Looking at Roland's fanatical attitude, he seemed to be looking forward to staying on this road for the rest of his life. It seemed that as long as he was with Lucy before he died, he looked up at the clouds in the sky and left with him, he was as happy as he was.

Lin Feng seemed to be moved by Roland's behavior, but when he thought that there were still people with Blue Blood, it was really not enough to have their care, so he decided to bring Roland with him.

To this end, the expedition team had to add a doctor's configuration again.

Olivia also followed the team.

Her character is very simple, she takes care of Roland and Lucy along the way, and then finally stays at the front base at an altitude of 5,000, and waits for everyone to go down the mountain before returning to Willis Village together.

"No, something is wrong in this place."

Roland, who was standing next to Lin Feng, grabbed the compass and had a crazy look flashing in his eyes.

"What's wrong?" Lucy asked weakly. After four days of trekking, she was really exhausted. If she hadn't been supported and carried by two blue blood men, she would have been unable to hold on.

Olivia has never been a curious person, and now she is the same. She just carries her own medical box and tries to keep her standing posture.

Andrew was by her side and set up a tent for her.

Hearing Roland's words, she didn't even look over there, but just waited quietly for the tent to be set up, then fell down and rested.

"Compass...the compass has failed!" Roland shouted as if he tried his best, but his voice sounded so weak.

"Andrew, open my bag and it contains plasma."

Lin Feng looked very good in his mental state. He told Olivia, "Doctor, please inject plasma suitable for blood type to everyone."

Then he turned around and comforted Roland and said, "It's okay, we still have satellite positioning, I have a way to determine the location here."

But Roland kept shook his head and said, "No, I think this is very strange, Lucy, remember the map the doctor gave you before leaving? Take it out quickly."

When Roland said this, Andrew was opening Lin Feng's backpack, the only umbrella bag that had never been opened along the way, and took out an aluminum foil box from it and handed it to Olivia. It contained plasma.

This is a common practice in dealing with altitude sickness.

In the front line base, mountaineers are injected with plasma of the corresponding blood type. The plasma is rich in hemoglobin. The increase in protein content in the blood of mountaineers can greatly alleviate the altitude sickness of the team members.

However, the lifespan of red blood cells is very short, only about ten days. After the climbers complete the climb, as the event progresses, the excess red blood cells in their blood will gradually die naturally.

If they slowly fall to the flat ground, they will not experience any oxygen on their mouths.

At this time, Lin Feng took out the micro equipment, Weiss was busy setting up a tent for Lucy, and two blue-blooded men stood on a huge rock and were alert.

After hearing Roland's words, Lucy began to slimly flip the backpack at her feet.

"The compass fails, this is very common." Weiss kept moving his hands, and while setting up a tent, he interrupted, "There may be a large iron ore nearby, so it is normal for the compass to fail."

No one paid attention to Weis's words. Lin Feng was busy debugging the micro equipment at this time. Olivia opened the aluminum foil box and began to select suitable plasma bags.

When he saw plasma bags of various blood types, Olivia couldn't help but glance at Lin Feng and said, "You are really well prepared."

After Lucy spent a long time, she took out a paper tube and handed it to Roland, Olivia pulled Lucy's arm and began to inject her with plasma.

The paper tube opened and an old map was displayed in front of people.

On this map of sheepskin, some places look old in color, while some parts look fresh, revealing traces of repair.

Weis quickly completed the tent building work. He leaned into Lin Feng's ear and muttered in a low voice, "I've heard of a treasure map for a long time, let me see what it looks like."

The way the treasure map is drawn is like a freehand painting.

There is no scale or latitude and longitude sign above, but a tree and a forest are spent in some places, and a river is represented by winding curves.

Even the Andes, the longest mountain range in the world, is replaced by a series of triangle symbols.

In the middle of the map, there is a person's avatar. The avatar is very small, but it can be seen that his finger is pointing at the distant mountains. The image of the person is exactly the same as that Werner found in the desert.

Near the portrait, there is a series of directional signs, and the ink marks look very new, obviously Werner's handwriting.

Along the direction pointed by the portrait, there is a very short straight line, marked with several stone pillars or just simple square patterns.

These patterns located on straight lines have a string of very new markings nearby.

It says: 'discovered', 'suspected existence', 'to be investigated' and so on.

At the end of the branch line, there is a pattern of back-shaped characters. According to the custom of drawing on the treasure map, this pattern generally represents a city and a city with two walls.

"Location, what is the location here?" Roland urged nervously.

Lin Feng reported a string of numbers, which immediately caused Roland to exclaim, and he said, "Lucy! We are at the end of the branch line, and this is the destination of the colossus in the desert!"

"Destination? On a mountain with an altitude of 5,000 meters?" Lin Feng looked astonished and said, "What are you doing to build such a city? Is it fun?"

“Machu Picchu was also built at such an altitude.” Roland retorted “No one knew the purpose of Machu Picchu, just as we did not know the purpose of building the city under our feet!”

"Are you sure there is a city under our feet?" Lin Feng asked.

"I can't be sure." Roland thought for a moment and said, "But the compass has failed here, which means there is a place with a high iron content under our feet.

The end of the map is marked with a city called "Iron City". According to legend, it is all cast of steel, and the city walls and houses in the city are cast of pure iron. It is said that this city is a place where mortals communicate with gods."

Lin Feng glanced at Roland and said nothing.

Roland smiled awkwardly and said, "This is what the doctor told me before leaving."
