Chapter 623: The importance of oxygen!

Can the earth fall into dead silence in five seconds?
can!
The earth loses oxygen for one second, and any buildings constructed with concrete will collapse suddenly, because oxygen is a special binder for concrete. Once it loses it, high-rise buildings will instantly crumble into muck.
If the earth loses oxygen for two seconds, the ozone layer, which can resist ultraviolet rays, disappears completely. A large amount of harmful solar radiation will reach the surface. In that case, human beings cannot survive under the sun.
When the earth loses oxygen for three seconds, the atmospheric pressure begins to change drastically, and it will drop by about 21%, which is equivalent to the pressure of about two kilometers at sea level. Since the human body simply does not have enough time to adapt to this change, it will It causes the inner ear tympanic membrane to explode and directly loses hearing!
The earth loses oxygen for four seconds, and the sky will gradually darken due to the reduction of reflectors in the air, and the entire water will begin to sink into darkness. Not only that, but all power is lost, and any non-electric transportation method will be completely Paralysis, such as: the plane will fall directly...
If the earth loses oxygen for five seconds, the crust composed of 48% oxygen will completely collapse. Everyone and things on the surface of the earth's crust will be under the weight of dust and fall to the core of the earth one after another!
In just a short period of five seconds, everything on the earth ceased to exist. This shows how important oxygen is to humans!
Now that he knew the answer, Su Mo opened his eyes and started the journey of searching for the oxygen element. Soon, he found the most important element for mankind in an inconspicuous corner!
Su Mo lightly tapped with his hand, and the oxygen element light spot was placed on his finger, and he slowly said: "Find the oxygen element!"
Simple, direct, and confident!
"Congratulations, it took four minutes and fifteen seconds!"
Hearing this voice, Su Mo showed a smile on his face.
Five floors!
Not far from the tenth floor!
At this moment, Su Mo has an intuition that the tenth floor will surely surprise himself!
Although he doesn't know why he has this intuition, Su Mo firmly believes that everything has a cause and an effect!
No one has been on the tenth floor?
That was before!
It will be available from today!
Others are others, he is him!
Because he is Su Mo!
"Crack—"
The metal chamber slowly rises to the sixth floor...
...
When it was used, the fifth-tier assessment results appeared on the screen outside the holy tower.
"On the sixteenth, it takes four minutes and fifteen seconds!"
The historical list appears.
First place: Nine minutes and 43 seconds!
Second place: Eleven minutes and fifty-nine seconds!
Third place: 15 minutes and three seconds!
The white light flashed, and the new historical list appeared in front of everyone.
First place: Four minutes and fifteen seconds!
Second place: Nine minutes and 43 seconds!
Third place: Eleven minutes and fifty-nine seconds!
Top of the list!
Still the top!
The first five levels, four tops, one second place!
"What is this going to do?"
"Four tops..."
"Horror, terrible! This will not leave us alive at all!"
"It seems that there has been no ranking since the sixth floor. The top five rankings, Su Mo alone accounted for four. This..."
Although Su Mo is already a fifth-level mathematician, some people are jealous, and many people are not convinced from the bottom of their hearts.
Why can an 18-year-old student become a legendary existence of a fifth-level mathematician?
luck!
It must be luck!
Although this idea is ridiculous, it is real!
And there are not a few people who have this kind of thought. It doesn't need reason to be jealous of someone!
However, seeing Su Mo Santa’s assessment results today, I woke up a lot of people who were jealous of him, the top five, four tops, and one second!

This result is not acceptable if you are not convinced!
Because they can't do...
In their eyes, breaking a record is as difficult as reaching the sky, let alone being like Su Mo...
Not only that, everyone knows that this is the first time Su Mo has entered the holy tower.
On the sixth floor for the first time?
Too shocking!
The same people, why is the gap so big?
It shouldn't be!
Cough
Claude looked at Noel with a weird look, "The first five floors have passed, and I can finally be quiet for a while!"
"Yes!"
Noel gave a wry smile. He knew the meaning of Claude's words. Only the first five floors of the Santa had a historical list, and they disappeared from the sixth floor.
However, starting from the sixth floor, the difficulty of the assessment began to rise geometrically. Those who entered the holy tower for the first time, no matter how talented they were, would not be able to pass the assessment on the sixth floor!
Because no one has ever done it!
Nikola Tesla is genius enough, right?
Even if it was him, he was stuck on the sixth floor when he entered the holy tower for the first time, and only passed the evaluation on the sixth floor when he entered the holy tower for the second time. This shows how difficult the evaluation on the sixth floor is!
It is not on the same level as the first five floors!
National National Taiwan University.
Li Tong turned his head and glanced at Yan Jiuxi, his eyes filled with curiosity, "Classmate Yan Jiuxi, how many floors do you think Su Mo can ascend to the holy tower this time?"
Regarding the information about the Sacred Tower, Li Tong has checked some information on the Internet these days. Under Noel's side-knack, he learned some unknown things. He knew that the Sacred Tower started on the sixth floor, and the difficulty began. Rising dramatically, no one can pass the sixth floor in one pass!
there has never been!
"Teacher Li, what do you think?" Yan Jiuxi smiled softly before asking softly.
"I think Su Mo is either stuck on the sixth floor or on the seventh floor."
Li Tong hesitated for a moment and said what he thought, "Anyway, I don't think Su Mo can be on the eighth floor. This is the first time he has entered the holy tower. It is already very good to achieve such results!"
Although no one can pass the sixth-level assessment in one go, this person is Su Mo after all!
Anything about Su Mo cannot be theorized in general. Li Tong is very clear about this!
Therefore, Li Tong believes that Su Mo has a great chance of passing the sixth level assessment, but there is no hope for the seventh level!
Li Tong also hoped that Su Mo could create miracles, but he had to seek truth from facts!
"My opinion is slightly different from that of Teacher Li."
After listening to Li Tong's opinion, Yan Jiuxi smiled lightly, looked at the sixth floor of the holy tower with beautiful eyes, and whispered, "I think Xiaomo can make it to the tenth floor!"
"The... tenth floor?"
The corners of Li Tong's mouth twitched slightly, and he couldn't help but muttered, "Although you are young couples, you can't be so blindly confident, right?"
The tenth floor?
impossible!
Ascend to the tenth floor when entering the holy tower for the first time?
In Li Tong's view, this is completely nonsense!
"This is a little... unlikely, right?"
Because Yan Jiuxi is a girl, Li Tong said this more tactfully. If Yan Jiuxi was a boy, he would directly say, "It's better to be awake during the day!"
"I know that Teacher Li must be very skeptical of what I said just now."
Yan Jiuxi chuckled softly, and there was a glimmer of admiration for Su Mo flashed in his eyes, "But I just believe that Xiao Mo can reach the tenth floor, and I believe it for no reason!"
In order to get the quota of the Holy Tower, Su Mo struggled. Yan Jiuxi knew this very well, and she also knew that Su Mo had been trying to figure out the operation mechanism of the Holy Tower.
If you want to figure it out, you must go to the tenth floor!
With Su Mo's character, it is impossible to give up this opportunity, because this opportunity is the only one!
But whatever Su Mo wants to accomplish, he can definitely do it!
Even if people all over the world don't believe in Su Mo, she, Yan Jiuxi, will believe it!
Li Tong shook his head and laughed. Although he didn't agree with Yan Jiuxi's words in his heart, he couldn't refute it.
"Then let us wait and see!"
