The three of them were suddenly surprised by Zhao Chen's voice, but they quickly reflected it.

"Sect Master, haven't you come back?" Rong Cheng said as he looked around, as if he was looking for Zhao Chen's figure.

"Don't panic, this is the unique spiritual skill of my Imperial Spirit Sect, sound transmission!" Zhao Chen said lightly in the office. What kind of unique magic skill is this, which is the voice function of the system.

"Sect Master, did you make this sword washing pool! it's just amazing!" Lin Chen had a look of adoration on his face.

The three of them were also surprised and delighted, looking at the building in front of them and curious.

Zhao Chen smiled slightly: "This sword washing pool is used to comprehend the sword intent, and this sword intent is also divided into many kinds, and the sword intent that everyone comprehends is different." This sword washing pool can allow you to enter a state of epiphany, so that you can comprehend the sword intent faster. ”

"Of course, as for what kind of sword intent you comprehend, you have to look at yourself!"

When the three of them heard Zhao Chen speak, they were dumbfounded, and their jaws were about to fall to the ground.

"Sect Master, is it really fake? There is still such an anti-heaven building in this world?" Lei Zhen couldn't help but ask. You must know how difficult it is to comprehend the sword intent, it is simply as difficult as climbing to the sky, and even some people who have specialized in sword intent all their lives have not even touched the shadow of the sword intent.

"It's not fake, it's not fake! You can enter it yourself and try it out!" Zhao Chen didn't explain too much, after all, no matter how much he said, it was better to experience it himself. It's more convincing that way.

"Rong Cheng, as a senior brother, you go in first to make a start. Zhao Chen spoke.

"Yes, Sect Master!" Rong Cheng nodded, his heart full of curiosity and impatience.

Rong Cheng walked towards the only entrance of the Sword Washing Pool, although the Sword Washing Pool was shrouded in a mysterious light curtain, but this light curtain did not block Rong Cheng's step, but Rong Cheng walked through it very easily.

Soon Rong Cheng came to the giant sword in the center and sat down cross-legged very instinctively.

After Rong Cheng sat down cross-legged, he quickly entered the state, and Lei Zhen and Lin Chen clearly saw that the surrounding aura was quickly rushing towards Rong Cheng. Rong Cheng has entered the state of enlightenment.

"It's so easy to do?" Lei Zhen's eyes were originally small, but now they are also wide.

"Is this a state similar to enlightenment? it feels so relaxed!" Lin Chen was surprised and delighted. With such an anti-heaven building, why worry about not being able to become stronger.

Time passes slowly.

Half an hour passed, and the black giant sword in the center emitted a black light, and then the black light turned into a black streamer, entering Rong Cheng's body and merging into Rong Cheng's mind.

Immediately afterwards, Rong Cheng got up and stood up, held a long sword in his hand, and began to dance the sword, the sword light was bursting, and the sword moves and their subtleties were subtle.

"What a powerful killing intent! You can feel it from such a distance!" Lin Chen felt a killing intent from Rong Cheng's body, and he unconsciously felt a chill.

"Kill!" Lei Zhen said two words slightly. Killing sword intent can be said to be extremely powerful sword intent, the sword in the hand, the mind in the heart, everything can be killed, to kill to stop killing, to kill the Tao.

However, although the killing sword intent is very domineering, it is also recognized as the most difficult sword intent to improve, and there is no one. The improvement of killing sword intent is the word "kill". Only by killing can the sword intent be enhanced, and the person who has the killing sword intent will not have a river of blood on his hand.

Lei Zhen looked at Rong Cheng, if Rong Cheng fell into the Demon Dao, the horror of this continent would be another bloody rain. If the killing sword intent reaches the consummation realm, once the sword intent is unfolded, ordinary cultivators will immediately have a chill in their hearts and bones, and they will not have the power to resist at all.

As the so-called killing, all it takes is one look.

Finally, Rong Cheng stopped, he felt his own changes, and his face showed great surprise, very excited and happy.

Obviously, Rong Cheng had a lot of gains this time, and then Rong Cheng left the sword washing pool, and he no longer felt the slightest improvement here.

Seeing Rong Cheng come out, Lin Chen hurriedly asked Rong Cheng, how do you feel?

Zhao Chen looked at Rong Cheng and actually comprehended the killing sword intent, this sword intent could easily turn people into emotionless killing robots. It seems that Rongcheng should be well guided.

"That's right, Rong Cheng, the killing sword intent you comprehended, among the many sword intents, can be said to be the most powerful sword intent. I hope you can cultivate this killing sword intent well, the Haoran of the sect will definitely be able to solve the drawbacks of the killing sword intent, you can cultivate with confidence!" Zhao Chen's voice reached everyone's minds again.

"Really, great!" Rong Cheng said excitedly, he had just heard Lei Zhen talk about some things about the Killing Sword Intent, thinking that he was terrifying and couldn't cultivate the Killing Sword Intent.

Lei Zhen was also surprised when he heard it, but he didn't expect that he had not solved the drawbacks of the killing sword intent for thousands of years, but he was solved by this ground-level spiritual skill.

Rong Cheng kowtowed three times into the distance, and said loudly: "Thank you for the cultivation of the sect master! I will definitely cultivate hard and live up to the cultivation of the sect master and the sect!"

"All right, manly man, don't kneel without moving! Get up, tell me how you feel. ”

"Yes!"

Rong Cheng got up and stood up, just as he spoke.

Washing the sword pool, a stone sword around it, trembling slightly, and soon many cracks appeared in the stone sword, and a blood-colored long sword flew out of this stone sword.

The three of them suddenly felt a stormy wave of killing intent. Few of the three of them annotated the snow-blood-colored longsword in mid-air, and after the blood-colored longsword made a crisp sound in mid-air, it quickly rushed towards the three of them.

Seeing this earth-shattering killing intent attacking, Lei Zhen wanted to block it, but found that he couldn't do anything, the speed of this long sword was too fast.

Lei Zhen didn't hear any screams, looked at the two of them again, and found that the blood-colored long sword was actually circling around Rongcheng, just like a child playing in circles around his father.

At this time, Rong Cheng also felt something, so he stretched out his hand, and the blood-colored long sword obediently fell on Rong Cheng's hand. Rong Cheng felt the familiarity coming from the long sword, so he stroked it gently.

"Sect Master, what's going on?" Lei Zhen asked.

"Oh, I forgot to tell you, the stone swords in the sword washing pool are actually real divine weapons! The long sword in Rong Cheng's hand now is called the Sword of Killing, and it must be that Rong Cheng has comprehended the sword intent of killing and has been recognized by the Sword of Killing. Rong Cheng, you now drop a drop of blood on the sword of killing, complete the confession. Zhao Chen also said slowly.

"Yes!"

Rong Cheng quickly dropped a drop of his own blood on the sword of the Killing Sword, and the Killing Sword recognized the master, so it automatically flew out, circled in the air a few times, seemed to be very happy, and then flew into Rong Cheng's body.

"It's amazing!" I saw the image of the killing sword appear on Rong Cheng's arm.
