Any knife needs to use Dou Qi to be able to recognize the master, because Dou Qi is a sign of becoming a knife disciple. People who can't even cultivate their fighting spirit are not qualified to use a knife, which is an insult to the knife.

"Recognize this knife!" Yu Hao looked at the knife on his back and muttered silently.

This knife was left to him by Yu Hao's mother, and when his mother died, he didn't even have a chance to tell Yu Hao what the name of this knife was.

This knife was the only relic left by his mother to Yu Hao, so Yu Hao decided to take him with him for the rest of his life. Now that he hears that this knife can recognize the master, that is to say, the relationship between this knife and Yu Hao can be one step closer, and Yu Hao is naturally very happy.

"I'm going to train, Yi Lao!" Thinking of this, Yu Hao's whole person came to motivation, and said to Yi Lao excitedly.

"Go, kid!" Yi Lao said with a smile as he looked at Yu Hao and smiled.

After getting Yi Lao's promise, Yu Hao rushed to the stone forest. This stone forest is the best for exercising Yu Hao's physique, but now Yu Hao only has three hundred catties of strength, and he can barely hold the war knife behind his back with both hands, so it is very difficult to use the war knife.

Training requires training with strength beyond one's limit, so at the beginning, Yu Hao chose a boulder weighing three hundred and fifty pounds for training.

Yu Hao's training course is very simple, nothing more than lifting a boulder to do some simple exercises, or even some running.

In the months that followed, Yu Hao kept doing the same thing over and over again. After a short rest in the morning, he entered the stage of training his physique.

It was another morning with fresh air, and Yi Xuan'er went to play after two hours of training. And Yu Hao is still standing there, constantly absorbing the power of nature in the air.

"What's going on?" Yu Hao suddenly felt a trace of strangeness, absorbing the natural power in his body when it flowed through the dantian position, it actually continued to hover in the dantian position, and it never dispersed for a long time.

Yu Hao controlled the flow of natural forces into the dantian, and finally stabilized after wandering in the dantian for a long time, and then these natural forces continued to converge, expanding and eventually filling the entire dantian.

After expanding to the extreme, these forces of nature gradually changed, as if they were compressed, condensing another strange energy.

"Could it be that this is Dou Qi!" Yu Hao felt the changes in his body in disbelief, and instantly Yu Hao felt that the dantian was completely mutated, and every time the natural power in the air flowed through the dantian position, the power would be transformed and transformed into this strange energy.

"Dou Qi, this is Dou Qi, I have finally cultivated Dou Qi!" Yu Hao shouted excitedly.

He clearly felt that the power in his body was the so-called Dou Qi, and with the Dou Qi, he could burst out with faster speed and more powerful power, which was why the gap between ordinary people and sword disciples was so big.

Yu Hao's cry also attracted Yi Lao and Yi Xuan'er. Seeing the subtle changes that occurred in Yu Hao's body, with the appearance of vindictiveness, Yu Hao's whole temperament became different.

Yi Lao nodded slowly at Yu Hao, and he could see that he was very satisfied with Yu Hao. "Child, you have finally taken the first step to become a strong man, but you must not be proud, you need to work harder in the future!"

Although Yi Lao's words were very bland, Yu Hao felt that there was nothing to it. But in fact, within a few months, he was able to cultivate his fighting spirit, and it was very fast to succeed in becoming a sword apprentice.

It takes several years for most people, but this is relative to a teenager who is about ten years old, but Yu Hao is almost fifteen years old, and he is already a beat slower than others, but fortunately, it is still too late to catch up.

"Yu Hao understands!" After listening to Yi Lao's teaching, Yu Hao seemed to nod in understanding. Becoming a knife apprentice is indeed a happy thing for Yu Hao, but he is now almost fifteen years old before becoming a knife apprentice.

But Yu Hao's younger brother was already a Demon Pupil apprentice when he was nine years old, and now he is probably already a Demon Pupil apprentice and is impacting the Demon Pupil level. So the gap between the two is still very big, and Yu Hao still needs to continue to work hard.

"Brother Yu Hao is so powerful, I haven't practiced for so long and haven't developed a fighting spirit, and Brother Yu Hao has only practiced a fighting spirit in a few months!" Yi Xuan'er on the side held Yi Lao's hand and said excitedly.

Since she was eight years old, Yi Xuan'er has been cultivating with Yi Lao, but her cultivation progress is not fast after three days of fishing and two days of drying nets, and she has not cultivated her fighting spirit for more than two years.

"You should also come on, but you can't leave your brother Yu Hao behind!" Yi Lao smiled when he heard what Xuan'er said, touched Yi Xuan'er's head and said.

Children are generally like this, and they always like to be lazy in their cultivation. But after all, Yi Xuan'er is only ten pairs, and it is still within the tolerance range if she has not cultivated her fighting spirit, not to mention that Yi Lao's discipline of Yi Xuan'er is not strict, and even spoiled. was reluctant to force Yi Xuan'er to cultivate, but because of Yu Hao's success, it played a certain role in urging Yi Xuan'er.

"I won't be left behind by Brother Yu Hao, I'm going to cultivate!" Yi Xuan'er pouted and said, stuck out her tongue and made a grimace at Yi Lao, and then immediately ran to cultivate.

As for Yu Hao, he walked to the position of the stone forest. The last time he trained, Yu Hao was already able to lift an 800-kilogram boulder, and even a 900-kilogram boulder could barely lift it.

But a sword apprentice can at least lift a thousand catties of boulders, so Yu Hao wants to see where his limit is after cultivating his fighting qi.

Yu Hao picked a boulder weighing 1,000 catties and held the boulder with both hands. But obviously, it was very difficult, the boulder did not move at all, and Yu Hao couldn't move the boulder at all, let alone lift it.

At this time, Yu Hao was using his strength, and the fighting energy from the dantian position poured out and flowed to Yu Hao's whole body. In an instant, Yu Hao felt that his strength had doubled, and the boulder in his hand had become much lighter. Slowly, Yu Hao lifted the thousand-pound boulder to the top of his head.

Yu Hao found that this was not his limit, he let go of one hand and held a thousand catties of boulder with one hand. A few seconds later, a touch of ecstasy appeared on Yu Hao's face, "Could it be that this is the strength of the fighting spirit, this is the strength of the sword disciples!"

Yu Hao's face was full of excitement, how could he have thought that as soon as he cultivated his fighting spirit, his strength would increase so much that he could lift a thousand catties of boulders with one hand.

Then, Yu Hao once again challenged the heavier boulder, and after several tests, Yu Hao found that his limit now is that he can lift a boulder of 1,800 catties, and the limit of one hand is 1,400 catties.

1,800 catties for both hands, 1,400 catties for one hand, this has far exceeded the level of ordinary knife apprentices, and the average knife apprentice is primary, and he only has the strength of 1,000 catties for both hands and 800 catties for one hand.

This may be because Yu Hao began to conduct physical training in the early years, and this time he successfully cultivated his fighting qi, which led to a thick accumulation, and his one-time strength soared.

At night, in Yu Hao's cabin. Because of the excitement, Yu Hao couldn't sleep.

Yu Hao sat on the bed, looked at the war knife in his hand, and remembered his mother. "Mother, I have finally succeeded, I want to prove to the world that I am not a waste, I will be your pride, I will avenge you, Mother, I will definitely be!"

Looking at the war knife in his hand, Yu Hao suddenly remembered what Yi Lao said about recognizing the lord before. Regarding the matter of recognizing the master, Yu Hao got a lot of understanding from Yi Lao.

The reason why you need to recognize the Lord only after cultivating the fighting spirit is because the blood that is not moistened by the fighting spirit is dead blood, and it has no vitality, and it cannot wake up the sleeping combat knife.

And after cultivating the Dou Qi, the cultivator's blood is nourished by the Dou Qi and becomes life, which is enough to awaken the battle knife and achieve the effect of recognizing the Lord.

Yu Hao's eyes wandered around this war knife, and he still vaguely remembered that his mother was holding this war knife in her arms, and she desperately escaped from the pursuit with Xiao Yu Hao in her arms and returned to Ke's house.

This war knife is connected to the hilt, and it is enough to reach the level of one meter six, which is close to the current height of Yu Hao, so Yu Hao has always carried it on his back. There are two rows of skeletons on each of the handles, and the skull's eye lens is bright red blood.

Yu Hao cut his finger, and a drop of blood seeped into the sword. At this moment, Yu Hao was extremely nervous, because he didn't know what would happen to his war knife next.

I only saw a flash of light at the position of the battle knife, and then the position of the entire blade underwent a transformation, and the surface of the blunt knife that had not been opened slowly fell off, and after a long time, the sharp blade appeared in Yu Hao's eyes. There was a faint chill from the knife.

"Is this really my war knife?" Yu Hao said dumbfoundedly, it was difficult to contain the excitement in his heart, but it was more of an unbelievable emotion, just from the surface of the knife, Yu Hao felt the extraordinaryness of this knife.

"It's not yours, who else will it be!" Suddenly, an old voice sounded in Yu Hao's ears.

"Who!" Hearing this voice, Yu Hao subconsciously held the war knife and looked around. He could hear that this was not Yi Lao's voice. But he seemed to remember that the valley was so secluded that no one else could come in.

"Don't look for it, I'm in this standing knife in your hand!"

The old voice sounded again, and Yu Hao was so shocked when he heard this that he immediately let go of the war knife in his hand, and the war knife slipped to the ground.

Yu Hao stood aside, looked at the war knife on the ground vigilantly, and said in fear: "Who are you?
