When Fang Zheng returned to Tiandao Palace, several days had passed.

“Huh…”

Fang Zheng yawned and felt a little tired. He did not trigger any tasks this time. It can be said that this world is the most free-spirited one that Fang Zheng has ever experienced in the dungeon. To put it in an analogy, he used to play RPGs when he entered the dungeon before. There were main quests and side quests. After completing them, he would get the achievement settlement and get the reward equipment.

But this time Fang Zheng felt like he was playing a sandbox game, he could do whatever he wanted. Of course... apart from making enough food and clothing by himself, he couldn't expect to get any rewards.

But in fact, Fang Zheng did this because he found that he really didn't need anything in the monster world.

Although the technology of humans in that world is relatively advanced, Fang Zheng hacked into the server to analyze their technology, but he found that there was nothing useful in this world. I don't know if it's because of the nature of the monster world itself, but the technology tree of this world is a bit biased, just like the Matrix. If the humans in the Matrix world are biased towards the virtual reality specialization technology tree, then the technology tree of this world is all biased towards Gundam.

From metallurgy to electronics, from energy to informatization, all the highest-level technology points are for the service of mecha hunters. As for other weapon systems, such as firearms, missiles, aircraft, etc., that world is only about 1.5 generations more advanced than the world before Fang Zheng's rebirth.

This level of technology is useless to Fang Zheng. Although that world has micro-nuclear fission technology, Fang Zheng can't use it. His Haiwu Fleet uses Haiwu's gravity reactor in the atmosphere, and uses its own dark matter power engine outside the atmosphere, both of which are much stronger than nuclear fission.

As for the city... with the Protoss technology as a foundation, Fang really doesn't care about this level of technology.

However, in line with the principle that a thief should not leave empty-handed, Fang Zheng secretly packed up a portion of the technology from that world before leaving. Although he could not use it himself, perhaps in the future when there is a shortage of energy or in a world set in the late 20th century or early 21st century, he could use the things in his hands to trade with the forces of that world.

On the contrary, Fang Zheng was greatly disappointed by the Kaiju alien force in the Monster World. This alien force followed a similar biological route as the Zerg, but the technology tree was not as high as that of the Zerg. It was basically like the situation in Civilization where I had a modern army but the other side was still using muskets. Moreover, the group composition of this alien force was very similar to that of the Zerg, and they were extremely fragile. In the eyes of the Zerg, they were not even worth assimilation. So Fang Zheng finally just destroyed this alien force and went home with a wave of fat Zerg.

Although the system also suggested that Fang Zheng could incorporate the Monster World into the Free World, Fang Zheng thought about it and finally chose to give up. The Free World was limited, and the Monster World was meaningless in terms of growth space and strength, so Fang Zheng did not choose the Monster World in the end, but went home to rest.

"Sure enough, it's more comfortable to go home..."

Looking at the peaceful Tiandao Palace in front of him, Fang Zheng also stretched his body leisurely. In the monster world, he basically did nothing but eliminate those alien invaders. After all, Fang Zheng's position was still there. Unless they were like those in the dark world who had no medicine to save them and could only wait to die, otherwise if humans were threatened, he would still help. These alien creatures have been trying to invade the earth for more than a day or two, and Fang Zheng certainly would not be lenient with them. He swept them all away and cleaned them up.

At least in this way, there would be one less alien race spying on the earth. As for whether that world would encounter other troubles in the future, such as a long-necked lizard with three heads, or a fluttering moth, that was none of Fang Zheng's business. After all, he was not the father of the human beings on Earth, and some things still had to be handled by themselves.

"I'm back!"

Fang Zheng pushed open the door and couldn't help but yell. Upon hearing his voice, the kitten and the little fire dragon crawling on the sofa immediately raised their heads and looked towards Fang Zheng. Then, accompanied by the sounds of "meow" and "ya ya", the cat and the dragon immediately pounced towards Fang Zheng.

The kitten jumped up, and then went directly into Fang Zheng's arms. The little fire dragon also lay on Fang Zheng's shoulder, rubbing against Fang Zheng's cheek...

"Well, the little guy is so good..."

After caressing the little kitten in his arms and patting the little fire dragon beside him, Fang Zheng felt that he was already a winner in life. Even if he didn't have a dog, raising a cat or a dragon would also be beneficial to his physical and mental health.

"There's no one here now..."

Fang Zheng was quite calm after seeing the empty hall. This was his mansion, but it also served as a "dormitory". For example, Hecate and Xia Shi were like this. After making breakfast in the morning, they would go to school to teach and study, and would not come back until the afternoon.

Of course, not everyone has left, at least some people are still here.

"Captain? You're back?"

"I'm back, Iona."

Looking at Iona in front of him, Fang Zheng waved his hand and said hello to her. At present, in Tiandao Palace, the ship girls are the most idle. Apart from their fixed daily patrol tasks, they basically spend the rest of their time slacking off. As Fang Zheng's secretary ship, Iona is basically a full-time housekeeper here.

"how are things?"

"Everything is fine, no problem."

"Yeah...is there anything I can do for you?"

"Of course, Captain, I have the paperwork sorted out."

As a secretary ship, Iona was obviously very dedicated and conscientious. When she heard Fang Zheng's question, she nodded.

"Miss Nymph has received news that the thing you asked her to make has been completed. Also, Miss Tilia wants to discuss with you about... 'media' issues."

"oh?"

Hearing this, Fang Zheng's eyes lit up, and he walked into his room with the two little guys. Soon, Fang Zheng saw a flat box on the desk, and inside the box was something like a bracelet, with an instruction manual next to it. Fang Zheng picked up the bracelet and put it on his wrist. Soon, he saw a faint light outside the bracelet. Then Fang Zheng stretched out his hand and clicked it, and then a virtual screen appeared in front of him.

"It looks like Nymph did a good job."

Looking at the screen in front of him, Fang Zheng nodded with satisfaction. He had always wanted Nymph to design a tool to replace smartphones and computers. After all, there was no unified communication tool in the Tiandao Palace, which was very annoying. Most of the little guys from the dark world used mobile phones and the Zerg network, while Hecate and Tilia used the Red World's Freedom Method to communicate remotely, and Nymph used her chain to directly transmit information to Fang Zheng. As for other messages, the little angel would use radar to search and sort them out.

The Sea Mist Fleet, led by Iona, uses the Sea Mist Core Network...

This also makes it difficult to transmit various messages. For example, if Xia Shi or Cui want to pass on Fang Zheng's orders, they need to use their mobile phones. If they need to transmit information to each other, then Nymph needs to find Xia Shi or Iona and let these people use their respective networks to transmit information.

This is obviously a very troublesome and inconvenient task, so Fang Zheng gave Nymph a task before, asking her to find a way to create a portable, multifunctional tool that can combine communication and information processing, so that it can be equipped to everyone in the Tiandao Palace. In this way, it will be much more convenient whether it is transmitting information or commands.

And now it seems that Nymph has obviously completed this task.

From the current perspective, the bracelet in front of him is quite convenient. It can unfold a virtual screen and keyboard of adjustable size in front of Fang Zheng. Its usage is similar to that of a tablet computer. As long as Fang Zheng stretches out his hand and slides and clicks on the screen, he can start the program, and the virtual keyboard can directly and quickly input the information Fang Zheng needs.

Unlike those projected keyboards, Fang Zheng could feel that these virtual keyboards had "quality" when pressed. The feedback was quite good and easy to use. Not only that, the interface of the entire system was also very simple and full of high-tech fashion sense... It seemed that the little angel was worthy of being an all-purpose angel for electronic warfare. She was indeed a professional in information processing.

"Um... this is the communication column..."

Fang Zheng tried to call up the address book and soon found that there were already several people's names on it, including Nymph, Tilia, Hecate and almost everyone else.

"Hmm...how should I put it..."

Looking at the list of names in front of him, Fang Zheng curled his eyes. Although this was actually normal, why did he always feel like he was flipping through the cards?
