After Ye Linghan got on the boat, he didn't look blindly, but found a hidden high place and secretly stared at the people on the boat.

The three of them came out of the cabin, and Ye Linghan quietly touched it.

After a few moments, there was a regular tapping sound by the window.

It wasn't loud, and it was hard to hear except for people close to the window.

Lin Yu's eyes lit up when he heard the sound, and his curved fingers tapped on the window, which was the same as the sound he had just heard.

There was a response outside, and after a moment of silence, Lin Yu heard a familiar voice coming.

"Ann?"

Lin Yu was stunned, originally she thought that Li Lei chased after her, after all, this kind of contact code was given to Li Lei by her, and asked her to teach all the coachmen of the Lin family to facilitate the handover of important goods in the future.

At the beginning, Xu Tao reminded her to want a code word for contact, after all, tokens, letters and the like are easy to obtain, but the code language is only understood by her own family.

This is also a common method for ordinary big businesses, but the code words are changed frequently, and Lin Yu is troublesome, so he remembered a movie that the school organization had watched in his previous life, which mentioned how the undercover agent wittily used the Morse code to deliver messages to the outside.

At that time, because of curiosity, there was a craze among her classmates to learn Morse code, and she also had some understanding of the principle of Morse code.

simply designed a simple one and handed it to Xu Tao, in which there were some secret notes for asking for help, reporting safety, and pointing out the direction to teach the people below.

And this way of tapping is to determine whether the other party is your own person.

Although it doesn't sound like much of a difference, it seems to be the same as before, but only those who have really learned her percussion method will know the difference.

It is also to prevent people from deliberately imitating it.

And Li Lei has only just learned this method, and she took the time to teach it on the way to Fucheng.

"Ann!"

Lin Yu whispered to the people outside, but the corners of his lips pursed into a straight line.

She thought she was the one who knew who Li Lei was.

However, for the sake of what he is looking for, I don't care about it for the time being.

The voices of the two were extremely quiet, and they were all clear by the ears and eyes of those who practiced martial arts.

Others couldn't hear it, but Ling Xi, who was close to Lin Yu, was startled by her sudden opening.

Lin Yu gently patted her back to reassure, and whispered in her ear, "Help me keep an eye on Ling Shuangyue, don't let her find out." ”

Ling Xi didn't know why, but he still leaned on Lin Yu's shoulder and looked at Ling Shuangyue cautiously.

Lin Yu knew too well that woman could do anything, and she could do anything to harm others.

If she really finds out the clues, with her Qingqi brain circuit, she may or may not be able to sue.

After Lin Yu pacified Ling Xi, another voice came from outside.

"Try to protect yourself, I will contact Lord Ling and rescue you before entering the East China Sea."

Lin Yu knew that since they had already caught up, their safety was not a problem.

It's just that she didn't breathe a sigh of relief for this, but said more solemnly, "I eavesdropped on them, our group of people should be the last batch of goods, and they will go to sea after handover." ”

Ye Linghan reacted instantly, and he also understood Lin Yu's thoughts.

After thinking about it, he said, "I will send a message to Lord Ling, you take care of yourself first." ”

Lin Yu responded, "Okay." ”

There was no sound outside, and Lin Yu whispered to Ling Xi's side and told her that Lord Ling's people had followed, and they would soon be able to send a message back to save them, so that no matter what happened, she should not act rashly and protect herself first.

Ling Xi leaned on her shoulder, nodded almost imperceptibly, and said softly, "With Sister Lin here, I'm not afraid." ”

Lin Yu knew that she was just comforting herself, after all, she was still a child, and she had never experienced such a big calamity, how could she not be afraid.
