Lu Sheng had already taken his things and returned to the living room, and when he walked to the door, he heard the conversation between Zhang Lan and King Zhao, especially after hearing King Zhao's sad words, he felt empathy and was a little distracted, so he stopped outside the door, and when he heard Zhang Lan say that it was possible to return to the time and place when they came, his shock was greater than that of either of the two of them.

Lu Sheng, who was still a toddler at the time, was forcibly stuffed by his grandfather to King Zhao's side despite the opposition of his family and followed him to resist the Yuan. At first, he was very resistant, after all, there was a world of difference between the brocade clothes and food at home and the life and death crisis of sleeping in the open by King Zhao's side. But with the passage of time, he gradually integrated into the team of King Zhao, and felt more deeply the brutality of the Tatars and the evil deeds of his compatriots, and his resistance disappeared, although he was young, but because of his precocious mind and outstanding military talent, he made many miraculous feats in the ranks of King Zhao, and later was relied on by King Zhao as his right-hand man, and in fact, the surprise attack on Mengyuan's grain road was planned by him, and it should have been a successful operation, but he did not want to be targeted by a guerrilla cavalry of Mengyuan who fought the autumn wind, Even so, they accomplished the purpose of the operation.

And came to this world unexpectedly, he never gave up returning to the Song Dynasty to continue the cause of resisting the Yuan, after falling into the goblin clan, he also actively cooperated with the goblin sacrifice, using the basalt carapace as a lever to win the support of the goblin clan, and when the artifact of the red crystal gun arrived, he was so excited that he couldn't sleep for two days, because he knew what it meant after this artifact was applied to the battlefield of the Song and Yuan dynasties.

In the matter of going home, he is even more enthusiastic and active than King Zhao, because compared with King Zhao, who is almost alone, there is his grandfather behind him, his parents and his family, compared to the righteousness of the country and the nation, he has a more real motivation to push him forward, because he has seen more of Meng Yuan's tyranny, he knows better the consequences of the loss of his homeland, so he has been trying to find ways to go home for more than ten years, and he has found nothing for a long time, and he has grown from a teenager to a young man. Recently, however, he finally found a clue.

But just when hope came, Zhang Lan appeared and told him that his relatives and family had been transformed into floating corpses on the sea behind the cliff mountain seven hundred years ago, and the heroic soul was gone. As a result, his shock and grief can be imagined, until now his chest is still very painful, and at this time, after hearing Zhang Lan's speculation, the turmoil in his heart is as great as the grief deposited in his heart.

When he saw Zhao Wang and Zhang Lan looking at him, he picked up the iron box that fell to the ground, picked it up and walked into the living room. Then put it on the coffee table in the living room, and then he sat down at the head of King Zhao, facing Zhang Lan's surprised King Zhao's gentle and comforting gaze, he forced himself to calm down, nodded to the two of them, and signaled that he was fine.

"Brother Zhang, what did you mean by what you just said, now Lu Sheng is also here, can you elaborate on it." King Zhao stared at Zhang Lan eagerly and asked, in the original world, many things were regarded as nonsense, but there were no scruples here, just because there were too many things to see and experience here, anything could happen.

"A girl who came to this world with me, we are more than a year apart in the original world, and I am in the historical process that is more than 700 years different from you, and here we are only more than ten years apart." Speaking of this, Zhang Lan paused and looked at King Zhao, who listened carefully and motioned for him to continue.

"So I think our original world must be connected here in a higher dimension, time and space are folded into a single point, and we will be in a timeline and space plane when we enter this world from any time and space, so our span will be so small. In the original world, such cases occasionally occurred, such as airplanes that flew for decades, ships that spanned a hundred years, and people from the future and the past, who must have traveled through the four-dimensional or even five-dimensional space as a transit station, although these cases rarely occur, but they are not nothing. And the time and space in which we live is even rarer for these cases. Because we not only crossed the high latitudes, but also penetrated them, penetrating into the three dimensions of the high-latitude package. The more Zhang Lan spoke, the more excited she became, and she looked like she was dancing, and King Zhao was already frowning and couldn't understand the terms he said.

"As far as I've seen along the way, the three-dimensional space in the high-latitude package we traverse is more stable and sustainable than those that happened by chance, because it is still merging with other spatial and temporal matter. As long as it is a stable space, there will definitely be some entrances and exits, and the entrances we enter must still be somewhere on the high-latitude diaphragm that envelops this space, because of the difference in dimensional nature, they must move everywhere in time and space in this three-dimensional world, but they must not disappear, because this world is stable now. The more Zhang Lan spoke, the more excited he became, he didn't know why he knew this, but when he thought of the other things at the beginning, he flowed out of his mouth, he felt that he was really a genius and could even say these surreal things.

"Is it because I have watched the science fiction world for more than ten years" Zhang Lan took a sip of tea, rubbed her chin habitually, and was complacent, but she put aside the objects Zhao Wang and Lu Sheng, who originally wanted to be comforted, unheard of, and the unknown words made the two of them dumbfounded and dumbfounded.

After a long while, King Zhao spoke: "Hehe... Although I don't understand what Brother Zhang is talking about, but looking at the way you say it, Brother Zhang must be very confident in his reasoning, no matter what the theory is, as long as the hope of us going back still exists, it is enough" King Zhao saw that Zhang Lan was only caring about himself over there, and he had to speak out to break the silence.

"Ahem... I'm sorry, but I mean simply, we still have hope of going back, but it's extremely slim, and it's almost impossible for the three of us to succeed. Pulled out of her fantasy by King Zhao, Zhang Lan was shocked to realize that she had deserted again, and hurriedly threw out a conclusion to hide her embarrassment.

"Hehe... Brother Zhang is really a person seven hundred years later, and the knowledge he has come into contact with is really intimidating to the old man, but I have heard the allusion of "one day in the mountains, a thousand years in the world", I don't know if it is the same thing as Brother Zhang" King Zhao saw Zhang Lan's embarrassment and said casually.

"Yes, yes... As long as we find the right way, we can not only go back in space, but also in time" Hearing the allusion told by King Zhao, Zhang Lan suddenly realized that China has long had a story of crossing.

"In that case, let's take a look at this clue to go home" King Zhao looked at Zhang Lan's sworn appearance, nodded with satisfaction, and then walked to the iron box placed on the coffee table, and took out a columnar red crystal from his body as he walked, and inserted it into an empty slot of the iron box.

At first, Zhang Lan thought that Hongjing was the key, and King Zhao was using Hongjing to unlock the lock. And when King Zhao stuffed all the red crystals into the empty slot, Zhang Lan's eyes were full of incredulity, because the red crystal melted like an ice cube, and then the melted liquid emitted red light and flowed along the inexplicable carvings on the box, until the entire iron box was wrapped, and then there was a crisp sound of "ding", and the iron box was automatically rolled out, and then a three-dimensional line drawing with blurred lines was projected into the air.

"I rub ... High-tech! Zhang Lan couldn't help but whisper.
