Not to mention seeing it, it is simply unheard of.

"Boy, don't look at me with this kind of eyes. There are so many things you have never seen before." The big black dog looked at Su Yue with contemptuous eyes.

Su Yue took a deep breath. Although it was a bit unbelievable, facts were better than words. The big black dog in front of him could indeed speak human words and also make very human expressions. This was definitely not a dream.

"Where are you from? Why are you in my room?" Su Yue's adaptability is still very strong. If someone else is gone, he may be shocked and fled.

Of course, Su Yue also saw that this big black dog seemed to have no malicious intentions towards him.

"I was here, boy, I have lived with you for four years."

"But you didn't see me before." The big black dog said with his head held high.

"What?"

"Have you lived here for four years?" Su Yue looked surprised, frowned, and rolled his eyes and said, "Then why can't I see you before?"

"I was unable to come out of the sealed Sky Thunder Sword before, so of course you can't see me." Big Black Dog said for granted.

"Tianth Thunder Sword?" Su Yue was stunned again.

"Well, it's this sword!" The big black dog's mouth moved.

Su Yue's eyes also turned and looked at a long rusty sword lying quietly there.

This sword was bought by Su Yue at the Rose City Trading Market four years ago. I remember it was found on a street stall. At that time, Su Yue felt that the sword was a bit unusual at first sight. In addition, the price was very cheap, so he bought it back. The stall owner of the stall also solemnly told Su Yue that the sword was obtained from an ancient ruin, but Su Yue did not think it was intended, and only said that the stall owner was fooling him.

When the sword was taken back, Su Yue also spent some time studying it carefully, but in the end there was no accidental discovery, and later he threw it aside and never paid attention to it.

Unexpectedly, today I saw this magical scene. A big talking black dog claimed to have walked out of this sword. Moreover, this sword also has an extremely loud name, called the Tianlei Sword.

"Boy, tell you not to look at me with this kind of eyes. Don't look at the Tianlei Sword that is rusty, it is an absolute holy object. However, in the battle a hundred thousand years ago, it was eroded by the blood of the demon god, and it lost its original spirituality and was eventually sealed. Master Dog, I am the sword spirit of the Tianlei Sword. Look at Master Dog, I will know how powerful the Tianlei Sword was back then." The big black dog said with a grin.

Su Yue couldn't help rolling his eyes.

"So, you can't come out of the Heavenly Thunder Sword?" Su Yue's eyes rolled and he said.

"Nonsense, if it could come out of it, Master Dog wouldn't come out early? You'd think it would be very comfortable if you kept it in it for so long?" The big black dog rolled his eyes.

"Then why can you come out again now?" Su Yue asked again.

"Hehe, I have to thank you."

"If the Tianlei Sword had not absorbed your Yuanli for four years, I'm afraid it would have been sealed. Boy, it was because of your Yuanli that the Tianlei Sword could unseal the seal, and I could also freely enter and exit the Tianlei Sword." The big black dog said to thank Su Yue, but that look, there was no sign of thanking.

After hearing this sentence, Su Yue felt that his eyes were dark and he almost fell head-on.

That's right, since four years ago, his strength has been regressing. The Yuanli that has been practicing hard has disappeared without realizing it. It turns out that all this has a reason, and the source of all this is this damn Tianlei Sword.

Thinking of being poked at the back of someone in the academy every day in the past few years, Su Yue was so angry that his teeth were itchy. If it weren't for the damn Tianlei Sword that he had sucked away the Yuanli, how could he have fallen to the threat of a guy at the third level of body tempering?

Seeing Su Yue's face turned pale, the big black dog also showed a three-point embarrassing expression.

"Damn it, you said that the Tianlei Sword has been sealed since 100,000 years ago. So why haven't you sucked other people's energy over the years, but you just wanted to suck my energy?" Su Yue said gritting his teeth.

"Do you think I don't want to absorb other people's energy? But it's useless if others' energy is absorbed. Only your energy is useful if you absorb it. A cultivator who does not match his soul will not be able to untie the seal of the Heavenly Thunder Sword even if he absorbs it." The big black dog shouted with confidence.

"Boy, you actually got a big advantage. It took only four years to untie the seal of the Sky Thunder Sword. Humph, if someone who knows a little about the Sky Thunder Sword, he would probably want him to untie the Sky Thunder Sword in four hundred years or four thousand years. He would be happy." The big black dog shook his long tail and said contemptuously.

"Damn it!" Su Yue wanted to step forward and beat the damn big black dog, but looking at his size and thinking about his current strength, Su Yue still resisted the impulse idea.

"I got a big advantage. The Yuanli I have worked hard to cultivate for so many years has been sucked clean. Is this a big advantage?" Su Yue took a deep breath.

"Boy, what do you know!"

"The Heavenly Thunder Sword is the relics left by my master. In the battle a hundred thousand years ago, the world changed color. Even this world was broken. I don't know how many terrible powerful people died. Once, the master fought for three days and three nights before he finally killed a powerful god and demon. The Heavenly Thunder Sword was also invaded by the blood of the god and demon. Later, the master did not clear the blood of the god and demon on the Heavenly Thunder Sword. On the contrary, he injected his lifelong cultivation experience with his soul power into the Heavenly Thunder Sword, in order to find the inheritor one day."

"Later I realized that the master must have felt that he might not be able to survive that battle, so he would have such an arrangement. He didn't want what he learned in his life to disappear into the vast starry sky." When he said this, the big black dog was a little sad.

There were also tears in those red eyes.

Although the big black dog didn't say much, Su Yue was extremely shocked when he heard it. The battle a hundred thousand years ago also had simple records in ancient Chinese classics. Su Yue had watched such classics. The classics said that even the space barriers in the big world were shattered, and all the lives and creatures in the world were killed and injured.

After the war, the world recovered for 30,000 years.

For Su Yue, the war was too far away and was simply a legend. On the continent today, many people doubt whether the war really existed and whether it was fabricated by some people.

Unexpectedly, Su Yuejian saw a big black dog who had personally experienced that battle, and was also a sword spirit.

It is conceivable that the owner of the Big Black Dog must also be an extremely terrifying strong man, right? Even gods and demons can kill them. How powerful is this? It’s exciting to think about it.

"Boy, do you think you have gained a big advantage? If the Heavenly Thunder Mind Method left by the master is spread, the whole world will probably fall into chaos. I don't know how many people will fight for it. Now, the Heavenly Thunder Mind Method that countless people have always dreamed of is yours." The big black dog blinked his red eyes and tilted his neck.

"Where was the Thunder Heart Method that day?" Su Yue looked around.

"Are you ready?" the big black dog suddenly asked inexplicably.

"What?" Su Yue asked naturally.

"Buzz!"

At this moment, Su Yue only saw a ball of milky yellow light flying out from the rusty sky thunder sword and then pouring into his head. Then, a buzzing sound appeared in his mind. A large amount of memories and information quickly merged with Su Yue's own memories.

Immediately, a sharp stinging pain made Su Yue let out a low roar.

It is conceivable that such a huge amount of information is obviously not easy to integrate into one's memory in a very short period of time.

Fortunately, this sharp stinging comes and goes quickly. After only a few breaths, the pain gradually eases.

Su Yue opened his eyes again and saw a huge dog head full of sinister smile.

"Oh, it's such a cheap guy. If I could practice the Heavenly Thunder Heart Method, it wouldn't be your turn." Big Black Dog sighed.

"However, since you have accepted the inheritance of your master, you have to be strong quickly and not be killed by someone at will one day, wasting your master's efforts in vain." The big black dog turned his tone and said seriously.

"Do you think I don't want to be stronger quickly? Damn, I had already cultivated to the seventh level of body tempering, and now I have to start from scratch." Su Yue said angrily.

"Hmph, what is the seventh level of body tempering? As long as you practice according to the Heavenly Thunder Heart Method, at most one year or less than half a year, you can reach the ninth level of body tempering." The big black dog yelled and then said proudly.

"You are fooling me, are you?" Su Yue's eyes widened and looked at the big black dog with a puzzled look on his face.

With his qualifications, he had been practicing for nearly ten years. At the age of twelve, he barely broke through to the seventh level of body tempering.

"Boy, you don't know how powerful the Tianlei Xin Method is."

The big black dog grinned at Su Yue again, "By the way, from now on, you can't mention the three words "Sky Thunder Sword" in front of anyone, and you can't reveal any information about the "Sky Thunder Mind Method". Otherwise, you won't know how to die."

"I understand!" Su Yue also pointed at the key point.

If the Heavenly Thunder Heart Method is really as powerful as the Big Black Dog said, with his current strength, he will not be able to protect it at all.

The big black dog nodded with satisfaction, "Master Dog, I'm tired and need a rest. You can watch and practice by yourself."

While speaking, Su Yue only felt a flash of black shadows. In just a moment, the figure of the big black dog in the room disappeared without a trace. I think it must have returned to the Tianlei Sword.

Su Yue, who calmed down, licked his lips, and two rays of light flowed in his eyes.
