At this time, Dugu Yu in the room only felt that his blood was surging, and he quickly sat cross-legged and ran his internal qi.

"This is about to break through!"

Dugu Yu didn't have time to think about it, and suppressed all the absorbed aura in the dantian.

After a "pop", the dantian barrier was broken in an instant, and countless spiritual energy surged.

Just as he broke through, the pot had already exploded outside. I saw that countless spiritual qi frantically converged, forming a vortex of spiritual energy in the air.

"Someone is breaking through!" Lu Yuanfeng felt the aura and hurriedly ran to the courtyard.

There were already a few people standing here, and when they saw him come out, Tong Yan said hello and stopped talking.

"It should be the dormitory of Dugu Danshi, looking at the situation, I don't know that I think someone has broken through the mountain realm. Steward Liu looked at the aura vortex and sighed.

"It's really amazing!" Tong Yan's aunt Tong Moran also sighed.

"Brother Dugu's talent is amazing, and it is reasonable to have such a power when he breaks through, you must know that some demonic geniuses will even descend on the Heavenly Tribulation when they break through......" Before Tong Yan's words fell, she saw that the sky was suddenly covered with dark clouds, accompanied by bursts of thunder.

"Heavenly Tribulation!" several people in the courtyard exclaimed at the same time.

Not long after, a thunderbolt fell from the sky, slashing directly at the bedroom where Duguyu was located.

In an instant, the top floor of the dormitory turned into powder, and with a "boom", the rest of the building collapsed, and a figure leaped out of it.

"Wow, what's the situation, I've just broken through and I'm about to be struck by lightning!" Dugu Yu was smoking at this time, and looked at the sky with some dissatisfaction.

At this time, he was a little afraid in his heart, you must know that he had just broken through the Qi Refining Realm, and before he had time to be happy, he had a sense of danger, and then he was struck by a lightning bolt, fortunately, the power of the thunder was not very strong, otherwise this blow, he might die.

"Brother Dugu, don't be careless, the clouds have not dissipated yet, I'm afraid that there will be thunderstorms, you have to be prepared. Lu Yuanfeng hurriedly reminded him, afraid that Duguyu would be seriously injured accidentally.

As soon as he finished speaking, a thunderbolt fell. This one was obviously stronger than the blow just now.

"Come back!" When Dugu Yu saw it, he secretly shouted that it was not good, and he raised his sword to block it.

With a "boom", he was knocked to the ground by the thunder.

"Ahem!" Dugu Yu coughed and struggled to get up from the ground, at this time his body was full of lightning, obviously this blow was not lightly injured.

"I didn't do anything bad, why did you hack me!" Dugu Yu was angry, looking at the sky and said dissatisfiedly.

I saw the clouds rolling, as if brewing the next blow.

"Brother Dugu, don't speak, if you provoke the clouds, the power of the thunder will increase!" Lu Yuanfeng was a little anxious, these were also from his father, he had not experienced it, and at this time, seeing Dugu Yu yelling at the thunder, he couldn't help but be scared out of a cold sweat.

Dugu Yu was so frightened that he quickly shut up, this second blow had already made him suffer a lot, if the power increased again, I don't know if he would be able to deal with it safely.

"Boom"

The third thunderstorm finally fell, and Dugu Yu hurriedly spread his luck all over his body, and quickly slashed the iron sword in his hand towards the thunderstorm.

"Ahh

After a scream, the clouds slowly dissipated, and the sky returned to its original state. Only those who have seen this with their own eyes know what has just happened.

"Brother Dugu!" Lu Yuanfeng was the first to wake up from the shock and hurriedly ran to the ruins.

"Hurry up and save people!" Tong Yan also reacted, and hurriedly beckoned people to sort out the ruins.

"I, I'm here!" At this time, Dugu Yu's weak voice came from the ruins, and everyone breathed a sigh of relief, but the speed in their hands still did not decrease.

At this time, one after another aura continued to converge towards Dugu Yu, and in an instant, a vortex of aura larger than just now was formed.

"This is the benefit of the catastrophe, it is really envious and terrifying. Tong Yan looked at the aura vortex and muttered.

Speaking of Duguyu, at this time, the aura entered the body one after another, constantly repairing the body tissues that had just been destroyed.

He struggled to get up, endured the severe pain all over his body, sat cross-legged, and slowly guided the aura in his body to begin to heal.

"It's not without benefit to be struck by lightning, at least this body is more than twice as strong as before!" Dugu Yu felt the increase in the strength of his physical body, and thought of it with some relief.

After a while, the aura vortex dissipated, and Dugu Yu's injuries also recovered fifty percent, and at this moment, the realm was stable at the peak of the first order of qi refining, and it might not be long before he could break through again.

"Brother Dugu, how do you feel?" Lu Yuanfeng took the lead in front of Dugu Yu and asked.

"It's not good, I was almost killed by lightning!" Dugu Yu said a little angrily.

"Haha, and still have the heart to joke, well, it shouldn't be a big deal. When Lu Yuanfeng heard this, he laughed and stepped forward to help Duguyu up.

Coming to everyone, Duguyu said a little embarrassed: "Sister Tong Yan, I'm really embarrassed, this dormitory is gone, I don't know if this will be the case......"

"It's okay, it's just a dormitory, it's nothing. At this time, Tong Yan looked at Duguyu as if she was looking at a treasure, and the more she looked at it, the more happy she became.

Being a little hairy by Tong Yan, Dugu Yu hurriedly said: "Sister Tong Yan, you don't want me to return your bedroom with my body, this is not good, I am still young, I should spend my time on cultivation." ”

Seeing that Duguyu wanted to say more, Tong Yan hurriedly interrupted him, "You little brat, what are you talking nonsense!"

After speaking, he secretly glanced at Lu Yuanfeng, lowered his head and did not speak again.

"It's okay if you don't have it, then you are not allowed to detain my spirit stone, it is my entanglement with Brother Lu!" Dugu Yu seemed to think of something, and hurriedly said out loud.

"Don't worry, naturally I won't detain your spirit stone. By the way, you have this. Tong Yan glanced at Dugu Yu, and then handed a token-like thing to Dugu Yu.

"What is this?" Duguyu asked, looking left and right, looking up.

"This is the token of the Elder Keqing of the Wantong Chamber of Commerce, with this token, you can withdraw 100,000 lower grade spirit stones in any branch of the Wantong Chamber of Commerce, and there are 10,000 lower grade spirit stones to take every year. When Dugu Yu heard this, he hesitated.

"You don't have to refuse in a hurry, I know that the little Wantong Chamber of Commerce will definitely not be able to keep you, but we are also willing to form a good relationship with you, besides, there are countless places where you need to use spirit stones on the way to cultivate, if you don't have a strong financial supply, I'm afraid that the cultivation speed will slow down a lot." After Tong Yan finished speaking, Dugu Yu thought about it, thinking that he almost capsized because of fifty taels of silver, but now he wanted to take the spirit stone in his hand.

"Sister Tong Yan, don't you know what obligations this Elder Keqing needs to fulfill?" Dugu Yu knew that there was no pie falling from the sky, and since Tong Yan had offered such a generous treatment, he would definitely have to do things for him.

"This shouldn't be difficult for Brother Dugu, you only need to refine the elixir for my Wantong Chamber of Commerce once a year. Tong Yan looked at Dugu Yu and said with a smile.

"That's all?" Dugu Yu obviously didn't believe it.

"That's all, of course, if you become strong one day, please help me when my Wantong Chamber of Commerce is in danger, but that's all for later, you have just refined the Qi Realm now, and it's too early to say this. Tong Yan has basically determined that Duguyu will agree.

"Well, I agreed. Dugu Yu breathed a sigh of relief and nodded and agreed to Tong Yan's request.

"Next, let's drip blood to recognize the master, the token will record your identity breath, even if the token is picked up by others, it will not be used. ”

Tong Yan told Duguyu some things about the Chamber of Commerce, and arranged for someone to take Duguyu to rest.

"Huh, this catastrophe is really terrifying!" Dugu Yu muttered to himself with palpitations.

"Now that we've arrived at the Qi Refining Realm, let's see what changes have been made in the Sword Codex. Dugu Yu couldn't wait to open the package, and his fingers just touched the "Sword Codex", only to see that it turned into a streamer and instantly disappeared into Dugu Yu's eyebrows.

"Have you entered the sea of knowledge? Sure enough, it's the same as Grandpa Li said. Immediately, Duguyu's consciousness sank into the sea of knowledge, and he saw a different "Sword Classic" imprinted here.

"The Sword Book is a little different. Duguyu found that the "Sword Codex" at this time had turned golden, and the word "Sword Codex" on the cover was also slightly different.

"The Sword Dictionary" is left by the ancestors of the Dugu family, the specific origin is unknown, it is all-encompassing, there are many types, the children of the Dugu family can practice, and they can also record their own combat skills, body refining exercises, etc. in the Sword Dictionary, remember, the non-anti-heaven moves "Sword Classic" will not be included. ”

The opening sentence expounds the anti-heaven aspects of the "Sword Codex".

"Since this is the case, then choose a set of body refining exercises and a set of sword skills, so that you can also have a few more chances of winning in the admission assessment in ten days. ”

Dugu Yu searched for a long time and finally found a classic that suited him. A body refining technique "Sword Body", a sword technique "Mixed Yuan Sword Technique", the two complement each other.

The cultivation of the sword body is to condense its own true qi into sword qi, run it according to the week, temper the meridian body, and at the same time release the sword qi to increase the power of the sword body, which can be said to be both offensive and defensive, but this sword qi does not seem to be easy to condense.

Let's take a look at "Mixed Yuan Sword Technique" again. After a period of research, Dugu Yu finally understood the horror of "Mixed Yuan Sword Technique".

"Mixed Yuan Sword Technique" has a total of three styles, the first style of drawing the sword, which can increase the speed of the sword body in an instant, and the second type of swinging sword, this style of sword is mighty, such as rushing rivers, once the sword is formed, it is stronger than a sword. The third type of sword separation, although this style is called leaving the sword, it is not thrown, but the harmony between man and sword, to achieve the unity of human sword, and to "turn into" itself into a sword and fight with the enemy.

"Sure enough, it is the combat skills included in the "Sword Classic", which is extraordinary. Dugu Yu sighed, and was about to cultivate, when suddenly there was a strange movement in the dantian.

"Huh?" Dugu Yu hurriedly looked inward at the dantian and found that his true qi was absorbed by a crystal stone.

"Oops, what is this?!" Dugu Yu suddenly thought that a transparent stone had hit him when he was in the Demon Beast Forest, but after that, there was no abnormality in the body, and at this time, the true qi was generated in the body, and the stone came out to make a mistake.

I saw that after the last trace of true qi was also absorbed by the transparent stone, the stone didn't seem to be satisfied, and began to absorb Duguyu's blood and qi.

"It's over, it's over, it's really over this time. Duguyu was completely desperate at this time.
