The Strongest Upgrade System

Long Fei made a bold move, and the blade of the realm king swept across the void.

hoo hoo hoo!

The nine dragons roared, going up vertically and horizontally, wantonly impacting the sky-piercing sword formation.

And Long Fei's figure was also set off against the dragon, soaring into the sky, and then chopped down with a knife.

"Fall into the fairy!"

Tongtian strikes another sword.

Boom boom boom.

The sword light collided with Sword Ray, the sword light and the sword shadow, slammed the sky.

"Crazy Dragon Town Realm!" Long Fei slammed into a rage, and stabbed again.

At this time, once the Wild Dragon Town came out, it was definitely not comparable to the previous one. Today, the mad dragon that was cut out is still only ten thousand feet tall, but the terrifying aura is several times more tyrannical than before.

With a knife swung, the arrogant aura directly suppressed the heavens and the earth between the roaring dragons, as if there was no existence between the heavens and the earth that could accommodate this power, the real madness in the sky.

"Extreme Immortal!"

Tongtian is methodical and strikes another sword.

At this moment, the Tongtian Sword Array has already made three swords, and under the three swords, the power of infinite terror has completely erupted.

Brush brush.

Immortal Zhu, Immortal Trapped, Immortal Jue, the power of the three swords has been displayed, the sky is shattered between one sword, and the void is bursting between one sword. And Long Fei's methods are equally extraordinary, especially after breakthrough, the power of immortality is also fully displayed. Everyone is like a dragon, the avenues of life, and morality surrounds Long Fei. At this moment, Long Fei is the master of Taoism, representing the life of the common people.

war.

Rumble.

Rumble.

Boom! The continuous void was shattered, and the endless sky was trembling constantly at this moment, pale and empty. At this moment, whether it is Long Fei or Tongtian, they all know that the critical moment has been reached. No matter who it is, as long as the means can't keep up at this time, the result will be

will fail.

"Slaughter Immortal!" Tongtian's voice sank.

boom!

Four swords came out, and the real terror finally came.

At this moment, the four swords of Zhuxian are condensed in one line, and the four swords are like one sword, commanding the heavens.

"Boy, even when it was the Conferred Gods, I didn't force the four swords of this sect to unite. Now that I use it to kill you, you can be proud of yourself." Tongtian said in a deep voice, and there was a sense of pride and lingering in his voice.

There was even a hint of contempt.

It seems that under this sword, even Long Fei has to bow his head obediently.

Long Fei's eyes narrowed, and a cold feeling swept through his body.

The hanging sword in the sky is at stake!

That's what it feels like.

As soon as Zhu Xian's four swords came out, the oppression suddenly increased sharply. Even Long Fei felt the shock of his soul, and even the coffin of immortality trembled slightly, as if he had been provoked.

boom.

The next moment, the breath of the coffin of immortality moved, directly smoothing the breath.

Long Fei's eyes also returned to calm.

"Are the four swords out?"

Long Fei's heart tightened.

At this time, all Long Fei's means have been exhausted, and now the fourth blade of the Realm King's Blade cannot be condensed. Therefore, the third sword, the Dragon Slash, could not be used.

The only sustenance is the special power of the Demon Slayer Sword.

However, the conditions for activating the Demon Slayer Sword's skill are too harsh, and it can only be activated when one's own vitality is less than 30%.

"Master, use the Demon Slayer Sword. This time, I integrated the system, and I have checked and filled the gaps, and cleared the previous level of the Demon Slayer Sword. It is equivalent to returning to the factory and rebuilding it. Under the condition that the previous strength remains unchanged, the level is directly attributed to third. -level."

At this moment, the voice of the system girl appeared again.

"Fixing the gaps? There is also a bug on the Demon Slayer Sword?" Long Fei was taken aback.

If it wasn't for the system girl who said it, Long Fei would feel a little unbelievable. "Yes master, the Demon Slayer Sword has risen to eighth-level in the heavens and the world. Later, after the system was updated, it was redefined as fifth-level, and then it devoured the evil spirits in Anubi, the god of graveyards again on Earth. Charm, can be upgraded, although the strength increases

, but the level has not changed, which also affects the power of the Demon Slayer Sword to a certain extent. "The system girl explained.

"Well, you said that too. Is that a bug in the system?" Long Fei asked. "I can't tell, because you also know the origin of the Demon Slayer Sword. It is the world of Tongxian, where endless cultivators' killing intent is immortal, condensed on withered bones. This power is somewhat special, and it has always been in an inactive state, so cause the system to

The level judgment cannot be determined. "The system girl said.

Long Fei was stunned for a moment, and immediately understood.

Just like many times in the game, the hidden attributes of equipment are generally useless if they are not deliberately excavated.

"What about now?" Long Fei asked.

In this case, facing the sky-reaching sword formation, the system girl reminded herself to use the Demon Slayer Sword, she would never aimlessly, she must have her intentions.

"Now I have filled the loopholes in this area. In the Demon Slayer Sword, the killing intent of heaven-defying has also been activated."

"As long as the master uses it, the power is not necessarily weaker than the power of Demon Slayer's World Slash," said the system girl.

Long Fei was stunned for a moment, and then he subconsciously looked at the Demon Slayer Sword.

"Devil Killing Sword third-level."

"Describe the killing intent of the endless powerhouses to conquer the sky, and they are soldiers against the road."

"Skill Slaughtering Demons and Slaying the World. (Nirvana, Cultivation Base, within five small levels of the player, kills instantly. Within ten levels, it has a probability of instant kill.)"

"Special reminder that the demon-killing sword contains the meaning of heaven-defying of the infinitely strong, and it is a fairy. It can be used in all planes of the world. After a fight with Heavenly Dao, its power is increased by 300%. It can be used times, three times."

In an instant, Long Fei was stunned.

This kind of data is simply heaven-defying.

"System girl, what exactly is the Cultivation Base of Tongtian? Is it possible to kill with a single sword?" Long Fei asked. "I can't kill it. Master, although the Cultivation Base of Heaven is only detached from the ninth-level. But he has already entered Heavenly Dao, Heavenly Dao is immortal, Saint is immortal. Even if it is a demon-killing sword, it will destroy its physical body at most, unless you, Master, can kill him. Destroy Heavenly Dao, then Heavenly Dao will be holy

Humans can be killed with a single sword. "The system girl said.

Long Fei nodded.

Although he was a little disappointed by the result, at this time, it was a huge surprise to let him know about the changes in the Demon Slayer Sword.

The next moment, Long Fei's eyes turned, the blade of the realm king disappeared from his hand, and the Demon Killing Sword appeared in his hand again.

"What? Is the donkey out of luck?" Tongtian sneered.

Long Fei didn't pay attention, raised the Demon Slayer Sword in his hand, and pointed at Tongtian, "Activate!"

Long Fei made a faint sound.

And as Long Fei's voice fell, on the Demon Slayer Sword, streaks of mysterious light suddenly erupted, followed by silhouettes, condensing and appearing, looking at Tongtian in front of him, instantly scarlet eyes, killing intent monstrous.

"Dao, Heavenly Dao lackey!"

"Although it is different from my world, I am a cultivator and will never be a slave."

"kill!"

One after another roar, hovering above the void. In an instant, Tongtian's face was horrified, he could no longer keep his calm, and he became extremely pale.
