To make hidden weapons, mix poisons, and set up mechanisms, you need to be calm, get rid of distracting thoughts, and achieve the best results in one go. Just like the impact of a cultivator's retreat, if you can't break through the bottleneck once, and when you hit it again, you will plant a mental addiction, and you will involuntarily worry about failure, so that a cycle of evil surnames will be formed, and if it continues for a long time, it will be difficult to survive.

Seven days passed in the blink of an eye.

Lin Xiaotian stayed in the weapons room all day, admiring the weapons, this person is indeed a martial idiot, in addition to playing tricks and talking vulgarly, but also has a bit of perseverance, every morning together in the courtyard to practice swordsmanship, not to mention anything else, only his set of mystical moves, but it is overbearing and extraordinary, incisive.

Zhu Bufan's father and son continued to create devices for Tang Fei, and at Tang Fei's request, they invited his close friend Master Zhang Huaijin, who was a master carpenter as famous as Zhu Bufan. Tang Fei spent 20,000 taels of silver to buy a piece of century-old mahogany from his house, which is extremely light in weight, extremely hard and tough in toughness, and can be regarded as a good material for the main body of a large machine.

Except for the first day to see the master carpenter, who had to temporarily put down his work, for the next six days, Tang Fei stayed in the room, sleepless, and when it was time to eat, he took two bites to deal with the matter.

At this moment, it was the seventh noon, in Tang Fei's room.

"Senior brother, let's rest for a while, how can my body stand it if it goes on like this..."Bao'er put away the early morning tableware and found that she still hadn't moved, and she was extremely worried.

Tang Fei was already paralyzed by the question, so he didn't answer, he just cared about fiddling with these good parts, his face was pale at this time, his eyelids trembled slightly, he obviously lacked strength, and without the support of internal strength, he only relied on his physical strength to sleep for seven days and six nights, which was indeed very human.

Tang Fei frowned, as if he was dissatisfied, and said to himself, "Hey... There is still no good material, I'm afraid this 'meridian box' can't be made..."Tang Fei was extremely depressed, in a bad mood, holding the table with both hands, and sighed for a long time.

Bao'er saw that he was upset, and comforted him softly, "Senior brother, take a rest, let's find materials after resting..."

Tang Fei shook his head with a wry smile, turned to face Bao'er and said, "But it's me who is greedy for quick success, this is the top 20 hidden weapons on the 'Hidden Weapon Baijie', I know that I can't touch it in my current state, and there is no one in a hundred, so I will lower the materials one by one by a few grades, just to cope with this predicament, if I can find good materials in the future, I can make this thing..."Speaking of this, Tang Fei shook his head and smiled bitterly, and continued, "But I am greedy, even if I will' The difficulty of the meridian box has been reduced by a hundred grades, and the required spring components are also peerless materials above the Xuantie level... Hey..."

Bao'er seemed to be puzzled, "Xuantie? I've never heard of it, but I've heard of 'Tiantie'..."

Tang Fei immediately came to his senses and thought, "Most of the names of things in this world are the same as those of the original world, but some of them are different, just like the 'Tiger Thorn Flower' is called 'Tiger Tail Grass' here, and the stainless steel crystal is called Stainless Steel Stone here, maybe this dark iron is also called different. He asked, "Who have you heard, and where have you heard about it?"

Bao'er frowned and recalled, after the tea time passed, she still frowned, and said ashamedly, "Senior brother, I really can't remember, I just feel very familiar, as if I have heard someone say ......"

Tang Fei was depressed, and held back a smile and said, "Heh~, Bao'er doesn't have to blame herself, tell me when you remember..."

After that, Tang Fei turned his head and continued to assemble the parts on the table, and asked casually, "Lin Xiaotian can still be safe?"

It's not that Tang Fei despises Lin Xiaotian, it's just that the goods are causing trouble, a few days ago, he went out and said that he smashed a gambling house, and was beaten into a pig's head and ran back, if it wasn't for Zhu Bufan's protection, he was afraid that he would have been beaten to death, and two days ago, he made a big fuss in the county government, and the officers and soldiers surrounded the Zhu family's iron shop into an iron bucket, saying that they wanted to convict him of disturbing the public court and insulting the court officials, and he would be put in prison. The head catcher who came to arrest people was an acquaintance with this Zhu Bufan, and he gave face, and only counted the 20 kills of the goods as a punishment.

Bao'er didn't have a good breath and said, "Hmph, if he wasn't beaten into a pig's head, I'm afraid I'm going to go out and make trouble again, senior brother, when he is well, take him away...".

Tang Fei turned the corners of his mouth up, put down the device in his hand, put the ring in his right hand lightly to his mouth, thought about it, and replied, "Call him in..."

Bao'er was behind him, and he couldn't see the expression on his face, or he might be angry, this Lin Xiaotian was so troublesome, but Tang Fei was so pleased and appreciative.

"Oh... I don't know if the pig's head is there, I'll go and see..."Bao'er obediently took the order and left.

After a while, the door popped open, and it was about to fall off with a slight click, followed by a strange scream.

"Ahhh What do you want Lao Tzu to do...... Huh, why did you become a beggar for food, your hairstyle is quite good, ah, what is this, let Lao Tzu see..."As soon as Lin Xiaotian entered the door, he shouted and screamed, and was even more attracted by a few small close-fitting machine brackets that had been assembled on the table, and he was about to take a shot to grab it, but as soon as he took a step, he settled down in a golden rooster reading posture.

"Knock knock~" three sounds, where it lifted its feet and fell, there were three steel needles inserted, the needle was three inches long, about five cents in diameter, the steel needle was gray, and it was not a good thing at first glance. In addition, the tip of the tip is shining with a cold light, and if this foot goes down, it will definitely poke out three holes.

That was in the inn, Lin Xiaotian only knew that the three disciples of the Xuanzong were killed by Tang Fei, but he didn't know how he killed him, Tang Fei was already seriously injured at that time, and there was no trace of Xuan Qi fluctuation on his body, how to kill three Xuanzong at the same time from ten meters away, and the three of them died so strangely.

Lin Xiaotian put down his feet and looked at Tang Fei.

I saw Tang Fei sitting on the stool, hooking the corners of his mouth, smiling lightly, his left elbow on his knee, palm facing up, leaning forward, because he was bare-chested, he could see clearly, on the inside of his left arm, there was an iron square five inches long and two inches wide, this thing was completely black, rectangular, with three holes at the top, with an aperture of about 5 minutes, and two hubs at the end, one high and one low, which was very weird.

Lin Xiaotian frowned, the five fingers of his right hand were spread, his thumb scratched his ear hole vigorously, and his entire big hand shook 'without grinning'. Confused for a while, he immediately squatted down, grabbed a steel needle and observed it carefully, and kept squirting dirty words in his mouth.

Only then could I see that the lower half of the steel needle had just sunk into the floor, so the length was misestimated, it was a full five inches, and both ends were pointed.

"Ding~" Lin Xiaotian shook the steel needle away like an electric shock, "Ah...... Damn, what kind of deflated calf thing?", he only felt that the whole palm of his hand was numb, and then he couldn't exert force, as if the whole palm was not his own, and finally he was completely out of control.

Tang Fei shook his head and smiled, "You need to recuperate from your injuries recently, don't use this left hand first, well, 'Ma Xiansan' will be lifted by itself after three days, you don't have to worry...",

That Lin Xiaotian took out his Xuanxin knife, holding the knife in his left hand, Tang Fei thought that he was a left-hander, this thing was causing trouble all the time, and controlling his left hand was ......
