Chen Hao smiled at the corner of his mouth.

The current sword of life and death is all made of the source root of the mother qi of all things, without any impurities.

Because the Sword of Life and Death is his natal sword, the strength of the Sword of Life and Death is closely related to his cultivation level.

Because he is still only at the peak of the true immortal, the Life and Death Sword is not too strong at the moment.

But as his cultivation level improves, the Sword of Life and Death will become stronger and stronger.

If he becomes the Emperor in the future, he will definitely be the same, not only the sword of life and death will become the first emperor's weapon.

It’s also a pity that Chen Hao did not express his inner thoughts, otherwise it would cause another uproar.

After all, Chen Hao's sword test just now caused a huge noise, and everyone agreed that the Life and Death Sword is now terrifying.

But Chen Hao believes that the Sword of Life and Death is not too powerful now.

If the monks knew about this, wouldn’t they be angry and vomited blood?

"Now we should consider how to remove the remaining source of the mother air of all things."

Chen Hao held the sword of life and death tightly and looked at the source of the mother's qi floating not far away.

He just melted the sword of life and death. Although he consumed a large area of ​​the mother qi source roots of all things, he still had a lot of mother qi source roots of all things.

Chen Hao felt it was necessary to take away the source roots of all things's mother qi, and he could distribute them to the generals of the Heavenly Court in the future, which would also be of great help to him.

"I don't know how much the source of the mother qi of the sword of life and death can accommodate all things."

Chen Hao was excited and nervous, and slowly injected his divine power into the sword of life and death, and began to absorb the source root of the mother qi of all things.

The whole process went smoothly, and the new sword of life and death continued to inhale the source root of the mother qi of all things.

One piece, two pieces, three pieces...

Until a full ten pieces of the mother air source root of all things are inhaled.

The sword of life and death is saturated and cannot absorb more of the source roots of the mother qi of all things.

However, there are still several roots of the mother gas of all things floating outside.

Is there no other way?

Chen Hao thought about it, and a thought flashed through his mind—

The space laws are engraved inside the Sword of Life and Death to further broaden the space of the Sword of Life and Death and increase the ability of the Sword of Life and Death to accommodate.

"I just killed the space-time worm and obtained the origin of space-time Taoism. Now I am just using it, which can be considered as a test of my understanding of the space-time Taoism."

He did what he said, and Chen Hao took action immediately.

Chen Hao sat cross-legged, with the sword of life and death crossing on Chen's knees.

Chen Hao began to recall the laws of time and space that he had memorized before, and then began to think, understand, and understand from the beginning.

A month passed by in a blink of an eye.

Chen Hao basically understood the laws of time and space.

Although it is not very proficient, it can barely make some basic applications.

Pure white light flows from Chen Hao’s fingertips.

Chen Hao used his fingers as his pen and engraved patterns on the sword of life and death.

With the will of heart, Chen Hao was completely immersed in it, and every stroke was natural without any pauses or mistakes.

Another month has passed.

There are light patterns on the sword of the Sword of Life and Death.

Each pattern is composed of hundreds of stripes, with a unique charm.

When Chen Hao activates his divine power, these patterns will light up and bloom gracefully like flowers. While they are beautiful, they will also release powerful suction, sucking all the remaining source roots of the mother air of all things into it.

At this point, all the source of the mother qi of all things was taken away by Chen Hao.

Chen Hao stood up contentedly and left.

"Welcome to the Lord."

Seeing Chen Hao, Youming Kuang quickly knelt down and saluted.

Chen Hao nodded and told the Netherworld Crazy that there was no need to be polite, and then left the Netherworld Mine Cave.

Leng Qingyue, Fairy Winter and Fairy Qinggu came up immediately.

Chen Hao hugged Leng Qingyue in his arms, smiled and greeted Fairy Winter, Qinggu Fairy.

Then Chen Hao came to the crazy old man and took out some of the source roots of the mother's qi from the sword of life and death:

"I hope you will not dislike you if you are caring for me."

The crazy old man stared at the source of the mother's energy in all things. He didn't expect that he would have the chance to get such a legendary divine object in his lifetime.

The crazy old man reached out to touch the source of the mother's qi, and the corners of his eyes gradually became wet.

Chen Hao thought the mad old man was crying with joy, but unexpectedly, the mad old man pushed the source of the mother's energy back to him.

"Senior?" Chen Hao was puzzled.

"You take it back." The crazy old man took a deep breath and calmed down his emotions.

"Senior, do you think it's too little?" Chen Hao asked.

The crazy old man shook his head: "I have already buried half of my body. It is a waste to ask for the source of the mother's energy of all things. Why waste the resources? You should keep it and give it to someone who is more suitable in the future."

Upon hearing this, Chen Hao said with concern: "Senior has a secret disease? Is he a little bit about medical skills, and may help him."

When the crazy old man heard this, he couldn't help but laugh: "I do have a secret disease, but my secret disease cannot be cured by just understanding medical skills."

Hearing this, Chen Hao scratched his head awkwardly: "That...... cough cough cough, senior, I just said that I understand medical skills a little, but I am actually being modest."

The crazy old man was stunned for a moment, then laughed: "Even if you don't understand medical skills, but are proficient in medical skills, so what? It's still impossible to cure my hidden disease."

Speaking of this, the crazy old man smiled bitterly and sighed: "My disease may need to be reborn in the medical ancestors before it can be cured."

Chen Hao was a little surprised. Although his current medical skills are not as good as those of the medical ancestors, they are not too far behind.

Moreover, as a doctor, Chen Hao is most interested in difficult and complicated diseases. When he heard the crazy old man say this, he was curious about what secret disease the crazy old man had!

Therefore, Chen Hao continued to ask: "I know that my talents are ignorant and knowledgeable. It is reasonable for me to believe me but I do not accept the source of the mother's energy given by me. I always ask me to do something to repay my care for me.

Hum? So, it’s better to tell me about the seniors, what disease do you suffer from? You may not be able to cure seniors, but at least you can contribute your strength to seek peace of mind.”

The crazy old man thought about it and thought it made sense, so he nodded.

However, the crazy old man did not tell Chen Hao what he was suffering from, but stretched out his hand and signaled Chen Hao to take his pulse:

"You just said that you are self-righteous when you understand medical skills, which means you have some research on medical skills. I want to see how good your medical skills are."

Chen Hao knew that the crazy old man intended to test his medical skills, so he laughed:

"Young people must do their best to live up to the expectations of your seniors."

After saying that, Chen Hao seized the pulse of the crazy old man and began to take the pulse of the crazy old man.

After a moment, Chen Hao withdrew his hand, which surprised the crazy old man.

But when I thought about it, the crazy old man felt relieved again:

"There is no diagnosis, so I gave up? You are very decisive."

Unexpectedly, Chen Hao shook his head and said:
Chapter completed!
