Liu Chen didn't move, they definitely didn't dare to enter first.

Liu Chen was not polite, and directly entered the Sword King Palace, and those sword qi did not cause harm to him.

After making sure that there was no danger, Liu Chen let the sword spirit in.

The two of them sat cross-legged in the excellent position of the Sword King Palace, feeling the way of the sword.

Although the way of the sword and the way of the sword belong to the same martial arts, they are very different.

After the two of them entered the Sword King Hall for a long time, the others stepped into it one after another, one by one, cautiously and lightly, not daring to disturb Liu Chen's cultivation.

Liu Chen stayed in this Sword King Hall for three days, allowing his Dao Dao to comprehend the realm of mastery, which was definitely an unexpected joy.

Liu Chen has now comprehended the way of the sword, the way of the sword, the way of water, the way of space, the way of the mind, the way of formation, the way of hurricanes, the way of thunder and lightning, the way of ice, and the way of flames.

Those who can perceive the ten realms, and comprehend all the ten realms to mastery, look at the entire god realm and the demon realm, and there is no other.

And Liu Chen is not only that, he has now completed the path of the soul, the way of the sword, the way of ice, the way of fire, the way of space, and the way of thunder and lightning have all approached the mastery.

This is extremely terrifying, if you can comprehend the five paths, then you can directly become a powerhouse in the Great Emperor Realm.

The martial artists of the Emperor Realm are divided into Half Emperor, Quasi-Emperor and Great Emperor.

If you comprehend the three paths, you will be able to become a half-emperor strongman, if you comprehend the four paths, you will be able to become a quasi-emperor powerhouse, and those who will comprehend the five paths will be a great emperor strong.

The Great Emperor powerhouses now do not have either the God Realm or the Demon Realm, maybe they once were, but they have disappeared for some reason, maybe they have been eradicated by the Heavenly Dao, or maybe they are for other reasons.

It can be said that the powerhouse of the Great Emperor Realm is the strongest in this world.

Liu Chen was very excited in his heart, and after he stopped feeling, he looked for the key in the Sword King Palace, according to his previous experience, there must be a key to the next palace here.

However, this time there was an accident, Liu Chen searched for a long time, but he never found the key, the Sword King Hall is only so big, and Liu Chen has already searched all the places he can find.

Even later followed the sword spirit to find it, but it was unsuccessful.

Liu Chen was a little surprised, where would the key be if it wasn't here?

He had already searched the Holy King's Palace, the seven passages, and in addition to the Sword King Palace, the other six palaces had also been searched.

The key can't be in the Sword King Palace, right?

Liu Chen mobilized the crowd to find it together, Liu Chen's appeal is extremely strong, the Soul Slayer King has spoken, who dares not to obey?

More and more people started a carpet search, along with the passages and other palaces.

But he still hasn't found the key to the Sword King Palace.

This made Liu Chen very depressed, he had a strong self-confidence, and he would definitely be able to comprehend the way of the sword in the Sword King Palace.

His current sword path is close to Dacheng, if he can feel it in the Sword King Palace, he will definitely be able to achieve Dacheng.

But the heavens played a joke on him, so that he could not find the key to open the Sword King Palace.

"How can this be?" Liu Chen felt very weird, and searched carefully in the Sword King Palace, urging the ability of the heart eye to the extreme, not letting go of any subtlety.

After a lot of effort, I still couldn't find the key, as if it didn't exist.

The sword spirit was also very depressed, and looked at Liu Chen helplessly.

Liu Chen entered the first passage again and came to the gate of the Sword King Palace, could it be that the key is near here?

Liu Chen opened his eyes again and searched, but the result still disappointed him.

"Boy, I'll take a look outside. The sword spirit patted Liu Chen's shoulder, intending to look outside the Holy King's Palace.

Liu Chen nodded, left the passage, and came to the Holy King's Hall, thinking about whether there was anything he had overlooked.

It didn't take long for the sword spirit to return, shaking his head regretfully, "I can't find it." ”

As a result, Liu Chen had already guessed that the key should not be placed outside the Holy King's Palace.

But the palace inside, every inch has been rummaged, and there is no shadow of the key.

"Could there be other keys that can open two doors at the same time?" Liu Chen guessed.

As soon as the idea came to him, he immediately planned to try it, immediately enter the passage, and remove the other keys.

Sword Spirit also hurriedly helped.

Liu Chen came to the Sword King Hall and took down the yellow six-pointed star from the yellow gate, and the gate was not closed, which made him feel a little incredible.

Then, he entered the other palaces in turn, and together with the sword spirit, he obtained the six six-pointed star keys.

Then, the two of them came to the door of the Sword King Hall again, intending to try them one by one to see if there was a key that could open two doors at the same time.

Liu Chen actually didn't have much hope in his heart, because at the beginning, he tried to use the purple six-pointed star to open the door of the Sword King Palace, but failed.

But Liu Chen still planned to give it a try, and tried the six-pointed stars in his hand one by one.

The result was not at all beyond his expectations, and there was no movement at the gate of the Sword King Palace.

Looking at the six six-pointed stars in his hands, Liu Chen was extremely depressed in his heart, seeing that he had the hope of making the sword path a success, but he didn't expect to usher in such a big obstacle.

If they can't find the key, they can't open the door of the Sword King's Palace, and no matter what method they use, it won't help.

"Huh?"

Liu Chen, who was already planning to give up, suddenly found that the six-pointed star in his hand had changed a little.

They seem to be merging!

This discovery shocked Liu Chen, and he hurriedly put the six six-pointed stars together, and then quietly watched the changes.

To his shock, the six six-pointed stars were slowly moving, slowly merging with each other, a very slow process, but they were real.

"I know! This is the last key!" Liu Chen was overjoyed.

The sword spirit also saw this scene, and his heart couldn't help but be excited.

Some of the martial artists around also looked at each other with excited expressions.

An hour later, the six six-pointed stars fused together to form a huge irregular shape, which was also colorful in color.

But slowly, the huge shape began to shrink, and the color also changed slightly, slowly approaching the red.

Two hours later, the irregular shape had turned completely red.

Seeing this color, it proved Liu Chen's guess even more, because the gate of the Sword King Hall in front of him was red!

Next, everyone watched intently at the change of shape, and slowly began to highlight the six corners, slowly shrinking.

Three hours later, a red, six-pointed star appeared, the same size as the previous keys.

Liu Chen picked it up excitedly, looking at the transparent and warm six-pointed star in his hand, Liu Chen couldn't help but have a touch of joy on his face.

Flying forward, he placed the six-pointed star in the mark on the red gate.

Buzz!

The door of the Sword King Hall really began to tremble, and then slowly opened under the excited eyes of the crowd.
