Not long after Lin Xi returned to his apartment, there was another knock on his door.

When the door was opened, the people outside the door were wearing the white lab coats characteristic of the staff of the institute.

This time, the news from the researcher was much simpler than the invitation from the military, with only four words that were clear at a glance:

The director has please.

Needless to say, the director is Zhu Shiqiu.

"Okay, please wait a moment, we'll be there shortly."

Lin Xi knew that as a member of the research institute, the old man was really good to them, so he didn't put on any show for this de facto colleague, but replied very politely.

However, this researcher, it seems that he has rarely dealt with people for a long time, with a wooden nerd expression, he doesn't understand human feelings, except for when he first saw Wu Qiuli, his eyes lit up, and he had an absent-minded expression at all times, not knowing what he was thinking, even if he was facing Lin Xi's politeness now, he just nodded briefly, even if he responded.

However, Lin Xi is not angry, although he has slowly begun to adapt to his status, but in his bones, the approachability of the character of the little fart is still there.

On the contrary, he was very curious about Zhu Shiqiu's purpose for inviting him at this time.

You know, the institute has just experienced a catastrophe, and his beloved apprentices are still lying in the operating room to be rescued, no matter what, this does not seem to be a good time to meet guests.

It's just that since the host has placed an invitation, he can't question anything anymore.

After just tidying up a little, he called Wu Qiuli and the others, and under the leadership of the researcher, went straight to the area where Zhu Shiqiu was.

Soon, when Lin Xi and the others arrived in a hurry, they saw Zhu Shiqiu in the research room where there had just exploded.

The scene of the explosion was apparently only hastily organized:

The air was filled with the smell of gunpowder smoke left after the explosion, mixed with the smell of chemical reagent crushing and evaporating, and the smell was very pungent; In many corners and crevices of the room, there are still glass slags and metal debris that have not been cleaned; In the middle of the research room, there were still a few splashes of black and red blood, probably only smeared a few times, but they were not scrubbed, and when looked at from a distance, it looked extremely dazzling.

I think it was the researchers who died who left behind.

In the middle of this mess, Lin Xi saw Zhu Shiqiu at a glance.

It's just that this high-ranking professor is not in the mood to do any experiments at this time, and he is not as crazy as usual, but just like an ordinary old man in his last years, full of pain.

He held the damaged test bench with one hand and covered his face with the other, his short, thin back exuding a strong air of pathos.

This is also because the old man was born in a civilian position, and he has been rolling in the laboratory all his life, and he has not seen too many life and death, otherwise if there were battlefield warriors like Eric and Mongolia standing here, then they must not be so sad about the death of their subordinates.

But because of this, Lin Xi felt closer to him.

"Professor."

Lin Xi cautiously walked a few steps, bypassed the blood stains on the ground, and whispered behind Zhu Shiqiu.

"Oh, you're here."

Zhu Shiqiu's shoulders trembled, as if he was suddenly awakened from grief by Lin Xi's soft cry.

He first looked left and right blankly, and then came back to his senses completely, pointing to the table next to him that was not completely broken, "You sit, you sit." ”

Lin Xi pulled Wu Qiuli to sit down as she said.

Little Apple sat in Lin Xi's arms, while the Wind King, Xia Qianzhu and the others stood obediently behind them.

Now, in their small group, they have gradually and spontaneously formed their own order, Lin Xi's strength and sincerity, Wu Qiuli's wisdom and beauty, and Little Apple's potential and cuteness, make them the three well-deserved cores of the team, as for the others, for the time being, they can only accompany the last seat.

After hastily dividing the guests and hosts, Lin Xi opened his mouth, and was about to ask Zhu Shiqiu what was the matter with calling them, but the old man had already taken the lead and went straight to the point, "I called you here today, just to ask if you have any questions, if so, I can answer them all for you." ”

Lin Xi was stunned.

In the last days of the world, if he didn't have a bunch of problems in his heart, it was all fake.

It's just that when he was still brewing, Wu Qiuli had already reacted first, and asked rhetorically, "Is any question okay?" ”

The old man nodded, "Any question is fine." ”

"So, what is that cloud?"

The girl's question goes straight to the core, and the first question is placed on the root of the apocalypse.

"I don't know." The old man shook his head.

Well, the first question is not known.

"Don't know?" Lin Xi raised his voice in surprise, "You should always know the composition of that cloud, right?" What caused this disaster? ”

"No constituents, no substances."

Old Man Zhu's cloudy eyes became extremely deep at this moment, and he stared at Lin Xi and said, "You know what I mean, right?" The cloud doesn't actually exist, it just looks like a cloud, but it's actually a high-energy reaction that doesn't mix anything with matter, and the energy density is ...... Hmm, I want to think about ......."

He took out an old-fashioned calculator from the pocket of his white coat and pressed it a few times before saying, "If you use an intuitive metaphor to explain, then the energy condensed every time that dark cloud appears is about equivalent to all the energy released by a magnitude 9 earthquake. ”

Hiss.

Lin Xi gasped.

When he was in middle school, geography and history were not bad, so he naturally knew that a magnitude 9 earthquake was almost the highest magnitude that could be achieved in reality, and the Wenchuan earthquake caused nearly 100,000 huge casualties, but it was only magnitude 8, and it was already a terrifying natural disaster of the land sinking type; As for the Hiroshima atomic bomb, it destroyed all life within a radius of 16 kilometers and killed hundreds of thousands of people, directly or indirectly.

And the cloud of death, every time it appears, it consumes almost a huge amount of energy.

Every day, countless clouds of death come and go over the world, and the amount of energy consumed is simply astronomical.

However, as long as he thought about the great changes it had caused to this world, Lin Xi was suddenly relieved in his heart.

Seriously, not to mention 12,000 atomic bombs, even if they are 1.2 million, 12 million, or 120 million, I am afraid that there is no way to bring the whole world into a new era like now.

He thought to himself with some sourness.
