The place Liu Yuan said was the huge inscription on the top that they had never studied, and Professor Gao and they just wanted to find out where the tomb was, and the dark river whirlpool just attracted their attention, plus those two huge ancient characters, it was not something special, and the difficulty of reaching the top also made them ignore it, and now listening to Liu Yuan, it is indeed somewhat possible.

In fact, for Liu Yuan, lettering is not an uncommon thing, anyone with some eyesight will only feel majestic, but will not associate it with the entrance, because it is indeed too ordinary except for those few sketches, but Zhang Erhe has found something on the lettering, which has to make him have some ideas.

"So what's there to look for, who would build the gate in that place? Don't talk nonsense, boy. Wang Juliang choked coldly and scoffed at Liu Yuan's speculation.

"Shut up! Xiao Wang, I asked you to find out those two words earlier, how did you check them? Professor Gao's tone became colder, and his gaze at Wang Juliang became slightly cold, the lettering can be said to be the most critical clue in addition to the vortex, he was delayed because of the vortex rushing out of the bones, so he handed over the task of exploration to him, but now that he hears it, Wang Juliang has never been there at all.

"Teacher, I..." Wang Juliang spoke a little hesitantly, and he didn't dare to look at Professor Gao, his eyes slanted at Liu Yuan, his gaze was not good.

"Alright, inform all the staff, be sure to report everything there to me tonight, without delay!" Professor Gao's words were a little cold, and listening to Wang Juliang's ears, the taste was mixed.

"Teacher, now..."

"Immediately! Right away! Wang Juliang wanted to say more, but was stopped by Professor Gao, and he didn't dare to say another half a word.

All the staff were on guard, and even some people who had just fallen asleep were woken up, in addition to these, Professor Gao also sent people to the rear cave to call people, and with them alone, the archaeologists were still too slow.

"Seven, I'll leave it to you here, you two come with me!" Telling the matter, Professor Gao pointed at Liu Yuan and the others, his expression was quite solemn, as if he had made a major decision, and walked towards the place where the tent was supported without looking back.

"Senior, what are you?" Liu Yuan had some guesses in his heart, and there was a little more brilliance in his eyes when he looked at Professor Gao, and Zhang Erhe was much simpler, where Liu Yuan went, where he went, this was already the only thought in his heart at present.

Professor Gao didn't look back, sighed, as if talking to himself, and said, "There are some things that I still need to let you know about, it's me who is selfish, alas! ”

Liu Yuan chuckled, it seems that Professor Gao did have something to hide from them before, thinking that this matter must not be simple, otherwise he would not have let them know until now.

Back in the tent, the three of them stood together, while Professor Gao struggled, shook his head slightly, and still groped inside the tent.

"What is this?" Just for a while, there was an extra fist-sized bead in Professor Gao's hand, with dense patterns, and the material should be a metal ball like bronze, with tight indentations, like a rattan ball, just at a glance, Liu Yuan couldn't take his eyes off, and the strange aura that vaguely emanated from it was very familiar.

"In fact, this thing is our most important discovery, I have studied antiquities for so many years, and it is the first time I have seen such a magical copper ball, the beads stand in the water but do not sink, and the water meets the beads but does not stick, this kind of thing that violates the principles of heaven is beyond our ability to speculate." Professor Gao sighed with emotion, looking at the copper ball, stunned for a while.

"Senior, can you let me take a look?"

Professor Gao nodded, handed over the copper ball, and when he started his hand, it was quite heavy and almost landed.

"Good guys!" Liu Yuan couldn't help but exclaim, his hands made a slight effort, only to set the copper ball in his hand, the pattern is distributed in the form of irregular circles, graceful and enchanting, such as the Nine Heavens Fairy Catching the Moon, the lines are smart, even Liu Yuan can't help but be moved, the essence of craftsmanship, rare in the world, and in addition to these, every line, there is a layer of tight smooth texture wrapping, greasy and not stained at all, and on the copper ball, the simple atmosphere is gracefully floating, and the years have not eroded, this phenomenon can't help but make Liu Yuan think of the huge fish bone he saw in the mine before.

"Uncle Zhang, take a look." Liu Yuan threw the copper ball over as he spoke, but Zhang Erhe almost didn't follow, which caused Professor Gao to be dissatisfied for a while, and he looked pity, and Liu Yuan had no choice but to be helpless.

"Senior, have you found anything else besides this thing?" Liu Yuan asked, seeing that Professor Gao shook his head slightly, it was inconvenient to continue.

"To put it bluntly, at present, we only have a clue of the copper ball, but after data analysis, this copper ball is just a general bronze material, I think for so many years, it has not been eroded, it should be related to the layer of wax oil on it." Professor Gao said this, looking at Liu Yuan with some expectation.

"I think so too, senior, where did you find this ball?" The only clue must be traced to the source.

"On the maelstrom!"

Under the lettering wall, a group of people are busy, very noisy, and on the side of the whirlpool of the dark river, only three people stand quietly, looking at the strange scene in front of them, stunned speechless, the copper ball is gently thrown into the vortex, the original circulation of the suction force dissipates instantly, in exchange for the vortex is in the middle, the copper ball flows slowly in the air, does not rise or fall, quite magical, and with the copper ball into the vortex, the original cleansing of the galloping sound, seems to be much smaller, wait for a while, there is no more white bone eruption, even the vortex, not as turbulent as before.

"Yuan'er, this thing should be a key." Just as Professor Gao and Liu Yuan were thinking, Zhang Erhe's cold words made them all tremble in unison.

"Keys?" Liu Yuan turned his head in surprise and looked at Zhang Erhe incredulously, it seemed that after coming here, Zhang Erhe seemed to have changed as if he had changed a person, not only was he silent, but even his senses were much stronger than Liu Yuan, which was strange.

"Possibly, senior, did you find anything else after you went down from the vortex?" Liu Yuan said, picked up a piece of white bone from the ground at random, sniffed on it, and threw it into the vortex, as expected, as soon as it entered the water, the white bone sank, and the copper ball was still dripping and rotating, unaffected.

Professor Gao thought about it, but still shook his head, as if there was something unspeakable, and finally sighed and said, "Didn't the two of you find anything different from this copper ball?" ”

Liu Yuan was stunned for a moment, and glanced at Zhang Erhe, what did Professor Gao mean by this?

"Alas, I used to have a friend who was a Taoist priest, and he told me that in ancient times, human beings had a strange ability, which could change some of its states by applying it to utensils, I wonder if you have heard of this ability?" Professor Gao said slowly, this ability Liu Yuan naturally knows better than anyone else, but why did Professor Gao suddenly mention this? Liu Yuan has always avoided talking about this, but when Professor Gao said it, he still felt a little uncomfortable.

"I've heard of it, it should be a kind of magical power, you mean this thing has been tricked?" Liu Yuan asked rhetorically.

"It should be, after all, this thing is too strange to explain it with my skills." Everything must be based on facts, which is something that archaeologists must follow, and Professor Gao's words made Liu Yuan extremely uncomfortable.

"Okay, I'll study this copper ball again." Time is pressing, they can't spend all of it on this, and use long objects to get the copper ball back, but Liu Yuan didn't follow Professor Gao, found a vacant land, and sat opposite Zhang Erhe, but Professor Gao returned to the tent alone and didn't say anything.

After being silent for a while, Liu Yuan's face was bitter, he pursed his lips, and looked at Zhang Erhe pitifully, "Uncle Zhang, to jump or not to jump?" ”

Liu Yuan was naturally referring to the vortex that continued to rotate in front of him, in fact, the two had long guessed that if they wanted to find something in this underground rift, it was completely impossible to find anything else except within this vortex, but Professor Gao's rhetoric was very unreliable, and under the vortex was another underground dark river, but they would rather stay here for a long time than explore deeply, which was a contradiction in itself, and they didn't find anything in a month? Who to bluff?

"What can I do if I don't jump? Jump! The corners of Zhang Erhe's mouth twitched, deliberately splitting all the others, but now he was suffering the two of them.

"Jump!"
