After Lin Xuan put away the Overlord Dan, he suddenly thought of an important matter. That's secrecy. Because the Overlord Pill is a treasure that many swordsmen, especially those who have cultivated to the realm of Sword Overlord, dream of. Without it, the Sword Overlord Monk may not be able to upgrade to the Sword King realm, but with it, he will definitely be able to succeed. This shows how attractive the Overlord Pill is to cultivators.

Now Lin Xuan is still just a swordsman with the strength of a sword soul, if other swordsmen who have reached the sword overlord realm know that he has the Overlord Pill on him, then in order to ensure that they can upgrade to the Sword King realm one hundred percent, they will definitely try their best to snatch the Overlord Pill. At that time, Lin Xuan will inevitably fall into danger. No matter who it is, as long as the thought of being targeted and even hunted down by a swordsman whose strength far exceeds his own, it is a chilling bad thing.

Although Lin Xuan is not timid and afraid of death, no one likes trouble, and it is better to avoid the trouble and danger that will arise even if he knows it. This requires all the people present, including Wang Long and the soldiers, to help Lin Xuan keep it secret, and absolutely not to spread the news that he has obtained the Overlord Pill.

So, Lin Xu immediately told Wang Long: "The Overlord Pill is very precious, there are too many people who think of it, I don't want others to know that it is on me, except for our own trusted brothers, this matter must not be revealed to outsiders." ”

The trustworthy brother that Lin Xu said obviously meant Leopard Print and others, and Wang Lung was naturally able to comprehend Lin Xu's meaning. He immediately nodded in agreement with Lin Xu: "Yes, big brother, I understand." ”

Immediately, Wang Lung turned around and said loudly to all the soldiers present: "Brothers, the matter of this cave is very important, everyone must pay attention to secrecy, and do not cause trouble to the eldest brother." ”

"Yes!" the soldiers listened and nodded their heads with serious expressions. They were all high-ranking soldiers selected by Wang Lung after careful selection, and they were stronger than ordinary people in terms of force and intelligence. They were fully able to understand the profound meaning of Lin Xu's and Wang Long's words, and they also knew the importance of this matter, so they promised that they would never spread it casually.

Lin Xuan completely trusted his soldiers, believing that they would do what they said, and would never deceive and betray themselves. He didn't need to worry about this anymore, and continued to open the remaining small porcelain vase, which was also the last one.

Lin Xu already had the experience of opening the big porcelain vase, and now he did the same, and quickly opened the small porcelain vase in the same way. There was no bright light coming out of the bottle, just a strong smell of herbs.

"Could it be that there are some herbs in here?" Lin was secretly suspicious in his heart.

When he looked closer into the bottle, he realized that it was not filled with herbs, but some white powder. This made him feel even more surprised and confused. Because he had never seen this powder before, and he didn't know what it was called.

Wang Lung was the closest to Lin Xu. When the bottle was opened, he smelled the smell of herbs emanating from the bottle almost at the same time as Lin Xu. Now when he saw the powder in the bottle clearly, he guessed and asked Lin Xudao, "Big brother, is this the medicinal powder for treating injuries?"

"At first, I thought it was a medicinal powder, but now that I think about it, it seems that the medicinal powder is not white yet, and we have never seen a white medicinal powder. I don't think it's a medicinal powder. Lin Xu's suspicious tone went back and forth to Wang Lung. He wasn't sure either.

"Oh, yes, the powder won't be white. So what is this?" Wang Lung then asked Lin Xudao.

"I don't know either. Lin Xuan shook his head, put the bottle in front of him again to carefully discern it, and sniffed it with his nose, but he still couldn't determine what the powder in the bottle was.

"Big brother, this can't be poison, right?" Wang Lung thought about the worst, and it could be regarded as a kind reminder to Lin Xu. He didn't want Lin to fall on top of such a small bottle of powder.

"No, it can't be poison. If it was poison, it wouldn't be in the same big iron box as the Blue Ice Sword and the Overlord Pill. There was no need for the predecessors to bother to hide it in this secret cave. And one more thing, its smell is particularly pure, after smelling it, people can produce a particularly comfortable feeling, and there is no discomfort. This is definitely not a smell that poison can have. Lin Xuan shook his head and replied to Wang Longdao. He was sure of this, and he believed that he would not be wrong.

"As long as it's not poison. Then you can take it with you first, and then find a way to figure out what it is when you have the chance. Wang Lung finally put his mind at ease, and also took the initiative to give Lin Xuan a suggestion.

"Well, that's all there is to it. I'll take it to the master when I have time, and she'll be able to recognize what the powder is. Lin Xuan nodded and said.

Lin Xu's master Bai Qing is well-informed and unfathomable. Ever since Lin Xu knew her and worshipped her as a master, he felt that there was nothing she didn't know, and there was nothing she didn't know. Lin Xu believed that as long as she took the powder in the bottle and showed it to Bai Qing, she would tell her the name of the powder.

"Boom—"

As soon as Lin Xu put the small porcelain bottle containing the powder into the ring, a sound like thunder suddenly sounded in the cave. But of course, there will be no thunder here, and Lin Xuan suddenly felt a little bad.

Wang Lung and the soldiers also heard this loud noise, their courage and determination were not as great as Lin Xu's, and they couldn't help but be startled by this sound.

Lin Xu and the soldiers looked up at the same time in the direction from which the sound came, and saw that the place where the iron box was placed just now on the top of the cave had already shaken violently, as if the stones on the top of the cave and even the entire cave were about to collapse due to the absence of the magical iron box.

Lin Xuan reacted first, and hurriedly shouted: "This cave is about to collapse, brothers, run!"

Lin Xuan said, already pushing some soldiers who were stunned by this sudden danger to retreat in the direction of the cave entrance. After Lin Xu's verbal reminder and the push with his hands, the soldiers reacted, so they didn't dare to hesitate for half a minute, and hurriedly ran towards the outside of the cave entrance.

Wang Lung saw that Lin Xuan was only concerned about telling the soldiers to retreat, but he was still standing on the spot and looking up at the changes in the stones on the roof of the cave, as if he wanted to keep a close eye on when the stones on the roof of the cave fell, so as to react in time and prevent the stones falling from the sky from falling on the soldiers.

"Big brother, you run too. It's too dangerous here. Wang Lung shouted loudly as he grabbed Lin Xu's arm and prepared to run out with Lin Xu. He knew that Lin Xuan was concerned about the safety of the soldiers, but he completely forgot about it, so he needed to pull him along.

Unexpectedly, Lin Xuan quickly broke free of Wang Lung's hand and said loudly: "Wang Lung, you and brothers run together, I will break the queen for you." ”

Lin Xu said, he had already drawn his sword, ready to make a move at any time. Although there are no other enemies in the cave now, stones falling from the roof and around the cave can still smash and injure the soldiers. The enemy who has been deprived of these stones, he must smash the stones that may fall on him and his soldiers in order to ensure the safety of himself and his soldiers.

After all the soldiers ran outside the cave, Lin Xu followed behind the soldiers and was the last to retreat. At this time, I saw that the stones on the top of the cave had fallen one after another, and they hit the ground with a loud "dong dong" sound, coupled with the echo in the cave, it sounded very frightening.

Some of the timid soldiers looked back at the stones that had fallen from the roof of the cave like a heavy rain, and they were so frightened that they almost cried. They were secretly glad that Lin Xu's reminder was timely and they were able to run away, otherwise they would definitely be smashed into flesh by those stones.

However, as long as the soldiers did not completely run out of the cave, the danger was not completely removed. As the rocks on the roof of the cave fell more and more, the whole cave shook together, as if a strong earthquake had occurred.

As a result, not only the stones on the roof of the caves will fall, but even the stone walls of the caves will produce huge cracks, forming stones of equal size to roll down.

The situation is really critical. As long as a stone hits a soldier, it will surely kill a soldier. Lin Xu didn't want any soldier to die here. The lives of soldiers are precious, and their lives should belong to the battlefield to preserve the dignity and integrity of the empire, not to an accident that occurred in this cave.

"Blue Ice Nine Flashes!"

Lin Xuan shouted, and waved the sword in his hand vigorously, only to see a blue light with strong power shoot towards the falling stones, smashing all the stones to pieces.

"Bang bang bang-"

The loud sound kept ringing, whether it was from the top of the cave or falling from the cave wall, all the stones were shattered by Lin Xu's powerful sword qi, turning into bursts of powder, floating down gently, and no longer able to hurt any soldiers.

After Wang Lung and the soldiers had all withdrawn from the cave and returned to the guest room connected to the entrance of the cave, Lin Xuan was the last to retreat. He used his great strength to protect every soldier present, so that none of the soldiers were injured by sudden stones.

Lin Xu had just exited the entrance of the cave, only to see that the entire cave had been shaking even more violently. In a short time, it all collapsed, and the original cave was completely gone, completely filled with rubble.

Seeing this scene, Lin Xu and the soldiers were all apprehensive, and secretly congratulated themselves on their lives. It's a big difference between one step earlier and one step later. Now they would have survived if they had been one step earlier, and they would have died in a cave if they had been one step later.

"It's so dangerous!" Wang Lung couldn't help but sigh and said to Lin Xu: "Big brother, you have once again saved my life and the lives of my brothers, you are really our life-saving benefactor and super lucky star." With you, we can turn danger into disaster every time. ”
