Before this, spiritual sources have always been Zhang Qifan's main source of energy and his greatest reliance. When his civilization level was still at level 2, he used this energy that had only begun to popularize the sixth civilization, which was like opening a super plug-in for him.

Its effect is even more powerful than using internal combustion engines in the Stone Age and launching nuclear fusion in the 20th century. It is also because the spiritual source exempted him from his concerns about energy, so that his civilization could develop so quickly.

If there is no spiritual source, it is absolutely impossible for him to activate his soul strength to two million points without spending 8,000 years.

As the spiritual source that is the biggest driving force for Zhang Qifan's power development, it is actually insufficient? That is really a big problem of life and death.

Some people say that if the spiritual source is gone, use energy blocks, how can it endanger life and death?

Just as there were no air conditioners in ancient times, the trees could cool down. Now if there were no air conditioners, it would heat up to death by 99% of humans.

The life-saving systems of tens of billions of creatures are all provided by spiritual sources, and they cannot be supplied if they are replaced by energy blocks or even antimatter. If there is a problem with the life-saving system, these tens of billions of creatures will be dead.

"It's not that it's not enough." Dong An flew over and continued: "In order to avoid sitting in a waste of time, we started to cultivate spiritual sources in a planned way at the hidden place, but the production speed has not been increased. The expenditure and income of our reserved spiritual sources are in a loss state. Although there will be no problem in a short period of time, this state is too dangerous, so we began to plan to reduce some unnecessary losses."

Dong An's tone was a little awkward and resentful. The one in front of him was her son. What's the point of making a report? But she couldn't treat it with her previous mentality.

The more you know, you will know what Zhang Qifan is now. The greatest monarch in human history. He only commands tens of millions of square kilometers. Even the chairman of the current human federation will only rule a mere two thousand light-year range.

But now Zhang Qifan is the overlord of the entire Milky Way, an existence at the same level as the Queen of Star Crystal and the King of Titans. His random thought can turn hundreds of galaxies into nothingness, and a command can influence the fate of tens of billions of living beings.

Such a powerful existence, neither Zhang Yuanshan nor Dong An could treat him with the same mentality as before. It would be fine if everyone was still a human being, but since he changed his life form, Dong An understood that blood relationship is no longer a factor in maintaining their relationship.

The reserves of spiritual sources are now managed by Dong An. In order to prevent the decline in inventory, before production is increased, spiritual sources' expenditures will be greatly reduced. For example, those disposable consumptions in the past have basically been cancelled, and even the cultivation of super life has been temporarily stopped.

Zhang Qifan did not pay attention to Dong An's embarrassment, and instead asked: "How is the production situation of Lingyuan?"

How did the spiritual source come from? It was extracted from Xilan. How did the Xilan come from? It was soaked from the breath of death. The method of producing spiritual source is very simple. Increase the concentration of the breath of death in a closed space and throw the soil into it.

Most of these spiritual sources in Zhang Qifan's hands were harvested from the water source galaxy and the death star. A small number were produced in the hidden place, but the history of the hidden place was very short after all, and the output was insignificant.

Now that there is a stable rear, the survival of spiritual sources can be greatly improved.

The answer to Zhang Qifan was Rose: "We are now away from the cultivation ground in one of the small hills. All the soil is piled up there, and it is stipulated that after all organisms die, they need to be buried in the cultivation grounds in a concentrated manner. However, in recent years, our life technology has improved rapidly, and the biological mortality rate has been greatly reduced. Therefore, the pollution progress of the cultivation grounds is not fast, and it is temporarily impossible to produce qualified spiritual sources in a short period of time."

The breath of death is released by dead creatures. The hundreds or hundreds of billions of creatures under Zhang Qifan's command actually have a large number of normal deaths every day. However, these years are the period of civilization explosion, and life technology is changing with each passing day, and it is changing at a dazzling speed.

The average life expectancy last week may be only 250 years old, but this week it has increased to 251. During this period of great explosion, the potential of life expectancy has not been fully tapped, so the number of natural deaths dropped sharply to only one percent.

In a few hundred years, I guess I will not be able to fill the location of the cultivation ground.

It is not without anyone to massacre a group of human slaves or low-education creatures in batches, but they were rejected by the first group of people under Zhang Qifan who followed him. Whether it was Antonio, Schneider, or Huang Chunjiang, they still maintained a simple view of species and could not do such cruel things.

However, their ideas made many people not understand, including the later group of human slaves.

Killing chickens and dogs so happily, and even peeling and removing bones to stew into broth, now killing some human slaves and low-education creatures feel cruel? If human slaves are the same species and are wise, then humans treat orangutans as cruel, can they not be wise?

Although I couldn't understand it, Antonio and others insisted on their opinions, and the proposal was finally rejected.

Some people have also proposed to use cloned creatures instead, but the breath of death is of great importance to the level of intelligence, lifespan, and strength of will. The effect of cloned creatures is very poor. In addition to not producing much death aura, it also occupied a large amount of space, and finally left it alone.

After hearing Rose's words, Zhang Qifan looked at her in amazement: "You won't be using normal dead bodies to decontaminate them, right?"

Zhang Qifan's words made most humans reincarnated hearts stumble. If they don't need corpses that die normally, should they use "abnormal" to die? Could it be that Zhang Qifan would not support the massacre of a group of human slaves?

Rose was stunned for a moment, and without thinking too much, he responded: "Yes."

She felt that Zhang Qifan also supported the massacre of creatures to accelerate the destruction. She did not have much of her own opinion on this. As a congenital immortal creature, her concept of death is not much different from plastic tolerance, and she would not have any sympathy for the race of life. So she had no objection whether it was massacred or not.

However, her response made Zhang Qifan shake her head in disappointment, which made her feel nervous. She may not care about the life and death of the race of life, but she cannot ignore Zhang Qifan’s view of her. Did she do something wrong?

When dealing with this Death Star has been following his subordinates, Zhang Qifan couldn't do it too harshly and asked in a heuristic manner: "What species is the largest in our place?"

"Humanity." Luo Si responded without thinking. There were tens of billions of humans migrated from the Panlong Star Domain alone, and the number of human slaves sent by Yunxing One later was close to tens of billions of humans.

Not only Rose thinks this way, but the rest of the people also think this way.

Zhang Qifan shook his head: "Call all the undead creatures and come with me." (To be continued)
