"Yes!" After the voice of the sycamore giant tree sounded again, Pu Zitong nodded, pulled Zhang Su behind him with his hand, and while leading Zhang Su's soul to the ghost tomb, he replied to the sycamore giant tree, and in the blink of an eye, he passed through the curtain of soul power, and his soul probed into the inside of the tree.

After entering the tree, what caught Zhang Su's eye was not the trunk of the giant tree, but a pitch-black space with a wide field of vision, there was no grass or wood around the space, and there was no existence like those strange sycamores in the Sycamore Forest, the only thing that there was a stone all over the ground, the shape of these stones was extremely weird, like a thorny tortoise shell covering the earth, and the color on it was crystal green tendon color, but it was somewhat similar to the color of the soul crystal stone that Zhang Su had seen, and he felt the essence of the soul power in it, Zhang Su guessed, Those weird stones should be the ghostly crystals mentioned by the giant tree Sycamore earlier.

"Is this the ghost tomb? Although you can see the boundaries of the space inside this tree with your soul eye, it seems to be extremely wide, about the size of a football field or two, right? In the ghost tomb space, Zhang Zhen was afraid that Pu Zitong was worried that he would covet these crystals in front of him, so he did not continue to focus on those strange stones, but followed behind Pu Zitong, looked around with his soul eye again, and asked Pu Zitong.

"No, to be exact, there's only a millimeter of space here." Pu Zitong was also looking around, not ecstatic about those weird soul power crystals, but as if he was looking for something else.

"A 'millimeter'? How big is that? Zhang Su hadn't heard of the unit of measurement used by Pu Zitong, but he always felt that it was a very small measurement, and asked with a frown.

"A 'millimeter' is a 'millimeter', which is a measurement used by the ancients, in a sense, it is the smallest volume of life, you can understand it as the size of a cell, although it is not completely accurate, but it is also approximate." Pu Zitong answered Zhang Su's question, and continued to use his soul eye to look around the situation in the ghost tomb, as if he felt that Zhang Su's question was a little unintelligent.

"The size of a cell? Are you kidding me? The souls of both of us are more than a meter tall, but they seem so small here, you say that there is only one cell in this place? Are you kidding? Zhang Su knew his height number, so he was stunned for a moment by Pu Zitong's answer, and asked with a puzzled face.

"I didn't tease you, it's not how big it is, but now we are smaller than a cell, when we passed through the curtain of soul power just now, the prohibition on it has made your soul 'essence', that is to say, your soul has been reduced as a whole under the same soul power, but you don't notice it." Pu Zitong seemed to think that Zhang Su was making a fuss, and explained disdainfully.

"The ban has shrunk our souls? Is there still such a means? That's too perverted, isn't it? Hearing that his soul had been shrunk, Zhang Su quickly checked his soul body, and after seeing that there was no problem, he asked in surprise.

"This is one of the laws that my ancestor comprehended after he advanced to the Soul Immortal

force, of course, to be able to do this is the result of my ancestor's unremitting efforts, and now you will not understand ...... you have told this, the ghost spar here is roughly equivalent to the level of the high-grade soul spar and the high-quality soul spar, and it has an excellent effect on replenishing soul power, and its essence can be directly assimilated with soul power, I won't stop you if you want, but you have to do me a favor before collecting these ghost spars, if I succeed, I will give you half of the ghost spars here, how about it? Hearing Zhang Su's surprised question, Pu Zitong shook her head helplessly, but she didn't want to explain the problem of the ghost tomb space to Zhang Su here, but instead changed the topic and made a request to Zhang Su.

"Are you willing to take me into this kind of place, there must be some help for me to help, give me half of the ghost crystals? Well...... well, if you have any commands, just ask. Zhang Su could feel how refined and rich the soul power in those ghost crystals was, and when he heard Pu Zitong say that he wanted to give half of himself, he was really a little moved, nodded, and directly agreed.

"Okay, then I'll say it straight, the door of the ancient tomb has been opened, although there is a powerful soul guard of the ancestor of my family, but it is also possible that some passing soul masters and ghost ghosts will find that the soul power here fluctuates, so we can't stay here for a long time, in a limited time, I want to look for a silver hairpin in this vast space, you have to help me find it, no matter which of us finds it first, I will share half of the ghost crystals in this ghost tomb space, but if you don't find it, you are not allowed to touch these crystals, If you dare to forcibly touch it, I will leave this space directly, and let the tomb guards outside block this space again and trap you in it, do you understand? Seeing that Zhang Su agreed, Pu Zitong was still a little relieved, and threatened Zhang Su again.

"What do you think I am...... aren't you just looking for a silver hairpin? Although I don't know what it is, I'll just help you find it, but since it's a silver hairpin, it should be regarded as a real thing in the world, and even if I find it, how can you and I take that thing out with a soul stance? Zhang Su knew that Pu Zitong was not at ease with him, so he pursed his lips and snorted softly, and after speaking, he asked Pu Zitong again.

"You don't have to worry about this, since I came in to look for that silver hairpin, naturally there is a way to take it out, just call me directly after you find it, the sooner you find it, the sooner you can absorb the ghost spar here, so you have to work hard." Seeing that Zhang Su didn't seem to have any dissent, Pu Zitong was a little relieved, and smiled at Zhang Ji and said.

"Are you sure there's the silver hairpin here?" Seeing that Pu Zitong laughed again, Zhang Su was a little suspicious and asked.

"Well, at least according to my great-grandfather's family letters, when he conquered a thousand ghosts, there was a ghost who had just broken through to the first level of the ghost king and was also banned and suppressed by him, he was afraid that the ghost king's soul would have some abnormalities, so he added a powerful horcrux to the ghost king to suppress it, that is, the silver hairpin, that is, the thing I was looking for, and it has not been opened here for so many years

Enlightened, the silver hairpin should still be in this ghost tomb, but where is the specific location, my ancestor didn't say, so I can only find it little by little. Pu Zitong explained.

"It should be a Horcrux, well, as long as it's a soul, I have some means of searching, and voila, I'll help you find it soon." After listening to Pu Zitong's explanation, Zhang Su probably knew what the silver hairpin was, his eyes rolled in a ghostly manner, and then he squinted at Pu Zitong and patted his chest to reassure.

"Okay, limited to the center of this soul curtain, I'll search to the left, you search to the right, if you find it, just call me, don't touch that thing at will, be careful that the energy in it will hurt you." Seeing that Zhang Su showed a confident look, Pu Zitong nodded, and finally reminded Zhang Su, as soon as he finished reminding, he turned around and walked to the left side of the space, avoiding those thorny ghost crystals, his soul eyes flashed with blue light, and he carefully searched for the ground.

Zhang Su saw that Pu Zitong searched carefully, he did not immediately look in the opposite direction to Pu Zitong, but stood in place, his eyes looking at the ceiling of the ghost tomb space, as if he was thinking about something.

"Silver hairpin......, the ...... of the Horcruxes, can suppress the ...... of the Ghost King, it should be an extremely powerful forbidden Horcrux, this kind of Horcrux should have a huge soul power, in this space, how can this Horcrux be nameless, but from the moment I came in, I didn't notice that there was any powerful and strange soul power, not to mention that these ghost crystals were blocked by a special soul power scab outside, so why didn't the Silver Hairpin Horcrux release a powerful soul power? Could it be that he exhausted his soul power when suppressing the ghost king? It is possible that ......, of course, there is another possibility, that is, the silver hairpin horcrux is covered by something to cover the emission of soul power, if this is the case, then the silver hairpin may be in a ghost crystal, well, probably start looking for it from these two clues. Pu Zitong had already searched a few meters, but Zhang Su pondered and analyzed in his heart, after analysis, he came up with two possibilities, with these two guesses, Zhang Su's eyes lit up, and he began to search towards the area to the right of the ghost tomb.

Zhang Su and Pu Zitong's exploration methods are not the same, Pu Zitong just uses the soul eye to observe every inch of space he passes, while Zhang Su uses the soul eye to observe those ghost crystals, and at the same time uses the means of the stele soul tuo to explore the traces of the ghosts more than 100 years ago, trying to find out the location of the ancestor of the Pu family who suppressed the ghost king, but because of the many ghost scars, and because of the evolution of the years, many traces have slowly faded, Zhang Su actually did not get any useful clues from those traces, I can only carefully investigate step by step, and I dare not have negligence or omission.

After searching for about ten minutes, Pu Zitong still lowered his head like an old farmer and patrolled, and Zhang Su also stretched out his hand to continue groping on the ground and ghost crystals he passed, but neither of them seemed to have gained anything, and they all had a sad face.

"It's not a way to go on like this, if it's really as Pu Zitong said, the opening of this ghost tomb will be detected by the soul master or the ghost

,Then this place really can't stay for a long time.,If I don't find the silver hairpin quickly,I may not have time to absorb the essence soul power in these ghost crystals here.,Well......,Think about it.,Where will the silver hairpin be in this ghost tomb? It's just that it's a waste of time to look blindly like this, if I were the ancestor of the Pu family, I would suppress the ghost king somewhere in this ghost tomb, thinking that after the ghost king disappeared, the silver hairpin must have landed near the spar that the ghost king had turned into......" Seeing that he couldn't find it, Zhang Su stopped again, muttered to himself, and analyzed the possible location of the silver hairpin again.
