Three days later.


    The repair of the three-star Sabre has been completed. In the laboratory, the buzzing sound of the sword came out, the sword in the energy pool was sharp, the implanted fire energy crystal fluctuated not yet stably, and the sword body trembled constantly, as if it was going to fly.


    The master of my hometown Qiu tried it. The power of this Sabre is 20% higher than before.


    This situation made old Qiu''s family very happy. Despite his weakness, he invited master bassac to give a banquet in the main hall of Qiu''s family.


    "Mr. bassac, I won''t go. I''ll sort out the information here," Lin Chuan said.


    Master bassac nodded. The mechanics didn''t like socializing. He didn''t want to go to the banquet unless Qiu''s hometown invited him.


    "You mechanics really don''t know how to communicate..."


    The old owner of Qiu smiled and said, "look at Lin Chuan''s eyes, full of appreciation.".


    Lin Chuan has hardly slept these days. He has been in the laboratory all the time, which makes Qiu''s home owner sigh that he has such excellent talent in the field of machinery and works so hard. No wonder master Barcelona values him so much.


    From time to time, master Qiu said in front of master bassac that it''s a pity that Lin Chuan''s Kendo talent, if he explodes his liver like now, maybe in a year or two, he can get the essence of his unique sword skill.


    Master bassac doesn''t agree with this. In a year or two, Lin Chuan''s mechanic level may have reached four stars. He doesn''t have the time to learn sword skills.


    "Let''s use my study. It''s quiet and the environment is good..." said old Qiu.


    Lin Chuan nodded, took the light screen, entered the study, sat at the table and read the materials.


    This three-star weapon repair has benefited him a lot.


    It is not only the structure of the three-star Xinyuan arm, but also a special mechanical circuit. Over the past few days, Lin Chuan has many ideas for this special mechanical circuit.


    If this mechanical circuit is improved, it may be applied to the shadow of virtual bones to improve combat effectiveness.


    "If it can be used, the real combat power of [shadow of virtual bones] is enough to crush the strong ones below the four borders and three sections. My cards will be stronger..."


    Lin Chuan thought about how to improve this special mechanical circuit while doing calculations.


    Suddenly, Lin Chuan felt a strange fluctuation and looked out of the window. On the side of the stone tablet, Qiu Jinxuan''s body trembled slightly and his forehead exuded sweat.


    With Lin Chuan''s eyesight, you can clearly see the surface of Qiu Jinxuan''s body, which is swimming like a thin snake, and a trace of sharp sword Qi overflows.


    The sword Qi is very weak. If Lin Chuan''s sensing power is not extraordinary, it would be difficult for others to detect it.


    Of course, if old master Qiu is here, he will be aware of it with his keen sword sense.


    "Is this to be understood?"


    Lin Chuan looked at it and frowned slightly. Judging from the state of autumn Jinxuan, he was still a little short of understanding the sword marks on the stone tablet.


    "Forget it, since you are a collaborator, give him a hand..."


    Thinking like this, Lin Chuan runs [spiritual energy], and the pattern of forehead and eyeball appears, emitting his understanding of the stone tablet sword mark with a trace of spiritual energy.


    Immediately, Qiu Jinxuan only felt a slight pain in his head, and then a cool breath was injected from the top, and his understanding of the stone tablet sword marks was suddenly thorough.


    Hum


    There seemed to be a sword ringing in his body, echoing in his mind. Qiu Jinxuan opened his eyes with ecstasy in his eyes.


    Stone tablet sword mark, he fully understood!


    The master''s unique sword skill, he is really a beginner.


    This means that Qiu Jinxuan''s identity has changed from an alternate successor to one of the heirs.


    Take a deep breath. Qiu Jinxuan looks around. There are more than a dozen young masters of the Qiu family who are understanding. At this time, he can''t make a statement.


    "I can''t reveal this until the old master makes an assessment two days later. Otherwise, if Qiu Gucheng knows about it, he may arrange a killer and be desperate to harm me..."


    Qiu Jinxuan thought for a while, then closed his eyes and silently figured out his sword skill.


    In the study, Lin Chuan nodded and was very satisfied with Qiu Jinxuan''s response. If the latter jumped up and publicized it as soon as he realized it, such a person would have a worrying prospect as the owner of the Qiu family.


    Immediately, Lin Chuan buried his head again and began to sort out the data and calculate


    Time goes by and night falls


    Around the stone tablet, there are fewer and fewer autumn family children who understand. The banquet in the main hall continues. They all went to the banquet.


    Qiu Jinxuan also left. When he heard the news of the Main Hall banquet, he thought he might get to know Lin Chuan by taking this opportunity.


    In the yard, only Qiu Gu sat there, closed his eyes and understood, just like a sculpture.


    "Finally they all left..."


    Qiu Gucheng opened his eyes and swept around. There were only a few attendants in the yard, and no one paid attention here.


    Immediately, he took out the top thinking sharp medicine, drank it quickly, then closed his eyes, settled his mind, and tried his best to understand the sword marks on the stone tablet.


    This move has been clearly seen by Lin Chuan, who has been paying attention to it. He is waiting for this moment


    "Finally."


    Lin Chuan smiled and passed the [spiritual energy] silently.


    Suddenly, Qiu Gucheng only felt that his head was suddenly clear, and his past memory was very clear at once.


    The stone tablet and sword marks engraved in my mind are also extremely profound. It seems that I can grasp a deeper level


    "[top mind sharpness potion] is it so effective? It takes effect so soon..."


    Qiu Gucheng couldn''t help but be surprised. Knowing that the opportunity was rare, he quickly restrained his mind and understood it wholeheartedly.


    Seeing this scene, Lin Chuan laughed to himself. In this trace of spiritual energy, there was no understanding of the stone tablet sword mark, but simply refreshing.


    On the effect alone, even the [intermediate thinking acuteness potion] can''t compare with it. However, when the [spiritual energy] penetrates into the brain, the feeling of clear thinking is too strong to produce such an illusion.


    Qiu Gucheng wants to use this to thoroughly understand the sword marks on the stone tablet. I''m afraid it''s very difficult.


    Lin Chuan has seen the enlightenment progress of the strong young people in the autumn family these days. The most promising thing is Qiu Jinxuan.


    As for the others, it''s a lot worse


    "So, I''ll try the effect of [top thinking sharp medicine]."


    Lin Chuan whispered secretly, took out the "true" medicine and killed it in one bite.


    Hoo


    The forehead is slightly swollen and painful, the eye pattern directly appears, and the pendulum pattern on the chest also appears, which quickly gives full play to the effect of the medicine.


    Immediately, Lin Chuan felt that his thinking was dozens of times clearer than before. There were still some astringent problems just now, which were solved at once.


    "It''s worthy of being a [top-level thinking sharp medicine], which is several times stronger than the advanced effect! Limited edition, after all, is the truth of limited edition..."


    Lin Chuan buried his head again to calculate the special mechanical circuit, and the calculation formulas floated on the light screen. This time, the difficulty of calculation was significantly reduced.


    For a long time——


    He breathed a sigh of relief and finally improved the special mechanical circuit. Although he could not adapt to the degree of four-star Xinyuan armed, it should be feasible to equip it on the [shadow of virtual bone].


    Lin Chuan was very happy to think that the combat power of [shadow of empty bones] had improved again. He turned to look out of the window and found that Qiu Gucheng was still there to understand.


    "Does this guy think the efficacy is not over yet?"


    Lin Chuan frowned slightly and found that the efficacy of his medicine began to weaken, but there was still some time before the end of the efficacy, so he began to figure out the stone tablet sword marks. Don''t waste this precious medicine.


    For a moment, the eyeball pattern on his forehead kept rotating, and the sword marks on the stone tablet appeared in his mind. They were disassembled and reassembled one by one.


    On the surface of Lin Chuan''s body, a light sword light appeared and hovered continuously. It seemed that the sword light was going to penetrate his body at any time.


    At this time, Lin Chuan woke up and noticed his own state. He couldn''t help frowning. He had such a thorough understanding.


    This insight is not only the sword technique of stone tablet sword marks, but also a further one. The eye pattern directly promotes the further sword technique.


    Master Qiu''s beginner sword skill is advanced!


    "Three swords cut the Legion. If this sword skill is successful, it is really powerful!"


    Lin Chuan watched the body change and immediately condensed into a materialized spiritual energy membrane to isolate this situation so as not to be noticed.


    After a while, the sword light gradually dissipated. Lin Chuan looked out of the window. In the autumn of night, Gu Cheng still sat there and understood the sword marks on the stone tablet.


    "Well..."


    Lin Chuan frowned and had an idea.


    Ding!


    The sword Qi lingered around the fingertips, and then injected a trace of materialized spiritual energy, which fused together to isolate the sharp edge of the sword Qi.


    With a flick of his fingers, the sword Qi was emitted and quietly integrated into Qiu Gucheng''s body.


    Immediately, Qiu Gucheng''s body trembled, suddenly opened his eyes, drank a light sword Qi from his body, and made a light sound in the air.


    Looking at him, a faint sword scar gradually disappeared. Qiu Gucheng stared at him with incredible.


    During the enlightenment, the sword Qi in the body becomes self-contained. This is the unique sword skill of old Qiu''s master. It is a sign of stepping into a deeper level.


    "I not only thoroughly understood the sword marks on the stone tablet, but also went further? The sword Qi in my body breaks through the air and becomes a mark. This is the sign that the old master''s unique sword skill is really getting started..."


    Qiu Gucheng was overjoyed. Looking at the stone tablet sword marks, he only felt that he had never been able to clearly grasp the profound meaning of these sword marks like today.


    That is great!


    With this understanding, the heirs of the autumn family will give up who they are!


    Qiu Gucheng laughed twice and was so surprised that he looked around. There was no one else except the two attendants in the distance.


    Get up, Qiu Gucheng didn''t stop and left quickly.


    In the study, looking at Qiu Gucheng''s back, Lin Chuan smiled. The spiritual energy integrated into the sword Qi has the function of spiritual hint, which makes Qiu Gucheng think he has understood the deeper layer of the stone tablet sword mark.


    "This guy seems a little proud. Let''s see what happens next. It''s best to contact the black net organization in nanluo city and explore the reality of the black net organization here..."


    Lin Chuan whispered to himself.


    Back in nanluo city these days, although Lin Chuan knows the stronghold of the black net organization here, he has not taken further action, that is, he doesn''t know the truth.


    Different from the white dwarf Kingdom, the strength of the black net organization of the Star Austrian Empire is strong. Lin Chuan is alone and in-depth. He should have a complete grasp and decide after planning.
