Prompt: "On behalf of the free day squad, postponing the mission execution period by 1 day requires 80 special permission points, and the upper limit is 100 days, how many days do you need to postpone?" ”

In the form of a squad, using this mission extension privilege requires 8 times more special privilege points than an individual!

Fortunately, Xin You's special permission points are quite abundant.

After thinking about it for a while, he asked, "After the exchange, if I feel that the extended time is not enough, can I continue to exchange it when the time comes?" ”

The female voice belonging to the intelligent assistant sounded in his ears: "Yes, as long as the total time of exchange does not exceed 100 days before you perform the Mandatory Heavenly Dao task." ”

"Okay, then let's exchange it for 10 days first." Xin Youdao.

"On behalf of the free sky team, postpone the mission execution period for 10 days, and need to consume 800 special permission points, can I redeem it?" The ethereal voice belonging to the Heavenly Dao sounded in Xin You's ears.

"Redeem." Xin Youdao.

"The exchange is successful, and the Heavenly Squad will enforce the Heavenly Dao mission after 13 days." An ethereal voice said.

Just as Xin You was communicating with Heavenly Dao, the cold wave had already begun to summon Yin soldiers.

One after another, Yin soldiers dressed in gray leather armor and with pale faces walked out of the diffuse dead air.

"Coldwave, what are you summoning them out for?" Mugo on the side asked.

Han Tide continued to summon the Yin Soldiers as he explained, "Refining so many Nine Condensation Yin Evil Pills at one time, I can't do it alone, and I need them to give me a hand." ”

Mu Ge thought for a while, and then said, "You can only use one Dan furnace for alchemy, why do you have to use so many Dan furnaces?" With just one Dan furnace, you'll be much easier. ”

Han Chao glanced at him, and said in a muffled voice: "If you think you are very good, will you come to refine this Nine Condensation Yin Evil Pill?" ”

Mugo: "I was wrong......

After summoning almost 20 Yin soldiers, the cold wave began to set up.

The array flags embroidered with demons and glowing with a ghostly light were taken out of the storage ring by him, and then inserted into the soil by him one by one.

"Formation, this is the first time I've seen the legendary formation, what kind of formation is this?" Mugo leaned over again and asked like a curious baby.

Xin You, who had redeemed his special permissions, also looked over here.

"This is a very simple formation, called the Heaven Covering and Cultivating Evil Array, covering the sky means that this array can isolate the inside and outside, and the Cultivating Evil Formation can gather the evil qi and yin qi to refine the Nine Condensation Yin Evil Pill." Cold Wave explained.

The formation was quickly arranged, and a thick gray mist rolled up in an area of thirty meters, which shrouded the cold tide and those Yin soldiers, as well as the alchemy furnaces one by one.

This gray mist has a strong shielding effect, even if Xin You opens the Void Eye, he can't see through this gray mist.

Standing outside this sky-covering cultivation array, the light in Xin You's eyes disappeared, and he said, "Let's go, don't disturb the cold wave alchemy." ”

"Okay." Mugo nodded.

In the next few days, Xin You and Mu Ge were not idle.

Because of the Nine Condensation Yin Evil Pill, an artifact of 'open hanging' cultivation, Xin You didn't need to waste time cultivating Ling Xiao True Yuan, so he devoted himself to the cultivation of Sword Technique.

He sat cross-legged on the soft grass, and deduced the killing move in "Sword Fighting" over and over again - the sound of sword roar and thunder.

It is said that once this killing move is practiced, as soon as the flying sword comes out, it will be accompanied by the sound of thunder, and even the heavens and the earth will change color!

Of course, these sound and light effects are still secondary to Xin You, what he really values is the effect of the killing move of the sword and thunder.

Killing moves are different from ordinary moves, and they have their own magic.

According to the record of "Sword Fighting", once the killing move of sword roaring thunder sound is practiced, the flying sword will naturally melt into the void, the speed of the flying sword will not increase much, and the power will not increase much, but the trajectory of the flying sword will become elusive, and with the interference of the surrounding thunder sound, the flying sword is very easy to escape the enemy's lock, killing people by surprise!

Under normal circumstances, flying swords have no other characteristics except for their speed.

When the speed is 10 times faster than the supersonic speed, with the blessing of the terrifying kinetic energy, combined with the sharpness of the flying sword itself, it can easily kill those enemies whose defense is not too strong.

But that's about it.

Once the enemy's perception is sharp to a certain extent, and the reaction speed is fast to a certain extent, and he can resist the attack of the flying sword with weapons, claws, etc., the attack of the flying sword is a little weak.

At this time, the sword roar and thunder sound, the killing move in "Sword Fighting", is particularly important.

Once the sword roar and thunder sound is cast, the flying sword melts into the void, avoiding the enemy's perception, the thunder sound is piercing, disturbing people's minds, and interfering with the enemy's perception, the two are superimposed, it is definitely a nightmare for those enemies whose perception is not too terrifying!

A very simple example.

A powerful warrior can easily avoid the swords, guns, and clubs that attack him through his eyes and through the sound of the wind heard in his ears.

But once he was surrounded by darkness where he couldn't see his fingers, and when he was surrounded by an extremely noisy environment, could he still rely on his perception to avoid the knives, guns, and clubs that attacked him?

It was precisely because he sensed the horror of the killing move of the sword roaring thunder sound that Xin You was eager to practice this move.

He had a hunch that once he practiced this killing move in Sword Mastery, even if his Ling Xiao True Yuan was only at the consummation level, he would be able to easily kill the vampire Delu!

Xin You was sitting on the grass, practicing and comprehending the sword control technique, while Mu Ge was trying to confess his 1-star Spirit Treasure-level Shadow Knife with blood.

The closer the strength is to the human king level, the higher the success rate of dripping blood to recognize the master.

Mu Ge's current strength is a 6-star human male, which is much stronger than Xin Youlai during the Shura World period, so it only took less than an hour for him to let the Shadow Knife successfully recognize him as the master.

Acknowledging the Lord is only the first step, if you want to exert the strongest power of a Lingbao-level weapon, the owner of the weapon must also communicate with the spirit in the weapon.

It's a long process that takes time to build up.

Mugo became familiar with his new weapon by practicing the killer moves he had created over and over again.

Mu Ge in cultivation no longer has a hippie smile, but a serious face.

Little by little, time passed.

Seven days have passed in the blink of an eye.

On this day, Xin You sat cross-legged on the grass, and the Blazing Flying Sword was under the control of his mind, drawing a mysterious trajectory in the sky in front of him.

In the sky, there was a faint sound of wind and thunder.

Suddenly, the Blazing Sword turned from extreme movement to extreme stillness, and stopped in mid-air.

Xin You turned his head slightly and looked at the corner of his private domain.

Almost at the same time, more than ten meters away, the air twisted, and Mugo, who was holding the Shadow Knife, also escaped from the void and looked at the corner as well.
