After playing all night, the four of them returned to Wansheng Academy. Liu Han and Mu Yan went directly to sleep, Chen Feng continued to go to class, and Yu Hao came to the back mountain of Wansheng Academy.

Still next to the small pool, Yu Hao took out the refining furnace and some other tools from the space ring. At this time, Yan Lao's illusory figure appeared on Yu Hao's side.

"Teacher!" Yu Hao shouted respectfully to Yan Lao.

Yan Lao nodded and said, "Today I will start teaching you to refine the sword, in fact, refining the knife can also improve the fighting qi and cultivate the physical fitness, especially your strength!"

Knife refining is an extremely hard process, and beginners who started just now, let alone ten refinements, will be tired enough even if they practice.

"Put the iron in the furnace first, wait for a certain temperature and then take it out, and then hit it with a hammer, remembering that the time of each blow should be urgent, and hit it a hundred times in a row. After you have the preliminary model, put it into the refining furnace again!" Yan Lao said slowly.

According to what Yan Lao said, Yu Hao followed suit. Put Fan Tie into the refining furnace, and wait for Fan Tie to burn red, which also requires a certain amount of time to wait, just enough for Yu Hao to cultivate Dou Qi.

Fan Tie was burning in the refining furnace, and Yu Hao was sitting quietly next to the refining furnace alone, Yan Lao was on the side, observing the Fan Iron in the refining furnace.

After a long time, Yan Lao said to Yu Hao: "It's okay, now you can take out Fan Tie, remember, beat it immediately after taking it out, the speed must be fast!"

Yu Hao nodded, didn't say anything, directly took out Fan Tie, and beat it with a giant hammer, the first ten hammers were fine, and Yu Hao didn't feel anything, but later forty hammers, fifty hammers, Yu Hao gradually felt that his strength could not keep up.

"Don't slow down, hold on, and play to your limits!" Yan Lao said to Yu Hao.

Yu Hao shook his teeth, exerted all the strength of his body, and kept gritting his teeth and persevering, ninety-seven hammers, ninety-eight hammers, ninety-nine hammers, one hundred hammers. After beating the hundred hammers, Yu Hao once again put the knife embryo that had begun to take shape into the refining furnace.

"Very good, let's continue to repeat this action, but you can remember one thing, the whole knife is a whole, some people refine knives by separating the blade and the hilt, but since you learn from me, then you have to use my method, the handle and the blade are made on a piece of iron, so that his artistic value can be reflected to the greatest extent!" Yan Lao said with a smile.

"The handle and blade are made together?" Yu Hao looked at Yan Lao in surprise, "Is this okay?"

If the handle and blade are built together, it will undoubtedly increase the difficulty a lot. After all, the handle and blade of the knife are used differently, and the number and method of forging are also a little surprising.

"How do you know if you can do it without trying, the weeping blood knife behind you was made by the old man in this way, can you see the difference between him and other knives?" Yan Lao said threateningly.

Yu Hao recalled that when the Weeping Blood Knife was used, it could perfectly exert its own strength, but when the ordinary knife was used, it could only exert part of the power that it originally used. But there are also drawbacks, the countershock force of the opponent's attack on the Weeping Blood Knife will be transmitted to Yu Hao's arm, and in general, there are pros and cons.

"The Weeping Blood Knife can perfectly transmit power, including the power used by oneself and the shock force caused by the opponent, in general, there are advantages and disadvantages!" Yu Hao said what he thought in his heart.

"What you say makes a lot of sense, but as long as you use it properly, this so-called disadvantage can be completely avoided!" Yan Lao said with a faint smile.

"How to avoid it?" asked Yu Hao curiously.

"Avoid hard encounters with opponents, hit opponents directly, maximize the advantages of the Weeping Blood Knife, and minimize the disadvantages!" Yan Lao said with a smile.

Hearing Yan Lao's explanation, Yu Hao instantly understood. At this time, the knife embryo in the refining furnace was almost at the end of the fire, Yu Hao took it out again, and beat it again and again according to the previous first method, and in the end, it was almost to Yu Hao's limit.

In this way, he has gone through seven or eight times of forging, and in the last few forging processes, Yu Hao suddenly found that he didn't seem to be as struggling as before, and his strength seemed to have improved a lot.

"It's finally done!" After ten refinements, Yu Hao's first knife made by himself has been born, and after being washed by cold water, a knife made of a piece of mortal iron appeared in Yu Hao's hand.

"What are you happy about?" Yan Lao on the side shook his head at Yu Hao and said, "The knife you punched out has no artistic value, and if you sell it in the market, you won't even be able to earn back the cost price!"

Hearing Yan Lao's words, Yu Hao's face showed an embarrassing smile, indeed there was no highlight in Yu Hao's hand, although the whole body was done in one go, but there was no beauty.

"Lose it!" Yan Lao said casually to Yu Hao.

Yu Hao looked at the knife in his hand, no matter what, this is the first knife that Yu Hao has created, and it has a different meaning for Yu Hao.

Yan Lao saw that Yu Hao had been hesitating, so he continued: "In the future, you will build a knife that is ten times better than this, or even a hundred times better!"

In the end, under the persuasion of Yan Lao, Yu Haoxin ruthlessly threw the unnamed knife into the pond. Ordinary sank to the bottom of the pool with a single sound.

"Refining a knife is an extremely energy-consuming thing, in the future, you will practice the sword one day and alternate between cultivating combat skills one day, so that you can save time and not collapse your body!" Yan Lao said slowly to Yu Hao.

"Well, I understand!" Yu Hao replied respectfully.

It was not early, Yu Hao returned to his compound, chatted with Liu Han and them casually for a while, and then went back to rest. Liu Han and the others also knew that Yu Hao was refining swords in the back mountain, but they all thought that Yu Hao was just a temporary interest and did not interfere with his freedom.

On the second day, Yu Hao got up and planned to go to class. Originally, Yu Hao needed to take a class with the dual attributes of ice and fire, but Yan Lao asked Yu Hao to go to the ice attribute instead of the fire attribute. Yan Lao told Yu Hao that he himself was a fire attribute, and Yan Lao could teach Yu Hao fire attribute things.

In fact, Yu Hao should have thought a long time ago that Yan Lao is a fire attribute fighting spirit, and only people with fire attribute fighting energy can refine swords, which is why Yan Lao didn't say a word about knife refining before, and it wasn't until Yu Hao had fire attribute fighting qi that he enthusiastically taught Yu Hao to refine knives.

As Yu Hao's teacher, Yan Lao hopes that Yu Hao can learn all his skills. As one of his proudest skills, he naturally hopes that Yu Hao can learn it.

"Yu Hao, where are you going to go out so early?" Mu Yan said with a smile after seeing Yu Hao, it is rare for Mu Yan to get up so early today. At the moment, he was sitting in the courtyard with Liu Han and chatting

"Go to class!" Yu Hao replied with a smile, and then walked out of the compound.

Liu Han and Mu Yan glanced at each other, and then Liu Han said to Mu Yan: "Chen Feng is cultivating so hard, and now Yu Hao is so desperate, he can't see anyone all day long, it seems that the two of us have to work hard!"

Hearing Liu Han's words, Mu Yan also nodded, "I think I'd better go to class too!" As he spoke, he had already taken action and immediately walked towards the door.

As for Liu Han, he has not yet broken through the swordsman, so he can only stay in the courtyard alone and cultivate.

Yu Hao went out and walked directly towards the building that belonged to the Ice Attribute Dou Qi, and the first floor belonged to those swordsman level students. There are about 10 classrooms on the entire first floor, and each classroom has a teacher who teaches the class, so you can choose a different classroom according to your preferences.

Yu Hao casually walked into a classroom and sat down in the back row early. There were still a few minutes or so before the start of class, Yu Hao sat in his place and waited quietly.

At this time, a person sat down next to Yu Hao, Yu Hao looked over unconsciously, this person had long blue hair falling to his shoulders, and he was wearing a light blue robe.

"Your name is Yu Hao, right? My name is Feng Ya!" the girl who had just sat down said to Yu Hao with a smile.

This girl was the Feng Ya who had eye contact with Yu Hao in that big classroom that day, but she didn't expect him to advance to the level of a swordsman so quickly, and she happened to have the same water attribute as Yu Hao.

"Hello!" Yu Hao said politely to Feng Ya.

"I didn't expect it to be such a coincidence, the two of us are both water attribute fighting spirits!" Feng Ya said to Yu Hao with a smile.

In fact, the girl with the water attribute is very temperamental, just like Feng Ya next to Yu Hao, the whole person seems to be as soft as water. There is a feeling of freshness that is difficult to describe in words, but it makes people feel refreshing.

Yu Hao nodded to Feng Ya, and at this time, a woman in her twenties walked up to the podium, wearing a blue power suit. It shows his full chest even more.

"This lecturer is also a student of our academy, Lan Xin, a student at the level of a great sword master. Most of the people in the academy who give lectures to swordsmen are students at the level of great swordsmen in the academy!" Feng Ya on the side explained to Yu Hao, he knew that Yu Hao was the first day of class and didn't know this lecturer, so he explained. Obviously, this is not the first time Lan Xin has come to class.

"Ladies and gentlemen, there are still a few days before the academy's qualifying tournament begins, if you want to sign up, you have to hurry up, today is the final deadline!" said Lan Xin on the podium to the students below.

Most of the students who want to sign up here have already signed up, and those who don't sign up are basically those who don't have any confidence in themselves. So when Lan Xin asked this, there was silence below.

"Have you signed up?" Feng Ya asked Yu Hao beside her, turning her head.
