Li Mu's metal sense circled around the painting's mounting a few times, and soon found an extra red copper button, which he controlled to press.

Bite!

Next to the painting, the original pure white wall tiles suddenly slid open to both sides, revealing a blue gate, and on one side of the gate, a control screen similar to an elevator was placed, on which there was only one up, one down, and a padded keyboard for entering passwords.

"It looks like I'm going to have to enter a password. Tang Yulan leaned over and stared at the keyboard intently, an ice-blue light appeared in her eyes.

However, Li Mu stood behind her, but he didn't notice this, he thought, since Li Yetong's breath disappeared here, and he didn't look back, and there were no traces of a fight at the scene, he ruled out the possibility that she was knocked unconscious and brought down, that is to say, Li Yetong took the initiative to go down.

So how did she know the password?

This reminded Li Mu of the report that had turned to page eight, and muttered:

"Could it be that there is a code word in that report, or is the password in a place we haven't looked for?"

Just as he was thinking this, Tang Yulan's body in front of him suddenly softened and fell to the ground, Li Mu's eyes were quick, and he hurriedly hugged her forward and held her up, and then saw her pale cheeks:

"What's wrong with you? Are you alright?"

Tang Yulan pinched Li Mu's hand around her waist and laughed lightly:

"There was something just now, but now it's fine, I said, I didn't eat breakfast, I'm too hungry. You help me up first, it's important to find someone. The password is 9836724181, you believe me or not, believe me and enter it to see. ”

People who haven't eaten breakfast and are hungry, Li Mu has seen it, but he has never seen such a demobilized performance as Tang Yulan, although the doubts in his heart are very strong, he still followed Tang Yulan's action of wanting to stand up and helped her up.

After Tang Yulan got up, she stood steadily, as if she was careless when she fell just now, and smiled at Li Mu, but she didn't know that her face was slightly sick in Li Mu's opinion.

What a stubborn girl, Li Mu thought to himself, and then he let go of the hand holding Tang Yulan, looked at the keyboard, and asked suspiciously:

"How do you know the password?"

Tang Yulan pursed her lips, as if she was a little disappointed that Li Mu didn't press the password directly, and then didn't hide it:

"Thanks to your little sister, she controls the fire elemental very powerfully, the most powerful I've ever seen. Have you ever heard of the Sharp-eyed Eye, and some of her abilities are similar, she can see the depth of the fingerprints left on the keyboard, so she can know the password. And I, who just happened to be more sensitive to the fire element, saw her input trajectory, not so much to make you believe me, but to make you believe her. ”

Li Mu touched his nose and felt a hint of resentment in Tang Yulan's tone.

If it was Li Yetong, her control of her own ability was indeed the strongest Li Mu had ever seen, and Li Mu also woke up, Tang Yulan's sensitivity to the fire element was not just the degree of "comparison", when he came here, Li Mu first went to the window to find clues, because he knew that the window was the most likely place to leave traces, and Tang Yulan went directly to the workbench, because she knew that Li Yetong had been there and stayed for a long time, so the remaining fire element was so rich.

So, Li Mu walked to the elevator and entered the password without hesitation.

Another ding.

The elevator started and began to make a slight rumbling sound, as if the elevator was gradually rising from a deep ground.

Waited for about 10 seconds.

The blue gates open to both sides, revealing the neat car inside.

Li Mu glanced at Tang Yulan and wanted to say, "Why don't you wait for me here, or do you go back first?", but seeing Tang Yulan's excited expression, the words came to his lips and became:

"You follow me, tell me if you feel unwell. ”

Tang Yulan hurriedly nodded, indicating that she was absolutely obedient.

However, Li Mu didn't believe it, and could only hope that she wouldn't force herself.

After stepping into the elevator, Li Mu hesitated for a moment and asked:

"Go up or go down?"

Tang Yulan knew that Li Mu was asking her where the fire element was strong, so she said directly:

"Down. ”

Li Mu did not hesitate this time.

As the elevator descended, the surrounding sounds became quieter and quieter, as if isolated from the world, and it was impossible to guess how deep the elevator would be to the ground, and no one dared to think about why a small middle school had such a big privilege and did such a big construction.

I don't know how long it took, Li Mu finally felt the signs of the elevator stopping.

Bite!

The floodgates are wide open.

Li Mu and Tang Yulan glanced at each other and walked out first.

The next second.

Li Mu was stunned, where he saw it, was a crystal mine that emitted a crystal blue light, irregular shape, scattered all over the ground, distributed everywhere, if he thought right, this should be the rumored super crystal mine, and it was born here.

"No wonder this laboratory must be built here, the super energy crystals here can't be used up at all, whether it is extracting crystal energy or testing the effectiveness of the polymer dish, it is excellent. Tang Yulan's expression seemed to have seen a super continent, and obviously she had never seen so many unprocessed super energy crystals.

"Your face is better. Li Mu nodded, agreed, and then said casually.

Tang Yulan said um, glanced around excitedly, didn't notice Li Mu's concern for her, and explained:

"They're replenishing my super energy. ”

Super energy?

The first time Li Mu saw this new word, just as he was about to ask, there was a slight echo between the mines, as if something had fallen heavily on the ore.

"Keep up!"

Li Mu walked quickly along the vacated path between the ores and walked inside, and Tang Yulan was also walking like flying, she had a feeling that here, she no longer had to worry about her body, here, she could consume her super energy wantonly, and she didn't have to worry about the follow-up.

This is very strange, and the family has prepared a lot of processed super energy crystals for her as a healing function, but it didn't make her feel like this.

Can't it be processed?

Tang Yulan's heart was confused and thinking, and at the same time, his body technique was not hindered by his single-mindedness, so he quickly dodged the hard crystals scattered on the ground and followed closely behind Li Mu. Looking at his back, Tang Yulan smiled sweetly, every time she met him, there would be good things.

It had been like this since many years ago, and although he didn't seem to take it to heart, she would never forget it.

The road in the crystal mine cave was definitely not like this at first, but it was walked more by people and more ore was dug up, so there were some walkways similar to roads.

Li Mu was very cautious, controlling the knife that had cut off the monitoring power before, flying ten meters away from Li Mu, taking the lead, and Li Mu followed closely. As the distance decreased, the vibrations coming from inside the mine became more frequent.

There are people fighting, and there are quite a few of them.

After a while, Li Mu withdrew his knife and motioned for Tang Yulan to slow down, because the maker of the sound was already close at hand, and he could see it by bypassing a corner in front of him.

Tang Yulan said she understood, and said in a low voice:

"That friend of yours should be in there, I can feel it, a very strong and violent fire element, she should be very angry. ”

As soon as the words fell.

Boom!

A man dressed in black, carrying a wisp of crimson flame on his chest, flew out of that corner and slammed into the crystal-made wall, which had nothing to do but his eyes were white.

Li Mu's figure who wanted to rush forward paused for a moment, as if thinking of something, glanced at Tang Yulan, and admonished:

"Let's be careful later, this little girl is angry, and everyone will beat her. ”

Tang Yulan's expression was strange:

"She hit you?"

Li Mu shook his head:

"Not yet. ”

Tang Yulan frowned, her eyes narrowed, and she was silent.
