Before I knew it, another two months had passed, and with the help of Tice, fifty more underground palaces had been excavated.

At present, some of the people of Mousse are installing living facilities in the underground base, and some people are installing all kinds of advanced equipment.

In the past two months, Lin Yifan, Tis and Xingsheng have studied green crystal stones together. With the help of the Green Guard, the technology of parsing crystals is much faster.

The green crystal stone contains a lot of high-end medical technology, which can not only treat humans, but also treat aliens and some special lifeforms.

However, Lin Yifan is most interested in intelligent medical robots, which have a very high intelligence coefficient, far exceeding those made by Tis before.

One of the most special medical robots is the Guardian. The Guardian is different from a normal medical robot in that it is mainly used by the intelligent combat robot in the Blue Crystal.

The energy core of this medical robot is very large, and it is responsible for repairing the injured body of the combat robot, while also providing medical treatment to the biological warrior.

"Brother! This medical robot is good, and if you take it with you in battle, you can greatly reduce casualties. ”

Lin Nan said.

"Hmmm! This medical robot is good, we can consider manufacturing one to test the effect, if we can achieve the desired effect, we can manufacture a large number of them! ”

Lin Yifan said.

"Little master! Do you want to build one now? Tice asked.

"I'm afraid not now, we still lack a material that is not yet available on this planet."

The Prosperity interrupted.

"Oh, what material?" Lin Yifan asked with some curiosity.

"Little master! It is a rare mineral, and it is an important material for the manufacture of energy converters. ”

The Prosperity explained.

"It's okay, since we don't have it here, let's go to other planets, I think this material can be found on so many planets."

Lin Yifan said.

"This mineral is very rare, and it's not easy to find it!"

The Prosperity said.

"Ties! Look up the planetary data you searched for to see which planet has this rare mineral. ”

"Yes, little master!"

With that, Tis immediately launched a detailed search, and she called up the data of the thousands of planets. In order to find this rare mineral as soon as possible, she also checked the data of the satellites in the galaxy.

"Little master! Found that there are five planets in the three regions of H-103, A-112, and B-407 that may have this rare mineral on it. ”

Tice said.

"Set the nearest planet as a goal, let's go there first." Lin Yifan said.

"Yes, little master!"

For the sake of safety, Lin Yifan only brought Wang Xiaopang and Li Hu and Li Quan, and the others stayed at the base to defend.

"Brother! You must be careful when you go this time, there may be a base of the Sea Clan in the nearby galaxy. ”

Lin Nan said.

"Don't worry, Lin Nan! Even the Sea Clan elite is no match for the four of us, not to mention that I still have three guards! ”

Lin Yifan patted Lin Nandi on the shoulder and said.

"Well, go and get back!" Lin Nan nodded and said.

"Lin Yifan, wait for me."

"Huh! Brother Darkling, why did you get here? ”

Wang Xiaopang asked with a smile.

"Lin Yifan, take me with you on a mission this time, I'm about to suffocate to death when I stay at home and train every day, let me go out and exercise."

The dark spirit said.

Lin Yifan looked at the dark spirit and said, "I know that training is boring, but the mission we went to perform this time is even more boring, aren't you afraid of loneliness." ”

"I'd rather go out and be lonely than stay at home and train anymore!"

The dark spirit said hurriedly.

"Huh! Alright then, you can come with us! ”

Lin Yifan smiled and said.

Hearing Lin Yifan's agreement, Wang Xiaopang pulled the dark spirit and ran towards the Ice Phoenix battleship, laughing non-stop as he ran.

The dark spirit has been training for more than a year after evolution, perhaps the reason why he wants to take revenge as soon as possible, he has trained quite hard in this more than a year, and his current combat power is also quite terrifying.

Lin Yifan wanted to make the dark spirit strong as soon as possible, and if he brought him out to practice, he would progress faster.

As soon as the Ice Phoenix Battleship entered space, it opened a secret passage, and a few minutes later, the Ice Phoenix Battleship appeared on the nearest planet.

This planet is the smallest in the system, but it is still more than ten times the size of Earth.

There were originally many aborigines on this planet, at least 50 billion before the Sea Tribes came. And under the wanton capture of the Sea Tribe, in less than a thousand years, there are less than two billion humanoids left on this planet.

The planet is devastated, and the once thriving city is in ruins. In order to survive, people can only live in the forest.

Lin Yifan found a forest closest to the survivor base and landed, and then prepared to walk over on foot.

Just as Lin Yifan and the others were about to set off, the dark spirit suddenly shouted: "Lin Yifan! I'm afraid we can't go over like this, at least we have to disguise it. ”

Hearing the dark spirit's words, everyone looked at themselves.

"Huh! The Dark Spirit was right, I forgot about it. ”

Lin Yifan smiled and said.

"Boss! So what do we disguise ourselves into? Wang Xiaopang asked.

"The humanoids on this planet look similar to us, but their costumes are different from ours, we just need to change their costumes!"

Lin Yifan explained.

"Oh, that's easy!"

Saying that, Wang Xiaopang searched the scan data of this planet, and then controlled the style of the battle armor to change into their clothing.

After several people were disguised, they began to walk towards the survivor base. Along the way, they also encountered several waves of hunting humanoids, and they also fought for a prey.

"It seems that we can't just disguise our costumes, we still need weapons to be more like."

Lin Yifan said.

"Captain Lin is right, let's change one according to the weapons in the hands of those hunters."

Saying that, Li Hu controlled the battle armor and began to transform, and after a while, a part of the nano aggregate was separated from his battle armor, and then turned into a weapon similar to the spear used by the earthlings.

"I said boss! They were already close to aerospace technology hundreds of years ago, how can they still hunt with such backward weapons? ”

Wang Xiaopang asked puzzled.

"This can only be known after entering the base, so let's hurry up."

Lin Yifan said.

Several people quickened their pace, and as they entered the next valley, a piercing roar came from ahead.

"Boss, be careful!"

Wang Xiaopang shouted, and then rushed to Lin Yifan's side.

As the harsh sound became louder and louder, a black shadow could be vaguely seen in the grass in front of him, rushing towards Lin Yifan and the others at lightning speed.

When Lin Yifan and the others saw clearly what the black shadow was, they all opened their mouths in shock.

"Sword, saber-toothed tiger!"

Li Hu exclaimed.

Lin Yifan and the others only cared about the saber-toothed tiger, and even forgot to dodge. Seeing Lin Yifan and the others standing in place in a daze, the dark spirit hurriedly rushed forward and pushed a few people away.

"Lin Yifan! What a daze you guys are doing!"

The dark spirit shouted.

Because there was no saber-toothed tiger in the dark spirit's hometown, he wouldn't have the same reaction as Lin Yifan and the others.

was pushed by the dark spirit, and everyone came back to their senses.

"! There are saber-toothed tigers here! Wang Xiaopang said in shock.

"Saber-toothed tiger? You say this beast is a saber-toothed tiger? The Dark Spirit asked.

"Yes! This creature disappeared in our hometown from time immemorial, and we have only seen pictures of it on the Internet, but we didn't expect to see it with our own eyes now! ”

Li Hu explained.

"Oh, I see! No wonder you're standing there in a daze! ”

The Dark Spirit nodded.

While a few people were talking, a group of hunters came running.

"Hey! Where did the toothed beast go? A man with a strong physique looked at Lin Yifan and shouted, seeing that his momentum should be the leader of this group.

"Fang, tooth beast?"

"Yes! We've been chasing it, but it's gone, and don't tell me you didn't see it. ”

The man in the lead said in a strange way.
