Chapter 254 – Wisdom’s Limit! Eighth Official Livestream (2)

Tear!

Accompanied by the sound of tape tearing, the five-meter-long red seal separated from the box . Chen Yu then threw the tape into the air at an altitude of 3,400 meters .

To let the audience have a clear view, he stepped aside and stood on the delivery box’s left . He then faced the camera and slowly opened the box’s left cover, revealing a light blue cylinder inside .

Immediately afterward, Chen Yu moved to the right and opened the right cover . Finally, the product’s full appearance entered the eyes of both Chen Yu and the livestream’s 20 million-plus viewers .

[Dammit! A cannon?]

[This cannon doesn’t seem very smart . ]

[It kinda looks like Dongfeng Express!][1]

[Maybe it’s a nuclear missile launch pad . ]

[It’s definitely an electromagnetic cannon!]

[It’s clearly a planetary engine…]

[UP, if you’re so incredible, do you dare host a livestream in the Forbidden City on Monday?]

“Hmm…”

Taking five steps back, Chen Yu carefully observed the blue cylinder and frowned .

Similar to his audience, if he judged the product based solely on its appearance, he couldn’t recognize what it was .

“Come and help me,” Chen Yu said as he hooked his finger at Little Peach . The two of them then quickly separated the product from the delivery box .

“Hu…”

Tossing away the box, Chen Yu had the camera capture a 360-degree view of the cylinder . However, even after thoroughly inspecting it, he still couldn’t figure out what it was for .

“The unboxing session is over . I believe that, like myself, everyone shouldn’t be able to tell what it is . From the Interstellar Portal to the Weather Control Module, to the Super Floating Castle, the further into the future a product came from, the more unimaginable it would be . ”

Reaching out, Chen Yu grabbed a card from the card slot located on the cylinder’s right side . “Fortunately, there is an instruction manual to help ‘ignorant’ ancient people like ourselves unveil this product’s mysteries . ”

After saying so, Chen Yu skillfully toggled the card’s power switch and carefully read the introduction that appeared .

“What?”

Chen Yu couldn’t help but exclaim in surprise the moment he saw the product’s name . Immediately, he accelerated his reading speed . And as his understanding grew, his surprise became shock, and his shock became admiration . Simultaneously, he also continually mumbled to himself .

“How magical…

“How beautiful…

“Unbelievable…

“Amazing!

As this card didn’t come with a projection ability, only Chen Yu could see its contents . Meanwhile, the livestream’s viewers could only watch anxiously while spamming bullet comments .

After giving his audience the cold shoulder for over a dozen minutes, Chen Yu placed down the card and faced the camera . He then sighed and said, “It’s too magical . Just how willful of a designer is required to create such a product?

“Everyone, do you know what this product is used for?”

[If you don’t say it, how the heck would we know?!]

[Dammit! You’re definitely doing this on purpose!]

[The cameraman is slacking today . ]

[Stop teasing us already!]

[I don’t know what you guys are talking about . I just came to see the female assistant . ]

[I’m also here to see the female assistant . I can’t believe you guys can get so excited over a big metal rod . ]

[I’ve checked every broadcasting platform . The total viewer count is already over 20 million! Doesn’t anyone need to go to work or school?]

Storing the instruction card into his pocket, Chen Yu stroked the cylinder’s smooth surface while organizing his thoughts . He then said, “It’ll be difficult to explain this product in just one or two sentences . It involves a lot of astronomy, chemistry, physics, and aerospace knowledge .

“That’s right . This is an aerospace product . It is something that nobody has ever thought about, even in 2020 . Of the previously revealed products, all of them have once been described by scientists, novelists, or various cultures . There is theoretical support for every one of these products .

“However, this thing…” Patting the metal cylinder, Chen Yu continued, “It doesn’t exist in modern human history . At least, I haven’t heard of anyone or any artistic work describing this product before . ”

After a slight pause, Chen Yu straightened his back and recalled the knowledge he had learned over the past few weeks . He then loudly said, “Now that the unboxing session is over, let’s proceed with the introduction session . I’ll try my best to use concise language to introduce this magical and absurd product to everyone .

“First of all, there are only two ways for humans to enter space .

“The first method is through rocket propulsion . The second method is through spacecraft . However, as the latter requires the propulsion of rockets, strictly speaking, humans can only enter space through rocket propulsion .

“However, due to the high cost of rocket propulsion, the scientific community has always sought a more efficient method to enter space . Meanwhile, the most famous and feasible method thought of was the space elevator . ”

After saying so, Chen Yu stretched out a finger . “Before I introduce the space elevator, I have to first mention a person . Russia’s

Konstantin Tsiolkovsky . I’m sure most of the audience . However, I’m sure you must’ve heard his nickname before .

“The Father of Rocketry!

“The quote “the Earth is the cradle of humanity, but one doesn’t always live in the cradle” originated from this person .

“Tsiolkovsky was born in 1857, a time where airplanes didn’t even exist yet . However, in that time where humans hadn’t even studied how to fly in the air, Tsiolkovsky had already started researching how to fly into space and enter the universe .

“He saw that a punctured balloon would be blown away by the air current and understood the principles of reaction force . Immediately, he created the rocket propulsion principle and devised a systematic calculation for it . One of the formulas Tsiolkovsky developed was also named after himself, and that is the Tsiolkovsky rocket equation .

“V=V0xLn (m0/m1) .

“This rocket velocity formula is easy to derive . It can be calculated using only a little calculus, so I won’t delay the program for this simple problem . ”

[Ah! My eyes!]

[Show-off!]

[I can feel the ridicule of an intellectual . ]

[My mom asked me why I’m trying to jump into the toilet while watching a video…]

[Art students say that you’ve made grammatical errors . :)]

Straightening his mask, Chen Yu continued, “According to the formula, to enter space, the propulsion required is massive . Hence, the mass ratio of m0/m1 must also be large . m0 is the rocket’s mass with propellant, and m1 is the rocket’s mass without propellant . The ratio of the two must be large . What does it mean?”

[I don’t know . ]

[I don’t know . +1]

[I can understand every sentence you’re saying, yet I can’t understand what you’re saying at all . ]

[I understand everything, yet also don’t understand anything…]

[Awesome, awesome…]

After a slight pause, Chen Yu smiled and said, “It means that the fuel’s mass must be great . Therefore, most of the rocket’s mass consists of fuel . Even to this day, this fact remains unchanging . This is also the reason why space operations are so costly . They simply waste too much fuel .

“Meanwhile, after completing the rocket equation, Tsiolkovsky went a step further and specified the use of liquid fuel, and then created the multi-stage rocket principle . By the time he completed this series of great works, humanity still didn’t even know how to build airplanes .

“Some viewers may want to ask, what is Tsiolkovsky’s relationship with the space elevator? Why must I focus on introducing him?

“Because this great person is also the person to have proposed the space elevator theory . He had even completed all the relevant theories and calculations, including the structural strength of the material required, the height of the space elevator, the counterweight ratio, the balance point of 36,000 kilometers, etc . To put it simply, so long as the material requirement was met, humanity would be able to construct a space elevator by relying on the Father of Rocketry’s legacy .

“This isn’t a delusion! In 2019, Japan and China had already produced qualified materials and had begun the space elevator construction plan . By 2050 at the latest, the project will be fully launched, and everyone would get to see the space elevator within their lifetime .

“But…”

Stretching out his hand and lightly patting the metal cylinder beside him, Chen Yu said, “With this thing, we can abandon the space elevator project . We won’t need to wait until 2050 . With modern human technology, we already have the basis for constructing this product .

“The only thing limiting its birth is the scientific community’s imagination .

“And this product’s name is called…

“The Earth Spray!”
