Now Luo Zhen should not deal with these monsters too easily, and he specializes in picking up demon emperors to deal with them. In a short while, he hunted three demon emperors in the third level of the Emperor Realm.

Therefore, the demon crystal was obtained.

Luo Zhen looked at the demon crystal that was only one-third the size of a palm, and couldn't help but sigh and said, "Although two of the three demon emperors just now exposed the demon crystal, it's too small, right? I'm afraid I'll have to kill about seven or eight more!"

"Satisfied, your luck is already very good! Take your time!" the system said.

After hearing this, Luo Zhen had to wander around in the forest. After Luo Zhen massacred, dozens of monsters in the forest had been poisoned.

For a moment, no monster dared to come out again, which made him feel a little embarrassed.

"Don't worry, here we come!" The system just finished speaking, a gust of evil wind blew past, cutting off the surrounding trees in the waist, and then a series of strong winds as sharp as a knife rushed towards Luo Zhen.

Luo Zhen naturally noticed that with his agile body, he could easily avoid several strong winds, and then looked coldly at a strange cheetah in the back of his body.

"The Evil Wind Demon Leopard, its back half of its body is composed of wind, and it is extremely fast. It is a natural jungle killer!"

A system prompt sound appeared in Luo Zhen's mind, and then he understood it.

This does fit its name.

The powerful force caused by the strong wind it just blew just now was indeed extremely powerful. The trees around a hundred meters have been cut off, and it seems extremely empty at this moment!

The evil wind demon leopard in front of him is extremely powerful, probably around the seventh level of the Emperor Realm.

The evil wind demon leopard was a little afraid of the "weak chicken" in front of him, because the sneak attack he was proud of did not hurt Luo Zhen, which surprised him a little.

"Boy, why do you want to slaughter the monsters here?" The demon leopard suddenly spoke and asked Luo Zhen.

Even if this monster cannot evolve into a human form for some reasons, it can still speak. This is extremely normal.

Luo Zhen was not surprised, and said lazyly: "It's nothing, I just need your demon crystal, I have to!"

As he said that, a ball of Nine Infant Demon Fire appeared in Luo Zhen’s right palm, and his left hand was wrapped in rainbow-colored Yuanli, looking like he was ready to take action.

"Hmph, since that's the case, there's nothing to say. Let's die humans!"

The next moment, the two went to sumo each other.

...

Luo Zhen threw away the corpse of the evil wind demon leopard, and then held the demon crystal that was half the size of a palm in his hand.

The evil wind demon leopard didn't expect that he would be killed instantly until he died!

After a meeting, Luo Zhen killed him directly. The demon leopard disappeared without even reacting!

Luo Zhen was also shocked. The demon crystal of this demon leopard was so big that one of them was as big as four or five before.

"Nothing is strange. I said that the stronger the strength, the bigger the demon crystal. It is all at the seventh level of the Emperor Realm. It is not surprising that there is such a large demon crystal." The system said lightly.

The system did not expect that Luo Zhen was so lucky. He killed four emperor-level monsters in total, and three monsters all had demon crystals.

This luck is no one else!

Luo Zhen also felt that he was lucky, otherwise he would not have failed to die at the beginning. Instead, he encountered the system and started his awesome journey.

"System, can you upgrade the Hunyuan Xinggang Sword now?" Luo Zhen asked the system with the demon crystal as big as a palm.

"Yes, now the materials can be upgraded to ten Hunyuan Xinggang Swords, but how many do you want to upgrade?" the system asked.

After thinking for a while, Luo Zhen said, "Nine pieces! Equip me with the remaining rainbow stones!"

Now he can only control nine Hunyuan Xinggang Swords at most, and it may be a bit reluctant to form Youquan.

Therefore, upgrading ten pieces is a bit useless, so it is better to equip the Hunyuan Xinggang Sword to increase its power.

"Yes, this is indeed the best choice at the moment." The system also agreed.

After hearing this, Luo Zhen first took out the Four-State Mi Tian Banner to set up a defensive formation. Because time was tight, the defensive formation was not perfect, with only the defense power of the fifth and sixth level of the Emperor Realm.

Then, he quickly arranged an auxiliary formation as if he was first created in the Hunyuan Xinggang Sword, and the sword embryo space appeared again in the center of the auxiliary formation.

Then, according to the system's instructions, first put the rainbow stone and melt it with the Nine Infant Demon Fire.

The Nine Infant Demon Fire is a real immortal fire, but it was useless in the face of the rainbow stone before slowly melting it.

Then, the demon crystal was added again, and after it was burned into the seven-color liquid, the Hunyuan Xinggang Sword was added.

Then remove the Nine Infant Demon Fire and let it soak.

Because the Hunyuan Xinggang Sword is considered a top-grade spiritual weapon, it will not melt so easily. Only the Hunyuan Xinggang Sword can slowly absorb the energy of the rainbow stone and demon crystal.

Half an hour later.

The system prompts that Luo Zhen has been upgraded, and the hot colorful liquid has cooled down at this moment.

Luo Zhen quickly pulled out nine Hunyuan Xinggang Swords, but he saw that the sword itself had not changed much, but there were some mysterious patterns on it.

However, Luo Zhen couldn't understand it, and he didn't care about the strange patterns.

Nine long swords were now standing in the air, emitting a dangerous smell. Then, through the formation, a stream of Yuanli River gathered towards the long sword, and was finally absorbed by the long sword.

The long sword after absorbing the huge amount of Yuan power was like a child who had enough food. It seemed to have strength and suddenly burst out a white light and soared into the sky!

The defensive formation did not play any hindering role, and it shattered with a bang.

Nine white light columns soared into the sky, shocking the entire forest!

The monster kept roaring, looking at the direction of the light column, and then quickly fled to the distance.

For a time, many monsters even ran into the city and ran around, as if they were frightened.

People outside also discovered the abnormality. Even though they were far away, they still felt an invisible pressure in their hearts!

The pressure comes from the white light column!

At this moment, some people's spiritual weapons began to tremble unstoppably, as if they were about to escape from their master.

"What's going on! Why did my knife run away!" A strong man didn't pay attention, and his scimitar cut through the sky and flew out of the city.

And there are more than one, at least nearly a hundred spiritual weapons in the city are flying away at a speed outside the city, and the scene is extremely spectacular!

All spiritual weapons have spirits, and their sense of imitation spiritual treasures is far more than that of ordinary people!

So they were even more afraid of Luo Zhen’s nine long swords and wanted to escape from here.

"There are problems with those light columns, go and see what's going on!" A patrol guard captain found something wrong and asked his subordinates to run towards the forest where Luo Zhen was.

"I've been hurt, the noise is getting big. Let's go quickly. I don't want so many people to know that I have an imitation spiritual treasure!" Luo Zhen said, and then he quickly thought about it, put away the imitation spiritual treasure, and quickly used the earth escape technique to escape to the city.

It’s not that Luo Zhen is afraid, but she just doesn’t want to make it known to everyone in the city and causes too much trouble.

The guards had just reached the forest and found the corpses of monsters everywhere, some of which were extremely tragic!

There is a place that is even dyed red with blood, extremely cruel!

"Captain, look, that is the evil wind demon leopard, at least the strength of the seventh level of the Emperor Realm, and he died!" A guard pointed to the demon leopard who died tragically on the ground and said to the captain.

Seeing this, the captain observed for a while and found that the situation around him was like someone deliberately killing them, not hunting!

In the new world, there are generally few monsters that have not transformed into humans, so ordinary citizens are generally prohibited from killing randomly.

Only when some people from major forces want to hunt and inform the city lord's mansion can they go in with the guards to hunt.

But the scene in front of me was obviously not hunting, but slaughter!
