It has been decades since Old Man Song discovered this place, and it took him a lot of hard work to break down the layers of natural mechanisms. Naturally, he didn’t want others to take advantage of him who worked so hard. Every time he left, he would set up a lot of formations here, for fear of someone breaking inside.

In the past, Old Man Song even used formations to cover up the entrance of this cave, but it took a lot of magic weapons to set up formations outside the cave, and every time a formation was destroyed, it was equivalent to digging out his heart. Later, more and more formations were broken in the cave, so he abandoned the formations outside the cave and used all the magic tools in the cave.

Old Man Song walked into the front and dismantled the formations he had set up one by one. Although he felt that Jiang Wei could not understand these, he still cautiously let his two apprentices follow behind him to block Jiang Wei’s sight.

Jiang Wei didn’t care about Old Man Song’s defense at all. This kind of formation was a treasure in the eyes of Old Man Song. If it was his little master who came, she might not even give him a look while breaking through these formations. What’s more, if he wants to see, he doesn’t necessarily have to use his eyes, his spiritual sense was easy to use.

Old Man Song’s formations defend against both outsiders and himself. Although he knew what formations were deployed and where the eyes of the formations were, it still took some effort to break through these formations. Jiang Wei stopped and walked behind. The more they get inside, the more time they spent time. In the end, Jiang Wei couldn’t help but look for a comfortable place to sleep first.

The cave has many twists and turns. Old Man Song spent a lot of thought here. He took out several thin and thick books. Whenever Old Man Song didn’t know which way to choose at a complicated fork in the road, or when he forgot the steps when breaking the formation, he would pick out one of them and search. Jiang Wei felt tired just looking at him.

After staying in the cave for another two or three days, Jiang Wei had almost eaten up all the food in his backpack, and the group finally reached the end of the cave.

“Jiang’er, come here!” Old Man Song stretched out his hand to call Jiang Wei with malicious intentions, pointed to the mountain wall in front of him, and said, “I need your help next.”

Jiang Wei reached out and touched the wall, then turned to Old Man Song and asked, “Is this also a formation? Have you understood it after researching it? Don’t waste my blood in vain.”

Old Man Song let out a sinister laugh: “Don’t worry, I cherish your blood as much as you do. After all, it took me a lot of effort to find you, and I don’t have time to find the next person.”

“I’m relieved when you say that.” Jiang Wei took off the empty backpack on his body and threw it on the ground, and took off the thick down jacket that the fifth apprentice lent him, revealing the casual clothes inside.

Jiang Wei moved his limbs and shook his neck: “Okay, I’m ready, what do you think should be done?”

Old Man Song was very satisfied with Jiang Wei’s understanding of current affairs. He took out a box from his arms, opened layer after layer, and finally revealed a dark red stone.

Old Man Song held the box carefully, with a fire-like light in his eyes: “I got this stone by breaking through this formation, and I think it is the key to unlocking the next formation.” Old Man Song looked at Jiang Wei, the voice became extraordinarily long, and it seemed to have a hypnotic effect: “Now you need to place this stone in the recessed place on the stone wall, and then fill the gap with blood, and the formation will be broken.”

“It sounds very simple!” Jiang Wei curled his lips: “Why do I feel that it is too easy compared to the formation you broke earlier, are you sure you are doing it right?”

Old Man Song smiled lightly and said nothing, it sounds uncomplicated, but in fact, this level was the most difficult. Not to mention how difficult it was to find blood, there were so many people in the world, how to tell whose blood was useful or not? It was also because of his luck that he accidentally got a treasure-hunting gold bug not long after leaving here.

Old Man Song felt very proud when he thought of this matter, even if God helped him so everything was possible.

Seeing Old Man Song laughing more and more complacently, Jiang Wei no longer looked at him but lowered his head to study the stone in his hand. This stone was as big as his two fists combined and looked a bit like a human heart. Although it is substantial in his hand, he always feels like something was wrapped in it, and this thing seems to be very close to him as if it was connected with his blood.

Perhaps it was because Jiang Wei was too focused on studying the stone, Old Man Song was a little uneasy, and urged him repeatedly: “Don’t delay the time, put the stone on it quickly.”

According to what he said, Jiang Wei placed the stone in a recessed place in the mountain wall. It was strange to say that the hole was not deep, but the stone was very stable after it was placed, and it didn’t fall at all.

Jiang Wei touched the stone and the mountain wall. There was a gap about the thickness of a finger between them, a lot of blood must be needed to fill it. Old Man Song waited by the side. But at this time, he had drawn out a sharp knife and looked at Jiang Wei very vigilantly. If not for fear of wasting blood, he would have done it for him.

“You cut yourself, cut deeper.” Old Man Song licked his dry lips, with a greedy look in his eyes.

Jiang Wei took the knife and only made a shallow cut on his finger. It seemed that just after a layer of skin was broken, a few drops of blood came out. Old Man Song became anxious when he saw it. Just as he was about to speak, he saw that Jiang Wei had already put his finger on the stone, and the dragon energy in his body rushed out with a trace of blood mist, filling the gap in an instant.

At this moment, the heart-shaped piece that was put in suddenly vibrated, and pieces of broken stones waved down from above, revealing a glowing red heart-like thing, instantly sucking up the blood mist in the gap net.

Feeling the strong dragon energy emanating from the heart, Jiang Wei knew what it was without guessing. Now he turned around and wanted to run out, but his body seemed to be frozen, and he couldn’t even move.

Old Man Song’s eyes lit up when he saw it. He was both annoyed and regretful. Although he didn’t dare to guess what it was, he knew it was a good thing just by looking at such a powerful breath. He should have Jiang Wei as soon as he catches him. He shouldn’t have delayed until this time.
