When Liang Feng washed the three pieces of the 'Fire Fighting Spirit Armor' and took out a glowing 'Xuan Ice Crystal' and prepared to put it on the 'Fire Fighting Spirit Armor', Ouyang Lanlan exclaimed with a painful look: "Seventh brother, don't wash it! We won't look for it tomorrow!"

After a pause, she said again: "We've been looking for so long, but we haven't even found the hair of the ancient sect, you ...... Why do you still have to waste so many sixth, seventh, and eighth level 'Xuan Ice Crystals'? Do you know how many spirit stones a piece of eighth-level 'Xuan Ice Crystal' like the one you have in your hand is worth?"

Liang Feng smiled and responded: "Find the last three stone mountains, and if we can't find them, we will go home!"

Of course, he knew that an eighth-level 'Xuanbing Crystal' could also be worth a small number of hundreds of millions of high-grade spirit stones, but at this point, according to the words in his memory in his previous life, the sunk cost was already very large, but he didn't want to give up, he wanted to add some more costs at the end to see if he could turn it over.

Ouyang Changxun looked depressed, and sighed lightly: "Changfeng, then you can search for the last three stone mountains, big brother, I can't lift my strength now." ”

"Good!" Liang Feng replied. He knew that Ouyang Changxun's original expectations were too high, so the current lack of success was a big blow to him.

"Perhaps, as long as you hold on a little longer, you can enter the harvest time!" he comforted himself in his heart, put away the four washed 'Fire Fighting Spirit Armor', and found a stone to sit on.

Looking at a white cloud in the blue sky with no focus, he began to think back to the situation of the twenty or so stone mountains he had searched before

Although no relics of the ancient sects have been found in the belly of these stone mountains, the situation in each stone mountain is still very different, for example, the giant cave in the No. 1 stone mountain is particularly huge, but only two simple stone chambers have been found on the cave wall; It is not deep, but there are dozens of stone chambers found on the stone walls, although these stone chambers are also empty, and there is also Stone Mountain No. 27, although the magma pool in the cave is not large, but it is hotter than the No. 1 Stone Mountain, which has a huge magma lake in the belly of the mountain.

"Why is Stone Mountain No. 7 so much shorter than Stone Mountain No. 1, but there are so many more stone chambers in it than Stone Mountain No. 1?, and why is the magma pool in Stone Mountain No. 27 the hottest?......?" he began to think about several questions that he had thought about many times before.

Previously, he had conceived a number of assumptions to answer these questions, and then he had adjusted his subsequent search targets based on those assumptions. Judging from the results of the current nothingness, his assumptions were either wrong, or his predecessors had guessed them, and they had already searched for all the treasures.

"Malegobi! It must be that his assumptions are wrong, and it is impossible for his predecessors to sift through all the ruins of such a large size, right?" He adjusted his sitting posture slightly, and secretly cursed in his heart that if the predecessors had really scavenged all the treasures in the ruins, then it would be impossible for monks of different eras to find the treasures of the ruins.

After sitting for a long time, Liang Feng had a flash of inspiration in his mind and asked, "Big brother, what legend do you say there is in this ruin?"

“...... What legend?" Ouyang Changxun looked at Liang Feng with dull eyes.

"When you first came, didn't you say what this ruin was' The Great Sage of the Netherworld entered the Human Realm with the Demon Pet 'Hell Demon Dragon' into the Human Realm ......', and then?" Liang Feng asked.

Ouyang Changxun was stunned for a moment, and responded, "Oh...... , that legend is that more than 100,000 years ago, an interface crack between the human world and the netherworld was broken by the ghost cultivators of the netherworld. So the great sage of the netherworld entered the human realm with the demon pet 'Hell Demon Dragon', and the 'Hell Demon Dragon' could attack from the depths of the magma, so this stone mountain was all traces left by the 'Hell Demon Dragon' when it launched an attack from the ground and its claws poked out of the ground. ......”

Liang Feng looked stunned, and the thoughts in his heart flashed violently: "...... If these stone mountains are really the traces left by the infernal dragon's claw attack, then his previous doubts can be explained very logically."

"Why is that No. 1 Stone Mountain the highest mountain and the least stone chamber inside?It should be because the original place is not important, so the defense is very weak, so the same Hell Demon Dragon claw attack, there is the most serious consequence of being destroyed. ”

"And the place of No. 7 Stone Mountain is obviously a more important place, so there are many stone chambers and the defense is relatively strong, so the consequences of being destroyed are not as obvious as No. 1 Stone Mountain!"

“...... If we follow the reasoning that "the less damage there is, the more important the place is, and the more likely it is that treasures will be found", then it should be in the small stone mountains or flat fields that the treasures are more likely to be found? But why is there no record of the discovery of treasures in the small stone mountains or flat fields in the classical books and notes?......

After thinking for a moment, his eyes flashed, and he secretly said in his heart: "The 'Hell Demon Dragon' is obviously a very powerful creature, its sharp blow obviously will not have the power of only a small mountain bag, and it is not a fool, it will not attack the barren and populated places, so the places it attacks should be important places, and it will inevitably leave behind towering stone mountains......"

It seemed that every question could find a logical answer, and Liang Feng's heart was full of excitement to solve the puzzle, and he took out the map of the ruins and spread it on the ground with a flip in his hand.

Leaning over and examining it carefully for a long time, his finger finally stopped on a red dot, and he shouted loudly: "Big brother, let's search this No. 67 stone mountain tomorrow, if we can't find anything at this target, we won't look for it!"

This No. 67 Stone Mountain was not the target of the search, but Liang Feng deduced from the starting point that 'the Stone Mountain is the trace left by the attack of the Hell Demon Dragon', and finally found that the No. 67 Stone Mountain was the most suitable for the 'central place'

This is because Stone Mountain No. 67 is neither high nor low, and there are three peaks one high and two low that are very close together, which shows that the Hell Demon Dragon attacked this place three times in a row at that time, and the three attacks did not form the highest stone mountain, which proves how strong the original defense of that place was.

Although Liang Feng looked excited, Ouyang Changxun still looked sluggish and replied lightly: "Okay, Changfeng, you just decide." ”

Rested for the night. On the second day, the three of them went to the sixty-seventh stone mountain.

Liang Feng made some preparations, and went down the cave alone, and the sixty-seventh stone mountain has three peaks, and there are three giant caves, and he is now going down to the first giant cave.
