Topology, also known as phase analysis at the earliest, was a particularly important part of Leibniz's many brilliant achievements during his lifetime, and as a branch of modern mathematics, topology is still an extremely important discipline in the field of modern mathematics. Pen, fun, pavilion www. biquge。 info

Topology mainly studies the invariant nature of various "spaces" under continuous changes, and if you want to explain all of them, you may have to write a long paper, if you don't directly have the wisdom inheritance of topology, with Tang Li's own qualifications, it is not easy to have a certain degree of understanding of topology in just one week.

If you have to explain topology in the simplest way, you can think of topology as a kind of study of plasticine, by flattening, elongating, and rounding a ball of plasticine, the length, straightness, and plane area of the plasticine itself will change, but its essence is still a mass of plasticine, not torn and separated, and it has not merged with another mass of plasticine.

Therefore, in the field of topology, size and distance are not within its reference range, and the process of changing the shape of plasticine is called topological transformation.

Tang Li, who has the ability of topology, can use topological transformations to fold the continuous space, shortening the distance between the No. 3 arrow in his hand and the target object to the limit.

Xiyue, who was temporarily unable to use gravitational force, was not idle at this time, in addition to using a reflecting telescope to provide Tang Li with an accurate field of vision, Xiyue still needed to accurately adjust the force of inertia to prepare for the upcoming impact when the law of inertia was greatly limited.

"Tang Li, if the two of us die here together......"

"Don't say anything so unlucky, and with my calculus and topology skills, we'll make it. As if echoing Tang Li's words, the "?∫?" shining in Tang Li's eyes. As if it had come to life, the symbol began to writhe continuously.

"Since you're so confident...... Xiyue said as she adjusted her posture and fell in the direction the buffer net was scheduled to unfold.

The No. 3 arrow in Tang Li's hand hit the target the moment he shot through the power of topological transformation. Through the dense foliage, Xi Yue, who used the reflecting telescope, could clearly see that the mesh used to cushion the two of them was smoothly unfolding on the tree.

"3, 2, 1, activate the exoskeleton armor, ready to deal with the impact. "At the moment when she was about to collide with the buffer net, Xi Yue activated some kind of device on her body through the movement of her eyeballs in the visor, causing some of the lines engraved on the suit to shine.

In fact, I wanted to tell Fauber at the time that this design has no other purpose than wasting the energy of the exoskeleton armor.

Although Xiyue thinks so, in the face of the current situation, he has nothing more to complain about.

The soft exoskeleton armor produced by acquiring the latest exoskeleton armor technology and Tang Li's own industrial strength immediately provided powerful kinetic energy for Xiyue and Tang Li's bodies at the moment of starting the energy, and at the same time, through the posture correction function of the exoskeleton armor, the landing posture of the two was also changed through the personalized preset actions stored in the exoskeleton armor.

There are many instances in the world of surviving from falling from a high altitude without a parachute, but absolutely none of them can have the abilities and equipment in Tang Li and Xi Yue's hands while falling, relying on these weights, Tang Li and Xi Yue have increased their probability of surviving the fall to an extremely high point, and successfully hit the cushion net made of elastic material, reducing most of the impact force.

"It hurts, it hurts...... even with the protection of cushion mesh and soft exoskeleton armor, the damage of falling from a high altitude cannot be completely avoided, and it should be said that everything is already good to be spared from such an accident.

Like Tang Li, Xi Yue, who fell from a high altitude, could also feel the body's complaints about herself, but Xi Yue didn't pay attention to the physical pain for the first time, "Turn off the power of the exoskeleton armor first, this thing, although it is very convenient to use, but in terms of energy consumption, it has always been a big problem, and the exoskeleton armor that can only move at full strength for three minutes, is it a defective product made on a certain nebula codenamed M78?"

"Nonsense, this is a product that has poured into the crystallization of our technology, although it ...... Although there are indeed some small problems in the endurance of the product, isn't it also supplemented by a solar charging device?" After hearing Xiyue's bad evaluation of the exoskeleton armor, Tang Li immediately jumped up from the buffer net and argued for his own product.

"Solar? I remember that it seemed like it took 2 hours of continuous sunlight to last 1 minute...... Speaking of this, Xi Yue sighed, looking very regretful, and continued: "Although the technology of soft exoskeleton armor has become more and more mature, there are still big problems in terms of power source. ”

The soft exoskeleton armor that Tang Li and Xiyue were wearing at this time, although in appearance, was not much different from ordinary slim clothing, but in essence, this "clothing" was actually similar to Iron Man's enhanced exoskeleton armor in science fiction movies.

Although it does not have the powerful energy and developed artificial intelligence of the Iron Man suit, Xiyue and Tang Li's suit also has a motion learning function, which can detect the speed and angle of the user's limbs and body through motion sensors, acceleration sensors and gyroscopes, record exercise habits, and cross-compare with the actions stored in the database to select the most suitable movements for the user.

It was with this ability that Xiyue and Tang Li were able to adjust the best posture to touch the net in the fall just now, slowing down most of the impact.

"So, what now? We should have reached the island that Satan spoke of. Tang Li, who jumped from the buffer net, looked at the tall trees around him that almost looked identical, and looked a little overwhelmed.

"If you're talking about the secret island of the Science Society in the South Pacific, I think we're already there. Xiyue said as she pulled out a white piece of letter from the pocket of her jacket.

On this letterhead, which had no handwriting, strange words began to gradually appear, which did not belong to either of Tang Li and Xiyue's cognition, but surprisingly, they were able to clearly understand what these words meant.

"The 111th participant of this batch of evolutionary training, welcome to this competition of natural selection organized by the Science Society......"
