However, Li Sibai seems to have made up his mind quickly, he has no way to retreat now, his arms are frozen in ice, not to mention, if he can't find a way out here, then he can only go back from here, or face the owl, and after he played it just now, it is almost impossible to retreat from him again.

Thinking of this, Li Sibai no longer hesitated, and as soon as he picked up the Xuantian Sword in his hand, the lid of a wooden box was opened, without any prohibitions and mechanisms, and it was absolutely safe. But to Li Sibai's disappointment, the box was empty, and there was nothing left.

Li Sibai was a little disappointed in his heart, and then successively picked off the lids of these boxes, but when the empty boxes were placed in front of him, he felt a little incomprehensible.

But soon Li Sibai recovered from his disappointment, this underground palace has existed for I don't know how many years, and it is estimated that he is not the only one who can break into here, and it is not so strange that the treasures here have been swept away now. Thinking that he came here by chance, and he didn't come specifically for these treasures, Li Sibai was relieved.

With a wry smile and shaking his head, Li Sibai walked down the stairs to the second floor. The second floor is smaller than the first floor, with only a bed and two bedside tables. There were two ordinary-looking ornaments on the bedside table, and Li Sibai felt strange that unlike the previous library, the whole bed did not seem to have any dust, as if someone often came to clean it.

Li Sibai's divine sense swept the room and found that there was nothing special, although there was disappointment in his heart, but after experiencing those things on the first floor, he was able to accept it.

However, Li Sibai's eyes were finally locked on the two ornaments on the bedside table. As soon as he stretched out his hand and grabbed the void, they flew to Li Sibai's hand in unison. These two ornaments are very exquisite, one of them has a "device" word written on it, and the other has a "array" word written on it, although the two words look very good, but there is no fluctuation of spiritual power, and it is not a magic weapon at first glance.

Holding them in his hands, Li Sibai felt that they were nothing special except that they were a little heavier than expected. Li Sibai shook his head, although he was unwilling, he still had to admit that everything that was worth a little money here was probably swept away. It's just that the two ornaments in my hand, if they weren't plain themselves, probably wouldn't be here anymore.

Li Sibai hesitated, but still brought them with him, he thought that it would not be easy to come here, and it would be considered a souvenir to be able to take something back.

After staying in the upstairs bedroom for a while, after finding that there was indeed nothing, not even an entrance, Li Sibai returned to the room on the first floor.

Divine sense communicated with Mu Mingdao, Li Sibai said helplessly: "Senior Mu, please help me take a look, what is frozen on my arm?" He originally wanted to find some clues in this house, but now not only did he have no clues, but after many explorations of the exit out, he was also the one who came in just now, which made Li Sibai a little helpless, so he had to ask Mu Mingdao again to see if he had a better way. After all, he is well-informed, and there may be a glimmer of clues.

Mu Mingdao heard Li Sibai's summons, and replied a little impatiently: "Li boy, you also look for me for the big fart matter, can't you solve it yourself?"

Li Sibai smiled awkwardly and said: "Senior Mu Jianghu is in emergency, hurry up and help me take a look, otherwise I am afraid that I will not be able to keep my arm, and when the time comes, my strength will decline, how can I help you find a suitable one to go to the body." ”

After hearing this, Mu Mingdao said, "Phew!" and said: "Don't mention it, you kid, I can't remember it if you don't mention it, and I'll be angry when you mention it, how long has it been." Mu Ming Daoren continued: "Look at the ice on your arm, is there a faint blue in it?" After listening to Mu Mingdao's words, Li Sibai went to observe the ice on his left arm, but he didn't find anything.

I heard Mu Ming Daoist say, "You turn around and try it." ”

Li Sibai turned an angle slightly according to the method that Mu Mingdao said, and sure enough, he found that there was an imperceptible blue floating by, this blue was not deep, and it could only be seen at certain angles, and it would not be noticed in other circumstances.

"Could it be that this is blue ice?" Li Sibai said with some surprise, "No, this is not blue ice! If it is blue ice, my arm is probably long gone." Although Li Sibai has never heard of Qing Bing, he knows about Blue Bing.

"Yes, you know Blue Ice. Mu Ming Daoren smiled and said, "Then tell me why this is not blue ice." Mu Mingdao seemed to be interested, and he actually began to take the test Li Sibai.

Li Sibai nodded and said: "The reason why blue ice is called blue ice is because of his touch of blue, according to legend, he is a kind of ice that can reach the absolute freezing point approximation, this kind of ice is produced in the distant northern mountain range, where there is a deep blue lake, and in the deepest part of the lake, you can find a little bit of blue ice." And if this blue ice can be refined and used against the enemy, it is often only a little bit, and if it is frozen, the meridians in the entire human body will be affected, so it is very terrifying. ”

Li Sibai paused here and looked at Mu Mingdaoren, who nodded and motioned for him to continue.

"And I've been frozen for a long time now, and although it has affected the perception of my arm, it hasn't expanded yet, so I don't think it's blue ice. After Li Sibai finished speaking, he looked at Mu Mingdaoren, although he was full of confidence in his judgment, he still wanted to hear what Mu Mingdaoren had to say.

Mu Mingdaoren nodded, and said: "Yes, Li boy, it seems that I usually work hard, just like I told you just now, this is called green ice, and this is called green ice, although this is not blue ice, but it is not much worse than blue ice." ”

Li Sibai's face changed slightly after hearing this, he knew the power of blue ice, even if this green ice was not as powerful as blue ice, but if it could be compared, it would be enough to see its power. Thinking of this, Li Sibai hurriedly asked, "Senior Mu, I don't know if there is any way to crack it?"

Li Sibai heard Mu Mingdaoren say it so clearly just now, and his heart was a little relieved, thinking that he should have a way to crack it. Although these allusions are good, he is most concerned about how to solve these problems.
