Coupled with the 10,000 top-grade spirit crystals that were wasted because he was disturbed by the Holy Sky before, Lu Ming spent a total of 70,000 top-grade spirit crystals to upgrade his cultivation from the middle stage of the Martial King to the peak of the Martial King.

In Lu Ming's hand, there were still 80,000 top-grade spirit crystals left.

"Now, start attacking the Martial King Duo!"

With a wave of his hand, another dense piece of top-grade spirit crystal appeared in the air.

This time, Lu Ming took out 20,000 top-grade spirit crystals at one time.

Bump! Bump...

Pieces of top-grade spirit crystals exploded like fireworks, and the incomparably rich aura permeated, all of which were swallowed into the mouth by the Nine Dragons blood.

The majestic energy turned into a rolling true element, and Lu Ming began to attack the Martial King Duo.

Not long after, all the 20,000 pieces of top-grade spirit crystals were refined, and Lu Ming took out another 20,000 pieces.

"It's fast, it's fast, it's just one step away, and you can break through the double of the Martial King. ”

This time, Lu Ming waved his hand and directly took out 30,000 top-grade spirit crystals.

Thirty thousand pieces of top-grade spirit crystals, the energy is terrifying to the extreme, and it begins to impact towards the Martial King Duo.

Half a day later—

Rumble!

With a roar, the aura on Lu Ming's body soared several times, and the Martial King doubled, breaking through.

"The power of the True Yuan is so strong, it is heavier than the Martial King, and it has increased by three times. ”

Lu Ming felt the vast True Yuan in his body and thought in his heart.

No wonder, in the realm of the Martial King, the gap between each weight is very large.

"Now, I only have 10,000 top-grade spirit crystals left on me, and this cost is really big. ”

Lu Ming sighed.

Of course, this is just him, and other people are cultivating, and they definitely don't need so many top-grade spirit crystals.

Moreover, it is also because Lu Ming's thunder artistic conception has already reached the first level of small success, and cultivation can make an unscrupulous breakthrough.

Ordinary people need to work hard to comprehend the artistic conception of heaven and earth, and the artistic conception of heaven and earth will be one step forward, and the cultivation will be one step higher, which is like Lu Ming, the artistic conception of heaven and earth has improved so much at once.

"If only I had enough top-grade spirit crystals, my cultivation could be promoted all the way to the fourth level of the Martial King and become the king of Xiaocheng!"

Lu Ming thought to himself.

But then he shook his head.

As soon as the Martial King is promoted, so many top-grade spirit crystals are required, and the Martial King is double, and the Martial King is triple-promoted, and the top-grade spirit crystals needed will definitely reach a terrifying number.

"It seems that we will have to find a way to get more resources in the future. ”

"Also, this Dandan, since the last time I ate that Heavenly Tribulation, there has been no movement, I don't know what happened?"

Lu Ming picked up the Dandan hanging between his hair and looked at it carefully.

If it weren't for the fact that there was a layer of crystal luster on the eggshell, and there was vitality permeating the stone egg, Lu Ming was really afraid that something would go wrong.

After all, it's a catastrophe.

"Huh?"

At this moment, Lu Ming's expression moved, and then he waved his hand, and a jade box appeared on the ground.

In the jade box, there are two black dead branches.

There is also half a box of clear springs.

This clear spring originally had a box, but now, only half a box remains.

And one of the two pitch-black dead branches soaked in the clear spring actually grew a tender bud at one end.

Yes, one of the dead branches actually came alive and grew a young shoot, and on the young shoot, a little bit of luster shined, making the young bud look crystal clear.

But what surprised Lu Ming the most was that from this young shoot, there was actually a mysterious and mysterious breath, under this breath, Lu Ming's mind was extraordinarily ethereal, and he abandoned everything and placed himself in the avenue of heaven and earth.

In the past, some incomprehensible places in martial arts were quickly figured out by him.

Enlightenment, in this state, Lu Ming seems to be enlightened.

"It's wonderful, it's amazing, what is the origin of this withered branch, it's just a young shoot, it can actually help people to enlighten. ”

Lu Ming was shocked in his heart.

"Now, comprehend the artistic conception of heaven and earth and take a look!"

Immediately, Lu Ming closed his eyes and began to comprehend the artistic conception of the wind.

Immediately, Lu Ming felt that his feeling of the artistic conception of the wind was very clear, and the speed of comprehension was at least ten times faster than before.

"Oh my God, this is amazing. ”

Lu Ming's eyes stared at the young shoot.

At this time, Lu Ming saw that on that piece of shoot, there were wonderful lines, which looked like some real dragons, some like phoenixes, and some like ancient beasts such as unicorns.

It's subtle.

"According to legend in the world, in the primeval era, there was a kind of spiritual root of heaven and earth, called the spiritual root of enlightenment, this spiritual root, will grow into a spiritual tree of different forms, this kind of spiritual tree, there is a general name, called the ancient tree of enlightenment, according to legend, in the ancient times, the strongest people in heaven and earth will plant an ancient tree of enlightenment beside themselves to help cultivate, is it possible that this dead branch fell from a certain ancient tree of enlightenment?"

Lu Ming suddenly thought of a legend.

Thinking of this legend, Lu Ming's heart became extremely hot.

"It can't be true, right? If it's true, then I'm not going to send it. ”

Lu Ming was a little incredulous.

After all, there are too few ancient trees of enlightenment, and in the primeval era, only the strongest people in heaven and earth can master one.

And that kind of supreme power, each of them is incredibly strong, and today's Martial Emperor, in front of such a strong person, is like an ant.

"Keep it secret, you must keep it secret, whether it's true or not, you must not let others know, otherwise, I will definitely die. ”

Lu Ming knew very well in his heart that this section, if it was really the Enlightenment Ancient Tree, the entire Divine Desolate Continent would riot, and those Martial Emperor powerhouses would definitely seize the Enlightenment Ancient Tree at all costs.

Now, just one bud has grown, and the speed of Lu Ming's comprehension can be increased tenfold, so what if it grows two, three, or even more?

How much help will it be for Lu Ming?

Immediately, Lu Ming hurriedly put the jade box into the Supreme Temple, and then the people also entered the Supreme Temple.

"Whether it's a true enlightenment ancient tree or not, but it can increase the speed of comprehension by ten times, it's a fact, this alone is immeasurably valuable, haha, it's sent!"

Lu Ming was ecstatic.

Subsequently, Lu Ming began to comprehend various martial arts again.

Sure enough, under the shroud of the mysterious aura of the young shoots, Lu Ming's mind was extremely clear, and his speed increased by about ten times whether he comprehended martial arts or comprehended the artistic conception of heaven and earth.

"Cultivate, start cultivating!"

Lu Ming put the jade box beside him and began to comprehend the artistic conception of the wind.

He planned to condense the artistic conception of the wind into the artistic conception rune first.

In terms of attack, there is the artistic conception of thunder for the time being, as long as the artistic conception of wind is condensed into the artistic conception rune, his speed will be greatly improved.

In the blink of an eye, three days have passed, and Lu Ming's comprehension of the artistic conception of the wind has improved rapidly, which is equal to the results of the previous comprehension of one month.

But Lu Ming still felt slow.

"If you use this ancient tree of enlightenment, in the palace of enlightenment, with that kind of artistic conception, then the speed of comprehension, is it faster?"

Lu Ming couldn't help but think.

Regardless of whether this is really an Enlightenment Ancient Tree or not, Lu Ming directly called it the Enlightenment Ancient Tree, not for anything else, it sounds cool.

As soon as he thought of it, Lu Ming immediately set off and headed towards the Enlightenment Palace.
