The tunnel slowly open up to another underground lake. This lake is very large and the surface shimmer with bright light.
The lake surface is as smooth as the flawless mirror surface. One can see the lake bed in one glance.
Countless crystal formation grow from the lakebed, illuminating the cavern with soft blue, silver and Emarald light.
The cavern ceiling resembles a starry sky due to the millions of glowing crystal cluster on the ceiling.
The water is so clear that the bottom can be seen even at great depth. This underground cavern is approximately 40,000km square.
Large enough to contain islands, underwater caves and hidden cultivation ground, can be consider as underground inland sea.
Inside the water one see large crystal fishes peacefully swimming around. These crystal fishes all have purple rings on their body.
Not only that their organs are visible and they resemble crystals. Normal crystal fish organs and body are translucent.
What these are the not things that catch absolute attention of the three women. But at the bottom of the lake there's something.
A large place submerged under the water. Quietly seating there with the crystal fishes swimming around it.
The place is constructed entirely from translucent crystal that seem to be have never lost it brilliance.
The place glow with a soft blue-white light despite being in deep beneath the lake.
Shi mingxi "just what kind of beauty is this" both agree with her view this magnificent underground cavern is truly beautiful.
Ruo senling "we should go inside the palace. Their must be some treasure inside" at this point shes vibrating from excitement.
Shi mingxi "but this school of crystal fish look dangerous. If we want to reach the underwater palace we have to use old the method we use to came down here"
Shi Yixue "she's right, but I have to wait here. My spiritual energy is still not at it peak" she seat down cross legged.
Not only this place is beautiful. The spiritual energy present in the air ten time more dense and pure then above.
It will be pity not to be used it. Both Shi mingxi and Ruo senling agree to wait for her to recover.
But shi Yixue seem to have forgotten about the fact that she is on verge of breakthrough, seat here in mediative state can result into many times.
Like, the fact that the spiritual energy inside her already had decided that it's time to have breakthrough here.
So, in just ten minutes her body was covered in the white light with golden ruins which suggest the advancement to Golden Core Realm.
And like always it's didn't stop there. It's like water being free from the dam, continuously pouring out.
Her advancement directly reach the late state of Golden Core Realm. If she really seat down another half hour maybe she will even breakthrough to Nascent Soul Realm.
When she open her eyes she saw two women staring at her with narrowed eyes. They didn't ask any questions to her.
Although the spiritual energy here is very dence and pure. Advancing and late stage in just half hour is pure nonsense.
But the problem is that, the nonsense had happened infront of them and they can't just ask about it.
So, everyone just shut there mouth and went down in the water. Both shi mingxi and Ruo senling transformation let them be free.
But Shi Yixue had to be extremely careful with her own barrier. If the school of crystal fishes really sense her presence she's dead.
Unlike the crystal fishes in crystal Lake above were all fishes are on surface. Here they mistle swiming all around the lake.
So, if she want to reach the palace without being catch she had to extremely carefull. Maybe, the advancement had came at the right time.
As the strength of these fishes is definitely higher then her. So, she maintain the barrier to earse all of her presence.
Luckily the barrier prove to be worthy of being 1st grade skill in her inherited book as she manage to reach the palace without being discover by them.
As they came near to the palace they were able to see the structure of the palace more clearly.
The Crystal bridges which connects numerous halls, towers, and pavillions together.
Giant crystal pillars supporting the palace, with each engraved with ancient ruins, glowing softly with golden hue.
A translucent dome like barrier surrounds the whole palace keeping the interior dry and keeping the water away.
When they reach this barrier shi Yixue realize that even though they can see the palace they can't enter it.
The barrier is made of protection formation which is capable of remaining unbroken by even people with strong cultivation.
In another words, it's absolute protection barrier set up ancient people. But, then again space cultivator very much ignore that rule mostly.
Barrier and array formation are more or less useless against them. Formation master mostly hate space cultivator's.
Space rift, unlike the previous attempt this time she was able to connect two point with greater ease and even after closing the rift.
She still have some spare energy left inside her body. She eat few replenishing pill and walk ahead.
Inside the barrier the area is dry and untouched. It's like the time inside the barrier had been paused.
Three of them spread around trying to get general idea about the area. Once, they had finish looking for any danger.
They will regroup and decide to which place to visit first. While, they were discussing about the possibility of treasure inside.
Outside of the place, above the crystal Lake everyone were still busy catching the fishes. The sun is about to set down so everyone are fishing with even more vigor.
Once, the sun set and crystal fishes went back in the water. Everyone stop hunting and went to rest of cultivate.
Inside the royal boat of the Emarald Mist Kingdom, people from the royal family and close friends are chatting with each other.
The Crown prince of the kingdom is looking at the letter sended by his father Aka the current emperor of the kingdom with solemn look on his face.
