Two days passed quickly.

In the past few days, Lu Qing'an has been traveling back and forth between the Space Field and the Time Cinder Dragon Court he discovered not long ago. While accumulating the crystals of the rules of heaven and earth, he tries to visit the Space Field over there as much as possible, so that he can comprehend the Locking Sky Law later.

Two days passed outside, and more than fifty years passed in the particle secret realm.

Zhen Yongfu produced the Eternal Night Pill by controlling the consciousness puppet. Now he has almost used up all the immortal stones and only has the last batch of immortal pills left. The latest batch of Eternal Night Pills he produced were handed over to Liu Lingxuan by Lu Qingan. Now Liu Lingxuan has also cultivated a group of peak-level Dao Saint Realm powerhouses.

"Start converting your lifespan into the crystallization of the rules of heaven and earth!"

Not only did Liu Lingxuan complete the task, but the Black Dragon also burned all of his holy medicines. In addition, the dragon clan burned a batch of immortal medicines. Last time, he killed 500,000 demon troops. The total lifespan of all these things added up to a lot of time made him feel a sense of vitality that he had never had before.

The life span he now possesses is the longest he has ever had since he came into this world!

The crystal of the rules of heaven and earth that is exchanged will only be available once at most!

He first asked Liu Lingxuan to call the children to the golden giant tree.

A group of children came in a mighty procession, and under the organization of Liu Lingxuan, began to enter the interior space of the giant golden tree.

These children all listened to Liu Lingxuan's words and did as they were told, and almost all of their lifespans that had increased dramatically during this period were input into the conversion space.

Each person only has 100 million years left to live.

Lu Qing'an felt that he was being kind. If these children were left unattended, those with good fortune might, among so many people here, one or two could live to be a hundred years old. Those with bad fortune might only live one or two more years.

They even died miserably the next day in the ice and snow and in the harsh living environment.

Now, with his help, not only have they become Dao Saint Realm peak powerhouses at a young age, but they have also gained an extra 100 million years of lifespan. No matter how you look at it, these kids have profited.

As Lu Qing'an watched these people step forward to offer their lifespans, he wondered if he was too conscientious and couldn't play the role of a capitalist.

After everyone donated their life span, Lu Qing'an stepped forward to check the number of voluntary life spans that could be used. After careful calculation, he nodded with satisfaction.

Just a little bit satisfied.

As he had guessed, human hearts were difficult to control after all, and it was difficult to obtain voluntary longevity.

Among more than two thousand people, the life spans of nearly two hundred people are not counted, which means that there are still people who are unwilling to sacrifice their life span.

These voluntarily donated life spans cannot be converted into the crystallization of the rules of heaven and earth if the person who donated them has even the slightest unwilling thought.

Fortunately, the amount of immortal stones he obtained this time was sufficient, so the loss of immortal stones and Eternal Night Pills was not worth his regret.

"That's good. I won't have that many immortal stones to use in the future. Come on! Convert them all into crystals of the laws of heaven and earth!"

Lu Qing'an asked Liu Lingxuan to teleport everyone away, and he was the only one left in this space. He set up a formation here to prevent others from peeping, and then pressed the button to generate the crystal of the rules of heaven and earth.

The next moment, purple lightning flashed in the huge ball of light containing a large amount of voluntary lifespan, and then all the lifespans turned into pure energy of the rules of heaven and earth, and were finally stored in pieces of crystals of the rules of heaven and earth.

Lu Qing'an put away this batch of crystals of the rules of heaven and earth and continued his operations.

This time, it’s his turn to input his own lifespan!

He input his lifespan into the ball of light without saying much. He only left a small amount of lifespan for himself and transferred the rest into the ball of light.

In the blink of an eye, more lifespan than the lifespan input by more than 2,000 people just now appeared in front of Lu Qing'an.

Lu Qing'an raised the corner of his mouth. The crystal of the rules of heaven and earth converted this time will be able to break his record!

"Convert!"

The sound of crystals colliding echoed everywhere.

A large number of crystals of the rules of heaven and earth appeared.

Lu Qing'an quickly collected these crystals of the rules of heaven and earth and placed them among other crystals of the rules of heaven and earth.

Soon, all the crystals of the rules of heaven and earth gathered together.

He began to count carefully.

The final number made him very satisfied!

"This is enough for me to cultivate the Sky Locking Law!"

The number of crystals of the rules of heaven and earth harvested this time is a full 160,000!!!

That’s right!

One hundred and sixty thousand!

Adding the 20,000 crystals of the rules of heaven and earth that he had found in the spatial field not long ago, there were a total of 180,000 crystals of the rules of heaven and earth!!!

This was a huge amount of wealth he had never had before.

If he told the red-haired middle-aged man this number, he would definitely be dumbfounded.

"I'll keep 130,000 for myself, which should be enough to cultivate the Sky Locking Law. As for the remaining 50,000 Heaven and Earth Rule Crystals, I'll give some to Yongfu to improve his luck. Some to Qingying, as she should have used up all the Heaven and Earth Rule Crystals from last time. I'll also give some to Xiao Heizi and the others."

Thinking of this, he suddenly felt that the number of crystals of the rules of heaven and earth he obtained this time was still a little too little.

"Nowadays, more and more people have successfully cultivated the Saint Realm skills. I have to give a little to everyone. Otherwise, if I only give to a few people, the others will definitely feel uncomfortable. After that, I still have to continue working hard to earn the Crystals of the Rules of Heaven and Earth..."

Lu Qing'an took a deep breath.

His way of earning crystals of the rules of heaven and earth has now become more fixed.

Repeat these steps in the future.

Cultivate elixirs, earn elixirs, and burn elixirs.

Kill the devil.

Earn immortal stones to produce Eternal Night Pills, and cultivate powerful Taoist Saints to transform them into crystals of the rules of heaven and earth.

Another thing is to continue to let Murong Yingxue and Qinglong research ways to cultivate holy medicine.

He brought all the crystals of the rules of heaven and earth and returned to the Shijin Dragon Court through teleportation.

He first found Liu Lingxuan, who had just helped him with something not long ago.

"Uncle Master, these one thousand crystals of the rules of heaven and earth are for you. You did a great job this time." Lu Qing'an directly took out a thousand crystals of the rules of heaven and earth and handed them to Liu Lingxuan.

Seeing so many crystals of the rules of heaven and earth, Liu Lingxuan quickly said, "Give me all of these? That's not good! How about I just take a few hundred, and give the rest to Weiwei. She probably needs more crystals of the rules of heaven and earth right now!"

Du Weiwei had already been able to practice the Saint Realm techniques and had received a powerful inheritance. After possessing the crystallization of the rules of heaven and earth, she would soon be able to practice the laws.

Lu Qingan smiled and said, "I will send her some money later, so you don't have to be polite. This is what you deserve."

Liu Lingxuan still didn't accept it after hearing this. She said weakly, "But you said last time that you would reward me. I thought I was the one who proposed the reward..."

Lu Qingan was a little afraid to hear this, and now he heard it, he felt a little embarrassed: "Then, what reward do you want?"

Well, you can't deny what you said.

Liu Lingxuan tucked her long hair behind her ears and said, "Can you please stop calling me uncle from now on? Just call me Lingxuan."
