The portal is indeed a door, but it is a door with only a frame and no door panels. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The quaint portal has a mysterious color, a total of two meters high, three meters wide, the overall structure is a simple copper color, painted with mysterious lines, wonderful and abnormal.

With a gentle pull, the portal fell to the center of the hall, and then embedded directly into the floor of the hall.

"System, isn't that the way it works?"

Wang Xing always felt a little unreal, and the layout of this portal was too simple.

"The host, the portal is actually a spatial node, through which you can connect to another space. The host can now give it a try, and the connection has been established on the Academy's side. ”

"Okay, I got it. ”

Wang Xing walked into the portal, as if he had passed through a one-and-a-half-high tunnel full of various colors, and a sticky feeling crossed his body. He tried to see everything in the space, but found that his eyes were a little sore.

Suddenly, his eyes lit up, and he had arrived at the gate of the academy.

Looking back, the place where the academy leads to the outside world already has a slightly smaller space door.

Wang Xing nodded, this portal has entry and exit, and it is indeed the same as the connection point of Tianxian Mountain, which can greatly facilitate the travel of students in the future.

Returning to the Magical Guild again, Wang Xing saw that Barnion and Belom were also trying to use portals.

"What's going on, why can't we get through?" Barnion was a little puzzled.

"This is a portal for the exclusive use of our academy, so naturally you can't use it. Wang Xing said lightly, "Now that the Immortal Academy has been connected to the Magic Association, once there is any change here, you can call me as soon as possible." In order to prevent the other party from blocking the mobile phone signal, I will also send students to stay here for a long time. ”

When the two heard this, they were completely relieved.

However, they also know that the Immortal Academy can reach the Magic Association at any time, and in the future, the Magic Association will be completely controlled by the Immortal Academy, and this place will soon become the back garden of the Immortal Academy in the West. Although there was no further action from the Immortal Academy, as time went on, it was basically a sure thing that the Magic Association would transform into an elementary school attached to the Immortal Academy.

The Academy of Sciences of China.

Wang Xing saw Mu Liuli, and now her cultivation has reached the seventh level of the True Yuan, and she has not fallen behind because of scientific research.

"The three hundred and twenty-ninth test failed, and the preparation for the third hundred and thirtieth continued. ”

"Yes, Dr. Mu. ”

Mu Liuli's assistant whispered beside Mu Liuli at this time: "Doctor, someone is looking for you." ”

Mu Liuli looked at the visitor's information and hurriedly left the research room.

In a separate research room, Mu Liuli took out some information: "Dean, after my research, I found that all spirit stones should have the same shape, that is, this hexagonal crystal the size of an egg yolk and showing a blue hexagonal crystal. The energy contained in the spirit stone is also exactly the same, it is equivalent to the energy released by the explosion of one kilogram of TNT. According to speculation, it should be an ordinary object, in which stones are the mainstay, and if it absorbs such a large amount of energy, it will be converted into spirit stones. ”

"Oh, so all the spirit stones in the world are the same, I thought there would be higher-level spirit stones. ”

"The energy contained in the spirit stone, the shape it maintains, and the form that is too small just forms a perfect structure, so theoretically the spirit stone is the same. ”

Wang Xing nodded: "The energy in the spirit stone can be easily absorbed by cultivators, but it is difficult to find spirit stones on the earth, only those small worlds can exist spirit stones, what do you think is because of this?"

"The formation of spirit stones is a process of gathering and storing energy, and the human beings on the earth have developed rapidly and have been taking energy from the earth, and there will be no excess energy to form spirit stones at all. However, in the ancient period of the earth, human beings had less need for energy, and there should be spirit stones. If you think about it this way, in the depths of the sea and some other places where humans have not set foot in the earth, the energy has formed a kind of blockade, and if the spirit stones in it have not dissolved and returned to nature, there should still be some. ”

The earth is so big, it's too normal to have a spirit stone, but if you really look for it, it will be worth the loss.

"Is there a way to detect spirit stones?"

"In principle, any substance has its own specific properties, and it can be detected by relying on these specific properties. However, because most of the spirit stones are hidden in the depths of the earth, and the underground environment is complex, there are many interferences, so there will be deviations in large-scale detection, of course, this is also our technology has not reached. I tried many times, and made a single detector that can detect energy bodies with a large amount of energy at a depth of 30 meters underground, and the spirit stone is within the detection range. ”

"30 meters is too little. ”

"The dean is right, 30 meters is really not much, but if we have 100 of these detectors, then we can detect energy bodies at a depth of 3,000 meters vertically. If there were 10,000 of these detectors, all energy bodies within a radius of ten miles would be completely hidden. The most important thing is not this, based on the scientific and technical data brought back from the alien world, I have developed a small sapper detection robot that excavates resources, which can be perfectly equipped with this detection system. ”

Wang Xing was stunned, and then ecstasy.

"In the alien world, human beings' development of other planets has reached a very powerful level, and the research of robots is also extremely powerful, and even cyborgs similar to humans have appeared. I've dismantled a spaceship, I've learned a lot, and I'm still slowly digesting the technology. Dean, come with me, let's take a look at this detection robot first. ”

Mu Liuli is full of fanaticism about technology, which is unmatched by everyone.

Wang Xing soon saw Mu Liuli's invention, which was thirty centimeters high, six centimeters long and wide, with a silver metal drill bit ten centimeters long at the top, and two eight-centimeter-long humanoid arms that could shrink into the body, while the feet were only six centimeters long, which seemed top-heavy and awkward.

Wang Xing almost couldn't help but laugh, this effect was so funny.

Mu Liuli pressed a dent button on the chest of the detection robot, and actually opened a door from the chest of the detection robot, and looked inside, there was exactly a space the size of an adult's fist.

"If the probe robot finds a spirit stone, it will dig it out and store it here. If it is completely full, it can fit five spirit stones. Mu Liuli said slowly, this can be regarded as her proud work, "The energy used by the detection robot is solar energy, full of energy, and it can shuttle about a thousand meters underground. However, because the current solar technology is not too mature, even if it is all sunny, it will take three days to fully charge. ”

When Wang Xing heard this, he was actually very satisfied.

However, Mu Liuli's surprise was obviously not over yet, she continued: "But I have already thought of a solution, this spirit stone is a natural energy battery. (To be continued.) )
