Alarm bells rang out in the headquarters, and red dots kept appearing on the projected map, and they were spreading.

"There is a biochemical reaction in Area 13!"

"The Joint Research Center is missing!"

Everywhere there were urgent alarms, and the woman in the center of the command room wore a marshal's shawl and looked calm.

Jin Ge, Marshal of the Defender Mercenary Company, is also one of the commanders of the Resistance Front, a woman alongside the Iron Horseman.

"The localities acted according to the plan until the message of the 'apostles' was captured."

In the lounge downstairs of the command room, Team X was still resting.

Sakura felt in her pocket and pulled out a piece of gum. Take out a slice and peel it and stuff it into your mouth, then hand it to Zero and Aoi.

Aoi pointed to the gas mask on her mouth.

"You ......" Sakura was stunned for a moment.

Sakura remembers that Aoi was hit by a claw from a biochemical ghost during the war, covering the lower part of her entire face, so she covered her mouth with a gas mask. But with the reset of time, the injuries suffered by everyone during that time should also be gone.

Sakura suddenly thought of something, and ripped off her clothes, and sure enough, she found a scar the size of a coin on her chest. Zero also lifted her clothes and looked at them, and found a tattoo with the names of several of her fallen comrades.

"What's going on?" Sakura was stunned for a moment.

"The world...... in recovery. "Zero's look is hard to understand.

……

The changes that have taken place in this world have basically been noticed by everyone, and this change has also been informed to Su Sheng and others.

Liu Ying looked at Su Sheng with an inquiring eye, and Su Sheng replied after thinking for a while, "I'm not sure, after all, it's the first time I've entered the Fragmented World of the Peculiar Point." However, combined with the information I learned from Tianqing, plus my previous experience in some fragmented worlds, it is about ...... It should be a self-tripping operator dislocation and a multidimensional Hilbert space...... Belch...... So what...... What's going on? ”

Su Sheng laughed awkwardly, and then said, "I can't remember this kind of thing clearly, anyway, this fragment is connected to another dimension for some reason, and then it also involves the quantum timeline or something." ”

"I'm completely confused." Liu Wei said with some dissatisfaction.

Shu Yiguang logged into the network of the headquarters and said to Su Sheng while typing: "Mr. Deceased, please repeat those keywords again, maybe we can find some clues in the database." ”

"yes, the basic tech tree is still common." Liu Wei glanced at Su Sheng as he spoke.

"First of all, Hilbert Space ......," Su Sheng said a word.

After searching for it, Shu Yiguang quickly said: "I have found about thirty materials, and according to the results of the library test of the dice of fate, I think this paper from Doctor.Zeng is the most suitable for our understanding - the so-called Hilbert space is such an abstract space, in which there are vectors that can be used to describe the states of the system in quantum mechanics, and these vectors must have a positive definite inner product, that is, the probability of these states is not negative; In this space there are Hermitian operators, which represent observable measurements; THERE ARE UNITARY OPERATIONS IN THIS SPACE, WHICH CORRESPOND TO ROTATIONAL OPERATIONS IN THREE-DIMENSIONAL SPACE, REPRESENTING THOSE OPERATIONS THAT KEEP THE PROBABILITY OF THE STATE CONSTANT......"

Liu Ying, Su Sheng and Su Li: "......"

"In Hilbert space, the evolution of the state vector over time is called 'painting', and the coordinate system that describes the state vector is the representation...... (balabala) finite-dimensional, which can also be infinite-dimensional...... The eigenvalues of (balabala) are discrete spectra, and the eigenvalues of uncountable dimensional representations are continuum...... Schrödinger equation ......"

Liu Wei waved his hand, covered his forehead and said, "Okay, stop, I've given up on understanding this kind of thing." ”

"So those guys on the science side are perverts." Su Sheng sighed.

"It would be nice if Tianqing was still here, compared to the scientific side of Tianqing, you don't think it's reliable to look at it." Liu Ying said again.

The ability on the scientific side constantly analyzes and strengthens his abilities through scientific theories, doctrines, hypotheses, theorems and various equations, for example, there is a personal ability similar to a super electromagnetic cannon, and when he explains his ability enhancement experience to his disciples, he takes a bite of complex things such as Gaussian kernel functions and support vector machine principles, and the Hilbert space that has just made Su Sheng and them retreat is also one of the problems he explained.

If Su Sheng remembered correctly, the man's tone was like this......

"Hilbert space is actually very easy to understand, and it is already clear from the definition!"

It was as if Hilbert space and trigonometric functions were a difficult thing.

Although Su Sheng's friends from the mathematics department said that it was indeed a difficult thing with trigonometric functions, Su Sheng said that I don't listen, I don't listen.

Su Sheng was born in the Department of Civil Engineering, and originally he thought that it was already a very complicated thing to calculate the repayment of principal and interest in economics and the amount of steel bars in construction, but after the end of the world, the professionals on the scientific side still refreshed his three views.

At this time, Su Li got down to business: "But it doesn't matter if you don't understand, we just need to understand what situation we are facing now." ”

Everyone looked at Su Sheng together, and Su Sheng had no choice but to say: "I just have a guess now, these changes may be related to the coming apostle, and that apostle may be related to this world, so his arrival triggered a series of changes, which led to the recovery of this world." ”

"And what about the impact?" Liu Zhen asked.

"The power of the natives of this world will be greatly enhanced, or recovered, but correspondingly, the miscellaneous soldiers we face will also become very strong."

"In other words, similar to the level of the scene in the game? Allies and enemies are all upgraded, so that our role will be smaller? Su Li said.

Su Sheng nodded: "That's right, but the strength of the apostle is constant, that is, the difficulty of our final battle has not changed." And I speculate that in a high-level world, our strength will also increase faster than before! ”

Liu Ying thought for a while and looked at Su Li: "But this promotion is probably limited to us, I rely on transformation cards, the dead rely on prop points, not to mention the dice, and now the most obvious impact here should be the red dragon you." ”

When Su Li heard this, she immediately activated her abilities, and a golden mechanical cloud spread out from the surface of her body, forming a shield composed of various mechanical parts.

This is a mechanical creature that Su Sheng told her - the Holy Mother of Protection.

Su Li felt it for a moment and said, "The speed of construction is faster, and the mechanical clouds are more tightly combined. If you keep training the use of abilities in this world, I estimate that the progress will be faster than outside...... About thirty times. ”

"It's a mixed blessing." Liu Wei made a summary.

"However, the focus is still on how to deal with that apostle, and the priority now is to obtain information about that apostle."

"This one is not in a hurry." Su Sheng looked in the direction of the command room, "For the time being, trust the aborigines here." ”
