The Cosmic Tree Fruit was discovered in the year 8325 of the Imperial Calendar, that is, more than 700 years ago. According to the time, the mecha had not yet been developed at that time, and things such as mechanical simulation structures and energy furnaces were still being conceived.

At that time, people's energy also came from a variety of inefficient energy sources, including various low-conversion energy furnaces, energy from some nuclear power plants, mineral combustion energy, etc., even if it was the most advanced energy furnace, the energy conversion rate would not exceed 50%.

(At present, the average energy conversion rate of internal combustion engines is about 30%, and the heat engine with the highest conversion rate is only a little more than 40%. ）

It can be said that the energy revolution in the new century, including the success of the design of mechas, comes from the perfection and construction of the prototype of the energy furnace. And the prototype of the construction of the modern energy furnace, all the ideas are derived from such a fruit - the fruit of the cosmic tree!

The Cosmic Tree Fruit contains extremely powerful energy, which is almost inexhaustible, which is the first truth confirmed by scientists after the discovery of this fruit. This kind of energy that never runs out is simply jaw-dropping.

You know, according to the current research, even if it's a star, even if it's a black hole, any collection of energy will eventually release their energy and eventually turn into cold silence. But this kind of law does not apply to the Cosmic Tree Fruit at all.

In such a miraculous fruit, the energy seems to come from a mysterious place, and it is not known where it comes from or how it is transmitted. But when the energy reaches the fruit, a cycle of energy is formed that is an eye-opener for scientists.

They used this almost lossless energy circulation method to design the initial model and output structure of the modern energy furnace, and for the first time, the conversion rate of scientific and technological energy in human society was increased to more than 50%, even if it only reached 50% 01 in an instant, this moment is still recorded in the history of the empire.

For more than 700 years in the following years, human beings began to carry out persistent research on the fruits of the Cosmic Tree.

Because it itself is like a magical fruit, and the fruit seems to be pregnant with a galaxy inside, all the energy is obtained from the depths of the universe, where humans cannot explore, so they named this fruit the World Tree Fruit.

In fact, for the study of the World Tree Fruit, they are far from reaching a beginner's level, and from a scientific point of view, such energy transformation is too complicated. Under the old professor's in-depth explanation, An Xiaoyu finally understood the meaning of some formulas and diagrams.

What is very surprising is that this fruit was not taken away by the upper echelons of the empire, but was allowed to stay in the Three Thousand Academy?

The old professor said embarrassedly: "If you take a closer look, the papers actually don't have the number of the Imperial Journal, that is to say, we have never taken out these studies, and the papers announced to the public are limited to the research results related to the energy furnace." ”

"In other words, you are hiding all the research results of the Cosmic Tree Fruit except for the energy transformation model?" An Xiaoyu smiled bitterly and shook his head: "You don't know what kind of impact this thing can have on the cultivation world...... But it's a blessing that it wasn't born 700 years ago. ”

"Do you know what this thing is?" The old professor asked unexpectedly.

"I don't know what this thing is, or if anyone knows. But I can tell you that this fruit is a portal, a mysterious space, a realm that is currently beyond the reach of science, even by practitioners. ”

"What field?"

"A realm of laws, the name is Avenue Space." Ann whispered.

Yes, the source of energy for the Fruit of the Cosmic Tree comes from the Great Dao Space.

Where exactly the Cosmic Tree Fruit was produced and what effect it had, An Xiaoyu didn't know anything. But when she tried to simulate the energy of the Cosmic Tree Fruit according to the data analyzed by the formula and the map on the paper, she found that this energy was exactly the same as the energy in the Great Dao space.

It is very likely that the inexhaustible energy of the Cosmic Tree Fruit comes from the Great Dao Space, so it can also explain the galaxies formed in the Cosmic Tree Fruit. It is normal to obtain the energy of the Great Dao and be able to form a space of its own and form a primordial cosmic form.

If this fruit is taken out and handed over to the cultivator General Alliance, the Lei family, and the Chu family, they will be able to further study the secrets of the Great Dao space, and even create a complete cultivation method above the Holy Realm and the Earth Immortal Realm, without still being explored.

However, thanks to the Three Thousand Academies that have hidden this thing, otherwise the strongest dynamic combat force in the entire continent is the Earth Immortal, and the Heavenly Dao will further release the authority of the Holy Realm cultivators, so that they can act like the True Realm, and the Imperial Capital will be a different scene.

It's creepy to think about.

Looking at the old professor's tangled face, An Xiaoyu sighed and said: "Now that I know this matter, the matter of the Cosmic Tree Fruit must have been intervened by the cultivators, even if it is recovered, it must be kept in the hands of the cultivators, and it may be able to be developed together, it depends on how you operate." ”

The old professor was suddenly uncomfortable, but An Xiaoyu had just saved his life, and this was the case, not to mention that the thing had just been thrown away, and it still fell into the hands of a foreign race, so he couldn't say anything, so he could only nod.

An Xiaoyu turned to the insect corpse that came up.

asked the old professor for a glass box, An Xiaoyu picked it up with the tip of a knife, packed the insect corpse, and after looking at it twice, he felt disgusted, so he threw it on the table: "It's an adult of the Arabian Nights, why did you become an adult so quickly?" ”

With that, An Xiaoyu came to the side of Shogo's corpse, looked at the hole in his eye socket, and found that the hole was already a cavity, not even blood flowed out, and the whole brain was covered with a white cotton wool-like object, which was creepy.

An Xiaoyu checked the corpses of other people again, and found that many of the people who fell to the ground also had their eye sockets flushed open, and their minds were in the same condition. An Xiaoyu frowned, feeling that things seemed to be beyond their imagination.

Guan Jue led people to the basement and asked An Xiaoyu: "How is it?" Lost something? ”

An Xiaoyu shook her head: "What you lost is not the most important thing now." ”

As she spoke, she threw the glass box containing the corpse of the Arabian Nights to Guan Jue. Guan Jue also frowned: "Arabian Night Clan? At this size, it should be a newly grown Celestial Nights...... Was it hatched after the last batch of Arabian Nights laid eggs? But why is it so fast? ”

An Xiaoyu pulled the head of a person next to him with his toes, exposed his empty eye sockets and said: "We are all wrong, the place where the Arabian Nights lay eggs is not a dark and damp natural environment, but in the human body, these people's brains have been eaten, and they have been controlled by the Arabian Nights these days." ”

The old professor shuddered when he heard this: "You mean, these...... These people are all dead a long time ago? ”

An Xiaoyu nodded.

I don't know if he was frightened or angry, the old professor pursed his lips and trembled. An Xiaoyu was afraid that something would happen to this old man, so he hurriedly sent him out, the reason was to save the scene and look for relevant clues.

And the matter of the Cosmic Tree Fruit was also reported to the gentle people.

Wen Liangren was also a little surprised when he heard it, for so many years, more than seven hundred years, the Ministry of Supervision had not found that the Three Thousand Academy still hid such a secret. They had seen the Cosmic Tree Fruit, and some of them had even used it, but they didn't pay much attention to it.

Probably because he is a martial cultivator, even if he comes into contact with the Cosmic Tree fruit, it is difficult to perceive the existence of space through the fruit, so he has been letting it go all the time. So the papers of the Three Thousand Academy have been studied in-house, and they don't know about it.

"The top priority now is to find out who the Arabian Nights have produced the insects to, now that the entire imperial capital is in chaos, if you want to conduct an orderly investigation, I am afraid it is already difficult, you can only dispatch some emergency strategies, such as ......"

An Xiaoyu interrupted Wen Liangren's words: "For example, ask the Nightmare Spirit Clan for help." ”

"Huh?" Wen Liangren glanced at An Xiaoyu, thought for a while and said, "This is a good way, then this matter will be left to Wusheng to do." ”

The Arabian Nights are a race that devours the souls of the gods, and the Nightmare Spirits have a strong ability to perceive the spirits of other races, and have the means to connect to the world of the void of reality, so they can search for the existence of the Arabian Nights and then expel them into the cracks.

But the problem is that the situation of the entire imperial capital is now unknown, so they can only let people take them to act together. And the Four-Life Alliance, which happened to negotiate cooperation with them and did not have much high-end combat power, was obviously the best candidate.

"Hey, hey! Are you mistaken, this is put aside from our discussion, and it is directly finalized? Wusheng was a little unhappy: "And although I am a real person, I still have the final say, you tell me that it is useless, you have to talk to that person!" ”

An Xiaoyu smiled: "It's okay, I know that Fusheng won't refuse." ”

Fusheng really didn't refuse, he had just negotiated terms with the Nightmare Spirit Clan, and the two sides just needed a cooperation to prove that the sincerity of both sides was true, and now the imperial capital was in such a situation again. After An Xiaoyu promised them the conditions to establish a station for them in the third home, Dream Flower Night readily agreed.

Wusheng had no choice but to do coolies, who said that he was the only one who could fight in the entire Four-Life Alliance?

After a night of war, the entire imperial capital finally began to calm down.

The ghost clan of Xishan didn't know where to go with the fruit, and after the Hong clan came to declare war, they didn't get an inch; The Nightmare Spirit Clan is leading the Beginningless Silkworm Clan to search for the remnants of the Arabian Nights, and the Three Thousand Academy is cleaning up the corpses of the Western Mountain Ghosts that exploded in the explosion.

It can be said that except for the accident of the Three Thousand Academy, the defense of the imperial capital this time was a complete success. With the Thunder Book in the hands of the administrator, the Book of the World came into play, establishing a peer-to-peer communication network for cultivators, and the repressive activities throughout the empire began to stay steadily.

The long dark night passed, looking at the smoke rising from the imperial capital, An Xiaoyu's faces were not at all relaxed.

Everyone knows that this is just the beginning.

With the official opening of the Great Spiritual World, the end of the beginning of the new millennium, and the official arrival of the new millennium, the entire continent will be plunged into a great upheaval. Thousands of years ago, it was their ancestors who solved the last catastrophe, and this time it was their turn, and no one dared to say that they were absolutely sure.

The appearance of this end indicates that the entire network of forces against the empire has passed some reorganization of interests, and the Origin, the End, the Hong, and other rebel groups and enemy alien races are slowly forming a huge force.

The failure to capture the Book of Thunder and the Book of the World was only because their previous information was too backward, and it was difficult to grasp the first-hand information of the Imperial Master without fighting. This led to the failure of the people they sent and the plans they set because they miscalculated the strength of the empire.

But what about next time?

The question turned into a haze that hung over everyone's heads.

Guan Shantong was the first to turn around and leave the Three Thousand Academy, and they could all see that he had gone to retreat.

Everyone understands this truth, if you want to always catch up with the opponent, you can only always take the initiative in terms of means and strength. As long as they come back, we still have a back hand to use and strength to retain, then we will have an extra chance of winning.

There was silence, and many people turned away.

Those Ann Xiaoyu knows, doesn't know, has seen before, and has not seen.

On this night, the end was aimed at far more than just the people around An Xiaoyu, but also many people from other forces in the imperial capital, and the people in the middle started various battles in various corners of the imperial capital.

Of course, not everyone survived, and many others did not even have a single corpse left.

Such a result can be regarded as a victory, but it cannot be regarded as a success.

This time, the empire completely fell into the inferior, and the people who ended it were like a group of crazy people, all the plans were done with all their might, all the heartbeat was unexpected, and the action was fast and well-organized, from leading An Xiaoyu to finally taking away the fruit of the Cosmic Tree, so many things were just a night of time.

If I had to do it again......

An Xiaoyu sighed, Guan Jue sighed, and everyone sighed.

The students of the Three Thousand Academy listened to the thunder of the battle all night, and the explosion of various energies spread incense in the sky, and no one was clamoring to go home anymore, and everyone stayed in the school honestly.

In order for students not to think cranky, the academy has accelerated the pace of learning, so that everyone has something to do, and there is little free time except for eating, drinking, and lazing, so that no one can have the leisure to think blindly and then do something stupid with a brain pump.

And An Xiaoyu has no time to study, according to the preliminary news from the location of the contact network established by the World Book, someone saw that there were ghosts from the West Mountains and a large number of moths quietly touched out of the imperial capital, and quietly sneaked in the direction of the mountains and forests of Jingxi Province.

They were discovered by a hermit sect living in seclusion on the border of Jingxi Province, and reported the discovery to the direction of the imperial capital as soon as they got the link to the time book. Originally, they wanted to report it, but it turned out that the communication could not be used at all, but fortunately, the connection of the time book came fast enough.

When they first received the news, they had just entered the mountains and forests of Jingxi Province in less than half an hour.

The Wartime Provisional Committee immediately decided to organize a team in the imperial capital to advance towards Jingxi Province, and through contact with the Jingxi Provincial garrison and the branch of the General Alliance of Cultivators, let a group of people outflank Jingxi Province and surround those departing Xishan ghosts on both sides.

And An Xiaoyu can't wait so much, her speed is much faster, especially after getting the three-element force, An Xiaoyu feels that her speed is still improving, probably because of the eternal power of the Xinghai energy, or because the three-element force makes her start to go beyond the scope of the Heavenly Dao.

An Xiaoyu's figure flashed through the air one after another strange bright spots, as if it was like a street lamp exploding, but he couldn't see An Xiaoyu's appearance, and in an instant, he arrived at the periphery of the imperial capital, and An Xiaoyu flew in the direction of Jingxi.

The Chu family is gloomy, from the beginning of the whole chaos to the present, the entire imperial capital has sacrificed the most, and the most serious loss of combat effectiveness is the Chu family and the Zhong family. How many people have died in the Zhong family and the Chu family so far? Now Chu Xuancheng is also dead, although he died at the hands of his own people.

But now Wusheng is a real person! A real person, and it is a new school of body cultivation, representing the absolute future of the new school of body cultivation, the empire will not let them go to Wusheng, regardless of whether it can be confirmed that he is Chu Tiansheng.

And after Wusheng passed this night, he was still so close to the Ministry of Supervision, and he didn't even express any opinion on the three thousand plum blossoms, doesn't this mean that the return of Chu Tiansheng and the rise of the Four Lives Alliance have been recognized by the empire, so their efforts have all become jokes?

"Now the situation is a foregone conclusion, and all the results will be seen on the battlefield." A saint of the Chu family said.

"The war is about to start, and if it is against the Four Beings Alliance at this time, it will be self-digging graves. Which of the descendants of the Chu family are good at war strategy? Another saint asked.

Several real people of the Chu family immediately looked at each other, and they all saw the jealousy in each other's eyes. If you let people from other branches take the position, I'm afraid that my own branch will decline in the future, just look at the current divisions, how many of them did not perform well in the last war?

"Humph!" A saint snorted coldly, and they all saw what these people were thinking.

At this time, an old voice said, "Just let Xuanfu go!" ”

"Ancestor!" All the masters immediately said respectfully.

This one, but a genuine old-school martial arts cultivator, a master retained from the previous era, a master of the Taishi realm, has been in charge of the Chu family for more than 900 years, and has truly experienced the existence of the last millennium war. Every family will leave one or two old-school body cultivators, just for this time.

After all, the Holy Realm can only live to be six hundred years old.

"Obey the order of the old ancestor and let Chu Xuanfu get out!"
