Creek Boundary.

Xu Jia and Fu Jing'er have already entered the Xiaohe realm, but the scene that catches their eyes is surprising.

The name of the river boundary is "small river", but the river inside is not a river in the ordinary sense, but a ...... Styx!

The sky in the river realm is always gray without the sun, moon and stars, but the actual scene does not look bleak, precisely because the Styx that can be seen everywhere on the ground is reflecting a faint purple light.

The purple light shone on the faces of Xu Jia and the others, as if to dye their faces purple and become like devils.

"This, is this hell......" Fu Jing'er couldn't suppress the fear in her heart anymore, and wanted to hide behind Xu Jia to seek refuge, but she couldn't let go.

Xu Jia was looking around, he hadn't been to Xiaohejie, but he had heard some rumors here.

The area of the small river boundary is very small, and as the master said, it is a "small world" at best.

Not to mention that compared to a world like the Azure Realm that sits on multiple star fields, even the planet Zhonghuan Star is afraid that the surface area is larger than that of the Xiaohe Realm.

If the Azure Realm is an adult man, then the Xiaohe Realm is at most a bacterium parasitic on the man's body.

On the other hand, the ecosystem of the River Realm is extremely primitive, or because of the water of the River Styx everywhere, it is difficult to give birth to regular life forms here.

The water of the River Styx has a strong dead air, and even if an alien life stays for too long, it will gradually lose its vitality, and it is itself the opposite of the living being.

Of course, where there is light, there will be shadows, and vice versa.

The River Styx in the small river realm is vertical and horizontal, but it has the most extreme source of life, that is, the original essence of the Fountain of Youth, which is wanted by both male and female.

At the same time, it is also Xu Jia's goal.

This is because as long as the original liquid of the Fountain of Youth, which is processed and made into a real Fountain of Youth, it will become a treasure that is of great benefit to the human body.

Although the Fountain of Youth, as its name suggests, makes people "immortal", it can greatly enhance the body's ability to recover, strengthen the physique from the root, and also have a certain effect of prolonging life.

For martial artists, the Fountain of Youthfulness can also cleanse oneself and broaden the meridians, making the flow of internal breath more natural and easier to spread outside the body.

This effect will have an extremely important impact when breaking through the seventh order.

To put it simply, a martial artist who has taken the Fountain of Youth, when he ascends from the sixth order to the seventh order, he will basically not encounter any bottlenecks, and the breakthrough will become a matter of course.

Xu Jia knew early on that the qualifications of his body were not very good, and the historical "Orr" had not achieved much in martial arts.

If you want not to be stuck by the threshold of the seventh order, you naturally have to prepare early.

"I don't want to stay here forever, so I just take the time to find something. Xu Jia said indifferently.

Perhaps realizing that there was only one last road left in front of him, Fu Jing'er gritted her silver teeth, and finally resolutely took the first step forward, and then ......

"Fu Ying! these water ...... These waters will kill people if they touch them!"

Fu Jing'er's screams came from the front, and she couldn't control herself anymore, so she quickly ran behind Xu Jia.

It turned out that the tide of the Styx River was rising, and she was not too careful when she stepped on it, and the tip of her right foot touched a drop of Styx water, and a small piece was dissolved on the spot.

Xu Jia ignored her, just casually threw the hook claw, and under the "hook sickle", the hook claw firmly hooked the rock of a nearby island.

The topography of Xiaohejie is actually composed of islands, and Xu Jia and the others are looking for the smallest island.

The water of the Styx is constantly pounding, and the gravel is stacked towards the center, and the poorer ones will gradually melt into the Styx, leaving only the hardest part of it, forming the Stygian Rock.

As time passes, the Stygian Rock moves closer to the center from all sides of the island, and the island gradually shrinks in size.

When the island is small enough to a certain extent, the surrounding Stygian Rock arches together, and there is a chance to produce the Fountain of Immortality in the center.

In principle, the Fountain of Youth's essence is a part of the elements in the water of the Styx, which is produced by penetrating through the cracks in the Styx, and it is not an exaggeration to say that it was born out of the water of the Styx.

"Go up. Xu Jia handed the handshake of the rope to Fu Jing'er, said to her, and motioned upwards for her to stand on a high place.

Fu Jing'er came back to her senses, at least there would be no Styx water in the high places, so she hurriedly ran up holding the rope, thought about it and said unconvinced: "You...... If you are so fierce to me again, I will let you fall down!"

"Whatever, you won't survive if I die. Xu Jia replied nonchalantly, it's not his body, he really isn't afraid of death.

Without saying anything more to Fu Jing'er, he took out a ferrule, hung it on the rope, and slid directly from a high place, sliding straight over the River Styx.

It wasn't until his feet hit the ground that Xu Jia let out a heavy breath.

If you want to walk in the river realm, it's really good to rely on this method, because it's basically the only way.

In the lifeless river realm, the magic energy cannot be effective at all, and props such as flying machines cannot be thought about, so they can only rely on the internal breath of the warrior himself.

The technique of "hooking and sickling" is best coordinated by two people, and it will be very troublesome to use alone.

In addition to the Pluto Rock, there is basically no fixed fulcrum in the Xiaohe Realm, and the height of the Pluto Rock may not be suitable every time, so it is better to bring more people over.

After Xu Jia landed, he withdrew the hook claw, and threw it to the opposite side, fixing it on the island where Fu Jing'er was.

So this time it was her turn to use the collar and follow the rope across the River Styx.

It was in this way that the two began to travel through the River Styx, looking for smaller islands step by step, but never to gain anything.

"Hey, do you remember the way you came?"

has been shuttled more than a dozen times, Fu Jing'er looked at the unchanged Styx and islands around her, and her tone couldn't help but be a little worried.

Xu Jia just nodded, he remembered the route very clearly, and looked at Fu Jing'er with a little doubt.

Until now, he didn't see what role Fu Jing'er had, or why those two chose her.

"Maybe it's not because Fu Jing'er is special, they just want to find a more talented person to quickly learn the hook and sickle?"

"Found it!" Fu Jing'er's eyes suddenly lit up, and she pointed in a certain direction excitedly.

In the midst of a purple scene, a faint white light suddenly appeared, which was indeed very invigorating.

"Is this the case?" Xu Jia frowned.

He remembered that in his previous life, at the last moment, it was Fu Ying who brought back the Fountain of Youth, not Fu Jing'er.

If it is according to the normal historical development, the current position of the two should be reversed, and it is Fu Jing'er who uses the hook sickle.

"Hurry up and hang the hook over! What are you doing in a daze?"

Xu Jia nodded with a smile, stretched out his hand to hang the hook claw on the island in front of him, but said in his mouth: "You go first." ”
