Sean's team even made this kind of thing. It's amazing. Liu Jia and Wang Xin looked at each other, and then they started to catch up: "we'll help too."

When the two students who were responsible for building the signal tower saw Liu Jia and Wang Xin, their eyes showed a trace of vigilance, because it took a lot of energy to design it. Now it is being assembled and has not been officially put into use. The two students naturally have a trace of vigilance.

This is not because they do not trust Liu Jia's loyalty, but because the relationship between this simple signal transmission tower is too important to have any problems. Therefore, the two students in charge dare not be careless.

Liu Jia was careless. He didn't see the look in their eyes. Wang Xin was a little sharp. Before he approached, he suddenly stopped and said, "ah. Suddenly I remembered that Ji you was still lying and needed someone to guard. I won't go there."

Liu Jia wondered, "why don't you go and help? We have great strength and can help a lot."

Then he insisted on rushing forward. Wang Xin grabbed him and winked at him: "don't go there. When they need our help, let's go again. We promise to be on call."

Liu Jia was puzzled and said, "I think they need help now?"

Wang Xin grabbed Liu Jia's arm, hooked his shoulder, and pulled the man away.

See here.

The two students in charge of building the signal tower were relieved that the two newcomers didn't take the initiative to come and ask to join, which was also a good thing for them, so they didn't have to take the initiative to refuse.

Soon.

Two students in charge of building the signal tower, plus Li Yun and Bai Hui called from the stone house where Ji you stayed. The four students worked together to build a signal tower. The signal tower is very simple. There are only signal transmitting and simple receiving devices. The transmission distance is only 1000 meters at most. Moreover, to receive the signal here, we must carry the line on the side of the signal tower.

At present, limited by the simple facilities and materials of the competition venue, wireless signal transmission cannot be achieved.

In short, it sounds very chicken ribs.

However, this does not mean that the signal tower has no effect at all. On the contrary, it can play a great role as long as the line is laid in advance, cleverly hidden and not found.

Just ask, if you find the enemy's hiding place thousands of kilometers away, and then transmit the signal to the signal tower on the side of the station. The teammates on the side of the station are prepared in advance and set up an ambush, then the victory Libra of this battle must be inclined to their own team.

One thing, or a technological breakthrough, is often very difficult from 0 to 1, but it is simple from 1 to 10. Although the current transmission distance of the signal tower built by Sean's team is only 1000 meters, as long as the students responsible for building the signal tower continue to improve, it can soon be extended to 2000 meters, 5000 meters, or even 10000 meters

At that time, Sean's camp with the signal tower can communicate and communicate at will. The superiors issue orders and the subordinates can execute them at any time. The efficiency of the whole operation will be greatly improved.

The victorious Libra will tilt to Sean's team.

Nestled in the stone house, it seems that Ji you, who doesn't listen to things outside the window and is bent on taking care of her body, has listened to the conversations of Liu Jia, Wang Xin and several other Sean teammates outside the window and into her heart.

Ji pomelo's eyebrows were slightly raised. No wonder Sean couldn't help but didn't go out to find the league team after listening to his deception. The reason for daring is here.

The matter of the signal tower is so important that according to Sean's character, he must not trust to hand it over to other people. Therefore, he must take the team out to lay the line himself.

Moreover, the appearance of Ji grapefruit and his entourage slightly disrupted the rhythm of Sean and his entourage, causing the moment when they built the signal tower to move back a little. In addition, Ji grapefruit was acutely aware that Sean seemed to have confided in himself and completely trusted him, but he still didn't dare to completely relax his vigilance deep in his heart.

Ji pomelo touched his chin.

[hmmm -]

It's good to be vigilant

[what I fear most is people who seem to have no vigilance at all. It's hard to see what's written in his heart.]

Sean, it's very easy to deal with.

Isn't that vigilance?

Let's keep him vigilant all the time. It's even better to push the boat with the current and create more blinders to make him suspicious.

meanwhile.

Sean, who was leading two teammates and was rapidly circling within 1000 meters of the whole station, suddenly sneezed. He frowned and said, "is the weather getting warmer?"

A girl next to him felt it and said, "no, it's the same problem. I don't feel any change."

Sean touched his nose and said, "go on."

The line has been roughly laid before. Sean came out with two teammates this time to recheck it. If there is anything wrong, correct it in time, so that after the whole signal tower is built and really used, there is no need to worry about poor transmission.

The actions of the three members of the party are very secret. During this period, they have been carefully checked to avoid being found out their real purpose. These hidden lines are made with limited materials, and they can't do less. Therefore, they must be absolutely secret.

Suddenly——

"A sneeze -"

Even though Sean covered his mouth and nose, the center of his eyebrows twisted up and said, "what's going on?"

The girl was a little strange and asked, "monitor, do you have a cold?"

Sean frowned and said, "I don't feel anything wrong with my body." then, coldly, Sean sneezed again. Sean covered his mouth and nose and said, "I'll switch the position immediately. You bury the line in another direction and pay attention to hiding in time“

After several consecutive sneezes, his position was exposed. Sean felt something wrong, so he decided to retreat immediately and transfer a signal receiver originally laid there.

Sean dodged away in time. On the deserted mountain, Sean hid behind a large rock, rubbed his nose, and couldn't help saying, "who is cursing me behind my back?"

Off screen.

The onlookers wanted to chase Sean's ass and roar——

"You know the truth."

"Someone is cursing you."

"Someone is thinking about your head."

"Be careful, be smart, and don't be cheated again."
