In just a few months, the planet had been completely united, and all the native intelligent beings had surrendered to Xiao Yu's feet. In the past few months, Xiao Yu has been recuperating silently. Xiao Yu only has one robot to use, and there are not many materials in reserve, and now Xiao Yu is only repairing and maintaining the most critical parts of the Hope spacecraft. These places are so important that nothing can be missed.

After the news that the country of savages had been completely destroyed was transmitted to the capital, the emperor led all the ministers to carry out a grand sacrifice to Xiao Yu again. All the intelligent creatures bowed in front of Xiao Yu with the most humble attitude, swearing to be loyal to Xiao Yu forever and would not rebel until death.

Xiao Yu also showed a miracle again at this time.

The grand voice was heard throughout the imperial city by Xiao Yu as the starting point: "My people, I have a vital task for you to do. I can't stay in the Land of the Oracle for long, after a while I'll leave here and head to the demon's lair to destroy all the demons so that they will never be able to do evil here. And in order to prevent any fish from slipping through the net during my absence, I decided to forge a sacred sword. ”

"It takes a lot of mineral essences to build the Divine Sword, so I need you all to mobilize them all to find them for me from all over the world and ship them here. I have found out where these minerals are stored, and I will give you a map of them later. ”

"The amount of minerals collected will be an indicator of loyalty, and whoever is loyal to me and believes in me, I will take you to heaven and let you enjoy the treatment of the gods. Go, my people......"

Under Xiao Yu's call. This whole civilization has been mobilized. The emperor regarded this incident as the best opportunity for him to show his loyalty, and even the emperor himself went out to lead the harem, ministers, and guards to a burial site of "mineral essence" to collect it. Officials from top to bottom, from all walks of life to all walks of life, from merchants to commoners, and even slaves, all enthusiastically devoted themselves to this cause.

Xiao Yu has demarcated more than 200 large-scale mining sites that are easy to collect and easy to transport, and all the gathering activities of this civilization are centered on these mineral bases. The enthusiasm of the intelligent creatures even exceeded Xiao Yu's expectations. Peasants gave up agricultural production, scholars gave up poetry and writing, officials gave up government management, and merchants gave up buying and selling...... The whole power of society was mobilized.

But this will not work, and this kind of social development is deformed. Without farmers, intelligent beings would starve to death sooner or later. There are no officials to manage government affairs. Sooner or later, society will have to be chaotic, and without merchants, goods cannot circulate. There was no way, Xiao Yu had to add an order again, declaring that the performance of various professions was also a kind of contribution, and asked the emperor to strengthen supervision. to alleviate this chaotic situation.

But even so, the whole society still operates around the extraction of minerals, and a large amount of social resources are invested in this area, which will inevitably lead to the impact of the rest. Intelligent creatures in the age of the nation. After all, the social economy is too weak. In order to prevent the occurrence of lack of food, clothing, and materials, as well as to comprehensively improve the labor efficiency of these people, and try his best to shorten the time he stays here, Xiao Yu has to spend energy to carry out scientific and technological transformation of this society.

Xiao Yu has come up with many technologies that can be applied at this stage, such as simple road repair technology, simple mechanical tools, simple lifting tools, smelting technology, planting methods that can increase yield, more efficient textile machinery, faster information circulation methods, and so on. Xiao Yu is driving himself to promote the rapid development of science and technology in this primary civilization.

"That's a little bit of a gift from me...... At this rate of development, in a few decades, it is estimated that your technology will reach the level of the first industrial revolution. Xiao Yu thought secretly, "The more advanced your technology is, the higher your work efficiency, the better it will be for me." It's meant to be a mutually beneficial thing. ”

Countless craftsmen are being recruited into the Imperial City, where they begin to learn the methods of forging and smelting that they consider to be divine arts, in preparation for the coming large number of primary ores. A large number of personnel are building on the other side, and under Xiao Yu's command, according to those drawings, strange-shaped buildings are being built. The roads connecting the Imperial City to the rest of the world have been widened and smoothed, and a large number of ore transport vehicles travel on these roads every day.

The main structure of the Hope spacecraft is made of microscopic particle polymer materials doped with a certain amount of python beast flesh and blood, and the rest of the details are made of a large number of different elements as materials according to different performance requirements. To repair the main structure of the Hope spaceship, Xiao Yu didn't have something as advanced as a sixth-level alien beast flesh or microscopic particle aggregation material to use. Xiao Yu assessed that with his current construction capacity, the most feasible thing is helium atomic polymerization materials. As for the restoration of the rest of the details, it is natural what elements were used in the original and what elements are still used.

The Hope spaceship also has very high requirements for ordinary elements, which means that Xiao Yu must build a large number of smelting factories and processing plants. But it is obvious that the current Xiao Yu does not have this ability. There is no way, Xiao Yu can only lower his requirements, as long as he can reluctantly use it, he will be satisfied.

Xiao Yu's "barely usable" is already an incredibly high requirement for this primary civilization. Xiao Yu tried for at least ten years, but never built a factory that met the standards. In desperation, Xiao Yu had no choice but to transform the target into a primary smelting plant, and then the finishing was carried out by the only robot, which was a little slower, but it could always produce qualified products.

Under such circumstances, a unique era of large-scale construction began. For Xiao Yu in the past, which era of large-scale construction does not mean that tens of billions of spaceships have been built, but this era of large-scale construction is just to repair a spaceship, or a small spaceship such as a township-level spaceship.

"This is all the strength of this primary civilization, after all, this civilization is too backward, it is extremely difficult to reach the current point, I can't ask too much." Xiao Yu thought with a secret sigh.

The only multi-functional robot in the Hope spacecraft toils day and night to repair all the damage on the Hope spacecraft. Under the hard work of this only robot, three years later, the regular drive engine and anti-gravity engine of the Hope spacecraft were repaired, which means that from this moment on, Xiao Yu once again has the ability to leave the planet and go into space for a short interstellar voyage.

Twenty years later, the curvature navigation engine was repaired, and Xiao Yu once again had the ability to sail with curvature. Thirty years later, the main body of the ship was repaired, and forty years later, the Hope has regained 80 percent of its full capacity.

It's time to leave. On this primordial planet, an eighty percent repair rate is already the limit.

Xiao Yu once again announced in a grand voice that the Divine Sword had been forged and that he was going to leave the Land of the Oracle and go to the demon's lair to destroy all the demons. Under Xiao Yu's control, the Hope spacecraft slowly left the ground and entered the sky.

"My people, after destroying the demons, I will return again to grant you eternal well-being and serenity. During my absence, the Holy Sword will protect you and destroy all demons who dare to violate them. ”

Xiao Yu said, manipulating the multi-functional robot to pull a big sword and fly over the imperial city, and finally stood it next to his statue. At this moment, the Divine Sword instantly bloomed with brilliant brilliance, illuminating the pitch-black night sky incomparably brighter, and it lasted for ten minutes before gradually dimming.

The Divine Sword was just made by Xiao Yu from the scraps of the Repair Hope spaceship, and then added some automatic defense systems to it, and the flash was just an ordinary light-emitting device.

"I have endowed the Divine Sword with divine powers, and as long as the Divine Sword is here, the Divine Nation will never be destroyed. Goodbye, my people. ”

Xiao Yu said, piloting the Hope spacecraft into space and continuing his journey. And on this planet, countless people are lying on the ground, and the shouts of "send off the gods" are endless.

"I hope that the next time I arrive, you will at least have stepped into the interstellar age...... In space, Xiao Yu took one last look at the planet and resolutely entered the curvature voyage.

After Xiao Yu left, the historian made this record: "The gods collected mineral essence and cast it into a sacred sword, and when it was cast, the wind and thunder surged, and the divine fire burned all day long, and it took more than 50 years to cast. Later, the Sacred Sword stood next to the icon and was the protector of the Oracle's Country. The gods said, "No demon would dare to invade the land of the oracles one day when the divine sword was there." ”

"After the divine sword was laid, the gods flew to the nine heavens, and before leaving, the gods said, I have gone to destroy the demons, and after all the evil demons have been removed, I will return, and grant the land of the oracles eternal health and tranquility." (To be continued......)
