But the entrance of the cave is not as wide and vast as Murong Ningyue imagined. In the past, the secret realm that Murong Ningyue entered was a wide one.

However, the scope of this secret realm is pitifully small. It is really as small as a cave. There is nothing in the cave, only a small open space.

Murong Ningyue suddenly felt a little disappointed. This place can also be called the secret realm of cultivation? Did the Sword Sect make a mistake?

Murong Ningyue had the urge to leave the cave and ask Sima Xuan. Just when Murong Ningyue came to the exit of the cave and wanted to leave, she suddenly made an amazing discovery.

The free spiritual power surged between heaven and earth, and Murong Ningyue clearly saw that the flow of spiritual power in the cave was much slower than outside the cave.

Murong Ningyue stopped and fell into deep thought, and immediately understood the key. The biggest use of this secret cultivation realm is the time difference.

According to Murong Ningyue's calculation, after an hour outside, there will be ten hours in this cave, which means that the time in the cave is one tenth of that of the outside world.

This discovery surprised Murong Ningyue, which means that if she practiced in this secret cave for one year, it would be equivalent to practicing in the outside world for ten years. In this way, wouldn’t her cultivation be improved rapidly?

But Murong Ningyue quickly calmed down. Sima Xuan said that he only had one month of cultivation. Besides, the consumption of such a heaven-defying secret realm is definitely very huge. It is probably very rare to be able to use it for one month.

Murong Ningyue’s guess is indeed very reasonable. There are several huge spiritual veins around this cave and formations specially portrayed by masters from the Extreme Immortal Realm.

If the operation of this cave secret realm consumes a lot of spiritual power, Murong Ningyue did not dare to waste any more time, so she immediately sat down and started to practice.

Because of the existence of spiritual veins, the immortal power in the cave secret realm is naturally extremely abundant. Murong Ningyue’s cultivation is unhindered. As long as the time is enough, Murong Ningyue even feels that she can directly cultivate to a ninth-grade immortal!

Time during cultivation always passes quickly, and a month passes in the blink of an eye. When Murong Ningyue was teleported outside the cave, she is still practicing.

I found that the magical power I absorbed was not as much as before. Murong Ningyue then opened her eyes and found that she was already outside the cave.

Murong Ningyue opened her eyes and looked at the cave with a greed. Anyone who has entered such a cultivation treasure land would probably want to go in for a second time after entering.

It’s just a pity that Murong Ningyue no longer had this opportunity. At this time, the entrance of the cave had disappeared. The original entrance of the cave was just a bare stone wall.

Murong Ningyue left in disappointment, but she had already made a secret decision in her heart that she would definitely go to this cave secret realm to practice hard when she had the chance.

Murong Ningyue left the cave secret realm and returned to her room, Yuan Xiaotian came to her door.

"Junior Sister Murong, how does it feel to practice in the secret realm? It should be a big improvement, right?"

Looking at Yuan Xiaotian's smiling face, Murong Ningyue immediately realized that this guy must have known the effects of the secret realm, and he must have been in, so he didn't tell him in advance.
