Chapter 622: The most important element

"Senior sister, don't make jokes with me. In this regard...I don't understand very well." Yan Jiuxi's voice was very small, and a seductive blush appeared on her pretty face.
This amazing beauty can be said to be: Clouds want clothes and flowers, and spring breeze blows the threshold!
Not to mention boys, even the girls around were taken aback, and at the same time they understood one thing in their hearts.
what's up?
The gap between them and Yan Jiuxi!
Apart from other things, the gap in hardware alone is the difference between heaven and earth!
This alone, they will never catch up in their lives...
"School girl, you don't need to say, I already understand!" The girl who asked the question gave a wry smile.
What she said made Yan Jiuxi very puzzled. She didn't say anything, how could she understand?
What's this all about?
The girls from the National Tsing Hua University around have spoken out.
"School girl, if I am a man, I must chase you, how can you be so beautiful?"
"Although I am a woman, I have to admit that the school sister Yan Jiuxi is really beautiful!"
"Why don't you think about me?"
Yan Jiuxi: "..."
In this regard, she can only sigh in her heart: "Seniors are really relaxed!"
Although very shy, Yan Jiuxi nodded politely in response to these words of praise, and did not respond.
Li Tong said: "Okay, stop making trouble, continue to watch the assessment."
As soon as the voice fell, a white light flashed on the screen above the metal door, which was the result of the fourth floor.
Sixteenth: 19 seconds!
After Noel and Claude saw this scene, their faces couldn't help being dignified. Both of them were very clear about the content of the fourth level assessment.
Three words-sense of justice!
As long as you pass the fourth level, you can graduate from Gamel!
So in this last level, the content of the assessment is a sense of justice!
Because anyone who is full of justice can contribute his own strength to the society, but if there is no justice in his heart, no matter how talented the student is, he will not help human progress. On the contrary, he may use his talents to do some harm Thing!
Therefore, if he fails the fourth level test, Gameler will dismiss such students!
As the saying goes, to be a good person, to be a good person, to be a good person!
Be a righteous person!
It takes about ten minutes for ordinary people to pass through the fourth floor, but Su Mo only took nineteen seconds. This shows how strong Su Mo's sense of justice is!
The more this is the case, the more clearly Noel and Crowder know how low the possibility of recruiting Su Mo is. After all, if even the country is willing to betray a person, it is absolutely impossible to pass the fourth-level character test, Su Mo was able to pass the fourth-tier assessment so quickly, it was obvious that he was loyal to his beliefs and his cognition!
Under this circumstance, wanting to recruit Su Mo into the nationality of Oceania is tantamount to a dream!
Soon, the fourth-tier historical list appeared on the screen again, but this time Su Mo's results were not the first, but second.
First place: 15 seconds!
Second place: 73 seconds!
Third place: 124 seconds!
A white light flashed, and Su Mo's results appeared in the historical list.
First place: 15 seconds!
Second place: 19 seconds!
Third place: 73 seconds!
When the students of Gameler saw this scene, they couldn't help but breathe a sigh of relief. Although Su Mo broke the record, he is not the first in the history list anyway!
"Scared me to death! I thought Su Mo was number one again!"

"Finally not the first place!"
"The second in history...and it's amazing!"
"I thought Su Mo wanted to be the top of the four. That would be too scary!"
There was a sound of discussion on the National Tsing Hua University side.
"Huh? Not the first?"
"Did Santa make a mistake? Why did Junior Su Mo get second?"
"It's a pity, it was only four seconds away..."
"It's possible that student Su Mo released the water, but it was the first time he entered the holy tower and he didn't understand at all."
With these voices, Claude's eyelids jumped and he muttered to himself: "To dislike second place? Too much!"
"That's because they don't know who the first place is. Su Mo's achievement is already very good!" When it comes to this topic, Noel's eyes are quite complicated, and his eyes are full of pain.
Claude kept silent for a moment, he knew some of the secrets of this matter, this was the eternal pain in Noel's heart.
"Principal, I'm sorry, I didn't mean to mention..."
"It's okay, it's been so long. This is my debt and I need to bear it myself!" Noel waved his hand and interrupted Claude. After that happened, it became his taboo for a while, but It had been so long, and he slowly accepted it.
Noel sighed, and a beautiful image appeared in his mind...
...
"On the 16th, the fifth level of assessment will begin. From 10,000 elements, find the most important element to humans. The time limit is one hour!"
As soon as the voice fell, on the metal wall in front of Su Mo, there appeared countless kinds of sesame-sized light spots, densely packed, and people's scalp was numb.
Even Su Mo couldn't help but wonder after seeing these light spots.
Dare this element be smaller?
That is, he, I am afraid that other people will not be able to see clearly!
Because of the blessing of the dazzling eyes, Su Mo can still accept it. An hour is very ample for him, so he slowly observed the 10,000 elements on the wall.
"Chromium, hydrogen..."
After watching for a while, Su Mo simply gave up the observation. There are currently 118 elements known to mankind, of which 94 are believed to exist in the natural world of the earth. But starting with element 95, the remaining elements can basically only be synthesized artificially.
Except for these 118 elements, Su Mo didn't know the remaining elements at all. In this case, it would be just a waste of time for him to look further. The correct answer should be in these 118 elements.
The remaining elements should all be interference items given by the tower. Thinking about this, Su Mo's thoughts quickly turned.
What is the most important element for humans?
Someone will definitely say water!
Because if there is no water on the earth, then humans will soon perish. Water is indeed a very important existence for humans!
Su Mo does not deny this, but water is not a kind of element, because water is composed of hydrogen and oxygen.
Hydrogen, oxygen...
Oxygen?
Numerous thoughts flashed in his mind, and suddenly, Su Mo's eyes lit up, and the corners of his mouth couldn't help but slightly cocked. He knew the answer!
That's right, it's oxygen!
This element is one of the countless elements in the world known to mankind. It may be highly poisonous, but it can give life to all things. It participates in evolution, from the birth of life to the emergence of giant insects in the swamp, and it partners with it. Together, changed the whole world!
This element is oxygen!
But it was not until the 18th century AD that humans knew the existence of oxygen!
But oxygen is very important to humans!
If once there is no oxygen on the earth, let alone a minute, only five seconds, the earth will be dead.
Do not believe?
Can the earth fall into dead silence in five seconds?
