Lu Guichi immediately asked: "What kind of secret is worth taking such a risk? Why is the answer to this mystery in Sishui Prison?"

Lin Wu glanced at Lu Guichi and also looked at Shi Ying.

"Don't worry. Since I want to cooperate with someone like Miss Lin, I will tell you everything. This will show my sincerity and let Lord Bai Hai feel at ease to take risks with me."

Shi Ying slowly changed his sitting position and spoke slowly.

“It all started a few months before I was put in Surabaya Prison.”

"At that time, I was still in Continent R, and I was negotiating a deal with China. But on my way to China, I met a woman. At that time, this woman was being chased by someone, and when she had nowhere to go, she actually asked me for help. I did help her."

Lin Wu raised his eyebrows slightly, "But Mr. Shi doesn't seem like such a kind person."

"Yes, I am not."

Shi Ying seemed very pleased with Lin Wu's recognition of him, and he didn't care. He said, "I helped her because I saw something interesting. At that time, she was injured and had no clothes to cover her body. There was a very beautiful phoenix tattoo on her exposed upper body. And it only appeared when she accidentally touched it with warm water."

Lin Wu's expression changed slightly.

Isn't this the woman she met three years ago? ! Then Shi Ying said, "I am very interested in her strange tattoo. It is obvious that she is not an ordinary person. And it happened that I was well-informed at that time. I heard that there was a person in the underworld who had a similar tattoo. I thought to myself, this woman could be that person."

"Are you talking about Laoshan?" Bo Ning asked in surprise.

"Hey, you young man, have you ever heard of Lao Shan's name?"

Shi Ying looked at Bo Ning in surprise, then glanced at Lin Wu. But when he thought about their relationship and Lin Wu's identity, he didn't feel so surprised.

He said, "Yes, it was Lao Shan. Lao Shan is very mysterious in the underworld, never shows his face, and acts in a low-key manner. But Lao Shan also has maritime channels that are no less powerful than Bai Haizhu, so I naturally want to save her and make friends with her. But after arriving in China, I was sure that she was definitely not Lao Shan. Because she was not only being hunted by someone, but also isolated and helpless. It is impossible for Lao Shan to be so embarrassed."

"But because of the tattoos on her body, I thought she might have some connection with Lao Shan. So I went to test her, but I discovered something incredible instead."

Looking back on that time, Shi Ying still finds it novel.

"That is - the phoenix tattoo on her body is alive!"

"Living? What kind of living do you mean?"

Lin Wu couldn't help but take a step forward.

Bo Ning next to him was also confused.

"She was alive in the literal sense. I saw her tattoo emerge with my own eyes. She then bit her fingertips and dripped blood on the phoenix's head. Then the entire tattoo moved around her body and finally settled on her heart." Shi Ying said. As expected, Feng saw Lin Wu and Bo Ning's stunned astonishment.

Shi Ying said, "I realized something was wrong right away, so I went in and asked her. She begged me not to tell anyone, so I threatened her with it and she finally told me that the tattoo was actually a map that could lead people to an underground city with amazing wealth and incredible adventures!"

Shi Ying was somewhat displeased by Lin Wu's questioning. He sat up straight and said solemnly, "That is a map! She said that the tattoo was accidentally painted with special pigments and special techniques more than ten years ago. The special thing is that, at ordinary times, it is indeed just a phoenix, but as long as the corresponding raw materials are found and applied, the map hidden in it will be revealed!"

"You believe this?!" Bo Ning asked in disbelief.

Doesn't this sound outrageous and not true at all? Shi Ying raised his voice to refute, "In order to make me believe that she was not lying to me, that woman even told me her origins! She was originally a member of the S District in Huaguojingzhong more than ten years ago, and later followed the then captain on a very secret mission, but ended up encountering danger and the whole team was destroyed."

Lin Wu's heart skipped a beat, and he was immediately sure that Shi Ying was talking about the "511" case.

So this woman is from the team of Bo Qingcheng, Bo Yuting's uncle, and was a member of the team that carried out the "511" mission back then!

Shi Ying continued, "She said that when she lost consciousness, she thought she was going to die, but when she woke up again, she found that she had that tattoo on her body. She spent a long time to determine that she survived because of that tattoo! And she was at the entrance of the underground city at that time!"

"It took her many years to figure out the meaning of the tattoos on her body, and then she tried to escape. But the people guarding the dungeon were afraid that she would reveal the secrets of the dungeon, so they kept hunting her down. I'm sure that I don't know the people who were hunting her down, and I can't find out where they came from. If they weren't the people from the dungeon she mentioned, who else could it be?!"

Lin Wu couldn't help but recall the time when he met that woman three years ago.

Yes, the woman's situation was indeed strange at the time.

But she couldn't figure out why that woman, who had such an important identity, was willing to die to save her? And why didn't she return to Area S immediately? Lu Guichi's voice suddenly rang out at this time: "Do you believe her words just because of these?"

"Of course not."

Shi Ying snorted and laughed, and said proudly: "I am so smart, how could I be fooled so easily! After she finished speaking, I asked her if she had any evidence, and she did produce evidence. In her bag, there was a Buddha head. I saw with my own eyes that after the Buddha head approached her tattoo, it suddenly emitted a green light, and many words appeared on the surface of the Buddha head!"

"I'm sure those characters are not any known characters. They are very strange. The woman even said that the Buddha head was something she risked her life to get from the people guarding the dungeon. It contains the secret of why her team members were wiped out."

Lin Wu frowned. Could this be the Buddha head she saw under Pier 9?

At that time, she only discovered the difference in the Buddha's head through the mystical arts, and there was no word on the Buddha's head. Could it be that the tattoo would only appear when one approaches it? What is the principle behind this? "At this point, after seeing such a miraculous thing, how could I not believe it?" Shi Ying's words drew Lin Wu's attention back.

Bo Ning was puzzled and asked, "Since that woman is here, she must know how to get to the underground city. Can't you just let her take you there? Why do you have to come to Surabaya Prison? What does this have to do with it?"

"What's the hurry? I haven't finished speaking yet."

Shi Ying said, "Of course I asked her to take me to find the underground city with wealth and adventures. But she said that the underground city was in a very dangerous place. Not to mention how difficult it was to get there, even if we found it successfully, she couldn't get in."

"Because the tattoo was not born with her, but was artificially added later. The tattoo can keep her alive near the dungeon, but it can't keep her from entering or leaving the dungeon. Only people who are born with the tattoo can open the dungeon."

"Therefore, even the clan guarding that dungeon cannot enter it."
