smile.
"Father, Uncle Cheng, Uncle Nine, you should all have weapons on you, right?"
"Your Highness the Prince of Han, you jest. When one ventures out, especially when accompanying the Emperor, how can one not carry something for self-defense?"
Cheng Yaojin patted his waist twice. It bulged, clearly indicating he had a firearm tucked there.
Zhang Gongjin, Yuchi Jingde, Li Xiaogong, Chai Shao, and Qin Qiong were all the same.
Li Ke smiled again: "Father, then your son shall begin."
As he spoke, he reached out and tapped the strap on his shoulder, where a black button was located.
In an instant, a magnetic field spread out, silently!
The next moment, everyone present swayed uncontrollably.
In addition, all iron and lead objects in the office flew out with clanging sounds, smashing hard against the walls.
Everyone was stunned.
"Damn it, what's going on!"
Li Shimin was in disarray. That sudden surge almost sent him tumbling off his chair!
It felt as if someone had shoved him hard!
Others felt the same, but Cheng Yaojin reacted the most dramatically.
He turned ashen-faced, clutching his groin and squatting down: "Damn, it hurts, it hurts..."
Yuchi Jingde quickly asked, "Your Highness the Prince of Han, what exactly is going on!"
Li Ke pointed to the backpack behind him and explained, "Of course, it's the effect of this anti-magnetic backpack."
"Once this thing is activated, all iron and lead objects within a ten-meter radius will be repelled!"
"Of course, if it were a large iron block, then I would be the one flying out."
Li Shimin: ...
What the hell!
His eyes sparkled as he stared at Li Ke.
"Treasure!"
"This is a great treasure, hahahaha!"
Li Ke felt a bit shy under his gaze and was about to modestly decline when Li Shimin continued.
"Don't misunderstand, what I'm referring to is this anti-magnetic backpack!"
Li Ke: ...
Fine, he hadn't known this father for just a day or two; his son knew his character all too well.
He then proceeded to explain how to use the backpack.
"Father, uncles, the usage of this thing is very simple."
"The left shoulder activates the magnetic field, and the right shoulder deactivates it."
"The battery is installed at the bottom of the backpack."
"The only thing to be mindful of is that when using this, one must not carry any objects made of iron, copper, or lead."
"That's not right. I heard from An Zhi that the human body also contains iron in its blood, which is why eating iron-rich foods can replenish blood. If what you said is true, why didn't the iron in your body fly out?"
Qin Qiong was a little confused. He had suffered from poor hematopoietic function and severe anemia. These were things that Fang Er had told him during his recovery period at Fang Family Manor, where he received blood transfusions.
Li Ke explained, "That's because the form of iron is different."
"The iron content in blood is the content of Fe ions bound within hemoglobin; it exists in the form of chelated ions. The iron in steel, on the other hand, is composed of solid iron compounds, including iron, iron oxides, and so on."
Everyone: ...
Bloody hell, they didn't understand a word!
Was that supposed to be an explanation?
But it didn't matter, as long as they knew that this thing had no effect on the human body!
Cheng Yaojin was still squatting on the ground, gasping in pain and staring resentfully at Li Ke.
"Your Highness the Prince of Han, the next time you demonstrate something, can you give us a heads-up first!"
"My balls almost got smashed by the gun!!"
Li Shimin was stunned for a moment, then he understood and slammed the table, bursting into laughter.
"Hahahaha!"
"I was just wondering what was wrong with you!"
"You almost suffered a complete catastrophe!"
"How about it, would you like to invite someone over to examine you?"
"Yes!"
Cheng Yaojin nodded vigorously, greatly concerned that his future happiness might be lost from then on!
Motorola, being quick-witted, ran out to call for someone. He felt immense pressure staying with these fellows!
"Is it troublesome to manufacture this backpack?" Li Shimin's expression became serious as he asked about this.
Li Ke replied, "Troublesome! Extremely troublesome! We need to dismantle the gold dredging ships!"
"Each backpack requires a piece of crystal magnet as a magnetic source, and it also needs to be cut. The success rate is only sixty percent. If it fails, the crystal magnet is considered scrapped."
Li Shimin waved his hand dismissively: "These are not problems! If An Zhi can procure thousands of gold dredging ships, then this thing is probably not a rare item. Just dismantle them!"
"In any case, within five days, produce three hundred backpacks for me!"
"Wait a moment!"
He suddenly stopped and then looked at Wang Xuance and then at his son.
"What is a gold dredging ship, and what is it used for?"
He had never witnessed the process of gold dredging ships mining gold, nor had Fang Er explained it to him.
Among those present, besides Li Ke and Wang Xuance, only Li Xiaogong and Chai Shao had personally seen it!
But this matter...
Li Xiaogong had never mentioned it to Li Shimin!
When Fang Er dumped thirty gold bricks into his residence, he decisively chose to keep silent...
Therefore, when Li Shimin asked about this, he feigned ignorance.
I don't know, don't ask me!
As for Chai Shao...
Regarding anything related to Fang Er, he needed to seek instructions from Li Xiuning.
Only after the lady's approval would he dare to spread the word, otherwise...
Those who understand, understand!
The consequences would be far worse than just whips and candles!
Li Ke scratched his head. His brother-in-law and his father, who was more important? This seemed like a question that didn't need consideration...
"Father, that thing can mine gold, and it's extremely fast!"
"As long as a gold mine is found, one gold dredging ship can mine a gold brick weighing four thousand seven hundred taels in just ten minutes!"
"Bang!"
Li Shimin directly slammed the table and stood up: "What!"
He who had just said to dismantle them freely now regretted it immensely!
This thing was a goose that laid golden eggs!
Dismantling even one pained him!
But then he thought of Fang Er, who was seeking medical treatment on the other side of the passage, and that incredibly powerful...
"Dismantle!"
Li Xiaogong: ...
Looking at the expression on that fellow's face, it was more pained than that of the Ninth Master!
The gold dredging ship isn't yours, so why are you in pain?
Oh?
Speaking of which, why was the Ninth Master pained just now?
