Because Qianqian already detected that there is an empty space two hundred meters below, they have to go down and open it to find out what's inside...

Ye Hao brought the rope, threw five ropes down, and then tied the other end of the ropes to a big tree.

"Be careful when you go down," Lin Ruyu advised Ye Hao from atop the rhino.

"Yeah! Don't act impulsively, think before you do anything," Xia Zhu also advised, looking at Ye Hao.

Ye Hao smiled and nodded, assuring them he wouldn't be reckless, and then he slowly descended with the four others.

Seeing Ye Hao and Lu Yunsong skillfully go down, Xia Zhu and the others curiously asked, "Ruyu, you live with Ye Hao, do you know what he used to do since he's so skilled?"

Xia Zhu's words also piqued the curiosity of Ji Keci and Chen Shuyan, and although Tan Rong had heard her brother mention something, she wasn't paying much attention at that time, and later she felt too embarrassed to ask Tan Ming, so she didn't know what Ye Hao did either!

Lin Ruyu shook her head and said, "It's not that I don't want to tell you, it's that this man is too mysterious, and it's not like we can know just because we want to! Only my dad knows his background."

Su Qing chimed in, "Yeah! We don't know where Ye came from, we only know that Ye started as our bodyguard, and then... is not really a bodyguard anymore, right? Yuyu?"

Lin Ruyu nodded and gave a slight sound of agreement.

"That's strange, a few days ago in Yanjing, he beat up two grandsons of one of the five military families, the Hou Family, and he's still doing well, isn't anyone daring to trouble him?" Chen Shuyan asked in confusion.

"Haha, maybe he has some strong backing?" Lin Ruyu chuckled, thinking if my dad were to step in, perhaps that Hou Family would have to weigh their options?

They chatted away, gossiping, while Ye Hao led Xue Zhaolong and the others down two hundred meters.

"Master, inside is the empty space," Qianqian's voice came through.

Ye Hao looked at the wall and found it completely unmarked, he was stunned, was this really the entrance to the secret chamber?

"Qianqian, are you sure it's inside?" Ye Hao asked.

"Yes, Master, inside is the empty space," Qianqian confirmed.

"But why is there no mark at all? If this is the entrance to the secret chamber, how did the owner get in?" Ye Hao was even more puzzled.

However, thinking that they still didn't have a foothold, Ye Hao instructed Lu Yunsong and Xue Zhaolong, "Long! You go to the left and tie a rope to pull over, Song, you go to the right, we'll use the ropes to support our body later."

The two nodded, then went to pull the ropes apart, while Tan Ming and Zhuorong Town helped tie the ropes together.

With the aid of these ropes, they stood steadily in the void, although it swayed a bit, for people like them with National Martial Arts skills, such swaying wasn't a big issue.

"Boss! Is the door here?" Xue Zhaolong asked after coming back.

"Yes! But I also can't figure out why there's not even a gap here," Ye Hao said with a helpless smile.

"Then let's check it carefully!" Zhuorong Town suggested.

So they checked inch by inch, and at this moment, Qianqian exclaimed, "Master, feel this wall, see if it's incredibly hard?"

Ye Hao thought, isn't that obvious? But he still said to Qianqian, "Right, it's extremely hard."

Upon hearing Ye Hao's affirmative answer, Qianqian excitedly said, "Master, don't rush to find it, if the system's check is correct, this isn't ordinary material."

"What do you mean?" Ye Hao asked in confusion.

"Based on the information from the eighth-generation system, I did a calculation; this material isn't ordinary, if correct, it's the adhesive mineral used in aerospace vehicles, this material is fire-resistant, weather-resistant, and the only way to dissolve it is to use the body's Inner Breath."

"What? You say it's adhesive material? Are you kidding? I just happened to find it on a casual treasure hunt?" Ye Hao was stunned, as the submarine needed such material recently, and now he found it?

"Master, you can perform a test, try using your Inner Breath to dissolve this mineral, if it can be dissolved, then it's adhesive mineral, if not, it means it's beyond what the eighth-generation system can know."

"Alright!"

Ye Hao released his Inner Breath, then directed it towards the wall.

At first, the wall showed no reaction, but after about a minute of Ye Hao releasing his Inner Breath, the entire wall began to soften.

Ye Hao pressed it with his hand, and the hard stone block became soft.

Seeing this, Ye Hao rejoiced, and told Xue Zhaolong and the others, "Quickly release your Inner Breath, and direct it at the wall."

Ye Hao's words surprised them.

"Boss, why are we doing this? Have too much Inner Breath to release?" Lu Yunsong asked, puzzled.

"Trust me, just do it quickly," Ye Hao stopped their conversation, urging them to help quickly.

To avoid the previously softened part from hardening again over time.

Ye Hao released Inner Breath while pulling the softned material towards him.

The once steep wall now had enough space for a few people to stand on the adhesive material.

Seeing this, Ye Hao laughed, "Do you know what these are?"

"No idea!" They gritted their teeth, showing they were exhausted from using so much Inner Breath.

"Our submarine needed an adhesive material before, right? This is the adhesive material we've been looking for, if we use this material on the submarine, it will prevent any water ingress and there's no need to worry about speed issues," Ye Hao explained with a smile.

"Wow! How can it be so coincidental?" Lu Yunsong exclaimed.

"Haha, isn't a little coincidence good? At least this trip wasn't in vain," Xue Zhaolong laughed heartily.

"Hehe, I think the real surprise is inside, isn't it?" Tan Ming was unusually excited, surprised to find a mineral so easily on this trip.

"Put in some effort! If you want to see what's inside, do it faster," Ye Hao encouraged them.

So everyone continued to exert their Inner Breath, and after about an hour, the five finally entered the cave.

Ye Hao was holding a mineral ball combined by four or five people's worth of material, and after storing it in his space, he entered the vast cave.

The cave was dim and dull but extremely spacious, at least the size of a sports field!

"Boss! There are so many bookshelves here, could there be some great martial arts manuals?" Xue Zhaolong asked, looking at the bookshelves filled to the left.

"I don't know, we'll know when we start looking," Ye Hao replied with a smile, though his eyes were fixed on the skeleton in the center. (To be continued.
