After exhaling softly, Lu Yu said:

"System, improve the realm!"

"Ding! The host does not meet the advanced requirements, and the advanced fails! ”

What?!

Lu Yu was stunned for a moment, his performance points had obviously exceeded 1.5 million points, why did he fail to advance?

"Ding! To advance to the seventh-order Ghost King realm, the host needs to strengthen the Shura Golden Body and the Dark Spring Ghost Mist to the sixth time, the Infernal Blood Pupil and the Flame Hell Flame to the third time, and the Water Resistance to the twelfth time before they can be promoted! ”

"Poof——!

Hearing the system prompt sound in his head, Lu Yu directly spurted out a mouthful of old blood.

The system has never said that there are preconditions for promotion to the seventh rank.

Each of these abilities is a big kryptonite family, and after such a set, it is estimated that there is not much left of this 1.8 million.

However, Lu Yu thought about it and felt that such a condition was also reasonable, after all, the seventh-order ghost king realm not only had to condense his own ghost king true body, but also stimulate his own ghost domain.

If it was really possible to advance so easily, then there wouldn't be so many ghost hunters trapped in the sixth order in this world.

After taking a deep breath, Lu Yu spoke:

"System, strengthen the Stygian Spring Ghost Mist to the sixth time!"

"Ding~! After deducting 420,000 performance points, the Dark Spring Ghost Mist has been successfully strengthened! ”

Hearing the prompt sound in his head, Lu Yu felt that his heart was dripping blood, and he calculated that the fourth strength of the Dark Spring Ghost Mist should be 60,000 performance points, then 120,000 and 240,000 in turn.

It adds up to 420,000.

This special daddy is too money-burning, and there are Shura Golden Body, Infernal Blood Pupil and Hell Hellfire that need to be strengthened.

"Isn't this 1.8 million enough?"

As soon as such a thought appeared in Lu Yu's mind, he felt that his body suddenly spread out in all directions, and his consciousness instantly flew into the air.

When Lu Yu came back to his senses again, his whole body had turned into a black mist floating in the air at an altitude of 10,000 meters.

Looking down from above, the entire lockdown is like the size of a fingernail, and the view of money has long been invisible.

Lu Yu closed his eyes and felt his state, incomparably light, incomparably comfortable, feeling that he could ride the wind at any time and fly to a higher place.

"Is this what it feels like to ride through the clouds, it's really good."

Before, he could also use the Stygian Spring Ghost Mist to fly, but he couldn't reach such a high place at all, and his speed was not fast.

And now, Lu Yu feels that he can fly at a high speed.

The Stygian Spring Ghost Mist, which has been strengthened to six times, is already so powerful, what kind of atmosphere would it be if it was strengthened a few more times?

Although these 420,000 made Lu Yu's heart drip blood, but after really seeing the effect, he felt that it was very worthwhile, worthy of the ability of more than 400,000 krypton, it was awesome!

Then, Lu Yu spent another 420,000 to strengthen the Shura Golden Body.

This time, the effect of strengthening is more obvious, and the defense and strength become stronger, and when the reinforcement reaches the sixth time, a pair of arms grow on Lu Yu's back again.

Now he's a head and six arms!

Lu Yu guessed that a second head should have grown during the seventh strengthening.

He also vaguely had some guesses that the Shura Golden Body should be related to the true body of the Ghost King, and the Ghost Mist of the Dark Spring was related to the Ghost Domain, so the system would put forward such a precondition.

Thinking like this, Lu Yu suddenly realized.

So he spent another 260,000 performance points to strengthen the Infernal Blood Pupil and the Infernal Flame three times each.

The initial strengthening points of these two abilities were as high as 10,000 points, even higher than the Shura Golden Body and the Dark Spring Ghost Mist, and Lu Yu felt that his blood pressure was going to rise for a while.

The first three times were so much, and that side still got it?

He didn't believe that when he was promoted to the eighth rank, he only needed performance points and didn't improve his own ability.

Even the most ordinary ability to resist water cost him 350,000 performance points, and this enhancement cost Lu Yu a total of 1.4 million performance points.

In an instant, he returned to the pre-liberation period overnight.

[Host]: Lu Yu

[Age]: 22

[Realm]: Sixth-Order Demon (0/1.5 million)

[Performance points]: 405100

[Items]: Ghost Ghost's Baseball Bat +6 (Enhanced), Hanged Ghost's Rope +6 (Enhanced), Black Wind Spiritist Banner (Enhanced), Red Ghost (Enhanced), Thousand Phantom Ghost Faces (Enhanced), Ghost Scholar's Jade Pendant (Enhanced), Shadow (Enhanced), Glare Mirror (Enhanced), Doll for the Dead Ghost*1, Ghost Pure Water*1, Blood Orb,

[Skill]: Infernal Blood Pupil +3 (Enhanced), Water Resistance +12 (Enhanced), Concealment (Enhanced), Stygian Ghost Mist +6 (Enhanced), Asura Golden Body +6 (Enhanced), Hell Flame +3 (Enhanced)

Although he did not advance to the seventh order, after this wave of strengthening, Lu Yu's strength was more than doubled.

But if he encounters a character like Hu Zhenfeng again, Lu Yu can hammer him with one hand.

After strengthening all his abilities, he turned into a cloud of black mist and quickly fell from the sky, quietly returning to his room, without alarming anyone.

"There are still 400,000 performance points left, and according to the recent period, the rate of harvesting 200,000 performance points every night, at most, I can be promoted to the seventh rank in four or five days."

Thinking about it like this, Lu Yu's heart was not so uncomfortable.

He glanced up at the ghost gate in the sky, and secretly prayed in his heart, hoping that the old locust tree's qi would not disappear so quickly, and he must be stronger, otherwise his performance points behind him would not be settled.

And at this time, the city is locked down in an extremely secret room.

Yuan Chengshan and Kong Wanting stood very respectfully in front of an old man, this person was none other than Gu Yangming, the head of the Gu family.

He unexpectedly came to the lockdown from the imperial capital.

"Master, you're finally here!" Yuan Chengshan's face showed a little excitement.

Because Gu Yangming's arrival meant that their multi-year plan was about to come to an end, Yuan Chengshan had been waiting for this moment for a long time.

And Kong Wanting knelt on the ground and said:

"My subordinate has lost a blood refining bead by negligence for a while, please punish the head of the family!"

When Gu Yangming heard the words 'Blood Refining Beads', a touch of gloom flashed on his face, but his expression quickly returned to normal, and then said lightly:

"It's okay, it's just a blood refining bead, I will personally take it back from Lu Yu's body at that time, but you, who have been working hard in the lockdown for more than ten years, have worked hard for you, don't worry, after I am promoted to the eighth order this time, I will definitely help you achieve the seventh order realm."

Hearing this, Kong Wanting's breathing suddenly became short, isn't this the result he has been waiting for all these years?

His head was lowered, and he said loudly:

"Thank you to the head of the family, my subordinates will do their best to serve the head of the family!"
