There is metal inside the black zircon, which is extremely hard. Even if he points it with the Yanyang Finger and uses multiple fingers in succession, wasting a lot of real energy, he can only explode a few feet square, but cannot explode the entire piece of black zircon.
Lu Chen released his soul power and inspected the surroundings of the entire cellar.
It was found that the black zircon layer above and below the cellar was very thick, several miles long, and thousands of feet thick in the front and rear direction.
The left side is the weakest, with the black zircon layer only ten feet thick. Unfortunately, that side is the exit, and there are countless guards waiting to kill him.
The only place where you can use your brain is on the right side. The black zircon layer there is about 500 feet. If you have enough strength, you may be able to find a way out.
Lu Chen used Zhantian and slashed at the wall on the right.
The power of Zhantian is so powerful, but it only cuts through a layer of black zircon that is one foot square, and the power is far from enough.
To break through the entire black zircon layer on the right side, at least five hundred cuts would be required!
Five hundred swords can be used to cut, but the problem is that after the cut, Lu Chen's physical energy and true energy have been mostly consumed, and he needs to recover before he can cut again.
The Spiritual Essence Liquid and the Three-Line Spiritual Qi Pill are limited, let alone five hundred swords, even fifty swords cannot support them.
The only way now is to break through to the fourth level of Yuan Dan Realm!
The basic strength of the third level of Yuan Dan realm is not enough, only 30 million kilograms of strength.
And the basic strength of the fourth level of Yuan Dan Realm is 60 million kilograms!
The basic strength is fully doubled, and the power of cutting the sky is increased even more.
If you practice the second sword of slashing the sky, it will be more powerful and more powerful than the first sword.
Lu Chen looked at the Chaos Orb and saw that the vein core, carrying the remaining spiritual energy, was moving little by little towards the new spiritual energy vein. It seemed that he wanted to take possession of this new spiritual energy vein.
Lu Chen stretched out his hand, reached into the Chaos Bead, gave the pulse core a hand, and pushed it to the edge of the new spiritual energy vein.
In the blink of an eye, the pulse core took the original spiritual energy and merged into the new spiritual energy vein.
Not long after, the pulse core sent Lu Chen news that it had occupied the new spiritual energy vein, and Lu Chen could enjoy it at any time.
Lu Chen then grabbed out the new spiritual energy vein, then sat down cross-legged, running the Nine Dragons Return to Duel, frantically extracting the rich spiritual energy from the new spiritual energy vein.
The reason why Lu Chen took out the spiritual energy veins instead of letting the flame dragon veins enter the chaos beads was because the two dragon veins worked together and were much faster and more efficient than one dragon vein.
The danger Lu Chen faces now is, will the Lord of Demon City come back before he breaks through?
The Demon City Lord is a powerful Tiangang Realm expert and the strongest demon in Demon City. If the Demon City Lord comes back in time, it will be a disaster. No matter what, Lu Chen can't defeat the Demon City Lord now.
An hour passed, and the only sounds outside the door were the guards yelling and cursing, and the Lord of the Demon City had not yet returned.
And the large amounts of spiritual energy extracted from the double dragon veins are all converted into streams of true energy, enriching the Chaos Pearl.
It has to be said that this larger spiritual energy vein contains a lot of spiritual energy and is very pure, allowing Lu Chen to obtain more true energy faster.
Another six hours have passed, and the mysterious iron gate still hasn't opened, and the Lord of Demon City still hasn't returned.
However, the new spiritual energy vein has been thinned by a small circle, and the Chaos Bead has already been filled with true energy and compressed to the limit.
Bang!
There was an explosion from within the Chaos Bead.
The real energy that had been compressed to the extreme rebounded and instantly opened the Chaos Bead, doubling its size, making the space of the Chaos Bead reach 600 feet square.
The Chaos Bead replaced Dantian, and Lu Chen broke through and crossed a huge gap.
Fourth level of Yuan Dan realm!
Lu Chen did not stop his efforts and continued to extract the spiritual energy from his spiritual energy veins to consolidate his new realm.
Another hour passed, and Lu Chen's violent aura gradually calmed down, and his realm was finally consolidated.
Lu Chen then stopped his work, retracted his spiritual energy veins, took out the Xiaguang knife, and prepared to test the knife.
With his current strength, with the increase of the twin dragon veins, his own strength is as high as 180 million kilograms.
The first sword that cuts the sky can be used at any time, and its power reaches its maximum.
With one slash, the black zircon layer was cut open three feet on the spot. As expected, after breaking through to the fourth level of the Yuan Dan realm, the power of cutting the sky became much stronger.
After one blow, physical energy and real energy are not consumed much, and there is still some energy left!
Lu Chen continued to slash, slashing with multiple knives in succession before his physical energy and true energy were exhausted.
I drank a drop of Spirit Soul Essence Liquid and took several thousand three-line spiritual energy pills before I recovered.
And the black zircon layer only cut out less than twenty feet, which is still far away from five hundred feet.
Limited to the support of the Spiritual Essence Liquid and the Three-Line Spiritual Qi Pill, the first sword to cut through the sky would not be able to create a way out.
Lu Chen gathered his mind, silently recited the formula for the second sword to cut the sky, and slowly circulated the mental method of the second sword to kill the sky, allowing the true energy of the Chaos Pearl to quickly travel through the specific route of the second sword to the sky, and finally injected it into the blade.
"Zhantian, second sword!"
With one slash of the knife, the space was shattered, and the force of the knife whipped up a torrential wave of air that impacted the entire cellar.
All the sunworms were immediately killed by the air wave, and the walls of the cellar were shaken by the impact of the air wave, causing the pavilions on the top to sway unsteadily and even affecting the entire city lord's palace.
boom!
The blade fell and the ground shook.
The force of the knife was so strong that it directly chopped the black zircon layer into pieces by hundreds of feet!
The second slash to the sky was so powerful that it was beyond imagination, but it drained away all of Lu Chen's physical energy and true energy.
Lu Chen stood with his sword in place, his face turned pale and his body was shaky, as if he had returned to the time when he was at a low level and used his first sword to kill the sky.
Zhan Tian is really...
It’s so powerful!
After drinking the spirit essence liquid and taking the three-line spiritual energy pill, Lu Chen quickly recovered, and then...
Keep cutting!
After five consecutive cuts, all the black zircon layers on the right side were broken through, and finally we saw mud and soil.
Lu Chen relied on the power of cutting the sky to cut a way out!
When the earth rune chain with the secret of escape from the earth lands on him, Lu Chen can escape from the earth and walk away.
However, after walking about three hundred feet in the blasted black zircon layer, Lu Chen discovered a cave three feet square.
This cave was completely covered by the black zircon layer, because Lu Chen struck this side and shook the cave out. Otherwise, no one would know that there is such a cave in this black zircon layer.
This cave is very unusual. There is a terrifying energy flowing out, blocking any soul exploration.
There is someone in the cave!
Moreover, he is also a person with extremely terrifying cultivation!
Lu Chen thought for a moment and walked in decisively. If he didn't go in and take a look, how would he know what was inside?
This cave is buried deep in this layer of black zircon and will never see the light of day. Even if there are people, they will be dead long ago.
What if the dead person leaves behind something treasure?
Then just send it!
If you don't go deep into the tiger's den, how can you catch the tiger's cubs?
As soon as he entered the cave, the terrifying qi force became even more intense, making Lu Chen breathless. Even if he released his majestic soul power, he could only resist half of the pressure of the qi force, and Lu Chen would still have to bear the other half of the pressure.
In addition to the Qi machine, there was also a simple and desolate breath blowing towards his face, as if telling Lu Chen that he had been silent for millions of years.
