The reason why Zhao Xuan is so sure is because he has past life memories of the horned dragon being killed by humans.
In his past life memory, although the total number of human beings has been continuously decreasing in the apocalypse, the overall strength of the remaining human beings has also become stronger and stronger.
When mankind survived the disaster of World of Warcraft at the end of the world, the absolute masters among humans gradually became ninth-level king-level masters. At this time, no one can go further in cultivation and enter the War King realm after the War General realm.
The ninth-level human masters joined forces to fight against the ninth-level kings among other creatures, hoping to use the flesh, blood or crystal core of the ninth-level creatures to help them break through to the realm of kings of war.
The horned dragon that was currently crushing all humans was successfully surrounded and killed by human masters under such circumstances.
In his previous life, Zhao Xuan was not qualified to participate in that battle, but in this life, Zhao Xuan not only wanted to participate in the battle, but also got the largest share of the spoils.
Time passed by minute by minute, and soon, it had been two hours since the Hai Clan came ashore.
At this time, there was no intact building in Yunling City, and all of them had been flattened by the Hai Clan.
The horned dragon roared loudly, flicked its tail, and flew up into the sky back to the sea.
Many sea people also returned.
When the horned dragon plunged into the sea, the dark clouds in the sky instantly dissipated, and the wind and rain stopped instantly.
The world suddenly regained its clarity, as if nothing had happened just now.
If Yunling City had not been reduced to ruins in the eyes of many peepers, almost no one would have dared to believe that such a terrifying creature as a dragon had appeared before.
Without saying a word, many forces immediately started moving inward.
Everyone could see very clearly that the dragon was quite aggressive. This time, luckily, Yunling City was blocking the way, and the dragon didn't have time to fly to other places to do evil.
But what about next time?
No one dares to imagine that the next time the dragon flies into their territory, they will be spared.
The dragon can destroy large areas of the city wall with a flick of its tail, and the power of its body is self-evident.
This left none of them with the confidence to injure the dragon.
"Let's go to our new city." Zhao Xuan sighed softly.
The elite of Yunling City immediately followed Zhao Xuan and rushed to the new city.
For Zhao Xuan, the destruction of Yunling City by the dragon meant that the first stage of his doomsday journey had ended.
Next he will start the second stage of his journey.
As soon as Zhao Xuan returned to the City Lord's Mansion in Zhenjiang New City this time, Kuang Huayun found him with a face full of joy.
"City Lord, good news, great news." Kuang Huayun shouted as soon as he saw Zhao Xuan.
"Kang Gong, don't tell me yet. Let me guess. Have you successfully researched the crystal energy engine?" Zhao Xuan said with a smile.
"The city lord is really clever. Yes, the most difficult to research crystal energy engine has been successfully researched. From now on, our generators and engines used in machinery can be driven by crystal nuclei. We finally don't need to rely on gasoline, at least for power. No need to rely on gasoline." Kuang Huayun said happily.
"Okay, very good." Zhao Xuan was overjoyed.
He was extremely satisfied with Kuang Huayun at this time.
In his previous life, Zhao Xuan only knew that Kuang Huayun had developed crystal energy guns and crystal energy cannons, but he had never heard of crystal energy engines.
But in this life, Kuang Huayun, with Zhao Xuan's unconditional support, researched crystal energy guns early, and thus gained a very profound accumulation in the research of crystal core energy, making the power of crystal energy guns and The manufacturing speed continues to increase.
Not long ago, Zhao Xuan had some thoughts and proposed the idea of a crystal energy engine to Kuang Huayun.
Zhao Xuan didn't have high hopes for this, but Kuang Huayun really studied it.
"Kang Gong, do you have an application model for the engine?" Zhao Xuan asked Kuang Huayun immediately.
"Already have it. City Lord, please come with me to visit." Kuang Huayun said very confidently.
"Okay, let's go." Zhao Xuan stood up immediately.
Soon the two came to the heavily guarded production workshop.
In a room similar to a production workshop, Zhao Xuan saw two machines in operation.
"City Lord, please see, this is a crystal energy engine that is generating electricity. This engine currently uses level 1 energy crystal cores. Its fuel tank contains 200 level 1 crystal cores. It can drive a set of energy crystal cores with an output power of 300 A kilowatt generator set has a running time of 1,000 hours and a total output of 300,000 kilowatt hours. On average, one level 1 crystal core can be converted into 1,500 kilowatt hours of electricity. According to the same usage method, a level 2 crystal core can be converted into 6,000 kilowatt hours. Electric energy, level 3 is 22,000 degrees, level 4 is 85,000 degrees. The level 5 crystal core has not been tested yet, but it is expected to be 300,000 degrees." Kuang Huayun pointed to one of the machines and said proudly.
"Very good. In this way, our new city will no longer have to worry about power shortage. Let's talk about the vehicle engine." Zhao Xuan smiled.
"This is the vehicle engine. It is still testing the power in static operation, and the test has not been completed yet. According to the test data that has been obtained, the crystal core engine can convert the energy contained in the crystal core into traction kinetic energy almost 100%. If the engine is When filled with level 1 crystal cores, its maximum output power can reach 300 kilowatts and the output time is 940 hours. If filled with level 2 crystal nuclei..." Kuang Huayun pointed to another test machine and introduced it.
Listening to Kuang Huayun's introduction, although Zhao Xuan only showed a touch of joy on the surface, he was extremely excited inside.
Kuang Huayun didn't know how significant his research results would be. This is by no means a simple solution to the energy needs of surviving humans, but a huge problem for Zhao Xuan.
Zhao Xuan never took the current matter seriously. Even though the horned dragon destroyed Yunling City, he still didn't take it to heart.
He was preoccupied with thinking about the space relic that had not yet appeared but could determine the fate of mankind on earth.
According to the only information available, that space relic will appear in the southwest of China.
As for where it appeared, Zhao Xuan didn't know.
So Zhao Xuan needs to do a lot of work to successfully find the space ruins before the arrival of the Ancient Nass civilization.
This work begins now.
Kuang Huayun's successful development of the crystal energy engine at this time will give wings to his work.
"Kang Gong, if you don't care about the working time, what is the maximum output power of this engine?" Zhao Xuan asked calmly after Kuang Huayun finished the introduction.
"City Lord, this test has not been done yet. However, according to theoretical calculations, as long as the working time is not concerned, the maximum output power of the engine can reach 8,000 kilowatts." Kuang Huayun answered after a quick mental calculation.
"Great. Kuang Gong, do you know that this invention of yours is likely to save the entire human race!" Zhao Xuan was overjoyed and couldn't help but express his emotion.
Kuang Huayun was suddenly stunned.
He knew that his invention was great, but no matter what, it couldn't be elevated to the level of saving mankind, right?
