In Yunying's boudoir, Ye Xiao had already woken up. He slowly opened his eyes and found himself lying on a warm white jade bed, looking at the layout around the room, it should be a woman's room. The decoration of the room is not luxurious, and the white jade bed is surrounded by a white gauze tent, which is clean and dusty. By the window is a wooden dresser, which is neatly filled with all kinds of cosmetics, but it has been dusty for a long time. On top of the dresser hangs a small lady's sword as a decoration.

However, what Ye Xiao cared about the most was that the whole room was filled with a faint fragrance, and he seemed to have smelled it somewhere. He stood up, came out of the boudoir door, and entered a study. The desk was filled with various map materials, and Ye Xiao was more interested in a painting on the desk than these. In the painting, there is a couple, the male is graceful and graceful, the female figure is graceful, and the bird is leaning on the man's arms like a human. Ye Xiao even saw Yun Ying's shadow from these two people.

"That's my parents. Yun Ying didn't know when she stood by Ye Xiao's side.

Ye Xiao smiled awkwardly, it is not a good habit to move other people's things casually. "It's no wonder that Yun Lingsheng's flower and moon appearance turned out to be a perfect inheritance of Ling Zun and Ling Tang's demeanor. ”

"Both my parents died at the hands of Chu Tianyi. Yun Ying's face was flat, but there was deep grief hidden in the corners of her eyes. "If you hadn't come to his rescue, I'm afraid I would have died at his hands. ”

The second city lord of White Tiger City turned out to be the murderer of his parents, no wonder Yun Ying would single-handedly create the Desolate Sky Army. Ye Xiao didn't know how to answer at the moment, but he saw Yun Ying's red lips lightly, "Thank you." ”

"Commander Yun doesn't have to see outside, since you and I are allies, how can I see death and not save me. Ye Xiaofeng said lightly.

"What you said is light, I will remember the kindness this time. How is your body? That's a killing blow from Chu Tianyi, don't leave any hidden dangers. Yun Ying cared.

"It's out of the way, it's just some trauma, and it's almost fine after taking the pill. "Ye Xiao has already checked his body, he should have been fed some pills when he was unconscious, and he is no longer in a big problem at the moment.

Yun Ying showed a rare smile, like a plum blossom in the cold winter, and fireworks bloomed in the middle of the night, surprising the only guest here. "Then I'll go out for a walk with you, you haven't fully traveled to Black Sand Castle yet. ”

Walking side by side, walking in the courtyard pavilion, the castle was actually more magnificent than it seemed.

"You built this castle?" Ye Xiao couldn't help asking.

Yun Ying's eyes widened proudly, "That's right, I used the phantom city sand to build it according to the remaining murals and picture scrolls of the Ancient Kingdom of the Wasteland, and the design is okay." ”

"I just didn't expect you to have the talent of an architect. Ye Xiao looked around, and had to sincerely admire Yun Ying, even on the earth, this woman can become an excellent architectural designer.

While the two were talking, they walked to a quiet courtyard, Ye Xiao obviously felt that it was much quieter than other places, there were no guards patrolling, and no maids entering and leaving.

"Flowing Water Pavilion?" The arch of the courtyard hangs a plaque with gold letters on a black background.

"This is the residence of the Seventh Commander Xie Liushui, what, interested?I'll take you in to have a look..."Yun Ying saw Ye Xiao's thoughts.

"That's not good, Senior Xie lives here, he must be a person who likes tranquility, let's not bother. Ye Xiao glanced into the courtyard and said reluctantly. The peach trees in the courtyard are densely packed with more than one person high, and the winding paths are secluded. It is not how beautiful the scenery is, but the law of the distribution of peach trees, which makes Ye Xiao realize that there is a mysterious formation here. Ye Xiao inherited countless materials from Nangong Xingdou, and he also took the time to specialize, and now the way of the formation is not even a beginner, but his vision is already very human.

"It's out of the way, it just so happens that I have something to discuss with the Seven Commanders. Yun Ying led Ye Xiao into the Flowing Water Pavilion, "Follow my steps." ”

"It's really a maze!" Ye Xiao followed Yun Ying's pace closely, and walked in step by step, in his eyes, the distribution of those peach trees was the same everywhere, "If you don't go to the ground but fly over, or violently destroy these peach trees, won't this maze be useless?" Ye Xiao asked curiously.

"So this maze must cooperate with the no-fly formation, and this peach tree is just a trick. With a wave of her hand, Yun Ying blasted a peach tree to pieces, but after a while, the peach tree grew again.

"The Flowing Water Pavilion is actually a huge phantom array, and what you see in it is not necessarily true. It didn't take long for the two of them to come out of the maze and enter a bamboo building. The bamboo building is extremely simple, except for a bed and a table, there are various formation materials stacked. There is a painting hanging on the wall, in which an old man with a hat sits indifferently by the stream fishing, the hook is a straight hook, but he is wearing a large piece of bait, attracting countless fish to compete for food. It seems that he did not mean to fish, but to play with the fish. In the lower right corner of the painting is inscribed two lines of words, 'The heart is like a white cloud and is always at ease, and the meaning is like flowing water in the west and east'. A thin old man was standing at the table and was busy, completely unaware of Ye Xiao and the others. Yun Ying and Ye Xiao stood for a long time, and did not disturb, quietly watching the old man work, until the old man put down the utensils in his hand.

"The Great Commander is here, who is this one next to you?" Xie Liushui couldn't see, but he could distinguish many people and wild beasts just by the sound of footsteps, and at the same time, he was already happy, and with his soul perception ability, the world was clearer in his mind than ordinary people. There are various drawing tools on his desk, the most peculiar of which is a strange disc with a fire stone in the center, the disc has a unique golden shape, and mysterious symbols are written around it.

"He's Ye Xiao, Mr. Xie, how is the progress of the solar disk?" Yun Ying asked, her eyes full of anticipation.

"The conversion efficiency is only 200 percent, which is far from the theoretical value of 300 percent. Xie Liushui sighed dissatisfiedly.

"Two hundred percent is already very good, in the past, it took a fire stone to ensure that an ordinary person could survive the winter safely, but with this formation, the disc only needs half a piece. And the disc can be reused. This thing is related to the livelihood of hundreds of millions of people in our western region, and Mr. Lao bothered to bother. Yun Ying said gratefully.

From the conversation between the two, Ye Xiao heard the doorway, the seventh commander Xie Liushui used the way of the formation to make this sun disk, and this sun disk can amplify the effect of the fire and warm stone. Half a piece can play the role of one piece. If it is widely promoted, those poor people will save a lot of money. However, this is bound to encroach on the interests of White Tiger City, but the Desolate Sky Army does not care about White Tiger City's attitude.

"Can this formation disc be mass-produced?" Ye Xiao asked a key question.

Xie Liushui frowned, "The formation disc is made of the most ordinary brass, mainly the formation runes and the engraving of the formation route, at least the level of the formation apprentice is required." Although mass production is not difficult, it is a drop in the bucket compared to the hundreds of millions of people in the Western region. ”

"Can I take a look?" Ye Xiao looked at the disc in Xie Liushui's hand curiously, and Xie Liushui handed the disc in his hand to Ye Xiao without saying a word.

The texture of the copper ware is the beginning, and there is really nothing special in the material, but in addition to the hole in the center of the copper plate, the entire copper plate is engraved with dense thin lines, forming a precise pattern, just like the lines on the circuit board. There are also some mysterious characters engraved around the disc, which are the language of the array mage.

This world is bizarre, gods and demons and monsters really exist, and the physical laws on the earth have long been inapplicable, but it does not mean that this world does not have its own inherent laws, whether it is the way of refining, the way of formation or the way of elixir, all of them are a systematic knowledge system formed by people's cognition of this world. This world also has its own Newton and Einstein, which Ye Xiao recognized early on. What he was holding in his hand at the moment was a powerful proof that if the copper plate could be produced in large quantities, it would definitely change the status quo in the Western Regions (there are other ways to survive the winter elsewhere). This is the most powerful proof that knowledge is changing the world.

There is no problem with such a process to achieve mass production with high-precision instruments on the earth, but Ye Xiao did not learn this specialty, and with the manufacturing process of the wilderness world, he would definitely not be able to make those precision machines. The Three Realms may have his own way, Ye Xiao is out of action for the time being.

"I don't know if the Mo family in the fairy world has a way to mass-produce formation equipment...... Ye Xiao thought of the mysterious Tianqiong battle puppet and the Tiangang battleship, and the Mo family's technology should not be underestimated.

"Ye Shaoxia didn't know that the Mo family was extremely xenophobic, and they did a very good job of keeping technology secret, and it was difficult to get a way from them. Xie Liushui shook his head, how could he not know that the Mo family was superb.

This matter was kept in Ye Xiao's heart, and he would also study the way of the formation in the future, maybe he would find a good way in the future. Yun Ying also looked at the sun disc with a regretful face, if this thing can be mass-produced, it will definitely be a huge bargaining chip for the Desolate Sky Army to win people's hearts and benefit the common people.
