In the space, the Jianmu sapling, after many years of growth, finally sprouted a new tender leaf.
There were now a total of four leaves: two large, oval leaves, about the size of eggs.
There was also a tender leaf the size of a copper coin, and a sprout the size of a soybean.
It was unknown how many years it would take for this Jianmu to grow to the heavens.
Xiao Fei glanced at the Jianmu sapling, then at the small gourd, before walking towards the place where "Zhu Yan Bai Gu" was planted.
The area around "Zhu Yan Bai Gu" was completely sealed by him with a spiritual energy barrier to prevent the poisonous gas from leaking.
Xiao Fei entered this sealed space, and the land was completely dyed pink.
The fifth round of growth for "Zhu Yan Bai Gu" had concluded, its petals withered and fallen to the ground.
Xiao Fei approached and picked up these petals, placed them in a box, and then sealed it with several layers.
He capped the jade bottle filled with venom and tucked it into his embrace.
The toxicity of the poison emitted during the fifth round of growth for "Zhu Yan Bai Gu" should be much stronger than the fourth round.
It was a pity he hadn't found an opportunity to test the poison on a cultivator in the Integration stage.
During the last great battle with the undead, he hadn't even used "Zhu Yan Bai Gu" before the opponent was routed and fled, and he couldn't catch up.
There were still dozens of Integration stage powerhouses in the Tian Yuan Realm, but they had no enmity with him, so he couldn't bring himself to act.
For now, he could only pour this venom into the Demon Sealing Well on the Eastern Continent, letting the demons test its potency.
Before the last battle, he had already planned to return to the Eastern Continent, but he was delayed by the war.
By this year, the natural formation within the Absolute Spirit Locking Heaven Great Array would open again.
He planned to return and check on the situation of the Eastern Continent.
Additionally, the Spirit Transformation Grass he had planted in his space had already cultivated a large patch.
It could be transplanted to areas polluted by demonic energy on the Eastern Continent to improve the cultivation environment there.
When Xiao Fei emerged from his cultivation chamber, Xiao Lan, Huang Feifei, and Zhu Yu were already waiting for him outside.
This time, they had arranged to return together as a group of four. It was a shame Ji Wudi was missing, otherwise, they could have gone together.
Initially, Xiao Fei had intended to bring the嘯月老祖 (Xiao Yue Lao Zu), in case they encountered a powerful expert on the way, to have as a bodyguard.
Now that their strength had all improved, there was no longer a need for that.
Even Zhu Yu's little fox was not brought along.
The group quickly found the location of the ancient teleportation array. With a flash of light, the four of them disappeared.
When they emerged from the turtle island, they could clearly feel that the spiritual energy within this great array had become even more sparse.
With their current strength, it only took the time it takes for a cup of tea to boil to fly to Meteorite Island.
Meteorite Island was now a sacred land for humanity, extremely prosperous, through the spirit gathering array and the accumulation of resources.
The spiritual energy concentration on Meteorite Island was now sufficient to sustain the cultivation of cultivators in the early Nascent Soul stage.
However, other places were miserable, almost barren. Cultivating to the Foundation Establishment stage was already remarkable, making one a powerful figure, walking with pride.
As for the Golden Core stage, it was already a legendary existence, rarely seen, transcending worldly matters.
Meteorite Island was now governed by Huangfu Xuan, Fei Xin, and a few others. Upon seeing Xiao Fei's return, they were naturally overjoyed.
They prepared a grand banquet to welcome Xiao Fei and his companions.
Huangfu Xuan and the others were all cultivators in the Soul Transformation stage personally trained by Xiao Fei years ago.
In the years Xiao Fei was away, Meteorite Island had cultivated over a dozen cultivators in the Nascent Soul stage, but not a single one in the Soul Transformation stage.
With the current resources of Meteorite Island, it was simply unable to support a Nascent Soul cultivator to break through to the Soul Transformation stage.
"In the years we were away, has the demon race attacked again?" Xiao Fei inquired during the feast.
The passages to the demon realm on the Eastern Continent had always been a hidden danger, capable of erupting at any moment.
"The demon race only appears occasionally, one or two at a time, their strength is extremely formidable, far surpassing the Soul Transformation stage. They should be the legendary Void Refinement stage."
Upon hearing this, Zhu Yu deliberately leaked a trace of Void Refinement stage aura.
"Mere Void Refinement, nothing to be concerned about."
The mere trace of aura he leaked caused everyone present to drop their chopsticks.
Then, they cast envious glances at Zhu Yu and the other three, like country bumpkins.
In such a short time since their departure, they had already reached the legendary Void Refinement stage.
Fei Xin regained his composure and continued.
"However, those demons who crossed the passages were all killed by that 'Bloodthirsty'."
Xiao Fei heard this and could roughly guess the cause and effect.
He had thrown so much "Zhu Yan Bai Gu" into the passages, it wasn't for nothing.
Any demon below the Void Refinement stage would be poisoned to death halfway through attempting to cross.
Those in the Void Refinement stage or above could resist "Zhu Yan Bai Gu" by taking detoxification pills, but after barely passing through, they would emerge from the Demon Sealing Well with only half their lives left.
Then, a demonic blade called "Bloodthirsty" would specifically exploit their weakened state, harvesting their vital essence and lives.
"You can make some preparations. When we leave next time, you few can accompany me to the Tian Yuan Realm. The spiritual energy there is denser and more suitable for cultivation beyond the Soul Transformation stage."
Huangfu Xuan and Fei Xin were overjoyed upon hearing this. They had longed for it, and now they could finally go to the Tian Yuan Realm.
"Thank you, Senior Brother!"
"No need to be polite. I have some pills and other resources here. Take them and strive to cultivate one or two Soul Transformation cultivators within these decades, so they can take over this island."
For a period afterward, Xiao Fei and Huang Feifei traveled across various parts of the Eastern Continent, planting Spirit Transformation Grass in places contaminated by demonic energy.
This demonic energy originating from the demon realm would eventually transform into spiritual energy.
In addition, he poured large quantities of "Zhu Yan Bai Gu" venom, which had reached its fifth round of growth, into every Demon Sealing Well.
Then, he tightly sealed the entrance of the Demon Sealing Well, preventing any trace of aura from leaking.
The "Zhu Yan Bai Gu" poison he threw into the Demon Sealing Well would spread towards the demon race through the passages between the two realms.
He had previously poured a lot of poison into the passages, and these poisons continued to spread within. Eventually, some of the poison would head towards the exit of the passage on the demon realm side.
Now, these 36 passages leading to the Tian Yuan Realm had become dreaded, perilous places among the demon race.
Anyone who ventured into the cross-realm passages had never returned alive.
This also led to the demon race's exploration of the Tian Yuan Realm making no progress.
Those with too low cultivation exploring the passages now could only be sending themselves to their deaths, serving no purpose.
Several batches of Void Refinement stage demons had been dispatched, but there was still no news.
Since even Void Refinement cultivators did not return alive, the remaining Integration stage demons naturally dared not risk their lives. It would be a great loss if they died inside.
