Xiao Wu is Wang Yao's portable AI, and at this time, no matter how Wang Yao calls there, there is no signal.

"What's the matter, the AI doesn't recognize the owner?" Drew clapped his hands to watch the excitement, "Don't let me say it, you were also abandoned by Ju'an City." ”

Jiang Yilang walked around the desert and was already disgusted with AI: "Wang Yao, don't call, be careful that AI leaks our target!" ”

"Nonsense, they're waiting for me to come back and study the latest ballistics." Wang Yao didn't want to give up, and looked at the current map through her watch, "There will be a patio on the wall along this point, and this patio is an energy release hole!" ”

"What is an energy release hole?" Jiang Yilang and Drew know too little about Ju'an City.

Wang Yao checked the equipment on his body and put on the optical camouflage again: "There are countless energy release holes under Ju'an City, which are used to discharge the exhaust gas released by the Divine Fruit, you should know the existence of the Divine Fruit." ”

"Divine Fruit Exhaust?" Jiang Yilang was surprised, "Ju'an City has an excellent environmental index, how can there be exhaust emissions, hasn't it reached 100% treatment?" ”

Wang Yao snorted: "You who deceived children also believe that while the Divine Fruit gives humans endless energy, it also produces a considerable amount of exhaust gas, which is only discharged through the energy release hole to the outside of the wall of liberation. ”

"But the nature outside the Wall of Liberation......" Drew wanted to say that the environment outside was good, but he was silent at the thought of the desert outside the Wall of Creation, "Could it be that it is directly discharged into the Wall of Liberation?" ”

Jiang Yilang suddenly realized: "All the exhaust gases are discharged into the desert, is this the reason for desertification?" ”

"Instead of speculating here, why don't you follow me to the underground energy room." Wang Yao said and leaned out and jumped off the city wall first, "There are more AIs in the city, pay attention to the use of optical camouflage." ”

The three of them borrowed a rope gun and went all the way down, and the outer perimeter of Ju'an City was pitch black, with nothing but the occasional flashing AI guard lights.

In the same few minutes, the three of them managed to reach the bottom of the wall. There are pipes all over here, and one of the pipes has an opening that allows just the right amount of access.

Wang Yao took the lead in drilling in, and there was a faint red light emitting from the pipe: "The underground energy room is directly below Anhe Hospital, we can go to the side room like this, and we can reach my office through the ventilation duct." ”

Jiang Yilang turned over and noticed that the pipe was not at the end when it reached the bottom of the wall, and it was really extending outside: "The exhaust gas was really discharged to the wall of creation." ”

"Damn, is the desert really man-made?" Drew was still sighing, only to see a thick black smoke rushing in front of him, "Look! ”

"Put on your cloak!" Wang Yao reminded and pulled Jiang Yilang to seal the gap in the cloak, "Quick, quick!" ”

Drew couldn't react, inhaled black smoke in one breath, he felt hot in his lungs, his chest was uncomfortable, and his mouth was full of blood after coughing twice: "It's uncomfortable." ”

Jiang Yilang pressed Drew and put the cloak on him: "What are these ingredients!" ”

"A heat source reaction stronger than the sun." Wang Yao analyzed these exhaust gases, "If the concentration is reached, it can kill people in a few seconds." ”

Jiang Yilang was quite angry: "Why is this exhaust gas emitted, isn't it after any treatment?" ”

Wang Yao led the way in front, and he was already accustomed to this kind of anger: "It's not that you don't deal with it, but there is no way to deal with it, and the exhaust gas released by the Divine Fruit can't be dealt with by human technology at all." ”

"Then just discharge!" Drew pounded his hands on his chest and kept complaining.

The three of them walked along the pipe for a long time, only to find that the red light of the divine fruit was getting brighter and brighter, and suddenly they heard the sound of some human activity in front of them.

Wang Yao lit up the optical camouflage: "The energy room is in front, and you may see a lot of staff, who are from Anhe Hospital like you." ”

"We're outcasts." Jiang Yilang also clicked the button and walked gently in the pipe, "The sound of carrying is very noisy, there should be a lot of people." ”

Drew eased from his cough and walked behind tremblingly.

Wang Yao took the lead and walked out of the pipeline, and in front of him was a large warehouse, in which were metal shelves on various floors, and the shelves were neatly arranged with divine fruits.

Jiang Yilang and Drew had seen the Divine Fruit, but now the scale of this warehouse was far greater than that of the Underground Abyss.

In other words, humans use the Divine Fruit to a higher degree than the Camel Man: "Director Hash told me that one Divine Fruit can stimulate the entire Indulgence Cabin, what are so many Divine Fruits going to do?" ”

"The energy released by the Divine Fruit has promoted the rapid development of human science and technology." Wang Yao pointed below, and many guys wearing white chemical protective suits went back and forth.

Seeing that they were orderly but surprisingly quiet, Wang Yao said: "The establishment of the entire Anhe Hospital has to rely on the Divine Fruit. ”

Jiang Yilang stared at everything below, those guys had no language to each other, let alone eye contact, just doing their own things very mechanically.

"I can't imagine that there is such a working mode under Ju'an City, don't these people feel bored?"

"Work rules, if you don't enforce them, you'll be banished." Drew pointed to the Divine Fruit, "The energy is transmitted to the ground through certain pipes, and the exhaust gas is sent out through a simple exhaust device, without any treatment. ”

"What are the top brass considering, and this is not the way to go." Jiang Yilang clenched his fists and knocked on the handle of the corridor involuntarily.

"Bell!" A voice resounded throughout the ground.

Drew touched his heart and raised his fist to hit Jiang Yilang's head.

"Do you want to bring someone to arrest us?" Wang Yao hurriedly dragged Jiang Yilang away, but the people below didn't look up at all.

Jiang Yilang gasped and secretly rejoiced: "It seems that they are all workaholics, this sound can't attract them, Wang Yao, let's go to your office to have a look." ”

Wang Yao glared at him for a moment and began to look for a path to the ballistic laboratory: "At this point, those old guys have already rested, and I am usually the only one working in the office. ”

"You're a workaholic, too." Jiang Yilang followed Wang Yao to climb up another pipe, and in the highly developed Anhe Hospital, these ordinary exhaust pipes became a blind spot for monitoring.

Of course, such blind spots can only be found by engineering talents like Wang Yao, and basic workers like Jiang Yilang can't go to these places.

With various climbs and jumps, Wang Yao suddenly stopped above a closed pipe.

She pulled a small black square out of her trouser pocket and turned on the button: "This pipe is the exhaust gas link pipe in my office." ”

"What is this?" Jiang Yilang had never seen such a small box, "Can you cut the pipe directly?" ”

Drew is a little bit of a mechanic: "Nonsense, this is a particle detector that can penetrate through metal materials." ”

"You're a bit of a researcher." Wang Yao moved the black box slightly, and the central tip suddenly emitted a green light, and the light instantly simulated the world outside the pipe.

"Wang Yao, why are you inside?" Jiang Yilang was the first to see the picture, and he was the first to roar.
