Chapter 2234: Directly Upgrading to Grade 10 Secret Realm

That day, Xiao Feng was still contemplating the Di Jiang Battle Body when suddenly a special energy fluctuation surged and rippled out, enveloping the entire Mi Jing.

Little Tree Spirit successfully advanced!

Not far outside the house, the small tree floated in midair; the Dao Source Divine Tree had already completely disappeared, having been absorbed and merged.

A voice sounded in his sea of consciousness, and the Little Tree Spirit said: "Immortal Master, I have completed my breakthrough; now I feel wondrous!"

"Oh? How is it wondrous?" Xiao Feng asked curiously.

The Little Tree Spirit said: "After merging with the essence of the Dao Source Divine Tree, many memories have surfaced in my mind, as if left by the Establishing Tree of the Primeval Era; they contain many abilities that can make me very powerful!"

"That's great! What abilities do you have?" Xiao Feng continued to ask.

The Little Tree Spirit: "Many, like the effect of aiding cultivation; previously it was shaping spirit apertures, increasing spiritual energy density in the area. Now it's no longer so troublesome—I can directly build a city atop my canopy; within the city, every place has spiritual energy density not inferior to that of the previous Superior Spirit Aperture, capable of accommodating three thousand beings for cultivation, or ten Venerables."

"Moreover, I can separate seeds, just as the ancestor of the Establishing Tree separated me, by splitting off a portion of my essence to form a ninth‑grade Supreme Treasure Divine Tree or four sixth‑grade Supreme Treasure small trees."

"If my main body is injured, I can borrow life force from the flora and fauna of the myriad worlds to heal myself."

"If other beings are injured, I can also use my own life force to heal them."

In short, it has now fully inherited the abilities of the Establishing Tree; it is a miniature version of the Primeval Establishing Tree, and all its abilities are exactly the

"same, only slightly weaker than the Establishing Tree."

For example, building a city on the treetop: the Chaos City of the Primeval Era was immensely huge; accommodating millions of beings still felt cramped, and squeezing could fit a hundred million people, with over a hundred Venerables.

However, the merged small tree can only accommodate three thousand beings or ten Venerables at once, and its limit is still somewhat lower.

But for Xiao Feng, this is already more than enough!

After all, the previous Superior Spirit Aperture was only one, barely enough for his family members to reach the fastest cultivation speed.

But now, if we build a city, the numbers will surge, and all the experts in the region can fully enjoy the benefits of accelerated advancement!

"Little Tree, how big is your main body now? Can the Chaos Secret Realm contain you?" Xiao Feng asked a crucial question.

The Little Tree Spirit replied: "My main body is now several thousand kilometers tall, and with the canopy spread, it reaches over ten thousand kilometers—several dozen times larger than before. Immortal Master, I suggest you reshape the secret realm, taking the earth as its foundation, with me standing upon the earth and the city built upon my body; this way your people can obtain the best environmental enhancement effect."

Xiao Feng was dumbfounded upon hearing that.

A tree several thousand kilometers tall and over ten thousand kilometers wide!

This is too huge!

The previous World Ancient Tree was already huge, but its height was under 200 kilometers, its canopy spread about four to five hundred kilometers; only its root system was immensely large, enough to span the secret realm.

And now…

Simply terrifying!

"You said building a city on the canopy can only accommodate three thousand cultivators, so how can we move all the cities and players up there?" Xiao Feng asked it.

The Little Tree Spirit explained: "Immortal Master can treat the treetop city as a Superior Spirit Aperture, which is the best place. But at the same time,

the areas around me also have strong spiritual energy; cities built on the trunk and lower parts of the canopy are also quite good."

"I see." Xiao Feng realized.

A city for three thousand people is very small; accurately speaking, it should be called a palace.

For a canopy tens of thousands of kilometers wide, resembling a continent, that is merely an insignificant spot.

But the city can be large, accommodating millions, even tens of millions of residents.

"It seems the Chaos Secret Realm needs to expand; currently it is a grade‑5 large secret realm, which simply cannot accommodate your massive body."

The maximum diameter of a grade‑5 large secret realm is 5000 kilometers, still smaller than the canopy.

Even if upgraded to grade 10, with a diameter of 10000 kilometers, it would still be quite cramped.

Xiao Feng took out the treasure left by Di Jiang, the 【Space Source Heart】, and said to the Little Tree Spirit: "Try to see if you can absorb and merge it, to serve as the core of the Chaos Secret Realm."

The Little Tree Spirit received this mass of essence and examined it.

After a moment, it replied: "Immortal Master, this can fuse with me, and if separation is needed later, that is also possible."

The Space Source Heart is equivalent to an external resource that expands the size of a secret realm; when fused into a secret realm, that realm becomes much larger.

And when not needed, removing it returns the secret realm to its original size.

"Good, then I will first upgrade the secret realm to grade 10, then you will release your main body, after which we will proceed with the fusion!" Xiao Feng nodded.

Expanding the secret realm involves three steps.

Reaching grade 10 max is the first step, the Little Tree's growth is the second step, and finally comes the ultimate expansion.

As for how large it will ultimately be, Xiao Feng currently has no idea.

Xiao Feng opened the secret realm management

interface, and selected the 【Upgrade Secret Realm】 function.

Upgrading directly from grade 5 to grade 10 requires consuming 2880 Void Crystals, 288,000 God King Divinities, and 28.8 trillion God Stones.

Over the years, the war zone's overall gains have yielded plenty of Void Crystals; additionally, slaying the Sovereign of Stars and Di Jiang dropped some as high‑grade currency, and Xiao Feng has on hand several thousand, which is more than enough.

God King Divinity can be substituted with Venerable Hearts; the higher‑rank the Venerable, the more it offsets, at minimum a 1:10000 ratio, up to a maximum of 1:1,000,000.

He had slain many mighty warriors of the Wasteland Beast Clan, so it was naturally abundant; just picking a few ordinary Venerable Hearts would suffice.

The only thing lacking is God Stone.

28.8 trillion is no small number; even the treasury of the present‑day flourishing Chaos Divine Nation cannot produce that amount all at once.

Fortunately, the shortfall is not large; gathering some from the major guilds will be enough.

Xiao Feng spent some time gathering the resources.

That afternoon, the secret realm upgrade began.

【Ding~ Upgrade confirmed! All resources deducted!】

"Your personal cultivable secret realm "Chaos Secret Realm" will expand to grade 10; during construction, do not go to the realm's borders, otherwise accidents may occur."

"Regional announcement: the Chaos Secret Realm is undergoing upgrade; all teleportation arrays are temporarily closed; please all players stay in place and avoid large‑scale movement to prevent unnecessary trouble!"

The system popped up a few reminders, conveying Xiao Feng's message to the players in the five major cities of the secret realm.

「Can the Mi Jing still be upgraded? 」

「What's the situation? The Chaos Secret Realm is already so big, and it still wants to upgrade」

「？」

「What the hell does that mean, not letting us go? 」

「Damn it! Such a big matter, and they didn't even consult me; they completely didn't put me, Zhang Erdan, in their eyes! 」

Among the five major Chengshi, the players of the Blue Star 8th War Zone were all surprised; many who had been cultivating stopped now.
