Soon, the twin planes came to the sky over Tianfu District, Li Baoqiang lowered the nose of the plane, slowly descended to the Tianfu District compound, and then circled over Tianfu District for three weeks, turned around and flew in the direction of the Sword Pavilion Tunnel, about to return.

When he turned to leave, Li Baoqiang saw the crowd of people reveling in Tianfu District on the ground, and it is estimated that the people of Tianfu District saw their fighter jets and saw the Civil Defense Army's own air force, and these people fell into ecstasy.

Li Baoqiang manipulated the first five to shake the wings three times, which was regarded as a tribute to the subjects below, this is the plane etiquette he didn't know where he learned, seeing the people below swinging their arms again, cheering, greatly satisfied Li Baoqiang's vanity,

Seeing the action of No. 2 Junior Sect Five, and the No. 1 Junior Tutor Wuli accompanying him next to him, Huang Kai smiled bitterly,

Li Baoqiang is a cow, this is Huang Kai's heartfelt evaluation,

Li Baoqiang made a beautiful turn and began to return, but he was a little lost in the sky, and the course was a little uncertain.

Huang Kai knows that it is not so simple to be a pilot, and being able to drive to heaven does not necessarily mean that he is a qualified pilot.

Astronomy, geography, physics, machinery, mapping, meteorology and other majors, pilots must master, there is a saying in the previous life, the money spent to train a fighter pilot, you can use gold to make a statue exactly like yourself, this is true,

Huang Kai accelerated past Li Baoqiang's No. 1 Junior Sect Five, flew in front, and guided the No. 2 Junior Sect Fifth to start returning.

Blue sky and white clouds, mountains and mountains, the earth is vast, a beautiful river and mountain,

Li Baoqiang is also surging in his heart, how to develop and grow the Civil Defense Force in the next step, Li Baoqiang has a plan in his heart,

The two Chujiao Wuyi landed steadily on the highway one after the other, and when Li Baoqiang and Zhao Ying stepped off the plane, Huang Kai was already standing under the plane waiting for him.

Master Zhou Lin, Liu Junsheng, Li Jun, Wang Qiang and others rushed up, lifted Li Baoqiang up and threw him into the air, the crowd was excited, their commander created a miracle, and at the same time, these people were also venting their dissatisfaction with Li Baoqiang, because Li Baoqiang took off during the time, so that everyone suffered great torture in their hearts, and the feeling of great sorrow and joy and pain was really unforgettable.

Li Jun whispered a few words to Huang Kai, Huang Kai frowned, and hurriedly stopped everyone loudly, and gave Li Baoqiang a look to Li Baoqiang, who had just landed,

Li Baoqiang waved his hand at everyone knowingly: "Today's test flight was very successful, first tow the plane back for maintenance, and drink celebration wine tonight, who is that, Zhao Ying, you report to Captain Li Jun, you are the first flight student." ”

After Li Baoqiang finished speaking, he walked to the side with Huang Kai, and the group of soldiers behind him hula surrounded Zhao Ying at once, asking this and that, Zhao Ying's face was proud,

"There was an explosion in the Tibetan Soldier Cave, and I don't understand the specific situation, Wang Zhiming has already rushed over."

Huang Kai said worriedly, Li Baoqiang,

"I'll go over immediately, Chief of Staff, you rush back to Tianfu District immediately and take control of the Civil Defense Force, please."

Li Baoqiang held Huang Kai's hand tightly, and everything was silent,

The Tibetan Soldier Cave is the big granary of the Autonomous Region of the Civil Defense Army, and its status is very important, and there was an explosion there, and the two of them couldn't help but be nervous.

Li Baoqiang drove alone and ran wildly, and two hours later came to the Zangbing Cave in the Hope Zone.

Zhang Dajun, Wang Zhiming and Huayang, who looked sick, greeted Li Baoqiang's arrival at the gate of the Tibetan Soldier Cave.

Li Baoqiang and Huayang exchanged a few words, and went straight to the door of the laboratory, the laboratory has been protected, and the scene has not received much damage.

The inside of the laboratory is actually a stone cave, and the door is a plastic steel door and window, and now the plastic steel doors and windows have been blown up, and the debris is jumping everywhere.

Li Baoqiang walked into the laboratory, the room was also messy, as if it had been robbed, and there was no smell of gunpowder smoke in the air, which made Li Baoqiang very suspicious.

Huayang's injuries were not serious, but he was injured by the shock wave and vomited a few mouthfuls of blood, and there was no smell of gunpowder smoke in the air, which ruled out the suspicion of artificially installed explosives.

Li Baoqiang glanced around, looking at every point of suspicion,

Li Baoqiang then searched for the center of the explosion, it was obvious that the laboratory pool was the center of the explosion, and the sewer explosion should have been caused by the methane gas produced by the decaying materials.

Li Baoqiang was relieved, this point is similar to what Zhang Dajun reported just now, thinking that the installation of explosives can basically be ruled out.

Suddenly, Li Baoqiang reached out and touched the surface of some items, a layer of mist floated on the surface of each item, Li Baoqiang put his finger in his mouth and licked it, tasted the taste, a very familiar taste,

Li Baoqiang's heart moved,

"Professor Hua, have you done any experiments recently?" Li Baoqiang turned around and asked Huayang,

"Yesterday I just came back from collecting microalgae samples from other places, went back to the laboratory to check the microalgae cultured, and then went home, and I didn't have time to do experiments."

Huayang recalled yesterday's experience and shook his head, but looking at the sewer tank at the center of the explosion, he suddenly thought of something,

"Yesterday I saw a bottle of microalgae samples, which multiplied very slowly, and had no research value, so they were poured into the sink.

Huayang replied to Li Baoqiang nervously, as if he wanted to get something, as if the truth was in front of him, but he always couldn't grasp the key point,

"Chemistry."

Li Baoqiang knew it in his heart,

"Go find a plastic bag." Li Baoqiang turned back to Wang Zhiming and said,

Huayang and Zhang Dajun glanced at each other, not knowing which play Li Baoqiang was singing.

Wang Zhiming quickly returned, holding a black plastic bag in his hand and handing it to Li Baoqiang, with a burst of curiosity on his face.

"Everyone, the time has come to witness the miracle." Li Baoqiang smiled mysteriously,

Zhang Dajun and Wang Zhiming glanced at each other, their heads began to play tricks again, and Huayang seemed to understand something, thoughtfully,

I saw Li Baoqiang put the plastic bag mouth down and put it on the mouth of the exploding sewer, and the deflated plastic bag slowly filled and expanded, and finally formed a small balloon.

"Guys, crime scene replay begins."

The laboratory door in front of him has been blown to pieces, and the air is unobstructed, so Li Baoqiang dares to play with a heartbeat,

He motioned for everyone to flash aside, took out a lighter casually, approached the plastic bag, and only heard a small explosion with a "bang", and black debris flew all over the sky.

Li Baoqiang picked up a piece of debris and handed it to Huayang,

"Professor Hua, can you taste what the liquid on it tastes like?"

Huayang excitedly took the crumbs, saw the thin layer of mist, and guessed in his heart,
