A few days later, Si Chengcai was able to recover, thinking about the scene a few days ago, he still has lingering palpitations, that big battle, if it weren't for the four great heavenly venerables and the evil slaying heavenly demons to die together, there would be no current cultivation realm.

Tianfeng, Mingqiong, Zixi, Huaquan, these four names have been kept in Si Cheng's heart forever from this moment.

"That day Feng actually comprehended the way of heaven, it seems that this person may be like a certain ancestor of today's family!"

Si Cheng sighed, and that Tianfeng not only comprehended the way of heaven, but also could control it, and that sword was the best embodiment.

Si Cheng shook his head with a wry smile, he hadn't even comprehended half of it until now, let alone any control, it might have been a long time ago.

However, Si Cheng will not give up, whether it is to make himself stronger, or to make Xiaoyan wake up, these are all things he must do.

As for Na Mingqiong, it seems that he should have comprehended the way of the clouds, but I don't know what he has to do with the Yun family, but the Yun family has almost disappeared in the long river of history now.

The last two themselves can't see the clues, and they don't know if anyone in those hidden families is their descendants.

Slowly extruding a breath of turbidity, Si Cheng looked down at the long sword in his hand, according to the picture, this sword was used by Tianfeng, which shows that this sword must be extraordinary.

"I don't know what level it is!" Si Cheng bowed his head and said to himself, it stands to reason that there will be no immortal weapons in the cultivation world, but the venerable weapons are much weaker than the immortal weapons.

Especially seeing that battle, Si Cheng felt that this should not be a venerable weapon, because it was much stronger than a venerable weapon, otherwise it would not be possible to finally kill the evil.

"Be careful, you know what level of sword this is!"

After a long time, the voice of the heart of space sounded in his head, "You try it by dropping a drop of essence blood!"

Si Cheng nodded, then broke his finger and forcefully forced out a drop of bright red essence blood, and then landed on the long sword with a click.

"Whew!"

The moment the essence blood touched the sword body, it directly dissolved, and fused towards the sword body, but the long sword did not move at all.

"Sure enough, Si Cheng, one drop is not enough, continue to merge into the essence blood!" The excited voice of the Heart of Space came from his mind again.

Hearing this, Si Cheng was also stunned, but he still raised his finger and forced out a drop of essence blood again, followed by two drops, three drops.

Until the tenth drop, the surface of the long sword suddenly scattered a ray of brilliance, which was very dazzling, seeing this scene, Si Cheng couldn't help but be overjoyed, because this brilliance he had seen before, it was in the picture of the ancient battle.

It's just that the current one is much bleaker than the one in the picture, and it can't even be compared, but for Si Cheng, this is a kind of harvest, a joy from the heart.

Eleven drops, twelve drops, and soon twenty drops, but the sword no longer seemed to move, and the brilliance only stayed at the previous moment, no longer increasing.

"The appetite is too big, if it goes on like this, I can't stand it!" Si Cheng smiled bitterly in his heart, essence blood is different from ordinary blood, it is the root and source of blood in the body, and there is not as much blood as there is.

Twenty drops down, Si Cheng felt dizzy, if thirty drops or even forty drops, it would be strange if he didn't faint.

However, the matter has come to this point, Si Cheng is unwilling to give up, and then gritted his teeth, and the essence blood was forced out again, and after a while, it reached nearly thirty.

"No, if I don't react, I'm going to finish playing!" At this moment, Si Cheng had the intention of giving up immediately.

But for some reason, Si Cheng didn't do this, and drops of essence blood were still slowly flowing out of his fingers.

"Tick! Tick!"

Thirty drops, thirty-one drops, thirty drops, thirty-three drops!

"Boom!"

When the thirty-third drop of essence blood merged into the sword body, the long sword shook violently, and a crisp sound was transmitted from the sword body, not only that, but an extremely powerful energy fluctuation was directly emitted.

"Who is disturbing the slumber of this sword spirit!"

An old-fashioned voice came from within the sword body, and then filled every corner of the space.

"Sword Spirit?"

"Hahaha!Si Cheng, I guessed correctly, this is the sword spirit!"

"Isn't the sword spirit different from the machine spirit?" Si Cheng rolled his eyes speechlessly, is it necessary for this spatial heart to be so excited?

"Haha! You're lonely, the machine spirit is the machine spirit, and it can't be compared to the sword spirit at all!"

"How?" asked Si Cheng with some curiosity.

"Well, let's put it this way! The machine spirit is a high-level magic weapon born of the spirit, note that it is only spirituality, but the sword spirit is different, it is an independent spirit, itself is also extremely powerful, to play the most straightforward analogy, if there is a sword spirit in the long sword of a venerable weapon, then its power can be close to the artifact, and it is not an ordinary artifact, it is not limited by the level of the magic weapon itself. ”

"Hiss!" Si Cheng took a breath directly, if so, then the so-called sword spirit is too exaggerated!

"Don't think it's incredible, that's the case, now you have to communicate well with that sword spirit and try to make it work for you, otherwise it will be a pity, especially those essence blood of yours!"

Si Cheng smiled bitterly, those thirty-three drops of essence blood almost made him faint directly, if it weren't for the sudden change in the long sword, maybe he would really faint.

"Hello Sword Spirit! I'm Si Cheng! I'll wake you up with my blood!" Returning to reality, Si Cheng looked at the long sword that was still shaking, and said tentatively.

"You, such a weak human being, you can leave, I won't use it for you!" seemed to know Si Cheng's thoughts, and the sword spirit said mercilessly.

Si Cheng smiled bitterly, indeed, the strength of his Saint Venerable Middle Realm could not be compared to Tianfeng at all.

"Sword Spirit, I know that you used to follow Tianfeng senior, and he was very powerful, but didn't my Si Cheng have a day when he was as strong as him......?"

"Wait!How do you know this, especially Tianfeng!" Before Si Cheng's words fell, the sword spirit said directly in surprise.

"This ...... To be honest, when I touched this sword with my hand, that picture appeared in my mind, which was the picture of Tianfeng, Mingqiong, and their four predecessors working together to kill the evil and destroy the Heavenly Demon. ”

"So that's the case, but even so, I won't promise you, this sword spirit is a loyal sword spirit, even if the master is no longer there, I will always accompany him!"

At this moment, the sword spirit's voice was a little low, and his voice seemed to tremble faintly, which seemed to remind it of Tianfeng, the master who had long since passed away.

"If that's the case, then I can only say that you are not called loyalty, but foolishness!"

"What? A small Saint Venerable Realm dares to slander this sword spirit like this, believe it or not, I slashed you with one sword!"

At this moment, the sword spirit was furious, and the entire sword body began to shake violently, and it seemed that the next moment, Si Cheng would be cut in half.
