This feeling is too small, Luo Yu thought about it for a while, and immediately shot towards that place, passing through a valley halfway, almost when he came to the deepest part of the valley, he found that what made his spiritual sense beat in front of him was actually a small lake, the lake was surrounded by towering trees and dense grass, a scene of green shade, and even the green shade blocked the lake tightly, if ordinary immortal cultivators did not deliberately look for it, it was easy to ignore it.

And the reason why Luo Yu was suspicious just now was mainly because Luo Yu felt that the aura here was a little abnormal, but what was wrong, Luo Yu couldn't say.

Seeing that there was something strange here, Luo Yu would definitely not let it go, and his whole body descended in a flash.

"Hmm!" Luo Yu stepped on the magic weapon in the air, and gradually approached the surface of the lake, but suddenly his body stopped in place, and after a light sigh, his face suddenly changed, and he flew away without saying a word, but it didn't fly out very high, Luo Yu immediately lowered again, and his face turned into surprise!

Immediately afterwards, Luo Yu repeated this strange action continuously, and after a while, the whole person was stunned in place, thinking motionlessly.

"Great! This place is the place where the water attribute spiritual power is the strongest, but it is blocked in this lake by the even more intense fire attribute spiritual power, so this lake is the real feng shui treasure land where water and fire meet. Luo Yu patted his head and said to himself with an exaggerated expression.

The reason why he flew up and down just now was to verify what he was thinking, and as a result, after several tests, he really found that the closer he was to the water surface of the lake, or closer to the edge of the lake, the purity of the aura would be greatly improved, but in a large area, there was only a little bit of particularly pure aura, which was not suitable for long-term cultivation, but it could play a great role in breaking through.

This is what Luo Yu is really looking for!

Since this is the case, Luo Yu couldn't wait to start acting immediately, and after walking around the lake, Luo Yu chose a place not too far from the edge of the lake to open up a cave, where there is a canyon-like mountain crevice, the concealment is not bad, and it is relatively close to the lake, which is convenient for cultivation.

After that, Luo Yu stood in the place where he was going to open up the cave and thought about it slightly, and then thought about how much area he needed, what shape of the cave he needed, and even the space allocation inside.

The best and fastest magic weapon to open up the cave is undoubtedly the Seven Star Yin Fire Blade, this set of evil weapons has followed Luo Yu for the longest time, of course, except for the Biling Han Halberd that has been given away, so using this magic weapon, Luo Yu can be said to be handy, and the subtleties of digging the cave can be dealt with.

After Luo Yu released the Seven Star Yin Fire Blade Magic Weapon, he immediately began to chop those boulders, with the sharpness of the best magic weapon, coupled with Luo Yu's control, slashing on these mountain stones was like cutting tofu, blowing hair and breaking hair, 'crackling' roar kept going, and it was running at high speed and constantly advancing.

Gradually, a cave mansion that was inseparable from Luo Yu's mind began to take shape.

An hour later, Luo Yu stood in an empty stone room, with a look of satisfaction on his face, reached out and touched the surrounding stone walls, and then began to continue to direct the Seven Star Yin Fire Blade to make detailed adjustments.

When Luo Yu finished working on this stone room, he carved a few big characters on it, 'Foundation Building Room', which means a place of cultivation, and the name 'Building the Foundation' was purely for the sake of good luck.

Half a time later, Luo Yu's body appeared in another larger stone room, and there was still a 'click' chopping sound in the stone room, but this stone room was a little different from just now, and a large water tank with a radius of about a foot was dug out of the ground, after Luo Yu built this stone room, he flew outside and filled a lot of water from the lake with a bitter gourd, and then poured the clean water into the tank, and when he saw that the sink was about to be filled, Luo Yu stopped.

Then Luo Yu took out a few low-level spirit stones and held them in his hand, clenched his fists without hesitation, and the red light flashed on his palms, these spirit stones were crushed by Luo Yusheng, turned into some powder and fell into the sink, when he saw that the bottom of the sink was all covered with a layer of shiny white particles, Luo Yu slapped the storage bag again, and took out two small cyan eggs wrapped in green algae from it.

This little cyan egg in the hand also exudes a warm breath, it seems that the mantis turtle cub inside is still alive, seeing this, Luo Yu can't help but put his mind at ease, this is a famous ancient strange insect, if it can be hatched out, and carefully cultivated, it will definitely become a big help for Luo Yu in the future.

Luo Yu slowly put the two small cyan eggs into the sink, this is a cultivation method that Luo Yu found from the "Beast Spirit Spectrum", forcibly using the spirit liquid to hatch it, but this process may be a bit long, but Luo Yu is not very anxious, because even if it is hatched, it is only a young beast at the beginning, and it does not have much ability, and cultivating a spirit beast is a very long-term and patient thing.

When Luo Yu finished dealing with everything in this stone room and carved the three big characters 'Spirit Beast Room' on the door of the stone room, a trace of exhaustion appeared on his face, but he just exhaled lightly and began to build the next stone room.

Among them, when building the 'elixir room', Luo Yu was the most careful, in addition to ventilation, the top of the stone room was polished smooth and neat by Luo Yu, without a little debris, and similarly, since Luo Yu was going to cultivate the elixir, he couldn't get a lot of dirt dug up outside and scattered it in the elixir room.

Because it was the first time to cultivate the elixir by himself, Luo Yu learned from the chores of the medicine garden he had done before, and knew that the first time he cultivated the elixir, he had to be very careful, and he had to be willing to pay the capital, Luo Yu took out dozens of spirit stones, all of them were crushed, and then scattered into the soil, so that the elixir could have a better growth environment.

This method will have a little effect, after all, it increases the concentration of the spiritual energy of the soil, but it is too extravagant, and ordinary immortal cultivators can't afford it, and Luo Yu is also the first time that this will be like this, and after the cultivated elixir adapts to the environment in the cave, this method will naturally not be used again.

The remaining 'Treasure Room' and 'Alchemy Room' didn't need to spend too much thought, and it was so grand that Luo Yu almost only spent half a pillar of incense time to open them up.

And at this moment, Luo Yu really realized that opening up a cave mansion is really not something that immortal cultivators in the Qi cultivation period do, there are too many things in it, of course, this means that if it is built well, if it is swallowed, it will be very fast.

After finishing everything, Luo Yu was indeed exhausted, and he just wanted to go back to the foundation building room and sleep peacefully.

However, the cave mansion has just been built, and there is no means of defense, how can Luo Yu sleep with peace of mind, so he had to drag his tired body to the outside of the cave mansion, take out the array flags of the Hundred Wood Fire Bathing Array and the Seven Absolute Spirit Slaughter Array from the storage bag, and begin to arrange these two large arrays, and after a burst of brilliance shone in an instant, Luo Yu arranged it extremely quickly, only to see that the outside of the cave mansion was completely shrouded by two rays of light, and after Luo Yu hid the light of the formation, if he didn't search carefully, he wouldn't find anything abnormal here.

With the protection of these two large arrays, Luo Yu believes that it is very difficult for ordinary foundation building period immortal cultivators to break in, of course, Luo Yu does not expect to rely on these two large arrays to resist the attack of a foundation building period immortal cultivator, and now it is to defend against the invasion of some mountain beasts, so as not to have wild beasts that do not know whether they are alive or dead when they sleep.

When Luo Yu finished arranging the formation and tried the defensive nature of the formation, he turned his head to look at the door of his cave mansion, thinking about something.

But soon, Luo Yu shook his head and walked in, doing nothing.

It turned out that just now, Luo Yu wanted to engrave a favorite name outside the cave, after all, it was his own hard work, and it was also a small witness, but Luo Yu then thought that his current cultivation was not yet in the foundation building period, so he rashly named the cave mansion, in case an immortal cultivator in the foundation building period passed by and discovered this place, although it had the support of the senior brother, it was also a trouble.

Your cultivation is not in the foundation building period, and it is only natural that others will rob your cave mansion.

Therefore, Luo Yu felt that it was better to wait until he succeeded in building the foundation before he came to name his cave.

Now that he has the protection of the formation, Luo Yu just found a little dead branches and weeds at random to conceal the entrance of the cave, and there should be no problem, after all, who would build the cave at the foot of the mountain, not the top of the mountain with the best aura, Luo Yu did the opposite, which was very unexpected.

In the end, after all this, Luo Yu felt that time was really fast, it was getting dark, and his cave was in the dense forest of haze, and his vision was blurred as if he had fallen into the middle of the night, seeing this, Luo Yu decisively ran into the cultivation room, and without saying a word, he took out three futons side by side, and fell asleep after laying them out, and when his eyes were closed, he felt that his troubles were gone, and the string that kept vigilant in the secret realm was completely loosened.

Luo Yu soon fell into a deep sleep, the corners of his mouth raised a faint smile, Luo Yu slept very soundly, because he knew that in the immortal cultivation world where the wind and rain were coming, this might be a rare relaxation for him in the future.

The cave is quiet and tranquil, but in the dense forest outside the cave, birds, beasts, insects and fish are quietly doing things day after day, carefree.

"Immortal Flame" has a way to go to school today, and I can finally restore two shifts for everyone, go to school today to adjust one day, and two shifts tomorrow!
