Before these things happened, Lin Feng didn't know that there were so many things going on in the underground world. No matter how you think about it, the plots in the above-ground world would have nothing to do with the underground world. , all of this had nothing to do with the underground world at first.

But now, Lin Feng knows that the source of all this is the underground world. The greed and evil thoughts of human beings thousands of years ago made the outer gods loathe human beings, which eventually led to the extinction of human beings.

The end of endless time is the era of the rule of the Outer Gods, but the Outer Gods do not seem to exist forever, otherwise the current space will not only have humans and a single Naia Outer God.

The era of the Outer God's rule ended very suddenly, as if suddenly, the Outer God was attacked by natural enemies, countless Outer Gods disappeared, and the remaining Outer Gods fell into the cracks in space and began to sleep.

The Outer Gods, who are silent in the mezzanine space, float among the various spaces. When some powerful energy attracts them, the Outer Gods will return to the real space from the cracks, and wake up from deep sleep again. The era of the Outer Gods It will come.

The Agura that people in the underground world believe in seems to be a myth in Lin Feng's eyes. Now the source of the red light in the underground world is said to be Agula's heart, but who can regard the heart as the source of energy, and in a thousand years It can also continuously emit energy fluctuations and rays of light.

The only thought is that Agula is actually one of the ancient Outer Gods. In order to fight against the enemy thousands of years ago, Agura fell into a deep sleep when his energy was exhausted.

As for Agula's heart, whether it is his selfless dedication or human beings can take it, the result is not important, and the reason is not important, everything now is in the past, whether the outer gods can wake up, this is an affirmative answer, and Agula Whether it will be resurrected is also certain. If the heart or part of the Outer God is preserved, there will be a chance to resurrect and wake up again.

In fact, not only the heart of the Outer God Agula remains, the powerful Outer God Agura still has endless blood left on the other side of the underground world, but these blood cannot be contaminated by humans, it is the place where humans end, is The shore that human beings can never reach.

Agula's blood was left on the other side of the underground world. Surrounded by layers of rocks, the ocean formed by this blood was called the blood pool, which was also the terrifying world called hell.

The blood pool is a place of punishment in the huge legendary hell. In the legend, those who are dishonest and crooked will be sent to the blood pool hell after death. Thrown into pools of blood to suffer.

The blood pool in the last days is a gathering place of energy and poisonous gas. The energy of the blood pool and the energy of Agula's heart sense each other. Although the blood pool is sealed and sealed by layers of rocks, the mutual induction between the energies and the energy that belong to one body The attraction is unstoppable.

Gravity refers to the tendency of objects with mass to accelerate and approach, which originates from the bending of space-time by the object's own mass, rather than from the mutual pull between gravitational fields. Therefore, gravity is not the force we usually understand, but formed by the curvature of space-time.

The attractive force between any two objects or particles relative to the product of their masses. The most common force in nature. Referred to as gravity, sometimes called gravity. In particle physics, it is called the gravitational interaction and the strong force, weak force, and electromagnetic force are collectively called the four basic interactions. The gravitational force is the weakest one. The universal gravitational force between two protons is only 11035 of the electromagnetic force between them, and the gravitational force of the earth on the proton is only 11010 of its electromagnetic force in a weak electric field of 1000 volts. Therefore, the effect of gravitation is not considered when studying the interaction between particles or the movement of particles in electron microscopes and accelerators. The gravitational force between general objects is also very small. For example, when two iron balls with a diameter of 1 meter are close together, the gravitational force is only 1.14x103 Newton, which is equivalent to the weight of a small drop of water of 0.03 grams. But the quality of the earth is very large, and these two iron balls are respectively subjected to the gravitational force of the earth of 4x104 Newton. Therefore, when studying the motion of an object in the gravitational field of the earth, the gravitational force of other objects around it is usually not considered. Celestial bodies such as the sun and the earth have very large masses, and the product is even greater, and the huge gravitational force can make the behemoth revolve around the sun.

Gravity becomes the only force that governs the movement of celestial bodies, but the cause of this gravitational force is not the pull between celestial bodies, but the distortion of the surrounding space-time by celestial bodies. The formation of stars does not disperse at high temperature but gradually shrinks, and finally collapses into white dwarfs, neutron stars, and black holes. This is caused by the distortion of space-time caused by its huge mass, and the extrusion of space-time, rather than from its own gravity. Therefore, gravity is also an important factor to promote the evolution of celestial bodies. The greater the mass, the greater the distortion of space-time and the greater the gravitational pull.

Gravity is due to the curvature of space-time. As we all know, the shortest line segment between two points is an axiom in plane geometry, and this line segment is the geodesic. However, in the curved 4-dimensional space-time, the geodesic is also curved. Therefore, under the gravitational force, the planet approaches the sun along the geodesic line. Due to the coincidence of mass and the inertia of the planet, it revolves around the sun in an elliptical orbit again and again. When the mass is not a coincidence, there will be a gravitational springboard phenomenon, or crash into the sun. Among them, the main cause of the celestial system is not gravity, but the space-time distortion caused by mass.

In the last days, the gravitational force between the underground world, the blood pool and Agula's heart is destroying the foundation of the underground world. To be continued.
