Tang Feng's cultivation of the unpredictable technique was not something from this world, so no one could guide him. Moreover, Tang Feng did not want to be someone else's apprentice for no reason, restricting his own freedom, especially when that person was Bai Xiaolou. However, he didn't know why Bai Xiaolou refused Auntie's proposal.

  "How can you..." Lin Ruoyu sighed with a bitter smile.

  "Lin Shijie." Bai Xiaolou's thoughts turned rapidly, and he opened his mouth to say: "Tang Feng's qualifications are quite good. These past few days, I've only been teaching him the cultivation method, without giving any guidance. I'll still be staying at Tianxiu for a while longer. If Tang Feng has any questions during this time, I'll definitely clarify them for him and won't hold anything back. As for taking on an apprentice... Xiaolou's experience is too shallow, he can barely take care of himself, let alone take on any disciples. Please forgive me, Lin Shijie."

  "Right, right, right!" Tang Feng nodded vigorously on the side.

  Lin Ruoyu glared at Tang Feng, then turned to Bai Xiaolou and said softly: "Since my junior sister says so, I won't force anyone either. Wind can't worship under your door, it's just that he doesn't have the good fortune."

  Lin Ruoyu knew that it was better not to force others too much. Bai Xiaolou had already taught Tang Feng the cultivation method and even given him precious spiritual pills, which showed that he valued Tang Feng highly. So, even if they didn't have a formal master-disciple relationship, it wasn't a big deal. Good things take time to develop, and she could slowly push this matter forward later. By then, even if Bai Xiaolou wouldn't accept Tang Feng as his disciple, bringing him into the White Emperor City would definitely not be a problem.

  Thinking of this, Lin Ruoyan no longer dwelled on the issue and instead chatted with Bai Xiaolou about long and short things.

  While they were chatting, Tang Feng quickly slipped away unnoticed.

  Let Bao'er get pen, ink, paper and inkstone for himself. Tang Feng started drawing a manufacturing diagram of a hidden weapon mechanism.

  Juxianduan's plot against Tianxiu has affected the balance of power among the three major families in Jing'an City, and even influenced the surrounding areas within a radius of thousands of miles. Although Tang Feng's sudden appearance had foiled their long-planned scheme, he was certain that Juxianduan would not let the matter rest.

  To be honest, Tang Feng himself didn't have any feelings for Tian Xiu. In the past, Tang Feng had been mistreated by others and was looked down upon everywhere in Tian Xiu, with only Lin Ruoyu showing him care and concern. When Juxianmen came to deal with Tian Xiu, Tang Feng didn't want to get involved. However, this was after all a place he stayed at, and it was also Lin Ruoyu's sect. If Tian Xiu were to be destroyed, Tang Feng himself wouldn't mind, he could just wander the four seas, but Lin Ruoyu would definitely be heartbroken, and who knows what kind of sinister plot might befall her.

  But before that happened, Tang Feng couldn't say it clearly either. After all, everything was secretly investigated by himself, and if he really said it out loud, no one would believe him.

  With the strength of refining the six realms, killing the four major high-level officials of the Liu family and forcing them to reveal this earth-shattering secret from their mouths, such a thing is simply a fool's dream.

  So thinking about it, Tang Feng could only prepare for the worst and help Tian Xiu increase his strength first. Of course, this favor couldn't be done for free.

  The strength of a cultivator is not something that can be easily increased at will. The simplest and most effective method is to upgrade their equipment!

  Who hung the two strips of blue and red, half red and half purple on the waist of heaven?

  Rainbow descends! Tangmen's hidden weapon spectrum ranks eighth, rainbow in the sky, fairy falls to the mortal world!

  Luo Xian Hong is a type of mechanical hidden weapon. Once activated, seven different colored flying needles can draw out a rainbow-like image in mid-air. Each color has seven needles, and 49 needles can be shot at once. The built-in needles can be fired three times. When the rainbow appears in the air, the enemy will have already been killed, leaving only a fleeting glimpse of beauty imprinted on their eyelids.

  Dark weapons, 80% of which are hidden and launched, the best way to make people unaware, so as to more effectively kill the enemy. However, Luoxianhong is a paradoxical mechanical dark weapon, its ejected flying needles will attract people's attention to the greatest extent, but also make people defenseless.

  Beauty often means danger, this is a fatal spell, this is brilliant death.

  Luoxian Hong's volume is very small, about the size of a child's palm, making it suitable for hiding. The Tianxiu Sect only has female disciples, and as long as they attach the hidden weapon to their arm, when needed, press the mechanism to launch it. This not only allows the Tianxiu disciples to better defeat the enemy during battle but also saves lives in times of crisis.

  Tang Feng could only do so much, if he was given enough time, he could turn Tian Xiu into an impregnable fortress like the Tang Family Fort of his past life, full of mechanisms and traps at every step. However, first, he didn't want to expose too many secrets, and second, the Giant Sword Sect wouldn't give him much time to prepare these things.

  Tang Feng finished drawing half of the blueprint and then went into the house to look for Lin Ruoyu.

  Lin Ruoying and Bai Xiaolou were discussing the way of cultivation when they saw Tang Feng running over with a piece of paper in his hand, and couldn't help but ask: "Feng, what's that you're holding?"

  "Tang Feng smiled and said: 'Auntie, I want to do a deal with Tian Xiu!'"

  Lin Ruo Xuan glared at him with a scowl, cursing: "You stinky little brat, what kind of business do you think Tian Xiu is? This is the place where I was born and raised, what business can you do to make Tian Xiu come and do it?"

  Tang Feng made a bitter face and said: "I'm so poor now that I have to think of ways to make some money."

  "Where is the money I gave you?"

  "All the flowers are gone." Tang Feng's face was full of embarrassment.

  "Where did you lose again?" Lin Ruoying stretched out her hand and knocked Tang Feng's head, then took out a 100-tael silver note from her body and handed it to Tang Feng.

  "No need, Auntie. It was because I wasn't capable before, but now I want to make money on my own." Tang Feng said seriously.

  "It sounds just like the truth." Lin Ruoyan smiled wryly and glanced at Tang Feng.

  "Let's see what he wants to do." These days of getting along, Bai Xiaolou also knew that Tang Feng was not the kind of person who would joke around on serious matters.

  Lin Ruoying coughed lightly and sat down in a chair, saying: "So, what business do you want to do with Tianxiu?"

  Although his tone was very serious, Lin Ruoyu's suppressed smile on his face clearly showed that he was in the mood to play with a child. Even though he knew Tang Feng might be teasing him, Lin Ruoyu still indulged him, which was the doting of an elder towards a younger one.

  "Auntie, please take a look!" Tang Feng walked up with quick steps, using three stresses in one sentence. He put the well-drawn blueprint into Lin Ruoyan's hands and then ran back with small steps, his hands hanging by his sides, standing respectfully, making faces at Bai Xiaoleng who was smiling with pursed lips.

  "Your handwriting is not bad!" Lin Ruoyu spread out the drawing paper and took a glance, only to see three big characters: "Luo Xian Hong". The strokes were bold and powerful, with a flair that didn't seem like Tang Feng's elegant and refined appearance.

  As she continued to look down, Lin Ruoyu's smile instantly retracted, her pretty face became solemn, and her beautiful eyes scanned the drawing paper up and down, not missing any details.

  When White Xiaoleng saw Lin Ruoyu's expression, she also curiously stretched her neck to take a look. However, she was separated from Lin Ruoyu by a tea table and only caught a glimpse of it. Even that little bit of content made White Xiaoleng so shocked that she almost dropped the teacup in her hand.

  It was a design drawing of an extremely precise component, just one component, but it was designed with extreme ingenuity.

  Lin Ruoyu put away the drawings in her hand and looked at Tang Feng, asking: "Where's the other half?"

  Luoxian Hong's drawings, Tang Feng only drew half of it, and it was the first half. The most critical second half, Tang Feng didn't draw at all. After all, it was for business purposes. If he had drawn everything, his aunt would have taken it away with a wave of her hand, saying "Let me study this thing!" By then, Tang Feng wouldn't even have anywhere to cry.
