The Boundary Source, the core region of the universe, is said to have been originally a singularity in the void space, and it was only after the explosion that the Boundary Source was generated. It was the expansion and radiation of the realm source that gave rise to the current universe. However, compared to the outer universe, the space of the Boundary Source appears to be more solid and mysterious, and the center of the Boundary Source has always been a place that people have explored but have not been able to reach.

The source of the realm, where all matter and life begins.

Qili Star is one of the closest supply points to the Terran Boundary Source, and many explorers and students of the Star Temple will set out from these supply points to explore the Source of the Realm. The source of the realm is a place where there are three things, whether it is the human race, the Doom race, the machine race, or other outcasts and bandits, they are all mixed in it.

In order to protect the source of the realm, many forces agreed that all warships. Spaceship-type vehicles are forbidden to be used in the Boundary Source. In other words, if you want to explore in the Boundary Source, then you can only rely on your own legs.

Some people have been waiting for thousands of years, just to wait for the rain of spirit crystals to shoot out from the center of the Realm Source, so that they can become rich overnight. There are also people who hide behind meteorites, plundering money and killing people to take treasures. No one will care about your life or death, from the moment you step into the Boundary Source, no matter how arrogant Tianjiao is, or how huge the forces behind it, as long as the strength is not enough, they are all ants.

Xia Yu walked around Qili Xing, inquired about some information about the source of the realm in front of and behind the people, and after getting ready, he came to a no-man's land on the outskirts, as an E-level powerhouse, his spiritual power was sprayed, and his body flew towards the sky like a rocket. Until he came out of Qili Star, Xia Yu flew in the direction of the center of the Boundary Source.

At this time, Xia Yu also knew that he was in danger, and anything he encountered here could kill him. If you don't dare to use Sky Wings, the more hole cards you have, the better your chances of saving your life.

After entering space, relying on the magic of the E-level exercise "Stealing Souls", and always replenishing the aura consumed by Xia Yu, Xia Yu's speed became faster and faster, and soon flew forward like a streamer.

In the initial stage, there were still humans from Qili Star around, but as the flight became farther away, no trace of life was detected for a long time, and this flight was ten years.

On top of a meteorite, Xia Yu released Lan Ling'er from the storage space.

"Suffocate me, it's so boring in there!" Lan Ling'er complained.

"There's no way, isn't this a constant rush? When you take a break, I'll let you out as soon as possible! Xia Yu said with a smile.

"It's a good thing, there are a lot of TV series from your Earth, or I'm going to die of boredom!" Lan Ling'er muttered.

"You and the bastard learn a little, it's a TV series again, he's been watching it for thousands of years, and he hasn't seen enough of it!" Thinking of the bastard, Xia Yu also misses the years they walked together very much. But with the improvement of their own strength, they no longer need the protection of artificial intelligence. Lan Ling'er is more often like a personal secretary.

"Huh? Lan Ling'er, go back first, there is a situation! Xia Yu said and sent Lan Ling'er back to the storage ring.

"Xia Yu, what's wrong, is there any danger?" Lan Ling'er's anxious voice came from the earphones.

"It's okay, I just saw that there were aura fluctuations, maybe someone was passing by. Rest assured! Xia Yu comforted.

Since entering the boundary source area, the perception is sometimes very insensitive, and it is not as direct as the Eye of Wangchuan. Just as he was chatting just now, Xia Yu saw an aura fluctuation in the distance, but he didn't know why. If he came by himself, Xia Yu had to avoid it quickly.

The strength of those who can discover the other party before themselves should also be very dangerous. Xia Yu hid his aura fluctuations and observed them carefully.

Three cyborgs are hunting down a human woman. The woman was clearly wounded, and her speed was getting slower, and the three cyborgs behind her were about to catch up.

"It shouldn't be running for me, maybe it's just a passing by, but can I save it?" Xia Yu hesitated when he saw the human being hunted down.

Although he didn't want to provoke, Xia Yu still couldn't control it, before on the battlefield, Xia Yu was also the existence of ten thousand slashes, where could he condone the mechanical clan to kill the human race. So when a few people passed by, Xia Yu got up, accelerated in the air, and directly killed a mechanical person with a knife.

The Terran woman who was being chased saw Xia Yu make a move, and hurriedly turned around and joined forces with Xia Yu. But the cyborg who had been split in half by Xia Yu fused together again. smiled at Xia Yu.

"A stunned young man also wants to be a hero to save the United States, and he doesn't weigh how many pounds and taels he has!"

"High-end cyborgs, as the teacher said, are all liquid metal, if they can't hit the core directly, it is difficult to cause fatal injuries to them." Xia Yu muttered in his heart, and continued to wave the war knife in his hand.

The woman dragged one of the cyborgs in tow, while Xia Yu fought the two. At this point, the battle had begun, and there was no turning back for either side. Needless to say, no matter how high or low, only life and death.

With a guarded auto-people, every injury heals quickly. Not afraid of Xia Yu's attack at all. And after Xia Yu's several attacks failed, he also began to scramble. Scars also began to appear on his body, and although he immediately began to recover under the effect of the immortal body, he looked very embarrassed.

"Find their crystal nucleus, or all attacks will be in vain!" The woman shouted at Xia Yu.

Xia Yu's knife technique swung out again, and the sky sword shadow directly divided the mechanical people into several pieces, only to see a red light flash on the side of a body, presumably where the crystal nucleus was, but it was too late to swing the knife again.

At this time, the attack of another mechanical person also arrived in front of him, and Xia Yu hurriedly raised his knife to block.

"Go!"

Xia Yu waved his hand, and a four-bladed shuttle stabbed towards the crystal nucleus. At the moment when the crystal nucleus was hit, the healing of all bodies began to stop.

Xia Yu rushed and directly cut out the crystal nucleus, put it into the ring, and then put the body of the mechanical person into the special box, and also received the storage ring.

All that's left is to kill the other cyborg with all your might. After having an experience, Xia Yu quickly killed the remaining cyborgs, and although the woman was seriously injured, with Xia Yu's share, she also killed the mechmen.

"Thank you, I didn't expect to meet a good person in the Jieyuan, my name is Xie Wither!" The woman gave Xia Yu a big gift and thanked her with her injuries.

"It's okay, my name is Xia Yu! It's all Terran, and it's normal to help each other! Xia Yu said with a smile.

"Look at the blood you are covered in, recover quickly, I will warn you!" Xie Kuan hurriedly helped Xia Yu to sit down.

Xia Yu didn't actually suffer any injuries, just shed a little blood, but it was not easy to explain, so he sat down on the spot to meditate and recover. And that Xie withered was also sitting next to Xia Yu, looking around at the environment.

Xia Yu was also thinking about the battle with the mechanical clan, obviously the high-level mechanical clan no longer used the low-level method of chip plus mechanical body, an energy crystal nucleus, and a body that could heal at any time, became more difficult to deal with. Moreover, the crystal nucleus can also change its position at will, so it will be difficult to completely kill the opponent in the future battle.

Suddenly, a sharp pain came from his waist, Xia Yu subconsciously jumped up, looking at Xie Wei, who was holding the knife in his hand in front of him, with a surprised expression.

Xia Yu's refining level has also reached the fifth stage, although Xie withered this knife has accumulated power, the injury is not deep, and with the recovery of the immortal body, it has returned to normal in a few moments.

"How so? How can your defense be so high! Xie Wei looked at Xia Yu coldly.

Xie Wei didn't say anything, and continued to hold the knife, wanting to take advantage of Xia Yu's injury and kill him. However, Xia Yu was unharmed, so the two faced each other, and the knives were fatal.

One is to take advantage of people's illness, ask for people's lives, and the opportunity cannot be lost, and the other is a typical angry and ungrateful person, how can there be less than ten minutes.

The woman seems to be weak, but in fact, the attack power is not low, otherwise it would not have survived in the hands of the three mechanical people, presumably, Xia Yu looked a little miserable, the previous battle with the mechanical clan also relied on the imperial weapon, with the four-edged shuttle to open the situation, if it wasn't for the fast recovery of the immortal body, I'm afraid it would have been killed a long time ago.

This situation is also the same, with a single round of spiritual skills, Xia Yu can't take any advantage, but with the strength and recovery speed of his physical body, he is on a par with Na Xie Wither.

Although he was angry, Xia Yu did not use a killing move, the four-edged shuttle in his hand, as well as the Heavenly Wing, and the Thunder Blade were all Xia Yu's hole cards, and the purpose of this trip was to train himself, so as to understand the true meaning of his own martial arts.

This battle has been fought for a day and a night, and Xie has exhausted all his tricks and scheming. even used many strategies such as kneeling on the ground and begging for mercy, getting up and sneaking up, pretending to be dead and deceiving corpses, poisonous smoke and hidden weapons. However, Xia Yu's body is really strong, otherwise this woman would have killed Xia Yu countless times.

Finally, after the woman had nothing to do, Xia Yu also saw that it was useless, and directly killed it with a knife, and then confiscated the other party's storage ring. The corpse was abandoned by the meteorite, and it floated away.

"What a vicious, sinister woman, if it weren't for some hole cards, today would be the time to die!" Xia Yu also had a palpitation in his heart, thinking about being afraid.

After recovering, Xia Yu once again approached the depths of the Boundary Source You. I haven't seen anyone for more than ten years, and finally sat down and rested on a small continent.

The so-called unpredictable weather in the sky, people have good fortune and misfortune, Xia Yu, who has always been smooth sailing, has been in crisis step by step since he came to the source of the realm, and he is possessed by the moldy god. As soon as they landed on this small land, a dozen or so people surrounded them. Above, left and right are besieged.

Xia Yu looked at the people besieging him, most of them were E-class lifeforms, but the level should not be low, and there were two F-class lifeforms dressed in black.

But what made Xia Yu feel the most palpitations was that there was also a white-clothed F-class Terran life outside the crowd, sitting there looking at the starry sky, ignoring everyone. Judging from the spiritual pressure that was inadvertently emanated, Xia Yu felt that he was not an opponent.

"Boy, what's the matter, report yourself!" A man in black shouted.

"This old brother, kid Xia Yu, is a homeless person! I don't know if you've disturbed you again, I'm really sorry! Xia Yu arched his hand and said.

"Wanderer, okay, I'll let you go this time, leave the storage ring, go back!" The man waved his hand.

Presumably, seeing Xia Yu's weak strength, he was very kind.

"Guys and gentlemen, the kid really has nothing of value, fortunately there is still a little spirit crystal, give it to your brothers, and leave the ring, after all, there are still some personal belongings." Xia Yu said.

"Hmph, the oil cavity is slippery, kill!"

The man in black was not really a good person, where did he have time to talk to Xia Yu poorly, so he gave an order directly. As soon as he gave the order, someone from the E-class life next to him took the lead in smashing it with a stick, and Xia Yu dodged it, and the war knife was also in his hand.

"It seems that it can't be negotiated!" Xia Yu said coldly.

"Our boss said that in the realm source, there is only life and death, and there is no transaction! Do it! The man in black laughed.

For a while, more than a dozen people besieged him, and Xia Yu raised his knife to block, but there were a large number of comers, and Xia Yu was sent flying out with one blow, and smashed directly on the rocky mountain on the land. Xia Yu spurted out a mouthful of blood, Xia Yu wiped the blood from the corner of his mouth with the back of his hand, and looked at everyone and laughed.

"Haha, good, let's do it!"

"This kid is a little weird, don't stop, go!"

The man in black saw that Xia Yu received such a heavy blow and just spit out blood, so he knew that it was not easy to get along, how could a person who had been killed for a long time not pay attention to these details, so after explaining, he led people to rush up.

"It's been a long time since I've been so excited, come on!" Xia Yu spread his wings behind him and shouted at everyone.
