"Stop!"
Gu Xun'er's soul power was stronger than Lin Xian'er's, so she discovered the deep pit ahead in advance.
Wisps of black wind blew out from the deep pit, carrying the surrounding air and constantly compressing towards the pit.
If one blindly followed the airflow, they would be dragged into the abyss and unable to escape.
Hearing Gu Xun'er's voice, Lin Xian'er immediately stopped.
"Xun'er, what's wrong?"
"There's a trap ahead, don't be careless."
Gu Xun'er's voice was solemn. She formed mysterious seals with her hands and struck forward.
Boom!
A golden palm print swept over the deep pit, briefly illuminating its location.
The airflow above converged around the deep pit, forming a face wailing like an evil ghost.
"Such strong Yin energy!"
Even possessing the Gold Emperor Burning Heavens Flame, Gu Xun'er felt a trace of chill.
It was a fear that made one's heart tremble.
Gu Xun'er silently recited the clan's scriptures in her heart, calming the fluctuations in her soul.
Lin Xian'er was stopped by Gu Xun'er just now, so she didn't face the wind like an evil ghost directly.
"Gold Emperor Burning Heavens, Majestic Sword Might!"
Gu Xun'er summoned a golden long sword in her hand and slashed into the deep pit.
The golden sword qi overcame all obstacles, cutting through the black wind along the way.
The black airflow, originally waiting for the two girls to fall into the trap, saw Gu Xun'er's divine might and took the initiative to attack.
"Retreat quickly!"
Within one move, Gu Xun'er had roughly understood the strength of these black winds, which was at least at the Seven-Star Dou Ancestor level.
This was only the starting position of the deep pit. If they continued deeper, the strength of the storm would only get stronger.
"Mr. Han's guess was indeed correct; the formation of the black storm has another reason."
If it relied solely on the natural environment, it should have spread from the Black Sea.
Being born directly from the inland and continuing for years, it should be the black gas in that deep pit playing tricks.
The violent wind rushed towards the two girls, then was shattered by the golden greatsword.
Gu Xun'er and Lin Xian'er quickly withdrew from the cave entrance. The pitch-black storm seemed to be sealed by some power. When it reached the cave entrance, its power suddenly weakened, only able to stir up some subtle black airflow around the entrance.
"Let's go back and notify Mr. Han. We can't solve the matter here with just the two of us."
Gu Xun'er said sensibly.
Lin Xian'er agreed.
If they messed up and got themselves into trouble without knowing the danger, they would probably be lectured by Master again.
Feng City Bamboo Pavilion. Han Feng, who was writing in the study, saw the two girls run into the room as if carrying the wind.
"What's wrong, in such a hurry?"
"Mr. Han, we found the source of the black storm!"
Gu Xun'er said excitedly.
"Oh?"
Han Feng smiled and said: "It's only been a few days; you guys are quite efficient."
Originally, he didn't care too much about the black storm. After all, he hadn't lived in the Black-Corner Region for long, and Feng City had a superior geographical location and was stable all year round, with almost no natural disasters. Han Feng didn't need to worry about the source of the storm.
But now that the Black-Corner Region had become his territory, and seeing many small towns devastated by the black storm along the way this time, he had the intention to govern it.
"Where did you find it?"
"A cave entrance deep in the Black Sky Gorge."
Gu Xun'er said.
"Ah?"
Han Feng was slightly stunned.
The Black Sky Gorge was quite a distance from the Great Plains. Unexpectedly, the source of the black storm came from there!
"After finding the source, we discovered very strange black wind inside, so we didn't continue deeper."
Lin Xian'er added at this time.
Han Feng nodded.
"Finding it is enough; no need to take risks."
"I'll take some time to go there later."
As a Dou Saint, stabilizing a mere source of a black storm was a piece of cake.
"Master, where are Qing Lin and the others?"
When Lin Xian'er entered the bamboo pavilion, she didn't find anyone else.
"Them..."
A helpless smile appeared on Han Feng's face.
In these few days, Qing Lin and Mu Qingluan traveled around, helping those in need when seeing injustice, and made quite a name for themselves.
Two underage girls possessed strength comparable to the top of the Black Ranking.
Many veteran Dou Emperors were no match for them.
With such a combat record, it didn't take long for the fame of the two girls to spread wildly in the Black-Corner Region.
"You two probably came back too quickly. Now, just ask around in the surrounding cities, and you can hear the title 'Green Heroine Duo'."
"Green Heroine Duo?"
Lin Xian'er's expression was a bit strange. What kind of title was this?
"Let them be."
Han Feng said.
"By the way, what about Zi Yan? Did she go back?"
"No, she is currently in retreat at Jia Nan Academy."
Lin Xian'er was somewhat surprised to hear this.
Zi Yan in retreat?
Did the sun rise from the west?
That playful little girl actually took the initiative to retreat now.
For a moment, Lin Xian'er also reflected in her heart whether she had been slacking off recently.
"Master, you busy yourself first; we're going back to cultivate."
Lin Xian'er said.
"Go ahead."
Han Feng smiled.
Comparison can sometimes become motivation.
The two girls returned to their respective rooms to start cultivation.
Han Feng was not idle either. Although he was writing in the study, every stroke contained profound spatial laws.
Besides delving into the path of space, he was also comprehending the time law inheritance left by the Azure Dragon.
These two paths were already quite difficult, and eventually needed to be converged and fused into time-space laws. Han Feng had no clue at all now.
Fortunately, the Azure Dragon Common People Formula and the Black Tortoise Heavenly Ancestor Sutra were steadily improving. The Green Lotus Core Flame and the Sea Heart Flame played a significant role in this.
The deeper he studied these two cultivation methods, the more mysteries Han Feng could discover in them.
Take the Mantra of Flame for example. This magical technique, as Han Feng's main cultivation method, theoretically couldn't be practiced together with other techniques.
It naturally possessed domineering exclusivity.
Like Xiao Yan, who gave up halfway and wanted to switch cultivation, he still needed to cripple part of his cultivation.
But the Black Tortoise Heavenly Ancestor Sutra and the Azure Dragon Common People Formula did not trigger the rejection reaction of the Mantra of Flame.
They could coexist with the Mantra of Flame.
This was something other cultivation methods in the world didn't possess.
Even Heaven Rank ones wouldn't work.
Now, Han Feng mainly cultivated the Mantra of Flame and concurrently cultivated two divine beast techniques. The speed of Dou Qi improvement was at least double that of before.
This was also the reason why he was so confident before that he could climb to high-level Dou Saint within twenty or thirty years.
Things that other geniuses needed a hundred years to complete, he might only need fifty years.
If he collected the four divine beast techniques and fully comprehended them, perhaps this time would be even shorter.
This method should be useful for others too, but it was very difficult for ordinary people to comprehend divine beast techniques.
Like the Sikong Imperial Family of the Nanli Empire, passed down from generation to generation. In Sikong Chan's generation, with such talent, she still only comprehended half of the Vermilion Bird Pure World Scripture.
The benefits after comprehension were obvious, but the time spent on comprehension was more than a hundred years.
A family with a heritage of ten thousand years couldn't achieve it, let alone ordinary people.
Only geniuses truly standing at the apex level of the continent had the opportunity to comprehend the corresponding mysteries.
The last stroke ended. The brush tip flickering with faint silver light was gently lifted. On the rice paper made of special spiritual grass, upright and stylish black characters were arranged one by one.
At first glance, it looked ordinary, just a common calligraphy work.
But if observed carefully, one would find that between the characters, it seemed to connect to endless space.
"Done."
After days of polishing, this mountain and river poem was finally completed.
Han Feng's soul power tried to penetrate into the paper. The next instant, his soul arrived in another fantasy world.
That was the mountain and river scenery under his pen.
Dou Saint experts could already shape space themselves.
Han Feng utilized this point, combined with the methods in weapon refining, to draw a calligraphy work containing a small world.
Everything in the world was built by Han Feng.
The poem was the description of the world. Whatever shape of mountains, whatever color of river water, all could be shaped.
Han Feng looked at the world created by himself in front of him and smiled slightly.
"Just call you, Mountain and River Record."
The scroll meticulously polished by Han Feng naturally wouldn't only have ornamental functions.
The Mountain and River Record could house living things and also trap enemies.
It could serve as an inexhaustible storage item and also play magical effects when facing enemies.
Han Feng withdrew his soul power, suddenly lifted the brush, and wrote a few big characters in the air.
"Wind, Rain, Thunder."
The big characters were imprinted in the air. A magical power emerged from the Mountain and River Record. Above the bamboo pavilion, wind and rain blew immediately, and thunder rumbled.
Han Feng stood in front of the window, looking at the scene before him, and nodded with satisfaction.
"Retract."
As the voice fell, the strange phenomenon in the sky dissipated instantly.
If not for the rainwater still remaining on the bamboo leaves, one would probably think it was an illusion just now.
This method was derived from the artistic conception of Two Fingers Transform Mountains and Rivers in the Heavenly Origin Finger.
But compared to the superficial Yin-Yang changes in the finger technique, the Mountain and River Record was obviously more advanced.
It could store various heaven and earth energies and release them when Han Feng needed.
Heaven and earth contain Yin, Yang, and all things. As long as the energy is sufficient, it can transform into thousands of things.
Of course, soul power was needed during conception. The greater the difference from reality, the more soul power was needed to construct it.
Once construction was completed, it wouldn't take too much energy to use it again in the future.
Han Feng tried writing a few other things, and the results all followed his wishes.
He couldn't help thinking that perhaps in the process of comprehending the path of laws, he had inadvertently created a new combat method.
Borrowing the power of heaven and earth to write what was in his heart.
Putting away the Mountain and River Record, Han Feng brewed over the gains and insights of these days.
Among them, Dragon Emperor Zhu Kun gave him the greatest help.
If he hadn't taught the spatial great dao of the Ancient Void Dragon clan, Han Feng couldn't have refined a treasure like the Mountain and River Record.
Next were some scattered wood laws and water laws.
These laws wouldn't serve as Han Feng's main cultivation laws, but they could provide him with more choices in future combat scenarios.
Laws also have mutual generation and mutual restraint. If a cultivator only masters one law, facing experts of the same level, they are often easily targeted.
Generally speaking, choosing one law as the main cultivation and cultivating two to three laws concurrently is the mainstream cultivation method for Dou Saint realm cultivators.
After all, Dou Saint experts have long lifespans, and realm improvement is too slow. If they only stick to one path, wouldn't it be too boring?
Of course, if one can walk to the peak on one great dao, that is also excellent.
Mutual generation and mutual restraint are only within a certain range. Beyond this range, fire can also overcome water.
Just like in the Hidden Dragon Cave last time, the Azure Dragon forcibly extinguished Han Feng's fire law with wood law.
