On the ninth day after leaving the base, Fang Zhe and others left the haze area and entered a relatively clean place. Before entering the Sun Forest, they could turn off the internal circulation system. Of course, everyone who had not breathed fresh air for a long time had to enjoy the free breath outside the haze.

Only such a place lives in it. However, this is not enough. They need to return to the human world and live a normal life.

"We are about to reach the Sun Forest. The Sun Forest is very large, and the experimental area is in the center of the Sun Forest. Therefore, we have to catch a long journey." Lao Laodao.

Entering the green sun forest, they first rushed to Mr. Luo's nest.

Mr. Luo’s nest is on the edge of the Sun Forest. They only spent half a day to arrive at the valley full of snakes and poisonous miasma.

When he came back this time, Luo always planned to take away dozens of small snakes. These small snakes can be used for investigation and destruction, which is of great help to their plans.

After another five days of trek, they came to the area close to the experimental area. If they used the mecha, they could reach the experimental area in just one day. However, they could not drive the mecha to the experimental area.

Hao Fan put all the mechas into the space ring, and everyone took the big snake to rush on the road, and at the same time used the small snake to detect and conduct timely blocking and monitoring.

Their destination is not the experimental area, but the Rat Valley near the experimental area. There are many mice in the Rat Valley, which are an excellent place for invisible mecha testing.

When the rat met a snake, the rat fled immediately, and Fang Zhe and his group did not encounter any obstacles.

The next thing is to wait for the rabbit.

"Grandpa Luo, what if they don't come in the future?" Fang Zhe was a little worried.

"Haha, here, the food and air are endless, so let's wait." Old Luo smiled.

But when he saw the others looking at him with dark lines, he immediately did not dare to joke. He patted his chest, "But don't worry, their stealth mecha will definitely take the final test, and even the last test will take much longer than before. If we snatch the stealth mecha, they may take a long time to discover it."

"Old Luo, do you know what tests the invisible mecha have been conducted?" Hao Fan asked.

"A very important aspect is the impact of the mecha on the environment. On the one hand, it is the problem of heat conduction in the mecha, and on the other hand, it is the problem of receiving external information. These three aspects are problems that invisible mechas must solve. Now, these problems have almost been solved."

Hao Fan's face was full of surprise, "Didn't you say that the invisible mecha can't receive external information?"

"Don't worry, it's not about receiving radio wave information, but about the ability to observe the external environment. If you can't observe the external environment, how should the invisible mecha sneak attack others? Their solution is to speed up the mecha's speed of collecting the external environment and control the exposure as small as possible. Now, the invisible mecha will scan the outside world every ten seconds, and at the same time automatically predict the whereabouts of the target. The scanning speed is very fast, and it only takes a moment."

"Those scanning waves can pass through the two-point five-dimensional crystal stone?" Hao Fan still looked worried.

"No, the two-point five-dimensional crystal must completely cover an item to give the item a transparent characteristic. They need to open a part of the mecha's appearance before scanning. This is the time when they expose their tracks, but this period is very short, and the exposed area is not big, which ordinary people cannot find."

Everyone else nodded, and Fang Zheze asked, "It's really strange. A communication device is not very big. Since they are equipped with scanning devices, why not install communication devices on the invisible mecha?"

Others were also awakened by Fang Zhe's questions. Now, they don't understand how the 2-point five-dimensional crystal can ensure that the heat source of the mecha is not exposed.

"Your question is really good, but it is impossible for us to answer you. You must know that the Mozhe Royal Family has so many top scientific researchers and it took more than ten years to perfect the invisible mecha. Do you think we can solve the problem in just a few words? I can tell you with certainty that the invisible mecha really does not have a communication device. I guess the scanners in the invisible mecha are specially made, which is different from the scanners we have seen."

"Haha!" The others raised their heads and laughed. They also thought that Mr. Luo's words made sense. The issue of invisible mechas was indeed not something they could imagine. If they continued to discuss it, they would be a laughing joke.

Fang Zhe also touched the back of his head awkwardly, because he was too careful.

"Brother Huai, look, Kui Mu 8 stars are right in front of you!" A beautiful mature woman stood in front of the window and looked a little excited.

The handsome young man who was called by the woman had a cold face. He stared at the gray-white Kuimu 8 stars and said lightly, "This planet that is about to be broken actually produces such magical substances. The power of nature is really mysterious."

"Of course the universe is full of endless mysteries, so let's not say much." As he said that, the beautiful woman hugged the boy's arm and rubbed it. "Brother Huai, my father gave you an invisible mecha. At that time, I will lend it to my sister to play."

The boy reached out and pinched the delicate woman's soft hand, "Sister Yan, of course, it's possible, but it's only limited to Kuimu's 8 stars."

Although the woman with a hot figure in front of him was given the position of princess by Emperor Mo, she was the cousin of her half-sister. She had no blood relationship, so the young man certainly would not have any scruples.

Although the status of Princess Jiaoyan is not lower than that of a boy, she is like a little handsome man, so she immediately turned around and gave the handsome boy.

When their spacecraft landed on the experimental base, the Sun Forest just entered the night.

There were people waiting for them in the 8-star Kuimu experimental base. The ground guard captain personally met the visiting royal children, and the reception specifications were very high.

However, the visiting prince was not moved by the banquet, and only ate a little bit of food, and immediately asked the captain of the guard to take him to see the invisible mecha.

In the experimental base, not many people know that the invisible mecha exists. Apart from the researchers, the captain of the guard and the two new members of the royal family, there are only three full-time testers left.

After passing through the layers of gates, they came to a wide basement.

In the wide test square, Prince Huaizhe and Princess Ru Yan each tried to control the invisible mecha, bypassed hundreds of intelligent robots, and completed the test task at an extremely fast speed.

The captain of the guard and three full-time testers patted their hands and still tried hard to applaud the outstanding performance of the prince and the princess.

"The invisible mecha is indeed amazing!" Prince Huaizhe and Princess Ruyan both gave extremely high evaluations of the invisible mecha.

Then, Princess Ruyan said, "I want to drive the invisible mecha to try outside the base!"

"No!" The captain of the guard immediately refused. As a member of the royal family, he knew the princess in front of him. He knew that the other party was extremely noble and was no less than the talented Prince Huaizhe. He must not let him do risky things. "Before delivering the invisible mecha, we must conduct the final test of the invisible mecha. The final test takes a long time. In order not to delay the two of them, we should give it to three full-time testers and let them complete the test as soon as possible!"

Thinking that she had important things to do, Princess Ruyan nodded, "Okay, please complete the final test as soon as possible!"

"Yes!" The three transfer testers saluted before entering the miniature mecha.
Chapter completed!
