There are already more than a dozen such objects whose shapes can be distinguished by telescopes, and there are a large number of objects further away that can only be seen as point-like objects, totaling hundreds of unknown objects.

Like the "Lord of the Rings", they show no signs of activity or emit any detectable signals. Another thing they have in common is that they are closed four-dimensional entities.

Guan Yifan proposed to General Chu Yan that he would fly a scientific research spacecraft to inspect the "Lord of the Rings" at close range and, if possible, enter its interior.

After a brief discussion by the Human Federation Military Commission, Guan Yifan's proposal was approved, and an expedition team of several hundred people was formed.

This expedition team has three captains. In addition to Guan Yifan, there are also Scientific Officer Zhuo Wen and Dr. West.

Zhuo Wen is the chief scientist of the Human Federation and has relatively rich experience in four-dimensional space navigation. Doctor West insisted on joining him.

Dr. West was approved mainly because he had experience studying trisomic linguistics before setting sail.

The longest voyage that humans have ever conducted in the four-dimensional space was the Human Federation's attack on the water droplet and the pursuit fleet.

At that time, the Human Federation used a space shuttle to pursue the fleet through a four-dimensional approach, and first sent a dozen scouts to conduct investigation work.

Then the large shuttles were divided into three batches and dropped more than 6,000 marines from the fourth dimension into the ships pursuing the fleet. Smaller space shuttles were used to attack the water droplets.

But this time, the exploration of the "Lord of the Rings" took a much longer journey, and the research ship entered the fourth dimension from a warp point between the two spacecraft.

Behind the people who set off on the expedition, the nuclear fusion fireball of the scientific research ship's engine was burning. As the power increased, it changed from dark red to faint blue.

The countless large fireballs in the heavy element fusion reactors of the more than 500 stellar-class battleships and Star Destroyers behind them illuminated this infinite world unfolding side by side.

After gradually entering the depths of space, the sense of high-dimensional space becomes even stronger.

Although Dr. West has entered the fourth dimension twice, he still can't help but admire: "What kind of mind can grasp such a world!"

Drivers use eye-tracking mouse or voice control when driving scientific research vessels, and generally do not use their hands to avoid touching exposed sensitive parts.

At this time, the "Lord of the Rings" was still a faintly visible dot to the naked eye, but he still carefully drove the scientific research ship at a very low speed.

Due to the unmeasurable extra dimension in space, the distance seen visually is completely unreliable. The "Lord of the Rings" may still be far away from one astronomical unit, or it may be close in front of us.

……..

The voyage lasted three hours. The scientific research ship had exceeded the furthest voyage ever made in four-dimensional space, and the "Lord of the Rings" still looked like a point.

But the driver became more cautious and was ready to decelerate and make emergency turns at any time. Guan Yifan beside him became impatient and asked the driver to increase the speed.

At this moment, West exclaimed, the "Lord of the Rings" showed a ring shape, which appeared suddenly, from a point to the size of a coin in an instant, without a gradual increase in size.

"Always remember, we are blind in the fourth dimension." The driver said, slowing down again.

The voyage lasted for more than two hours. If it were in three dimensions, the scientific research ship would have sailed about 200,000 kilometers.

Suddenly, a coin-sized "Lord of the Rings" appeared in front of the sky. The pilot used his eyes to control the scientific research ship to turn urgently, so that the scientific research ship that hit the hoop passed through the ring of the "Lord of the Rings".

From the scientific research ship, it looked like it had passed through a huge arch in space. The scientific research ship then decelerated with all its strength and returned, hovering not far from the center of the "Lord of the Rings" circle.

This is the first time that humans have seen four-dimensional objects at close range. Similar to the sense of high-dimensional space, they feel the grandeur called high-dimensional texture.

The "Lord of the Rings" is fully enclosed and cannot see the inside, but they can feel a huge sense of depth and inclusiveness.

From the perspective of the three-dimensional world, the "Lord of the Rings" we see is not one "Lord of the Rings", but the superposition of countless "Lord of the Rings". This four-dimensional texture is breathtaking and is the real mustard seed.

realm.

The surface of the "Lord of the Rings" seen from this distance is very different from that observed through a telescope from a spacecraft. Its color changes from golden to dark copper.

Everyone on the scientific research ship felt familiar with the old surface, and they thought of the destroyed water droplets.

Everyone then imagined what an amazing sight it would be if this huge four-dimensional ring once had a bright mirror surface.

Then according to the plan, Zhuo Wen sent a greeting using medium frequency radio waves. This is a simple dot matrix diagram, which consists of six rows of different numbers of points forming a prime number sequence: 1, 3, 5, 7, 11, 13

.

They didn't expect to get a response, but the alien's response appeared immediately, so fast that everyone couldn't believe their eyes.

The information window suspended in the cockpit displayed a simple dot matrix diagram, similar to the one they sent, with six rows of dots forming six prime numbers.

But the dot matrix in the picture is much larger, taking over the sequence they sent: 17, 19, 23, 29, 31, 37.

The meaning of the other party is very clear, that is, they have answered their greetings.

In the Human Federation's expedition plan, sending greetings was just a casual attempt, and there was no preparation for further communication after receiving a response.

Just when everyone was at a loss, the communication system of the scientific research ship received the second dot pattern sent by the "Lord of the Rings", which was a sequence of numbers: 1,3,5,7,11,13,1,4,2

,1,,5,9.

Soon they received a large number of dots, and the first six prime numbers were sent as greetings.

As for the next six numbers, Zhuo Wen, West, and the other officers all turned their expectant eyes to Guan Yifan, a scientist.

The cosmologist thought about the series of numbers that kept appearing in the display window for a long time, and finally shook his head in confusion and said: "I can't see the pattern of the last six numbers."

"Then assume there is no pattern." West pointed at the display window and said: "The first six numbers were sent by us, and the most likely meaning is that they represent us."

"The last six numbers have no rules, and different combinations keep appearing, which may represent everything, I mean everything about us."

"It wants to know our relevant information?" Zhuo Wen asked.

"It's more likely that it's a language sample so that 'it' can decipher and learn it before communicating with us further," West guessed.

"Then send it the Rosetta system." Guan Yifan suggested.

"This requires asking the higher-ups for instructions." Zhuo Wen hesitated for a moment and then said.
