The violent explosion temporarily blocked Wang An, but only for a moment. Then Wang An broke through the blockage of the explosion, and then he found that the red demon had disappeared.

 “Well, what’s going on?”

Wang An was cautiously on guard. He was worried that the red demon was playing another trick and was preparing to sneak attack him from somewhere. As a result, he turned around and waited for a while to find that the red demon was really gone.

“Is it possible that you were injured and went to the depths of the Blood Valley to heal?”

　　His guess was correct. The red demon really was injured and hid in the Blood Valley to heal.

“Who is he, and what’s going on with that weird skill?”

At this time, the Red Demon was already hiding in the deepest part of the Blood Valley. Where he was, the blood around him was constantly churning. In his injured area, countless blood threads were constantly entangled together, trying to reshape his body. , but Wang An's Wuji Qi was too powerful, and a little bit of it was still stained on his body, and it continued to destroy his body.

This red demon simply cut off part of his body at the shoulder.

　　Then his damaged and mutilated body began to be constantly reshaped. And the extremely destructive Wuji Qi was consumed in this endless blood lake.

The Red Demon looked up into the sky.

 He could feel Wang An's presence, and he was very angry inside at this moment. He couldn't remember the last time he was so seriously injured.

There is no doubt that he wants to kill Wang An, drain his blood, and turn him into pieces, but reason tells him that if he rushes out now, it is very likely that his cultivation will be destroyed. .

After living for hundreds of years, the most powerful ability he has developed is not the Blood Demon Sutra. It is not that being in the blood lake makes him almost immortal. It is his ability to save his life. It is knowing when to fight, what? It's time to hide.

The most rare thing in a person's life is not when to rush forward, but to judge when to take a step back.

There is no shame in hiding to save your life.

 So he endured it and admitted it!

Wang An looked down at the endless lake of blood beneath him. At that moment, he felt as if something was watching him secretly.

The red demon should be hiding in this blood lake that doesn’t know how deep it is.

Hurry down and take a look?

This idea was irresistible as soon as it appeared.

Go and have a look, just in time to see how far you have reached in your cultivation.

His whole body was wrapped in Wuji Qi, and he suddenly rushed into the lake of blood beneath him. There was a bang, and thick blood rose into the sky.

 “Well, he actually came down!?”

Seeing Wang An's behavior, the red demon hiding in the dark was quite surprised.

“Is it a matter of confidence and absolute confidence in one’s own cultivation?”

This blood lake is not an ordinary place. It is made of blood and dirt. After an unknown amount of precipitation and gathering, it has become a filthy and cold place. Ordinary people will immediately rot if they are contaminated with just this bit of blood, and their whole body will turn into a pool of pus and blood and die.

Even the headmaster of Shushan Mountain and the sect leader of Daxue Mountain dare not rush into this blood lake, because this is the absolute home ground of the Red Demon.

 “It’s not that easy to get out once you’re here!”

The red demon controlled the thick and sticky blood in the blood lake to continuously roll towards Wang An.

 Surrounded by turbulent waves, Wang An, enveloped in the realm of Wuji Qi, was like an indestructible diamond. No matter how rough the waves, Wang An was not damaged at all.

However, he could not find any trace of the red demon in the blood lake. Because the interference from the surrounding blood and water was too strong. This is like turning on a search radar under strong electromagnetic interference, and what you see on the screen is a patch of snowflakes.

 “Forget it, get out!”

Knowing that nothing could be done, Wang An rose into the sky and rushed out of the blood lake.

 The blood around him rolled up, trying to keep him, but it was as if the water had fallen on polished stainless steel, leaving no trace at all.

Soon, Wang An came to the sky above the Blood Valley, stopped, and looked down at the Blood Valley at his feet.

 “This is his home court, it is indeed too difficult to kill him here!”

He was looking down at the Blood Valley. In the blood lake at his feet, the Red Demon was also looking up at him.

 “Such a profound cultivation, where did such a person come from?!”

gone,

Wang An turned around and left.

Phew, the red demon hiding in the blood lake secretly breathed a sigh of relief.

 After leaving the Blood Valley, Wang An did not continue to stay in this world, but directly returned to his original world through the space rift.

 The moment he burst out of the crack. Sirens blared in the base, followed by automatic artillery and missiles roaring towards him.

This time Wang An did not dodge them all, but tried to resist some.

The small-caliber automatic cannon hit his infuriating energy and was blocked. The missile landed on it and exploded. Both the shock wave and the flames were blocked by his infuriating energy.

 He left gracefully.

“What’s the situation? It’s obviously been hit, but it’s useless?!”

 The base was dumbfounded after observing the surveillance footage.

 “What is that thing that looks like a dark cloud, is it a monster?”

 Not afraid of guns and missiles.

 This is not a trivial matter, it means that a very scary monster may come from Shushan time. They did not dare to be careless and immediately reported the matter to their superiors.

On the other side, Wang An went straight back to his hometown after leaving here.

 Fighting in two worlds, spanning thousands of miles, the clouds and wind were still calm when I returned, and I didn’t miss dinner.

 “You’re finally back!” Li Xinzhu said with a smile after seeing Wang An.

 “Why, do you miss me?”

“While you were away, the mountain village was quite lively, and many people came to visit you.”

 “Thank you for your hard work these days.”

“It’s not hard work, I also received many gifts, all of which are valuable,” Li Xinzhu said.

 “Where is Xiaohou?”

 “It’s on the mountain.” Li Xinzhu pointed to Dongshan.

“I don’t know what’s going on these days, I’m just alone in the mountains.”

Wang An nodded after hearing this. He is a human being, and some of his practice methods can be passed on to Li Xinzhu, but not to monkeys. Therefore, where the monkey can reach in its final cultivation level and how high it can reach depends mainly on itself.

 Once it reaches a certain level, Wang An won't be able to help it much. Maybe he can give it some help when Wang An's cultivation level is higher.

 “How long do you plan to stay in the village this time?”

"busy?"

 “I want to go out for a walk, there are some things I need to deal with.”

 “Then go.”

 After dinner, while Wang An was chatting with Li Xinzhu, he talked about what Xu Qi had told him about the underworld.

 “Is there really such a place?”

“There is a world in Shushan. It is possible for that kind of place to exist, but it will definitely be somewhat different from the legendary underworld.”

“Hey, are there six realms of reincarnation and eighteen levels of hell?”

 “I don’t know yet, maybe I can only know after going there.” Wang An said calmly.

 “Go down there? The underworld?”

"The monsters there can come, why can't we go there? It's just another world."

“Well, as expected of you, your ideas are different from others.” Li Xinzhu raised his thumb towards Wang An.

After talking about the underworld, Li Xinzhu asked a few questions about spiritual practice, and Wang An answered them all.

Early the next morning, Li Xinzhu left the mountain village to deal with his own affairs. He had been here for a long time. Although he could handle some things on the phone on weekdays, many things still had to be done in person. At first glance, after all, he now has a big family and a big business.

Wang An, who returned to the mountain village, was thinking about his next step in spiritual practice.

 After the battle between the Blood Valley and the Red Demon, he was sure that his previous thoughts were correct.

Within one step, the gods and Buddhas retreated!

 This is the effect he wants to achieve at this stage.

However, he felt that he could now consider further compressing energy, and he was also considering another issue.

 Manpower is exhausted and beyond our capabilities.

Compared with the endless energy contained between heaven and earth, the energy contained in such a small body of a human being is ultimately limited. Just like in the blood lake, although the infinite true energy that Wang An realized and practiced, It was powerful, but compared with the almost endless blood lake, there was a big gap in "quantity" after all.

So, is there any way to make the energy in the human body infinite?

There are two methods. One is to maximize the use of energy between heaven and earth. What is between heaven and earth belongs to oneself. If this step can be achieved, the energy between heaven and earth is readily available. To a certain extent, it can be achieved. Endless, but this method has a big drawback. Once you are in a very limited space, or the space is "blocked" by someone, there will not be so much energy to borrow.

 Another method is to improve yourself as much as possible, enhance the "energy" quality in the body, and continuously compress and increase density.

 The gaseous state can become a liquid state, the liquid state can become a solid state, the solid state can continue to be compressed, a star can become a white dwarf, and a white dwarf can become a neutron star.

Wang An personally prefers the latter method.

  “Then the next thing to consider is the formation of pills.”

 He has successfully changed his own Qi form once, and now he is considering changing it a second time.

 “How to form an elixir?”

This is a professional term for a Taoist practice sect. The so-called "when a golden elixir is swallowed into the belly, my fate is determined by me and not by God." It refers to the cultivation of the golden elixir.

However, the method and effect of this kind of practice are definitely different from what Wang An thought and practiced.

He has read more than one such Taoist classic, but the descriptions of how to practice the golden elixir are very mysterious and there is no clear route. Perhaps the people who compiled these ancient Taoist books were not able to successfully practice the golden elixir in the end. .

Wang An is not in a hurry, he has plenty of time. One year won't work, two years won't work, two years won't work for ten years.

 He can already feel that his life span will be much longer than that of ordinary people, if nothing unexpected happens.

Thousands of miles away, on the outskirts of the crack known as the one leading to the underworld, a temporary military base has been built, and the sound of gunfire has been heard for several days.

 Monsters kept rushing out from there, not just humanoid monsters, but also ones with tails and weird wings. These monsters are fast, powerful and have high defense, causing huge damage to the warriors defending here.

 “Damn, what are these monsters, are they endless?”

 “This is not the way to go.”

“We have to find a way to go down and see what’s in there!”

 After several meetings to discuss and study, they suddenly carried out a strong counterattack. The fierce firepower suppressed the monsters that kept rushing out of the cracks, and at the same time, they delivered several specialized surveillance and observation equipment into the cracks.

 They want to find out what is in the crack.

 As a result, they saw black smoke billowing and monsters climbing up the rock wall.

Relevant equipment was destroyed again and again, and they were delivered again. After trying again and again, they finally saw a bronze door with a crack in the deep underground. The billowing black smoke and those weird monsters all rushed out from pressing the bronze door.

“In other words, as long as we find a way to close the bronze door, we can isolate these monsters and block this highly corrosive black smoke!”

“Theoretically, it’s like this, but the problem we face is how to dive to a depth of 254 meters underground amidst the siege of these monsters, and then close the bronze door that seems to weigh at least dozens of tons.”

“The distance of more than 200 meters is not a problem. We just need to dig out a passage on the rock wall. Open the passage first and then go down below.”

Digging a passage in a hard rock wall is not an easy task, but the base has specially invited a special team to have practitioners dig the passage and provide cover for them with automatic firepower.

Not to mention, the speed at which they dug passages exceeded many people's imagination. The originally hard rock was easily broken under their digging. The key was that these people dug passages and hunted monsters without fail.

“I didn’t expect these people to be so powerful. Let’s just put them down and see if they can close the bronze door.”

"No, now they can receive fire protection. Once they go underground, our firepower cannot provide them with all-round protection due to the obstruction of the rocks on both sides. The number of monsters they have to face will increase sharply, and it will be difficult to guarantee their safety. Safety."

 They dug passages in front, set up paving equipment, and then poured concrete continuously.

Just like this, in more than ten days, they actually built a downward passage. Although it was a bit rough, it could already accommodate two people going down side by side.

With the completion of the passage, special monitoring equipment began to be installed. The first team of people went underground. After more than half of the damage, they came to the bronze door.

Coming to the gate, they looked at the gate that was more than ten meters high in front of them. It was extremely thick and had strange runes carved on it. These people felt insignificant in front of these two gates.
