After listening to grandma's explanation, Li Yu finally understood what kind of existence the so-called underground legion was.

"Grandma, where are my parents? Where are they now?"

Li Yu asked.

His parents' situation is the most concerned issue.

"Your parents..."

Wang Guizhi's face showed a sad look, "They accidentally lost the troops during an operation, and their whereabouts are still unknown..."

"That is, they are missing?"

Li Yu frowned slightly.

"Well, that's what I can say!"

Wang Guizhi nodded, "In recent years, the people of the Dark Dragon Legion have been helping us find your parents, but there has been no news. However, without news, it is actually a good news. At least, this shows that they still have a little chance of living!"

"Grandma, how do you go to that underground world?"

Li Yu asked anxiously.

Since his parents may still be alive, he naturally must find a way to find them.

"Good grandson, what do you want to do? Could it be that you still want to find them in the underground world? If that's the case, you'd better not think about it! Because the underground world is far more dangerous than you imagined! It's another world that is completely different from our surface world! It's full of killings and cruel struggles, and it's definitely not a place that ordinary people can go! Even your grandmother, I, don't dare to go to that underground world easily now!"

Wang Guizhi smiled bitterly.

"Oh? Is that so? Grandma, can you tell me how dangerous it is?"

Li Yu smiled indifferently.

You know, he is not an ordinary person either.

It is not certain for ordinary people to be very dangerous.

Of course, there is no harm in learning more about the underground world before going.

"Okay, good grandson, I will tell you a little about the horror of the underground world!"

Wang Guizhi nodded, "In the underground world, there are not only various powerful demons, but also many different legions. The Dark Dragon Legion is just a legion of our Jiuzhou Kingdom. There are many legions that are not friendly and even hostile to us! The most important thing is that there is almost no order and law there, and they are all spoken with fists! Many people in the underground world actually did not die at the hands of the demons, but were killed by other humans! In short, the dangers there are hard to guard against, and even those with strong strength dare not walk around at will!"

"Grandma, how strong are those demons? In addition, are there any distinction between humans and strength? How do other people compare with you?"

Li Yu asked.

"The strength of demons and humans is different from each other!"

Wang Guizhi explained, "In the underground world, the way to divide strength is very simple. Whether it is a demon or a human, they are divided into level one, level two, level three, etc. according to their strength! Your grandma, I am now a second-level warrior! I can only be considered a medium-level, or even a medium-level, because I may not have contacted some of the top strong people yet! Many people are stronger than me! Your parents are better than me. They were both level three humans at that time, and they all served as a team leader in the legion, and there are more than a dozen second-level humans under their command! No matter how strong they are, they are level four captains and level five commanders! As for whether there are level six or even level six or above, I am not sure!"

"That's how..."

Li Yu pondered.

The strength that grandma just showed is probably equivalent to the silver special police.

If the second-level humans correspond to the silver special police, and the first-level humans correspond to the bronze special police.

Then the third-level human may be the corresponding golden special police!

That is his current strength!

From this point of view, he is only at a medium level in the underground world.

If it is past now, it will be more dangerous!

But since this matter is related to his parents, it is natural that he has no idea that no matter how dangerous it is, he will go and take a look.

"Grandma, are the strengths of those demons born? In addition, how do humans become stronger?"

Li Yu said curiously.

"The power of the demons is partly born, but they can also be improved by devouring human souls after birth!"

Wang Guizhi explained, "As for humans... it is improved by devouring the flesh and blood of the demons and exercising! The human soul is a great tonic for demons, and the flesh and blood of the demons is also a great tonic for humans! The purpose of exercise is mainly to promote digestion and absorption and accelerate the speed of becoming stronger!"

"There is actually such an operation... Exercise? How to exercise? Could it be that there are other exercises?"

Li Yu asked.

"Where are there any martial arts? Do you think this is cultivating immortals?"

Wang Guizhi shook her head and smiled, "The way humans exercise is very simple, it is just ordinary physical exercise, similar to fitness, but the intensity is much greater! Especially when breaking through the shackles between levels, you have to exercise desperately and devour a large number of demonic flesh and blood! In addition, there are some magical treasures in the underground world that can also enhance human strength, such as some thousand-year-old Ganoderma lucidum!"

"That's it...I understand!"

Li Yu nodded.

"Cough! Cough!..."

At this moment, his grandmother Wang Guizhi suddenly covered her mouth with her hands and coughed a few times.

After taking away his hand, blood actually appeared in his palm.

"Grandma, what's wrong with you?"

Li Yu was suddenly shocked.

"Haha, nothing. When I went out for a trip last time, I didn't accept my old age. I secretly went to the underground world and was injured by several demons! Don't worry about me, I'm almost buried in any case. This injury is nothing!"

Wang Guizhi shook her head and smiled.

"Grandma, wait a moment!"

Li Yu said with a serious expression, then stood up and walked towards the kitchen.

I vomited blood, nothing?

With such a serious injury, he naturally would not let it go.

After a while, he came out with a glass of water.

The water in the cup is the water of life he secretly took out.

"Grandma, have a drink of water!"

Li Yu handed the cup to grandma.

"Um!"

Wang Guizhi nodded and then took a sip.

“…”

As soon as he drank it, Wang Guizhi suddenly widened her eyes and looked at the glass of water in her hand in disbelief.

Because the moment she drank this sip of water, the injuries in her body were healed instantly!

Even the strength that had been stagnant for a long time has increased a lot, directly reaching the peak of level 2 human beings!

Judging from this situation, if she finishes drinking this glass of water, she can definitely break through to become a level 3 human!
Chapter completed!
