Tang Yi returned along the original route and headed to the location where the foreign aid team had previously studied.

After dusk ended, it was dark very fast.

After following the road, the sky quickly darkened. There were no street lights in the village of Maze, and the visual range was rapidly reduced. The darkness gave Tang Yichang a layer of protective color.

——Xiao Ni and Si Fengmian did not have Si Sheng’s forward consciousness and did not prepare to go on night vision goggles in advance.

"Brother, will you lose this way?" Si Fengmian touched Xiao Ni's arm and asked in a low voice.

Xiao Ni was very calm and said, "This is the direction of the research point."

"Um?"

Si Fengmian then woke up and thought about paying attention to the route.

After a pause, Xiao Ni said again: "The branches of the road behind are dead ends. Unless he chooses to climb over the wall after entering a dead end."

"Then where does he want to go?" Si Fengmian frowned suspiciously, "Go and continue to do the so-called research?"

"I don't know." Xiao Ni paused for a moment, looked at the back that disappeared from the corner ahead, followed, and said, "But if you think about it anymore and don't pay attention to the route, it will take a minute to get lost."

"……oh."

Si Fengmian responded quickly.

After restraining his random guessing, Si Fengmian's mind was shocked and he quickly began to remember the route.

Can--

What is frustrating is that even though they hadn't seen Tang Yi for a while, when they arrived at the research site one after another, they saw Tang Yi carrying the instrument for a detection.

He held the instrument in his hand and stood in front of a wall, observing and recording.

There were a few camp lamps nearby, full of light and even a little dazzling.

Xiao Ni and Si Fengmian subconsciously looked at each other.

"Click."

Tang Yi put the instrument in his hand on the ground and made a slight sound.

Then, Tang Yi turned his head, glanced at the two of them, and said indifferently: "Come on, come here and help."

“…”

“…”

The two looked at each other again.

Si Fengmian wants to step forward.

However, Xiao Ni suddenly stretched out his hand and stopped Si Fengmian. He turned his head, shook his head gently at Si Fengmian, and then walked towards Tang Yi himself.

Help to get started.

His and Si Fengmian's small actions were not hidden, but they were actually very clear.

Tang Yi saw it all.

However, there was no reaction. Tang Yi pushed his glasses up, looked at Xiao Ni again, and then began to arrange for Xiao Ni to do things.

Si Fengmian looked around for a while, and after confirming that nothing was wrong, he took a piece of information and sat next to him and looked around. From time to time, he looked at Xiao Ni and Tang Yi for a few glances, and didn't know what he was measuring.

Not long after.

People from the foreign aid team arrived one after another.

The working environment also became noisy.

However, Tang Yi still did not make any unusual moves, like a work machine, with basically no other communication with people except work content.

At half past ten, they finally finished work.

Xiao Ni packed up, came to Si Fengmian, and said, "Let's go."

"oh."

Si Fengmian, who had been sitting all night, had his legs numb. He put the information together, stood up, and picked up the stool and folded it.

Everyone around them is busy with their own affairs.

Taking advantage of the lack of people, Si Fengmian looked at Tang Yi and asked Xiao Ni in a low voice: "Is there any abnormality?"

Xiao Ni paused for a second and said, "No."

"so."

Si Fengmian was obviously a little disappointed.

He took off his backpack and put the folded stool inside. He noticed that Xiao Ni's eyes were always on him. He paused and understood, "Meng Ji was not strange either. He had never left, and had been doing his own thing."

Because "Tang Yi" and "Meng Ji" are too eye-catching, they are both targeted "supervision".

——Of course, you should not completely relax your vigilance against others.

Whoever left alone, how long it took, and where he went, had a clear idea in his heart.

"Um."

Xiao Ni nodded slightly.

As long as they are willing to act like this, they can achieve "no traces".

However, he still hasn't figured out what kind of reason it is that Tang Yi would rather make them suspicious than choose to do it at that time.

"Let's go back first, let me tell you." Si Fengmian put his backpack on his shoulder.

"Um."

Xiao Ni refused to comment.

Although the two brothers were about to leave, they did not take the lead, but stayed behind the team, as if they were dragging their feet.

I was woken up at five o'clock. I have been working until now. The foreign aid team still has to walk back with heavy instruments on their backs. I am exhausted at this moment and no one has the strength to gossip.

but--

Before the last light went out, an associate professor suddenly walked up to Tang Yi with a record book and asked, "Tang Yi, did you record this?"

Tang Yi looked back and said, "Xiao Ni."

"Oh," the associate professor pushed his glasses, nodded, and muttered as he turned his head to leave, "I said why can't my handwriting match?"

Tang Yi didn't say anything else, picked up his instruments and backpack and followed him back.

Xiao Ni and Si Fengmianxin had doubts, but they couldn't think of any reason.

*

When I returned to the camp, it was almost twelve o'clock.

The two of them live in the first camp, and it is no problem to find Mo Shangyun. After all, Mo Shangyun lives in the first camp. But it is too obvious if they want to find Si Sheng and Ling Xize in the third camp.

Besides, it's getting late.

Can--

Mo Shangyun, Si Sheng and Ling Xize directly dispelled their doubts.

Because, as soon as they arrived near the tent, they saw the lights inside and some sounds of reporting numbers came from inside.

The two looked at each other suspiciously for a second, then opened the curtain and walked in. They suddenly saw Mo Shangyun, Si Sheng and Ling Xize sitting together. They got a small round table and a pair of poker from somewhere, and were fighting against the Landlord at this moment.

Xiao Ni: "..."

Si Fengmian: "..."

Throwing out a pair of A's, Mo Shangyun greeted them, "Are you back?"

Si Sheng didn't raise his head, "You can take the night snack by the bed."

"Go to have a midnight snack first," Ling Xize glanced at the two of them and said casually, "When eating, you say."

"Why are you here?" Si Fengmian put down his backpack, a little confused.

Xiao Ni walked over, picked up a bottle of mineral water from the box, unscrewed it, and threw it to Si Fengmian.

Then, unscrew another bottle for yourself.

Si Sheng supported the chin with one hand, threw out a bomb, and then spoke leisurely: "Listen to Ding Jing, you two last night--"

"puff--"

"Ahem."

Si Fengmian squirted out a sip of water.

Xiao Ni choked himself.

Seeing the reaction of the two, Si Sheng was slightly stunned, "You two really fight?"

“…”

“…”
