Li Xuan went back to retreat and cultivate before, which was easy to say, but in fact, in order to digest the memory fragment of the Supreme Demon Venerable, plus to adapt to the surging power in his body, it also took a month.

A month later, he came back to the Hanging Garden, where he could faintly sense the anomaly.

Not only was the hanging garden demon-stained, but with the hanging garden as the center, the surrounding area of more than 100 meters had been demon-dyed, as if it was surrounded by a pitch-black circle of light.

"Huh? Little friend, are you here again? The headless necromancer stood in the garden, looking at Li Xuan with some surprise.

The Demon Mind of the Supreme Demon Venerable had completely mastered this body, and the strength that he could exert was far beyond that of the "God Emperor".

However, this old devil is not very calm in his heart now, he personally sent a drop of the world origin with demon stain, which can be said to divide the harvest in this world into three.

It stands to reason that it is enough to pollute a fifth-order powerhouse, and even pollute the other party's world!

But now that Li Xuan has arrived again, there is no trace of demonic dyeing on his body.

"Brother, the World Origin you gave me last time was very good, and I sacrificed it to the Heavenly Dao of our world. With the blessing of the Heavenly Dao, my cultivation has broken through two small realms in a row. Li Xuan flickered at the supreme demon venerable's demonic thoughts.

"I see." The Supreme Demon Venerable suddenly swooped down.

It turned out that the other party did not swallow that drop of the world origin at all, but sacrificed it to the Heavenly Dao, which can be said.

If you don't use the World Origin, you will naturally not be assimilated by Demon Dye.

And that drop of world origin is still in the other world, and the Supreme Demon Venerable is just a demon thought that has just awakened, and its strength is limited, and it is impossible to sense the situation in the other world through the world and chaos.

"Dude, you are a good person to the end, can you give me another drop of the origin of the world?" Li Xuan can be said to have put the temperance out of the way, and his face is extremely thick.

Demon Venerable sneered, do you really think he is a fool?

Even if this kid acted very similarly, he didn't check it for a while before, and almost believed it. But what kind of character is his Supreme Demon Venerable?

It's definitely cunning!

"It seems that the World Origin has no effect on you, there are other powerhouses behind you, right?" Demon Venerable said lightly: "Also, the forces that can cross the world, how can they be idle?" ”

Li Xuan touched his nose a little embarrassed, knowing that he couldn't fool this old devil, and he didn't bother to talk nonsense, so he turned his face directly.

"Fire Phoenix, cloth [Eight Desolation Xuanhuo Burning Heaven Array]!"

The eight fire phoenixes roared in unison and flew to the eight directions of the air fortress, pushing the phoenix flames and arranging the formation.

This is one of the top formations in the world of the Three Kingdoms of Gaowu, and the eight fire phoenixes work together to set up the formation, and the power is comparable to that of the powerhouses in the early stage of the fifth order!

"It's just such a small measure, it's not enough for me." Demon Venerable didn't even bother to move, he just sneered: "I haven't eaten a phoenix for a long time, this kind of low-grade phoenix clan with impure blood can just stuff my teeth." ”

The eight phoenixes looked dull at the same time, their formations collapsed, and they fluttered their wings and flew towards the hanging garden.

Big murderer!

Even if the Supreme Demon Venerable was just a wisp of demonic thought, it was enough to crush the fifth-order combat power.

"Come back!" Li Xuan hurriedly urged the Gate of Tianwei and forcibly manipulated the bodies of the eight phoenixes through the seal of the Gate of Heaven and Dimension, allowing them to come back.

After leaving the Hanging Garden for some distance, the phoenixes regained their freedom, and they all trembled, not daring to take another look at the Demon Venerable.

These eight phoenixes were originally cannon fodder brought by Li Xuan to test the strength of the Demon Venerable.

Since the fifth-order combat power was easily defeated in front of the Demon Venerable, Li Xuan naturally would not rush over and die again.

……

A month later, most of the necromancy on the Azure Star had been cleansed by the masters of the Tang Empire.

Even the "Eight Great God Kings" did not escape the catastrophe and were found out and killed by Li Xuan.

Every time a high-level necromantic is killed, the Gate of Tianwei can absorb a trace of the demon-stained world origin, and the collection of small amounts adds up to a lot, and it even has enough of 500,000 origins.

In addition to the origin harvest, the Tang Empire also harvested a complete industrial civilization system, as long as these technologies were digested, they could directly leap to the level of science and technology equivalent to Li Xuan's previous life Blue Star.

The only regret is that cutting-edge technologies such as plasma cannons, mechas, manned spacecraft, anti-gravity technology, and super artificial intelligence have all been destroyed, and no relevant information has been obtained on the Azure Star.

Needless to say, this must have been done by the Demon Venerable to let his subordinates do it!

"Your Majesty, we have found something good!" On this day, Cao Cao came over in a hurry.

"What did you find again? Mecha? Li Xuan didn't blink.

Cao Cao smiled and said, "No, we found a nuclear arsenal with more than 100 nuclear bombs remaining in it!" ”

Li Xuan's eyes glowed with gold, and it seemed that he had the opportunity to grow mushrooms with his own hands.

"You guys gather all those nuclear bombs, I'm going to give a gift!"

Before, the Demon Venerable gave him a drop of the origin of the world, Li Xuan is not a stingy person, the courtesy is still exchanged, he naturally wants to return the gift.

That night, a small sun bloomed near the Hanging Garden of the Demon Venerable, and more than 100 nuclear bombs exploded in unison, including Big Ivan, who had a yield of 10 million tons.

Rao is the hanging garden is extraordinary, after all, it can't be moved, and in order to resist this round of nuclear explosion, a lot of energy is consumed.

Li Xuan had a feeling of sudden realization, if he wanted to deal with the Demon Venerable, he still had to go to the mushroom bomb!

Bombing once a month, throwing out more than 100 large Ivans with a yield of 10 million tons can effectively suppress the speed at which the Demon Venerable becomes stronger!

But here's the problem, the Tang Empire doesn't have enough nuclear bomb storage, and if you want to mass-produce Big Ivan, you can't do it in a short time, and you have to wait for them to digest the technology of this world.

"Your Majesty, before the end of the world, the human race of this world carried out an ark plan, and connected a group of the world's top scientists and elites to the manned spacecraft, flew to space, and went to the dungeon of Gaia Star." Jia Xu reminded beside him: "In order to deal with the possible crisis, those remaining human elites must definitely produce some weapons to protect themselves. ”

Not to mention whether there is an arsenal that produces mushroom bombs in the dungeon, but there must be quite a few experts in nuclear weapons.

After some deliberation, the Tang Empire sent an envoy to leave the Azure Star and fly into space to the dungeon of Gaia.

The Tang Empire naturally does not have a large manned spaceship, but the magic weapon of cultivating civilization is not bad.

The flying boat left by Zhang Daoling, the original Heavenly Master, was a fifth-order magic weapon, and its usual flight speed could reach thirty times the speed of sound!

The speed of sound is 340 meters per second, and the speed of sound is 10.2 kilometers per second, which has surpassed the first cosmic speed and can fly into space.

The higher you fly, the thinner the air and the less air resistance. Once in space, the speed of the spacecraft can even reach 30 km/s!

This speed far exceeds the second cosmic velocity, and it can break away from the gravitational pull of the blue star and fly to Gaia.
