Lin Yifan took a fancy to these forces, they had a deep hatred with the hegemonic forces, and Lin Yifan also hated those hegemonic forces as much as they did.

Lin Yifan wants to use the technology he has mastered to support these forces, and then unite together to establish a stable rear in the Dapeng River system.

At present, most of the forces in the river system are scattered, not to mention that they are not united, and even if they are united, it is difficult to resist those hegemonic forces.

If Lin Yifan doesn't support a group of forces, he will have to face those hegemonic forces alone. Even if he has god-level technology, dealing with several overlord forces at the same time will make his pressure multiply.

Before leaving, Lin Yifan's mother told him that he must find all the crystal stones so that he can find the Star of Hope.

The strength of those hegemonic forces is very strong, and only the stars of hope can fight against it. The Star of Hope is a mystery to Lin Yifan, what kind of existence is it.

"Good! Even if the matter on his side is very important, but now that the signal of the crystal stone is gone, how can we find it? Li Na asked.

"The only way at the moment is to search for spatial energy fluctuations!" Tice said.

"The strength of this spatial energy is so small, it's not a matter to find it like this, is there a better way?" Shangguan Yuyan asked.

"If my guess is correct, the race guarding the crystal stone should have some kind of device that masks the energy fluctuations!" Tice said.

"Then according to you, we have no hope at all!" Li Na said.

"It's not nothing, it's just harder! We need to build some more accurate sensors first, and then set up a monitoring network all over the planet, and as soon as they activate the Space Stone again, we can find out! Tice explained.

"So, if they don't enable it, we won't be able to scan?" Li Na asked.

"Yes! That's where I'm talking about the hard part. Tice said.

"Let's make the sensors first, and then figure out how to get them activated!" Shangguan Yuyan said.

"Swift is right, let's take one step at a time, and we'll always find clues!" Princess Ziyang said.

Tees pilots the Ice Phoenix and lands on a mineral satellite. A large number of engineering robots are then deployed to begin collecting the required minerals.

The number of new sensors that needed to be built this time was high, mainly because the planet was so large.

Fortunately, the Ice Phoenix battleship has enough engineering robots on board, and collecting minerals is not a problem, just wait patiently.

The acquisition took two days, and the first step required the manufacture of a sophisticated measuring instrument. Once the instrument is manufactured, it needs to be tested.

After passing the test, it is necessary to build a small aircraft that can be installed on it. To cover all of this planet, it would take at least a million.

From mining, to testing, to building small aircraft, and finally installing the instruments, it took a week to complete.

Because there are so many of them, it is impossible to put all of these flying machines into the Ice Phoenix battleship. So when it came time to build the vehicle, Tice overhauled the propulsion system so that it could fly directly from the Mineral Satellite.

At this time, all the aircraft have arrived at the intended location. Under Ties's control, all instruments were started at the same time, and now it's just a matter of waiting patiently for the results of the scan.

The scan lasted a day and a night, but nothing unusual was found. Shangguan Yuyan and the others were all very worried about whether that race had left this place with crystal stones.

The Scouting Eye searched every part of the planet, but found not a single intelligent life. Li Na wondered if these people were hiding underground, and finally everyone discussed and prepared to go to the planet to find it in person.

The Ice Phoenix battleship landed slowly, and Shangguan Yuyan, Li Na, and Yinyue got off the spaceship.

Princess Ziyang and the two beautiful guards stayed on the ship, responsible for detecting movements in space.

"Contact Wang Ying and tell her that the Swifts are ready to enter the underground palace, and let her be ready to support at any time!" Princess Ziyang said.

"Yes, princess!"

The beautiful escort immediately contacted Wang Ying and told her about the situation here.

When she came, Wang Ying was not with Shangguan Yuyan, and Lin Yifan needed her to deal with another matter first, assassinating the leaders of those evil forces.

At this moment, Wang Ying has completed the task. When she received the message from Princess Ziyang, she immediately led the shadow troops to rush here.

The three of them came to a ruin, and looked at the dilapidated appearance of the ruin, which was at least 5,000 years old.

Shangguan Yuyan activated the perspective scan of the battle armor and found the entrance to the underground palace. For the sake of safety, they did not go down directly, but put a group of miniature reconnaissance eyes to go to the reconnaissance first.

Soon the miniature scout eye sent back the video of the palace, and the outside of the palace was in ruins, but the inside of the palace was very intact.

From this point, it can be seen that the palace on the surface collapsed because of the passage of time, and there was no outsider to destroy it.

The three of them turned on the battle form of the armor, and then entered the palace. The palace is very large, and you can feel the air surging inside.

The three of them walked along the avenue of the palace all the way to the interior. Twenty minutes later, they groped their way to the main hall. Looking at the decoration in the main hall, it should be the place where the ancient civilization went to court.

Through perspective scanning, the Swifts discover a passage into the main hall that leads to the underground. They made their way to the entrance of the passage and found that the gate at the entrance of the passage was intact.

Swift scans the gate, which is not made of stone, but a special metal. Within the walls on either side of the gate, energy lines were also scanned.

This metal door has an anti-theft code, without which it is difficult for outsiders to enter. However, this was difficult for Shangguan Yuyan and a few people, and Shangguan Yuyan directly used the intelligent system of the battle armor to decipher it.

In just a few seconds, the heavy door was opened. Before Shangguan Yuyan and Li Na could make a move, Yinyue stood in front of them.

"Let me go in first!" Saying that, Silver Moon was the first to rush into the gate.

Shangguan Yuyan and Li Na glanced at each other, they knew that this was Lin Yifan's explanation, and they didn't want them to have an accident.

After Yinyue entered, she looked around, and felt that there was no danger, so she called Shangguan Yuyan and the others in.

Li Na walked up to Yinyue and said with a smile: "Thank you, Yinyue!" ”

"You're welcome, this is my accusation!" Silver Moon said very seriously.

"We are friends and comrades-in-arms, and your life is equally important!" Shangguan Yuyan looked at Yinyue and said.

Hearing Shangguan Yuyan's words, Yinyue felt warm in her heart. It was the first time she felt cared for, and she was so happy that a smile appeared on her face.
