The two of them walked along the black stone path to the gate of the ruins of the Holy City, there used to be a river around the Holy City, but now the river has long since dried up, and only the black riverbed remains. There is a 100-meter-long black stone arch bridge across the bridge, and three words are engraved on the bridge - Tongtian Bridge.

Zhang Chi looked at these three words and was distracted, what does Tongtianqiao have to do with Tongtianjing?

Qin Luzhu thought of a place with him, and whispered: "This Tongtian Bridge may be related to Tongtianjing." ”

Zhang Chi said: "Have you noticed that the three characters of Tongtianqiao are different from those on the stone tablet outside, this is a seal character, even I know it." ”

Qin Luzhu said: "What's so strange? Maybe it was built by later generations." ”

Zhang Chi was stunned for a moment: "You mean that the people from the Mystery Bureau built this bridge?"

Qin Luzhu said with a smile: "I really admire your imagination, anything can be linked to the Mystery Bureau." ”

Zhang Chi said: "I can't think about it, there are many people who know the existence of the Netherworld, and your grandfather still has ......."

Qin Luzhu said: "Do you suspect that my grandfather deliberately concealed the existence of the Netherworld Ruins for his own selfishness?"

Zhang Chi smiled: "How is it possible, I have always respected my master's character, besides, now he is not only your grandfather, but also my de facto grandfather, right?"

Qin Luzhu's face flushed, and he said: "Flim tongue, no shape, my grandfather is my grandfather, and your grandfather is your grandfather." ”

Zhang Chi thought to himself, this is true, I am not without a grandfather, my grandfather is to the sky, I can't tell you the truth about this.

Qin Luzhu said: "By the way, I suspect that the Netherworld Ancestor may also be a member of the Mystic Bureau. ”

Zhang Chi nodded: "I also suspect that he is one of the seven founders of the Mystic Bureau. ”

Qin Luzhu said, "Who do you suspect he is?"

Zhang Chi said: "It's not your grandfather anyway." ”

"Nonsense!"

Zhang Chi said with a hippie smile: "Using the elimination method, the most likely is to walk to the sky." ”

Qin Luzhu said: "I think so too. His eyes stared at Zhang Chi and said, "It turns out that you have thought of it a long time ago, no wonder you will say to him, I am your person, are you worried that he will not be good for me?"

Zhang Chi said: "Did I say so?" I originally thought that Qin Luzhu didn't pay attention to this matter, but I didn't expect her mind to be so meticulous.

Qin Luzhu nodded and said, "You naturally said it, and the Netherworld Ancestor seems to be very special to you, why did he choose to go with you? What is the relationship between you?"

Zhang Chi said: "Teacher Qin, you don't even believe me? What is the relationship between the two of us? I have handed it over to you, and you still don't believe me?"

Qin Luzhu chirped: "You are really shameless, I know what you think in your heart?

Zhang Chi said: "I don't understand why he is so good to me, probably because of my grandfather." ”

"Nonsense, the plan to deal with Xiang Tianxing and his wife is your grandfather's mastermind, and he hates your grandfather the most. ”

Zhang Chi couldn't help but laugh and said: "The person he hates the most should be your grandfather." ”

Qin Luzhu shook his head and said, "I heard my grandfather say that the person Xiang Tianxing hated the most in his life was Zhang Qingfeng. ”

Zhang Chi said: "It's not scientific, the eldest brother who took the lead in dealing with Xiang Tianxing back then was obviously Qin Lao, my grandfather was at most an accomplice, why did Xiang Tianxing hate my grandfather the most? ”

Qin Luzhu said: "He's the mastermind!" Stretched out his hand and patted Zhang Chi's shoulder and said, "Let's not guess, when we see the Netherworld Ancestor, you can ask him in person." She decided that the Netherworld Ancestor was walking towards the sky.

The two walked across the bridge to the gate of the holy city, saying that it was the gate, but now the gate is long gone, only the wall made of black boulders remains, Zhang Chi reached out and touched the black stone, his fingers were dyed black, he looked up and said: "There was a fire here." ”

Qin Luzhu said: "The battle of the Holy City. ”

"Who is fighting against whom in the battle of the Holy City, and since the battle of the Holy City did not involve the Netherworld, who was defending the Holy City before again?"

Qin Luzhu shook his head: "Maybe the mystery is in the city." ”

The Holy City is not large, square, one kilometer long and one kilometer wide, and most of the buildings were destroyed in the war, but the remaining stone structures still show the grandeur of the former buildings.

The two searched inside and out of the ruins of the Holy City, and did not find anything special, Zhang Chi felt a little disappointed, it seems that the Holy City has basically been destroyed, and the ruins that have survived have no special significance, he sat down to rest, Qin Luzhu still did not give up, and studied the statue text on the ruins alone, and recorded them one by one.

Zhang Chi looked around at this ruin, maybe it was just the same as human history, just a part of the history of the Netherworld civilization, some things were originally difficult to explain, for example, the civilization of the heavenly court has completely become a myth in today's society, the so-called holy city should also be the same truth, usually human beings will give mysterious characteristics to things they don't understand, the more they don't understand, the more mysterious they are, and in the end they become myths.

When Qin Luzhu was resting, Zhang Chi handed her the little dry food left, and Qin Luzhu said, "I'm not hungry, you can eat." ”

Zhang Chi smiled: "Look down on me, even if I don't eat now, there is no problem, there is abundant aura here, I can live a lifetime just by inhaling aura." ”

Qin Luzhu chuckled, "That's really easy to feed." Finding that Zhang Chi had cut a bunch of thick thorns, he had lit a bonfire, sat down beside Zhang Chi, took the scone cake handed to her by Zhang Chi and took a bite, although the ingredients were not very good, but after Zhang Chi carefully baked, the cake was baked crispy and crispy, Qin Luzhu praised: "Such a good craft, it's a pity that you don't do catering." ”

"I don't do catering, I do ......"

Zhang Daxianren's words were only half said before Qin Luzhu gagged his mouth with half a piece of cake, Qin Luzhu knew that his dog couldn't spit out ivory in his mouth.

Zhang Chi took a bite of the cake and took a sip of the boiling snow water: "Teacher Qin, have you found anything?"

Qin Luzhu shook his head and said, "The damage to the Holy City is too serious, and the information left behind is all fragmented, and it is difficult to piece it together, but give me a while, maybe I can find out some eyebrows." ”

Zhang Chi said: "With such a big place, it's not so easy to search them all, and there is not much time left for us." ”

Qin Luzhu knew what he meant, in two more days, the cold wave would recede, and the adventurers would come one after another, and they would not be able to investigate as freely as they did now. Qin Luzhu said: "Don't worry, there are still two days to go anyway." ”

Zhang Chi said: "Do you say that there will be a dungeon or something in this place, usually a dungeon of this scale is standard, maybe the treasures are hidden in the dungeon." ”

Qin Luzhu also thought about this possibility, but judging from her current investigation, she did not find the underground palace, she finished eating the half of the cake, took the kettle handed by Zhang Chi and drank a few sips of water: "Then let's go our separate ways, you go around to see if there is a underground palace." ”

"Not going to sleep?"

Qin Luzhu said: "What are you sleeping? Time is pressing, when they all come in, they won't be so comfortable." She got up and went on to investigate.

Zhang Chi finished eating half of the cake, yawned, and looked up, only to see that the smoke rose to about ten meters above to form a plane like water waves, and the light and shadow of this plane flickered. Zhang Chi has seen this phenomenon, it should be a light source passing from above, just projecting on the smoke, so it formed such a scene, got up to find the source of the light, and when he got up, the light and shadow above his head had disappeared.

Zhang Chi judged that the light should be coming from forty-five degrees in front of his right, so he walked along the direction, and after walking for a long time, he encountered a pile of ruins, and climbed the ruins along the ruins, but still did not find the direction of the light source.

Zhang Chi closed his eyes, screened away distracting thoughts, and felt the energy around him, many times, this perception ability was more sensitive than vision, and he could feel a cold aura seeping out from under the ruins.

Looking back at the direction of the bonfire, the scene just now appeared again, the strange thing is that I still didn't see the light shooting, the scene was fleeting, if according to the conventional judgment, the light should be projected straight from where he was, Zhang Chi didn't do anything, and directly lifted the stone pillar under his feet.

Qin Luzhu heard the movement and looked at Zhang Chi, not knowing what he had found.

Zhang Chi opened the two stone pillars one after another, and found that there were all broken stones underneath, and he wondered more and more in his heart, there was no light source below at all, but he could still feel the cold qi rising endlessly.

Qin Luzhu also climbed up along the ruins: "What's the situation?"

Zhang Chi told what he saw, and just at this time, the light and shadow above the bonfire reappeared, and Qin Luzhu also saw it, and exclaimed: "That light and shadow should be projected from here." ”

Zhang Chi said: "The strange thing is that there is no light at all. ”

Qin Luzhu looked up at the sky where the purple clouds were surging, and it didn't look like the light cast from above, the light and shadow appeared briefly and then disappeared.

Zhang Chi said: "There should be something strange down here, I can feel a kind of cold energy rising outward." ”

Qin Luzhu said: "I'm afraid the two of us alone won't be able to pick up so many ruins. ”

Zhang Chi said: "The underground palace should be below." ”

Qin Luzhu said, "Can you tell that the source of this energy is about a few meters deep?" If Zhang Chi can accurately locate it, she can try to arrange a teleportation array to teleport the two of them directly.

Zhang Chi said: "I have to think about this." ”

He closed his eyes and silently sensed the energy around him, according to what the Netherworld Ancestor said, everything in the world has its own energy, and the energy contained in it is different if the matter is different. If we can accurately assess the magnitude and intensity of the surrounding energy and perceive the source of each type of energy, then we can reduce the structure of matter backwards based on the energy.

Huang Chunli's scene reconstruction is actually based on this principle, Zhang Daxian has also made rapid progress in spiritual energy cultivation after receiving the guidance of the Netherworld Ancestor.

Qin Luzhu silently guarded him on the side, and from time to time he saw the light and shadow above the bonfire disappearing from time to time, and after about half an hour, Zhang Chi finally opened his eyes, and he was pleasantly surprised: "Twenty-three meters below, there is a hole in the ground." He got up and walked to a place about a meter to the left: "From here, if you open a straight passage, you can reach the bottom." ”

Qin Luzhu said: "I'll set up the formation." ”

Qin Luzhu completed the teleportation array in more than ten minutes, and the aura here was abundant, and even if the spiritual energy was lost, it could be replenished in time.

The teleportation distance of twenty-three meters is not far, but the construction of the teleportation array also requires certain conditions, and the openings of the portals on both sides are best open areas, which is the reason why Qin Luzhu asked Zhang Chi to locate as accurately as possible.

Zhang Chi had already had the experience of teleporting many times, and this kind of short-distance teleportation didn't feel anything at all, it was as simple as pushing open a door and walking from one room to another.

It was dark in front of them, and the two of them had already come to the cave that Zhang Chi said.

Qin Luzhu lit up the spirit stone lamp, and saw that the place where they were now was an arched Yongdao, the highest point was about two meters from the ground, and the width was about three meters, such a height made people feel a little oppressive, the temperature in the Yongdao was significantly higher than the outside world, I don't know where Zhang Chi's so-called cold energy came from? Although it is underground, the aura is still abundant, which makes Qin Luzhu feel a lot more at ease, which means that she can replenish the spiritual energy in time, and there will be no follow-up weakness.

Zhang Chi touched the stone wall on the side, his tentacles were warm, he also felt that the underground corridor was warmer than the above, but he still clearly felt a cold energy surging from inside, Zhang Chi said: "This should be the entrance to the underground palace." ”

Qin Luzhu said: "Go in and have a look." ”

The two walked inside, advanced more than 100 meters along the road, and saw two bronze doors appear in front of them, and above the copper doors were engraved two golden-armored warriors with angry eyes, which were exquisitely carved and lifelike.

Zhang Chi looked at the statue of the golden-armored warrior with some surprise, the appearance of these two people was extremely similar to the two security guards guarding the gate of the Lingxiao Palace, Zhang Daxian secretly wondered in his heart, could it be that this holy city is related to the Heavenly Court? This thought made his heart can't help but become heavy.

The two of them worked together, and the bronze gate slowly opened under their push, and a cold chill came out of it.

Qin Luzhu shuddered involuntarily, Zhang Chi didn't feel anything, it might have something to do with his psychological preparation.

Behind the bronze door is an ice cave, Qin Luzhu raised the spirit stone lamp to illuminate the surroundings, the scene in front of her made her stunned, but she saw that the stone wall of the ice cave was neatly arranged and sealed with baby corpses, and the strange scene startled her, and her left hand covered her lips.

Zhang Chi hugged her slender waist, signaling that she didn't need to be afraid, took the spirit stone lamp and took a closer look, and found that the babies who were frozen in the ice cave looked peaceful and lifelike.

Qin Luzhu said in a trembling voice, "Are they all dead?"

Zhang Chi said: "Maybe it's dead, maybe it can be resurrected." ”

Qin Luzhu said, "Why are they frozen in this place?"

Zhang Chi shook his head, according to the calculation of the Battle of the Holy City, if these babies had been hidden here before the Battle of the Holy City broke out, then it would have been more than a thousand years, perhaps because before the Holy City was breached, the residents of the Holy City froze these children here in order to avoid their children being slaughtered, and waited until there was a chance to recover them later.
