With a hook from the gang pet boss, Master Fu fell

Song Yu didn't even have time to pick it up.

After the stone was rolled into the fire, the black charcoal ash on the stone was burned away by the flames in an instant, turning into a crystal clear color, glowing orange under the firelight.

Song Yu looked at Fu Hanyu subconsciously.

Fu Hanyu hooked her shoulders and led her closer to the fire box.

The fire was dazzling and beating actively.

The next moment, the crystal stone suddenly emitted a burst of silver light. The silver light slowly formed a screen-like silver-white curtain in the flames, suspended in the burning firelight.

Song Yu saw that a map began to appear on the curtain. It was completely different from the map of the 'Nuwa' ruins in her mind. However, many of the marked city names, the shapes of mountains, and the directions of lakes and rivers were exactly the same. .

Then, lines of small words appeared, which seemed to be about the algorithm of something. It was very mysterious and profound. She, who was not proficient in numbers and calculations, could not understand it at all.

Fu Hanyu was also staring at the words on it seriously, thinking and calculating. After a moment, his eyes were filled with obvious joy and he said: "This is a derivation and calculation about the location of the city, mountains and lakes in the ruins."

Song Yu:?

Fu Hanyu explained to her: "Based on the map of the last ruins, as long as one location is determined, the locations of other iconic landmarks can be calculated."

Song Yu understood. When he looked at the silver screen in the firelight again, he also showed surprise and said with a smile: "It's okay for him to have done something wrong. I'll call Professor Zhong and the others."

This kind of calculation problem requires the use of scholars like them. There is strength in numbers.

Fu Hanyu nodded. The text on the screen kept changing. He didn't dare to look away from the screen for fear that it would disappear later. He had to use his brain to remember the things on it as soon as possible.

Song Yu quickly called Professor Zhong and Team Leader Liu over. Of course, the people she called were all people she trusted, excluding the three people she suspected and their team.

When Professor Zhong and Leader Liu saw the information on the screen, their eyes lit up excitedly without waiting for Song Yu to explain it to them: "This is the position calculation formula."

Song Yu looked at them and couldn't help but sigh. They are indeed scientific researchers. Their reaction ability and calculation ability are really amazing.

When the Black Queen came over, she saw a room full of people, all calculating and discussing something. Arguing with a blushing face, she walked up to Song Yu, looked up at them, and asked, "What's going on?"

Song Yu explained: "They are calculating the location of Lingquan. My ancestors left me a good thing, a formula for calculating important coordinates in the ruins."

The Black Queen's eyes also lit up: "You mean, we don't need to try our luck, we can use calculations to figure out where the spiritual spring is?"

Please give her this kind of fairy ancestor!

Song Yu nodded with a smile and looked at her: "Yes, once we calculate the location, we will drive the train there directly. You don't have to worry about your injuries."

She was still a little worried that after she went out, even if she had plastic surgery, she would not be able to restore her appearance to her previous appearance.

The Black Queen was not so worried about herself. She looked towards the back of the carriage with a cold look.

Ying Si is a beast with a hard life and good luck.

The calculations and discussions here did not last long. It probably took less than an hour. Based on the previous location of Lingquan, the approximate location of its current location was deduced through calculation formulas.

However, because the current map is slightly different from the map given by Song Beixuan, there are two possible locations of Lingquan.

Everyone was looking at Song Yu at this moment, waiting for her to give her final instructions on where to go. They were the ones who divided the troops into two groups.

Song Yu looked at the map in his hand and marked the original location of Lingquan, which is where they are now, as well as two inferred locations.

These two locations can be said to be polar opposites, one is in the northwest and the other is in the southeast.

After she put down the map, she began to hold her breath and concentrate, counting with her fingers which direction had a higher probability. But after many calculations, she could only figure out which direction was [-]-[-].

She opened her eyes, looked at Professor Zhong, and said, "Go out and ask other people's opinions, whether they are willing to go with me or go in another direction."

These two places were about the same distance from them. According to the speed of the ghost train, it would take two days to reach them.

Ying Si only had two days left. If he made the right choice, he would survive. If he made the wrong choice, he would be dead.

Professor Zhong and the others nodded and went out to find other people for advice.

After a while, he came back again, looked at Song Yu and said: "Miss, we have decided to divide our troops into two groups. Old Liu will take two teams with you, and I will take the remaining people in the other direction.

In this case, if you don't find it there, we can take you there as soon as possible after finding the spiritual spring, and the chance of the winner being rescued will be higher. "

Song Yu nodded and said, "Let's choose a direction!"

After she finished speaking, she threw two folded notes on the table.

Professor Zhong was already used to her various operations. As the leader of another team, he didn't need to ask other people's opinions. He said: "Miss, you go first."

Song Yu was not polite. He took a piece of paper and opened it. It read: Northwest.

Professor Zhong also opened his card, which was Southeast.

The team did not separate here, but let the ghost train take Professor Zhong and others to a city with a teleportation array and drop them off, and then headed northwest at full speed.

The train speed increased to its fastest speed, and it took a day and a half to reach the destination. First it entered the Gobi Desert, and then the endless yellow and orange desert.

The temperature in the desert is very high. Even in the train, you can feel the scorching heat outside.

"Fish." The Black Queen, who was sitting in the passenger seat, suddenly shouted excitedly, pointed to the front and said: "Oasis, there is an oasis ahead."

Song Yu yawned and opened his eyes. He looked out the window and saw the emerald green color on the opposite side, like an emerald gem in the golden desert, which was eye-catching.

In the distance, she saw the shimmering water through the gaps in the green trees.

"That water, could it be the spiritual spring we are looking for?" The Black Queen also saw the water, and murmured while being fascinated by the scenery in front of her.

They saw an oasis.

The other people in the car naturally saw it, and their eyes were shining with excitement and their faces were red. They wished they could get out of the car right away and go explore the oasis.

The ghost train stopped near the oasis, about three kilometers away.
