Jiang Yi actually didn't know.

There are two ways to obtain thunder stones on Tianlei Island, the first is to wait for the thunder stones to erupt near Lei Mountain, and the second is to dig thunder stones in Lei Ling.

Normally, almost all people would follow that avenue to the vicinity of Thunder Mountain and wait for the Thunderstone to erupt before snatching it, because this is the safest place. When there is a thunder fire erupting from the Thunder Mountain, the temperature will gradually increase, so everyone can avoid it in advance. Moreover, the ten thunder mountains are occupied by the ten forces respectively, and there will be no conflicts and disputes.

The reason why there are only ten overlords in the city is because there are only ten thunder mountains, and if someone wants to become the eleventh overlord, they must kill one person and snatch a thunder mountain, so that someone will be attached.

The ten overlords all secretly agreed that they would not compete for the thunder stones shot from the Thunder Mountain to which the rest of the forces belonged. So the thunder mountain erupted the thunder stone just now, and the people nearby didn't dare to grab it.

The top ten overlords also have orders, Lei Shi is obtained by strength and luck, before no one gets it, it can be fought for but not killed, whoever grabs it is not allowed to snatch it, at least... You can't do it on the surface, but you can grab it secretly, that's your ability!

Of course, there are also people who try the second method, such as some newcomers, or people who are weak and can't grab the thunder stone, they often take risks, but in the end, those who enter the thunder ridge are dead.

Although the thunder and lightning in this sky are basically split on the ten thunder mountains, they will occasionally split on the mountains of the thunder ridge, and the thunder and lightning will split on the black stone in the thunder ridge, which can also give birth to the thunder stone.

At the same time as breeding thunder stones, thunder fire will also be generated, thunder fire is too terrifying, ordinary martial artists will never be able to get close, and thunder fire can also kill divine consciousness. Martial artists who are familiar with the horror of thunder and fire avoid thunder ridges like snakes and scorpions, and ordinary people will venture into thunder ridges unless they are cornered.

Jiang Yi didn't understand these things, but as long as he was sure that what he dug up was indeed a thunder stone, that would be enough!

He retracted his thoughts and turned around and ran towards the depths of the Thunder Ridge, he wanted to collect enough thunder stones, so that they could live comfortably in the city and spend a year of service safely.

His body flew away like lightning, and his eyes scanned around, looking for a place where there was thunder and fire!

He has a fire spirit bead, he is not afraid of high temperatures at all, and he walks freely in the Thunder Ridge, as long as he is not touched by the thunder and fire spewing from below, this place is no different from his back garden.

If Jiang Yi flew in the Thunder Ridge so easily and was known by the martial artists in the city, the whole city would definitely be shaken. Thunder Ridge is very large, and for so many years, it has also produced enough thunder stones. No one excavates the thunder stone here, Jiang Yi is too easy to dig, and it can make the martial artists in the whole city envious, jealous and hateful!

One hour, two hours, four hours!

Jiang Yi scurried around in the Thunder Ridge like a monkey, and in four hours, he dug up at least 800 Thunder Stones. They need to hand in nine thunder stones a day, ninety in ten days, and at this moment he has more than eight hundred thunder stones, which can almost support a hundred days, more than three months.

"Almost, huh?"

Jiang Yi looked at the sky, it was almost dusk, but he remembered that everyone entered the city at dusk, and no one came back at night. There was no thunder and lightning at night, so there should be no thunder stones spewing out, so everyone would return to the city. But caution is the best, anyway, he has more than 800 thunder stones, which can support him for a few months.

He rushed towards the Heavenly Thunder City, he entered the state of unity of heaven and man, integrated into this heaven and earth, his speed is not fast or slow, if there is any wind and grass, he will know it as soon as possible. He was ambushed by four Heavenly Monarch powerhouses in the morning, so he naturally had to be cautious.

Flying all the way, all the way safe, half an hour later, he arrived thirty miles outside the city gate, if he didn't close his eyes, he should be able to see the huge Heavenly Thunder City from afar.

That's when it happened.

His body stopped suddenly, because he noticed that there was something different in front of him, there were a few breathing sounds in front of him, the sound was very slight, but he entered the state of unity between heaven and man, and he was the most sensitive to the situation around him, and some subtle differences could be noticed.

"About a mile ahead, in the small mountain col, there are four people! It seems that they are the four Heavenly Monarchs. ”

Jiang Yi's mind was spinning rapidly, he quietly retreated, took a turn around, and soon found a place with thunder and fire, he stood on the top of a small mountain, opened his eyes, and frowned tightly.

The location of the ambush of these four people is very ingenious, this is so close to the city, if you want to enter the city, you have to pass by them, Jiang Yi can actually keep teleporting into the city, but his speed is too slow, it is estimated that he will be caught up before he reaches the city gate.

"Kill these four!"

In the end, Jiang Yi made a decision, he had an incomparable advantage. The other party didn't know that he had four Heavenly Monarchs, if he released Jiang Xiaonu and Fengluan Jin Jiao from the imperial palace in an instant, he would definitely be able to kill them by surprise, and the four of them attacked two of them separately, even if they didn't die, they would have to be hit hard!

These four people have chased and killed him twice, and he also has some understanding of the attack power of the four people, not too strong, the only thing that is a little terrifying, only the strongest Heavenly Monarch, there is a shuttle-shaped treasure, that should be a super holy weapon.

If the four of them kill him together, the other three will have to wait for death, after all, Feng Luan's dark Dao pattern is a group attack, shrouded in the dark Dao pattern, and the other three can't escape at all.

At this moment, the three of them were still lurking there, and they didn't know that he had detected them in advance through the state of unity of heaven and man, and the four people in this thunder ridge should not dare to release their divine senses rashly, after all, there was a thunder fire here.

Count with your heart and not with your heart!

Plus the four of them teamed up to sneak attack, and the odds of winning on their side reached eighty percent!

Jiang Yi made up a plan, immediately took out the imperial palace, and began to transmit the sound to Fengluan Jin Jiao and Jiang Xiaonu, the three of them had been worried about Jiang Yi, and they immediately rejoiced when they heard the transmission.

Jiang Yi told the three of them about the situation, discussed it, and the fire dragon sword in his hand quietly appeared, entered the state of unity of heaven and man again, and slowly flew forward.

Five miles, three miles, one mile!

The four of them were still hiding in the dirt of the mountain col, Jiang Yi pretended not to detect it, and his head turned left and right, like a lewd thief. He didn't exude his divine sense at all, and the people below didn't reach out either, as if neither side had discovered the other.

Three hundred zhang!

One hundred zhang!

"Bang!"

The mud and stone below burst out, and four figures rose into the sky like a wild dragon, and a shuttle glowing with cold light shot straight at Jiang Yi twice as fast as them, and at this moment, Jiang Yi disappeared.

"Hmm..."

The eyes of the four people blinked, and there was a look of disbelief inside, so far away, everyone thought that they would be killed with one blow, but they didn't expect Jiang Yi to react so quickly?

The four of them swept their eyes to the west at the same time, they all thought that Jiang Yi would flee towards Tianlei City, but they didn't find Jiang Yi's figure after sweeping it?

A trace of doubt flashed in everyone's heads again, and a slight sound of breaking the air suddenly came from below, waking up the four people, and the four pairs of eyes swept downward, just in time to see Jiang Yi's figure condensed below them.

"Buzz!"

Almost at the same time, Jiang Yi's imperial palace lit up, three figures appeared in mid-air, Feng Luan's hands danced like lightning as soon as she appeared, and a black qi condensed around her, instantly covering this piece of sky.

"Whew!"

Jiang Xiaonu had already transformed when she was in the imperial palace, and the aura on her body was the most terrifying, a pair of green eyes made the four of them tremble, and the pair of phoenix claws glowing with green light carried the breath of death. As soon as Jiang Xiaonu appeared outside, she immediately broke through the air, and before everyone was shrouded in darkness, one of her giant claws had already grabbed the head of Fei Guo Tianjun.

"Little slave, come back!"

Jiang Yi was shocked, he had just transmitted the message to Jiang Xiaonu, so that she could wait for the opportunity to move, and after they attacked for a round, he found the right opportunity to attack, but he didn't expect that the fire dragon sword in his hand had just lit up, but Jiang Xiaonu had already broken through the air......
