In order to rescue Lin Xueyi from the black hole, the ancient Buddha proposed the following technical schemes: first, with the help of Einstein's theory of relativity, time is compressed to expand the space of the black hole. The second is to use the "cosmic strings" created by string theory to pull her out.

According to the predictions of scientists, the string theory is likely to become the ultimate theory, so the ancient Buddha of the burning lamp created this "cosmic string". At present, quantum mechanics that describes the microscopic world is fundamentally in conflict with general relativity, which describes macroscopic gravity, and the smooth space-time of general relativity contradicts the violent quantum fluctuations of space-time under the microscopic world, which means that both cannot be correct, and they cannot describe the world completely. In addition to gravity, quantum mechanics naturally and successfully describes three other fundamental forces: electromagnetic, strong and weak. String theory may also be one of the solutions to quantum gravity. Superstring theory also contains fermions, one of the elementary particles that make up matter. It is still unclear whether string theory can successfully explain the universe based on all the forces and matter currently known to the physical world, and whether it can be applied to extreme cases such as "black holes" and "the Big Bang" that require the use of both quantum mechanics and general relativity.

In order to bring happiness to Lin Xueyi's stream of consciousness, thus creating a time contraction effect and expanding the space, the ancient Buddha wanted Lin Xueyi to listen to beautiful music. Where is this kind of music? How can such music be produced? What instruments do you use? The ancient Buddha of the lamp rummaged through ancient and modern Chinese and foreign ancient books, and found a way to make the guqin in the first volume of "Warning to the World" "Yu Boya Throwing the Qin Xie Zhiyin".

According to legend, this piano is carved by Fu Xi, see the essence of the five stars, fly down the sycamore, and the phoenix emperor comes to the ceremony. The phoenix is the king of a hundred birds, and it is not eaten by bamboo, it is not inhabited by Wutong, and it is not drunk by Liquan. Fu Xi knows that the sycamore is a good material in the tree, and the essence of creation is worthy of elegant music, which makes people cut it. Its tree is three feet high and three feet high, according to the number of thirty-three days, cut into three sections, divided into three talents: heaven, earth and man. Take a section and knock it, its sound is too clear, and it is too light and abandoned; Take down a section and knock it, its sound is too loud, and it is abandoned because it is too heavy; Take a middle section and knock it, its sound is clear and voiced, and it is both light and heavy. Send it to the long flowing water, soak it for seventy-two days, according to the number of seventy-two waits. Take up the shade, choose a good time and an auspicious day, and use the master craftsman Liu Ziqi to make musical instruments. This is the joy of Yaochi, hence the name Yaoqin. 3 feet 6 inches 1 minute long, 361 degrees on Sunday; Eight inches wide in front, eight knots; The rear width is four inches, and it is pressed at four o'clock; Two inches thick, press two instruments. There are golden boy heads, jade girl waists, fairy backs, dragon pools, phoenix swamps, jade splendors, and gold emblems. That emblem has twelve, according to the twelve; There is also a middle emblem, according to the leap month. First, the five strings are on top, and the outside is pressed by the five elements: metal, wood, water, fire, and earth; Inner according to the five tones: Gong, Shang, Jiao, Zheng, Yu. Yao Shun played the five-stringed piano and sang the poem "South Wind", and the world was under great rule. Later, because King Wen of Zhou was imprisoned in Xianli, he hung his son Boyi and added a string, which was quiet and complaining, which was called Wenxian. After the martial king, the song and dance before the war, add a string, and carry it out fiercely, which is called the martial string. First, there are five strings of Gong, Shang, Jiao, Zheng and Yu, and then two strings are added, which are called Wenwu lyre. There are six taboos in this piano, seven do not play, and eight are absolute. What are the six taboos? One is to avoid the cold, the second is to avoid the heat, the third is to avoid the wind, the fourth is to avoid the heavy rain, the fifth is to be thunderous, and the sixth is to be afraid of heavy snow. What is Seven Don't Play? Those who hear the mourning do not play, do not play music, do not play redundant, do not play if they do not clean their bodies, do not play if they are not neatly dressed, do not play if they do not burn incense, and do not play if they do not meet bosom friends. What are the Eight Uniques? In short, it is strange and elegant, tragic and long. This piano is touched to the fullest perfection, the howling tiger hears but does not roar, and the mourning ape listens but does not cry. It is also the benefit of Yale.

The Ancient Buddha used his supreme mana to make a guqin according to the above method, and invited a fairy to play it. In the natural sound of the guqin, Lin Xueyi enjoyed the most elegant art. With the sound of the piano, Lin Xueyi only felt that time was whistling, and her body gradually increased from the size of Schwarzschild radius, and in an instant, it had become the size of an electron, and further expanded to the size of atoms, molecules, and cells. The fairy rearranged the strings and pondered for a long time, which meant that the mountains were high and stroked the piano. Lin Xueyi praised: "It's beautiful, the meaning of fairy music, in the high mountains!" The fairy didn't answer. After concentrating for a while, the piano was drummed again, which meant flowing water. Lin Xueyi praised again: "It's beautiful, and the ambition is to run water!" After the fairy finished talking about the song "Mountains and Flowing Water", Lin Xueyi's body continued to grow to the size of a fist.

I saw a thin string float in from beyond the black hole. Due to the huge gravitational pull of the black hole, this cosmic string is pulled thinner and thinner by the black hole, and it looks like it is about to break. Lin Xueyi held this string, only to feel a powerful force pulling it out. At this time, she is subjected to the huge gravitational pull of the black hole on her left, and the huge pull of the cosmic strings on her right. These two huge forces acted on her at the same time, as if she was being tortured by "two horses splitting the corpses", which was very uncomfortable.

In the cosmic strings made by the Ancient Buddha of the Burning Lamp, there are no particles, only the strings move in space, and the different particles are just different vibration modes of the strings. All the interactions that occur in nature, all matter and energy, can be explained by the splitting and bonding of strings. Pluck a string on the guitar and you'll hear a note. Pluck another string and you will hear another different tone because different strings vibrate in different patterns. A musician can create a myriad of beautiful music by playing a six-string ensemble of a guitar and vibrating the strings at different frequencies. Just as the different vibration patterns of the strings play different musical sounds, the strings inside the particles also have different vibration patterns, except that the vibration of the strings does not produce any music, but produces individual particles. The properties of different particles are determined by the different vibrational behavior of the strings, the electrons are strings that vibrate one way, the upper quarks are strings that vibrate in another, and so on. According to string theory, each elementary particle exhibits properties that result from the different vibrational modes of the strings within it. Every elementary particle is made up of a string, and all strings are absolutely identical. Different elementary particles are actually playing different "tones" on the same string. The universe is made up of countless such vibrating strings, like a great symphony.

When Lin Xueyi was pulled by both sides and was in a dilemma, the Burning Lamp Ancient Buddha opened another function of the cosmic string - releasing anti-gravity. Under the vibration of a certain mode of the cosmic string, antiparticles can be generated. Antiparticles have opposite gravitational fields. Two antiparticles will gravitationally attract each other like two ordinary particles, but one antiparticle will repel one ordinary particle. Under the action of antigravitons, part of the gravitational pull of the black hole is canceled out. In the end, Lin Xueyi's body was not torn, and she was rescued from the black hole.

Standing in front of Lin Xueyi, there were three fairies who lit the lamp, Hu Kehao, and played music. After Lin Xueyi's physical body escaped from the black hole, the Burning Lamp Ancient Buddha released her stream of consciousness through Hu Kehao's Yintang acupoint. After the combination of physical body and stream of consciousness, Lin Xueyi became a normal person.

Lin Xueyi didn't see Dong Yucheng beside her, she was extremely dissatisfied in her heart, this person usually has a smooth tone, and he ran away without a trace at the critical moment. What she didn't know was that Dong Yucheng had looked for her on the side of the mountain col, but he didn't find anything, and he didn't believe Professor Yang's theory of black hole swallowing people, so he didn't stick to it, so he waved his sleeves and left, not taking a cloud with him.

"Xue Yi, it was the Ancient Buddha who saved you!" Hu Kehao said.

Facing this kind old man, a warm current swept through Lin Xueyi's body. Without thanking him, Hu Kehao and Lin Xueyi both folded their hands and saluted, and read: "Nan Wu Burning Lamp Ancient Buddha!" Nan no Medicine Master Liuliguang King Buddha! There is no past, future, and present Buddha in the south! There is no Shakyamuni Buddha in the south! There is no Amitabha Buddha in the south! …………”

In the Buddha name they recited devoutly, the ancient Buddha and the fairy turned into a cloud of light and left.
