After a burst of sparks, a small crack appeared on the metal door. This small crack at least gave Li Xiaoyao hope.
Li Xiaoyao repeated his old trick, still lightly scratching the original place, so the crack became deeper. After ten consecutive times, the crack had penetrated about one centimeter into the metal door.
The scratches caused by the first cut are the least obvious, but the scratches made by each cut along the same place are more obvious.
"It seems that the texture of this metal door is not exactly the same. The so-called unbreakability is mainly due to the addition of harder materials to the surface of this metal door."
Li Xiaoyao thought to himself, when he swung the dagger again, the force had been increased several times, and he only heard a hissing sound as he remembered that the effect of this knife was comparable to the previous eleven knives.
"The family heirloom is indeed worthy of its reputation. It has already produced such an effect before I even use my powers. If I use my powers, it's not impossible to break in."
The dagger in Li Xiaoyao's hand suddenly shone with golden light. After adding super powers, the sharpness of the dagger underwent a completely new qualitative change.

Li Xiaoyao's casual knife actually penetrated the metal door half an inch deep. In this way, as long as he continued to stab the metal door with the dagger, he could break in soon.
Since he didn't know the thickness of the metal door, Li Xiaoyao started from the middle of the metal door, first drew a personal-sized mark, and then followed the mark gradually deeper into the metal door.
After that, Li Xiaoyao divided the metal door into several parts, so that the efficiency of breaking in would be greatly improved.
When using all powers to wield the heirloom dagger, almost every cut can penetrate about an inch.
Half an hour later, Li Xiaoyao had dug a deep square pit along the scratches. In this way, as long as the outermost layer of the metal door was opened, a new door would be opened on the door.
You can enter through this new door.
"Xie Zheng, if you make a bet with me, you will definitely lose."
Li Xiaoyao secretly laughed in his heart, and then he began to dig out the metal blocks on the door with great energy. Using the sharp dagger passed down from his family, after another half an hour, the upper door was pierced by the dagger.
This door is nearly one meter thick. If it weren't for the sharp dagger in Li Xiaoyao's hand, it would be impossible to break in.
It took Li Xiaoyao another two hours to puncture most of the metal door, leaving only a few connection points.
After doing this, Li Xiaoyao practiced cross-legged and restored the powers in his body to their peak state before walking out of the cave.
Outside the cave, Xie Zheng was already lying on the grass and fell asleep, with a happy smile on his face. As soon as Li Xiaoyao came out of the cave, Xie Zheng opened his eyes.
"Hey, how about it! Are you ready to accept me as the boss?"
Xie Zheng said confidently.
"The door is about to open, we are ready to go in and rescue people!"
When Li Xiaoyao said these words, Xie Zheng was so frightened that he jumped up from the hillside and almost rolled down the cliff.
"No! If you want to fool me, you won't do this! Okay, I'll go in and take a look. I don't believe you opened the door so quickly."
Xie Zheng said in surprise, and a man rushed into the cave first.
"Haha, the door is still there! Now you are going to be my little brother!"
Xie Zhenggang laughed out loud, but then stopped laughing, because the light came through the door, which meant that the surrounding sides of the door had been pierced.
"Come here and help! Lift this metal door out and let's sneak in quietly."
Li Xiaoyao lowered his voice and said, Xie Zheng was speechless and cooperated with Li Xiaoyao to lift the one-meter-thick metal door.
But with a flash of golden light, the metal door was completely separated from the door. Even Xie Zheng didn't see clearly what the golden light was all about.
"This is impossible. How could he dig through such a strong door? Do the Vampires also have fake doors?"
Xie Zheng struggled to lift the one-meter-thick metal door. The metal door he dug weighed at least 10,000 kilograms. If the two had not had powerful powers, it would have been impossible to lift the door.
When the entrance to the cave was revealed, Li Xiaoyao had already entered the secret place in a flash.
Xie Zheng was speechless and followed him in without hesitation. He felt that Li Xiaoyao had created a miracle. He was afraid that the vampire clan would never dare to say that this metal door could defend against all short-term attacks.
After the two entered the cave, there was no one inside. It seemed that the vampire wanted to conceal the location of the metal door.
"Li Xiaoyao, are you plotting against me on purpose? Damn, you can open this door. You are more powerful than God."
Xie Zheng said speechlessly.
"You should change your mind now and call me boss!"
Li Xiaoyao chuckled, looking at Xie Zheng's unconvinced look, he couldn't help but feel happy.
Xie Zheng was not willing to call this guy who was much younger than himself boss, but willing to admit defeat, Xie Zheng had no choice but to call him boss in a depressed manner.
"Be good, I will buy you some candies from now on, haha!"
Li Xiaoyao said funny, Xie Zheng could only apologize in embarrassment, and couldn't help but regret the bet he made just now, and had vowed never to bet with Li Xiaoyao again in the future.
"This seems to be a secret room with walls on all sides. It must be a metal door that the vampires want to hide here!"
Li Xiaoyao put away his smile and said seriously.
Xie Zheng nodded, then observed the surrounding walls, and then put his ear against the wall, hoping to hear the movement inside.
"Ah! This wall is made of the same material as the metal door. I'm afraid you have to cut a hole in the wall again."
Xie Zheng knocked on the wall and said with a helpless smile.
"No way! You want me to be a digger again! You don't know how tiring it is to dig a door! Doesn't this vampire hate the trouble? What on earth do you want to do with such an awesome fortification!"
Li Xiaoyao looked around speechlessly, and found that the walls on all four sides were exactly the same as the metal door, and he couldn't help but feel a little angry.
