Guixu Palace, central courtyard.

This is an open-air courtyard with an intricate Guixu formation painted on the ground. It looks like a rotating kaleidoscope, with constantly changing dazzling lines and structures.

Above the head, there is a deep and endless ravine. The endless sea water forms a dark and lightless "night sky", which makes people feel daunting and fearful.

The only source of light, apart from the light projected from the windows of the surrounding side halls, is probably the light of the Guixu Array itself - the spells and silver threads that make up the array also glow.

Luo Yan did not rashly step into the courtyard, because there were many cultivators observing the formation from behind the windows. Even if he just stepped on it and blocked the view of a few of them, it might cause a violent reaction from the demonic person.

You know, crazy people are unreasonable!

Therefore, he just walked carefully along the open area surrounding the formation and came to the pile of wood in the corner.

Judging from the texture of these woods, they seem to have been cut down from an abandoned garden in the backyard and piled up casually in the corner.

Luo Yan used his spiritual sense to penetrate into the cracks in the wood and carefully examined it, but did not find anything unusual.

It seems to be just an ordinary piece of wood...but why does it have the ability to resist sinking into a huge ravine?

"We need to do an experiment." Luo Yan said, taking a piece of wood here.

"What?" Miss Shi was caught off guard and didn't hear clearly.

She had been a little distracted all the way, with her mind filled with all kinds of random thoughts:

For example, if the two of them were really trapped here for hundreds of thousands of years, and in order to resist the passage of time, he and his junior brother decided to become Taoist couples. Should they have children later?

In the world of immortal cultivation, cultivators who become couples can choose to have children or not, depending entirely on their personal preference.

For Shi Liuli, on the one hand, it was the subtle influence of the family environment (Elder Shi Ding was obviously not a person who advocated not getting married or having children), and on the other hand, he was also worried that his junior brother might change his mind in the future. If he could have a child, would it be possible to tie him down better?

Luo Yan certainly didn't expect that this young lady with an unconventional mind would even start to consider whether to have a baby after being trapped here, so he patiently repeated his thoughts again:

"At present, it seems that in addition to the Guixu Palace itself, the wood used to make the Sanyu Treasure Ship can resist the sinking trend in the Great Ravine."

"If studying the Guixu Formation directly does not yield any results, we can also try studying these pieces of wood. Simply put, we can first go to the backyard and get the same wood, and compare it with the wood piled near the formation to find the differences and similarities between the two."

Shi Liuli understood this time, so she said "oh" obediently, thinking to herself that she should be able to be a good wife and mother, right?

No problem! Liuli, you can do it!

Luo Yan felt a little surprised when he saw this. He had to know that when had this Miss Shi ever shown such a well-behaved and docile attitude in the past?

Even if he agreed to my request, it was because "I think it's very interesting" rather than "because this is the request of my junior brother."

So he guessed that Miss Shi was really scared this time, so he held her hand and comforted her:

"Don't worry, Senior Sister, we will definitely be able to get out of here."

At least I can go out...

When he held her hands, Miss Shi had the shy urge to break free, but then she thought, if she was trapped here, what else could she do except be with her junior brother? So she could only turn her head away and nodded imperceptibly.

Luo Yan found it even more strange. Miss Shi's sanity was too short. How long have we been here? She couldn't take it anymore?

Forget it. After all, she is a mentally minor, so we can’t blame her too much.

Luo Yan took her to the backyard garden and walked around the edge for a while, and noticed that there were indeed signs of logging in some areas.

Apart from that Zhunmang Jun, I guess no one else would cut down trees here... huh?

"Who!" Luo Yan suddenly shouted loudly, and the hand in his sleeve had already released Taoist magic, which scared Shi Liuli so much that she quickly hid behind him.

However, the person who ran out of the woods was not a malicious villain, but a crazy old Taoist priest.

"Useless! Useless!" He laughed loudly. "There are new people studying wood. Don't they know that if they build a boat without people on it, it will float, but if people on it, it will drown? This is a dead end, this is a dead end!"

The old Taoist priest ran away crying and laughing, leaving behind only Shi Liuli who looked confused and Luo Yan who looked gloomy.

Luo Yan also heard the other party's crazy words clearly:

He said that pioneers had already tried to study treasure ship timber.

Perhaps it was because of the huge ravine at this location, and the sealing force was too strong. If a boat was carved from wood soaked in the power of the formation, it would only float up when no one was on board.

Once someone sits on it, it will not be able to bear the weight and will continue to sink.

On the other hand, the Guixu Palace can float steadily in this position no matter how many cultivators come in it. This is enough to show that the two are not at the same level in terms of resisting the sinking force of the great ravine.

Luo Yan cut several pieces of wood from the backyard garden and brought them back to his residence, and began to compare them with the wood near the Guixu formation in the courtyard.

From the outside, there is really no difference between the two.

But if you use your spiritual sense to scan the interior, there are subtle differences when comparing:

The distribution density of wood fibers in the backyard garden has an obvious pattern. This is because when woody plants grow, they will produce corresponding "phototaxis changes" according to the direction of the surrounding fixed light sources.

The distribution density of wood fibers in the wood near the Guixu formation in the central courtyard is chaotic, and there are no similar changes.

There are two experiments to be done next: one is to carve the wood in the backyard into a treasure ship, and apply the "phase technique" in the formation to make it rapidly grow larger after leaving the water film - as a control group to see if it can successfully float up.

If not, it proves that the buoyancy is not caused by the nature of the wood itself, but by the Guixu formation in the courtyard.

Secondly, the distribution of wood fibers inside the wood in the central courtyard must be "refreshed" and arranged using the wood-related divine light from the acquired five elements' great extinction divine light, and then see if it can float.

If not, it proves that the treasure ship's ability to float is related to the distribution of this wood fiber inside it!

Luo Yan was concentrating on designing an experiment when he was suddenly hit in the face by a hair.

He turned around in confusion, only to see Miss Shi Liulishi, who had tied her hair into two ponytails playfully and was swinging them around out of boredom.

“…Senior Sister.”

"What's wrong, Junior Brother?"

"Don't interrupt my train of thought, thank you."

Shi Liuli was stunned for a long time, then immediately became furious:

Senior sister, I haven't even married you yet, and you're already starting to dislike me? My father isn't here, and you're too lazy to even put on a show, right?

Her face was as gloomy as water, and a cold light flashed in her eyes. She quietly circled behind the unaware Luo Yan, suddenly stretched out her right arm to hug him in her arms, and suddenly grabbed his neck and lifted him up.
