Roaming the universe, all thanks to your many dark skills!

"Stop, stop." Rosen pressed Mark's helmet and pushed him one meter away, saying, "What next?"

"What then?"

"Brother, what are you doing?" Rosen held his helmet with one hand and said speechlessly, "Sometimes, or most of the time, you always have some complicated exchanges with the Earth, and maybe even discuss some difficult astrophysical engineering issues."

Pointed in the distance, in the direction of the Pathfinder.

Rosen said, "Didn't you say that your communication with the other party is just YES OR NO? This is not as good as the information I convey when I communicate with my crows. What's the point?!"

"By the way." He seemed to think that Mark was not hit hard enough, and added: "You also said that there is a time delay of more than 30 minutes between Mars and Earth. Communication will be extremely slow."

"You're right, I've been thinking about this as well."

Mark said, "I've thought about it. I can make an alphabet, but not our alphabet. 26 plus the problem sign, minus 360 degrees, each angle is 13 degrees, which is too narrow. If the camera turns around, I don't know which area it is pointing to."

"What you should be more worried about is that before you figure it out, the camera might have been spinning in circles and broken down," Rosen continued to complain.

"So I decided to use hexadecimal," Mark said. "I remember a teammate always threw ASCII tables everywhere, so I should be able to find it."

"Then go ahead." Rosen waved his hand and said, "Whether you succeed or not, don't disturb me. I'm going to sleep."

"Rosen, for the sake of our sharing of joys and sorrows..."

"Stop, if you have something to say, just say it. If you have something to say, just fart." Rosen said, "It's no use trying to befriend me."

"I'm hungry, is there anything to eat?" Mark said with his hands clasped together.

"There are leftovers in the kitchen. Go and eat them if you're not afraid of poisoning." Rosen said without paying any more attention to him and went back to his room to continue sleeping.

Solar Day 110.

Mark regrouped and continued to complete the big things he had not yet completed.

Rosen was no longer at home at this time. He was not very interested in contacting the Earth. Anyway, this was not his world, and there was no one he was familiar with. Even if he wanted to contact someone, there was no one he could contact.

Oh, no, maybe Diana too.

Maybe she also exists in this world.

But when I thought about the fact that we are now tens of millions of kilometers apart from each other, all my longing for each other collapsed on the spot.

Rosen felt that his teleportation and delivery were still too low level.

If we could be like the bald old wizard in Marvel, go wherever we want in the universe and travel freely in the past and future, then why would we worry about the distance?

The more he thought about Rosen, the more he felt that he couldn't waste his precious time.

So I continued to improve my skill proficiency and explore Mars in my daily activities.

When Rosen first arrived, he really thought that Mars was a desolate planet with no living creatures.

Even if Mark told him that there was water on Mars, there was a high possibility of life.

But Rosen didn't take it seriously at all.

Until this time when he went out with Mark, sometimes he drove the Mars rover himself, and sometimes he sat in the passenger seat and looked around boredly. When he walked far enough and saw enough, the knowledge about Guigu's secret technique suddenly popped up in his mind.

Although there is no vegetation on Mars, there are mountains.

Although no water can be seen, there are traces of the existence of rivers and lakes.

They are everywhere on the Chris Plain, especially in the Ares Valley adjacent to it, which has the characteristics of being eroded by water.

After understanding the shape of the mountain, the terrain, and finally the direction of the river, Rosen was surprised to find that if he analyzed it with the Guigu secret technique, Mars was definitely not as simple as he had thought before.

Are there really Martians?

Or is there some big stuff hidden?

At this moment, Rosen couldn't help but get excited.

His reason told him that there was most likely nothing on this red, shabby planet and it would be useless to look for it.

However, based on the principle that since he was already here and had nothing to do, Rosen decided to walk around. If he really found something, even if it was just some rare meteorites, his trip to Mars would not be in vain.

Exploring Mars sounds cool, but it's actually really dull and boring.

Although Rosen has teleportation and projection, he can appear anywhere 5-10 kilometers away at any time as long as his sight is within reach.

But if you just go through it in such a cursory way, you are likely to miss many important details.

This made him miss his crow very much.

However, he had secretly tried it before, and in an environment like Mars, the crow would surely die as soon as it came out.

Ghost wolves are slightly better than crows, but if they stay too long they will still die because they cannot withstand the harsh environment.

So Rosen had to leave the task of exploring everywhere to the poisonous vines and clay golems.

With the two of them tirelessly moving underground and walking on the ground respectively, he would share their vision from time to time, so at least he would not miss anything too important.

As for whether the huge clay golem would attract the attention of NASA satellites in the sky, to be honest, Rosen didn't really care.

As long as they don't tell me, they will never know what the clay golem is even if they rack their brains.

Besides, even if I really said it, they might not believe it.

While Rosen was busy with his own exploration, Mark's communications with Earth were also going well.

With the previous method, the communication between the two sides was at least smoother, but the amount of information transmitted was still slightly insufficient, so the engineers on Earth sent Mark a method on how to hack into the Mars rover so that it could communicate with the Pathfinder.

Mark hacked the rover by following the same pattern, and modified the rover's operating system in about 20 places with a small piece of code. Then NASA connected the rover to the Pathfinder's radio frequency, and the two sides could communicate normally.

This step is of great significance. It is equivalent to being able to shout to each other instead of just making blind gestures across a distance of dozens of miles, greatly improving the efficiency of information transmission.

However, Mark did not talk to NASA about this. Instead, he waited outside the container villa for most of the day before he saw Rosen coming back from outside.

"Rosen, I've already contacted NASA." Mark looked at Rosen, a little excited and a little nervous, and said, "But I haven't responded to their greetings yet. I hope to communicate with them when you are here."

To be honest, Rosen was really touched at this moment.

Even a letter from home in March is worth a fortune, not to mention that Mark is so far away from the earth now, he must be eager to know many things.

But he was able to endure until now just to wait for me, which was enough to show that he really regarded Rosen as a very important friend.

"Thank you." Rosen said, "Then talk to them. I'm also curious about what they will say."

Mark nodded, turned on the computer on the rover and began to respond to Vincent's greeting.
