The Valkyrie chariot drifted in the Wyvern River for two days. At night, they sail up to the riverbank, light a bonfire, and eat and rest.

In the past two days, it has been smooth and smooth, there have been no accidents, and I can drift four or five hundred miles along the river every day, and I have already left the ice field and entered the Gobi zone.

That night, Salha said: "I'm afraid I'm going to enter the underground river tomorrow, shall we continue to drift down the river or follow the water veins on the ground?"

Murong Feng asked, "Isn't it very good to drift down the river, if you trace the water veins from the ground, isn't it quite laborious?"

Salha replied: "Last time, because I didn't have a boat, I had to choose to walk from the ground, and this time although we have a Valkyrie chariot, no one has ever walked through the underground river, and it is really difficult to know what the situation inside is." I was worried about the potential dangers, such as air currents, water potential, or even whether there would be any monsters underground, so I said that. ”

After hearing this, everyone felt that Salha's worries were not unreasonable. I started researching how to choose. In the end, after analysis, it was believed that it was better to continue to take the waterway, because the total length of the underground river was two or three hundred miles, and at the speed of the Martial God chariot, it could be crossed in more than half a day. After the Valkyrie chariot is completely enclosed, the defense is amazing, don't worry about the monsters in the water, and the air in the carriage is enough for everyone to breathe. If you go by land, it is time-consuming and laborious, and you also have to trace the water veins, which is not advisable.

After discussing and deciding, everyone carefully reviewed the plan again, and felt that there was no problem, so they decided to choose to take the waterway.

On the second day, not long after hitting the road, I saw that the river was gradually narrowing, and a huge hole appeared in front of me after a while. It's dark inside, and you can't see it clearly. Du Wu let the Divine Beast Yemen and the Five-Colored Sacred Cow enter the carriage, and even the Divine Eagle Wudian became a passenger in the car. This time, the carriage was finally filled, and there were not many more empty spaces.

Du Wu and the others completely closed the carriage from the inside and drove into the hole. There is a row of small windows on the side of the Valkyrie chariot, made of transparent crystal, and everyone looks out from the crystal window and sees a strange scene.

I saw that the top of the cave was higher at the beginning, and it could be three or four zhang away from the water surface, and many white stalactites hung down from the top of the cave, such as the mountain peak standing upside down, and like a sharp sword hanging upside down. This kind of scene is the first time everyone has seen it, and they can't help but be amazed.

Gradually, as we went deeper into the cave, the light became fainter and weaker, and it was no longer possible to see anything outside the car. Du Wu took out the holy water spirit bead in his arms, held it up to the small window, and exercised the internal force to urge the power of the holy water spirit bead, only to see that on the holy water spirit bead, a blue light emitted, coming out of the window, illuminating the distance of a few zhang square.

Du Wu took out the holy water spirit bead There is another meaning, the holy water spirit bead is the treasure in the water, if there are any dangerous creatures in this underground river, I am afraid that they will also turn around and walk away.

Through the light of the Holy Water Spirit Bead, it could be vaguely seen that as we went deeper into the underground cavern, the roof of the cave became lower and lower, almost touching the roof of the Valkyrie Chariot. Today, half of the body of the Valkyrie Chariot is underwater, and there is still a height of about a zhang on the water. The low part of the roof of the cave is almost only the length of a person's arm higher than the roof of the car.

Seeing this situation, Murong Feng said: "If we encounter a low place on the top of the cave for a while, we will cast a jack pendant together to let the chariot sink, so as not to hit the roof of the cave, although the Martial God chariot is extremely strong, but such a collision will inevitably affect our forward speed." ”

Everyone claims to be.

After walking for a while, I didn't encounter a place where the roof of the cave was too low, but there was something unusual in the river.

There were a lot of small fish in the water, and their bodies emitted clumps of phosphorescence. It looked like the stars in the sky had fallen into the water and fluttered there. All the people who had ever seen such a spectacle were amazed. Several girls were so shocked by this beautiful scenery that they could hardly breathe, and their mouths opened wide and could not be closed.
