Xiao Hei ran very fast, but Xia Ruofei, Guo Zhan, and Tian Feilong were all experienced special operations elites, and they could still easily keep up. Pen, fun, pavilion www. biquge。 info

Liang Qiming's laboratory is located in the corner of the campus, and not many people pass by here, so no one notices the strange scene of three people running wild with a dog.

However, Xiao Hei ran out for about two hundred meters and stopped, sniffing in place, seemingly hesitating, not sure which direction to go.

Tian Feilong gasped slightly, with a look of disappointment on his face, and said, "The police dog sent by the special police to support yesterday almost chased this position and lost its target, huh...... Xiao Hei chased more than ten meters more than yesterday's police dog. ”

Xia Ruofei said calmly: "It's possible that the gang used some method to cover up the smell on their bodies around here, but don't worry, they can't completely cover it up, especially the smell of the chemical reagents on Professor Liang's body is very strong, and Xiao Hei is still working hard!"

Guo Zhan nodded and said, "Blood wolf, whether you can find useful clues depends on Xiao Hei's......"

The three of them all stared closely at Xiao Hei's movements, only to see Xiao Hei hesitate in place for about half a minute, and then finally determined a direction and continued to run forward.

However, this time it was not as sure as it had just been at the back door of the lab, and the speed of running was a little slow, and he stopped from time to time to sniff the smell to determine the direction.

Xia Ruofei and the three of them followed Xiao Hei closely, stopping and stopping all the way, Xiao Hei's travel speed was getting slower and slower, and it was obvious that the smell was gradually fading.

During this period, I also changed directions several times, and I felt that the group's forward route was irregular, and sometimes they even took a short way back.

In this way, after walking forward for more than a hundred meters, Xiao Hei stopped.

In front of it, there was a sewer manhole cover, and it sniffed around the manhole cover for a long time, walked around the manhole cover a few times, and whined at the manhole cover in a low voice.

Xia Ruofei glanced at Guo Zhan and Tian Feilong, and said, "Wolf King, it seems that that group of people entered the sewer from here yesterday. ”

Tian Feilong nodded and said: "It's very likely, many surveillance cameras on the campus, including several cameras at the school gate, have not captured the whereabouts of this group, except for going underground, I can't think of any other way for them!"

After speaking, Tian Feilong came to the sewer manhole cover and squatted down, looked carefully for a while, looked up and said, "It should be right! This manhole cover has obviously been opened and put back in the near future, and it does not completely match the old traces!"

Tian Feilong is also an expert in trace science, after the sewer manhole cover is opened, even if it is carefully put back, it is impossible to be exactly the same as the position before it was opened, even if there is the slightest deviation, it will leave clues.

"Let's go down and continue to track!" Xia Ruofei said without hesitation.

Guo Zhan stretched out his hand to stop it, and said, "Blood wolf, wait until I call the other comrades over first, it's too dangerous to go down rashly like this!"

Tian Feilong asked a little puzzled: "Captain, nearly twenty hours have passed, and those people will still be hiding in the sewers, is it unlikely?"

Guo Zhan said solemnly: "It's not that there is no such possibility, we can't fight a war for which we are unprepared! Yesterday's lesson is profound enough, and I don't want any more comrades to shed blood and sacrifice!"

It seems that the sacrifice of Lao Luo's squad leader has a great impact on Guo Zhan, and in the eyes of Xia Ruofei and Tian Feilong, Guo Zhan is a little too cautious.

Xia Ruofei thought for a while and said, "Flying Dragon, what the Wolf King said makes sense. The most dangerous places are the safest, and it is indeed possible for this group of people to take advantage of our psychological blind spots and hide in a corner of the campus in the first few days......"

Guo Zhan heard that Xia Ruofei also agreed with his point of view, so he nodded, and was about to take out his confidential mobile phone to contact several other team members.

However, Xia Ruofei changed his words at this time and continued: "Wolf King, but I don't think things can be delayed, the possibility that the gang is still hiding in the sewers exists, but it is extremely small, we can't delay the fighter because of a small probability event." Besides, this time we are prepared, and we will never be caught off guard like yesterday, what do you say?"

After speaking, Xia Ruofei looked at Guo Zhan quietly, waiting for him to make a decision.

Now that Xia Ruofei has been temporarily recalled to the army, he still carries that official document in his arms! In a legal sense, Xia Ruofei has now resumed his status as a soldier, and he took 10,000 steps back and said, in case Xia Ruofei encounters misfortune in this mission, it will be counted as an active soldier who died in the war, and the military flag can be stamped at the memorial service, and there is no suspense in awarding the title of revolutionary martyr.

However, since the identity of the corporal of the lone wolf commando has been restored, it is natural to accept the leadership of Guo Zhan, the supreme commander of the lone wolf commando, if Guo Zhan insists on not agreeing to go down the well, then Xia Ruofei cannot disobey the order.

Guo Zhan stared at the manhole cover, his face changed, obviously weighing Xia Ruofei's suggestion, Xia Ruofei and Tian Feilong both stood quietly beside him, not interfering with Guo Zhan's thinking.

After a while, Guo Zhancai nodded and said, "Okay! Let's go down first! But now that there are new clues, several other comrades must also rush over immediately, I will contact them first, and then we will go down the well!"

"Understood!" Xia Ruofei nodded heavily.

Soon Guo Zhan contacted the other commandos who were on standby through a confidential mobile phone, and asked them to quickly rush to Sanshan University.

Then the three of them were ready to open the manhole cover and enter the sewer.

Xia Ruofei walked to the side of the manhole cover, and Tian Feilong also immediately came over to prepare to help - the workers have special tools to open the manhole cover, and it is easy to lift the hole on the manhole cover by hooking it, and now without tools, even if their strength is much greater than that of ordinary people, it is not easy to lift it if there is no force.

However, Xia Ruofei waved his hand to indicate that he didn't need it.

I saw him squat down, pick a small gap on the edge of the manhole cover with his fingers, push it hard to make the gap as big as possible, and then put his fingers in and lifted the manhole cover up with a slight force.

Then it was simple to have a force point, Xia Ruofei grabbed the manhole cover with one hand, and easily lifted it up and put it aside, as if he was carrying a ball of light cotton wool in his hand.

Guo Zhan glanced at Xia Ruofei with some surprise, and said in his heart that this kid not only did not regress after retiring from the army, but also seemed to have a lot more strength!

Xia Ruofei patted Xiao Hei's head and said, "Xiao Hei, continue to track the smell after you go down, but there may be enemies inside, remember not to make any sound!"

Xiao Hei had already opened his mind, and immediately nodded when he heard this.

Guo Zhan and Tian Feilong couldn't help but be secretly surprised when they watched from the sidelines, it was really not easy to train the earth dog to be as humane as Xiao Hei!

After Xia Ruofei finished speaking, he reached out and hugged Xiao Hei, ready to drill into the sewer.

Seeing this, Guo Zhan shouted: "Blood wolf, wait a minute! There may be danger down here, I'll take the lead!"

This is also the tradition of the Chinese army, when there is danger, the commander always takes the lead.

Xia Ruofei said: "Wolf King, after going down, I mainly rely on Xiao Hei to track down, and it only listens to me, so I must be at the front." ”

This reason is very sufficient, Guo Zhan can't refute it, he took out a pistol from his waist after a little groaning, handed it to Xia Ruofei and said: "The main equipment is in the hands of other comrades, you can use this gun!"

Being at the front is naturally the most dangerous, and Guo Zhan also handed over the only weapon he carried with him to Xia Ruofei.

After Xia Ruofei took the pistol, Guo Zhan took off his coat again, preparing to give Xia Ruofei the body armor he was wearing inside.

Xia Ruofei hurriedly waved his hand and said, "Captain, you don't need body armor!

After speaking, Xia Ruofei put the pistol in hand, and then sat at the mouth of the sewer, holding Xiao Hei with one hand, and grasping the ladder at the edge with the other, and quickly got into the sewer.

Xia Ruofei is very confident in his current strength, even if he is caught off guard, his unusual reaction speed will definitely allow him to avoid danger in time, but Guo Zhan and their body armor is equivalent to an extra guarantee, so he resolutely does not accept this body armor.

Guo Zhan didn't hold it, Xia Ruofei had already gotten into the sewer, he didn't dare to slack off, and hurriedly entered the sewer with Tian Feilong one after the other.

Tian Feilong, who fell last, did not forget to move the manhole cover that was put aside by Xia Ruofei to cover it, so as not to accidentally stumble and fall in when teachers and students passed by.

There was a very unpleasant smell in the sewer, Xia Ruofei frowned slightly, put his hand into his bag, and actually took out a dozen disposable masks from the Lingtu space, took three of them and put them on top of each other, and the smell was slightly reduced.

He gave the remaining masks to Guo Zhan and Tian Feilong.

Guo Zhan said with some surprise: "Blood wolf, the equipment is quite complete!"

Xia Ruofei grinned and didn't explain too much.

As for Xiao Hei, he can only endure it, and there is no mask suitable for his specifications, and Xia Ruofei has to rely on him to track the smell!

There is also a shallow layer of sewage in the sewer, which is very disgusting to step on. However, for Xia Ruofei and the three of them, they have experienced many times in a much harsher environment than this, and this situation is not trivial at all.

However, Xiao Hei has always lived in the picturesque aura of the Lingtu space, as soon as he entered the sewer, especially when he stepped on the sewage, he was very uncomfortable at first, and after a while, he reluctantly walked forward.

Guo Zhan and Tian Feilong are equipped with multi-functional combat watches, which can achieve simple air monitoring functions, and if the air quality in the sewer is seriously life-threatening, the watch will immediately vibrate and alarm.

The stench in the sewer is very strong, and it also causes a lot of interference for Xiao Hei to distinguish the direction.

It sniffed and hesitated for a moment before choosing a direction.

This sewer extends in all directions, and if Xiao Hei didn't lead the way, Xia Ruofei and they wouldn't have been able to find the way forward for that group.

Xiao Hei walked in front, and Xia Ruofei and the three followed closely.

The three of them consciously lightened their steps, and Xia Ruofei and Tian Feilong also held the loaded standard pistol tightly in their hands, paying attention to the situation ahead at any time.

In this dark and narrow environment, once you encounter the enemy, the situation will be very dangerous, even if the opponent shoots indiscriminately, it is likely to be hit by stray bullets.

They didn't even hit the flashlight, they just put a small fluorescent sticker on Xia Ruofei's back, and pushed forward one by one.

Xia Ruofei has excellent eyesight, and he has quickly adapted to the environment of the sewer, so he can easily keep up with Xiao Hei without lighting, which also makes Guo Zhan and Tian Feilong secretly surprised, feeling that after Xia Ruofei retired from the army, it seems that his abilities in all aspects have become stronger.

Xiao Hei stops and goes, and when he is unsure, he will return to a section and go to the fork to judge the direction again.

The three of them made a zigzag in the sewers for about seven or eight hundred meters.

The special combat team members are generally very sensitive to the sense of direction, and although they have turned around in the dark environment several times, they can still roughly judge that they are now about 500 meters away from the southwest of the experimental building.

Finally, Xiao Hei came to a place and stopped, and whined softly at Xia Ruofei a few times.

Xia Ruofei saw at a glance that there was a vertical upward passage where Xiao Hei was staying, and a ladder was also installed on the inner wall, obviously this was a sewer mouth.

Xia Ruofei hurriedly asked softly, "Xiao Hei, what do you mean...... The men went up from this well?"

Xiao Hei nodded immediately.

Guo Zhan and Tian Feilong also quickly followed, and now they were basically sure that the group was not hiding in the sewer, so Tian Feilong also immediately turned on the flashlight and checked near the exit.

Soon Tian Feilong shouted: "Captain, Xia squad leader, Xiao Hei's judgment should be correct, there are traces of trampling on the inner wall of this place, and it should be left recently." ”

Xia Ruofei also glanced over, nodded and said, "If I'm not mistaken, it should be Professor Liang's intention to stay." ”

Guo Zhan and Tian Feilong nodded in agreement at the same time - that group of people can sneak into the territory of Huaxia and rob Liang Qiming under the nose of a lone wolf, they must be the top special warfare masters in their country, and naturally it is impossible to leave such obvious traces on the inner wall when they go up the ladder.

The only possibility is that Professor Liang Qiming took advantage of the dark environment and pretended to step on the air without them noticing, so that he would leave these half footprints on the inner wall.

"Let's go up!" Guo Zhan said.

Then he stepped on the ladder first--now he didn't need Hei to lead the way, and he didn't know if there would be any unknown danger outside, so he took the lead as he could.

Xia Ruofei didn't rob him, so he waited at the bottom of the well with Tian Feilong.

After Guo Zhan climbed up, he vigorously opened a gap in the manhole cover, carefully observed it, and then pushed the manhole cover open and climbed up quickly.

After a while, Guo Zhan poked his head in and made a safe gesture towards Xia Ruofei and Tian Feilong.

Xia Ruofei immediately carried Xiao Hei up the ladder, and Tian Feilong followed.

Soon the three of them came to the ground, and Xia Ruofei quickly observed the surrounding environment.

This sewer mouth is located on a quiet forest path, far away from the teaching buildings and laboratories, and there are certainly not many people passing by here.

Xia Ruofei patted Xiao Hei's head and asked, "Xiao Hei, can you still trace that smell?"

Xiao Hei sniffed carefully, then barked twice at Xia Ruofei, and continued to run towards the grove.

Xia Ruofei's eyes lit up, and he hurriedly followed with Guo Zhan and Tian Feilong.

This grove is not big, and soon Xiao Hei passed through the forest, and as soon as Xia Ruofei and the three of them got out of the woods, they saw a building in front of them.

"Canteen?" Tian Feilong couldn't help but say to himself.

It turns out that coming up from the sewer mouth and walking through this grove will lead to the second cafeteria of the old campus of Sanshan University.

Xiao Hei's tracking ended in an open space on the side of the second cafeteria, and then he completely lost his smell, and no matter how hard he tried, he couldn't find his direction.

Is the clue broken again? Xia Ruofei frowned and pondered.

Suddenly, Xia Ruofei's eyes lit up and he shouted, "I know! I know how these people escaped! Haha! Xiao Hei, you have made a great contribution!"
