Xu Feng naturally felt it, and there was a group of teenagers behind him, but he didn't care, although the other party was all genius teenagers above the planetary level, but for Xu Feng, they were just a group of rookies who had never seen blood.

Xu Feng just glanced at them, and he could already see that they did not have the slightest bloody aura on them, they should be students from a certain academy, and they were still childish, and they did not hide the energy fluctuations of the planetary-level powerhouses on their bodies.

For Xu Feng, such a person even only needs one hand, and at the cost of a little injury, he can kill them all.

After continuing to fly forward for three or four kilometers, Xu Feng already faintly felt that the strong pressure spread outward in the area in front of him, and the dazzling lightning across the entire galaxy, before entering the thunder domain, it already gave people a sense of threat that destroyed the world and destroyed the world, and once entered, there would be no bones.

"This is only the edge area of the Thunder Domain, it is already so terrifying, how terrifying should the purple thunder array area in the depths of the Thunder Domain be!" Xu Feng took a deep breath and said secretly in his heart.

Flying towards the thunder domain, a thunderbolt the size of a bucket flew towards Xu Feng, like a thunder god's whip, and slammed it on his body.

"Hiss~" Xu Feng gasped, and in the void, he retreated five or six meters away directly, his body was sore, and within a few seconds, he even lost control of his body.

"The lightning damage here is so terrifying, how can anyone choose to temper their bodies here? Just an ordinary lightning bolt has such damage, if you continue to go deeper, who can withstand it? Xu Feng said secretly in his heart, and he couldn't help but hesitate a little in his heart.

"Master, you must first find a planet on the edge of the thunder domain and find a place to live, and then you can start to use thunder and lightning to temper your body, if you accept the thunder and lightning bombardment like this, even if you are a master-level powerhouse, you can't last long!" Little Q's voice came from the communicator.

"I see, little Q, the closest planet to the edge of the Thunder Domain, that one, guide me through!" Xu Feng said.

"The closest planet to the edge of the thunder domain is a planet called the Sky Thunder Star, and here is also a deserted thunderstone mining planet, flying in the left-hand direction, about sixteen stars away, you can see it." Little Q said.

Soon, under the guidance of Xiao Q, Xu Feng flew towards the closest planet to the edge of the thunder domain, along the way, countless thunderbolts kept bombarding Xu Feng's body, Xu Feng gritted his teeth and insisted, if it wasn't for the use of life essence elixir, the strength of his body had increased more than ten times at this time, I am afraid that Xu Feng would not be able to hold on to the Heavenly Thunder Star at all and would be forced to return.

"The gray planet up front is!"

After flying for more than half an hour, Xu Feng also endured dozens of thunderbolts, and finally saw a gray-white planet, floating quietly in the void.

Xu Feng hurriedly adjusted his direction and flew towards the gray planet;

Having entered the atmosphere of the gray planet, Xu Feng fell down at an astonishing speed, like an uncontrolled meteorite, surrounded by endless thunder and lightning like silver snakes, and the howling wind in his ears, Xu Feng was shocked, and hurriedly summoned the tiger wings wind thunder wings, only to slow down the speed of the fall slightly.

Rumble~

Xu Feng was like a meteorite, smashing into the ground of the Heavenly Thunder Star, and at this time there were fine crystal particles under his feet, the color was the same as the color of this planet, showing a strange gray-white color.

"The spars here are all abandoned thunderstone mineral residues, originally this planet was full of thunderstone deposits, but after tens of thousands of years of excavation, the thunderstone here has been all excavated, these are waste ore residues, there is no use." Q explained.

Rumble~

At this time, thunder and lightning fell from the sky, as if attracted by Xu Feng, and an arc crossed in the air, hitting the top of his head.

"Hey, the power of thunder and lightning here seems to have weakened a lot." Xu Feng was surprised to find.

"Yes, the thunder and lightning on the planet are much weaker than the thunder and lightning in the universe, and no one knows the reason, so they can only adapt. At the edge of the Thunder Domain, there are many abandoned planets like the Celestial Thunder Star, and if you want to temper your body with thunder and lightning, you must first adapt to such a planet for a period of time. Little Q said.

Xu Feng nodded, it was impossible for him to forget that he was not here to refine his body, but to enter the purple thunder array in the depths of the Thunder Domain, break the robbery chain on his body, and break through to the planetary level.

However, if you don't use the thunder and lightning to temper your body first, I'm afraid that before you reach the thunder array, you will already be scattered by the thunder in the thunder domain.

"The first step in tempering your body is that you can't wear any equipment on your body!" Little Q said.

Xu Feng nodded, took off all the equipment on his body directly, and put it into the package, the equipment is part of a person's strength, and took off the whole body defense equipment, Xu Feng suddenly felt that he was a lot weaker, and his physical attributes also dropped a little.

Rumble~

Another thunderbolt fell, Xu Feng was careless for a while, he actually felt trembling all over, his chest was a little stuffy, and he couldn't help but spit out blood, only to feel a little smoother.

But this time also caused him some minor injuries, and his blood volume dropped by more than 30,000 points.

"Whew, haha, cheer!" Xu Feng laughed.

"Be careful, it's a pity that you don't have a book that uses thunder and lightning to temper your body, otherwise, the progress will be much faster." Little Q said.

"Hehe, it doesn't matter, even if there is no exercise, it doesn't prevent me from tempering my body with thunder and lightning, it's just that the speed is slower." Xu Feng said with a smile: "But now the first thing is to find a place to live, I can't sleep in the open air and be bombarded by these thunderbolts." ”

"It's rare to find a place to live, and there are a lot of abandoned mines here, so you just need to clean it up a little." Q said, unfolding the scanner and scanning around.

"The gravitational force here is about 3.6 times that of the Earth, the density of the atmosphere is too great, and there are a lot of impurities in the air, which seriously limits my scanning range, and now I can only scan the range of 1,200 meters." In the communicator, Xiao Q's eyes flowed with light blue data, and he analyzed them one by one.

"In the area I scanned, there are a total of sixteen mines, all of which have been abandoned, of which thirteen have collapsed, and only three are relatively well preserved, eight hundred meters to the southeast, which is the closest mine to us."

Xu Feng nodded, just as he was about to rush towards the southeast, he suddenly frowned slightly, as if he sensed something, glanced behind him, and immediately changed his face, and swept towards the southeast as if he was fleeing.
