The young man beside the black-clad warrior heard Lin Ming's refusal and muttered under his breath, "He really doesn't know what's good for him. Eldest Brother is willing to take him in because he thinks highly of him, but he still refuses. He's just waiting for death."

  Although the young man's voice was not loud, Lin Ming's ears were sharp and his eyes were bright, so he naturally heard it clearly. He had suppressed his cultivation to the initial stage of refining the marrow, firstly out of caution, secondly because he didn't want to attract attention. After all, at his age, reaching the peak of bone refinement was too astonishing.

  After all, these five martial artists are hiding in a small place, having never seen the world and not knowing how many geniuses there are outside.

  Those twin girls seemed to be unable to bear Lin Ming being sent to his death, and opened their mouths to say: "Little brother is coming to Thunder Mountain for the first time, right? This isn't a place where you can just play around, after passing through the outer forest it's danger upon danger, even Foundation Building stage warriors basically can't survive. If we didn't have big senior brother leading us, we wouldn't dare come either. We won't charge you much money, when out and about, having more friends is always good."

  Lin Ming heard the twin sisters' tone and was a bit speechless, actually saying that this place wasn't for casual play, as if there were people who came to Leishan Mountain specifically for tourism.

  The black-clad warrior saw that Lin Ming did not respond and said, "Let him be alone, we'll leave."

  He had originally wanted to make some extra money, but since the other party didn't know a good thing when they saw it, he might as well forget it. Just as he was about to leave, Lin Ming suddenly spoke up and asked, "Do you have any of last year's Thunderbolt Grass? I can buy it from you at market price."

  He waited patiently for those guys to deal with the fierce beast, just wanting to ask if there was any aged Thunderbolt Grass, he could try it out and see if this Thunderbolt Grass was worth picking himself.

  Lin Ming's question made the black-clothed warrior feel strange in his heart. Could it be that this person was cultivating thunder attribute true yuan? Why would he want to buy Thunderbolt Grass?

  Or was he buying for some tribe? Even if a tribe bought Thunder Grass, they wouldn't send a little kid to collect it.

  The man in black hesitated for a moment and asked: "How many years' worth do you want?"

  Lin Mingdao said: "The higher the year, the better, and the price is given to you."

  Lin Ming said, the black-clothed martial artist next to Yi Jin's early-stage martial artist suddenly lit up his eyes and quietly transmitted a voice with his true yuan: "Big Brother Master, this little guy has a big tone, seems to be quite rich."

  The black-clothed warrior ignored the young man and said to Lin Ming, "Two Thunderblaze Grasses from 90 years ago, three hundred taels of gold, do you want them?"

  The price of three hundred taels of gold was slightly higher than the market price, but Lin Ming didn't mind, and with a flick of his wrist, three golden tickets flew towards the black-clothed warrior.

  "The gold voucher of the United Chamber of Commerce can be exchanged in the Great Tribe or Tianyun Country."

  The black-clothed warrior took the golden ticket and looked at it, and indeed it was a golden ticket from the United Chamber of Commerce. He took out the Thunderbolt Grass from his backpack and threw it towards Lin Ming.

  Lin Ming took it and glanced at it, confirming that the year was correct, then left without looking back.

  The black-clothed warrior saw Lin Ming wipe the Thunderbolt Grass off his ring with a light touch, and a sharp glint flashed in his eyes. He hesitated for a moment before letting Lin Ming leave.

  Until Lin Ming disappeared, the young man who was initially easy to get along with grumbled: "Big Brother Master. That guy just now was obviously a fat sheep, with at least 1,800 gold on him, and you let him go like that? In my opinion, we should have robbed him directly. If he didn't know what's good for him, we would..."

  That young man made a neck-stretching motion, and the black-clothed warrior gave him a white eye, saying: "A thousand eight hundred taels of gold? Do you think that kid is so simple? That kid has a Xumi ring on his hand! This thing our master can't even handle! A thousand eight hundred taels of gold are probably just a meal to him!"

  "Must... Must be a joke?" The young man was stunned, "No way. He actually brought this kind of thing? Then why would he come to a place like Thunderbolt Mountain, where you risk your life and can't even make much money? Why would those rich kids come here?"

  "Looking for Lei Feng Cao, but I don't know what use he has for this thing."

  The young man suddenly realized something and hastily said, "Big Brother Master, he's wearing a Sumi ring, it's worth tens of thousands of gold. If we rob him, we'll be set for life!"

  "Damn you!" The black-clothed warrior gave the young man a burst of punches. "He must be from a major sect or a big family. People like him have many treasures on them, and they're also hard to deal with. If we can't keep him, we'll be dead for sure. He doesn't look like an idiot either, coming to challenge the Thunderbolt Mountain at the Refining Stage. Who knows what kind of trump card he has to save his life."

  "Besides, we make a living with our skills, not by robbery. Be careful, the boat that sails for ten thousand years will eventually capsize in the ditch if you always think about killing people and stealing goods."

  The young man was scolded, and he looked somewhat unconvinced, pouting his mouth. He was still thinking about the tens of thousands of taels of gold on Lin Ming's body. In his opinion, a 15 or 16-year-old little kid, no matter how powerful, could not be that powerful.

  "But those twin girls asked strangely: 'Big Brother Master, what is a Mustika ring?'"

  "Haha, it's a spatial storage treasure, only the size of a ring, but can store several square meters of things. I'll get one to play with when I reach the Condensation Stage later, and show you guys then."

  "Really? That's great! With this thing, it'll be much more convenient for us to go out and collect materials in the future. We won't need to carry a backpack anymore." The two girls were extremely excited about this strange treasure.

  "Practicing to the Condensing Pulse stage and still trying to flirt? What a load of nonsense...” The young man in the Easy Tendon stage thought to himself as he watched the black-clad martial artist trying to impress the beauty, but of course, he dared not say it out loud.

  Ten miles away, Lin Ming sat on a rock, holding two Thunderbolt Fruit in his hand. The fruit was flashing with a faint thunder light, and after a moment, the thunder light dissipated, and the fruit also withered down.

  Lin Ming opened his eyes and threw away the withered fruit in a somewhat helpless manner.

  Ninety years ago, the Thunder Grass was nothing more than this. It had some effect, but it was really too small. I'm afraid that even if you absorb a few thousand fruits, the growth of Leiling's power won't exceed 10%.

  Not to mention collecting thousands of fruits is time-consuming and laborious, the key is that the promotion of Thunderbolt Grass to Thunder Spirit cannot be sustained.

  Based on past experience, Lei Ling absorbs low-level lightning and quickly reaches saturation, unable to continue strengthening.

  But Lin Ming did not lose heart, before coming to Lei Ting Mountain, he had mentally prepared himself for the difficulties ahead. This mountain must have its opportunities, but true opportunities cannot be picked by just anyone, otherwise they would have been taken long ago, how could it possibly be his turn?

  According to the Thunder Mountain Manual, this Thunderbolt Grass can live for up to a thousand years. The fruit is purple in color. This thousand-year-old Thunderbolt Grass contains an unmatched powerful force of thunder. If we can get a few plants, it should be able to help Leiling grow some more. Unfortunately, this thousand-year-old Thunderbolt Grass is too hard to find.

  Leigong grass can grow for thousands of years, up to one thousand or even two thousand years, but over the years, countless warriors have entered and exited Leigong Mountain. Fifty-year-old Leigong grass has long been picked clean, how could it be left to grow for a thousand years?

  To find the Millennium Thunderbolt Grass, it can only be found in places near the top of the mountain where people rarely set foot.

  However, once beyond the mountain waist, even a postnatal warrior must be careful, Lin Ming has Lei Ling on his body and has strong resistance to thunder and lightning, but he also dare not go too deep.

  Lin Ming was deep in thought when he suddenly heard a loud and shrill beast roar coming from behind him, like the sudden clap of spring thunder, shaking the heavens.

  Then there was a scream, Lin Ming could tell that this scream came from one of the people who were just there.

  He suddenly got up and rushed to the back, according to the description of Leiting Mountain's booklet, this beast with a roar like spring thunder was mostly a Thunder Lizard.

  Lin Ming had long wanted to see this Thunder Lizard, and after entering the Thunder Mountain for so long, he finally encountered his first one.

  He wants to know if he is afraid of the lightning spit out by the Thunder Lizard, so as to infer how high he can climb on the Thunder Mountain.

  Also want to know, can Thunder Lizard become a supplement for Lei Ling, whether it is worth his shot.

  Lin Ming unfolded his body technique, his figure flashing like lightning. Because of the extreme speed, the surrounding scenery seemed to distort and twist.

  Within a distance of ten li, Lin Ming arrived in just over a dozen breaths. Before his eyes was a gigantic ferocious beast covered entirely in pale red scales, its body somewhat similar to that of a lizard, but with a higher back and bulging giant bony plates all over, looking more like a dragon than anything else.

  At this time, in front of the giant lizard, four people stood there with terrified expressions. They were the so-called Master Brother, a peak warrior at the Easy Muscle stage; twin sisters at the initial stage of Refining Marrow; and a youth known as Little Dragon, also at the initial stage of Refining Marrow.

  As for the young martial artist who was practicing qigong at the beginning, he had already turned completely black and fell to the ground, apparently having been struck by lightning. Although he still had a breath of life left in him, it seemed that he wouldn't be far from death either.

  As the senior brother of the black-clad warrior, his face turned pale. He could clearly feel that the Thunder Lizard had locked onto him and would face a lightning attack as soon as he made a move!

  "Damn it! How unlucky, at this height there shouldn't be a Thunder Lizard equivalent to the peak of Bone Forging!"

  The black-clothed warrior was secretly lamenting, being stared at by the Thunder Lizard, he didn't even dare to breathe heavily. The other three young men and women were almost in despair, even Second Master was severely injured after just one exchange, they three weren't even enough to fill a gap between teeth.

  Just then, the Thunder Lizard suddenly let out a low growl, sensing something. It slowly turned around and saw that behind it, a young man had appeared at some point, holding a narrow knife and standing casually in the grass.

  Although this young man didn't have any aura about him, for some reason, he gave Lei Ting a feeling of extreme danger.

  "Is it him?" The black-clothed warrior and the twin girls only then discovered that Lin Ming had returned, "How did he come back? Could it be that he specifically came for this Thunder Frog?"

  The black-clad warrior realized this and felt a bit dizzy in his head, what was he going to do?

  Although he acknowledged that Lin Ming had some life-saving trump cards, the black-clothed warrior estimated that these trump cards were mostly used for escaping and never thought that Lin Ming's combat strength could deal with the Thunder Lizard at the peak of Tempering Marrow.
