After a long journey during the day, it was night again, this time Qin Mu simply no longer looked for the ruins to rest, but let the box carry the sleeping dragon qilin to hurry at night, while he walked in the dark and followed the box.

He had seen many strange things in the night, many cities that had suddenly sprung up with the darkness, countless creatures, and battles of great scale that he had never seen before before he had followed the village chief into the dark ruins.

And every time he stepped into the light of the box, he could not see the scene in the darkness, and the divine light of the box seemed to allow him to travel to the original world.

To step into the darkness is to travel to another world, the Dark World.

Strangely, he doesn't feel the world barriers.

It's almost impossible to happen.

There will be a world barrier between any two worlds, and if you pass through the two worlds, you will be squeezed by the forces of different worlds, and the stronger the power of the traverser, the stronger the squeezing force.

And there is no barrier between the dark world and the real world, which is weird.

Qin Mu walked into the light of the box, sat on the box and was stunned, his eyes suddenly lit up, and he said with a smile: "I know an expert in this area, ask him to come out and ask if you understand?"

In high spirits, he stopped the box, jumped off the box, and took out a bone altar from the gluttonous bag, on which was a four-headed and eight-armed demon god statue.

Qin Mu took out the cinnabar pen and drew various runes on the statue of the demon god, and then the vitality urged the rune treasure to perform the magic power of the ghost and send the rune word.

After a few moments, he finished his work, and the Demon God Statue remained motionless.

Qin Muhu was suspicious, and cast it again, but the Demon God Statue still didn't react.

"Brother Dutian, the younger brother is sincerely afraid to summon the eldest brother to come, offer flesh and blood delicacies, and ask the eldest brother to move the jade toe. ”

Qin Mu prayed: "If Brother Dutian doesn't come, Brother will pray ten times a day and a hundred times until Big Brother comes." My brother knocked down and was terrified......"

"Shut up, who's your big brother?"

The statue of the demon god suddenly opened its eyes, and the beads of its eyes turned around rapidly, and he didn't find that he was being plotted, and then a wisp of consciousness came, and the other three faces suddenly came to life, and said: "I haven't bowed to you, don't recognize relatives, we don't know each other! Pray a hundred and ten times a day, Lao Tzu has to be annoyed to death by you! Sect Master Qin, what did you call me to?"

Qin Mu breathed a sigh of relief and said with a smile: "I have something I don't understand. ”

He recounted what he had seen and heard in the dark, and said, "Why do the two worlds overlap, why did they pass through without encountering world barriers and being rejected?"

The puppet god stood up from the altar, pulled out a white bone and put it in his mouth, as if eating a sugar cane, and said, "I thought you summoned me with some kind of conspiracy, but it turned out to be such a trivial matter. ”

Qin Mu held the disciple salute and said, "Dare to ask Brother Dutian for advice?"

The Dutian Demon King was terrified, and hurriedly said: "Don't be so polite, you are so polite, I always suspect that you want to give me small shoes to wear! What you said actually involves the problem of world energy." A world, the energy that makes up the world is fixed. A person's birth, cultivation, or death do not change the composition of the world's energy. This is the most basic rule!"

Qin Mu thought for a moment and suddenly said, "A person's birth, cultivation, and death will not change the composition of energy, so what if this person becomes a god and a demon, and is immortal and immortal?"

"Even if you become a god and become a demon, it will not change the fixed energy of this world, it will not make the energy of this world increase, and it will not make the energy of this world less. ”

Dutian Demon King said: "The energy of the world is constant, and the energy that can be changed is limited. When a person crosses from this world to another world, it will make the energy of this world less than one person's energy, and the energy of another world will increase the energy of one person, breaking the original balance, and will cause twice the strength of the person himself acting on him, so it is difficult to cross the world, and flesh and blood sacrifices are required. ”

Qin Mu suddenly had a feeling of enlightenment, and said: "The principle of flesh and blood sacrifice is to sacrifice the flesh and blood of the creatures of this world, sacrifice them to another world, and turn them into the energy of another world!"

The Dutian Demon King nodded: "And the sacrificed gods and demons descended from another world to this world as the energy in exchange to fill the lost energy of the flesh sacrifice, so as to maintain the energy balance of the two worlds." For example, on your altar, the energy in the bones on the altar was sacrificed by you just now, and sacrificed to my heavenly world. And in exchange for energy, I have descended into your treacherous world. ”

Qin Mu's eyes lit up and said, "I see." What did you mean by the limited amount of energy that can be changed?"

"Flesh and blood sacrifices, building bridges, running through the two realms. If my power is strong enough, I can smuggle some of my power into the bridge and not follow the energy balance. ”

The Dutian Demon King smiled: "Last time you summoned me, the power of sacrifice was very small, and I mobilized a lot of energy to descend on this world. This is equivalent to forcibly squeezing in, but the energy that squeezes in requires me to withstand the pressure of two worlds, so the power that can be squeezed in is still limited, and it will soon exceed my limit. The strength of the smuggling depends on the strength of the sacrificed. ”

Qin Mu suddenly frowned, "However, in the darkness of the Great Ruins, there is no world barrier between the two worlds, how can this be explained?"

The Dutian Demon King smiled and said, "What if the energy squeezed in exceeds the limit that this world can bear?"

Qin Mu's heart was shocked: "What do you mean ......?"

"A large-scale flesh and blood sacrifice has built tens of thousands, hundreds of thousands of bridges, tens of thousands, hundreds of thousands of gods and demons smuggled together to instill their own energy into that world!"

The Dutian Demon King smiled gloomily: "Burst the barriers of that world! The barriers of the world have been blown open, and there are no more barriers, and then you can enter in a big way, without any obstacles!"

Qin Mu was terrified, fought a few cold wars in a row, showed a look of disbelief, and said in a lost voice: "You mean, the world in the darkness of the ruins is a world that has been broken up by the world barriers?"

"What is blown up may not be the world in the dark. ”

The Dutian Demon King smiled and said, "Don't you think that your world may also be a world that has been blown up?"

Qin Mu shook his head: "If this world was blown up, you would have been able to come at will." I saw that world in the dark, countless demon gods opened one space hole after another, and led the demon son and demon grandson to kill it, it is conceivable that it is that world that has been blown up by the world barrier. ”

The Dutian Demon King sat on the box, snorted, and shook his feet: "I listened to your description, the world in the dark overlapped with this sinister world, which reminded me of a very terrifying possibility. World Sacrifice!"

An extremely eerie smile appeared on the faces of his four puppets, and he was so excited that he almost jumped up: "World sacrifice is to sacrifice the entire world, and use this terrifying power to descend to another world, and millions of gods and demons will descend together to destroy that world!"

Qin Mu was surprised: "They are going to destroy that world?"

The puppet god squeaked its head, and the gazes of the four faces fell on him one after another.

Qin Mu's hair stood on end, and he lost his voice: "You mean, there are tens of thousands of demon gods who have crowded the barrier of that dark world, and then plan to sacrifice blood to that world and descend on us?"

The Dutian Demon King's head snorted around his neck for a few weeks, and he stroked his palms and praised, "Clever! The energy of sacrificing a world is so huge and so terrifying, it can make that world full of demon gods descend on the ruins in one fell swoop! At that time, there will be a terrifying scene of two worlds colliding, and hundreds of millions of lives will be destroyed, it's really exciting to think about!"

Qin Mu's expression was sluggish, and he suddenly shook his head and said, "Impossible, absolutely impossible! The darkness has existed for 20,000 years, doesn't this mean that the war in that world has existed for 20,000 years, how can there be a war that lasts so long?"

The Dutian Demon King jumped down from the box and said, "If I were you, I would have emigrated to another world a long time ago. The world is too dangerous, I want to go back! Also, don't bother me often, I'm afraid of you!"

He jumped into the darkness, his consciousness left his body and returned to the Dutian world, shouting, "When the world in the darkness is destroyed, it will be the day your world collides with another demon god world, and it is also the day you will fall!"

He jumped into the darkness and was immediately eroded by the darkness, Qin Mu hurriedly rushed into the darkness, only to see the puppet demon statue shattered to the ground.

Qin Mu frowned, and returned to the side of the box, the energy of the White Bone Altar was exhausted, and the white bones were also shattered.

"Is the words of the Dutian Demon King reliable? This guy has always been unreliable, and now he is so scary......

He made up his mind, the words of the Heavenly Demon King were really terrifying, how much credibility did he have?

But think about it, with the schadenfreude of the Heavenly Demon King, there is no need to scare him.

"Yankang is still too weak. ”

Qin Mu exhaled a breath of turbidity and said in his heart: "However, the world in the dark has been fighting with the demon race for 20,000 years, and if they persist until now, they will not collapse now and be sacrificed by the other party's blood, right? Therefore, the collision between Yankang and the demon world should be a long way away, so don't worry too much...... Hehehe, I was almost scared to pee by Du Tian, people are worried, they must be worried!"

After a few days, Qin Mu finally walked out of the ruins, returned to Yankang, and immediately rushed to the capital through the spaceship of Mishui Pass, and presented the Xuanwu beads paid tribute by Xiong Xiyu, the master of the True Heaven Palace, and talked about building the road.

Emperor Yanfeng convened the civil and military ministers to discuss the matter, and the Yankang national teacher was also among them, and the civil and military ministers had different discussions, and many opposed the construction of the road. Emperor Yanfeng said with a smile in the court that he wanted to kill his head, and then the matter of building the road was finalized.

Emperor Yanfeng handed over the matter to the Ministry of Industry to take care of, and Yankang Guoshi was in charge. Qin Mu immediately found the Yankang National Master and said, "The divine power of the Western Earth is very suitable for my teaching, and the Heavenly King has brought several elders and hall masters of our Holy Sect to recruit some more people to join the sect." ”

Yankang National Master wondered, "Sect Master Qin, it's not appropriate to leave this matter to me, right?"

"You are the Four Heavenly Kings of the Holy Sect, so naturally you are in charge. ”

Green tendons appeared on the forehead of Yankang National Master, and he said firmly: "What about the sect master?"

Qin Mu said with a smile: "I'll go to find relatives and friends, and then do business and make some money." ”
