Lin Xu waited until Wang Lung and the soldiers were far away before slowly opening the iron box again. In order to protect himself, he no longer faced the opening of the iron box as he had just done, but turned the iron box so that the opening was facing the stone wall of the cave. In this way, even if the iron box is really equipped with hidden arrows, it will not hurt Lin Xu.

"Whoa—"

The moment Lin Xuan opened the iron box, he heard this familiar voice again. But he soon discovered that it was not the sound of a dark arrow being fired, but the sound of a powerful light pouring out of the iron box and piercing the void.

The light that emanated from the tin box was not white, but a faint blue, but it was also very bright, almost blinding, illuminating the dim cave as bright as day.

The faint blue light exuded an extremely cold aura, which made the surrounding temperature drop a lot in an instant, as if it was a harsh winter in the blink of an eye.

For Lin Xu, this kind of cold air is nothing. Because he himself is an ice attribute, he has long been accustomed to this kind of cold aura when he usually cultivates the Blue Ice Heavenly Sword Duel. But for Wang Lung and the other soldiers, there was immediately a chill down their backs. Some soldiers with weaker physiques were so cold that they couldn't help fighting with their teeth and shivering all over.

They were still more than a foot away from Lin Xu, and they already felt so cold. If they stood beside Lin Xu, they would definitely be directly frozen by the cold air emitted from the iron box, and even cause internal injuries.

Lin Xuan opened the lid of the iron box completely, and it wasn't until after a while that the blue cold light slowly dissipated, and the temperature around him gradually rose, no longer as cold as just now.

Wang Lung and the soldiers were able to bear this, and no longer felt any discomfort, so they ran to Lin Xu's side with confidence and boldness, wanting to see what was in the iron box to satisfy their curiosity.

Inside the tin box is a copper plate engraved with strange symbols, as well as two small tin boxes and two porcelain vases. Lin Xuan was secretly glad that he had caught the iron box firmly just now. Otherwise, the two porcelain vases contained inside will definitely break.

The two small iron boxes may be due to the fact that they are the same size and shape, and there are numbers on the surface of the boxes, which are the No. 1 and No. 2 boxes. The two porcelain vases have no number, but one large and one small, which are easy to distinguish and will definitely not mess up.

The two lockets and the porcelain vase would not emit light, so the bright light emitted by Lin Xu when he opened the iron box just now must have come from the copper sheet engraved with symbols.

When Lin Xu saw this piece of copper, he couldn't help but be full of joy, and a smile full of surprise appeared on his face. Obviously, this piece of copper is extremely useful to him.

Wang Lung and the soldiers couldn't understand what was so special about the seemingly ordinary copper plates, at most they had some strange symbols engraved on them. If it is dropped on the main road outside, even if they see it, they will not necessarily pick it up. Because they don't know what it is, and they don't know what it's for.

"Big brother, what is this?" Wang Lung pointed to the copper sheet inside the iron box and asked Lin Xudao in a low voice.

"This is the sword talisman. Lin Xuan smiled and told Wang Long: "As long as you cultivate to the home, it can replace the sword in your hand to kill." ”

"Oh, I've heard of this sword talisman for a long time, but I've only had the opportunity to see it today. Wang Lung immediately understood, and then asked Lin Xu, "Big brother, with your strength now, can you carve this kind of sword skill talisman?"

"I don't have that skill yet. Lin Xuan told Wang Lung the truth and said, "The sword skill talisman needs to be able to be engraved with inscriptions. Although I have long wanted to cultivate the Inscription Technique, I have never had more time and energy to cultivate the Inscription Technique because I have to cultivate the Blue Ice Heavenly Sword Dueling and at the same time deal with the enemy's attack. But now, with this sword talisman, I can use it against enemies in the future. This is even more precious than the gold coins just now. ”

"I see, great, congratulations big brother. Wang Lung was also happy for Lin Xu, and congratulated him with a smile. This kind of high-level treasure can only be used by a high-level swordsman like Lin Xu. If it were given to Wang Lung or another soldier, they would only waste a treasure in vain.

"I really didn't expect this tin box to contain such a treasure, I was so lucky today. Lin couldn't hold back his joy, smiled and sighed, looking very excited.

"Big brother, there are two small boxes and two porcelain bottles, maybe the treasures inside are even more rare and precious. Wang Lung reminded Lin Xudao.

"Hahaha! Let's open it and see, if you can use it, I can give it to you. Lin Xu said with a hearty laugh.

This made Wang Lung and the soldiers look forward to it in their hearts. Of course, they hope that the treasures in the small box or porcelain vase can be used for their own use, and I believe that Lin Xu will definitely do what he says and give them away. It's just that they don't think it's very likely. Judging from that sword talisman, the treasure in this iron box is not something that ordinary people can use. If the contents of the lockets and vases were more advanced and precious, then Wang Lung and the soldiers were even more unusable. Because they haven't reached the corresponding realm and strength yet.

Lin Xuan picked up the No. 1 locket and reminded Wang Lung and the soldiers: "I don't know if there will be cold air in this small box, if it doesn't feel right, you can retreat immediately." I'll find a small gap to observe, and then slowly open it, and it should be fine. ”

"Yes, big brother, we understand. Wang Lung and the soldiers replied in unison.

Lin Xuan slowly lifted the lid of the small box and opened a thin gap, only to see that a bright light immediately radiated from the box, and it was no longer as cold as just now. Lin Xuan secretly breathed a sigh of relief, and opened the entire lid of the box with confidence, only to see a red bead in the No. 1 small box.

The bead is not big, only the size of three fingers, but its color is very bright red, like blood, which makes people feel that it is full of blood.

Lin Xuan couldn't make out what it was at first, so he put his hand into the small box and took the red bead directly in his hand. He immediately felt the energy released from the orb, which instantly warmed his palm. This is the opposite of the cold air released by the sword skill talisman just now, which makes people feel cold.

Lin was secretly surprised in his heart, feeling that this bead was indeed like a living being, and it could release the energy needed by human beings. And this energy was particularly strong, much greater than the energy contained in the Pure Body Pill he had taken before.

With great excitement, Lin Xuan put this bead in front of his eyes and looked at it carefully for a while, and finally recognized that this was an ice-attribute five-star magic bead based on the relevant records and descriptions he had seen in the secret books of ancient books before.

This kind of magic bead is refined with the magic core of a large number of high-level demonic beasts, which can be said to gather the most essential and useful parts of the demonic beast body, and concentrate the energy that originally belonged to various demonic beasts into one magic bead, which can provide a steady stream of energy for the cultivator of the sword.

The most special and precious point is that although the five-star magic bead also belongs to the category of pills, it is not like ordinary pills, which can only be taken once, but can be recycled. This shows how powerful it is.

"Hehe, that's another good thing. Lin said with a grin.

"Big brother, do you see what it is?" Wang Lung just now saw Lin Xuan staring at the magic bead for a long time, knowing that he was trying to identify it, and it was inconvenient for him to disturb him, so he didn't speak until this time.

"Of course I can see it. Lin Xuan smiled and told Wang Long, "This is a five-star magic bead, which can provide energy to cultivators and speed up the speed and effect of cultivation. If you can use this treasure, I'll give it to you. ”

As he spoke, Lin Xuan put the five-star magic bead back into the small box, and then handed it to Wang Long along with the box.

"Ouch, big brother, this can't be helped. You found and took down these treasures, they belong to you, and I can't ask for them. Wang Lung said to Lin Xu.

"Brother Wang Long, I just want your strength to improve faster, so I specially gave it to you, so you can accept it. Lin Xu said to Wang Lung.

"Okay, big brother, then I'd better be respectful, thank you. Wang Lung saw that Lin Xu was so persistent, but he was disrespectful, so he accepted Lin Xu's kindness.

Immediately, Wang Lung thought that the leopard print also urgently needed to increase the speed of cultivation as much as himself, so he asked Lin Xudao: "Big brother, can this magic bead leopard brother use it?" Since it can be recycled, then I want to share it with the leopard brother to speed up the cultivation speed and improve the strength together, so as to share the heavy responsibility for you." ”

"Well, the leopard pattern cultivation is the fire attribute, and this magic bead is the ice attribute, he can't use it. You'd better use it yourself. I'll find another way to help with Leopard. Lin Xu replied.

"Yes, big brother, I see. Wang Lung nodded in response.

Then, Lin Xuan picked up the No. 2 small box and carefully opened the box with the method just now.

I saw that the No. 2 locket also only had a ray of light shooting out, and it did not emit a cold aura, not even a little breath, which made Lin Xu and the brothers around him feel very calm.

There was a delicate sword in the second box, but the sword was so small, just over two inches long, that it looked more like a child's toy, and it was hard to believe that it was a treasure. But since it is placed in such a top-secret box, it will naturally have its extraordinary features.

At this moment, Lin Xuan stared at this miniature sword, his eyes were already shining, and his expression became very excited, obviously knowing its origin and function.

Wang Lung had already seen the words "Blue Ice Sword" engraved on the sword, and he couldn't help but feel extremely surprised. He thought that Lin Xu's cultivation technique was the Blue Ice Heavenly Sword Duel, which was exactly in line with this Blue Ice Sword. At the same time, he also noticed the look of surprise on Lin Xu's face, and he expected that this sword must be of great use to Lin Xu.
