Ouyang Zhi didn't have time to think about why Chen Yan stabbed him suddenly, when he turned around, he saw that Chen Yan's eyes that had been numb were showing pain and struggle at the moment, and after struggling, he couldn't care about the wound on his waist that didn't stop bleeding, he just wanted to confirm whether his Yan Yan was really back. And because of that, there was that poignant hug.

"Is it really you?" Ouyang Zhi held Chen Yan's face and looked into her eyes, afraid that it was his own fantasy just now.

Chen Yan's current mind was chaotic, but before she could sort it out, all her thoughts were focused on the dazzling bright red.

"This, this is what I did? Why? How could I ......" Chen Yan didn't respond to Ouyang Zhi's affectionate gaze, she muttered incoherently, but the next moment, her actions once again exceeded everyone's expectations, and it also made the person in front of the monitor gasp fiercely.

No one knew whether Chen Yan's hands had just wanted to touch Ouyang Zhi's wound, or if they had already been controlled again when she was muttering. They only saw that the pair of trembling and thin hands had grasped the handle of the knife at this moment, and pulled it out vigorously, bringing out a parabolic trajectory of flying blood. After pulling out the knife, Chen Yan strode forward, holding Ouyang Zhi and falling backwards, and the two fell into the deep moat together.

Everyone on both sides of the river ran as fast as they could, but they could only watch the two of them fall, splashing several meters high. The few people who ran in front couldn't care about anything else, they jumped up and quickly swam towards the place where Ouyang Zhi fell after falling into the water.

"Hurry up! Go down a few more and expand the search range by 20 meters. Lang Lang was the first to rush over. The old housekeeper went out of the city, Qin Qin has been in the research center, although it has been notified, but it will take a little time to come over.

It's not that Lang Lang doesn't want to go into the water, his ability is fire, and he can't play any role in the water, and maybe he will be restrained. Moreover, the scene needs someone to command, and if even he goes into the water, or loses his cool, then the rescue work will be even more difficult.

The underwater mechanisms have all been shut down, but there is no guarantee that Ouyang Zhi and them were not injured by the mechanisms before they were closed. In addition, Ouyang Zhi had already been severely injured before entering the water, and Lang Lang didn't dare to think at all, what would they do if they didn't find Ouyang Zhi?

It has been 10 minutes since Ouyang stopped entering the water. The number of people who entered the water has increased from a few at the beginning to hundreds now, and some search-type machines and equipment have also been brought over by the speed-type abilities and put into use. Lang Lang expanded the search range from 10 meters and 20 meters at the beginning to 100 meters. But it didn't work. They didn't find any trace related to Ouyang Zhi or Chen Yan, and even the blood-stained water that Ouyang Zhi could still see when he first entered the water had already been washed and restored to its original color.

"Do you want to extend the search range by 100 meters?" Qin Qin also rushed over, and his breathing was still calm. He and Lang Lang are now looking at the screen connected to the underwater sonar detector, and within a search range of 100 meters, there is no other life information except for the searchers. That's why Qin Qin suggested expanding the scope of the search.

However, the water in the moat is not living water, but was artificially created during the construction of Doomsday City, and the water inside is fed from an underground river 2,000 kilometers away. In order to prevent the survival of underwater life, they blocked the entrance and exit of the river after the amount of water reached the specified target, and sprayed the water with drugs that can kill all aquatic life on several occasions. Make sure that this moat doesn't turn around and threaten the inhabitants of Doom City when the apocalypse comes.

Therefore, the river will not flow, Ouyang Zhi was seriously injured when he entered the water, and he fell from the bank of the river at a height of nearly 30 meters, and he also carried Chen Yan's weight. Therefore, according to the orbit, his position should be perpendicular to the fall point, and even if there is an error, this range should not exceed 10 meters. Therefore, when Lang Lang took over the on-site command, his first order was to determine the 10-meter search range. Then, when there was no news, and the manpower and equipment were in place one after another, Lang Lang expanded the scope of the search.

But now, they've expanded their search range by five times. 100 meters, whether in terms of probability, theory, or otherwise, is far beyond what it should be. Therefore, Qin Qin's proposal to expand another 100 meters is not even sure of himself. However, what if, what if, Ouyang Zhi really stayed away from the fall point? If they persistently speculate according to the data, will Ouyang Zhi miss the best rescue time because of this? And if they expand the range, even if they increase the number of searchers, will they miss Ouyang Zhi because of the expansion of the range, or will they miss the relevant traces?

Not only Qin Qin, who made the suggestion, couldn't be sure, but even Lang Lang was also in a dilemma. It's not that he hasn't thought about expanding the range, otherwise he wouldn't have gone from 10 meters to 100 meters. However, his focus is on time. It's been 15 minutes! Even if Ouyang Zhi relied on the ability of the Ability, he could hold on a little longer, but his injury would definitely greatly shorten the time he could have held out. So this node is basically the limit. If it drags on any longer, even if they can find Ouyang Zhi, it is by no means optimistic.

"Expand another 50 meters. Then go down to three groups. No matter how worried and dilemma he is, Lang Lang must also make a quick decision.

"Notify the reservoir dispatch room, and open the gate to release water in 5 minutes."

If expanding the search scope was Lang Lang's uncertain decision, then now this order, Lang Lang is even more burdened with a great responsibility. The area where Doomsday City is located is not a place with plenty of water. At that time, they surveyed a lot of places, and it was the underground river that could be used and developed as far as they could. Other underground rivers are farther away, not to mention completely undeveloped, but manpower, material resources, and financial resources are very heavy burdens, and most importantly, there is too much time.

The construction of the moat's infrastructure and irrigation facilities were completed before the apocalypse, but the irrigation and filling of the moat began after the apocalypse. And now, not to mention that the underground river is basically dry, the water source must not be drained again, even the mutated creatures in it, so they can't use it rashly again.

The role of the moat is very important, although it is not only dependent on the river water. But once there is no river water, then the mechanism inside will not say that it will lose its effect, but the effect will definitely be greatly reduced, and it will definitely not be able to prevent people!

Lang Lang made this decision without consulting anyone. Once the moat has an adverse impact and loss on Doomsday City in the future, Lang Lang will become the target of public criticism. Unless, today he can successfully find Ouyang Zhi, and it is Ouyang Zhi who is alive! (To be continued.) )
