This was the first time Lin Xuan had seen Samantha's true combat strength, there were fifty-five people on the enemy side, more than half of them were loaded with guns and ammunition, and the guns were in their hands, and the other half were busy searching the tunnels to find the murderer who killed Luo Yuan.

Samantha's first shot was to grab the dagger from the waist of the captor, and almost effortlessly sliced the throats of the ten people in the vicinity. The dagger was forged with excellent craftsmanship, and it was only after killing ten people that it began to roll its blade. Then, Samantha abandoned the knife, picked up the short gun discarded by the deceased, fired the bow left and right, and shot at the same time, killing more than 20 people in a row. The enemy near the exit of the tunnel fled quickly, but Samantha chased after him, and after only a few minutes, she retreated, walked slowly, and walked towards Lin Xuan.

It seems that she has already solved everyone, so she will slow down and focus on thinking. After just experiencing a fierce battle like lightning and fire, she can quickly calm down and concentrate on thinking, this kind of super concentration from "extremely fast" to "extremely slow" is exactly the so-called "thought brake" ability that a super spy must have.

Lin Xuan couldn't help but sigh silently: "Russia is one of the three superpowers in the world, and the name of 'polar bear' is indeed worthy of its name. ”

The real superpower must have an extraordinary background, the staffing of any department is capable to the extreme, and any person who stands up will have a very high military quality, combat effectiveness, and thinking ability, and can take charge of himself at any time, and a person can stand up to the work tasks that a team can complete.

After killing so many people, Samantha didn't have a drop of blood on her clothes, and this extremely neat way of killing made Lin Xuan secretly praise. He has long heard that Russian spies are super capable of individual combat, and he has never had the opportunity to see it with his own eyes, but this time he finally has a chance.

As a result, he also lamented Donna's premature death, because he always believed that Donna's ability was definitely above Samantha's.

"Donna, Donna, are you still alive?" Lin Xuan muttered, his heart full of endless melancholy.

When he thinks of what happened to Tang Na, Lin Xuan can't help but think of the classic long poem "Song of Long Hatred" by the Tang Dynasty poet Bai Juyi, which has the following famous sentences at the end of the long poem - I wish to be a winged bird in heaven, and I am willing to be a branch in the earth; The days are long and sometimes endless, and this hatred lasts forever.

At this moment, his disappearance of Donna can only be described by these four verses.

Long hatred song, long hatred, and his thoughts about Donna are destined to run through this life, unstoppable, no matter in the waking dream, will always be entrenched in the depths of his mind.

Samantha walked up to Luo Yuan, looked up at the stone wall above her head, and reached out to touch the spear that abruptly pierced Luo Yuan's throat, with a surprised expression on her face.

Her lips moved, and Lin Xuan read out what she said, "Where did the spear come from?" How could a spear in the painting become a murderous weapon? Who killed him? Is it Lin Xuan? Is this Lin Xuan, really as Sister Tang Na's military report said, a supernatural and extraordinary master? ”

Lin Xuan sighed doubly, Tang Na actually used the words "divine and extraordinary" to describe him, which is already the supreme praise for a man.

That spear was originally just a stroke in the petroglyphs, and even Lin Xuan didn't know how he got it, but now it turned out to be very clear that it was he who grabbed it unintentionally, grabbed the spear in his hand, and assassinated Luo Yuan in an instant.

He couldn't imagine this kind of ending, and Luo Yuan definitely couldn't think of it.

Now, only Lin Xuan and Samantha were left on the spot, and the sight between the two was transparent, and Lin Xuan could clearly see Samantha, but Samantha didn't seem to find Lin Xuan's existence.

In the interrogation rooms of modern police stations, there are such single-sided see-through glass, which can be seen in the observation room, and the invisible face is in the interrogation room. In this way, experienced observers can rely on this kind of peeping to understand the psychological activities of criminals from the body movements of criminals, and make psychological interpretations of those stubborn and stubborn gangsters, so as to solve the case more easily.

Lin Xuan felt that he was standing behind such a piece of perspective glass, which could be seen in one direction and could not be reversed.

"Where did Lin Xuan go? Where did Lin Xuan go? Lin Xuan, Lin Xuan-"

Lin Xuan couldn't hear Samantha's voice, but he could read Samantha's lips. Next, Samantha screamed and ran out, disappearing in an instant.

"I saw it, but I couldn't reach it, I couldn't even touch it...... What exactly is the zài in front of me? What would it be if it wasn't air? Could it be some unknown substance...... Transparent barrier? Lin Xuan tried to stretch out his hand and continued to touch the stagnant air. When he stretched out his palm vigorously, trying to pierce the invisible barrier with his five fingers, it felt like he was poking at a thick layer of raw cowhide. Manually, the raw cowhide also moves, but it can never penetrate through.

"What is it in front of me that I have zài? How could this be--" Suddenly, he understood, "it's a mirror!" That's really mirrored! ”

Yiqiē can only be explained by "mirror", there is a layer of mirror between him and Samantha, that is, at this moment he is already in the mirror, and Samantha is still outside the mirror, and what separates the two of them is a thin layer of mirror.

In the mirror and abroad, both close at hand and far away, it is equivalent to people in different dimensions, even if they are already face to face, but they can't feel each other's existence.

Then, at this moment, Lin Xuan's situation is different from that of another dimension and another world, because he can see Samantha, but Samantha can't see him, which is obviously different from the theory of different dimensions expounded by physicists.

Since the problem of mirrors was involved, Lin Xuan's mind immediately appeared in the process of making mirrors by ancient people.

In ancient times, humans used the technique of grinding and polishing obsidian, gold, silver, crystal, copper, bronze and other unique materials to make mirrors. The history of the development of mirrors is basically like this, in 3000 BC, Egypt invented the bronze mirror for makeup; In the first century A.D., there began to be large mirrors that could illuminate the whole body of a person; In the Middle Ages, portable mirrors appeared in ivory lockets with combs; From the end of the 12th century to the beginning of the 13th century, glass mirrors with silver or iron plates as the backs appeared; In the 16th century, the cylindrical method was invented to make plate glass, and at the same time, the method of making zuò was invented by attaching tin foil to the glass with mercury; In the 17th century, France invented the pouring method of flat glass, and created a high-quality large glass mirror; At the end of the 18th century, large dressing mirrors were made and used on furniture; In 1835, the German chemist Jvon Leibiger invented the chemical silver plating method, which is still used today.

In the evolution of a series of mirror-based methods, single-sided lenses are only suitable for special occasions due to their unique use.

Lin Xuan is familiar with the optical properties of mirrors, that is, the reflection of light by mirrors obeys the law of reflection, and its reflective ability depends on the angle of incident light, the smoothness of the mirror surface, and the nature of the coated metal film.

He had never found a problem before, physicists only talked about things outside the mirror, but did not explain what the world was like inside the mirror.

As we all know, in the concept of physics, the imaginary line perpendicular to the mirror is called the normal, and the angle between the incoming ray and the normal and the angle between the reflected line and the normal are equal. The object in front of the plane mirror is formed into an upright virtual image behind the mirror, and the distance between the image and the mirror is equal to the distance between the object and the mirror. If you want to see your entire length in the mirror, the mirror must be at least half the length of your own body because the angle of incidence is equal to the angle of reflection.

"What happens when the portrait enters the mirror? Are the people in the mirror and the people outside the mirror just simple image projections? Does the shadow in the mirror have mass and temperature? These were all things that Lin Xuan hadn't bothered to think about before.

What seemed like a ridiculous question was clearly placed in front of him at this moment.

"At least, what I see is a normal flat mirror, and there is no distorted change in the portrait." He smiled bitterly in quick thought, and then sighed on his back.

"In the depths of the Siberian mines, may you hold fast to the example of haughty patience, and that your grief-stricken work and noble aspirations of your minds will not perish in vain.

Hope, the faithful sister of calamity, lurks in the dark underground, and she will summon your courage and joy, and the hour of your hope will soon be light......"

Suddenly, someone was reciting this famous Pushkin poem in Russian near Lin Xuan.

He was startled and immediately looked back, but only to see an empty and deep tunnel, far away and near, there was not half a figure.

"Who is it? Who could it be? He immediately sank into the dantian and was ready to face the danger.

"Love and friendship will come to you through the dark prison doors, just as the song of my freedom will reach your caverns of hard servitude.

Heavy chains will fall, dark prisons will fall, freedom will greet you with joy at the door, brethren will bring you swords......"

"Who is it? Who's there? Who's there? Lin Xuan lifted his breath and shouted.

Since there is a voice, there must be someone, and it is a real Russian-speaking person. Although Lin Xuan's Russian is not fluent enough, he still has no problem communicating with people.

He could hear that the voices of those who recited the poem in Russian were full of emotion, and they were definitely people who had a good mind and a vision of the world, just like the Decembrists of those days.

The background of Pushkin's poem is roughly as follows: Pushkin was close to the Decembrists, and although he did not participate in their secret organizations, he was completely politically and ideologically consistent with them. At the time of the uprising of 1825, Pushkin was being imprisoned in a penal colony. After the failure of the uprising, five leaders were executed, and more than a hundred were exiled to Siberia for hard labor. In the course of the interrogation, Pushkin's political poems were searched from almost every insurrectionist's home, and in fact he was also an absent person on trial. When the poet returned from exile, he was very concerned about the fate of these prisoners. At the beginning of 1827, the Decembrists? When Muravyov's wife went to Siberia to visit her husband, Pushkin asked her to bring the poem, which was eventually published for the first time in the London magazine Polaris in 1856.
