Chapter 638

New York City, near the suburbs. This is an abandoned industrial area, covering an area of more than ten square kilometers. In the past, it was a large chemical plant, but because it was close to the urban area, the plant was forcibly relocated due to pollution. A white car stopped in front of a house in the south of the industrial zone. From the appearance, the house has been uninhabited for a long time, and the cobwebs on the iron door are dense, as if recording the passage of years“ This is it? " Dragon five looked at the broken house in front of him, and an accident flashed in his eyes. Nikola Tesla's name, even her unfamiliar dragon group member, had heard of it. It is reasonable to say that Nikola Tesla's research room should not be like this“ That should be right. " Su Mo was held on his right arm by the dragon four times. Although the blood in the wound had stopped, the whole left arm and right leg had lost their strength. Not only that, he had to endure severe pain all the time. At first, in the imperial library, Su Mo found a handwritten note signed by Nikola Tesla. At first, he thought it was a prank, but he didn't know how amazing the contents of the notebook were until he finished reading it. Therefore, after learning that she was going to be an exchange student in Gamel, sumo began to plan all this. Dark blue crystal and Nikola Tesla's research room... These are all in sumo's plan! There is only one ordinary iron door in the house. In addition, there is no window. What's more strange is that there is no lock on the iron door. No lock on the door? That's strange! How? Dragon five and dragon three looked at each other, and they had a very tacit understanding. At the same time, they raised their legs and kicked the iron door“ Bang - "the iron gate didn't move, but dragon five and dragon three retreated several steps because of the anti earthquake force“ Wait a minute. " Su Mo looked at their slightly white faces and smiled bitterly. He forgot to remind them that the iron door in front of them was made of five kinds of alloys. Let alone kick it with his feet, even the rocket launcher could not explode... Although the appearance of the house looked dilapidated, in fact, the value of the whole house was far beyond ordinary people's imagination! Because the house in front of us, even the walls, are made of metal, which can be said to be the only property of Nikola Tesla“ So hard? " Long San felt a little humiliated. As a member of the dragon group, he couldn't even kick open a door. He felt that he couldn't pass on his face. He didn't believe it. He made full efforts to kick the iron door again“ Bang - "the iron gate is still motionless. The only difference is that the sound is louder than before. Long San's face turned white and stood still. Su Mo hurriedly explained, "this door is made of alloy. It can't be opened with brute force." Long San: "..." why didn't you say it earlier? If he had known this, he wouldn't have kicked foolishly! Shame! What a shame“ Poop, "Long Wu chuckled and said," I think something's wrong. The ordinary iron gate can't bear the power of my third brother and me. " Long San: "..." this made him even more embarrassed! Even dragon five felt something wrong. As a result, he kicked again... "Cough -" in order to avoid embarrassment, dragon three chose to turn off the topic and asked aloud, "Su Mo, how can this door be opened?"“ Knock nine times in the upper left corner and three times in the lower right corner. " Su Mo recalled the way to open the iron door recorded in his notebook. At the beginning, when he saw the way to open the door, he was almost laughed to death. For this way of opening the door, it is most appropriate to evaluate it in two words - wonderful! Hearing the speech, Long Wu went to the iron gate and knocked nine times in the upper left corner and then three times in the lower right corner according to Su Mo's method“ Click click - "a sound of gear rotation sounded, and the iron door rose slowly“ Small four, small five, you two accompany Su Mo in. " Long er suddenly said, "I'm on guard outside. If there's a situation, I'll give you a friendly hint: today's reward amount is less than 30 yuan. Is there a big hand? If not, there will be no reward tomorrow!
