Lin Xuan is now a swordsman who has broken through the realm of sword souls, and his strength is not trivial. He had already tried the thickness of this iron door just now, and he had a bottom in his heart, and he had secretly made a prediction. But now the truth is not at all what he imagined, and it really surprised him.

In fact, it wasn't just Lin Xu who was surprised, even Wang Lung was the same. Wang Lung couldn't help but blurt out immediately: "Strange!"

"Wang Lung, what do you think is strange? Lin Xuan turned his head and asked Wang Longdao.

"Big brother, just now you slapped such a powerful palm towards the middle of this door, even if you can't open this iron door, then it will at least have some shaking from the gap in the middle, and it is impossible not to move without moving. Wang Lung seriously told Lin Xudao the doubts in his heart.

"That's right, you and I thought about it. That's what I find particularly odd about this door. That palm just now was my temptation, and it seems that I can't open it with brute force. Lin Xuan nodded and said thoughtfully to Wang Lung.

"Could it be that this iron gate is not only made of iron, but also has other stronger materials added to it, which is why it is so solid that even a high-level swordsman like you can't shake it?" Wang Lung asked Lin Xudao in a speculative tone. He didn't know if he was analyzing it correctly or not, but saying what he thought in his heart could always broaden Lin Xu's thinking.

"I don't think it's a matter of materials. Its oddity is no longer just a matter of materials. Lin Xuan thought as he said to Wang Long: "No matter what this iron door is made of, no matter how hard the material is, but there must be a gap between this kind of door that is divided into two doors, it is impossible to completely join together. ”

Lin Xu said, and reached out to grab the two huge knockers on the iron door and shook them, and suddenly made a "clanging" sound, as if urging Lin Xuan to hurry up and find a way to open the iron door as soon as possible.

"That's right, big brother, since there is a gap in the middle of the iron door, under the impact of your palm, it should be dynamic. Even if it doesn't wobble significantly, there should be a slight shaking. Just now, he was motionless, which is really incomprehensible. Wang Lung sighed and said to Lin Xu.

Wang Lung felt that Lin Xu's analysis was very reasonable, but it couldn't make him think of a way to open the iron door, so he couldn't help but feel a little discouraged.

Suddenly, Lin Xuan seemed to have figured it out, looked at the tall iron gate in front of him with bright eyes, and said to Wang Lung: "Could it be that there is no gap in the middle of this iron gate at all, so it will be so strong?"

"There is no gap?" Wang Long was extremely surprised when he heard Lin Xu's words, and he also felt particularly incredible. He pointed to the two iron rings on the iron door and said to Lin Xu: "This kind of door is divided into two doors, left and right, even if it is closed, there must be a gap in the middle." And there is obviously a thin straight line in the middle. ”

"I think it's all an illusion, it's used to deceive people. I suspect that this iron gate is a thick iron plate, and there is no separation between the left and right sides at all. We were all deceived by it just now. Lin Xuan said to Wang Lung seriously.

Lin Xuan immediately pulled out the sword, and scraped it down vigorously along the straight line that looked like a crack in the middle of the two gate rings on the iron gate, scraping all the rust on it, and then he could see the stripe more clearly.

As the rust covering the lines was cleared by Lin Xu, the lines that were originally hidden under it could be seen very clearly. As Lin Xuan expected, this pattern only looks like a gap on the surface, but in fact, it is not, it is just a pattern artificially drawn in the middle of the iron gate.

Wang Lung had already seen it clearly. He couldn't help but be even more surprised and said, "Big brother, it's really like you said, this is not a crack." The iron gate was not divided into left and right sides at all, but in one piece. But does that mean we'll never be able to open this iron door?"

After Wang Lung saw the iron gate as it was, he found a new problem, and he felt even more frustrated and disappointed. If they can't open the iron gate, then they will never know what secrets are hidden behind the iron gate.

"Let's take our time, I don't believe it can't be opened. Lin Xu is very confident, and it can be said that it is diametrically opposed to Wang Long's performance.

Lin Xu then instructed Wang Long and the soldiers to clean all the rust on the iron gate, so that he could see the iron gate more clearly.

After looking at it several times, he finally noticed a special place to the right of the iron gate. He tapped its surface a few times, and finally heard a few crisp sounds, rather than the muffled sound he made when he banged on the rest of the iron door. This means that the thickness of this place on the iron gate is much thinner than the rest.

"There's a small door here!" Lin Xuan finally discovered the secret on the iron door, and announced loudly with great joy.

When Wang Lung and the soldiers heard this, they also became happy with Lin Xu. They believed that Lin Xuan would definitely have a way to open this iron gate.

Lin Xuan first used his sword to draw the approximate location of what he thought was the small gate on the iron gate, and then ran his true qi, gathering all his true qi on the sword, just like sending an attack on the enemy, he used all his strength to slash out a sword, and used the blue ice slash move.

"Bang-"

The small door installed on the iron door was finally hit by the powerful power of the blue ice slash used by Lin Xu, and it was dented inside. Although it had not yet been fully opened, the four edges of the small door had been completely revealed, allowing Lin Xuan and Wang Lung to see the specific location of the small door.

"Haha! it worked!" Wang Lung couldn't help but cheer at first. When the other soldiers heard this, they immediately joined him in laughing.

Wang Lung stepped forward to help Lin Xuan push the small door hard, because the small door was also made of fine iron. The rubbing between iron and iron produces a "squeak" sound that sounds particularly sharp and harsh.

A crack slowly formed between the small door and the iron door. This is the real crack, not a fake crack like the one in the middle of the iron door.

As Lin Xuan and Wang Lung pushed, the crack slowly grew larger and became a big opening. In a few moments, it had become the width of a person's body, that is, enough for a person to walk through this opening.

Due to the fact that there was too much rust on the small door, and Lin Xu's blue ice slash just now also destroyed the integrity of the small door, it was impossible to completely open this small door. But Lin Xuan felt that as long as he could pass through this tall and heavy iron gate, he didn't need to make any effort to open the small door completely.

So, Lin Xu asked Wang Lung to stop immediately and not push anymore.

Lin Xuan looked at the small door that was already half-open, and said with a triumphant smile: "Hehe, it turns out that there is still a door in the door, no wonder we have to work so hard to open it." ”

"Big brother, thanks to your cleverness, otherwise we would not have discovered the secret on this iron door and successfully opened this small door. Wang Lung was sincerely impressed by Lin Xuzhen, so he praised him.

Lin Xu took a torch from a soldier's hand and said, "I'll go first to inspect it, and if there is no danger, I'll call you in." ”

"Big brother, then you should be careful yourself, and if you find something wrong, quit immediately. We were able to keep the door safe by closing the door in time. Wang Lung said to Lin Xuan seriously. He was just worried that there were some monsters such as mountain monsters or demonic beasts that would threaten Lin Xu. Although Lin Xu's martial arts cultivation is very high, it is always better to be careful when sailing a 10,000-year-old ship.

"I see, don't worry. Lin Xuan nodded, then held the torch and walked in through the half-open small door.

Lin Xuan found that behind the iron gate was a wide open space, and did not find a monster that could threaten humans. He took a closer look at the ground, and felt that there would be no traps or anything like that, so he walked in a little bit of relief.

Before he could walk far, Lin Xu was shocked by the scene in front of him. Of course, this shock contains more of a surprise. For three feet in front of him was sprinkled with gold coins, making the road ahead seem to be paved with gold coins.

Although before entering this cave, Lin Xuan estimated that there was a treasure buried here, but at that time, he was more of a joke and didn't take it seriously in his heart. Even if there is no treasure in the cave, he will not be disappointed.

Now that Lin Xu saw the gold coins all over the ground in front of him, and knew that his joke had come true, he really felt very happy and shocked. He wasn't a particularly money-hungry man, but there was no one who didn't like this yellow gold coin, and he certainly wouldn't be an exception.

At this time, Lin Xuan was not far away from Wang Long and the soldiers who were waiting outside the iron gate. All he had to do was shout loudly, and Wang Lung and the soldiers could hear him. So he didn't have to go back, he just shouted loudly on the spot, "Wang Lung, brothers, come in." There's a lot of gold waiting to be picked up. ”

"Is it real?" Wang Lung heard Lin Xu's shout, so he happily led the soldiers through the small door on the iron gate and walked in quickly. As soon as they heard that there was a gold coin, they were all very excited and rejoicing.

When Wang Lung and the soldiers came to Lin Xu's side and looked forward, they almost couldn't believe their eyes, they really saw gold coins all over the ground. They had to admit that they had never seen so many gold coins.

"Ahh

But none of them were in a hurry to rush over and grab the gold coins. Before Lin Xu gave an order, they would never act rashly. Even with the temptation of so many gold coins in front of them, they were able to resist it, and always remembered to obey the rules of the kamikaze camp. This shows how successfully Lin Xuping taught them in peacetime.
