Chapter 821 4th Floor Underground Palace
The first underground palace is where the spiritual liquid pool is located.
This spiritual liquid is dozens of feet deep. If it is sealed and used sparingly, it can be used for fifty or sixty years.
Therefore, the first level of the underground palace is the energy core of the entire underground palace and is also the most important level.
The materials used in the underground palace were also directly sourced from local sources.
Now, after being bombarded by the six-colored divine thunder, the remaining ice has been shattered, and its solidity is much worse than before. It is just right for building a four-story underground palace.
It only took three days to complete the construction of the first floor of the underground palace, which was dozens of miles long, wide and hundreds of feet high.
The next step is to build the second level of the underground palace on top of the first level.
The first level of the underground palace laid a solid foundation, making it much easier to build the second level.
It only took one day to complete the construction of the second level of the underground palace.
The second level of the underground palace is mainly used for the cultivation of core monks, so thousands of caves were polished and built inside.
The construction of the third underground palace began.
This level of the underground palace is mainly used for the cross-domain treasure ship to absorb spiritual energy for recovery, so it appears quite empty.
After finishing the third level of the underground palace, the next step is the fourth level.
The fourth underground palace is located 500,000 feet underground.
The thick ice plays a huge role in isolating the chaotic forces outside.
This floor is the real underground mall, used to entertain visiting merchants.
It took less than 10 days to complete the construction of the huge underground palace.
It also contains various second- and third-order formations.
The concentration of spiritual energy also decreases from bottom to top.
The concentration of spiritual energy in the second underground palace is comparable to that of a fourth-grade low-grade spiritual vein.
The concentration of spiritual energy in the third level of the underground palace is comparable to that of a third-grade mid-quality spiritual vein.
The concentration of spiritual energy in the fourth underground palace is comparable to that of a second-grade superior spiritual vein.
Even the concentration of spiritual energy on the fourth floor exceeds that of most gas wells.
After discovering this gas well, the area within a radius of hundreds of thousands of miles can be included in the sphere of influence.
There are a lot of good things around here.
Just the rocky mountains 20,000 miles away from here have a vast amount of rocks available for mining.
The divine milk of creation extracted from the creation stone is so priceless that it can be said to be in short supply.
If you search carefully within hundreds of thousands of miles around, you will definitely find more good things.
Such a vast area cannot be taken care of by Beichen Cave Heaven and Xianmao Valley alone, so it can attract a large number of land diggers.
By then, this huge underground palace will become the commercial center of an area of hundreds of thousands of miles.
When he thought of this, Zhang Xuan became very excited.
Although the gas well was found.
However, everyone is now facing another problem.
Without the inter-domain treasure ship, everyone could neither go back nor move forward.
It can be said that apart from waiting here, everyone has no other choice.
"I have a fourth-level sound transmission talisman here, which can transmit sound a million miles away. Maybe it can help the cultivators over there think of a way to pick us up." Shen Dongzi said.
When Henry Zhang heard this, he was overjoyed and said, “That’s great. Why didn’t you bring out such a good thing earlier?”
"It's useless to take it out earlier. We only have this level of inter-domain treasure boat in Beichen Dongtian. Lower-level inter-domain treasure boats will be scrapped before they can travel 3 miles in this chaotic place."
Zhang Xuan thought of the Shenzhou that was being refined in Tianmo City, and he turned to look at Moke.
Mo Ke nodded and said, "When we came, the framework of Shenzhou had been basically built. According to the time calculation, Shenzhou should be able to be fully refined in another three months."
Zhang Xuan was overjoyed and said, "Okay, then send a message back and urge Tianmo City to hurry up and refine the Shenzhou. Once the Shenzhou is refined, come and pick us up immediately."
Shen Dongzi immediately took out his fourth-level sound transmission talisman and sent it back to Beichen Dongtian, briefly explaining the situation here and asking Beichen Dongtian's disciples to go to Tianmo City immediately to pass on the order of the ten clan elders.
After doing all this, everyone felt relieved.
We have to wait here for another three months.
Such a good environment for cultivation cannot be wasted.
Everyone went directly to the second floor of the underground palace, each of them picked a better cave and began to practice.
Zhang Xuan's Zhentian Sword has been nurtured in the Sword Valley for several days.
Now it's finally fixed a bit.
However, it will take a lot of time to fully repair it.
He activated the Nine Extreme Divine Meridians.
The Yang Meridian passes through the Sword Valley and comes to another interface world again.
In this interface world, a large amount of the original essence of the military path is overflowing.
However, the original essence of the military path that condensed into a long purple-gold river no longer exists.
Encountering that long purple-gold river is also a great opportunity.
If it weren't for that long purple-gold river, his Zhentian Sword would not have been able to successfully advance to a spiritual treasure.
The nine ancient treasures that he integrated into his body could not be upgraded to half-step spiritual treasures.
And all this was just the good fortune gained by the Yang Meridian's exploration of the purple-gold river for a breath.
At this moment, he began to feel curious about this desolate interface world.
I wonder where this interface world is?
How did it come about?
Why are there so many original essences of military power here?
There are too many puzzles, and I am afraid that I may not be able to find the answers in this lifetime.
At this moment, he used his Yang Meridian to continuously absorb the essence of the martial arts from this interface world.
These pure essences of the origin of military power continuously nourish the Zhentian Sword.
The speed of repairing the Zhentian Sword also increased.
A month later.
Zhang Xuan looked at the Zhentian Sword in his hand with joy.
This Zhentian Sword has been completely repaired.
At this time, the halo of Zhentian Sword was restrained, showing the unique charm of spiritual treasure.
With the Zhentian Sword in hand, even without the true energy to stimulate it, if he encounters a fourth-level sand spirit again, he will not be as embarrassed as last time.
Zhang Xuan put the Zhentian Sword back into the Sword Valley.
"The cultivation environment here is so good, why not make a concerted effort to reach the middle stage of the Nascent Soul?"
Zhang Xuan clenched his right hand tightly, looking confident.
After he obtained Wei Ruyan’s Yuan Yin last time, he was only half a step away from the middle stage of the Nascent Soul.
After this period of solid training, especially after opening up eight divine veins, he is now confident that he can break through to the middle stage of the Nascent Soul in this underground palace.
He practiced the Thunder and Fire Embracing Yuan Gong.
A large amount of fire-attributed spiritual energy gathered and continuously converged in his sea of qi.
Now, the Qiankun Tower that was integrated into his qi sea has reached the level of a half-step spiritual treasure.
This makes the spiritual energy in his sea of qi purer and more refined.
In the center of the Qi sea, a little Nascent Soul figure, with his eyes slightly closed, maintained the same posture as him, continuously absorbing the spiritual power in the Qi sea into his body, transforming it into fire-attributed true energy.
He took out the thunder-attributed spiritual object from the Half-Step Divine Treasure, absorbed the pure thunder-attributed spiritual energy inside, and poured it into his sea of qi.
The Yuanying figure absorbed these thunder-attribute spiritual powers and condensed them into thunder-attribute true essence.
The fire attribute true essence and the thunder attribute true essence continue to merge, condense and sublimate, turning into purple true essence.
With the presence of the Nascent Soul, the speed of refining true essence is dozens of times faster than that of the Golden Core period.
A month later.
Zhang Xuan's momentum suddenly increased.
His Nascent Soul figurine also grew a little bigger, with a full smile on its face in the center of its Qi Sea.
All the Half-Step Divine Thunder-attributed spiritual objects on his body have been used up.
Fortunately the outcome was good.
He successfully advanced to the middle stage of Nascent Soul.
