In the next four days, Lin Quan searched the four broad submarine plains closest to the sea ridge according to the simple seabed map of the "Mengxuanhai" and relevant materials that he had organized.

These undersea plains were not the deepest places in the Mengxuan Sea, but they were significantly deeper than the shallow seas he had searched before, and under this purposeful search, the number of ripe purple moonroes he had harvested was more than twice the total amount in the previous half of the month.

It's just that the number of Golden Branch Blood Bears is still not ideal. It took him another day to visit the deepest trench, and he was able to fill the huge gap a little.

"Xuandou Island" is an inconspicuous desert island on the Mengxuan Sea, Lin Quan returned from the trench and landed on this island, opened a simple cave at random, and began to seize the time to meditate.

There were still nine days left before the closure of the secret realm, and after the five days needed to return and the half-day as an advance amount, there were less than four days left for him. If he moved faster, he might be able to probe the other two trenches in the Mengxuan Sea again.

Two hours later, with the help of spirit stones and a large number of pills, Lin Quan finally recovered the spiritual power that had almost been consumed. With a flick of his wrist, he took out the chart he had put together again, and while checking the location of the next trench, he silently calculated the best route and distance in his mind.

No way, the resources in the deep bottom are very rich, but the huge water pressure on the bottom of the sea is not so easy to bear. Judging from Lin Quan's experience, most of the trial disciples did not have the ability to dive to the bottom of the Mengxuan Sea.

Even if he had cultivated the "Heavenly Demon Floating Slaughter Technique", his physical strength surpassed that of the Great Perfection of Condensation, and he had reached the limit when he dived to the depth of the submarine plain, if it weren't for the help of eight big lizards, he would not have been able to be busy alone. As for the deepest trench, if there was no protection from Xu You, he could only hold on to a cup of tea at most.

Therefore, in order to save some spiritual power, he had to calculate the location of the trench as accurately as possible. After all, flying in the sky consumes much less spiritual power than groping at the bottom of the sea.

After another half an hour, he suddenly put down the jade slip with a frown.

It turned out that among the many documents he had seized, there were considerable discrepancies in the location of the other two trenches, and for a time he could not determine which information was more credible.

Do you want to try all of these sites? But then there is no chance to go to the last trench.

Lin Quan scratched his head in annoyance, and suddenly he had an idea, remembering that the pair of little yin spirits he had newly acquired were the natives of Mengxuanhai, so he immediately summoned them out.

"Fog waves, fog waves, do you know the locations of the other two trenches in the Mengxuan Sea?"

"Of course I know, we've already visited the entire Mengxuan Sea. Fog was a little proud, feeling that he could finally do something for his master.

"Master, the trench is dark and deep, it's not fun at all, what are you going to do there?" Sister Wulan was a little curious, but as soon as she finished speaking, she was pulled over by her sister and glared, and suddenly felt a little aggrieved.

"Hehe, actually, it's nothing. ”

Lin Quan touched the two sensible little yin spirits dotingly, "I need a large number of mature purple mongolas to heal your mother's injuries, and there are many seedlings to cultivate, so I need to find more golden branch blood bears." ”

After speaking, he reached out with his right hand, took out the smallest piece of golden branch blood bear and handed it to the second daughter.

"Golden Branch Blood Bear, is it just for this kind of coral that the owner is looking for the trench?" the two girls suddenly realized, and then said in unison a piece of news that surprised Lin Quan.

"Master, if that's the case, the little slave knows a good place to go. The corals there are plentiful and large, and the quality is much better than what the owner has found. ”

"Okay, let's lead the way!"

Lin Quan couldn't wait to take out the Moyu Light Spirit Boat, "By the way, how long will it take to get there, we don't have much time." ”

"Don't worry, master, it will only take four or five hours at most to get from here to that extinct volcano under the sea. ”

The little yin ghost's affirmative reply finally dispelled all of Lin Quan's concerns, and a moment later, a dark jade-colored light left Xuandou Island and flew into the distance like a lightning speed.

............

The "Molten Heart Cave" is located in the belly of an unknown extinct volcano.

This undersea volcano hasn't erupted in thousands of years, but it's still hot in the belly of the mountain. One of the most famous is the deepest Molten Heart Cave.

On this day, two young monks, a man and a woman, broke in hand in hand. Along the way, he easily killed dozens of "Fire Spirits", "Fire Monkeys" and other first-order fire demons, and then went all the way to the deepest part of the Molten Heart Cave.

By the time we arrived, it was already a world of magma, and the air was scorched into smoke by the furious aura of earth fire, and only a haze could be seen from a little distance. However, the monks and men were clearly prepared, and it was only then that they unhurriedly blessed themselves with a shield of aura, and then walked on the red ground as if nothing had happened.

At the beginning, the road surrounded by magma was relatively wide, and occasionally some cracked gaps would spew out small puffs of fire and magma from time to time, but after walking more than 100 zhang, the road became narrower and narrower, like a single-plank bridge. After walking this curved "single-plank bridge" of at least 200 zhang, a solid platform suddenly appeared at the end. The platform looks like it is a hundred feet in circumference, and it is surrounded by bubbling magma except for the "single-plank bridge" that can communicate with the outside world.

"Shangguan Fairy, that 'one-horned unicorn' is hidden here, and after the little brother lures it out, it will all depend on the great assistance of the fairy. Qian Yin Daoyou arched his hand, and after the blue-shirted girl behind him nodded in agreement, he walked towards without delay.

He calmly walked to the middle of the platform, slowly took out a delicate warm jade box from his bosom, carefully took out a strange-looking little red fruit and put it on the ground, and then took out a lot of small bits and pieces from his arms and began to arrange them around.

The smell of the little red fruit was extremely strange and pungent, and the girl looked at it a few times before she was no longer interested, and turned her head to look at the surrounding environment. If she hadn't owed the other party a favor first, she wouldn't want to go with Qian Yin at all, let alone risk coming to this extreme environment that is compatible with her exercises.

I don't know what kind of spirit fruit this little red fruit is, and when its smell completely dissipated, the originally calm magma suddenly tumbled violently.

Soon, a monster with a single horn and thick black armor suddenly poked out its huge head, splashing the hot magma everywhere, only to see its big nose like a pig twitch a few times, and soon its eyes locked on the little red fruit.

............

Under the leadership of Fog Wave and Fog Lan, Lin Quan urged the flying boat with all his might, and it only took more than three hours to come to the area where the extinct volcano was located. Then he took the second daughter back to the Tai Chi space and summoned Xu You to jump into the sea together.

I don't know what the reason is, there are really a lot of golden bears near this extinct volcano, especially the deeper the place, the easier it is to find, under the protection of Xu You, Lin Quan harvested several pieces of good quality and small coral in just one hour.

"This is really a treasure land that has been developed, fortunately, it is too reluctant to come here with the strength of an ordinary late-stage condensation monk, otherwise these good treasures will be dug up long ago." ”

Digging up several pieces of golden branch blood bear again, it wasn't until Xu You couldn't eat it that Lin Quan pursed his lips and slowly floated up, planning to go back to the sea to rest for a while before coming.

As he floated, he casually looked at this amazing extinct volcano under the sea.

Listening to the two little Yin Spirits, although this volcano had never erupted since they could remember, they could still feel the violent earth fire inside it when they came to play, but because the Yin Spirits were naturally afraid of fire and thunder, they had never seen the volcano for so many years.

"Well, if you have time to spare, let's search this mountain carefully. ”

Just when Lin Quan thought so, he inadvertently looked up and found that there was an inconspicuous hole above the oblique top, and the entrance of this cave was covered by protruding strange rocks all around, if it wasn't for looking from the bottom up, and the angle was just right, Lin Quan wouldn't have found it.

"Hey, there is such a secret cave here, is this the entrance to the extinct volcano?" Lin Quan's eyes narrowed, and he immediately leaned over.

When he got closer, he made a new discovery, only to see the remains of several unknown monsters floating at the entrance of the cave, probably because of the obstruction of the surrounding strange rocks, the corpses of these monsters have not been washed away by the current. Through the corpse, he quickly judged that the demon beast's death time was not long. There are at least two people who made the shot, and their strength is very good.

"Very well, let me see what treasure you are here for. Also, I hope you don't have too little to gain these days. ”

The person who has the strength to find this place and can easily kill these demon beasts must be a powerful elite, thinking of this, he suddenly came to his senses, and he did not hesitate to dive in.

The structure of the volcano was similar to that of a small ghost, and after swimming continuously, he jumped out of the water and landed in a wide lava cavern. Walking along the lava caves that were connected to each other, one or two demon beast corpses could be found almost every other distance, and with these conspicuous "road signs", Lin Quan didn't take much time to come to the lowest level of the lava cave.

By here, he could clearly hear the shrill roar of a beast and the coquettish sound of a woman coming from ahead.

So he took out the "black robe" of "Phantom No. 3" from his arms and covered it on his body, and then changed into Hong Xiaoying's appearance and carefully touched it.

The temperature was so high that the air was foggy, so it took him a lot of tea to complete the lava trail with magma on both sides, and then he looked out to the flat platform in front of him.

"Roar, Roar, Roar, ......Roar, Roar, Roar, Roar, T

With a roar like a dragon's roar, a large area of burning fire is constantly rolling around, and there are two different flashes of yellow and blue in the firelight, and every time the yellow and blue light collides with the firelight, it will make a loud sound, and the beast roar that has never stopped is intertwined.
