After learning from Xue Ziyan, I learned that this kind of test must go through multiple levels of constant standards and exceeding standards, and must have at least ten grades or more data, so it is inevitable that there will be unsatisfactory operation. But this initial test has fully met the design standards, and even exceeded 30%, which is indeed a good start.

After congratulating Xue Ziyan and others on their first victory, and telling Xue Ziyan and others to pay attention to their health, Ding Chi returned to school. Now it's off to a good start, he's more confident, he doesn't have to be on the scene all day, and he can't help technically. And it's June, so it's time to study and revise for the final exam.

The second test was carried out on June 8, and Ding Chi happened to participate in school activities on that day, which was set in advance, so he could not go to the second test site. However, he got the news at the first time, and the second test was completely normal, and the data was still stable, the voice quality was clear, and the rate was normal.

Xue Ziyan also said on the phone that he only needs to pass the three tests, and then it will be completely completed. Of course, this also implies another layer of meaning, if the three tests cannot be passed, then you have to re-check and fill in the gaps, and then test several times, and it is impossible to complete it at the end of June. Neither of them broke it, but they also tacitly understood it, full of antiquity and inevitably uneasy.

The days go on, and the countdown to the end of R&D is approaching. During the period, not only was there no abnormality in research and development, but Tiangong was also very beautiful, it was sunny all day long, and it didn't rain at all, Xue Ziyan said with a smile, "I don't have to endure the double test of fire and water."

The time was already in the middle of the day, and the three tests were getting closer and closer, taking advantage of the relaxed course of the day, Ding Chi arrived at the R&D site early in the morning. But as soon as he entered the courtyard, he was startled, there was a lot of water in the yard, as if it had just rained, and Xue Ziyan and the others were also busy with muddy water.

"The ditch behind the house got water, but it didn't get in. Without waiting for Ding Chi to ask, Xue Ziyan hurriedly stepped forward to speak.

Ding Chi took the shovel and followed the water: "Where did the water come from? ”

"It seems to be water from the house in the northeast corner, and I haven't even looked at it. Xue Ziyan was busy while talking, "In the morning, I had an upset stomach, so I went to the courtyard to get a tuba, but I heard the sound of "whooshing", and I didn't pay much attention to it at the time, thinking it was from someone else's house. But as soon as I squatted down, I felt that the sound was wrong, as if it was coming from the back of the house. I didn't care about squatting, so I turned to the back of the house and looked, and I was scared stupid, the ditch was full of water. ”

"Let me be so frightened, my stomach is gone, I quickly went back to get the keys, and called them up. When we opened a few rooms, thankfully, there was no water in them, so we took tools to change the waterways and open the canals. There was no water in the house, it was just a false alarm, so I didn't call you in time. ”

Ding Chi let out an "oh" and asked, "Which one is it? Why is it leaking?"

"I haven't looked at it, I'm just busy with what is in front of me. Xue Ziyan said, just go and take a look.

Ding Chi stopped Xue Ziyan and dealt with the stagnant water together.

The water from outside the ditch has been diverted, and outlets have been opened on the east and west sides of the ditch, and after about ten minutes, the water in the ditch has flowed away, leaving only the mud at the bottom of the ditch.

Let Xue Ziyan and the others hurry up their work, and Ding Chi went to the back of the house alone.

Although there was no water in the ditch, the water continued to flow, but to the ditch to the west. Along the direction of the water, Ding Chi walked slowly and came to a courtyard in the northeast corner of the source of the water source.

The courtyard door is locked, standing on a high place outside the courtyard and looking at it, the artemisia grass in the courtyard is high, the glass on the window is broken a lot, and the door is also locked. No wonder no one cares, it turns out that there is no one here for a long time. Then he couldn't help but wonder: since no one is moving, how did this water come from?

Whatever, you have to let someone fix it first, you can't just keep flowing.

took out his mobile phone and was about to dial, Ding Chi's brows furrowed suddenly, and he looked around, puzzled even more: There are two houses in the middle, why did they flow alone to the back of our house?

Putting away his mobile phone, Ding Chi returned the same way, and observed.

No wonder, the ditch led it. How can there be a ditch? How can it be in harmony with the current? The answer is self-evident.

During the return trip, Ding Chi also took a special look, and the two households in the middle should have been uninhabited for a long time, in fact, the houses on both sides of the R&D site were also empty. In this way, even if there is some movement at night, especially in the second half of the night, it is not easy to be noticed.

After returning to the courtyard, Ding Chi did not tell what he had just discovered, but inquired from the side. Sure enough, as they judged, Xue Ziyan and the others only drew the water from the ditch behind the house, and they didn't have time to find the source of the water, and now they are still puzzled. In addition, because a few people have been engaged in research and development since they came here, they have not understood what is going on around them, and they only feel that there are very few people.

Without delaying a few people's time, Ding Chi put on high rain boots, took a shovel, and arrived at the back of the house. Seeing that there was no one around, he came to the ditch along the edge of the ditch and gently shoveled the silt in the ditch. After a few shovels, I found that there was very little silt in the ditch, almost no weeds and stones, which was very abnormal, and it was obviously cleaned before entering the water. Who can be so kind? Is this a good heart?

continued to clean up quietly, and only after the entire hard bottom was cleared out did Ding Chi stop his movements and observe it again. After making sure that there was no one around, Ding Chiha lowered his waist, pulled the bottom of the ditch with both hands, looked at it for a while, and repeated this operation several times in a row.

After coming out of the ditch, Ding Chi returned to the dormitory, took off his rain boots, dealt with the splashed mud stains, washed his hands and face, and then took out his mobile phone and dialed the number.

After a short time, a voice came from the mobile phone: "Call so early, is there something wrong?"

"Zheng Ju, report one thing, I'll ......" Halfway through the words, Ding Chi changed his words again, "Are you going to the unit? ”

There was a silence on the phone, and a voice came: "Okay, you come here at half past eight, and I still have guests at nine o'clock." ”

put away the phone, spent another while, and then said hello to Xue Ziyan, saying "go out to do something", Ding Chi left the yard.

Not long after I walked out, a construction truck drove behind me, and there were several men with the word "tap water" sitting on the car, and the sound of conversation floated out of the open window:

"Why did the water pipe collapse? It doesn't look like it is aging, it is clearly a new stubble. ”

"Needless to say, I must have wanted to sell it secretly, but a lot of water flowed out after it was broken, and I was worried that someone would find out, so I scratched the girl. ”

"Zhente Niang's begging ghost, she fights any idea, and she is poor and crazy. ”

"I didn't expect that this kind of thing hadn't happened for many years. There are a lot of empty houses here, and if they are all out like this, it will be enough for us to be busy. ”

"Go back and report back to your head and see what to do. Damn. ”

The car passed by, and the scolding of several people in the car gradually faded away.
