When Ye Li heard the sound of fighting, he was startled at first, and then the expression on his face became strange.
Judging from the location of the fighting sounds, the battle area should not be too far from here.
At this distance, if you use talismans or magic weapons to fight, there will definitely be spiritual light or spiritual fluctuations coming out.
With Ye Li's terrifying perception ability, it is absolutely impossible for him not to feel these movements, but Ye Li indeed did not feel the fluctuation of spiritual energy nor did he see the spiritual energy light in the darkness in the distance.
The only thing he could feel was the fluctuations of Yin spiritual energy.
Not far ahead, the Yin-type spiritual energy was fluctuating strongly, which Ye Li could feel.
Gu Yun, who was standing next to him, became excited the moment he heard the sound of fighting. He couldn't help but rush out from behind Ye Li and rushed towards the place where the fighting sound came from.
In his mind, the one fighting in the front must be his father Gu Tianwen.
When Ye Li saw Gu Yun rushing out, he could only hurry to follow.
"Brother Gu Yun, be careful, the situation ahead is a little weird!!!"
Ye Li said after catching up with Gu Yun.
Gu Yun was stunned when he heard this and asked, "What's so weird!?"
"Brother Gu Yun, didn't you notice that there were only sounds from the battle ahead, but no light or shadows were seen, and no spiritual energy fluctuations were felt?"
Ye Li said to Gu Yun.
Gu Yun was stunned when he heard this, then he finally reacted and said, "Yes, you are right, there is something strange ahead!!!"
As they talked, their pace slowed down. The traces of battle on the ground continued to extend forward, and not far ahead, in the huge space, there was an extremely dark place where the Yin-type spiritual energy gathered.
Ye Li and the others were only about ten meters away from this area. The light from their crystal lamps could not illuminate this area. The light sank into the darkness and disappeared.
Ye Li and Gu Yun both saw this strange area. Ye Li could even feel faint fluctuations of soul power from it.
"What...what is this!?"
Gu Yun said with a puzzled look on his face.
Ye Li said: "This should be a naturally formed formation. The Yin-type spiritual energy gathered here to form this huge formation, covering a large area.
These Yin-type spiritual energies have a strong corrosive ability, so when fighting in the black fog, the spiritual energy cannot penetrate at all and will be directly obscured by the thick Yin-type spiritual energy.
In this formation, I can still feel a faint soul power, and I don’t know what kind of power is inside this formation. "
Hearing Ye Li's words, the expression on Gu Yun's face became solemn. It seemed that the area in front of them was obviously not a good place.
"Brother Ye Li, what should we do now? If my father is really trapped in there, we have to go in anyway!"
Gu Yun said to Ye Li.
Ye Li nodded upon hearing this and said, "Yes, we really must go in, but Brother Gu Yun, you'd better stay beside me and don't be too far away from me.
I don’t know what special properties this formation has. If you are too far away from me, I am afraid that if something happens, I will not be able to protect you in time!"
Gu Yun also knew that the formation might not be that simple, so he nodded when he heard Ye Li's words.
The two of them stood outside the formation and observed it, and indeed they could not see any problems with the formation.
Ye Li even activated the Eye of Origin, but he could only see some simple but very consistent with the operation of the Way of Heaven spiritual energy trajectories running deep in the formation.
Ye Li didn't dare to attack the formation at will. After all, he was not clear about the specific situation of the formation. If Gu Tianwen was really in the formation, Ye Li's random attack on the formation might affect Gu Tianwen's safety.
Gently pulling Gu Yun's sleeve, Ye Li took the lead and walked into the formation in front of him, while Gu Yun just followed him in.
A strong yang force emanated from Ye Li's body and transformed into a shield of light that enveloped him and Gu Yun.
With the existence of Yang force, the surrounding Yin force will naturally have difficulty affecting them.
Of course, Ye Li did not dare to let the Yang power spread out. After all, he was just one person, and it was meaningless to compete with the Yin spiritual energy of the entire formation.
His Yang-type spiritual energy only needed to protect the area around the two of them, and there was no need to cover too large an area.
Ye Li, who had just entered the formation, immediately felt the power of soul in the formation. It was unknown what effect the combination of soul power and Yin power would have.
After taking a few steps, several black shadows suddenly rushed out from the dense Yin spiritual energy around them.
When the two of them looked closely, they found that the black shadows that rushed out were actually some spider-like creatures that were completely black and composed entirely of Yin spiritual energy.
These spiders are creatures born in the extremely rich Yin spiritual energy. They are not monsters, but they have the same attack capabilities as monsters.
However, the spiders in front of him were only at the divine level, and were not very powerful in Ye Li's opinion. Ye Li simply released the Yang Xing spiritual energy more violently, and could directly transform the Yang Xing spiritual energy into sharp arrows of light to pierce these spiders.
Ye Li's ability to control the power of Yang now is already very strong, and his secret method of body casting has also reached an extremely perfect state. He can control the spiritual energy around him with great ease.
Gu Yun looked at the attacks of the black spiders around him and felt a little panicked. In fact, he should not feel panicked under Ye Li's protection, but for some reason, since he just entered this formation area, he felt a surge of panic in his heart.
This strange feeling made him very uncomfortable, and he vaguely felt that Gu Yun's judgment ability was gradually weakening.
Neither Ye Li nor Gu Yun noticed this. The soul power, which was very thin for Ye Li, had a much greater impact on Gu Yun than he thought.
After clearing away the spiders around, Ye Li took Gu Yun towards the direction of the fighting sound.
As they continued to move forward, the sounds of fighting became louder and louder, and Ye Li and Gu Yun could vaguely hear human voices.
Listening carefully, they both heard someone cursing not far away. Ye Li could tell the curse sounded a bit old, and the moment Gu Yun heard the voice, the expression on his face suddenly changed.
"Dad, it's Dad!
He is still alive and he is right ahead!!!"
Gu Yun exclaimed as he rushed past Ye Li and ran towards the place where the sound came from not far away.
Ye Li didn't see that Gu Yun's eyes were filled with confusion. He looked panicked and had completely lost his judgment. (To be continued)
