At this time, Xu Feng and the apostle opposite were both eagerly looking forward to being able to contact each other's secret realms as soon as possible.

In fact, if Xu Feng wants to upgrade his portable secret realm, he only needs to explore the seventh-level secret realm and obtain a seventh-level secret realm core to directly upgrade the portable secret realm.

However, the higher the level of the secret realm, the more difficult it is to obtain the secret realm core.

In his previous life, when Xu Feng reached level seven, he was unable to comprehend the artistic conception and could not advance to the secret realm, so he began to frantically explore the level seven secret realms. He explored at least hundreds of them, but only two level seven secret realm cores were available. It is conceivable how difficult it is to obtain a high-level secret realm core.

However, this was also related to the fact that Xu Feng was not very strong at the time. With his strength at the time, exploring the seventh-level secret realm and completing the main task had already consumed a lot of time and energy. How could he have the strength to find the core of the secret realm?

The only two times I obtained the secret realm core were because of good luck. I happened to get it when completing the main mission.

"How can I allow others to snore beside my bed? Even if it is not for the purpose of upgrading the level of the secret realm, I cannot let him develop unscrupulously beside me!" Xu Feng said in his heart.

…

"Thank you, master!" Xu Feng got out of the taxi, greeted the driver, and walked towards the community where his home was.

Just then, a trembling and familiar voice sounded from behind.

"Xiao Feng!"

Xu Feng turned around and saw that it was Song Yuqing.

"Aunt Qing, I'm back!" Xu Feng said with a smile, looking a little excited.

Snap!

Song Yuqing fell to the ground carrying two large bags of vegetables, opened her arms and rushed towards Xu Feng, hugging Xu Feng tightly in her arms.

"Xiaofeng, where have you been these years..." Song Yuqing cried, patting Xu Feng's back hard.

After a moment, Song Yuqing seemed to have thought of something. She pushed Xu Feng away and then began to frantically take out her cell phone from her body.

"Hello, is that brother-in-law? Brother-in-law, Xiaofeng, Xiaofeng is back! Woo woo~"

…

When Xu Nantian heard the news about his son, he immediately rushed back from the City Defense Office. Seeing Xu Feng safe and sound, Xu Nantian finally breathed a sigh of relief. The family sat around the dining table, quietly listening to Xu Feng talk about his experiences in the past two years.

"What, you, you are level seven?" Xu Nantian looked incredulous.

At this time, Xu Nantian was still at the peak of level three. In the past few years since Xu Feng disappeared, Xu Nantian had spent most of his time and energy tracking down Xu Feng's whereabouts, and had no time to care about his own level.

"Dad, why are you still at level three? You haven't made much progress in the past few years..." Xu Feng glanced at his father and said with a smile, "I'll bring you a low-level Mirror-Breaking Pill in a few days. You can upgrade to the middle level first. After all, you are the head of a department. It's not good to show off your low level!"

In his previous life, Xu Feng spent nearly twenty years to become a high-level apostle of level seven. However, those second- and third-generation apostles with sufficient resources, once they became secret realm apostles, could become high-level apostles of level seven in just a few years without having to explore the secret realm, just by accumulating resources.

However, the seventh-level high-level apostles are also the pinnacle of these people. After all, there is no shortcut to comprehend the artistic conception, one must comprehend it by oneself. Moreover, for such high-level apostles who have piled up resources, it is ten or a hundred times more difficult to comprehend the artistic conception than other apostles. Except for those who are truly dissolute, no one is willing to take shortcuts in this way and upgrade to a high level, because this is equivalent to cutting off the possibility of becoming a transcendent in the future.

However, during your own improvement stage, it is fine to use the Mirror Breaking Pill or the Advancement Pill occasionally.

"How dare you make fun of your dad, little brat!" Xu Nantian glared at Xu Feng. He still couldn't believe it. In just four or three years, how did Xu Feng advance from a low-level apostle to a high-level apostle!

"Are you still planning to return to the City Defense Office?" Xu Nantian hesitated for a long time and finally asked this question.

"Why, you don't want to be the director anymore and want me to take over?" Xu Feng smiled with his eyes slanted.

"Huh, what? Do you look down on me as the director?" Xu Nantian glared.

"Haha, forget it. There won't be any high-level secret realms near Songtao City. It would be a complete waste for me to stay here!" Xu Feng shrugged and said.

At this time in the previous life, Songtao City had already become a city of the undead. The lich Muledan used it as his base camp and almost built a kingdom of the undead. If it weren't for the appearance of Grubba, the Lord of Destruction, this kingdom of the undead might have been built by Muledan.

Thinking of this, Xu Feng couldn't help but remember that the current King of Destruction, Gruba, was still trapped in the Dead Man's Ditch, waiting for his Dry Bone Sword to rescue him.

In his previous life, Grubba eventually became a transcendent being, but now, he is trapped and is just a high-level monk, probably at level eight or nine.

"I still have to find time to go to the Dead Man's Ditch and complete this epic rescue mission!" Xu Feng thought to himself, "I've had the mission items for three or four years, but I haven't had the chance to complete it. In another three years, Gruba won't need the Withered Bone Sword and will be able to escape on his own."

…

Xu Feng rested at home for three days and finally decided to go to the Dead Man's Ditch to rescue Grubba first. After all, he was a high-level warrior who had comprehended the artistic conception, and he must have a lot of good things in his hands.

Dead Man's Valley, underground cave A tall figure was chained tightly to the rock wall. Under him, the magma was rolling and emitting thick smoke. The air was filled with a hot breath. Dark red stone pillars protruded from the magma, looking like a stone forest growing in the lava.

Although Grubba's body was bound at this time, he continued to absorb the power of fire from the lava. The air around his body was twisted violently, and the high temperature was constantly burning the chains that bound him. Although it seemed to have no effect, over time, the runes in the chains would be destroyed one day.

"Bato..."

Feeling the pain from the wounds pierced by the chains, Grubba let out a low roar. For so many years, only chanting the names of his enemies every day gave him the courage to persevere. Otherwise, Grubba's spirit would have collapsed long ago.

Grubba occasionally thinks of the young man who was guided here by him a few years ago. He wonders if the young man still remembers him after so many years, whether he is still working hard for the mission assigned by Grubba, or maybe the young man has already died!

"It won't be long before I can escape from here, Barto, wait for me!" Gruba slowly closed his eyes, feeling the strands of fire power circulating in his body, constantly corroding the chains in his body, and his heart was full of hope of escaping.

There is no wrong version in the 1619 book forum!

After an unknown amount of time, Gruba suddenly felt a familiar breath approaching the underground cave rapidly.

Soon, a figure appeared at the entrance of the narrow passage leading to the ground.

"Who is it? Who disturbed the sleep of Grubba, the King of Destruction!" Grubba let out a low roar, and the magma in the cave began to boil violently.

Boom! The magma was surging, the heat waves were rolling, and a roar like thunder was heard in the cave.

"With emotions, you can mobilize the energy of the world..." Xu Feng stood at the entrance of the passage, with a gleam in his eyes, and whispered: "I underestimated your strength before, Gruba, you have already touched the realm, what a pity, what a pity..."

Artistic conception affects oneself and the enemy, while domain can affect the surrounding environment! With a thought, the sea turns into mulberry fields, the mountains turn into swamps, and the scorching summer turns into winter frost, snow and rain. This is the power of domain!

However, Grubba's strength seemed to be sealed by something. The reason why he was able to mobilize the lava in the cave with his emotions was that it had been sealed here for hundreds of years. Every inch of this cave was imprinted with his breath.

If he were to change to another place, there would be no such effect at all, and the surrounding environment and energy would not be controlled by him! "Gruba, do you still remember me?" Xu Feng smiled, and with a light jump, his figure floated in the air and slowly flew towards Gruba.

Seeing Xu Feng flying by himself, Gruba's expression was stern.

High-level monk!

Those who can fly in the air without relying on external objects and rely on their own cultivation are all high-level monks! "Who are you? Are you sent by Barto to kill me..." Gruba roared loudly.

Xu Feng was speechless and directly took out the withered bone sword from the space package.

"Gruba, do you recognize what this is?" Xu Feng flew in front of Gruba, raised the withered bone sword and shouted at him.

At this moment, Grubba, who was full of anger, suddenly froze, staring at the strange-shaped weapon in Xu Feng's hand with wide eyes! "Dry Bone Sword, you are holding the Netherworld Dry Bone Sword!" Grubba shouted, and then he looked towards Xu Feng, and instantly regained a trace of clarity.

"I recognize you, you are the human who promised to help me a few years ago!" Grubba was shaking with excitement, the chains on his body made a "clattering" sound, and dark red blood slowly seeped out from the wound, but Grubba seemed not to notice.

"Human, use the Withered Bone Sword quickly to cut off all the chains that bind me!" Gruba laughed and said, "I will definitely keep my promise and help you once when you need it!"

"Gruba!" Xu Feng laughed, "When I accepted this mission, I was still very weak. Your promise to help me was very important to me. But now, your promise is no longer valuable to me!"

Xu Feng stared at Gruba and spoke slowly.

"Gruba, if you want to escape, you need to think of a new reward, one that can attract me!"
