Lin Yu sat on a stone, looking around and not knowing where to go for a while. Open the map in the star hub, the virtual map expands, and a red icon sits firmly at the edge of the virtual map.

Lin Yu scaled the map, and then he realized that the so-called three hundred kilometers was so far away, if he walked even if he didn't encounter any danger, he would have to walk for ten days and half a month, not to mention that this place was outside the boundary.

He felt a little helpless in his heart, but now that he was being held in his hands, even if he wanted to leave this place, he didn't know how to go, so he might as well do what the black-robed man said.

"The more dangerous the place, the greater the opportunity, this is still my own way, and I have to go on even if I break my teeth."

Lin Yu comforted himself, he was not afraid of death or anything, but he was afraid that his death was not worth it, and if he died in such a desolate place, he was afraid that there would not even be a person to collect the body.

Lin Yu glanced around and breathed a sigh of relief, at least there was no danger in this area for the time being. However, he still took out the Xuanjin Sword from the storage space of the star hub for the first time.

A long sword covered in swarthy flesh was about a meter long and one or two centimeters wide.

However, this weight is not light, although Lin Yu doesn't know how much strength he has now, but at least it is above one or two hundred catties, but he can't pick it up with thirty percent of his strength just now.

"It is worthy of being a blade that can only be used at the third level of the Star Core Realm, and this weight is too physically demanding to kill the enemy."

Although Lin Yu is not too reluctant to hold the Xuanjin Sword in his hand, if he wields it to kill the enemy, he is afraid that his physical strength will also pass quickly, and he will be tired after just holding it in his hand for a long time.

Lin Yu glanced at the Xuanjin Sword in his hand, and then at the star pivot on his wrist, and finally chose to carry the sword on his back.

The whole body of the Xuanjin Sword is made of inferior metal Xuanjin, and it goes without saying that the iron is like clay, and this weight should not be underestimated. Lin Yu has been working hard for the Star Source Envoy, so he naturally knows the information of this Xuanjin Sword.

As the standard equipment of the Star Core Realm Star Source Envoy, the weight of the Xuanjin Sword is different from the first level to the ninth level, of course, this is related to the purity of the Xuanjin used in it.

Lin Yu's Xuanjin sword is second-level, according to what is said in the book, the purity of the sword body is thirty percent, and the weight is nearly three hundred catties, if the scabbard is added, the weight of this sword is nearly four hundred catties.

Generally, those who use the second-level Xuanjin Sword are third-level star cores, so that they can be handy.

Lin Yu had just reached the level of the first level, and the black-robed man gave him the second-level Xuanjin Sword, I really don't know if he did it on purpose or misplaced it. Now he can only use this sword, and it is definitely impossible for the black-robed man to give him a new one.

In the storage space of the star center, there was also a chip on the left side of the position where the Xuanjin Sword was placed, and Lin Yu took it out with a surprised look on his face.

"It's actually a martial arts chip of the thunder-type sword technique and the fire-type fist technique!"

He really didn't expect the black-robed man to prepare him so well, the combination chip of these two martial arts is absolutely sky-high, and it seems that the level should not be low, but Lin Yu has never studied this, mainly because it is the first time he has seen this chip with his own eyes today.

Although Uncle Ye also showed him in the past, he didn't give him a detailed introduction.

The chip was introduced into the star center, and a string of martial arts information disappeared into Lin Yu's mind with the purple and red light emitted by the star center, and pictures appeared in Lin Yu's sea of consciousness.

As the picture emerged, Lin Yu first called the Thunder System Star Source to wield the Xuanjin Sword in his hand, and then used the Fire System Star Source to wield the fist technique. The electric lightning python flickered above the black blade, and the electric light swept across the ground, stirring up layers of smoke and dust.

The fist was accompanied by blazing flames, and the raging fire stimulated the muscles of Lin Yuan's arms, and with a punch, a one-meter-high boulder shattered, and the flames instantly devoured the shattered stones, burning them to ashes.

"Sword skills are thunderous, fire fists are blazing, who are you? This kind of martial art is definitely not something that ordinary people can come up with, so why give it to me? ”

Lin Yu was puzzled, he looked at the traces left by his martial arts in a daze. Although he didn't know what the value of this martial art was, he also vaguely guessed that at least it was a high-quality martial art above level four or higher, which was powerful, and the demand for the star source to release the martial art was also very strong.

Just by the introductory use of these two tricks, Lin Yu felt that the star sources stored in the stardust chain of his thunder and fire systems had been extracted by a quarter each.

Skills are strong, but unfortunately MP can't keep up.

was slandering, Lin Yu's face suddenly turned general, and a few arrows hurriedly escaped from the position where he was standing just now, his steps were too flustered Lin Yu stumbled and fell to the ground, but fortunately he reacted in time and rolled and stood up.

When he looked back at where he had been standing, he saw a dark, strange-looking creature looking at him with blood-red eyes.

The monster was huge, at least two meters tall, with a blue-faced, fanged face, sharp ears, blood-red eyes, and a thumb-sized nostril that breathed a fishy breath.

The muscles were bursting, the two chest muscles were the size of a basketball, and there was a blood-red crystal inlaid in the middle of the chest, and the ruby faintly emitted a cold light under the sun.

The monster's arms were covered with barbs, and a pair of swarthy glowing hands had grown two blade-like stalks, and the blood on them was still dripping, apparently having just been killed. Looking at the blood-red blood, it was obvious that this monster had killed a human just now.

Lin Yu looked at the monster that suddenly appeared in front of him, his throat moved unconsciously, the corners of his mouth twitched, and he didn't know whether it was excitement or nervousness in his eyes.

For him, this was the first time he had actually seen a domain demon alive with his own eyes!

"One-star demon slave-level domain demon, this is here to send experience."

Lin Yu couldn't help the excitement in his heart, although he didn't know the strength of the domain demon in front of him, but there was one thing he could confirm, the strength of the one-star demon slave-level domain demon would generally not exceed the second-level star core realm, and according to his strength, he should be able to barely beat the enemy.

In fact, Lin Yu still had some concerns in his heart, after all, this was the first time he had confronted a real domain demon.

Before Lin Yu could figure out how to deal with it, the one-star demon slave rushed over with a heavy body, looking at its heavy body but not slow.

The demon slave came back with both fists, and the sharp blades on its hands also stabbed towards Lin Yu, as if they wanted to cut open Lin Yu's chest with a single blow.

The Xuanjin sword danced in Lin Yu's hand, and the sword blade picked up the stabbing duo, and when he saw Lin Yu's right foot slammed on the ground, his body jumped up in the air and kicked it.

Who knew that the defense of this demon slave was really strong, Lin Yu's kick seemed to be kicked on the stone slab, this kick did not kick away the demon slave, but instead made Lin Yu pull the old wound in his chest.

As soon as he landed, he endured the sharp pain in his chest and took a few steps back. The demon slave took the opportunity to attack, and its hideous face revealed its desire for food, and the corners of its mouth overflowed with crystal liquid.

"Niang Xipi!"

Lin Yu was angry, this girl looked like she was obviously eating herself. He clenched the long sword in his hand, and the purple lightning in the dantian was stimulated, the red star source showed weakness, and the purple star source was like an angry thunderbolt overflowing from the star core, and it was injected into the bones and flesh of his body along the tendons and veins in Lin Yu's body.

A faint thunderbolt covered the Xuanjin Sword from above his arm, and the dark blade of the sword emitted a formidable cold light.
