A month later in the space-time room on the fourth floor of the Heavenly Demon Tower.

A large amount of blood-colored murderous aura filled the space, wrapping Su Fan in the inner and outer three layers.

Behind Su Fan, there were two blood-colored sword shadows, one large and one small.

At this moment, he was trying to merge the smaller sword shadow into the larger one.

The slightly larger blood-colored sword shadow was the eight-style fusion sword shadow in front of the Mad Demon Nine Killing Sword.

And if Su Fan can also integrate the last sword shadow into it, then it means that the new improvement of the Demon Sealing Nine Killing Sword will be completely completed.

The integration of nine styles, this kind of improvement, is undoubtedly equivalent to creating a new sword move.

Therefore, this last step is very crucial, and once it fails, it can only be a waste of all the previous efforts.

"It's a little bit closer, what's wrong?"

Su Fan's lips were pursed, and his brows were deeply locked.

At this moment, a large number of sword moves appeared in his mind, and he was practicing different sword moves according to Su Fan's various conjectures.

"It's still not right, it's all wrong, can it be that this sword technique can only be fused to the eighth move at most now?"

Beads of sweat oozed from Su Fan's face, and his comprehension of the fusion sword move had caused a great load on his mental power.

The reason why this is the case is not that Su Fan's spiritual power is too weak, but because the power of the Nine Killing Swords of the Mad Demon is extremely strong after the fusion of the nine moves!

It is so strong that the grade of swordsmanship after fusion has surpassed the top threshold in the world, and it is a lot higher than the pseudo-divine skill!

Su Fan originally thought that after the integration of the nine styles, the Mad Demon Nine Killing Sword could only reach a level comparable to the Great Perfection of the First Form of the Thunder Three Slashes.

However, when he really started to fuse, he found that every time this sword technique was fused, the attack power would increase several times.

Until the current integration of the eight styles, the total attack power of this sword technique has completely exceeded the entry stage of the first type of the thunder three slashes by hundreds of times!

Fortunately, Su Fan mastered this sword technique to the Great Perfection, otherwise in just one month, he would not be able to achieve the fusion of the eight swords at all!

Su Fan thought to himself, even if he really learned all the three thunderbolts, he was afraid that he might not be able to reach the current level.

Of course, if the three slashes of the thunderbolt can also be improved, the future development space will not necessarily lose to the Mad Demon Nine Killing Sword.

"The three-day period is coming in a blink of an eye, and I have to work harder!"

Su Fan gritted his teeth and said, although he was slightly dizzy, he still insisted.

After becoming the leader of the alliance, in just a few days, he felt that the burden on his shoulders had become a lot heavier.

At this moment, because the difficulty could not be overcome for a long time, he couldn't help but feel a little impatient.

"Forget it, you force yourself to understand the sword like this, and the result can only backfire, the eight-style unity is actually very strong, and the reason why you can't comprehend the nine-style unity now is just because the opportunity has not yet arrived!"

Youyan had been secretly observing Su Fan's cultivation state, and seeing that Su Fan was now starting to become impetuous, he immediately spoke out to enlighten Su Fan.

"I don't believe it! In the past, the Blood Slaughter Monk was able to completely fuse this sword technique, why can't I? Could it be that my comprehension is not as good as that of a dead man?"

Su Fan roared in a low voice.

In Su Fan's subconscious, he thought that the Blood Slaughter Monk had died a long time ago, and he had killed it himself, so he was unwilling to admit his understanding, and it was better to defeat one of his own subordinates.

"That's just his nonsense to lie to you, I don't believe that there will be anyone in this human world who can combine these nine-style killing swords, because according to the real situation known to the master, even the blood mad ancestor who created this killing sword failed to successfully fuse this nine-style killing sword before he died!" You Yan said.

"What? You mean really?"

When Su Fan heard this, he was slightly stunned, and the bloody killing aura that was entangled around him vaguely faded a little.

"If the master tells a lie, there will be five thunderstorms in the sky!"

You Yan directly swore a ruthless oath: "I believe you have also discovered that every time this nine-style killing sword is fused, the requirements for physical fitness will also be higher, let me tell you the truth, the reason why the blood mad ancestor died back then was because when he fused to the seventh move, his body was overloaded, he suffered a martial arts backlash, and he was killed by the murderous qi!"

"What?"

Su Fan's pupils shrank, and he was secretly frightened.

The situation that Youyan said, in fact, he had already discovered it.

Although his physique was strong, after fusing to the seventh move, he obviously felt a little powerless.

And when Su Fan fused to the eighth move, he could even have a hunch that he couldn't perform this move very smoothly at all.

It can be seen that with his current physical condition, he is unable to bear the serious consequences of the integration of the nine styles.

"Okay, then this time the sword of enlightenment will end here!"

Su Fan said with some unwillingness, and the blood-colored murderous aura that lingered around his body slowly disappeared.

"Uh...... I'm so dizzy, I'd better rest for a day!"

He was about to stand up, but he felt dizzy and had to sit down again.

This time Wu Jian caused a lot of his spiritual power to be consumed, almost to the verge of running out of oil.

Su Fan took a deep breath, ran the Seven Stars Refining Technique, and began to slowly recover his spiritual power.

A day later, Su Fan's face finally improved.

"Alas......"

He sighed and walked out of the space-time chamber.

"Ding!"

At this moment, a system prompt sound popped up in his ears.

Su Fan was stunned for a moment, but then he heard that the system had issued him a brand new task.

"Player Su Fan automatically triggers and receives the seven-star task 'Defeat the Master Who Destroys the Succession Ceremony', please complete it within ten days, if you can't complete it, you will be deducted from the three realms!"

After the prompt sounded, Su Fan's task bulletin board lit up, and he opened it to take a look, and there was indeed a new task on the bulletin block.

Next to the mission name, seven stars are twinkling.

Su Fan rubbed his eyes and took a closer look, that's right, it's really seven stars!

"It's actually a seven-star mission!"

Su Fan was shocked!

You know, he always thought that the highest task that the human world could receive was only six stars.

And in terms of Su Fan's current realm, it takes 700 billion experience points to upgrade to the next level, and he has to do at least seventy six-star missions to upgrade.

But now, there is actually a seven-star mission triggered by him, which is simply unthinkable!

The level of the seven-star mission is high, and the rewards given are also very high, Su Fan took a look at the reward, and the experience value given was 100 billion.

And if he can get these experience points, then the efficiency of leveling up will also be greatly improved!

"Seven-star mission, hehe, I'm worried about having no experience to upgrade now, and the system actually sent it to me so considerately!"

Su Fan instantly became happy, and threw all the troubles of the unsuccessful fusion of swordsmanship into the clouds.
