The next day, in the early hours of the morning.

Chen Yutian, as usual, sat cross-legged on the bed, the spiritual platform was empty, waiting for the morning sun to rise, the appearance of that touch of purple gas.

Martial arts internal force training to the point where he has no effect on hard training, except for the occasional epiphany has been assisted by natural treasures, the most effective method of internal force refinement is to absorb the purple qi that accompanies the rising sun. This purple qi is born with the rising sun, which is of great benefit to those who practice martial arts.

Especially after the power reaches the separation of the body, the effect is even more significant.

Therefore, those who practice martial arts generally do not let go of the purple qi given by God.

The same is true of Tatsu Yutian.

As the time slowly approached, outside the window, a touch of golden light slowly appeared from the horizon in the east, and then, a round of red sun, slowly climbed up, appeared in the eyes of the world.

And in the place where the world is invisible to the naked eye, I can only see a touch of rich and incomparable purple qi spreading between heaven and earth with the vitality of the rising sun.

Majestic. Shocking!

The Chenyu Heavenly Spirit Platform was empty, but the spiritual sense was extremely sensitive, and with the subtle and rich purple qi flowing down the nose into the body, an indescribable pleasure suddenly appeared in my heart.

At the same time, the Nine Tribulation Cloud Dragon in his Dao body also emitted a cheerful humming sound as the purple qi entered his body.

One after another, the pure and incomparable sword qi suddenly emerged with the humming of the Nine Tribulation Cloud Dragon, which was completely different from the internal force that operated in the dantian.

Feeling such a change, Chen Yutian is not happy.

"Flick your fingers into sword qi...... Ever since the internal power of the Dragon War mutated, I have finally reached the realm that all swordsmen admire......"

When the words fell, Chen Yutian's eyes suddenly opened, and the two essences suddenly crossed like sharp swords!

Chen Yutian pointed his fingers together into a sword, and a wisp of sharp aura surrounded his fingertips, faintly exuding a fierce sword intent.

This is the sword qi that Chen Yutian condensed by himself by performing his sword technique.

This is the realm of the unity of human and sword in the legend of martial arts swordsman.

The so-called unity of man and sword means that man and sword are not separated from each other, man is the sword, and the sword is man.

After reaching this level, even if the swordsman does not use the sword, he can perform advanced swordsmanship and show the mastery of swordsmanship, because they themselves are swords.

Even everything in the world can be used as a sword in their hands.

This is the profundity of the unity of man and sword.

It is also the kendo realm that countless swordsmen in the martial arts dream of.

Now, after the internal force mutation caused by the innate dragon vein, Chen Yutian's sword path has finally climbed to this realm.

"Flick your fingers into a sword, no sword is also a sword, this realm of human sword unity, it is really subtle......" Looking at the purple gold sword qi circulating between his fingers, Chen Yutian's eyes showed a satisfied smile.

But suddenly, his expression suddenly froze on his face.

Because, he thought of one thing.

This is related to the silver needle found on the corpse yesterday.

When the silver needle was found, everyone thought it was a poisonous needle, but later it was found that there was no poison on the needle, and there were no traces of poisoning on the deceased.

So what exactly was the role of the silver needle, which stumped everyone present at the time.

Tatsuyutian is no exception.

But his own unintentional words made him have a new idea about this issue.

"Is it ......?"

Chen Yutian looked at the sword qi flowing between his fingers, and his eyes lit up slightly!

Could it be that the silver needle is the carrier of the heart-destroying sword qi?

Such a thought suddenly flashed through his mind.

This idea is extremely bold, not only bold, but also extremely unbelievable, after all, in people's cognition, sword qi should be emitted by a sword.

But at the moment, Chen Yutian's idea is to break this limitation.

The sword qi carried by the silver needle...... If such an idea is known to others, they will definitely think that he is a madman.

But Chen Yutian knows very well that this possibility is not impossible.

Since the swordsman who combines the human sword can use all things in the world as a sword to fight, it is not impossible for the silver needle to use as a sword to emit sword qi.

But such an idea must have a big premise, that is, the realm of the murderer has reached the realm of the unity of man and sword.

But this is clearly unlikely.

After all, the realm of the unity of man and sword is extremely difficult to enter, and if it weren't for that, it wouldn't have become the realm of the sword path that all martial arts swordsmen dream of aspiring to achieve.

Yue Lingxiao should not be able to step into the realm of Rusi.

But Chen Yutian thought of another possibility.

"If things are really the way I thought...... Chen Yutian couldn't sit still anymore, he got up directly from the bed, pushed open the door and went straight to the private courtyard where Master Long Zun lived.

At this time, the sky was already bright, and everyone in Jiulong Mansion had already gotten up, and they were all slightly stunned when they saw Chen Yutian hurriedly running to the backyard.

But Chen Yutian obviously didn't pay attention to this.

He went all the way to Long Zun's single courtyard and saw Long Zun sitting with the Ice King, Yan Zun, and Sword Saint drinking tea.

Seeing him coming in a hurry, a flash of curiosity flashed in the eyes of the four saints.

"Yutian, why are you in such a hurry, is something going on?" Long Zun looked at his apprentice and asked curiously.

Chen Yutian shook his head slightly, and then looked at the four saints in front of him.

"Nothing happened, the disciple just thought of a question and came to ask the master and the three seniors for advice. ”

Long Zun and the Three Sages glanced at each other, looked at Chen Yutian, and couldn't help but ask curiously, "Oh, what's the problem?"

"I want to know, is that heart-destroying sword qi a sword technique, or an internal force heart method?" Chen Yutian said the question in his heart.

After hearing this, the four saints' expressions suddenly moved, and after glancing at each other, Long Zun asked, "Why are you asking about this matter?"

Chen Yutian didn't answer directly, but said: "It's not convenient to disclose this matter for the time being, Master, please tell me the truth, that heart-destroying sword qi is an internal force heart method?"

Hearing this, Long Zun was slightly stunned, then smiled bitterly and said, "I really can't hide anything from you!"

Long Zun's words, the moment he said it, Chen Yutian's heart suddenly rippled.

"Is that so?"

"Yes. Long Zun nodded slightly and spoke, "Everyone in the martial arts back then thought that the Evil Sword Old Man's Heart-Destroying Sword Qi was an extremely evil sword technique, but when the Evil Sword Old Man died in the hands of the head of the Taiyi Sect, the head of the Taiyi Sect personally revealed it, and the world knew that the so-called Heart-Destroying Sword Qi was not a sword technique at all, but a very vicious internal force method. ”

Chen Yutian's expression became slightly solemn, looked at Long Zun, and said, "In other words...... The so-called Heart-Destroying Sword Qi should be called Heart-Destroying Internal Force at that time, right?"

Long Zun nodded, "That's right, it's just that the cultivation method of this kind of internal force is too vicious, so when the internal force list was arranged, this kind of internal force was not counted in it, and the cultivation method has been destroyed in front of the head of the Taiyi Sect back then......"

Hearing this, Chen Yutian's eyes flickered slightly involuntarily, interrupting Master's words.

"Wait a minute...... Master, you said that the cultivation of the mind has been destroyed by the head of the Taiyi Sect...... In that case, then ......"

There was a look of disbelief on his face.

Long Zun nodded slightly, his expression slightly solemn.

"This is also the reason why we were shocked after knowing the death of the deceased from the mouth of the cold weather, obviously the cultivation method of the year has been destroyed by the head of the Taiyi Sect in front of the world's heroes, but for some reason, the heart-destroying internal force actually reappeared after a hundred years...... Maybe the old man of the evil sword back then had other arrangements......"

Chen Yutian nodded slightly.

"Perhaps...... But I still thank Master for helping the apprentice solve his doubts...... In addition, the apprentice had other important matters, so he took his leave first. ”

"Okay, there you go......"

Long Zun's voice landed, Chen Yutian made a slight "please" gesture, and left the backyard......

Walking out of the courtyard gate, Chen Yutian touched his chin and groaned secretly as he walked.

"It turned out exactly as I thought...... In this case, the mystery of the silver needle is basically clear, and the next thing to figure out is the strange serpentine mark...... The role of this thing must be clarified, and I have a hunch that this mark should involve many important things......"

Thinking and walking, before I knew it, I had come to the door of Gongsun's autopsy.

Chen Yutian glanced up and smiled slightly bitterly, how did he come here unconsciously......

"But since you're here, you might as well ask how the autopsy went. ”

Thinking about it, Chen Yutian pushed the door and walked in.

Inside, as imagined, six corpses were neatly placed in front of the door, and four human heads were placed on the table beside them.

Gongsun was among the six corpses, carefully examining each one.

He was too serious and too immersed, so much so that he didn't even notice when Chen Yutian pushed the door in.

Chen Yutian didn't intend to alarm him, but just quietly watched him busy among the corpses, and the corners of his mouth slightly provoked a faint arc.

It wasn't until Gongsun had examined all the corpses and breathed a sigh of relief that he found Chen Yutian, who had been standing there for a long time.

"My lord?!" Gongsun was slightly stunned.

Chen Yutian smiled faintly and said, "You don't have to be so polite...... Let's talk about any new discoveries......

Gongsun's eyes dimmed slightly.

Seeing this, Chen Yutian was shocked and asked, "Could it be ...... Didn't find anything?"

Gongsun shook his head slightly and said, "That's not it, I found a lot of old wounds on Ling Zhanwu's body, and I also found a small amount of poisonous reaction in his stomach. ”

"Poison?" Chen Yutian frowned slightly, "The cause of Ling Zhanwu's death doesn't seem to be poisoning, right?"

"Yes, he died from the Heart-Destroying Sword Qi and beheading, and the poison in his body is not highly poisonous, but a dream herb that is often added to medicinal herbs to neutralize medicinal properties...... It's not some deadly poison. Gongsun explained.

Chen Yutian nodded and said, "I see." ”

"It's just that these findings don't help us solve the case in the slightest...... Alas......" the prosecutor sighed slightly.

Chen Yutian smiled faintly and comforted him: "Sir, don't be discouraged, we still have two important clues, as long as the two clues can be clarified, I think the case will be solved as quickly as possible." ”

Gongsun sighed and said, "I hope so." ”

At this moment, Chen Yutian's expression moved, and then he showed a bright smile, and said: "Cao Cao Cao is here, just now I was talking about those two clues, this is a gain......

As he spoke, he took out a jade plaque from his bosom.

It was the one that could control the Xuantian Guard's team.

Gongsun saw that he understood what was going on, and asked, "Xuantianwei has sent news?"

Chen Yutian nodded, "Yes, they have already investigated what that serpentine mark is. ”

"Oh, the student was a little curious. Gongsun said.

Chen Yutian smiled: "Mr. Gongsun is really undisguised...... According to the investigation of the Xuan Tianwei, this mark was a secret mark when the Nine Snakes Society had not yet been disbanded, and it was used to secretly contact the members of the Nine Snakes Society who were walking outside, and in addition, whenever the Nine Snakes Society found a target worthy of their efforts, they would also leave such a mark on the wall of the target, which meant to inform the members of the society that this was a piece of fat and could be eaten. ”

Hearing this, Gongsun smiled slightly and said, "So...... For the people of the Nine Snakes Society, this mark is equivalent to the mark of a treasure...... After all, the fat that can be used is no less than a treasure trove for them robbers!"

"Not bad!" Chen Yutian nodded slightly.

But the next moment, he was stunned.

"yes, how could I not have thought of it......" After a moment, he subconsciously muttered to himself.

Gongsun didn't know why, and asked, "What are you talking about, my lord?"

"Treasure trove...... Treasure...... Where the Treasure Hides...... Gongsun, you are so smart, why didn't I think of it?"

Chen Yutian muttered, repeating these words constantly, making Gongsun even more confused, but he was only at a loss for a moment, and then thought of the key place.

"What do you mean...... The imprint on that painting?"

Chen Yutian nodded emphatically.

"Yes, Mr. Gongsun, if you continue to reason like this, the things in that painting should be self-evident!"

Gongsun was slightly stunned for a moment, and then as if he had thought of something, his expression suddenly changed, and an extremely rich color of disbelief slowly came out of his mouth.

"Unlikely......"

Chen Yutian smiled slightly: "It's impossible, let's see it for ourselves......"

With that, he left the autopsy room and walked to his room......

Gongsun hesitated slightly, and then hurriedly followed......

A moment later, in Chen Yutian's room, two extremely shocked exclamations suddenly came out of it, and the entire Nine Dragons Mansion was shocked by it!

In the room, Chen Yutian and Gongsun looked at the scene in front of them, their eyes full of disbelief.

"This ...... It's really ......," Gongsun said in a trembling voice.

Chen Yutian was surprised, and there was also a look of extreme joy in his eyes.

"I didn't expect it to really ...... here"

In front of them, in the mezzanine of the painting, there was a white paper no more than the size of a palm, and the paper was depicted with strange lines, as if it was broken.

This thing is one of the nine remnants of the map that records the burial place of the Wind Clan's treasure!

It's also the only remnant of the Heaven Cult that hasn't got!
