Cold ice can't break the water, and dead wood can meet spring again.

But at this moment, right behind me, countless tiger shields suddenly flew up, crashing into the huge sword one after another. The sword was about to fall when a tiger shield bounced off it, and then several more tiger shields slammed into the sword.

All hope is rekindled in this moment!! I smiled and yelled:

"On the battlefield, all the soldiers of the army obeyed the order!! Right now!!! Immediately!!! Run back to the front camp!! ”

I quickly turned around, and the Shu army camp in front of me was the hope in my eyes at this time!!

I ran hard, I saw the soldiers around me also running towards the Shu army camp in front of me, the sword behind me was hit by the tiger shield flying towards Yiling Pass one after another, so that the original attack rhythm was completely disrupted, and we just took advantage of this short time, ran to the Shu army camp.

I heard a loud sound behind me again, obviously the effect of those tiger shields had all disappeared, but I was already smiling on my face, and the Shu army camp in front of me was already close at hand.

"Cheng Yin!! Have you ever been injured? As soon as I returned to the camp, Lin Yun asked with concern.

"Cheng Yin, what you did just now is really too risky, if there are some mistakes, then your life will be really in danger." Professor Wu appreciated worriedly.

"That's it!! Are you really..."Cui Ligang wanted to say something reproachful, but stopped as soon as the words reached his mouth. "However, there are really yours, and you can still think of this way to turn the opponent's offensive into your own."

That's right, it was the fact that I saw that all the blades would fly towards Yiling Pass, and I thought of this seemingly extremely risky approach, using the flying tiger shield to block the sword's attack. It bought valuable time for the soldiers on the battlefield of Yiling Pass.

Either way, it's well worth the effort.

"Don't be too happy, you're just lucky, you win a war by luck." There was no smile on Professor Twie's face.

I looked at Professor Twilight's expression and didn't speak.

"Classmate Cheng Yin, due to the success of your tactics, although the three thousand infantry soldiers on the battlefield were somewhat damaged, they all returned to the camp." Professor Wu said happily.

I saw the 3,000 infantry soldiers who returned to the formation, and the stone in my heart finally landed smoothly, and I looked at the two people on the wall of Yiling Pass, not knowing what their mood was now.

However, although the attack on Yiling Pass was not successful, at least a lot of important information was obtained, and it cannot be said that there was no gain.

I looked at the blue sky in the sky, and it was so blue.

"The whole army returned to the camp !!" I yelled.

In this way, the third attack on Yiling Pass came to an end.

We walked on our way back to camp.

My mind was full of the figure of the mysterious man, and I suddenly had the feeling that I seemed to know the mysterious man, but I couldn't say why.

"Professor Wu, have you ever heard of quantum entanglement?" I asked Professor Wu, who was walking side by side with me, to explain my doubts.

"Of course, why did you suddenly ask about this?" When Professor Wu heard the words quantum entanglement, he suddenly flashed the light of wisdom, it seems that he has not used physics much during this time, and he suddenly heard a topic related to physics, Professor Wu was very happy.

[1] The idea that space-time is "made up" of bits or something else is contrary to the predictions of general relativity. The new view is that space-time is not fundamental, but "emerges" through the interaction of qubits. Scientists don't know exactly what these bits are made of and what information they contain. Interestingly, however, these questions did not bother scientists. "It's the relationships between the bits that matter" rather than the bits themselves, says Brian Swindle, a member of the IfQ project and a postdoctoral fellow at Stanford University, "These collective relationships are the source of the rich physical properties of the universe." The key here is not their constituent units, but the way in which they fit together. ”

The key to this combination could be a strange phenomenon known as quantum entanglement, an incredible correlation between two entangled particles, even if they are far apart, said Vijay Balasubramanian, a physicist at the University of Pennsylvania and principal researcher at fQ. If that's true, it's magical. ”

The reasoning behind this idea comes from previous discoveries by physicists, a 2006 paper by Masayo Kasa of the University of Illinois at Urbana-Champaign and Masashi Takayanagi of Kyoto University, showing that there is a correlation between the geometry and entanglement of space-time. Building on this work, in 2013, physicist Juan Maldasina of the Institute for Advanced Study in Princeton and physicist Leonard Suskander of Stanford University discovered that if two black holes become entangled, they create wormholes, a shortcut in space-time predicted by general relativity. This discovery (based on the name of the scientist who proposed wormholes and entanglement, which physicists have nicknamed "ER=EPR") and other related work surprisingly show that entanglement, which was previously thought to involve no physical connections, can actually produce spatiotemporal structures. 【1】”

Sure enough, Professor Wu began to talk eloquently.

I had the feeling of sitting in a college classroom.

"Cheng Yin, the knowledge of quantum entanglement is very deep, what do you want to know?" Professor Wu stopped a lot of textbook rhetoric.

"I always felt like I felt a kind of strength that always seemed to guide me in my most difficult times." I really don't know how to ask this question better.

My headache always gives me the direction to move forward when I am most critical, and the game of Go is like a guiding light, which always seems to solve the confusion in my heart. But...

I don't know if this counts as a form of quantum entanglement.

"Cheng Yin, many times our inner voice is more important than many theories." Professor Wu's thoughtful answer did not seem to be answering my question, but more like answering the doubts in his mind.

"Look!! The Shu army camp has arrived!! Cui Li shouted.
