The broken wood looked like just an ordinary piece of wood, brown and black, with an extremely common fracture, and if it hadn't happened to come across it, I'm afraid no one would have connected the two things.

"Hey, what did you pretend to be, I knew I should have asked the boss for specific details. Li Chen sighed, when he was in the market in Fangzhong, the boss who sold this piece of wood said that he got it from the thunderstorm area, but at that time, in front of Lemi, he met the people of the Jiang family again, and he didn't ask much with a face, so he wanted to know more now, but he didn't know where to start.

"You can ask me for details. Xie Du didn't know how long to open the door, and looked at him with a smile at the door, "Fortunately, something has come to you, otherwise you want to know that it will take a long time, why didn't you take it out earlier." ”

Li Chen turned his head and heard what Xie Du meant, so he asked, "What, are you leaving?" When he said that he was leaving, he naturally meant that Xie Du set off for the Qingyi Empire, and he would have to go sooner or later, but he didn't expect to leave in such a hurry, and after careful calculation, he only arrived in Sunset City last night.

"You are in a hurry, I am also in a hurry, I will set off early tomorrow morning, as for here, I asked Bai Luo to stay and take care of Zhong Yuanshan. Xie Du closed the door with his backhand, and then locked it tightly, only to see that the star power instantly formed a circle of light, enveloping the entire room.

"What are you doing here?" Facing Xie Duan's actions, Li Chen asked suspiciously.

"Of course, I'm telling you about this piece of Lei Yin Jiamu, and it won't do them any good for the other people here to listen to it, so I'll cut off the sound. ”

"Lei Yin Jiamu?" Li Chen shook the broken wood in his hand, "That's what you said?"

Xie Du nodded, and then there was a lot of brilliance in his eyes: "You are so lucky, you actually got a piece of Lei Yin Jiamu, I'm afraid there are not many Lei Yin Jiamu in this world." ”

Li Chen looked at this piece of broken wood, and looked at it for a long time, but he really didn't find anything special about it, the lines on it were messy, and it could even be said that it was worse than ordinary wood.

"I can't tell what's so good about it no matter how I look at it......"

"That's because you don't know the story behind this piece of wood. Xie Du said as she thought about the information she had looked up before.

"Do you remember the master of the cave that the fifth brother told you before?"

"Could it be that this Lei Yin Jiamu has something to do with him?"

If this is the case, then it can only be said that there is no coincidence that the book is not written, and Xie Du and they are now investigating this matter.

"Sort of, when I heard the owner of the treasure map tell me about the strong man's past, I also went to check his information for a while, although it was not complete, but it was more than enough to explain this piece of Lei Yin Jiamu. ”

Xie Duan paused and said: "Speaking of this piece of Lei Yin Jiamu, I have to talk about the Thunder Xuanfu, when the one broke through the bottleneck, it happened to be in the center of a thunder and lightning storm, when the thunder gong danced wildly, the electric snake was swimming, and the area within a radius of hundreds of kilometers was full of thunder and lightning, and ordinary people would be bombarded and killed as soon as they entered." ”

"That area is still there, and it is also within the territory of the Scorching Sun Empire, but it has been completely deserted, there is nothing but thunder and lightning, and there was something back then, in the center of that area, there is a towering tree, the trunk is black, the branches are brown-black, it has stood in that area for thousands of years, even if it is subjected to tens of thousands of thunder and lightning impacts a day, it is still flourishing, and there is no damage at all. ”

Li Chen's heart became more and more surprised, there was such a magical tree in the world, which experienced thunder and lightning without injury, listening to Xie Duan's tone, it seemed that this thunder sound tree was a part of the towering tree.

"What happened?

Facing the curious Lichen, Xie Duan continued to smile and said: "The reason why the thunder sound tree can withstand the impact of thunder and lightning is because he has resistance to thunder and lightning, and can convert the power of thunder and lightning into sound wave impact to compete with thunder and lightning, and then the strong man sat quietly under the tree for a full seven hundred and forty-nine days, and used two thousand ethereal stones to contact with the thunder sound tree, the ethereal stone itself has a sound wave impact, this contact, it swallowed up the sound wave impact in the trunk of the thunder sound tree, and in less than a day, the tree was blasted into countless pieces by the thunder and lightning, and it was submerged in the yellow sand. ”

Hearing this, Li Chen laughed: "This master is quite lacking in morality, people stand there motionless, he has to go in and intervene, and make people go in and destroy them." ”

Xie Wei nodded sympathetically, and then said: " If it weren't for this, he wouldn't have comprehended the thunder talisman, as soon as the thunder sound tree disappeared, he was attacked by the thunder and lightning so that he almost didn't carry it, and in the end, he had no choice but to gather all the stumps of the thunder sound tree together, and use the characteristics of the ethereal stone again to absorb the power of thunder and lightning with the stumps, and the ethereal stone devoured the impact of the sound wave to form a temporary thunder sound tree, and finally, according to the mystery hidden in the thunder and lightning, he tried again and again, and finally drew twenty-seven runes, and he gradually merged with the power of thunder and lightning, rampant in that area。 ”

Later, after being poisoned by the blood corpse, he knew that his time was short, and he didn't want the Thunder Talisman to be lost, so he went to that area and planted all the fragments of the Thunder Sound Tree with a memory of his own, as long as he used the power of thunder and lightning to activate any of the Thunder Sound Trees, and then combined with the Ethereal Stone, he could enter the Thunder Sound Wood and carry out the thunder trial. ”

"Thunder Trial?" Li Chen said in shock, "Could it be that every Xuan Fu has to go through a trial before learning?"

Xie Du said: "That's natural, if you give up the trial and study directly, if you can't learn it, you will be killed by the characteristics of its Xuan Fu first, and only by increasing your corresponding resistance to more than ninety percent in the trial will you not be counterattacked by learning the Xuan Fu." ”

Li Chen's heart moved slightly, it turned out that this piece of broken wood still had this effect, I had heard Jun Qizhen say the so-called frost trial before, only those who have gone through the frost trial have the opportunity to learn the frost talisman, at that time he didn't think so, thinking that the academy deliberately fooled everyone in order to limit the number of frost talisman learning places, but he didn't expect this trial to be so important. ”

"Is this resistance really so heavy?" thought to himself, and now he still didn't know anything about resistance.

Xie Duan looked at Li Chen's expression, thinking that he still didn't understand something, and said: "In the process of cultivation, everyone's body has different resistance to various attributes, when you used the Ice and Fire Palm at the Moyang Festival before, did you also suffer different degrees of backlash?"

Li Chen thought about it for a while, while releasing the Ice and Fire Palm before, although the power was amazing, he was also a little uncomfortable with the conversion between ice and fire, and at the time he thought it was caused by the lack of star power, and then he thought about it again when he summed it up, it was indeed that he couldn't withstand the impact of the attributes of ice and fire, but fortunately, it was the star order he cast, and he had some protection mechanisms for himself, if he just suffered the temperature of ice and fire at that time, he might not be able to be made of something.

"Each attribute has different strengths and weaknesses, just like some fires can melt dark iron, while some fires can only ignite firewood, fortunately, the Ice and Fire Palm is not the top grade in the Silver Star Order, otherwise you haven't attacked others yet, and you're afraid that you will fall first. ”

"Before the Five Elements Order, the resistance of people to all objects was only three to ten percent, of course, this can be improved in other ways, but the effect is far less than the special trial, just like the thunder trial, once the trial is passed, the body's resistance to thunder and lightning can reach more than ninety percent, if you are lucky, more than one hundred percent is possible. ”

"And what if you don't pass the trial?

"Yes!"

"What's the difference between that and learning the Xuan Fu directly..."Li Chen just asked casually, but he didn't expect to be stunned in exchange.

Xie Du said: "The trial is just a way to exercise your corresponding resistance, if you can't bear it, you can quit, but it is different to learn the Xuan Fu directly, after the nine runes, each rune will have to bear the backlash of the attribute, there is no way back at all, if the attribute is too low, when you just start to draw the tenth rune, you will die instantly, and it is possible that there will not even be scum left." ”

After listening to what Xie Duan said, Li Chen moved his throat, and there would be no scum left, and just these few words formed a scene in his mind where he was devoured by the Xuan Fu.

Xie Duan said with a smile: "It's a pity that these Lei Yin Jiamu have been discovered after so many years, and now it is a great miracle to be able to get a piece." If there is no trial, even if it is said that Li Chen has a share, it is just an empty word.

Raising the Lei Yin Jiamu in his hand, Li Chen's eyes were full of surprise, in this way, if he could enter the cave in the future, he might be able to get the Thunder Talisman himself, and it would be full of energy to think about.

"It seems that we have to find a way to activate it with the power of thunder and lightning, so that we can go in and give it a try, I don't know how difficult it is. ”

"Well, I happen to have a star order with a thunder attribute attached to it, and you give me the wood and I'll activate it. ”

"Uh, that's okay?"

"What's wrong with this, my thunder attribute resistance is higher than yours, and the power of thunder and lightning can be used to activate it. ”

Li Chen nodded suddenly, then handed the piece of wood to Xie Du, rubbing his hands excitedly, the first time he tried it, his heart was full of novelty.

Just as Xie Duan took out the Silver Star Order, he suddenly said again: "Wait a minute, since this piece of wood is so precious, it is better to call more people to come, and try it together, otherwise it will be a waste." ”

When Xie Duan heard this, he said leisurely: "It's useless, a piece of Lei Yin Jiamu can only allow four people to try, and each person can only test once, we got one before, and handed it to Bai Luo and them to try." ”

"The result?"

"It's all failed!"

"Damn!" Li Chen couldn't help but gasp, "This failure rate is too scary, and the four of them failed together." ”

"Otherwise, although we have comprehended the power of the five elements, we have only increased the resistance of one of the attributes to one hundred percent, and the power of the five elements only represents gold, wood, water, fire, and earth, and the thunder attribute is not included in it, so failure is a normal thing. ”
