"I'll tell you the truth, I've encountered this thing once before. Tong Mu said thoughtfully.

"Huh?" The wine cup was very puzzled, but did not ask, and looked at the young man in disbelief, stunned and speechless.

Tong Mu's eyes regained clarity, pointed to the small sapling not far away, and said quietly: "In this sea of souls, above the origin of my arhat herbs. ”

"Hmm, this thing is arhat grass?" The wine cup followed Tong Mu's fingers, and looked at the poorly cultivated small tree not far away in confusion, very puzzled, isn't the arhat grass a weed? How can there be such a thick weed......

With infinite curiosity, and without waiting for Kirimu to speak, the old man flew straight over, and circled around the so-called 'arhat grass', and from time to time there were strange sounds from his mouth, as if he was very interested in this thing.

"It's kind of interesting~!"

After a long time, the old man's mouth popped out of the ridiculous four words, and Tong Mu smiled bitterly when he heard it.

In the end, the old man fell on the black spot on the small tree, and Tong Mu knew very well how he showed the black spot, how to force the black spot out, and how to put it into the small gray ball and hurt people with the help of Baili Bei's desolate mask. I talked to the old man in detail, and when I heard the old face of the wine cup, it was white and red, and he kept giving Tongmu a thumbs up.

"The guys with thick eyebrows and big eyes are really bad embryos~!"

In the end, the wine cup looked strange, looked at Tong Mu with a little more jealousy, and a little admiration, and then fell into deep thought, it seems that the questions encountered by Tong Mu also plagued the old man in front of him.

Why is the black dot on Gaia so similar to the black dot on the origin of Kirimu's magic?

If you use Tong Mu's method, with the power of picking stars to promote the elimination of toxins, with Tong Mu's cultivation, it is already great to be able to complete this feat within a hundred years, but how can the two of them be in this mysterious space for so long.

The two were relatively speechless, and they were in a dilemma for a while, but fortunately, the length of the giant tree at this time suddenly slowed down, and it seemed that it was about to stop growing, otherwise Tong Mu could only choose to rescue Yun Shayue first.

But once this happens, he and the remaining ghost generals will be unable to deal with each other, which means that he must choose between his lover and his brother.

He looked at the object in front of him quietly, and there seemed to be no other anomalies or potential dangers.

With a long sigh of relief, he began to carefully observe the strange Xiaoquan in front of him, and he was momentarily distracted.

Compared to him, the old man was the first to regain his composure, he stroked his white beard, staring at the black spot on the origin of the Tongmu Soul Sea, his face distorted, as if he was caught in some kind of fierce ideological struggle.

He is the last wandering soul left by the great civilization, although he has long lost his body, and his mental strength is very poor, but after all, he has inherited almost all the memories of the Chinese tombstone, whether it is insight or knowledge reserves, it is far from being comparable to this barren Wutong Da 6, after careful exploration and comparison, although he still does not know what is in front of him

What, but he still vaguely found a way to deal with this thing.

Tong Mu looked at the old man blankly, through getting along with the wine cup day and night, Tong Mu admired this old man very much, and the other party mastered the cultivation method that subverted the entire cultivation system, which was called science.

Through his understanding of science, he now has an extremely powerful system, which can even make up for the shortcomings of the cultivation system to a large extent, and if it can be used, it will definitely have an unexpected effect.

The wine cup was a little hairy by Tong Mu, and he knew too much about that look, and it was too familiar.

This is exactly the way those comrades full of regret look at them on the eve of the destruction of Gaia's civilization......

Those people are trying to say......

You are the hope of the whole village......

At that time, he did not have the ability to save the entire civilization, but now, he is fully capable of helping the apprentice in front of him who has been poured his heart and soul into it.

The wine cup smiled knowingly, stretched out his hand to grasp the void, and suddenly a strange transparent crystal plate appeared between the two, and the old man did not speak, but drew directly on the crystal plate.

Tong Mu looked closely, and there were strange runes drawn on it that Tong Mu couldn't understand at all.

"This is called advanced mathematics, the scientific system I told you before, mathematics is the cornerstone of this system, equivalent to the origin of your world. The wine cup patiently explained, but did not stop the movements in his hand.

"Then this origin has a powerful attack power?" asked Kiryu very puzzled.

"No, but it's much more powerful than attack, and it contains the basic mysteries of the natural world, which, in your words, can help you get closer to the rules themselves. The old man said solemnly.

"There is such a magical thing, can you teach me?" asked Kirimu curiously, as he seemed interested.

"Yes, but not now, the math system I use is called calculus, do you remember the old man who played the violin when we first met?"

"Remember, I like his style. Tong Mu said.

"He's one of the greatest scientists of our civilization, and he's very talented, but do you know how long it took him to learn calculus?" said the old man seriously.

"How long, a month?" asked Kirimu puzzled.

"Five years ......," the old man said calmly.

"It's okay......" Kirimaki said innocently.

But that's based on his deep understanding of basic mathematics, and it takes at least 10 years to learn from scratch. The old man's tone was still calm.

"Well, it's okay, our Wutong Big 6 cultivators can live for at least a few dozen decades, and I have patience. Tong Mu scratched his head and said.

"I don't doubt that, so I'll teach you when this crisis is over. The old man said kindly.

With the conversation between the two, many crystal plates were already filled with dense symbols, and Tong Mu was extremely surprised to see it.

With the last

With a single stroke, the old man's frowning brows finally relaxed.

"That's right, this thing is fluid. The old man said with great certainty.

"Fluid?"

"Yes, fluids, and fluids at room temperature. ”

Jiu Mu looked at Tong Mu firmly, and explained: "Fluid is a form of matter, to put it simply, it is similar to the gold, wood, water, fire and earth that your world understands, it is a very basic thing in physics, and it is extremely difficult to study. ”

"Our civilization has done a lot of research in this area in the early days, and in the end, it is now that fluid is something more basic than many physical phenomena, and it is likely to touch the essence of the universe. In this state of matter, matter is completely devoid of viscosity, and there is almost no energy loss in the process of movement, that is, if there is no external intervention, it can move like this endlessly. ”

The wine cup explained very hard, but Kirimaki still didn't understand, just shook his head.

"About physics, I will teach you a little bit, you just need to know now, this thing in front of you is called fluid, and this miniature fountain in front of you is doing some kind of flow phenomenon operation, there is a little bit I didn't figure out before, through mathematical calculations, I can figure it out now. The wine cup looked at Tong Mu solemnly and continued:

"In the physical system of my world, fluids still only exist at low temperatures, and this thing ......"

The old man's eyes were deep, and he seemed to have a thousand words, but he didn't know where to start.

"You mean...... Shouldn't natural fluids exist?" Kirimu was exposed to the wine cup a few days ago, and seemed to understand some of the terminology of basic physics, so he participated in this thinking.

"It's right and it's not right...... I used to think that our civilization physics had not reached that level, so we had not been exposed to fluids at room temperature, but now it seems that this is not the case. ”

Speaking of this, the old man's eyes burst with essence, and he said loudly: "Maybe there is really a fluid at room temperature in this world, but this one in front of me is not, the reason why this thing is here is because it does not belong to this universe at all!"

The sound of the wine cup was word-by-word, and Tongmu was shocked when he heard it.

What does it mean not to belong to this universe?

You mean this thing appeared out of thin air, right?

Or is there other worlds between heaven and earth besides the world in front of you?

A world different from the upper and lower realms?

Tong Mu shook his head in pain, and suddenly felt that the world was turning.

Who am I?

Where am I?

Why do I exist?

The space of consciousness I am in now does not belong to the Sycamore Big 6?

When did the world begin, and when did it end?

If there is more than one universe, what is its purpose?

Finally, his eyes went black and he fainted.
