The process of refining spiritual weapons is extremely long, especially high-grade spiritual weapons, it is difficult to succeed without five days and ten days.

Lin Hao is not in a hurry, refining tools are the same as alchemy, what is important is to keep improving, not how fast!

Lin Hao continued to enter the magic tricks, and a new Heavenly Thunder Seal gradually took shape.

The days passed.

Five days later, the Nine Xuan Thunder Stone had formed a square, and no less than a hundred miniature magic circles had been arranged by Lin Hao inside, gathering Lin Hao's lifelong thunder magic essence.

If Lin Hao stops here, the Heavenly Thunder Seal of the top-grade spiritual weapon will be completed.

But Lin Hao was not satisfied!

Lei Yongxin is also good at thunder, he has been immersed in the baptism of thunder and lightning all year round, and he is resistant to thunder.

Lin Hao took out a turquoise demon core, this was a demon core of the Wind Demon King, from the fifth-order demon king Snake Meerkat King!

"Wind and thunder combine to create a new spiritual weapon, I don't believe it, and I can't subdue you!"

Lin Hao threw the demon core of the snake mongoose king into it, spat out a stream of essence blood, and condensed into a rune in mid-air and integrated into the demon core.

"Nine changes in wind and thunder!"

Lin Hao spat out the magic trick, and the whistling sound of wind and thunder sounded in the void.

Subsequently, under Lin Hao's subtle control, the Demon Core of the Snake Meerkat King and the Nine Xuan Thunder Stone fused together, turning into a square seal where blue and green meet.

At the moment when the two were combined, an invisible shock emanated from the void, and there was a faint thunderous explosion, and the entire cave was shaking.

The guinea pigs who had been sleeping all woke up and fled in all directions, and finally hid in the corner of the cave shivering.

In mid-air, the tremor that the heavenly thunder fused with the demon core could not imprint, and a slight crack appeared, as if it was about to explode!

Lin Hao continued to enter one miniature magic circle after another, and roared angrily: "Give me condensation!"

Under Lin Hao's full control, the originally extremely unstable Heavenly Thunder Seal finally stabilized, and the cracks disappeared.

Lin Hao frowned slightly, it seemed that fusing a wind demon core was not as simple as he imagined.

He released the human clone in the demon core space, let the clone control the stability on the side, and the main body applied the magic circle, so that it could finally continue, and the efficiency was improved a lot!

In the process of refining, another three days passed.

The Heavenly Thunder Seal in mid-air rotated quietly, looking like an ordinary stone that could no longer be ordinary, without spilling the slightest bit of energy.

Only Lin Hao knew that the terrifying power of this Heavenly Thunder Seal, once released, would be a shock!

Lin Hao's human clone was released, and with a move of his hand, he pinched the Heavenly Thunder Seal in his hand.

"Thunder ......"

Lin Hao clenched his fist, and a boundless and brilliant terrifying thunder erupted from the Heavenly Thunder Seal, making a crackling sonic boom, accompanied by a sharp storm howling, and the entire cave was shaking, as if it was about to collapse.

Lin Hao hurriedly stopped the release, the thunder and storm disappeared suddenly, and the cave stabilized.

"That's it, wait until you get to the City of Ten Thousand Beasts, and then try the power. ”

Lin Hao smiled and shook his head, if it was really released, even if the cave was blessed by him with a defensive formation, eighty percent would collapse.

He looked at the Heavenly Thunder Seal in his hand, and after blessing the wind demon core, the wind and thunder seemed to be fused together, and the thunder and storm were definitely a big killer.

If you want to talk about the level, the Heavenly Thunder Seal has far exceeded the level of the top-grade spiritual weapon, and has reached the category of the top-grade spiritual weapon.

After refining the Heavenly Thunder Seal, Lin Hao's divine sense was quite depleted, he swallowed a Soul Restoration Fruit, hovering on the ground and quietly repairing it.

After about an hour, Lin Hao recovered.

"It's time to go to the City of Ten Thousand Beasts and give Lei Yongxin a big gift. Lin Hao sneered.

Sun Xiang in the demon core space saw that he was dying, and Lin Hao fed him some water, so that he would not die of thirst.

Lin Hao climbed out of the room and came to the hall of the cave, after so many days, the original hundred guinea pigs have become one hundred and thirty, and at this rate, it will double in a month.

What surprised him was that the guinea pig king broke through to the second-order demon king, and a new first-order demon king appeared in the rat group, and the other guinea pigs all made more or less breakthroughs, I don't know if it was because of eating the warrior of the beast control village.

Lin Hao took out the corpses of several Beast Control Zhuang warriors and threw them on the ground.

"Remember, the person who wears such clothes is your food, and you will eat it when you meet it in the future!" Lin Hao said.

"Squeak!"

The guinea pigs swarmed up and ate the carcass in a few minutes.

The guinea pig has a very low IQ and can't speak, so he can only roughly understand what Lin Hao means, the demon king is smarter, and he squeaked twice at Lin Hao, indicating that he understands.

Lin Hao was not worried, as long as he kept feeding them the warriors of the Beast Control Village, when they saw the warriors of the Beast Control Village in the future, they would naturally think of food.

Lin Hao selected a group of strong and strong ones from the guinea pigs, including the second-order demon king, and all of them were included in the demon core space, leaving only the cubs and a few pregnant female rats here, and by the way, leaving a lot of martial corpses for them to eat.

Lin Hao climbed out of the cave and looked, the lightning was still lying on the tree, looking at the unripe soul rejuvenation fruit, and fell asleep after looking at it.

The silver bird broke through to the tenth level of qi training, but it was still in a state of cultivation.

Lin Hao's sense swept away, and he was surprised to find that the silver sparrow was on the verge of breaking through!

"What, it's almost time to build the foundation!" Lin Hao was stunned.

Even if it's the best spiritual root, it's not so fast!

It seems that since he knew the silver sparrow, the silver finch has been unusual, not only in the first-order demon beast to open the spiritual intelligence, but also in the sixth layer of qi training, he knows how to use true qi to simulate speech.

Thinking of the best spiritual root again, Lin Hao realized that the bloodline of the silver sparrow might be extremely powerful.

Lin Hao quietly climbed under the tree where the silver bird was, took out the only one hundred spirit stones left, and arranged a spirit gathering array.

"I hope this Spirit Gathering Array can help her. Lin Hao looked at the silver sparrow.

If there is no Zhuji Dan, many people will be stuck in the tenth layer of Qi cultivation for the rest of their lives, and they will not be able to build a foundation for the rest of their lives, and only a few geniuses will have an epiphany after being stuck in five or ten years and break through to the foundation level.

Like the Silver Sparrow, those who directly build the foundation are all peerless demons in the Middle-earth God Domain.

Of course, this does not mean that Silver Sparrow will definitely succeed, and it is not certain that the breakthrough will fail, at least she has now got the opportunity to have an epiphany.

Lin Hao turned his head to look at the sleeping lightning, and his divine consciousness transmitted to the past, and it exploded in the lightning's mind like a muffled thunder:

"Wake up!!"

"Ahh

"I'm going to go out, and during my absence, I can't leave here without permission, and when I encounter a powerful demon beast, hide in the cave, and wait for me to come back, understand?" Lin Hao said.

"Yes, boss!" said Lightning.

Lin Hao crawled towards the outside of the canyon and soon disappeared at the end of the canyon.

After Lin Hao left, Lightning fell asleep and snored like thunder.
