Back at Duanmu Jieyu's villa, Qin Yan sent the secretly taken photo of Billy to Xue Bing, asking her to help investigate Billy's identity. Knowing oneself and knowing one's opponent can win all battles, not to mention, the situation we are facing today is very complicated, the clearer you understand the other party, the more you can protect Duanmu Jieyu.

Now it is not only Billy who is facing it, but also the mafia members from Russia, who are also coveting the equation in Duanmu Jieyu's hand. It's just that I don't know what methods they will use and who they will find to help. Duanmu Jieyu's situation can be described as a crisis step by step, with risks everywhere, however, she is still like no one, and after returning home, she exercises, bathes, reads, and is leisurely. This calmness and calmness made Qin Yan admire.

"Where did you go with my grandfather tonight?" Duanmu Jieyu, who had taken a bath, walked into Qin Yan's room wearing simple home clothes. Although it is very simple, it still can't hide her beauty at all. Rao is Qin Yan has seen so many beauties, and he still has a feeling of brightness when he sees her.

"If you want to know, you can ask your grandfather. Qin Yan said lightly.

"When I asked him, he wouldn't say. Duanmu Jieyu said.

"Your grandfather doesn't want to say it, that is, he doesn't want you to know, and I can't say it. Qin Yan said.

Stunned, Duanmu Jieyu glanced at him, suppressed the anger in her heart, and said, "You don't say that I also know, grandpa is for my business, right?

Qin Yan was stunned for a moment, he didn't expect this girl to be quite smart. He shrugged his shoulders and said, "Since you know everything, why bother asking me?"

"The person who kidnapped me that night was the one who went down the mountain, and I had heard the name of the downhill tiger, and he was also famous on Longcheng Road, specializing in training knife hands. However, with the forces of the following mountain tigers, he would never dare to take the risk of offending our Duanmu family to kidnap me. Therefore, I am sure that there must be someone behind the Xiashan Tiger, and besides, this person's power can even be so strong that the Xiashan Tiger does not have to fear the retaliation of my Duanmu family at all. Who is this person?" asked Duanmu Jieyu.

Qin Yan originally thought that Duanmu Minghao was deeply hidden, and he saw many things in his eyes and knew it in his heart. I didn't expect Duanmu Jieyu to be able to see it so thoroughly, as if she knew everything.

Taking a deep breath, Qin Yan said, "That person's name is Billy, and he is a foreigner, and we don't know what his identity is. However, judging by his attitude and tone, the origin should be not small. Tonight he's made it clear that if your grandfather doesn't want to hand over the equation, he's going to do it to you. Now that the matter is on the table, we don't know how many of them there are and what they will do. For your safety, I think it's best for you to stay at home and go out less during this time. ”

"What should come is always coming, and dodging is not the way. Even if I hid at home, this matter would not have been resolved. All they want is an equation, and even if they kill me, they won't be able to succeed. Duanmu Jieyu said firmly.

"Some things are not as simple as you think. Since they dare to come to China for the sake of the equation and take such a big risk, they are absolutely capable of forcing the equation out of your mouth. However, I admire you for being so calm and calm. Don't worry, I've got someone looking for information about that Billy. I will also do my best to protect you during this time, and as long as you are in my sight, I can make sure that you are safe and sound. Qin Yan said.

When the words fell, Qin Yan's brows suddenly frowned, and he jumped up from the chair.

"Stay in the room, I didn't call you, you are not allowed to come out. Qin Yan's tone was unquestionable.

Duanmu Jieyu also realized the danger and nodded heavily.

Qin Yan went out and closed the door. picked up the fruit knife on the coffee table in the living room, and suddenly threw it out. Accurately through the window and into a person's throat. In an instant, the gate was kicked open, and more than 20 people swarmed in. Qin Yan's gaze swept over them one by one, his brows furrowed slightly, and he was surprised in his heart, the murderous aura he had noticed just now was not emanating from these people. It seems that the real master has not yet appeared.

"Do it!" A man led by him waved his hand, and there were no extra words, and suddenly, a group of people rushed towards Qin Yan. Everyone was holding *, and they made a move to take their lives, obviously intending to take Qin Yan's life.

These people are all knife fighters trained by the Lower Mountain Tiger, and all of them can be regarded as having special skills. It's really hard for three or four people to get close to them. It's a pity that they are not facing others, but Qin Yan.

Qin Yan didn't expect Billy's actions to be so fast, as soon as the negotiations ended, he immediately asked the people of the Xiashan Tiger to do it, and it seemed that he couldn't wait to get the equation in Duanmu Jieyu's hands. It is not surprising that it is not only him who is eyeing this equation, but also the mafia from Russia. Whoever grabs it first can dominate the entire drug market in Europe, the United States, and even Asia. The huge profit in this is enough for them to do whatever it takes.

A cold light flashed, and spirit wings appeared in his hand. Qin Yan shuttled through the crowd, like a tiger descending a mountain, unstoppable.

Qin Yan didn't show the slightest mercy when he made a move, this was a battle of life and death where either you died or I died, and there was no room for negligence.

There were bursts of screams, Duanmu Jieyu, who was sitting in the room, frowned, from the loud noise, she could hear that there were a lot of people coming this time, and she couldn't help but worry about Qin Yan's safety. Taking a deep breath, Duanmu Jieyu got up and opened the door, and saw Qin Yan constantly shuttling through the crowd like a swimming dragon, the cold light flashed, and one person must have fallen to the ground and died.

She, after all, was just an ordinary person, and she had never even seen a dead person, let alone such a situation, and she was stunned on the spot.

"Catch her!" Seeing Duanmu Jieyu, the man led shouted.

Suddenly, someone rushed towards Duanmu Jieyu. Their target was Duanmu Jieyu, as long as he was captured, Qin Yan's life or death did not matter to them.

Qin Yan was stunned for a moment, turned around and kicked one of them fiercely, and the spirit wing in his hand emitted a cold cold light, cutting through the throat of one person.

"Who let you out, go in!" Qin Yan shouted.

"I'm not worried about you. Duanmu Jieyu said with some grievances.

"Go in!" Qin Yan shouted sharply, his tone unquestionable.

Duanmu Jieyu bit her lip, dropped a "be careful", and turned around and entered the house.
