Disappointed, Nie Fei looked down a little bit, and the genius earth treasure in the yellow-level treasure house couldn't enter Nie Fei's vision at all. All that's left is the last book.

These books may have exercises, secret techniques, and even secrets that are rarely known.

"The thunder knife technique, using the power of thunder and lightning to condense the blade, after practice, it is like thunder, invincible. "It looks good, but it's not a weapon that Nie Fei usually uses.

After that, Nie Fei continued to look at the next one.

"Burning blood**. "It's another exercise that relies on self-harm in exchange for short-term strength, too.

"The sword saint is proud of the evil past. "What is this, Nie Fei was speechless. Can this thing also enter the treasure trove?

......

In the end, Nie Fei selected two swordsmanship among thousands of treasures, although the level was not high, but it was very useful to the current Nie Fei.

One is the mad demon swordsmanship, and if you don't go crazy, you can't live. Seek a breakthrough in the madness, this is a bizarre swordsmanship. The reason why it is placed in the Yellow Tier Treasury is because it has a high probability of failure. Few of the people who cultivated it were able to awaken from the realm of madness.

However, once someone successfully cultivates the mad demon sword technique. Then his strength will increase faster than a meteor, unimaginably fast.

The other is the Blood Slaughter Sword Technique. As the name suggests, the sword is a sword art that advocates killing, and the more people you kill, the more powerful the sword technique will be.

This swordsmanship is completely a swordsmanship that uses human lives to pile up, if you kill enough people, then I'm afraid that the general earth-level swordsmanship can't compare to him. The only drawback is that once you can't control your heart, you will be turned back by swordsmanship, and thus become a slave to killing.

However, for Nie Fei, who has a demon-killing inheritance, this is simply the same as nothing. Could it be that he will still be eaten by the nourishment of his own demons?

This swordsmanship is simply tailor-made for Nie Fei, as for the problem of killing. Have you ever seen a cultivator who doesn't kill?

In this cruel world, if you don't kill someone, you will be killed by others, not to mention that Nie Fei is also tasked with rebuilding the Flame Demon Palace. There are still so many enemies alive in the world, if you can't quickly improve your strength. Who should avenge the revenge of the Flame Demon Palace?

"That's him. Nie Fei said suddenly. He immediately told the female cultivator who received him about the Blood Slaughter Sword Technique he had chosen.

"Please wait. The female cultivator said. Soon, a piece of jade slip was presented on a tray and brought over.

"What is recorded here is the Blood Slaughter Sword Technique, please put it away. The female cultivator said.

"Thank you. Nie Fei put away the jade slip and turned around and left here. Before that, he had already chosen his next assignment. It's also an unlimited mission, but this time it's much more dangerous than before.

"Go to Chifeng Island to catch the blood centipede. The reward is 2,000 points each. "Obviously, there are a lot of blood centipedes here, so naturally it can't be the blood centipede that Nie Fei has been looking for.

However, Nie Fei believes that since the two of them have the same name, it is very likely that they are related.

After leaving the Brave Association, Nie Fei, who couldn't wait to study the Blood Slaughter Sword Technique, immediately found an inn.

"An inn. Looking at the plaque above his head, Nie Fei couldn't help but be speechless. This store is really straightforward.

After Nie Fei entered, he directly threw a high-grade spirit stone, "I'm going to find a room to rest." ”

Without saying a word, the shopkeeper directly led Nie Fei into a tidy room, neatly and neatly, without the slightest drag. Just like its plaque.

The room is clean and tidy, and the service attitude of this inn is really good. Nie Fei sighed.

Immediately, he transferred all his energy to the jade slip in his hand. I have to say that this way is really convenient. However, the vast majority of jade slips are rubbings made of copies, and few people will record the precious material exercises in the jade slips.

It's more about using traditional books. Because although the jade slip is convenient, it cannot perfectly reflect the artistic conception and implication of the writer. Therefore, whether it is precious information or exercises, all of them are recorded in books.

And such things are often lonely, and once there is an accident, it will be ruined.

It would be nice if Jade Jian could record everything like a book, Nie Fei couldn't help but think. As everyone knows, after countless years, Nie Fei's thoughts are really out of sight. All the books have been replaced by jade slips, but it is too early to say these things.

"The sword is a fierce soldier, and it is ...... to kill into the Dao" is different from the swordsmanship, and the opening of this swordsmanship explains that the sword is a murder weapon.

In fact, it is true, no matter how nice it sounds, the sword is not always used to kill? Since it is killing, it will inevitably produce evil energy, and how can a sword with evil energy be said to be a benevolent and righteous soldier?

What this sword technique advocates is killing, and he inspires cultivators to kill. It is wrong to kill one person, and it is wrong to kill ten thousand people and bear it. Killing 9 million people is a bear of bears.

Absorb the blood and evil energy of your opponent after killing them to increase your power. It never ends, that is. No matter what realm Nie Fei cultivates to, as long as he kills enough people. Then the power of this sword technique will also increase with the improvement of his strength.

Moreover, even Nie Fei doesn't kill people now. The power of this Blood Slaughter Sword Technique will not be low either. Because Nie Fei inherited the demon killing inheritance. But in terms of killing and evil spirit, how many people can compare to killing demons?

Nie Fei, who was immersed in swordsmanship, once again fell into a mysterious realm, and the essence of the Blood Slaughter Sword Technique was being comprehended by him little by little.

......

When Nie Fei slowly woke up. It was getting dark.

"I didn't expect that it would take me a day to thoroughly comprehend the essence of this Blood Slaughter Sword Technique. Absorbing the lessons of the past, Nie Fei also devoted himself to cultivation this time, but he also deliberately left a trace of divine sense to calculate the time outside.

After finishing his cultivation, Nie Fei immediately flew towards the sea. It's a pity that there is no ready-made opponent to let him experiment with power. Otherwise, you can experience the true power of this Blood Slaughter Sword Technique.

However, Nie Fei believed that when he arrived on Chifeng Island, there would be nothing else. There will definitely be a lot of candidates for the trial.

Fortunately, Chifeng Island is not very far from Nie Fei's current distance. The excited Nie Fei stayed awake all night and rushed directly from Heavenly Desolate City to Chifeng Island.

Chifeng Island got its name not only because of the large number of blood centipedes living on the island, but also because of the thunder that surrounds the outside of the island all year round.

No one knows when it started, and a thick layer of thunderclouds wrapped around the periphery of Chifeng Island. The terrifying thunder and lightning in the eyes of ordinary people are just a small battle here, and there are thunderbolts the thickness of buckets everywhere, and the power can be imagined.

Sitting on the island is like being in a prison of thunder. The purple pillars of light are intimidating, and the flickering thunder lights illuminate the entire sky. It is as good as day. No one dared to challenge this thunder. Because the idiots who dare to compete for the power of heaven and earth in everything have been split into powder alive by the thunder.

In particular, the master who is about to break through is far away from this Chifeng Island, for fear that the thunder outside the island will not find a target and vent his anger.

Although the thunder and lightning outside the island are extremely strong, for some reason, there are two passages in the thunder and lightning in the sky. Everyone travels through these two lanes.

Don't look at the fact that there is no thunder and lightning now, once someone breaks out of the passage, then he will have to experience the wrath of thunder.

According to the information, the target of Nie Fei's mission this time is to grow on this island. To be honest, Nie Fei had always been terrified when he passed through the thunder. No one can resist this thunder in the sky, at least not Nie Fei.

The newborn sun slowly rises over the sea level. The soft sunlight turns the sea golden. But that's the end of it. Heavy thunderclouds block out sunlight, and flickering lightning replaces it.

As a result, the sky on Chifeng Island is extremely dark, no matter day or night, all you can see on Chifeng Island is the shimmering purple sky.

"Whew. Nie Fei let out a heavy breath on the ground of Chifeng Island as he passed through the passage outside the island. Nie Fei's heart has been hanging high, for fear that any unsightly thunder will hit him, it will not be a fun thing."

The air on the island is so humid that it even gives you a sticky feel. There is no other reason. Chifeng Island is shrouded in thunderclouds all year round, and there is no sunlight at all, and it is surrounded by sea areas. It's no wonder that the air isn't humid.

"Roar" A huge beast roar came from not far away, and the voice was full of anger. Drew Nie Fei's attention to the past.

In the blink of an eye, there was another huge beast roar, but this time it was obvious that its voice no longer had the same confidence as before, on the contrary, it began to become a little panicked.

Nie Fei walked forward quickly. The beast's roar began to sound continuously, and the roar became more and more rapid. At first, the beast's roar was full of energy. Then he grew weaker and weaker, and his roar grew weaker and weaker.

Just as Nie Fei had approached the place where the beast's roar came from, the beast's roar had come to an abrupt end.

After finishing his cultivation, Nie Fei immediately flew towards the sea. It's a pity that there is no ready-made opponent to let him experiment with power. Otherwise, you can experience the true power of this Blood Slaughter Sword Technique.

Nie Fei flew over quietly, only to see a huge bull lying on the ground twitching constantly, but Nie Fei didn't feel the slightest vitality from him, obviously dead. It was covered in blood, but Nie Fei didn't find any wounds.

Suddenly, the bull's head jerked. Nie Fei, who watched it, was stunned, it was clearly dead, how could it move? ?

With a "plop", a big hole suddenly broke in the throat of the brute, and blood sprayed all over the ground. A centipede, the size of an arm, emerged from the large hole in the bull's throat.

The centipede's red carapace was stained with the blood of a brute bull, and it looked terrifying.
