The beginning of the prehistoric era suppresses and kills the traversers

"Just now I sensed a magical power suddenly appearing in the tunnel echoing my origin, it seems to be the foundation of my enlightenment!"

"I don't know if I can allow my disciples to practice in the tunnel?"

As soon as he heard the words of the Holy Mother of the Yellow Spirit, Tongtian was delighted,

Originally, I was worried that after they left Xuanli World, the power of the tunnel of reincarnation would be left unattended, and there might be some problems, but they never expected that the Holy Mother of the Yellow Spirit would come to their door on their own initiative!

Empress Houtu has no objections, and Tongtian is naturally more willing!

"Since you are predestined with this way, then I will confer on you the title of the Holy Mother of the Yellow Spirit, and take charge of reincarnation!"

"The power of reincarnation is mysterious and profound, you need to study it carefully and don't be lazy!"

"If there is a power to communicate with you in the future, don't panic, it is the cause and effect of the reincarnation of the prehistoric world!"

"Your duty is to guard the reincarnation, absolutely not allowing anyone to damage the power of reincarnation, understand?"

With the approval of Tongtian and the others, they can practice in the tunnel,

The Holy Mother of the Yellow Spirit was naturally very happy, no matter what request she had, she agreed to it one by one!

Before Tongtian and the others left, it would be great if they could just find a candidate to guard the tunnel!

Empress Houtu briefly explained to the Holy Mother of Huangling some things to pay attention to in practice,

The main thing is to control the power of reincarnation, and then he and Tongtian returned to the prehistoric world with Wang Ruo and their fleet in the human world!

After several technological transformations, the current fleet space jumping technology is far more powerful than some monks in the Primordial Realm!

In just three months, the fleet has returned to the mortal world after one hundred and eight space jumps!

Even if it was the departure of Tongtian who had not yet broken through the Dao of Heaven, it took two full months for this road.

At that time, Tongtian was already in the realm of Hunyuan Realm Nine Heavens Great Perfection!

After returning to Honghuang, Tongtian naturally arranged the fleet of the mortal world to help Empress Houtu send the survivors of the Wu clan who had been hiding in the tunnel to the Xuanli world immediately!

Anyway, the mining fleet has been going back and forth,

Naturally, there is no problem in sending a few more people!

After Tongtian arranged these things, he did not return to the world of cultivating immortals, but went straight to the direction of the scientific research institute!

Even after hundreds of years,

But when Tongtian appeared at the entrance of the scientific research institute, there were still service personnel who immediately came forward to receive him, and directly took the most convenient passage to enter!

All this is because Xu Huilin has never left!

Today's biotechnology in the mortal world is powerful enough to extend the lifespan of people to 500 years, but the Science and Technology Alliance did not allow this technology to be put into use!

Because the extension of human life span will only increase the population pressure in the mortal world,

Therefore, the life expectancy of ordinary people is still maintained at about two hundred years old, even the rich and government officials are no exception!

The abuse of lifespan may not be a big deal in the world of cultivating immortals.

Because the monk itself is doomed, the life expectancy you want will be obtained entirely by your own cultivation, or it will be obtained by robbing the world!

Even so, it is possible to die from various disasters!

But the mortal world has the power to restrain mortals, and there is no interference from the disaster of destiny. If life is extended freely, it will be a population disaster!

And Xu Huilin, a monk in the realm of Daluo Jinxian, still exists in the human world,

Her long life span once aroused the dissatisfaction of the Science and Technology Alliance. Everyone thought that she must have used some genetic medicine to prolong her life!

Until Xu Huilin personally showed them what a monk is,

That's what makes most people shut up!

Following the guidance, Tongtian quickly came to the familiar office, just in time to see Xu Huilin waiting for him here with a smile on her face.

"Uncle Tongtian, you are finally back!"

"This office has always been decorated as it should have been when you were there, and it has never changed."

"But it's been hundreds of years. People in the institute who don't know you have questioned me about keeping such an office."

When she said these words, Xu Huilin was obviously depressed,

In fact, she has always wanted to follow Tongtian, but she has practiced for thousands of years, but she is only in the realm of Daluo Jinxian!

Compared with those disciples who intercepted the teaching, she was far inferior!

Especially when the enemy of Nie Mietian called last time, she couldn't do anything except hide here and control Skynet!

If you want to follow Tongtian's mind, you can only keep it in your heart!

Tong Tian could sense something, but he chose to turn a blind eye to this thought. It didn't seem to be half-contaminated, but mainly for Xu Huilin's consideration!

There are too many merits and virtues in him, and there are too many karma involved!

Once Xu Huilin had any contact with him, she couldn't bear it at all!

"Thank you for your hard work, I will definitely praise you in front of your master!"

"I came here this time to find out how the technology of the prehistoric mortal world is developing today, and how the power of the defense line compares to when we were dealing with Nie Mie Tian back then?"

Hearing that Tongtian opened the topic, Xu Huilin naturally put away her thoughts in a hurry,

"Uncle, the progress of science and technology is different from the world of cultivating immortals!"

"The more advanced the technology, the more the progress is beyond the era. The development of the past 300 years has far surpassed the development of the past 3000 years!"

"Quantum weapons have been completely banned, and now the photon energy we have developed is more concealed and more powerful!"

"The preliminary test has surpassed the strongest quantum energy cannon of the year, and has successfully built six lines of defense!"

"That's not counting, our space technology has already made breakthroughs!"

"Maybe you haven't noticed that there is a layer of space around the prehistoric world. As long as we open it, the enemy will never be able to get close to the prehistoric world!"

"My master has already helped us test it!"

Chapter 643 Powerful technological power!

"Oh? Empress Nuwa personally tested it?"
