Wu Xiaode squatted on the window sill and looked down.

Satan is wearing a black shirt and black-rimmed glasses, with a gentle appearance, and is typing on the keyboard.

Next to him was some kind of huge organ.

"Hi."

Wu Xiaode said hello.

Satan seemed to know what he was thinking, explaining:

"Don't touch that thing. I got it with great difficulty - the core of the prehistoric troll. As long as it is given energy, it can multiply indefinitely and never die."

"This thing can also be used as a biological mecha?" Wu Xiaode asked curiously.

"We are trying," Satan tapped the keyboard without raising his head, "We will talk later, my analysis here is entering a critical stage."

"do your stuff."

Wu Xiaode jumped down from the window sill, walked through the research room, and walked all the way to the structure room at the back.

The structure room is very spacious and filled with all kinds of strange biological structures.

Even though Xia Huilan has the technology of biological mechas, she can't get these things.

It seems that Satan, the "learning devil", can indeed play a complementary role by joining the research on biological mechas.

Wu Xiaode walked all the way to the end of the structure room and saw the scene shown by the "reality"——

A floating blank photo frame circled around Xia Huilan, making an intimate voice:

"Good sister, just sign a contract with me. I am great, unique, and number one in the world."

"do not bother me."

Xia Huilan wore goggles and said impatiently while collecting data on a certain bone claw.

"Why did you reject me?" the blank photo frame asked crying.

Xia Huilan said vigilantly:

"Who knows what you are? Even Satan can't see you, and any of my attacks won't be effective against you -"

"Do you really think I'm so easy to deceive?"

Wu Xiaode grinned.

"Sister Lan."

He shouted.

"Xiao Wu?"

Xia Huilan turned her head, a look of joy suddenly appeared on her face, walked quickly to Wu Xiaode, and grabbed his hands.

She was about to speak when she suddenly took a step back and said calmly:

"I'm doing a very crucial experiment here. Xiao Wu, please go out first and come back in a few days."

Wu Xiaode grew up with her, and seeing her expression change so quickly, his heart became clear.

——She met the heroic spirit in the shape of a "picture frame". She couldn't tell whether it was an enemy or a friend at the moment, and she was afraid of hurting Wu Xiaode, so she spoke like this.

Sister Lan is really stupid.

But I like it.

Wu Xiaode chuckled, regardless of the majesty and serious look on her face, he hugged her directly and whispered:

"Don't worry, Sister Lan, the photo frame behind you is your friend."

Xia Huilan was startled, and her stiff body gradually softened.

——She believed it.

She took off her goggles, leaned on Wu Xiaode's shoulder, and said depressedly:

"Everything is changing too fast. I don't know where this era will go."

"Sister Lan, what are you worried about?" Wu Xiaode asked.

"I often think back to those days when we were dependent on each other - how wonderful it would be if we could go back to the past." Xia Huilan said.

Wu Xiaode gently stroked her hair and remained silent for a few breaths before saying:

"We can't go back, Sister Lan."

Fortunately——

He went to heaven and earth and tried his best, from the Death Cave to the past era, and killed several people in and out of the World Destruction Council. He even earned the recognition of the Human Emperor and personally bestowed the inheritance.

Everything is ready.

Now, the times are beginning to slide in an irreversible direction, and the power that I can bring to everyone has emerged.

No need to miss the past anymore.

Just keep those painful and humble days in your heart forever.

Times are about to change.

Go fight.

Go for everything you want!

Wu Xiaode's eyes were full of fighting spirit, and he even involuntarily hugged Xia Huilan tighter.

Xia Huilan raised her head and glared at him gently with a pair of beautiful eyes.

Her hands slid down deftly and lifelessly, and slightly twisted around his waist.

"What do you mean by hugging me so tightly? Huh?"

Xia Huilan asked with a half-smile.

Wu Xiaode naturally realized that something was wrong and said quickly:

"Sister Lan, no matter how the world changes, I will always be by your side to protect you from wind and rain. I will marry you in the future, learn new things with you every night, and strive to continue the family lineage."

When Xia Huilan said the first half of the sentence, she still thought it was a rustic love talk, but she couldn't hold back her laughter. After hearing the second half of the sentence, she just used her hands hard——

Wu Xiaode burst out with a scream like a slaughtering pig, and quickly changed the topic:

"No, Sister Lan, listen to me - I got a good thing this time, and it's this thing behind your back."

Xia Huilan accepted the offer and asked:

"Oh? Even Satan can't see it, but you can? What exactly is it?"

"This is a heroic spirit!"

Wu Xiaode pointed to the photo frame and said.

Xia Huilan looked at the photo frame with him.

Is this a heroic spirit?

Shouldn't heroic spirits be... dead heroes?

How does this photo frame look like a heroic spirit?

The photo frame suddenly jumped up and said loudly:

"Brother Xiao Wu is right. I am an extremely rare mysterious heroic spirit. Sister, please sign a contract with me quickly, or I will return to the spirit world!"

"Do you know each other?" Xia Huilan looked at the photo frame and then at Wu Xiaode.

Wu Xiaode spread his hands and said:

"I know it is a heroic spirit, but...I am not sure...because before..."

He didn't know what to say.

There were 1999 heroic spirits in my body before. How could I know who they were?

The photo frame became anxious and kept saying: "Brother Xiao Wu, I was controlling one of your parts at that time, have you forgotten?"

A part?

Xia Huilan's face was full of questions.

"Which part?" Wu Xiaode asked.

"Left Ear! When you fell into the abyss to look for the Death Key, it was I who heard where the Death Key was buried!" the photo frame said loudly.

"It turns out to be you!" Wu Xiaode suddenly realized.

"Please let this young lady sign me up, otherwise I will go back, please!"

A heart-warming gesture appeared on the photo frame.

"Sign it, it should be quite strong, and it can help you become stronger." Wu Xiaode said.

"Becoming stronger? Of course I am willing, but I'm just afraid of being cheated, but since you can trust it -"
