After successfully handling the recruited tunnel masters, Su Yu no longer has any worries.
Accompanying Qin Xian'er and Su Cai'er, after spending a few days of leisurely and comfortable life, they decided to retreat.
He took out Shaohao's time-accelerating magic weapon and activated it.
Suddenly, the time within the secret room accelerated ten thousand times!
After spending 40,000 years here, the outside world has only spent four years.
This is the longest retreat journey in Su Yu's life.
Taking a deep breath, Su Yu took out a thick pile of information on the Rosette of Overwhelm and strived to fully master the refining method of the Rosette of Overwhelm within 40,000 years.
He formed a seal with one palm, and a Su Yu who looked exactly like him appeared next to him.
It is the clone that is transformed from the soul.
Enlighten the matter of the Lotus Seat of Crossing Og and leave it to him.
As for the real person.
Su Yu's heart moved and he entered the portable storage space.
There, a lifelike snow-white fox was lying there peacefully.
Beautiful and noble, it makes people worship.
Among the eight tails behind it, one was broken off and missing.
Su Yu made a move with his palm, and the severed tail flew from somewhere else and landed in his palm.
Back then, the remnant soul of the Nine-Tailed Emperor tricked Su Yu into taking her and his body to the demon world.
Just to reunite the body with the last lost tail.
In this way, the remnant soul can completely control the corpse and indirectly resurrect the Nine-Tailed Emperor.
Unfortunately, Su Yu saw through it and destroyed it.
After many years.
Su Yu once again faced the corpse of the Nine-Tailed Emperor.
"The blood of the Emperor can be used as the oil in the oil lamp of the holy body of mortals." He murmured: "The Buddha of Ten Thousand Lamps gave me the light of the lamp with his lifelong power, but he did not give the flame the oil to continue burning."
At this moment, he somewhat understood why the oil lamp withered.
A fire without roots can only burn for a short time.
Only as long as the lamp oil lasts forever, the light will never go out.
Half a drop of the emperor's blood is only enough to last an oil lamp for half an hour.
So, he needs more.
He had tried the body of the Nine-Tailed Emperor, but with his current ability, he couldn't even move it.
Trying to refine the emperor's blood from it is as difficult as ascending to heaven.
However, this truncated tail can still be tried.
With a thought in his heart, Su Yu took out the Nine Dragon Divine Cauldron.
Place the severed tail in it and use the eight realms as flames to refine it.
Time is like water.
In the accelerated state, time flashes forward ten years.
Su Yu's body was covered with dust.
He still persists in refining his tail day after day.
But, ten years have passed.
The tail remains docked.
There is no sign of being refined at all.
Not even the coat color has changed.
It seemed as if all Su Yu's efforts in the past ten years were in vain.
But he didn't give up.
The oil lamp is one of the most powerful weapons in his life as a mortal saint.
If there is even a shred of hope, never let it go.
Another ten years have passed and the tail is still the same.
Thirty years have passed!
Forty years have passed
Fifty years have passed...
When a full hundred years passed, finally, the tail changed.
The snow-white hair began to show a faint bluish-black color.
It took a whole hundred years to refine the hair until slight changes occurred.
Su Yu had been half buried in the scattered dust for half a year.
Unless he controls the fire in the domain, it will burn continuously and steadily.
Everyone doubts whether he is still alive.
In this way, refining continues in an orderly manner.
Another hundred years have passed.
Boredom did not defeat Su Yu and did not make him want to give up.
The color of the fur with the chopped tail is already darker, but it is still far away from being refined into the emperor's blood.
Three hundred years have passed!
Four hundred years have passed!
A whole thousand years have passed.
The space has been turned upside down, and countless creatures have already completed dozens of transitions from birth, old age, sickness and death.
The place where Su Yu is located has been buried by dust and has become a small hill in the process of natural evolution.
In the mountains, the truncated tail finally showed a very obvious change.
All its hair was refined until it withered, fell off, and turned into black smoke.
All that's left is the bare fox tail.
Thousands of years have passed before the skin was refined and peeled off.
The skin must be refined and peeled off to get a glimpse of the emperor's blood!
The refining difficulty of skin will be several times that of hair!
Su Yu took a long breath and fell into the endless boring refining again.
A thousand years have passed.
The skin of the fox's tail only showed a little burnt mark.
It’s still an unknown number of years before it completely melts!
Thousands of years pass by silently.
The small hill where Su Yu is located has become a mountain.
In the mountains.
In the Nine Dragon Divine Cauldron in front of Su Yu, the skin of the fox's tail has been completely burnt black.
However, no trace of the emperor's blood has been refined yet.
Thousands of years of hard work may result in nothing.
Su Yu's heart couldn't help but be shaken.
Will sacrificing such a high price result in failure?
no way!
There was a great rebellion in his heart.
If ten thousand years doesn’t work, then twenty thousand years until the emperor’s blood is refined!
Su Yu gritted his teeth and continued refining.
Another ten thousand years have passed.
The skin of the tail was just more charred, but there was still no blood of the Emperor.
Su Yufa was cruel and would not give up until the time came to an end.
The 30,000th year has passed.
The skin is as black as coke.
When the 40,000th year has passed.
Finally, there was a scratch, and the dark fox skin, which was as black as coke, finally broke into a hair-thin crack.
A trace of nine-colored blood slowly flowed out from it.
The blood of the emperor!
Su Yu suddenly opened his eyes, a hint of joy filling them.
After forty thousand years of continuous refining, it finally succeeded.
He immediately collected the first drop of the emperor's blood.
When you notice that time is accelerating and slowly receding, immediately seize the time to continue refining.
A thousand years later.
The second drop of the emperor's blood was refined.
Five hundred years later.
The third drop of the emperor's blood was refined.
One hundred years later, the fourth drop of the emperor's blood was refined.
As the refining reaches the end, the skin becomes more and more fragile, making it easier and easier to refine the emperor's blood.
Unfortunately, the effect of the time-accelerating magic weapon has finally ended.
The time inside the secret room has become the same as the outside world.
This means that the four-year period has arrived.
The battle for time dominance is about to begin.
Su Yu could only let it go temporarily.
However, after 40,000 years of refining, this layer of fox skin has become increasingly fragile.
In the future, with his ability to accelerate time a thousand times, he will be able to refine a drop of the emperor's blood in about half a year.
His 40,000 years of hard work are not in vain.
Look at the clone again.
As early as a hundred years ago, the clone had stopped comprehending.
Because all the books were learned in 40,000 years.
"Go back!" was the command.
The avatar returns to the original body.
Su Yu rubbed his extremely tired head and slowly walked out of the secret room.
After 40,000 years, there is an unprecedented layer of vicissitudes and stability in his eyes.
Outside the secret room.
Eight hundred Taoist masters, Queen Xingyu, Qin Xian'er, Su Cai'er and others were waiting outside the door.
"Congratulations to Mr. Su for leaving the country!"
