The old man, who was like a homeless man in another world, exuded wisdom and friendliness all over his body, and if it weren't for his patched shoes and robes, Cheng Yun would definitely not have associated him with the homeless man.

When Kun Zhen introduced himself again in more detailed words, Cheng Yun began to look at him again.

He looked very old, his hair was completely white, his pupils were slightly cloudy from age, and his face was kind and not wrinkled. He was wearing only a very simple cloth robe, with four or five patches just by touching it head-on, and he was holding a staff about 1.8 meters in his hand, and the baby's arm was thick, but it was very eye-catching, because the top of the staff was inlaid with a crystal ball the size of an apple.

Other than that, it doesn't seem like there's anything special.

But Cheng Yun felt that he was full of special points, especially when he walked out of the luminous body, let himself understand his unknown language, and told himself: He was from another world and was a spell caster.

"My name is Cheng Yun. Cheng Yun said quickly, "Master Spellcaster, may I ask what you are doing here?"

"Huh?" Kun Zhen didn't answer him, but squinted his eyes slightly and looked at him, and sighed helplessly for a long time: "You are really a lucky person!"

"Huh?"

"I sensed the appearance of a space-time node, very close to my world, so I came and took a look. Kun Zhen said with a smile, then stretched out his hand and spread it out, and there was a piece of mini soap ordered by the hotel on the palm of his hand, and there were four square characters written on the soap -

Anju Guesthouse.

"Did this token flow from here?" Kun Zhen asked.

"No!" Cheng Yun decisively denied.

"Oh. ”

"You said you just came to have a look?"

"Yes. ”

"Then please go back. "Cheng Yun's mind is very messy.

"I think you need my help. Kun Zhen was unimpressed by his attitude and smiled.

"You're wrong, I don't need to. ”

"You have a lot of questions that I need to answer for you. ”

"No thanks. ”

"......" Kun Zhen was stunned, then shook his head helplessly, and then turned to point to the luminous object and said, "Don't you want to know what that is, don't you want to know what this place is?"

"Thanks, you better go back. ”

"It's already there, I'm just the first to come, but it won't be the last. You should feel lucky, or at least lucky, that the first thing you met was me, not anyone else. "It's a staging post, and there will be a steady stream of people coming here, some of whom may be weak compared to you, some of whom may have the power to destroy your world, but what you don't know for sure is if each of them has a good temper." ”

"Uh......" Cheng Yun was a little shocked, and then he said, "But I'm not a superhero, and I can't take responsibility for such a big thing." If it doesn't work, I'll close the door, I don't want this warehouse!"

Kun Zhen shook his head again and stared at him calmly: "Some people will have to stay here for a while, maybe some people can go without eating or drinking, but there are also people who can't bear hunger and thirst. If you close the door, someone will starve to death here. ”

"I don't know them and I'm not the Virgin. ”

"Yes, I understand what you mean, I'm not a Virgin either, but I've decided to help you here. Kun Zhen said calmly, smiling at him, "If you can easily decide the life and death of a person who has nothing to do with you, I think most people should let this person live." ”

"But it wasn't easy, and I was taking too much risk. Cheng Yun subconsciously retorted.

"It's not as big as you think, it's just that because you don't know anything right now, you don't know how to control those people. "But it's okay, I can teach you." ”

Without waiting for Cheng Yun to speak, he said again: "Maybe this matter is indeed not as easy as I just said, but you are not without gains. It can bring you a lot of things, more than you can imagine, and even more than I can imagine. ”

"Huh?"

"You're tempted. Kun Zhen said firmly.

"I didn't. Cheng Yun said no, then sat down cross-legged, "Come, old man, let's talk slowly." ”

Kun Zhen smiled, sat down informally, and then began to speak: "This is a space-time node, which can also be called a space-time relay point, which is roughly equivalent to a transit station connecting various universes. It exists in every world, but it does not necessarily awaken, and awakening here means becoming a 'staging station'. The vast majority of space-time nodes are asleep, and there is one in our world, and I have found it and stayed with it for ten years, so I know something about it. ”

"But unfortunately, it has been 'sleeping' in our world. Until it changed position again, I lost it. ”

Cheng Yun listened with a confused face, he was not the protagonist of a certain system who forcibly reduced his IQ, this kind of strange thing even if he used the known knowledge to understand it, it means that he is incapable of understanding.

Fortunately, acceptance and understanding are two different things.

Kunzhen continued: "Almost no one knows how it exists, how it was born, and according to the vastness of the universe, its longevity and its uncertainties, almost no one can find it in the long river of time, and there are almost no people who can keep it awake, and more often it is still asleep until the world is exhausted. And the probability of someone being around when it wakes up is even lower, and I've spent ten years researching it to turn it on, but as you can see, I couldn't make it. ”

"It's a very low probability to become one with it, and you are so lucky to meet it in such a coincidence that the endless universe and the long years have constructed. ”

Cheng Yun couldn't help but tug at the corners of his mouth: "So I'm one with it?"

"Yes, it probably takes an extremely harsh coincidence. ”

"But what's the use of that?"

"I'm here now, and I need your help if I want to leave here, return to the original world, or continue to a destination. Kun Zhen smiled at him politely, "At the same time, when there are other people traveling through time and space in the nearby world, if the distance is too far or their own ability is not enough, they need to borrow the time and space nodes of this world for transit, and then they need your help." ”

"I ...... What if I don't help?" Cheng Yun asked again.

"They won't be able to leave. "Maybe someone will be trapped in the node space until they die, or maybe someone will find some way to enter your world from the node space for the rest of their lives, and then you may be in trouble." ”

"Well, you're intimidating me. Cheng Yun was a little disdainful of this kind of persuasion and intimidation, "And this has nothing to do with you." ”

"I'm telling you the truth. Kun Zhen looked at him calmly, "I've seen other open space-time nodes, but I've only seen one space-time node that fused with a certain creature. Theoretically, you will have a lifespan that is level with the nodes of space-time, and then in contact with the endless world, if you wish, this long time is enough for you to reach a height infinitely close to the gods in the broadest sense, so in fact you will probably live longer than this universe. ”

"It's not just your responsibility, it's your opportunity. Kun Zhen retracted his gaze, "How many times have I tried to touch this opportunity, but I haven't been able to touch it." ”

"......" Cheng Yun fell silent, these words sounded too exaggerated.

He began to make up in his head: if what this old man said was true, would he have hit himself with his ideas? He didn't get the time and space node of 'awakening', so he planned to rob himself? If so, then he ...... Just give him it.

"Then I'll just give this thing to you, do you know how to transfer this thing?"

"......" Kunzhen was speechless.

Cheng Yun finally understood that this thing could not be transferred, which also made him breathe a sigh of relief, at least reducing the possibility of the old master seeking money and killing him.

Then, the old master began to explain to Cheng Yun about the space-time nodes, but most of them were theoretical knowledge, that is, the results of his previous research, and there was no practical support.

It seems that the old man is a very bullish person, and the patched robe should be his weapon, but he said that many things will not be known until he has studied them. If Cheng Yun is willing to cooperate with him in the research, he will share the results of the research with Cheng Yun.

And according to the old man, he came here, but he couldn't leave on his own. Because the space-time node has completed the fusion with Cheng Yun, it is equivalent to having consciousness, which is beyond his expectations, and now he needs the consciousness of Cheng Yun, the space-time node, to learn to operate the space-time node before he can send him back. But he is not in a hurry to leave, the purpose of his coming here is to study and continue the space-time node, to find more wisdom, it is better now, at least the space-time node can take the initiative to cooperate with him.

Cheng Yun thus became the object of the old master's research.

The old mage actually didn't rely on spells to cross over, but relied on a scroll made of strange materials, and now that scroll was floating above Cheng Yun's head, and it was very clearly reflected by the faint blue light. It's just that Cheng Yun hasn't looked up before, so he hasn't found it.

But after arriving in this space, the old master seemed to have temporarily lost the scroll, and he demonstrated it to Cheng Yun on the spot - he floated up and reached out to grab the scroll, but the scroll disappeared abruptly, and then appeared on the other side. However, Cheng Yun was able to hold the scroll as soon as he stretched out his hand.

The old man used a 'rule of the game' to describe this phenomenon, because he didn't understand the principle for the time being.

The two studied for two hours, but they couldn't figure out how Cheng Yun should operate the space-time node, but the old master subverted Cheng Yun's inherent cognition in three or two sentences.

For example, this space actually doesn't exist on the ground at all, just because Cheng Yun is used to stepping on the ground, so this space is fictional according to his cognition. When the old master convinced him of this fact, the 'ground' disappeared with a bang, and he began to fall, and it took a great deal of effort to get back on his feet. And this space can actually be completely free from the constraints of 'space' for him, as long as he wants, he can appear in any place.

Only then did Cheng Yun realize that he was truly integrated with this space. And he gradually realized that this may be an unshakable fact.

After a long time, he was almost finished, so he looked at the time of his mobile phone and said to the old man: "I'm tired for so long, let's go out and talk." ”

The time displayed on the mobile phone is already night, if there is no difference between the time flow rate of this space and the outside world, after a while, Cheng Yan should call him to report the results.

It turns out that there is a difference in the speed of time flow between the two spaces - when he walked out of space, the mobile phone displayed the time at 9:36, and after returning to Earth and connected to the Internet, the mobile phone time was immediately synchronized to 9:39.

It's only a little bit worse than horizontal and vertical.

Stepping out of the door, the old man looked back at the door with squinted eyes, and said, "It seems that the space-time node and this place have completed a very interesting combination." ”

Cheng Yun didn't say anything, but walked downstairs: "Master Master, come down and drink a glass of water." ”

The old man followed him down.

He reached out and rubbed the metal escalator, felt the softness of the carpet with his feet, and then glanced at the rooms on the second floor, thinking, his eyes flashing with a strange light.

Everything seemed to be hidden in his eyes.

As he sat on the small sofa on the first floor, drinking warm water from a paper cup, he still looked at everything he could see.

Outside the street lamps and food stalls, the dark city, the occasional noisy car, the side door of the Internet café, the counter computer and the overhead chandelier, water dispenser......

His wisdom is unimaginable to Cheng Yun.

Soon, he put the paper cup on the transparent coffee table and said, "I can see that you are a material civilization, and it seems that you are still in a relatively early stage. ”

Cheng Yun tugged at the corners of his mouth.

It's still relatively basic? You can take a look at your patched clothes before you talk big!

He asked, "What about your world?"

"Our world!" the old man pursed his lips slightly, looking very stylish, "In your words, we should be called a mystical civilization, a magical civilization, a witchcraft civilization, or an energy civilization, a supernatural civilization, and I don't know how to describe it." ...... in our world"

Jingle Bell ......

A bell interrupted him.

"Sorry, I'll answer the phone first. Cheng Yun decisively took out his mobile phone and connected the call from Cheng Yan.

"The score is checked. Cheng Yan's cold voice came.

"How many points?" Cheng Yun immediately asked.

“699。 ”

"Great! Amazing!" Cheng Yun immediately shouted excitedly, especially one point to break 700, "This score must be no problem at Tsinghua University and Peking University, last year's science champion in the province was only in his early 700s!"

"This year, the questions are more difficult. Cheng Yan said.

"That's no problem, have you thought about it, go to Tsinghua University or Peking University. ”

"Nope. Cheng Yan said coldly, "I'll talk about the circle of friends and space, and hang up first." ”

"Forehead ......"

There was a busy tone on the phone.

Cheng Yun put down his mobile phone, looked at the old man with some embarrassment, and said for a long time: "Let you see the smile, my sister is still young, and she is still on the tail of the rebellious period, so she is not very sensible." ”

The old master smiled gently.

"Where did you just go?" Cheng Yun sneered, "You keep talking." ”

"In our world, there is a person who has mastered wonderful abilities, and they are probably similar to your scientists, medical scientists, philosophers, and so on. The old mage didn't care about being interrupted by him earlier, and continued, his tone as always, "I've found a lot of words in the language of your world, maybe I should use words like mage, wizard, spellcaster, etc., to describe our group of people......"

Speaking of this, Cheng Yun's eyes widened suddenly, staring at him: "You...... You're speaking Chinese now!!"

Even after he made a phone call just now, this old master actually learned Chinese, can it be said that the master of that world does not have to endure the suffering of the fourth or sixth level?

"Yes. The old master nodded, "I just acquired the language of your world. ”

"Where did you get it? It won't be from my brain......" Cheng Yun was suddenly stunned, "Wait, the language of our world? Not the language of our country?"

"Yes, I have received the language of this world from this world. The old man's eyes flashed with a strange light, and he affirmed his question, "Your country's, other countries', modern, ancient, still in use, and lost ......"

"......" Cheng Yun looked shocked, "Master Faye, please teach me your spells!!"
