Ji Zhi didn't look at Hua Er again, but took advantage of the effect of Tianyan to still focus on observing other artificial womes.

There are not many artificial wombs in the reproductive acceleration zone, only ten, of which four are empty, and only six are developing fetuses in artificial wombs.

Although the reproductive acceleration technology is claimed to be a safe and non-dangerous reproductive technology, the babies produced with this technology are no different from normal babies, and you can see your children in advance without waiting for such a long time.

However, it is very surprising that this technology has been snubbed by almost all the inhabitants of the city fortress. No one wants to choose reproductive acceleration technology in order to save that little waiting time, but would rather wait quietly for the fetus in the artificial womb to grow and develop slowly until it finally matures naturally.

In fact, the most widely used reproductive acceleration technology is not in reproductive technology, but in the cultivation of artificial edible meat and the cultivation of exotic animals.

As the inventor of this technology, Ji Zhi himself has always believed that this technology is extremely beneficial to the artificial growth of Bluestar. But for some reason, there is no problem with the technology, and the cultivation of alien embryos is also very smooth, but in the cultivation of human embryos, the mortality rate has always been high, and the proportion of stillbirths is almost as high as forty percent.

Especially in the No. 4 artificial uterus in front of me, the stillbirth rate is as high as 70%. No matter how healthy the implanted embryo was at first, no matter how carefully he cared for the embryo in the artificial womb, the embryo inside always began to slowly weaken after 12 weeks for unknown reasons, and rarely lasted until it was born.

He had carefully checked the operation of the No. 4 artificial uterus countless times, and all the indicators showed that it was normal. He never understood what the reason was, so he could only try to avoid using the No. 4 artificial uterus. However, because the experimental assistant was newly assigned to him in the family, he did not know the particularity of the No. 4 artificial uterus, and mistakenly implanted the newly fertilized embryo. By the time he found out, the embryo had successfully implanted and developed, and it was no longer suitable to move.

It wasn't until today, with the blessing of Tianyan's spell, that he discovered that there was still a special existence such as a "baby ghost" wrapped around the No. 4 artificial womb. He carefully observed the other nine artificial wombs, and found that on the other artificial wombs, although there were also human black shadows, those black shadows were very faint, and almost all of them were incomplete and inhuman. It can't be compared to the "baby ghost" in the artificial womb No. 4 they just saw.

Could it be that the embryos in the No. 4 artificial womb that died halfway were all made by the "baby ghost"? Now that the "baby ghost" has been devoured by the thunder baby, does that mean that the mortality rate of the embryos in the No. 4 artificial womb will not be so high in the future?

Just now, the thunder baby has been devoured many times outside, does it mean that there are actually some mutilated babies and ghosts in those artificial wombs outside? It's just that because those babies and ghosts are some unformed and weak existences, they have not caused the mortality rate of embryos to remain high like the No. 4 artificial uterus?

Think about it from another angle, if Lei Ying can devour all the babies and ghosts, will the embryonic mortality rate in the reproductive acceleration zone also become as low as the mortality rate of ordinary artificial wombs outside......? In the future, the promotion of reproductive acceleration technology will no longer be a problem?

Ji Zhi's gaze scanned back and forth between the No. 4 artificial womb and Lei Ying, with a thoughtful expression.

He also knew a rough idea of Lei Ying's origin, and he didn't know if Jiujiu would be willing to hand over Lei Ying to him if he asked Jiujiu to borrow Lei Ying?

Ji Er lowered his head and waited for a long time, not waiting for the words of his father and eldest brother's reproach. Instead, he heard Hua Yi's voice curiously asking his mother Ling Bing.

"Mother, what's going on with those baby ghosts? Why do they keep wrapping around the artificial womb? Also, why can Lei Ying see those baby ghosts and devour them? What effect does the existence of baby ghosts have on the fetus in the artificial womb?" Hua Zai guessed Ji Zhi's thoughts from his father Ji Zhi's eyes, and took the initiative to ask Ji Zhi a question that he was inconvenient to ask.

In fact, for Hua Yi, who is also obsessed with research, aren't these questions the most concerned in his heart?

"They don't call them baby ghosts, they call them baby spirits!" Ling Bing glared at the fog demon, very helpless about his nonsense.

"Baby spirit, well, this sounds good! it's much better than that baby ghost!" said Hua San.

"Nothing that sounds good or bad, no matter how good it sounds, can't change the fact that it refers to the same creature. Hua Si retorted disappreciatively.

"That's better than a baby ghost! What the hell, what a ghost, it sounds eerie, and it's particularly uncomfortable! Little Seven, Little Eight, do you say?" Hua San was not convinced, and pulled Hua Qi and Hua Eight into the water.

"What's the use of sounding good? Aren't they all gloomy? I think it's more vivid to call a baby ghost!"

The four flowers are on the same as the three bars. Hmph, Hua San is hard-mouthed, don't think he doesn't know, it's obvious that Hua San is afraid of ghosts and doesn't want to hear the word "ghost", so he said that the baby spirit is good, and he is not as good as he wants.

"Little Four, it's against you! Are you good? Deliberately, right? Come on, come on, or let's fight first, whoever wins will speak. It's good to take the opportunity to let you know clearly, which of us is the elder brother!" Hua San was angry, and as soon as he rolled up his sleeves, he was about to fight.

"Come on, who's afraid of whom?" Hua Si was not afraid at all, and as soon as he rolled up his sleeves, he was about to rush up.

The two bulls were facing each other, and they were about to meet.

"Alright! Shut up! You two are going to fight, go outside, don't mess around in my lab!"

Hua Yi was furious, he asked his mother for advice, what are these two coming up to make trouble? With a wave of his hand, two crystalline clouds of ice water fell from the sky and landed accurately on the heads of the two of them, and immediately froze the movements of the two of them like bulls.

"Ah~, cold!"

The ice water showered his head, and it was extremely cold, and Hua San and Hua Si shivered at the same time, and immediately settled down.

"Hehehe! Big brother is mighty!"

Seeing this, Hua 5 and Hua 6 covered their mouths at the same time. Hua Qi and Hua Ba also forced a smile, coughed lightly, and looked elsewhere.

"Mentally retarded!"

The fog demon rolled his eyes and said disdainfully. The sound was not loud or small, but it just made everyone hear it clearly.

"You ......"

Hua 3 and Hua 4 glared angrily at the fog demon, but they dared to be angry and didn't dare to speak. The notoriety of the fog demon's moodiness has long been ingrained in their bone marrow, and to be honest, they really don't dare to provoke him.

"Mother, go on!" Hua Yi glared at Hua San and Hua Si again, warning them not to come out again, and then respectfully pleaded with Ling Bing.

Nodding at Hua Yi, Ling Bing continued:

"What the fog demon said just now is actually right, the infant spirit is actually essentially a kind of energy body. It's just that this kind of energy body is more special, they are incarnated by those dead fetuses. However, not all dead babies can be transformed into infant spirits, only those special fetuses with a strong desire to survive but cannot survive for various reasons, coupled with the influence of some external factors, can be transformed into infant spirits after death. ”

"A special fetus with a strong desire to survive, but unable to survive for various reasons, can be transformed into a baby spirit?" Hua Yi was stunned and repeated softly.

"That's right! Because I can't survive, I have a great deal of resentment, so that my mental power has turned into a shape. This is the nature of infant spirits. In the final analysis, in fact, the infant spirit is essentially a spiritual force. Ling Bing nodded.

"Spiritual power transformation, can an unborn fetus also have spiritual power?" Hua San couldn't help but come up and said in surprise.

"Absolutely. From the moment the fetus's brain is generated, the fetus has its own consciousness. Being conscious, mental power naturally arises. The difference is only in the strength of mental power. Most fetuses have extremely weak mental power and cannot be detected at all. Ling Bing explained.

"That'..... What is the matter with the transformation of spiritual power? Can such a weak spiritual power also transform into a shape? Then an awakened person like us, can't all be transformed with spiritual power?" Hua Si also came up and interjected.

"In principle, it is!" Ling Bing nodded. For example, if a cultivator reaches the Yuan Infant stage, the Yuan Infant is out of the body, which is actually another form of spiritual power incarnation.

"That'...... Then can I also transform my spiritual power? How can I transform into a shape?" Receiving Ling Bing's affirmative answer, Hua Siqiu was pleasantly surprised, and couldn't wait to ask.

"Cut~, it's just you, and you're still mentally transformed, will you talk about it in another hundred years?"

"Why? Mother clearly said that it was true in principle. That means I can also transform my mental power. The fog demon is big, don't bully me!" Hua Si said unconvinced.

"The master said that in principle, it is okay, but he didn't say when it can! With the qualifications of the two boys of Hua Yi and Hua Er, maybe in another thirty or fifty years, they can indeed transform their spiritual power. However, with your qualifications, if you want to transform your spiritual power, you have to cultivate for another hundred years, right? Oh no, maybe a hundred years will be considered as my opinion of you, and maybe you won't have the opportunity to transform your spiritual power in your life. The fog demon sneered and directly gave Hua Si a critical hit.

"You, you...... Mother, the fog demon bullied me a lot!" was hit by this critical blow, Hua Si glared angrily, but when he looked at the fog demon's ill-intentioned eyes, he suddenly felt a void in his heart. With a roll of his eyes, Hua Si suddenly turned his face and complained to Ling Bing aggrievedly.

"Poof~, shame!" Hua San almost squirted and whispered with disdain.

Hua Yi couldn't help but want to touch his forehead, regretting his decision for the first time. He knew that the two of them were so good at mischievous, and he said that he would not tell them the news that his mother was coming. Now the focus of the problem is what is going on with that infant spirit, can't they grasp the key point? He has a hunch that if he can solve the matter of the infant spirit, it will definitely have a great effect on the future population growth of their Blue Star.

"Mother, is it because of this baby spirit that the mortality rate of the fetus in the No. 4 artificial womb is so high?" Because of the mist demon's prank just now, Hua Er was silent for a long time, and he also watched coldly for a long time, naturally understanding where the focus of the eldest brother Hua Yi and his father was, so he suddenly opened his mouth and pulled the topic back.

Suddenly, Hua Yi gave Hua Er an appreciative look.

"Not bad. Although the infant spirit is the spiritual power of those dead fetuses, from the day he appears, it has become a nightmare for all fetuses, and he will forcibly absorb the essence and spirit of the developing fetus, causing the fetus to die in the womb. Ling Bing nodded and said lightly.

Ji Zhi and Hua Yi were taken aback, and glanced at each other at the same time.

Although they had already had a hunch that the little black figure was definitely related to the high mortality rate of the fetus in the No. 4 artificial womb, they were still taken aback after receiving Ling Bing's affirmative answer.

Because of the high mortality rate of the No. 4 artificial uterus, they tried all kinds of detection methods and used all kinds of the latest technology, but they couldn't find out the truth. Of course, they can also replace the No. 4 artificial uterus with a new artificial uterus. However, not long after the new artificial uterus was replaced, there were other artificial uterines with this high fetal mortality rate. Of course, it doesn't have to be number four, it could be number five, number six, number seven......

It's as if it's a spell that can't be shaken off, making the reproductive acceleration technology that should be shining in the dark a chicken rib, which can only be used to breed artificial meat and exotic animal cubs.

"Huhu~"

A slight snoring sound clearly reached the ears of several people, and several people looked at it, but it turned out to be Lei Ying in Ling Bing's arms who fell asleep at some point.

That complete infant spirit is really a great supplement for the thunder baby. After devouring the infant spirit, the thunder infant was no longer able to devour the others. The best way to digest it is to sleep, and in the midst of sleep, the soul power swallowed into its own energy.

"That thunder baby can devour that infant spirit?" Ji Zhi's eyes flashed slightly, and he landed on the infant spirit in Ling Bing's arms, and asked in a deep voice.

Ling Bing's gaze also fell on Lei Ying's body, and after a little hesitation, he nodded.

"That'..... Mother, can you lend me Lei Ying a few days? I want to ......" Hua bit his teeth and glanced at Ji Zhi, and from his eyes, he read the same meaning, "I want to take her to various reproductive centers to have a look." ”

Ling Bing's gaze turned to Hua Yi.

In fact, from the time Ji Zhi asked that question, Ling Bing thought that he wanted to borrow Lei Ying. It's just that I didn't expect Ji Zhi to make this request yet, but Hua Yi mentioned it first. She knew that Hua Yi was a request for Ji Zhi. Whether Ling Bing agrees or not, it will not hurt Ji Zhi's face. Hua Yi is a child who is so smart and careful, and thinks far more than she thinks.

However, she brought Lei Ying here today, originally thinking that she would clear the purpose of the infant spirit in the genital area.

So, she nodded under Hua Yi's expectant gaze.

"Mother, do you agree?" Hua Yixi immediately confirmed to her.

Ling Bing nodded again.

"That'...... Can you lend it to me today?" Hua Yi begged again with a burning gaze.

......
