With this hint of light yellow, Chen Lei felt that the Qiankun Qi in his body seemed to have roots. The Qiankun Qi used to be extremely ethereal and light, but this time it felt somewhat solid.
Chen Lei tried to use the Qiankun Yiqi Sword. A faint yellow aura was also contained in the sword light. However, it was this faint yellow aura that increased the power of the sword technique many times.
In the past, the sword light of the Qiankun Yiqi Sword was incredibly fast, but its power was relatively weak. However, now a sword light is both fast and heavy, and its power has become extremely terrifying.
Chen Lei was extremely surprised by this harvest. He was sure that this kind of mysterious and yellow energy was absolutely hard to come by and was more precious and rare than any magical herbs and medicines.
In the next few days, Chen Lei still stayed in this cave to practice.
A few days later, a layer of mysterious yellow energy rose again in the cave.
And this layer of mysterious yellow energy was also absorbed and refined by Chen Lei.
In this way, Chen Lei stayed here for three months. During these three months, Chen Lei figured out the pattern of the appearance of the mysterious yellow energy here.
The mysterious yellow energy here appears once every half a month.
During these three months, Chen Lei absorbed and refined the Xuanhuang Qi six times.
After absorbing and refining the Xuanhuang Qi six times, the light yellow color of the Qiankun Qi in Chen Lei's body became darker.
However, the power of Qiankun Qi has increased several times.
At this moment, the universe was in harmony, and there was a hint of the charm of the skills passed down by the First Heavenly Emperor from the upper realm.
On this day, Chen Lei was practicing, when suddenly, the earth shook and the whole cave was shaking.
Chen Lei's divine sense spread out and he discovered that outside the cave, there was a ferocious rhinoceros beast as big as a hill, attacking the nest.
This ferocious rhinoceros beast is also incredibly powerful, with the strength of an early stage powerful being.
Chen Lei could even feel that this rhinoceros beast might be able to break through to the middle stage of great power at any time.
In the past, this place belonged to the territory of the earth dragon beast, so naturally no ferocious beast would break in.
However, up to now, the Earth Dragon Beast has been dead for nearly four months, and the aura left by the Earth Dragon Beast has long since dissipated.
This area can be called a no-man's land.
Such an ownerless land will naturally attract new ferocious beasts to appear.
This ferocious rhinoceros beast came here under such circumstances.
This ferocious rhinoceros beast likes to eat the god-deceiving grass the most.
Near the nest of the earth dragon beast, there were many such god-deceiving grasses. This rhinoceros beast ate all of them in the past few days.
After eating, the rhinoceros beast naturally discovered the nest left by the earth dragon beast.
Afterwards, the rhinoceros beast began to attack the nest, trying to destroy it.
This ferocious rhinoceros beast intends to stay here and occupy this territory, so he wants to completely destroy this nest and eliminate all traces left by the earth dragon beast.
