In the end, Yang Song did not even take anyone with him into the protective energy shield. Those people's stupid behavior was a good excuse for him not to bring them in.
The scene inside the protective energy shield was very similar to what Yang Song had imagined.
This was really a huge ancient battlefield.
In this place, the light was dim, like the legendary underworld.
And on the ground, there were densely packed corpses of various humans and monsters.
In addition, various elemental items fell on the ground here and there.
The temperature was a little bit cold and chilly. In this field, only silence filled the whole area.
"This ancient and terrifying aura portrays that the prosperity of the Middle Sky World in ancient times was probably not weaker than it is now."
In the Middle Sky World, the dispute between the human race and the Demon Clan had filled the entire history.
The fact that the two sides could stand in a stalemate for such a long time also fully proved that although the strength of the two sides was more or less on the same level.
The dispute between the two sides also prompted the continuous improvement and development of the cultivation way of the Demon Clan and the way of martial arts of the human race.
In the course of this development, both sides had left a mass of historical wealth.
This ancient battlefield was one of them.
With his super Spiritual Sense, Yang Song easily found the top most valuable relics on this ancient battlefield, all of which were very advanced elemental items.
Yang Song spent about half an hour picking up relics on this ancient battlefield.
After that, he set his eyes on a spot on the edge of the ruins.
That place was the source of the special water element energy on the protective energy shield.
At the same time, he asked Xue Ning, who was in the secret space, to come out.
"Miss Xue Ning, please feel carefully, is the familiar breath that you said earlier lies in it?"
Xue Ning's eyebrows frowned lightly, "It's exactly the same, it's really the same."
She said with some excitement, "It's this breath, the breath of the place where my sister is located is exactly the same as here. I even suspect that my sister is here."
Yang Song was very surprised when he heard this, and hurriedly asked, "Where is the breath in your mouth?"
"Both, both, I feel that all places here are full of that special breath, and," Xue Ning pointed to a direction and said, "that direction is particularly the strongest. I suspect that this special breath comes from that place."
Where was the direction Xue Ning was pointing?
Surprisingly, it was the source of the water elemental energy that Yang Song felt.
"Okay, I'm clear, Miss Xue Ning, you should hide in my secret space for the time being. After all, no one can tell what the situation is in that place. In case there is any unpredictable danger, I'm afraid I won't be able to take care of you."
Xue Ning nodded and then entered the secret space again.
"In this case, there is only one goal now."
That was the source of the energy of this special water element.
The scope of this ancient battlefield was very large, but for Yang Song, it was not a difficult task. After a few teleports, he came to the edge of the ancient battlefield, close to the protective shield.
This place could be said to be the most special on the ancient battlefield.
In addition to the special breath of the ancient battlefield itself and the energy of the water element, there was also a very restrained and rich atmosphere of space elements.
And the source of all these special breaths turned out to come from a stone stele without a word.
This stone monument was about ten meters high, and its surface was full of light that was unique to space elements.
"It seems that this is where they call the entrance to the minor realm."
For the sake of caution, Yang Song placed several Teleportation Formations on the spot, and then covered his body with several layers of protective talismans and skills.
Finally, he resolutely entered the stone stele.
This wordless stone tablet was actually equivalent to the entrance of a Teleportation Formation.
The whole process was the same as entering the Teleportation Formation.
But when this Teleportation Formation was only halfway through, the metamorphosis came into being.
There was a "door" of water elemental energy, blocking the way he was sent in.
"How can such an obstacle be placed between the two Teleportation Formations?"
Yang Song was stunned.
With his cultivation base and realm, it was impossible to guess the mystery in this.
How could this gate-shaped obstacle be bypassed?
He tried to use Profound Jump, but in this Teleportation Formation, space was blocked, and Profound Jump could not be used at all.
And even if it could be used, he estimated that after the use of Profound Jump, he might not be in this Teleportation Formation.
"Previously, Xue Ning said that only someone with the ability of the water element can save her sister, is it related to the water element?"
In the case of space blockade, Xue Ning in the secret space at this time had no way to come out.
Therefore, Yang Song could only guess that something related to the water element had to be used.
Fortunately, Yang Song was good at drawing talismans and he knew many talismans. Yang Song quickly took out an offensive water-attribute talisman called "Traversing Water Blade Talisman".
After the activation, the water blade shot and slashed fiercely on this energy gate.
The result turned out to be like dripping water into the sea, without a trace of waves.
"A failure?"
Yang Song guessed wrong, and the effect did not end there.
He saw that after his attack fell, there was a slight change on the energy gate.
This change was not obvious to the naked eye, but under Yang Song's Spiritual Sense's perception, it could be clearly found that the spiritual power on the energy gate had changed from being indestructible at the beginning to a kind of softness.
What did this mean?
When the changes on the light gate gradually subsided, he tried to touch it with his hand.
Unexpectedly, his hand passed through it smoothly. Correct, Yang Song's hand passed through the energy gate smoothly.
"Sure enough, it is related to the water element."
Upon seeing this, he stepped out one step, passing through the energy gate.
