The entire sect is obsessed with love, but I'm the only one who's truly insane.

As they got closer, Lin Du realized that it really was a building.

The tree trunk was incredibly tall. In the morning, the slanting sunlight shone through the lush foliage, and the light and shadow falling on the trunk created natural patterns, much like... runes.

Tiangonglou, where every corner is a testament to nature's artistry.

From a distance, everyone could only see that Lin Du did not enter the Tiangong Building, but stayed under the tree, holding a small booklet, writing something.

"Sister... do you think Master Lin Du can do it?" the Feng family head asked in a low voice.

Feng Yi crossed her arms. "I don't know, but I have to give it a try."

Suddenly, everyone felt a little disappointed.

Because Lin Du didn't enter the Tiangong Building for a long time, he was just writing something down with a pen.

Time passed little by little, and the sun gradually rose to its zenith, and then began to set in the west.

The Feng family went from being tense and expectant to gradually dispersing and then becoming lost in thought.

The elders were able to hold back at first, but after the moon came out, they finally couldn't keep it up.

"Should we keep watching? Or maybe we should wait until they leave before coming back?"

After thinking about it, everyone agreed and turned to go home.

Only Feng Yi remained in the same place.

When the head of the Feng family returned after finishing his business, he found his older sister still standing there.

"Sis, are you going to stay here? You've been standing here all day. I thought you were going to take root here."

Feng Yi turned around and gave him a cold look. "They've all left. Someone has to stay and watch over them."

The head of the Feng family scratched his head sheepishly, "Isn't it because you're watching over things?"

He admitted his mistake, "I was wrong. Sis, would you like some snacks? The ones from Qilin Pavilion on Fengyu Street are fresh out of the oven, hehe, they're still warm. You used to bring them for me every time you came home when we were little."

"That's because it's on my way, and I didn't want to go home empty-handed." Feng Yi was still standing.

The next moment, Feng Ji started rummaging for stools and a coffee table, then brought out the brewed tea, saying, "Please."

Feng Yi then sat down leisurely and drank tea.

"Sis, what is Lin Du doing? Everyone else went in but came out because they didn't answer correctly, but Lin Du hasn't gone in yet."

Feng Yi was sitting there, drinking tea with an air of nobility and elegance, completely ignoring what was happening.

Feng Ji was already used to it. He found a small stool, sat down next to Feng Yi, and took out another bag of pastries that wasn't in the carved food box. He figured he should save money where he could and spend it where he could. If he was eating them himself, he didn't need fancy takeout boxes; he could just wrap them in oil paper.

The two of them stayed there all night, but Lin Du remained in the middle of the lake the whole time.

A day and a night passed before Feng Ji finally woke up from his nap and looked up to find Lin Du gone. His sleepiness vanished instantly, his eyes widened in shock, and he patted Feng Yi hard, crying, "Sister! He's gone!!!"

"Did Lin Du run away?!"

Feng Yi stepped aside with a look of disdain. "She didn't run away; she just went inside."

Feng Ji was taken aback. "How long have you been inside?"

"A quarter of an hour."

Feng Ji jumped up in shock, knocking his small stool to the ground. "A quarter of an hour? That's a record!!"

For the average person, going in is almost as short as taking a sip of tea to appreciate the flavor before leaving.

Feng Yi lowered her eyes, calmly tapped the tea table, and said, "Make some tea."

Feng Ji's face lit up with joy. "Eh!"

A quarter of an hour ago, Lin Du drew all the symbols cast by the sunlight and moonlight, only to find that she had indeed guessed correctly.

Although her reading scope in talismanic arts was not extensive, she was well-versed in history books and basic books on runes, and had been baptized by divine runes, so she was particularly sensitive to these lights and shadows.

Runes originate from nature, and each complete rune, like an array, requires a closed energy loop; some discernible patterns can be observed within it.

From the moment he saw the Tiangong Building, Lin Du, who was familiar with interpreting the questions, already understood the main theme of the building.

Especially when she discovered that new rune lights and shadows would appear after a fixed time interval, her conjecture became supported by evidence.

So Lin Du recorded all the changing runes one by one until the next day arrived.

The next morning, at the exact moment she arrived the day before, the first rune she had recorded appeared as expected.

Lin Du's conjecture has become a reality.

Tiangong Tower is indeed a masterpiece.

So Lin Du put away his notes, raised his hand and followed Feng Yi's instructions on how to enter the Heavenly Crafts Pavilion, opened the barrier, and entered the Heavenly Crafts Pavilion.

Upon entering, Lin Du found himself inside a tree, a feeling similar to, yet different from, that of sleeping in a treehouse in the demon realm years ago.

Because the spiritual energy of heaven and earth within this building is straight and unobstructed.

It turns out the tree wasn't a tree at all, but a building.

The next moment, Lin Du was put to the test.

"Please draw the runes that can summon the most malevolent yin energy."

Lin Du quickly picked up his brush and drew the rune that appeared after noon.

Noon is the time when the yang energy between heaven and earth is at its peak. After that, yin energy will begin to emerge. The wisp of yin energy that appears at noon is naturally the most ominous.

In ordinary talisman books, this is called "ghostly energy".

We passed this hurdle smoothly.

The questions that followed became increasingly tricky. Lin Du thought about it carefully and realized that the time interval between each rune was exactly the same as the time interval between each small grid that was divided when the first sundial appeared.

Time, yin and yang, seasons, heaven, earth, wind, thunder, water, fire... connect these to their origins and the records in ancient calendars, and guess the runes that are most likely to appear at the time related to the topic.

Time passed little by little, and before Lin Du knew it, his divine sense had been exhausted and then replenished.

Finally, this is no longer a problem.

"Why have you come to claim the legacy of the ancient gods? And if you obtain it, how will you pass it on?"

Lin Du stood up and thought for a moment. Feng Yi's persistence was not because she couldn't enter the Heavenly Crafting Tower, but because... no one could inherit the ancient god's talismanic legacy, and the lineage had been broken.

She thought of her senior brothers and sisters who had taught her. She was not their disciple, but they had taught her their most treasured skills.

She thought of her master Yan Ye, who had helped her reverse her fate that day. What they passed down from master to disciple was their unique skills and their character.

"We should carry on the lost teachings of the sages." Lin Du raised his face, "and pass them on to all who can understand and desire this legacy."

She once made regular donations to education projects in remote areas, and she also stood on the loess soil, wanting to "help the world when one is successful".

Education should be provided to all without discrimination, and the torch should be passed on to ensure the continuation of lost knowledge.

She didn't know if this answer would mean losing this opportunity in a world that values ​​master-disciple relationships and family lineage, but it was her own answer.

Long, long ago, when Lin Du was still relying on the charity of others, she once saw a passerby boasting about finding an unexpected martial arts manual at a street stall. But later, she saw that the person failed in practicing the manual and went into a state of demonic possession; it turned out to be a fake manual.

She thought, if only everyone could receive the right education.

Later, Lin Du really did encounter compulsory education; it turned out that even in university, books were still very expensive.

She thought that at least those who needed it and could understand it could learn the professional knowledge they longed for.

This is the legacy that Feng Yi wanted to see, the legacy that the Feng family and many talisman masters wanted to see, so this legacy should be shown to these people.

She will come up with a better and broader way to pass it on.

She heard the sound of flowing water.

The sound came from all directions, yet there was no trace of water.

Outside the Tiangong Building, the teacup between Feng Yi and Feng Ji began to vibrate, making a crisp porcelain sound.

The two looked up at the same time and found that the lake water was slowly receding.

Or rather... it's as if the roots of the great tree that is Tiangonglou are drawing water from it.

As the lake level continued to drop, the Tiangong Building gradually revealed its jade-like luster.

Feng Ji's breathing quickened. "Sister..."

This time, Feng Yi's hands trembled. "This...it's done?"

"It's done!!! It's done! Someone! Someone has started the inheritance!!" Feng Ji shouted, his face beaming with joy.

"It was Lin Du who initiated the inheritance." Feng Yi stood up straight and smiled proudly. "I knew she could do it."

The ancient divine inheritance within the Heavenly Craft Tower is the most primitive talismanic art, the most primitive painting, and even the most primitive powerful writing.

"Sister...why are you trembling?"

Feng Yi lowered her eyes and realized that her hands under her wide sleeves were trembling slightly. This time, however, she did not try to maintain her dignity and make an excuse.

She lowered her head and laughed, "It's nothing, I'm just happy."

So this is what it feels like to have your wish fulfilled.

The backflow of lake water did not happen overnight, nor was the absorption and inheritance of knowledge and skills accomplished in a single day.

Lin Du never expected that this Tiangong Building would actually hold quizzes and a graduation exam.

She didn't even know how many days had passed. Every day, when her spiritual consciousness was full, she would start learning the inheritance; when her spiritual consciousness was depleted, she would close her eyes, meditate, and absorb spiritual energy.

The building was suspended in mid-air, yet she didn't need to use her spiritual power to maintain it. It had a rich spiritual aura, similar to the scent of a lake, but she couldn't find any water vapor.

During his diligent study, Lin Du finally found the reason.

It turns out that the art of talismans is so profound that it can turn water into water and summon spirits with a single talisman.

The runes she had previously recorded were the foundational runes of this inheritance.

It's even simpler than their formations. Although it consumes more of one's own spiritual power and divine sense, and has requirements on one's realm and physical endurance, it is indeed faster to use.

Lin Du also had to cultivate from the mid-stage of the Qian Yuan Realm to the Great Perfection of the Qian Yuan Realm because drawing a single talisman would consume all his spiritual power.

Fortunately, the building was filled with spiritual energy, enough for her to concentrate on absorbing and cultivating.

After she had intermittently completed the major exam and thoroughly learned the inheritance, she came out and found herself standing in the middle of a large pit, with only tree roots under her feet.

She paused for a moment, then said, "Who drank all the water? Chu Guanmeng, was that you?"

Chu Guanmeng bared her teeth, "You're slandering an innocent person!"

Lin Du held back the fur ball that was trying to come out. "Seventeen years. Talismanic arts are much harder to master than arrays."

"Really? But some people studied array formations until they were over fifty years old before becoming the master of array formations. You completed the inheritance of an ancient god in just seventeen years, which is much faster than I thought." A familiar female voice rang out.

Lin Du straightened his back reflexively, "Seventh Senior Sister!"
