Lin Xiu couldn't laugh or cry at the big characters that appeared on it, because besides the big characters of Thunderbolt written on it, there was a row of small characters beside it.

"Don't learn unless you are ridiculous... What the hell is this!"

Lin Xiu also quickly opened the exercise, but it seemed that he could only open the first page, and there seemed to be something missing in the back, and he couldn't open it at all.

"You need to collect polar mines to open them, and if you want to learn, you must be able to withstand the lightning strikes of polar mines." Lin Xiu saw here and realized why there were words on the front cover that you must not learn.Seeing this, Lin Xiu couldn't help but feel a little happy. Who is Lin Xiu, a man who can't be shaken by double thunder calamities, so naturally he is very confident in facing this extreme mine.

"However, what exactly is this polar mine? I've never heard of it before. Let's ask Immortal Taixu first. He should know the location of this polar mine because he is well-informed."

Lin Xiu also hurriedly found Immortal Taixu, but he didn't expect to be scolded as soon as he came up.

"Hey, isn't this our hero Lin Xiu, who challenged the teacher in public and left the school, isn't that bad?" Apparently, as the leader of this Taixu Academy, he left without telling Lin Xiu The academy also felt a little angry.

"Immortal, I was wrong. I should have told you first. I was too anxious at the time."

"Okay, since you have brought such a good seed as Ruoxin to our school, I won't bother with you. But if something like this happens next time, I don't care who you are, I will come to you directly Excuse me, do you hear me?"

"Yes, Immortal, I came this time to ask you something."

"Tell me, it's still a secret with me."

"Excuse me, Immortal, do you know such things as polar mines?" Hearing Lin Xiu say the word "polar mines", the tea in Immortal Taixu's mouth was about to spit out.

"Why do you ask this? That thing is very dangerous." It seems that the Taixu Immortal also knows the existence of this polar mine, but this thing seems to be very dangerous, otherwise the Taixu Immortal would not have such a big mine reaction.

"Students have a book of exercises that needs the blessing of this extreme mine. So even in danger, students have to find it."

"Well, you kid, this polar mine is a kind of lightning that can only be produced under very special conditions. It is special because ordinary lightning is produced at normal temperature, but this polar mine is produced under very special conditions." Thunder and lightning can only be produced at extremely low temperatures. And precisely because of this, the power of this polar mine is much greater than that of ordinary lightning."

"Then where can I find this pole mine?"

"It is said that in the north of our Taixu Academy, there is an extremely cold place. The temperature here is terribly low all year round. I speculate that there should be polar mines there."

"Okay, thank you Immortal, I will set off tomorrow to find that extremely cold place."

"Let me remind you, there may be polar mines there. Because the temperature is too low, the creatures there are all mutated creatures with extremely strong fighting power, so you must be careful yourself, and you must come back alive to listen to me. Is it there?"

"Well, don't worry, I'm Xiaoqiang who can't be beaten to death."

"Okay, try to go and come back as soon as possible, the final exam is coming soon, you can't be absent. This exam will be watched by the Jade Emperor in person, you have to give me a little bit of care, maybe I don't want the Jade Emperor to fancy it Now, wouldn’t it be a pleasure to find you a half-time official in this Heavenly Palace.”

"Thank you Immortal, then I will take my leave first." In fact, Lin Xiu was not interested in joining Tiangong, because he had seen gold and silver generals who would only use their official positions to bully ordinary people like this before, so he was not interested in joining Tiangong. The impression of Tiangong was not very good.However, if the Jade Emperor can come, he might be able to get the blood of the Immortal Emperor from him. This is what Lin Xiu is most interested in at present.

The next day, Lin Xiu also said goodbye to the pair and Ruo Xin early, and was about to set off to find the pole mine.

"What? You're going to an extremely cold place. You know how terrifying it is. It is said that many immortal kings and even emperors perish there every year." Shuang'er had also heard about this extremely cold place from others before. things in cold places.So when he heard that Lin Xiu was going to an extremely cold place, or going to find the polar lightning strike, he was naturally very worried.

"No way, if you want to cultivate this thunderbolt, you must go through the body training of this extreme mine, so in order to become stronger, I still have to go there." Lin Xiu also understands that people only value how strong you are, not how strong you are. I care too much about how you become stronger, but often the process of becoming stronger is the most important thing.

"Okay, but you must come back alive for me."

"Sister Shuang'er, I want to visit such an exciting place." Obviously, Ruoxin is not an easy-going lamp. Hearing that this place is dangerous, the more he wants to know more about it.

"You think you can go if you want, you just stay in this Taixu Immortal Mansion honestly, or I will take good care of you when I come back."

"No, I'm going, I'm going, or I'll sneak out."

"Okay, I've convinced you, grandma, you stay here in Taixu Academy, and I'll teach you how to make medicine when I come back." Lin Xiu saw that the threat was useless to Ruoxin, So it is only a soft grinding method.

"That's about the same. What you taught me last time is no longer enough. I want to learn something new. Don't lie. Sister Shuang'er, you are our notary. "

"Okay, I will remember." Shuang'er also looked at Ruo Xin helplessly, she looked like a teenager on the outside, but she was like a child on the inside.

Chapter 1473 The Might of the Extreme Thunder

Seeing that Ruo Xin finally stopped clamoring to go with him, she felt a little relieved.He didn't dare to bring this Ruoxin by his side, if something serious happened, not to mention that he felt sorry, even Immortal Taixu would definitely trouble him.

"Shuang'er, I'm leaving right away. You and Ruoxin should be careful when staying in Taixu Academy, I'm afraid that the dark demons will come out and trouble us again." Before that, Li Shang's family was involved with the dark demons, Lin Xiu was afraid that the dark demons were secretly tinkering with something else.

"It's okay, I'm not a child anymore, I still care about this and that all day long. You should go quickly, otherwise if you miss the final exam, you will be scolded." Shuang'er is also superficially annoyed, but don't mention it in her heart. What a joy.

"Ahem, please stop showing off in front of me, you two, I still have to eat."

Ruo Xin's words also made the two of them couldn't help laughing.

Lin Xiu also stopped talking, and went directly to the north.

Sure enough, the further north he went, the lower the temperature became. Lin Xiu also felt bursts of cold air entering his body unconsciously, which had somewhat blocked the flow of energy in his body.Lin Xiu also hurriedly mobilized his own energy.Most of the cold air in the body was driven away.

After flying for a while, Lin Xiu finally seemed to see the place he was looking for, because a large ice field appeared in front of him.

Immediately, everything before Lin Xiu's eyes was a vast expanse of whiteness, and there was a dead silence everywhere, as if there was no living thing here except the ice and snow.

"You can't come to the wrong place, it's ice besides the damn ice." Just when Lin Xiu thought he was in the wrong place, the book Thunderbolt in his pocket suddenly reacted.

I saw this thunderbolt quickly flew into the air, and I automatically opened the page.Suddenly, the sky changed drastically, the sky suddenly became cloudy, and a thunderbolt struck directly.Fortunately, Lin Xiu reacted quickly enough, otherwise he would have been seriously injured by electric shock or something.

What Lin Xiu didn't expect was that it was just the beginning.A streak of cyan lightning also struck directly from the sky.However, Lin Xiu was surprised to find that the main target of these thunders and lightnings seemed not to be him, but the book Thunderbolt in mid-air.

All the thunder and lightning were directly absorbed by the Thunderbolt, and gradually, every time he was shocked by an electric shock, the Thunderbolt book turned a page again.

Finally, after half an hour of electric shocks, the entire book began to glow with thunder.

"It should be over." Lin Xiu also wanted to jump into the air to get the book back after watching the lightning finally stop flashing.

The silent sky began to show its power again, this time it was stronger than last time, tens of thousands of thunder and lightning trapped Lin Xiu alive like a cage.

"It's really going to surround me and hit me." Because Lin Xiu found that as long as he moved, the next thunderbolt would definitely hit its feet.

In the next second, a huge thunderbolt directly charged towards the top of Lin Xiu's head, and the huge current directly spread throughout Lin Xiu's whole body.Lin Xiu also quickly used his Qibao Linglong Pagoda to directly absorb most of the lightning in his body, but a small part remained in Lin Xiu's body.

If someone can clearly see what's going on in Lin Xiu's body, they will find that almost every meridian in Lin Xiu's body has a little bit of lightning beating.Lin Xiu also felt bursts of severe pain coming from his body.

Lin Xiu's whole body was covered with lightning, which looked very frightening.As a result, another huge thunderbolt struck Lin Xiu directly.

Lin Xiu, who had been suffering physically, suffered another heavy blow, and was directly knocked down to his knees. This time, even the Seven Treasures Exquisite Pagoda couldn't absorb it.Because the Seven Treasures Exquisite Pagoda also has its own load capacity, and if it exceeds it, it will be directly exploded.So Lin Xiu didn't dare to release it outside.

"It seems that I can only rely on myself." Lin Xiu also activated his Arhat Immortal Body, which greatly improved his physical strength and made himself more resistant.

Lin Xiu also had a premonition that the real storm didn't really come until now.Sure enough, one lightning after another struck Lin Xiu mercilessly.Soon there were scorched marks all over his body, and his clothes were directly burned off.

But Lin Xiu didn't give up yet, the thunderous shot he took so hard.It can't be abandoned without cultivation, so he has been persisting with perseverance.

A thunderbolt struck Lin Xiu's already overwhelmed body, directly knocking him out.At this moment, another bolt of lightning strikes him, but what is strange is that a huge protective shield made of lightning suddenly appeared on Lin Xiu who had already passed out, directly blocking the lightning.

After being in a coma for more than half an hour, Lin Xiu also woke up from the coma.He was surprised to find that the book had returned to him, but all the words in the book disappeared miraculously.

"Oh my god, my headache is killing me." Lin Xiu carefully examined his physical condition with mental strength, and found that all the injuries on his body had been repaired, and his physical body seemed to be stronger than before. Not a lot.
