Coming to the underworld to find a way to resurrect An Lingxue is Chen Zheng's main purpose, as for Li Hao's purpose, Chen Zheng doesn't care.

Li Hao was also refreshed, took out a jade slip, carved the method of cultivating the battle seal into it, and handed it to Chen Zheng.

Chen Zheng didn't believe Li Hao, of course, he read the content in it for the first time.

The most important way, or the only way, to open the War Seal is to provide energy to the War Seal, an extremely large amount of energy.

At the very least, it has to be the level of the Immortal Emperor, that is, the extreme of the human spirit realm, to be able to open the battle seal with its own strength, and it will inevitably not be able to open it completely, because in the past, those who could fully open the power of the war seal, there are legends that those who remain are the ancient immortal monarchs, that is, the masters of the Dixiong realm.

In this way, you can imagine how huge the energy required, unless you have the Five Elements Divine Power, like Wang Jie, you can have as much immortal qi as you need to support the opening of the battle seal.

If you don't have the Five Elements Divine Power, you can only find something with huge energy, such as a Divine Source Mushroom.

However, Divine Source Mushrooms are extremely rare, and it is very unreliable to specifically look for Divine Source Mushrooms, so in the final analysis, they still have to be strong and have more energy.

However, Li Hao's jade slip mentions a thing called boundary force, saying that the energy of this kind of thing is higher than the mass of any energy, and it can be absorbed at will, as long as you know how to absorb it.

As for the extent to which it can be opened, each battle seal is different, and you need to comprehend it yourself.

"What exactly is the boundary force?" The jade slip didn't explain much about the boundary force, and Chen Zheng didn't want to absorb something unclear.

Li Hao said with a smile: "Are you still afraid that I will calculate? Let's put it this way, you should know the origin of heaven and earth, the origin of the three transformations, and the regeneration of heaven and earth, then you should know that the original six worlds are one, there is heaven and earth, just like a box, wrapped in endless void, and there is no so-called existence of the six worlds, therefore, the way of heaven is also called the heaven above nothing, the beginning of heaven and earth, there is no void above the sky." Then, heaven and earth are divided into five layers, the middle layer, there are four types of monks of immortals, demons and Buddhas, and there are eight worlds of heaven and earth in the future, and then later, the demon Buddha was destroyed, which is now the six worlds. But since the beginning of the boundary, in fact, it has always been the Five Realms, and the immortals, demons, Buddhas and demons are actually in one realm, in other words, the descendants have not created the realm, and the realm has not changed from the beginning when it was created to the present. Who created the realm? Why did no one in later generations acquire the power of the realm? This has become a mystery, but in fact, there are many research circles in later generations who have studied the energy that forms the realm and called it the boundary force, in fact, you are not too unfamiliar with the boundary force. ”

"The Boundary Wall?"

"That's right, except for the two realms of immortals and demons, the six realms are all wrapped in the boundary wall, and there is no saying that they can fly directly to the other realm, that is to say, originally the heaven and earth were in a box, and someone separated them from each other inside this box, and it became our current world. Layering heaven and earth and condensing the power of the boundary wall is the boundary force. In this way, you should understand that I didn't calculate you, but if I want to make it clear about the specifics of the boundary power, I can't do it, after all, it is a lost power, and no one has obtained it for thousands of years, and to the greatest extent, it is just to absorb a little to use it. ”

Chen Zheng nodded, he could indeed dispel his suspicions about Li Hao, so he didn't ask any more questions, turned around and flew away.

Looking at Chen Zhengfei's figure, the corners of Li Hao's mouth raised an evil smile, and then he chuckled twice before turning around and flying away, parting ways with Chen Zheng.

The world of the underworld is actually no different from other worlds, except that the sky is clearer, like the sea water, which makes people look very comfortable, even the sun is not dazzling, the light is very integrated, even if you look directly, it is like looking at a bright orb.

Chen Zheng has no destination at the moment, so he has not teleported, and if he wants to find a way to resurrect An Lingxue, it is actually very clear that he wants to find the Hades. Chen Zheng could also think that with the ability of the Hades King, he would definitely be able to count Chen Zheng's arrival, however, the Hades King was the master of the First Realm, and even among the powers of the Six Realms, he was also one of the best existences, would he personally come to Chen Zheng and help Chen Zheng?

Chen Zheng didn't dare to have extravagant hopes, only by finding a way to meet the Hades King by himself, and he had to show his respect, so that the Hades King would be willing to help resurrect An Lingxue.

If you are looking for Hades by yourself, you must at least find a place where there are people, and ask how the Hades is doing in the underworld, and there is a direction before you can go on.

I don't know where Li Hao teleported to Chen Zheng, there are mountains as far as the eye can see, of course, there are no people, Chen Zheng flew for most of the day, until sunset in the West Mountain, I saw a market on the edge of the mountains.

"Huh?" Looking at the past, the market is not much different from that of mortals, a long street is full of liquor shops and shops, and people come and go quite prosperously, but, under perception, the aura exuded by this market is extremely powerful, it can be imagined that the people walking around there are monks, and the strength will not be too low, at least above the level of the Golden Immortal.

Chen Zheng was flying over, but he saw that the people walking around the market suddenly stopped strangely, and then looked up at Chen Zheng, which made Chen Zheng very puzzled, didn't he say that with the Dark Pearl, he would not be considered a person from the outside world?

Chen Zheng subconsciously looked at himself, under the influence of the Immortal Pearl, he was glowing with a faint brilliance at the moment, like the white soft light of the Night Pearl, which did not look ghostly, but had a sense of sacredness.

Looking at the people in the market again, as the sun sets, they also have this kind of divine light on their bodies, which is exactly the same as Chen Zheng's body, so look at it, Chen Zheng is indeed no different from a spirit body, why do they look at Chen Zheng?

No matter what, Chen Zheng still restrained his breath, but he was vigilant in his heart, although he didn't feel any strong people in the crowd in the market, but it may not be that no one restrained his breath, in short, it is better to be careful.

"Awesome!"

"Guts!"

"It's true that newborn calves are not afraid of tigers. ”

"This guy is brain-pumping. ”

"I think I dare to fly in the Eternal Forest. ”

There was a lot of discussion in the market, and the discussion naturally fell into Chen Zheng's ears, which made Chen Zheng understand that it was not that he was different from this spirit, but because of the so-called immortal forest below, and he didn't know what was wrong with flying in the immortal forest, anyway, Chen Zheng didn't feel anything, so he ignored it, and asked someone for a while.

fell to the ground, and a few people stepped forward to talk to Chen: "Dude, you are really fateful." ”

"That's it, last time there was a ghost king who didn't know why, and he flew on the Eternal Forest in a hurry, and he was killed in less than half an hour, I see that you have been flying all the way for a lot of time. ”

Chen Zheng looked at the three people who accosted him, two men spoke, and a woman looked at herself secretly in silence, and thinking that she had to find someone to ask about things anyway, these three people sent them to the door, just to make friends with them, so he smiled and said: "I have been on my body since I was a child, and I don't know how dangerous it is to fly in the Immortal Forest, the three of them look very enthusiastic, why don't I treat them, and the three of them will tell me about the outside world, can you?"

"Okay, anyway, we're resting and we're about to eat, so you're in for a treat. ”
