A few people simply ate something, Li Mowu returned to the mouth of the canyon, picked up some branches and came back to dry, and made a bonfire to make a pile of coals.

Li Mowu added a branch to the bonfire and asked. "What if we come back again? Lejin can't come back, we can't stay here all the time. ”

Xijiang looked at the campfire quietly, and after a moment, he nodded, and said gently. "The light rain here is continuous, the temperature is extremely high, according to the current time conversion, the current surface of the river does not know whether it is or not, and it is impossible to turn back for a while. ”

At the same time, Qiu Yan raised his head and saw the gentle eyes of the slender old man, who was staring at him deeply.

"You mean, you're going into the swamp?"

"Since we have come to this point, it would be a pity if we turned back, putting aside Mr. Le's identity, don't you want to witness the legendary Sansheng Bluestone?"

Qiu Yan sat in place and was silent, the light around him was faintly dim, and after a while, he raised his eyes and looked at Xiao Li beside him, stood up and said. "I just want the trip to be quiet. ”

.....

Xijiang took out a yellow pill-like thing from his backpack and threw it into the charcoal pile, and soon a thick smoke slowly rose in front of everyone, and he told everyone that this was a distress signal smoke used in the field, which was better than signal flares, and just a few balls could burn for nearly three or four hours.

Qiu Yan and Li Mowu looked at each other and looked at each other, like this kind of wild way is still a little incomprehensible to the two of them, if this is placed in a combat mission, it is undoubtedly to tell each other where they are hiding, but the identities of the two sides are different, and their thinking is also different, and the two of them did not say anything.

Different colors of smoke represent different meanings, but they are all simple and easy to understand, this yellow represents the danger or search for people on the road ahead, etc., to move forward carefully, more complex communication, until Le Jin saw the smoke, he could not find a way to convey the past after giving everyone a response. Observing Lejin's whereabouts last night, the terrain is slightly higher than the camp, and it should be easy to see, and everyone should always pay attention to the swamp around, or whether there is a signal smoke response on the four walls, which is a very effective long-distance communication method.

Li Mowu added a cigarette ball every two hours, after the first cigarette was extinguished, there was no echo, Le Jin did not come back, and several people did not care, until the afternoon, when the second cigarette ball burned about half, suddenly Li Mowu screamed. "There is, there is!

Qiu Yan and Xijiang were discussing the itinerary, and when they heard Li Mowu's shout, they looked towards the swamp together, and before they noticed it at first, Li Mowu pointed to a certain place in the sky and shouted. "Over there, over there!"

Qiu Yan narrowed his eyes, only to see a puff of smoke rising from a distance, floating into the sky, the smoke was red, at first glance, it looked like a huge cockscomb snake, coming out from under the canopy of the tree far away. However, the corners of Xijiang's mouth were only half pursed, and suddenly the ground froze.

Because the place where the smoke rose was not the periphery of the swamp at all, nor the direction in which Lejin pursued last night, but the center of the basin where everyone was, the depths of this swamp.

However, what stunned Xijiang was that the signal smoke that Le Jin responded to was actually rising from the opposite direction, from behind the camp, in the center of the swamp, which meant that he was now in the swamp.

Li Mowu couldn't believe his eyes. "What's going on? What's going on in there?

Xijiang was afraid that it was a misunderstanding, so he immediately picked up the telescope to look, and when he saw that it was correct, the smoke would definitely not be caused by fire, because the color of the smoke was abnormal.

"Old man, this is strange." Li Mowu muttered.

"It's impossible, how did he travel through the past?.." Xijiang was also full of questions at this time.

"Could it be someone else's team?" Li Mo said martial arts.

"This is definitely not the case, these cigarette balls are all homemade by me, there are no ones on the market, I gave Mr. Le three different colors on the way here, just in case. ”

"That's weird, it seems that you made a mistake in the handover with Lejin. ”

Qiu Yan suddenly remembered that color could represent information transmission, and asked. "What does this red smoke mean?"

Xijiang raised his glasses again, looked in the direction of the smoke, and looked at it, his face suddenly changed, and he said awe-inspiringly. "Oh no, something happened to him. ”

"What's wrong?" Qiu Yan saw that Xijiang's face changed, but he didn't know what he meant, so he asked him to explain in detail.

"The color of the smoke has a simple meaning, the yellow smoke represents the danger ahead, you should move forward carefully, the orange smoke means stop moving forward and wait for confirmation, and the red smoke is more serious, indicating that you must not approach, and it is generally issued in an extremely dangerous situation to warn latecomers. Red smoke is rarely used in normal operations. But Xijiang is also a little hesitant, this kind of thing is also a temporary method, the use of the cigarette Lejin is not wrong to say, maybe the other party is wrong and confused. "It seems that we are going to set off early, the signal smoke can only burn for three hours at most, this time we go in, we can't rest, so we should try to travel as light as possible at a time, anyway, when we turn back, we will inevitably pass through here, so try not to bring anything we can. ”

After that, several people quickly moved and sorted out the mercenary backpacks that they had picked up in the canyon. Leave necessities such as gas masks, firearms, ammunition, GPS, etc. behind. Then Qiu Yan changed some of Xiao Li's heavier things into his backpack, Qiu Yan's marching weight was professionally trained by Heyue Island, and carrying a little more did not affect his speed at all.

Everything was in order, and they were just about to leave, when suddenly Li Mowu grabbed Qiu Yan and Xijiang again, and asked them to look up at the smoke in the distance.
