Mu Chen naturally wouldn't be as Lin Baiyuan thought, at this time he had already driven the heavenly coffin and Nie Shushu to the bottom of the waterfall.

"It's really a miracle! I've seen the river flowing backwards in books before, and although I really felt it a year ago in the Trapping Dragon Yuan, the waterfall flowing backwards is really unheard of! This underground world really can't be inferred by common sense. Mu Chen couldn't help but marvel as he looked at the water flowing upstream.

"Young master, don't patronize this backward waterfall. In front of you is an endless underground river, and you can't even see the bank. Let's be careful. Nie Shushu reminded.

Mu Chen nodded and said, "Sister Shushu said yes, but now you can't even see the shore here, and my aunt's trace has disappeared without a trace." However, it is a good place to understand the meaning of the dragon's form. ”

"How long can the young master control the coffin?" Nie Shushu suddenly asked for no reason.

"At most, half a pillar of incense time. Mu Chen didn't know why Nie Shushu suddenly asked this question, but he still said truthfully.

"Most of the time for the incense stick...... That should be enough to save your life. Nie Shushu said with a jaw.

"Saving your life?" Mu Chen couldn't help but ask, as he didn't understand Nie Shushu's words.

"Yes, young master. Even in the small swamps of southern Xinjiang, there are one or two exotic beasts. If the situation is not right, I can help the young master drag it for a while, and the young master will have no problem driving the coffin to save his life. Nie Shushu said seriously.

"Sister Shushu...... I'm also a master of the mimicry realm now, even if I encounter a seven- or eight-grade beast, it won't be a problem to maneuver around with the dragon body method. And the mimicry realm is the time when you need pressure, can you not always think about letting me run for my life? Mu Chen suddenly said with some dissatisfaction.

"Young Master, this is the underground world, don't think about looking for pressure here. The young master wants to comprehend the meaning of the dragon form in the fight, this is not a good place!" Nie Shushu saw Mu Chen say this, and immediately persuaded him.

"Sister Shushu, the water is not deep, and if there is a dragon, it will be spiritual. Brother Dong had said before that the meaning of the dragon shape could be comprehended in the place of the big river and the big river, and it would have twice the result with half the effort! How could there be such a big river in my southern Xinjiang on weekdays! This underground dark river is an excellent place for me to understand the meaning of the dragon shape!" Mu Chen sniffed the unique breath of the big river under the heavenly coffin and said with a little excitement.

"Young master is here again......" Nie Shushu shook his head helplessly, got off the green jade coffin, and thought helplessly, "Young master is good everywhere, it's just that this young man's heart is sometimes really a newborn calf who is not afraid of tigers......

Mu Chen saw Nie Shushu get out of the heavenly coffin, so he put the lightning purple gold marten back into his arms, and then took the green jade spirit coffin and carried it back behind him, stepped on the dragon swimming method, and quickly walked on the underground dark river, this speed was like walking on the ground.

"Young Master, just leave whatever you say!Wait for me!" Nie Shushu shouted from behind.

"Haha! It's so enjoyable! Feeling the breath of this big river, I feel that I have a deeper understanding of the meaning of the dragon form!" Mu Chen said excitedly as he ran.

"Young Master, you move quietly!Don't really lure out the strange beasts at the bottom of the river!" Nie Shushu shouted anxiously behind him.

Mu Chen didn't think so, what he wanted was to lure out some high-grade beasts! Because he felt that his dragon swimming body method needed more pressure and stimulation!

What better stress and excitement than a high-quality beast chasing behind your ass!

Opportunities are always reserved for those who are prepared, and this saying has been passed down since ancient times, and it has not disappointed to this day. The same is true today!

I saw that the water behind Mu Chen began to ripple, and he followed closely behind Mu Chen.

"Young Master, be careful! there's something behind you!" Nie Shushu shouted behind Mu Chen.

"Hehe, sure enough, it's here, let's see what kind of goods are first!" Mu Chen said, and the speed under his feet was deliberately slowed down a little.

I saw that the ripples were getting closer and closer to Mu Chen, but it was only a dozen breaths of effort that was about to reach Mu Chen's heels!

The tips of Mu Chen's ears moved slightly, and the sound of water brought by the ripples naturally couldn't hide from Mu Chen's ears.

Mu Chen suddenly accelerated, saying that it was too late and that it was fast, just when Mu Chen had just accelerated, a fish fin was exposed at the closest ripple to Mu Chen, and in an instant, a huge fish head burst out of the water!

The fish had a bloody mouth wide open, and its mouth was full of fangs, and the fish head was the size of an ordinary water tank!

"Evil beast, Hugh hurt my young master!" Nie Shushu snorted and slapped at the big fish.

"Sister Shushu, it's just a six-grade carnivorous ghost pomfret. As Mu Chen spoke, several carnivorous pomfret jumped out of the water and headed towards Mu Chen and Nie Shushu respectively.

Mu Chen didn't mean to do anything when he saw the man-eating ghost pomfret attacking, and he dodged around on the water with the dragon swimming method, and his movements were very elegant.

And looking at Nie Shushu, there is no threat to her, Nie Shushu is a ghost body, although now in the ghost realm, you can condense the entity, but you can switch freely between the virtual and the real!

"Sister Shushu, don't hurt these guys, the Carnivorous Ghost Pomfret Clan of the Sixth Rank is just right for me to refine the Dragon Swimming Body Technique again!" Mu Chen watched Nie Shushu separate the corpse of a carnivorous ghost pomfret again, and suddenly spoke.

Nie Shushu shook his head helplessly, obviously Mu Chen didn't listen to her previous words at all.

In this way, Nie Shushu floated in mid-air, while Mu Chen was stepping on the water with the dragon swimming body method and constantly moving forward, behind Mu Chen, dozens of six-grade carnivorous ghost pomfret jumped out of the water from time to time, revealing a bloody mouth and biting towards Mu Chen, but Mu Chen was able to avoid it dangerously every time.

After chasing Mu Chen for several miles, this group of carnivorous pomfrets suddenly stopped for some reason, and swam back without the slightest hesitation.

Mu Chen looked at the background of their departure suspiciously, and wondered: "Why don't these guys chase after them, my dragon swimming body method is being used like a fish in water!"

"Young Master. Nie Shushu floated down to Mu Chen's side from mid-air, and said with a smile, "The strange beasts of the sixth rank also have a little bit of intelligence, they gave up when they saw that they couldn't eat the young master's meat after chasing for so long." ”

Mu Chen shook his head, looking at the calm river here, and a smile floated.

"What is the young master laughing at?" Nie Shushu asked puzzled.

"Although the carnivorous pomfret only has six grades, they are ferocious by nature, and they are alien beasts that live in groups, and they have never been in the habit of giving up food that is fast to their mouths. If so, there is only one case. Mu Chen glanced at the surface of the river and said thoughtfully.

"What's the situation?" Nie Shushu asked suspiciously.

"That's when they feel the aura that terrifies them, such as seven, eight, or nine strange beasts!"

As soon as Mu Chen's voice fell, the calm water suddenly boiled!
