In addition, cultivation is a way to achieve immortality, but not everyone can achieve immortality. Generally, those who do not have cultivation techniques will die even if they are in the foundation-building period no matter how talented they are. If they live to be one or two hundred years old, if human life is extended,

It is of great benefit to the progress of the times.

To put it simply, a group of scientists can no longer continue their research when they are eighty years old, but the knowledge they have learned in this life cannot be used for a longer period of time. They can only write the knowledge they have learned in books for the next generation, but the next generation will learn

By the time he finished his knowledge, he was already in his seventies and eighties.

As age increases, the cycle of knowledge utilization can be lengthened, and technological progress will naturally become apparent.

…

In the training ground, a blue flame was slowly shrinking, and Yang Xin and others were flying in mid-air to look at the situation above.

"I wonder how Jiaojiao will swallow it, this elemental fire that transforms into demons." Yang Xin said to himself worriedly.

"There shouldn't be any problem. The fire demon was swallowed voluntarily. It should protect Jiaojiao and not take risks like you did." Yang Yue said.

The flame below is getting smaller and smaller, and finally it is so small that it becomes a burning person. Finally, the fire disappears, revealing only a naked girl. This girl is really delicate. Jiaojiao is still concentrating with her eyes closed. She needs

Compress the flames in your Dantian.

In the blink of an eye, everyone had flown to the ground. Jiaojiao took a deep breath and then opened her eyes.

"Ah..." Shen Jiaojiao felt very cool for the first time, and then she realized that she was naked. Zhang Ya quickly added some clothes to her.

"How's it going?" Zhang Ya didn't understand this, so she asked worriedly.

"Sister, don't worry, there is no problem at all."

Shen Jiaojiao's purple seal technique is no joke, it can suppress elemental fire. Zhang Ya breathed a sigh of relief and nodded, but she was also worried about herself. Now she is also one of the 70% of people in the world who cannot cultivate.

One of them. She just thought about it, but didn't show it to worry anyone.

Shen Jiaojiao stretched out her delicate jade hands, and with a thought, a cluster of blue flames floated on the palm of her hand.

The flames were so blue that they looked like flames under the sea. People around them couldn't feel the heat at all. If Yang Xin's flames were exposed, they would be extremely hot.

Shen Jiaojiao was now relieved that her purple vitality had completely turned into dark blue, and others had no way of knowing what the original vitality was.

Seeing that Jiaojiao was fine, everyone dispersed and started their own training. Yang Xin had already trained the girls with the close-up magic that Qiankun borrowed, but the progress and power were still lacking.

.

"Xiao Huaxin, shall we practice together? The sisters have all returned to their own practice rooms." Shen Jiaojiao saw Yang Xin meditating and asked.

"Haha, I'm worried about the teacher. She must be in the same mood as those who can't cultivate. How can I say that it's not difficult to cultivate is a big problem, and there is no peace outside. Some people who can't cultivate even disrupt society.

Order, there are many people seeking wealth and murder every day, hey..."

Although Yang Xin is a killer, he feels sad when he sees so many things on the news every day. These are all caused by him. Is this decision to let the earth enter the era of cultivation early? Is this decision wrong or right? Yang Xin

I also have some contradictions.

"Isn't there a lot of sacrifice in the era of change? This law has appeared a long time ago, there is no need to think too much." Shen Jiaojiao shook her head, her heart is naturally made of flesh, for these she I also feel helpless.

"Well. This is the law, the law of survival of the universe, hey, that's fine! By the way, now that our development has been stabilized, and nearly one-fifth of the celestial beings have been explored, I think it's time to find a method of cultivation. Let the teacher also practice cultivation like us."

"I understand how you feel. I learned from the fire demon that there are ways for mortals to cultivate themselves." Shen Jiaojiao saw that Yang Xin was so worried and said.

"Are you serious? Come on, tell me." Yang Xin asked with some surprise.

"You can't cultivate, as long as it's related to the soul. The soul is one of the main sources of the formation of the soul in the future. Without the spiritual root in the soul, you can't cultivate. So if we can get the soul washing spring in the underworld, we can There is a chance to change the soul." Shen Jiaojiao said.

"Soul washing spring? Must it only exist in the underworld?" Yang Xin was a little surprised. He finally found a way, but this method is a bit difficult, right?

"At present, I have only heard that there is one in the underworld, but there are many ghost cultivators in the underworld. It will be very difficult for us to go in and find the soul washing spring, and the method of opening the two planes is also too difficult. ." Shen Jiaojiao said helplessly.

"You mean you have a way to open the two planes?" Yang Xin originally thought that he could open them only by finding the ghost seal, but how to find the ghost seal? So this method is really slim.

"Yes, yes... but it's really risky. The ghost general you came into contact with last time has already explained it all. I think my sister doesn't want you to take this risk." Shen Jiaojiao shook her head, originally she was I didn't want to tell Yang Xin, but I felt that he would find out sooner or later if I kept it from him, so I told him anyway.

"This is my responsibility. I promised her. She doesn't want me to take risks, but I don't want her to grow old or sacrifice for me. Really, Jiaojiao, I know you have a way. Just tell me. , I must get the Soul Cleansing Spring." Yang Xin said with some excitement.

"Okay, little Hua Xin, I will accompany you, because without me, it will be difficult for you to complete this mission. Prepare all kinds of combat equipment. We can enter the underworld and fight for a while."

Shen Jiaojiao smiled faintly. She knew that Yang Xin would make such a decision, so she did not refuse. If she had done so at the beginning, she would have refused. It was an absolutely rational choice.

"Thank you, Jiaojiao, you have to protect yourself at all times, do you understand?" Yang Xin nodded, knowing that he could not live without Jiaojiao, and Jiaojiao would not let herself go to that world alone. go.

"Well, then let's take high technology to the underworld and see their world! Hehe, maybe there will be other discoveries." Shen Jiaojiao said with a smile. Now that she has made a decision, she must not look back and worry about it. It is of no use, so Jiaojiao is now facing it very actively.

Just do what you say and leave the research on opening the two planes to Zuo Xianhui. She has already been studying ghost seals before. Although ghost seals are products of the universe, they are not unobtainable.

To put it simply, it is a super collider with a combined function. Of course, its properties are different from those of a collider. One is a product of the era of cultivation and the other is a high-end technology product.

It is expected to take half a month, and I have already been researching it for half a year, so it adds up to a long period of research. Later, when I understood the rules, I studied the structure of the ghost seal more deeply.

Then she participated in the design of Xianji gas station. It can be said that Zuo Xianhui is now a very powerful cultivation scientist, so she has her scientific research team. Now that Yang Xin's plan is in place, they will naturally work hard to tackle the problem.

.

In addition, Jiaojiao has prepared some necessary high-tech weapons. Among them, Jiaojiao has an even more terrifying idea, which is to bring in the solid space and put several airships inside, as well as a certain amount of supplies.

Once this experiment is successful, it means that they can bring a large amount of things to that world, and there will definitely be no shortage of supplies.

A week later at midnight.

Everyone is busy preparing for this operation, and Yang Xin is no exception. He is strengthening the cultivation of Qiankun Leverage every day. Now he can exert two levels of strength, and the "shield" can be used to

The third level of effect has been achieved, and the time has been extended to one and a half hours.

His training only requires physical exertion, but Zuo Xianhui and Jiaojiao are different. It consumes mental power. Jiaojiao's ideas are studied with other scientific groups. Most of the scientists left here are

d organization, so the research on solid space has reached a certain level, as long as it is a matter of time.

Yang Xin had already visited Jiaojiao at around seven o'clock in the evening. It was hard to see her, and she felt a little sad. However, the solution was imminent, so he could only work hard for her and repay her in the future. Now he was going to go

Look at Zuo Xianhui, there has been no movement over there for a week.

When he arrived at the laboratory, Yang Xin saw many scientists working in shifts discussing drawings, while Zuo Xianhui was so tired that she fell asleep on a chair without taking off her experimental glasses.

Some scientists would give a solemn military salute when Yang Xin entered, but Yang Xin waved his hand to stop him and came to the side of Zuo Xianhui.

"How many days has she not slept?" Yang Xin asked the scientists around him calmly. These scientists all respected Zuo Xianhui because she was the first and greatest cultivation scientist in history.

"Colonel, Captain Zuo Xianhui didn't sleep the night you assigned the mission..." As soon as he finished speaking, Yang Xin made a silent movement.

"Go ahead, thank you for your efforts, and I will reward you accordingly." Yang Xinchong said to them calmly. Two-thirds of those scientists were Chinese, so they all showed modest expressions.

Yang Xin picked up Zuo Xianhui and rushed to the lounge, where he put Zuo Xianhui and lay down on the bed.

She had just broken through the foundation-building stage. Although she could go without eating or sleeping for a long time, that was during cultivation, and when they were working at such a high frequency, the energy consumption was very serious.

Yang Xin held Zuo Xianhui's little hands, those slender little hands, and sat beside her bed. Yang Xin was really grateful to her in his heart. His friendship with her only started with Wang Yan. If he said he loved her,

, maybe it’s because of Wang Yan’s influence, but she never said it out loud.
