The Yin Qi barrier was thick and heavy, with a chilling aura that was completely condensed from Yin Qi. At the bottom of the side wall were soul-sucking vortexes, tirelessly absorbing the soul energy in the Soul Gathering Basin.
Above these vortexes and directly in front of us, there was a crack on the thick Yin Qi wall which emitted a faint light. This crack had been left by the Silver Armor Corpse King when it led its subordinates out through it. However, it did not seal up this crack after leaving.
We could use this passage to enter into the Yin Qi barrier. Without this crack, we would not have known how to get inside as anyone who entered into that thick Yin Qi wall would be torn apart instantly and absorbed by those soul-sucking vortexes.
Not only for us living beings but even for those Kings of Yins and Corpses; if they forcefully broke through this barrier, their fate would also be extremely tragic because this is considered as Wu Wang's tomb and Nine-Yin Yellow Springs' last line of defense which cannot be easily penetrated.
The gap was almost one zhang high above ground level so we needed to take a deep breath before entering.
"Teacher Xie, hold onto me tightly while I bring you inside. Jietou and Master Chi should take care of yourselves and follow me!"
After checking on the situation at hand regarding that gap, I quickly formulated an invasion plan.
However, just as we were about to jump towards that gap with all our mights; suddenly there was a dazzling light shining upon us making our shadows imprinted on the ground revealing an iron-black color.
Turning my head towards where that light came from; I realized it wasn't anything else but rather from that glowing pillar.
The Silver Armor Corpse King along with its subordinates surrounded themselves near that pillar not for leisure purposes but instead wanted to activate some kind of function on it.
Under their control, the pillar shone brightly, illuminating the entire underground world with a white light that made our eyes squint.
At first, we were shocked by this dazzling light but after a moment; when the Silver Armor Corpse King and its subordinates flew towards us, we finally realized something was wrong.
"The Heavenly Lamp Shines Upon Shadows! They have seen through our Sky-Covering Bell and discovered us!" I exclaimed in shock. Without much thought, I activated my Qi energy which caused the Sky-Covering Bell to fly up towards that crack on the Yin Qi barrier.
"Thief! Don't run away! Wu Zixu is here so why don't you come and die?" The Silver Armor Corpse King shouted loudly at us while flying towards us.
Wu Zixu?
Hearing what the Silver Armor Corpse King said made me feel surprised. I never expected that it would be Wu Zixu who was behind all of this.
You should know that Wu Zixu is a famous figure in history. He was not only an important minister of King Helü of Wu, but also a very powerful strategist and military leader. In order to seek revenge, he joined forces with Sun Wu's army to capture the capital city of Chu and whipped the body of King Ping of Chu after digging it out. These actions left a deep impression on the stage of the Spring and Autumn Period and Warring States.
However, according to historical records, Wu Zixu seemed to have committed suicide in the end. However, now it seems that there may be some undisclosed secrets behind this matter.
Wu Zixu may have indeed died, but he did not commit suicide. Instead, for some reason, he followed King Helü of Wu into the underworld and continued to serve him there.
He is now a four-stage corpse king with cultivation second only to King Helü of Wu. This shows that he is not idle here at Mount Modu but has gained access to abundant resources for cultivation. King Helü still values him highly.
A four-stage corpse king undergoes five hundred years per stage; thus two thousand years in total - his power cannot be underestimated or easily dealt with. Therefore, we must absolutely avoid being caught by him at this time; otherwise our mission will likely fail here directly.
"Quickly go up!"
Seeing that Wu Zixu was about to fly over towards us, I shouted angrily while holding Xie Yilin tightly as we leaped up straight towards the crack on top of the Yin Qi barrier.
Chen Qingshuai and Jietou reacted quickly too: when I jumped up they followed suit immediately so all four of us rushed into the crack together entering inside Yin Qi barrier.
Once inside Yin Qi barrier I immediately let go off Xie Yilin then drew Gan Jiang sword from its sheath and turned around to slash at the crack.
"Flames show mercy, sun's rays fierce!"
With a roar, I gritted my teeth and used Ling Tai Secret Art to concentrate all of my Lian Yang power onto the sword. Then both swords merged together into an extremely dazzling Lian Yang Qi Blade.
"How dare you thief-"
At the same time as the blade was swung out, Wu Zixu had just rushed outside of the crack. He watched helplessly as my Qi Blade hit hard on top of Yin Qi barrier.
"Boom - Bang -"
Under strong annihilation from Yin-Yang two energies, there was a violent explosion with smoke and dust everywhere; light and shadow were blinding. All four of us flew back more than ten meters due to that powerful impact force.
"YiHeng, what are you doing?"
Jietou flipped over and landed on his feet while looking at me puzzledly asking questions.
"This Yin Qi barrier is King Helü's last line of defense. Unless something unexpected happens this barrier can only be opened from inside. We now use Lian Yang power to disrupt its energy field direction which will seal off that crack so that Wu Zixu cannot come in anymore. Since he can't get in here anymore we'll have much less trouble ahead." Holding sword in hand watching as the crack disappeared from above Yin Qi barrier along with no trace left behind by Wu Zixu made me feel quite pleased knowing I had gambled correctly this time.
" How do you know that this barrier can only be opened from the inside?" Cheng Qingshuai asked with some doubt.
"It's simple, haven't you noticed? After Wu Zixu went out, he didn't close the crack channel. Why? It's for his return. Think about it, if this kind of crack channel can be opened from outside, why would they leave it open? They must have closed it directly after going out." I replied with a smile.
"Well said, Liu Yiheng. I didn't expect you to be so smart!" Xie Yilin's eyes shone as she looked at me with affection on her face.
I felt a little shy and quickly smiled and said: "No no, just average. Third in the world."
"Tsk," Jietou rolled his eyes and sneered upon hearing my words.
"Hush," while we were chatting and laughing, Cheng Qingshuai made a gesture to silence us before slowly turning around to look towards the center of the Yin Qi barrier.
Seeing his movement, we also turned our heads to look over there and were all surprised by what we saw - The legendary Wangling was actually like this!
