After a simple wash, after breakfast, Yang Tong hurried to a remote alley located in the east of Qingshan City.

Compared to the downtown area in the center of the city, it is relatively deserted.

At the end of the alley, there is a shop, the door is full of birds, the decoration looks very ordinary, and even tattered, as if it has been corroded by the years, only the torso is still standing, and the name of the shop is also very vague, and the word iron shop can be vaguely seen.

Yang Tong knocked on the door cautiously, for fear that the door would collapse in the next second.

There was a creak, and the door slowly opened.

A teenage girl walked in front of her, her little face was flushed, a pair of big eyes were bright, revealing a row of neat teeth, like pearls, and she was dressed in pale yellow clothes, which set off the girl's cuteness to the fullest, and there was a jade pendant engraved with Luo characters on her waist.

The whole person is out of place with the surrounding environment, so I guess which lady should it be, right?

"Who is Big Brother looking for?" the clear voice sounded like a silver bell, which made people very comfortable.

"May I ask Lu Song, is Master Lu here?" Yang Tong said unhurriedly.

"Oh, you look for Grandpa Lu, but Grandpa Lu said that he will not pick up customers today. ”

"Little sister, so you tell Master Lu that the old man is visiting. Yang Tong said with a smile.

"Hey, I'll ask, you wait here for a while, but you can't see it, it's none of my business!" said the girl, surprised.

After saying that, he walked to the backyard.

Yang Tong looked at the weapons and farm tools on the iron shelves in the store, thinking that it was from the hands of this Master Lu, so he took one casually and played with it.

"Hey, the impurities of these iron tools have been removed to at least seventy percent. Yang Tong was extremely shocked in his heart.

As we all know, the training tool has to be refined, extracted, burned, and finally formed, and the quenching is the most difficult in these steps, because to complete a high-grade weapon, it is a standard to make a mineral reach at least seventy percent of the purity, otherwise when the runes are burned later, even if there is nothing wrong with the burning, it will also lead to extreme instability of energy, resulting in a big explosion, and the energy of a high-grade weapon explosion can blow up a high-grade source nuclear realm without even the scum left.

The most rare thing is to use an ordinary piece of iron, which can temper the purity to such a high level, ordinary minerals, can not withstand refining, the internal structure is too fragile, even when Yang Tong is in another world, although the method of practicing weapons is different, but quenching is also an essential step, and I have never heard of anyone who can use a piece of mortal iron to achieve this level.

Yang Tong couldn't help but be a little curious about this Master Lu.

Yang Tong played with it, and an old voice suddenly sounded, "Could it be that Xiaoyou also knows how to refine weapons?"

Yang Tong put down the things in his hand, turned around and looked at the source of the sound.

I don't know when there are three more people in the store, the one who spoke was an old man, the old man had a short and hard mustache, slightly sunken eye sockets, a pair of dark brown eyes, a plain white cloth coat, full of silver hair also looked radiant, next to him was just the small, the little sister also naughtily winked at Yang Tong, the little hand also held a hand like a soft wattle, the skin was like a jade hand like condensed fat, the owner of this pair of jade hands was dressed in a plain white brocade clothes, elegant but a little more dusty temperament, a light blue thin belt to close the waist, showing a slender figure, hair casually draped on the shoulders, but added a bit of elegance, There is also the same jade pendant engraved with the word Luo on the waist, the only regret is that the green veil on the face blocks the girl's beauty.

Yang Tong looked at it and bowed to the old man.

"I know a little, but I'm not proficient, I guess this is Master Lu. ”

"The old man doesn't remember that there is such an old friend as Xiaoyou," Master Lu also looked at Yang Tong.

"Outside Jingting Xuanyu, the smoke and water are prohibited," Yang Tong said with a smile.

"You, you, you, where is he, is he okay?" Master Lu rushed to Yang Tong with a brisk look on his face.

"I don't know if I can take a step to speak. Yang Tong was still smiling.

"Oh, yes, yes, it's the old man who is confused, please talk about this little friend, purple smoke girl, now the old man, I have some important things to talk about with this little friend, I won't send you, go back to your old man and say, one day the old man feels that his body is rusty, and he wants to go out for a while, and he will definitely visit as soon as possible." Master Lu touched the little girl's head and said, "Zixuan, listen to your sister more, don't be naughty." ”

Zixuan said with a reluctant face: "But people are reluctant to let Grandpa Lu stay for a while, okay?"

"You little ghost, don't think that the old man doesn't know what you're thinking, isn't he just afraid that he won't be free when he goes back? But you've been here with me for so long, and if you don't go back, I'm afraid that your father will come and tear down my temple, hahaha!"

"If he dares, I'll beat him" Zi Xuan waved his pink fist and pouted, so cute.

"Hahaha, okay, go back with my sister, remember what your grandfather taught you, you have to practice every day, and I will come to check it. Master Lu touched Zixuan's head with a doting face.

"Okay Zixuan, it's time for us to go" A crisp and pleasant voice sounded in his ears, and Ziyan whispered, "Master Lu, I've made trouble for you during this time, so we'll set off." ”

After speaking, he pulled Zixuan and walked out slowly.

"Grandpa Lu, goodbye!" Zi Xuan said reluctantly.

Master Lu waved his hand.

When passing by Yang Tong and me, Zi Xuan also made a grimace.

Yang Tong shook his head with a smile, this little girl is quite funny.

"Little friend, don't mind! this girl is like this, she doesn't mean anything else. ”

"Master, you think I'm too stingy, cute girl, there are always some privileges, don't you?" Yang Tong said helplessly.

"Hahaha, it's me who is wrong, come to Xiaoyou, please, let's go in and talk about it. ”

......

"Sister, I've never seen Grandpa Lu's expression, who is that stinky villain?" Zi Xuan said as he looked at his sister with his little head.

Qianqianyu's fingers lightly tapped Zixuan's little head, "How can you say bad things about others behind your back?" I don't know, but I'm sure this person is very important to your Grandpa Lu." ”

"That's right, stinky scoundrel, if he doesn't come at this time, I can play for a while longer, hum!" Zi Xuan pouted.

"You see that you are like a puffed bag now, even if he doesn't come, you should go home, my father and mother have missed you for so long, and there are some urgent matters in the family that need to be dealt with, and you must go back as soon as possible. ”

"Sister, is it that old bastard again, forcing my sister to marry?"

"Little sister can't talk nonsense, no matter how you say that he is also a great elder, but marriage, if I don't want to marry, no one can force me. Ziyan's tone gradually became a little cold, and his cold eyes made people feel no trace of temperature.

......

In the backyard of the blacksmith's shop, under a huge osmanthus tree.

Two people, an old man and a young man, sat at a round table.

"You, you mean, he's gone?" Master Lu's tone trembled slightly, and he couldn't believe it.

Yang Tong took a sip of tea, put down the teacup, took out a letter and a key of unknown material from his arms, put them on the round table and handed them to Master Lu.

"Look, he told me to pass it on to you, and he said you understand everything after you read it. ”

Master Lu opened the envelope, his hands trembled, "That's right, this is the handwriting of the junior brother."

The more Master Lu looked down, the more his hands trembled, and the old tears were rampant, "I should have thought that it was him, but how could he do it!"

"Let Xiaoyou smile, people are getting old and old, and they can't stop crying, and they haven't asked Xiaoyou's name yet, what does it have to do with my junior brother?"

"Master is polite, my name is Yang Tong, Brother Lin is kind to me, the purpose of my coming here this time is this matter that he entrusted me. Yang Tong said with emotion.

When he came to this world, Yang Tong's whole person was confused, and he inexplicably returned to the state of his teens, a body of heavenly power turned into nothingness, and he had no power to restrain the chicken, the most terrifying thing is the influence of the laws of this world, the previous exercises, can not be cultivated at all, let alone rely on spiritual power of combat skills, that time was muddy, like a walking corpse, the most shameful can even be called the biggest stain on Yang Tong's life, because he was handsome and almost caught by a female bandit leader to be a child husband, if he was not rescued, he couldn't imagine his future life, thinking of our Yang classmates, his face was a little unbearable。

"He saved me, and taught me how to open my pulse, and when I met him again, before I could thank him properly, it was too late, and when he was dying, he entrusted me with these two things, and if there was anything that could be done to make a difference, just tell me, after all, he was kind to me. ”

"Alas, there are very few people like Xiaoyou, but this is the old man's family matter, so let the old man finish it himself. Master Lu looked much older, "Then what is Xiaoyou's plan next?"

"Lewd development, cough cough, just break around, take a look, by the way, Master Lu, do you know what is going to happen in this city, how did so many people gather?"

"Oh, you said outside, don't you know? In seven days, it will be the fourth college examination. ”

"Well, what is the Fourth Academy Exam. ”

Master Lu looked at him in surprise and said, "You don't know what the Fourth Academy Examination is", and looked at him with a little meaning, "You are from Biansai, and it is normal that you have not heard of it, and the old man will help you popularize the knowledge of this world." ”

"This world has five continents, and the geography of each continent has created different cultures and cultivation systems. I won't go into too much detail here, but you'll know when you have the opportunity later. What I want to say is that the continent we are located in is called the Eastern Xuantian Domain, and the territory is vast and immense, and it is subdivided into four regions. ”

After a pause, Master Lu took a sip of tea, moistened his throat, and said "" These four regions are the extremely cold land in the north, the Mohe in the east, the Yulin in the west, and the southern wilderness where we are now, each region has an absolute top overlord force to rule, and there is a more appropriate saying, six sects, one academy and eight families, which is the world's top power, I will talk about the first institute, as the name suggests, is the meaning of the academy, located at the junction of the four regions, called the Sifang College, also known as the four colleges, with perfect training and learning methods, teachers and students are very rich in resources. It is a holy place of learning in everyone's hearts, and everyone who comes out of it is the object of coaxing by all forces, even if it is a pig, as long as it comes out of the four courtyards, it is fragrant. ”

"Is it so terrifying? Then, according to you, other forces can tolerate such an existence?"

"This is also based on the attitude of the academy to maintain neutrality, never mixed with disputes between big forces, and there is another very important point, the students of the academy are all over the world, it is no exaggeration to say that even if a huge snobbery, more than sixty percent of the high-level are graduates of the four colleges, if you want to move this behemoth, you may need to weigh the anger from all directions! And this four-academy examination is prepared every three years for people under the age of 20 in the mainland who have arrived at the source core realm, which can be called a great prosperity in the mainland, the examination system is very strict, bringing together countless Tianjiao in the mainland, but only a few hundred people can really enter the academy, and the subjects of each examination are also inconsistent, generally send the tutor of the academy to each region, screen and select, and then unify into the four courtyards for the final trial, and those people outside are waiting for the people from the academy to screen. ”
