Chapter 673

Everyone on earth knows that the earth is round!

The simplest common sense is that the earth is a standard sphere on the globe!

But we modern people realize that the earth is an ellipsoid. In fact, because of the constant rotation of the earth and the great differences in the earth's topography, the centrifugal force on each place is different. For example, the centrifugal force on the equator is far greater than that on the two poles.

As a result, the earth gradually formed an ellipsoid with slightly bulging equator, protruding North Pole and slightly concave South Pole.

However, the newly discovered earth is not a standard ellipsoid. In fact, it looks more like the pear we often eat, so now the earth is also called "pear shape".

In ancient China, there is a saying that the sky is round and the place is round!

When Qin Zhan was born, of course, he always believed that the sky was round and the place was beautiful.

However, this does not affect old man Qin Zhan's knowledge that the earth is round, because he has lived until now. He has never interrupted modern information.

Old man Qin Zhan said this to himself, not because he saw that the earth is round, but because this barrier has radian, and the radian of the barrier is synchronized with the radian of the earth!

In other words, this barrier may cover the whole earth!

This is the reason why old man Qin Zhan would say this!

Qin Zhan didn't give up. He turned back to the origin as fast as he could. Then he stretched out his right hand to feel the barrier and flew in the opposite direction.

This time, Qin Zhan's flying speed is extremely fast, faster than the speed of the car to 100 kilometers!

Old man Qin Zhan stopped again, turned to look back, and felt the origin of his breath. That position and his current position, in terms of the barrier he felt, were still radian.

Old man Qin Zhan returned to the origin again and changed his direction!

As like as two peas, I tried it all over again, and I even tried to do it in eight directions.

This barrier, no matter from which direction to feel, is with radian!

In other words, this barrier really envelops the whole earth!

"What is that?" Qin Zhan was a little absent-minded and said to himself, "cage? The cage of heaven and earth

Old man Qin Zhan reaches out his hand again to feel the barrier with his own genuine Qi.

However, what old man Qin Zhan felt this time is no longer whether the barrier has radian, but what the barrier is composed of!

Old man Qin Zhan is an expert in the robbery period. He can be 100% sure that this is a barrier!

It's not that old man Qin Zhan has never met barriers. However, the barriers he knows are all generated by Qi. Even if he can't break the Qi barrier, he can clearly feel that the barrier is generated by Qi!

This barrier is not the generation of Qi that old man Qin Zhan is familiar with!

Qin Zhan old man after careful feeling, involuntarily frowned!

Because this barrier is almost unbreakable after he feels it carefully!

There are many kinds of genuine Qi barriers, which are generally just used as a barrier. The biggest use is to trap the enemy! In addition, there are some other types of barriers, such as the mountain protection array of Qingyang temple, which is actually a kind of natural gas barrier, but the mountain protection array of Qingyang temple also plays a role in blocking vision, making people unable to see the Qingyang temple in the mountain protection array.

In addition, there are barriers that block sound, but not vision. People inside or outside the barrier can see each other, but their voices are blocked.

Then there is the barrier of unilateral barrier. The people inside the barrier can't see the people outside the barrier, can't hear the voice of the people outside the barrier, or the people outside the barrier can't see the people inside the barrier, can't hear the voice of the people inside the barrier.

However, no matter what kind of barrier, it can be broken.

The simplest way is violence. Violence is always the simplest way to solve problems without brain, that is, to attack the barrier.

Since the barrier is generated by genuine Qi, if the genuine Qi that generates the barrier is consumed, it will naturally break the barrier.

No matter whether the barrier is counterattack or not, as long as the barrier is attacked with genuine Qi, the barrier generated by genuine Qi will be consumed, so as to achieve the purpose of breaking the barrier.

However, generally speaking, such cracking is only suitable for people outside the barrier, but not for people inside the barrier.

Because since the other party will trap people in the barrier, it will be 100% sure that the trapped people can not be solved by violence in the barrier.

Otherwise, it would be meaningless to trap people with barriers.

The arrangement of the barrier is not troublesome. It only needs to release the Qi in the body and use the Qi around.

Old man Qin Zhan, as an expert in the robbery period, can naturally set up barriers. Moreover, in terms of the current situation in the cultivation world, no one can trap him with the Qi barrier, unless it is the barrier generated by the array.

In addition to the barrier generated by the array, there is only one possibility that the cultivation level is higher than the cultivation level.

In fact, old man Qin Zhan was in the barrier at this time. To be exact, all the people on the earth were in the barrier.

Qin Zhan made this judgment not because he was in the barrier, but because he felt the existence of Qi from the barrier!

This is the reason why old man Qin Zhan concluded that this barrier could not be broken by violence!

Old man Qin Zhan didn't feel Qi from the barrier before, because he didn't feel it carefully. It can be felt that the barrier is really generated by Qi.

However, there is a huge difference between the Qi that generates this barrier and the Qi that they set up the barrier!

The difference is that the barrier, concentration, or density, which generates the true Qi is too high!

If the real Qi concentration or density is calculated by quantity, and the real Qi concentration or density that old man Qin Zhan can feel around him is one, then the real Qi, concentration or density that generates this barrier is a thousand times, ten thousand times or even more of the real Qi that they feel!

"Soaring? How does this go up? " Old man Qin Zhan took back his hand, stood in front of the barrier and said in dismay: "is my idea always wrong? Fairyland, where is it? "

Old man Qin Zhan took back his eyes, no longer have any hesitation, control the flying sword, fly back!

At this time, Qin Zhan had only four words in his head --- ancient books and documents!

The speed of old man Qin Zhan's return is much faster than the speed of the imperial sword flying straight into the night sky, so that the body protecting Qi rubs against the surrounding air and emits light, just like a meteor, with a long tail!
