In addition, being in the water is also affected by water pressure, and the lack of oxygen is also a key factor, which is much more difficult than cultivating on land, and the requirements for the body are invisibly increased.

Cultivating in such a situation, coupled with the bonus of aura, the effectiveness of cultivation has increased exponentially.

However, breathing in water is a troublesome problem.

At first, the three of them had to go up every hour to breathe fresh air, but after getting used to it, Zi Su and Zi Yun could last up to two hours, like Yu Feng, three hours was no problem.

Under water, Shiso mainly cultivates Zixia True Qi, and the dragon's blood True Qi has now cultivated the gods, and what is most needed is spiritual nourishment, and relying on the martial dragon ring to directly absorb the heaven and earth aura in the jade, the cultivation progress of Zixia True Qi is very fast, and before you know it, it is already a pregnant realm.

Now, there are two inner pills in the dantian of perilla, one is fiery red in color, and the other is dark purple, when the spirit bodies in the two inner pills are completely ripe, the double martial souls are formed, in fact, this is not very difficult for people with double souls.

Ziyun's cultivation is naturally Zixia True Qi, and cultivating in such a place with a strong aura, she has also improved extremely quickly, and in the middle of the night, she actually broke through to the ground-level Martial Saint.

Only Yu Feng, even if she absorbed a lot of aura, but the level she was at was too high, and there was almost no obvious change in these auras for Gang Qi and martial souls.

......

Late at night, Zi Su quietly left the underground river and returned to the Xuanhuang Palace, because his spirit felt the call of the nine-winged blue bird, and he promised her to tell him at least one Journey to the West every night.

"Lord Shenniao called me in the middle of the night, did you want to listen to the story of Journey to the West again?"

"Let's put the story aside, do you know, the map that Qing Ling gave you, the two exits are now inexplicably blocked, what does this mean, it means that you have to find the exit again by yourself when you go out now, and you find that no, they don't block anywhere, they specifically block those two exits, which means that someone is operating in the back, and he must be very familiar with the underground palace, who do you think this person will be?"

Shisu groaned slightly, and said: "This person is very insidious and cunning, he wants to use this underground palace to put me to death, even if I am lucky enough to escape, it is likely that after February Erlong will raise his head, and then my reputation will be ruined." In Heishui Province, it is either the Hei family or the Heifeng Village that can do this, but I look at Miss Yan San of the Heifeng Village, who leaves a line in her work and is okay to be a person, it should not be Heifeng Village, then only the Hei family is left, and the most ambitious thing for the Hei family now is the white horse and black god. ”

The nine-winged bluebird was noncommittal, but said, "Your analysis and guess are very reasonable. However, no matter how much analysis and speculation there is, it is better to directly kill all the hostile warriors in the underground palace, so that you can sit back and relax, in addition, it is urgent to find a new exit, you have to act as soon as possible, so as not to be too late to get out, remind you in advance, I promised Qingling, as long as you are not in danger, I will not make a move, everything can only be dealt with by yourself. ”

Shisu said that he knew, and he also had a good idea for the new exit, that is, to take the underground dark river, and the big old turtle was familiar with the route there, and he would take a few of them out of there when the time came.

As soon as Shisu said this, the Nine-winged Blue Bird also expressed his approval, and when the two exits were all closed, it was a good idea to take the underground dark river

As for killing the hostile warriors who broke into the underground palace, this was exactly what Shiso wanted, taking advantage of the dead of night when the people were sleepy, he sent out a killing magic sound and annihilated them in one fell swoop.

Of course, before that, it is necessary to make a mental exploration with a magic voice in order to get the judgment of friend and foe.

"Okay, then you can act, I'll go sleep in my little world. ”

"Isn't Lord Shenniao listening to Journey to the West tonight?"

"Once a day, it's better to wait for tomorrow or twice together, so it's more enjoyable to listen to. ”

"Yes, that's okay, then I'll continue to practice after I finish destroying people, good night to Lord Divine Bird." ”

"Good night!"

After bidding farewell to the nine-winged blue bird, Shisu sat cross-legged on the dragon chair, silently transporting the dragon's blood true qi, and released bursts of free magic sounds that probed the spirit.

As long as it is a living person, it will always make sounds, such as the sound of breathing, the sound of snoring, the sound of talking, the sound of coughing, the sound of movement, as long as there is a sound, it cannot escape the detection of the sound of the free magic.

After a long time of exploration, the entire underground palace, all the warriors from one to the sixth floor were detected by him, this time there were really a lot of warriors who entered the underground palace, roughly calculated that there were more than two hundred, most of them were still on the first floor, a small part was on the second floor, there were only a dozen people on the third floor, and there were only a few people on the fourth floor, and there were only two or three people on the fifth floor, and no one else on the sixth floor had come down except for a few of them, there was no detailed map to want and how to break the formation, and it was not easy to go down to the sixth floor.

By the way, Zi Su detected Miss Yan San, she was actually quite powerful, and she was not affected by the fake map at all, and she went to the fifth layer with her personal girl.

The situation of the hostile warrior's division was detected, and Shiso's midnight killing began.

"Hahahehe, drink haha......"

The two dead soldiers of the Black Family were the first to be attacked by the Demon Sound, and they had no idea that someone would sneak up on them in this way, and they were caught off guard before they could even scream before they were killed by the powerful Demon Sound.

Killing a martial artist,The only benefit to Zisu is the increase in martial arts points,Every time a person dies,The martial arts system will report the change in points,Sometimes it's exciting.,Sometimes it's annoying.,But when you feel annoyed,You can turn off the reminder function of the martial arts list.,There's nothing wrong with that.。

Immediately afterwards, four or five disciples of the Xuanyin Demon Sect also died quietly under the demon sound.

There are all kinds of vicious people on the rivers and lakes, this time they ran to the underground palace, and Zisu will never let them go, they were devastated by a strong magic sound before they died, and they died in a very miserable state, and they were tortured before they died.

The sound of the Demon Sound, for these warriors, is completely one-sided slaughter.

Of course, there are also some masters who know how to resist sonic attacks, but the magic sound is too strong, and the magic sound with the dragon's blood true qi is like an explosion, ringing in their hearts, shaking their hearts inch by inch, spitting blood and dying.

"Who is it, who is attacking us?"

"According to the method of attack, I remember that only the Shiso Divine Doctor will escape the magic sound, it is said that he has already gone down, and he must be the one who is attacking us. ”

"Young Master, what should we do now?"

"Cold salad, quickly plug your ears, sit quietly and resist it, and maybe you can escape the catastrophe. ”
