The Giant Tree must leave this dangerous star field.

However, when it wanted to drive the planet it was riding on to leave this star field, it found that the star field where it was located had unknowingly been transformed into a small universe.

In this small universe, in addition to another yellow dwarf, there is only a massive and incomparably magnificent super black hole.

This startled the giant tree.

Because for so many years, when it lived in this star field, it did not find any anomalies.

Before I knew it, I was transformed into what I am today.

A civilization with this kind of ability is completely beyond the imagination of the giant tree.

You must know that the super civilization that can transform the small universe is the top existence in the entire universe.

Not to mention hiding from himself to transform a star field into a small universe.

At first, the giant tree thought that the reason why this civilization locked itself in this small universe was to prepare to nurture itself and let itself help transform some terrestrial planets.

After all, transforming planets is the racial talent of the Giant Tree Clan, and even for the most top-level carbon-based civilizations, it would take thousands of years to transform a terrestrial planet into a habitable planet.

But for the Giant Tree Clan, it only takes a few decades.

Therefore, those carbon-based super civilizations in the universe are all proud to have a giant tree.

The giant tree thought that it had become a giant pet raised by a super civilization.

Yet hundreds of thousands of years have passed, and no one has found themselves.

The giant tree has also tried to leave this small universe, but it only has the power of the strings, and it is still a long way from the power of the membrane, not to mention the power that creates bubbles on the supermembrane.

Therefore, there is basically no possibility for the giant tree to leave this small universe.

Unless it's willing to give up the power it has accumulated over hundreds of millions of years, turn itself back into a small sapling, and then burrow out of that little wormhole.

The giant tree will not do anything until the last moment.

Just as the giant tree was trying to find a way to leave the small universe, he didn't expect that a human civilization individual who had just mastered the power of the point broke into the planet where the giant tree was located.

The giant tree was overjoyed for a moment, although the civilization that had mastered the power of the point was a whole level behind itself, but this human civilization had a terrifying potential for technological explosion.

In the universe, it is not uncommon for civilizations to have technological explosions, but this generally occurs in the process of interaction and integration between two civilizations.

Like human civilization, in the long history of independent evolution, there have been several technological explosions, but it is extremely rare.

This civilization is qualified to be its own partner.

Because of this, after the female human civilization entered Planet Five, the giant tree imprisoned her, hoping to find a breakthrough from her.

……

"Brother-in-law...... Brother-in-law ......"

Pang Xuelin opened his eyes in a daze, and saw a delicate face, looking at him with some concern.

"Ink ...... Murphy...... This, where is this? ”

Pang Xuelin looked around, only to find that where they were was actually in a huge tree hole, which was fluorescent and full of all kinds of strange flowers and plants.

The two shuttles were tangled in vines.

Murphy said: "This is a confined space in the ground where the tree elder is located, and it is also a cage where we are imprisoned, I didn't expect you to be caught as well." ”

"Tree Old?"

Pang Xuelin was slightly stunned, and then saw a vine next to him, suddenly rising, quickly curling up and weaving into the image of a human old man on crutches.

"Hello, young man."

Pang Xuelin was slightly stunned, and said suspiciously: "You are the giant tree that appeared in my dream?" ”

Shu Lao nodded with a smile and said, "You can call me Shu Lao." ”

Pang Xuelin pondered for a moment, quickly sorted out the cause and effect, and said: "Elder Shu, it is understandable that you want to cooperate with human beings through us, but you should know that human civilization is currently in danger and tired, if we have a way to get you out of this small universe, we will not risk passing through the wormhole and coming to this small world." ”

Elder Shu laughed and said, "Who said that I was going to cooperate with your human civilization, I wanted to cooperate with you. ”

"We?"

Pang Xuelin pointed at himself and Murphy with some surprise.

Shu Lao smiled: "Yes, a man and a woman, on this planet, a huge race can be bred in a thousand years, and then use the human knowledge system you brought and the knowledge system I have mastered, which is enough to give birth to a powerful human civilization in this world." When the time comes, they will naturally have a way to help me get out of trouble. ”

Pang Xuelin's brows couldn't help frowning, he looked at the seemingly kind old man in front of him, and said, "So, are you willing to let us go?" ”

Elder Shu nodded and said, "Young man, I still have to thank you for coming, if only this little girl, or if the human civilization has sent a powerful fleet to come, I can't do anything about you." Now it's just the two of you, and that's just right for me. ”

Pang Xuelin frowned and looked at Murphy, and it happened that Murphy's eyes were also looking at him.

The two looked at each other, and a hint of blush appeared on Murphy's fair face.

Elder Shu said: "This world is heaven for you, you don't have to worry about hunger......

As soon as the old man waved his hand, a branch next to it instantly swelled into a fruit tree, full of red fruits.

Shu Lao picked a fruit and handed it to Pang Xuelin, and said with a smile: "Taste the taste." ”

Pang Xuelin frowned, took the fruit, and took a bite, sweet and sour, with a long aftertaste, this is almost the best fruit Pang Xuelin has ever eaten in his life.

Then, the tree elder waved again.

The fruit trees disappeared, and in their place a field of golden rice grew from the ground, and the heavy ears of rice drooped low.

The old tree picked up an ear of rice, and instantly turned into crystal white rice, and the old tree held the rice in his hand, and in a moment, the rice turned into a fragrant rice ball.

"Taste it!"

Pang Xuelin took the rice ball, took a light bite, closed his eyes, and savored it for a long time.

After so many years in this world, he has almost forgotten the taste of white rice.

Shu Lao smiled slightly and said, "If you want to eat meat, I have it too." ”

He waved his hand again, and in an instant, a creature resembling a bull appeared in the cave.

It was when he was on the ground that the cow that was killed by Pang Xuelin with a laser gun.

Shu Lao used his tricks again, and soon cooked two plates of fragrant grilled steaks.

Then, he made two glasses of his special fruit wine for Pang Xuelin and Murphy, put them on the wooden table and wooden bench that had just taken shape, and said with a smile: "I heard that on your planet, steak should be paired with wine to be delicious, you haven't seen you for a long time, eat a good meal first, I won't bother you." ”

As he spoke, the tree elder smiled slightly, and the vine silently retracted it.

Pang Xuelin turned his gaze to Murphy at this time, and said with a smile: "Murphy, have you been like this in the past few months?" ”

Murphy nodded and said with a wry smile: "Yes, although I am imprisoned, I have to say that the living conditions here are indeed beyond imagination." ”

Compared to the shuttle plane, which can only eat a variety of special space food, the delicacy of this natural food has not been enjoyed by them for a long time.

Pang Xuelin said: "Okay, if it comes, it will be safe, and we will not live up to the good intentions of the old tree." ”

Murphy opened his mouth and was about to speak, when he saw Pang Xuelin winking at her, he smiled and said, "Okay, then let's eat first." ”

A steak feast, the two of them are extremely comfortable.

After the meal, Pang Xuelin, led by Murphy, began to visit this tree hole.

The tree hole is about fifty acres in circumference, in addition to a variety of exotic flowers and plants, there are two pools not far away, according to Murphy, one pool is a drinking water source, filtered by the old tree, belongs to the very high quality mineral water.

The other is a source of water for washing.

You can also take a bath in it, and the water temperature can be adjusted at any time according to the requirements.

As for the sleeping place, it is still in the shuttle.

Shu Lao specially vacated the hatch of the shuttle plane to facilitate the entry and exit of the two people.

Inside the shuttle, there is also a large bed with a goose down duvet and mattress specially made for two people.

Seeing this shuttle that had been arranged like a new house, Pang Xuelin looked at Murphy a little, the two looked at each other, Murphy's face was slightly hot, and he couldn't help but think of that intoxicating night many years ago.

Pang Xuelin didn't think so much, he sat down on the edge of the bed, frowning lightly.

Murphy said, "Brother-in-law, we ...... What do we do next? ”

Pang Xuelin said: "Let's take one step at a time, by the way, Elder Shu, you come out." ”

Pang Xuelin's voice fell, and a vine outside the shuttle suddenly entered the shuttle and turned into an old tree again.

"Mr. Pang, is there anything you need my help with?"

Tree Elder smiled.

Pang Xuelin said: "Didn't you say that you want to find a way to enter and exit the small universe?" Can you tell us about any research you have on this? ”

Shu Lao smiled slightly and said: "Mr. Pang, today is your wedding night, other things should wait until tomorrow, after all, compared to solving the problem, the most important thing now is how to expand the population, if you are a little embarrassed, then I can help you......"

As he spoke, Shu Lao waved his hand, and a pink mist suddenly appeared between Pang Xuelin and Murphy.

Then, the tree man left the shuttle with a swoop, and the hatch closed again.

Before Pang Xuelin saw a flash of fire in his eyes, he vaguely heard the voice of the old tree: "Mr. Pang, Ms. Murphy, I wish you a hundred years of happiness and an early birth to a noble son." ”

Pang Xuelin turned around, and a fiery body threw himself into his arms.

"Brother-in-law......"

……

The next day, when Pang Xuelin appeared in front of Shu Lao with Murphy, who was still a little shy, Shu Lao smiled and said, "Mr. Pang, how was your rest last night?" ”

Pang Xuelin rolled his eyes and said, "Elder Shu, now you can talk about what kind of help you need us to give you technically, right?" ”

Shu Lao smiled faintly, shook his hand, and a white piece of paper made of wood fibers appeared out of thin air, on which was a large paragraph of mathematical text written in the language of the earth: "Mr. Pang, I heard Ms. Murphy say that you have a very deep research in the field of mathematics, can you help me solve this problem?" ”

Pang Xuelin took the blank paper and looked at it.

"Huh?"

Pang Xuelin couldn't help but let out a soft sigh.

There is only one problem on paper, which is very complex in mathematical language, to the effect that there is a small smooth "space", which is described by a set of equations such that this space has a uniform dimension. Then we take the basic "topology" information and break it down into smaller geometric parts. The rational stuff within the geometric part is called the "Hodge cycle". Each smaller geometric part is a combination of geometric parts called algebraic loops. Basically we have a "pile". Let's take a closer look at it and see that it is made up of many "chopped wood". "Chopped wood" with "twigs" in it

Now the tree elder hopes that Pang Xuelin can prove that for piles of chopped wood, the branches are actually a combination of geometric parts called atoms.

This expression may seem difficult to understand, but in layman's terms, it is that for the geometry of any shape, no matter how complex it is, it can be put together with a bunch of simple geometric figures.

On Earth, this conjecture is known as the Hodge conjecture.

Together with the P and NP problems, the existence and smoothness of the N-S equations, the BSD conjecture, the Yang-Mills gauge field existence and mass interval hypothesis, the Riemann conjecture and the Poincaré conjecture, it is known as the seven major problems of the millennium.

In the real world, Pang Xuelin remembered that Perelman was in retreat at Jiang University to solve the problem.

He didn't expect that Elder Shu would put this question in front of him today.

However, Pang Xuelin quickly reacted, and the Hodge conjecture, together with Fermat's great theorem and Riemann's conjecture, is a carrier and tool for the geometric topology of the structure of M theory that integrates general relativity and quantum mechanics.

In the 11-dimensional space of M theory, there is the extension of the four-dimensional space and the contraction of the seven-dimensional space.

The topological properties of geometry are closely related to particles. For example, this particle geometry has several holes that determine the number of particle generations, and the geometry of these convoluted dimensions determines what kind of vibration mode the string or membrane can have, and thus the coupling constants of various interactions such as mass, spin, and charge of various particles.

It turns out that not only the internal variables such as spin and isospin and the internal space are derived from the geometry of these multidimensional spaces, but also the properties of the particles, such as the charge mass, are all generated from here, and not only that, but even our life itself grows from the construction of similar geometries through three-dimensional space and one-dimensional time.

Therefore, as long as the Hodge conjecture is solved, then human cognition of multidimensional space and new physical theories based on M theory will have a leap forward.

Especially for a creature like Shu Lao, who has evolved for an unknown number of years, this kind of mathematical law involving the essence of physics is exactly what he is missing.
