In order to prevent them from getting lost in the blood mist again, the two of them walked in the direction of the blood-red tree one after the other, after all, No. Seven's eyes could see clearly even in the blood mist.

Breaking away from the psychedelic illusion of blood mist, Qin Tian walked forward only to find that there were crisscrossing branches everywhere in front of him, and blood-red lines were clinging to it, and there seemed to be some thick liquid flowing slowly, like human blood vessels.

"It can't be the blood flowing from these branches, right?" Qin Tian leaned closer and took a closer look at the intertwined branches and said.

No. 7 purple mang's eyes slightly, through those blood-red lines to peek into it, those liquids he was also a little curious, there was no such thing in the lines on the blood-red trees when the blood mist did not appear before, this must have been brought by the blood mist when it hit.

The liquid flowing in the blood-red lines seems to be much thicker than the blood, and even many of them are stuck to the lines for a long time, and there are no impurities in the liquid at all, so it is too pure to say that the blood is too pure.

"I'm not sure, so don't get any closer." Seven said that he would stop looking at the branches, since he couldn't study them thoroughly, it would be better to ignore them, and save more trouble.

Qin Tian nodded, no matter whether or not there was blood flowing in this vein, it was impossible for them to spend time studying it now, and since it was caused by the blood mist, maybe they would disappear with the blood mist when it dissipated.

The two of them stretched out the branches and headed in the direction of the blood-red tree, if they wanted to solve the trouble in front of them, they still needed to find the root cause, Qin Tian guessed that there must be a way to crack the blood mist on the body of the blood-red tree.

Along the way, they didn't encounter any more blood arrows in the sky, and even the bloody aura in the blood mist was much lighter, maybe the guy in the shadows didn't want to spend any more useless effort to get this, just wait until Qin Tian and they walked in front of him before killing him.

After walking for about an hour, Qin Tian and the others finally walked in front of the body of the blood-red tree, and they couldn't help but feel a little shocked when they looked at the blood-red giant tree that had grown into three people tall.

I didn't expect the blood mist to be able to catalyze the growth of the blood-red tree to such an extent, if it was left unchecked, maybe this area would be completely covered under its trunk, and then it would not be spectacular, but as hellish and terrifying.

Qin Tian groped around the trunk of the tree, but the strange thing was that there was nothing that looked like a mechanism, could it be that this blood mist could not be recovered? And the strange thing is that he didn't even find the exit, this is definitely not the end of the cave, but where is the exit?

The search was fruitless, and when Qin Tian was about to take No. Seven to look elsewhere nearby, No. 7's right hand pointed directly at the center of the tree trunk, and a fine light flashed in his dark purple pupils, and he could see through the inside of the tree trunk at a glance, and also found something interesting.

"There is a secret passage in the trunk of the tree, which is connected to the underground blood river before, maybe it is the exit you are looking for, and the rest of the place is a thick rock wall, and there is no way." Seven groaned.

After hearing this, Qin Tian also stared at the trunk for a while, and after the dark light entered his eyes, he did find that there was some mystery in it, although the trunk was much thicker than before, but as the seventh said, there was really a secret passage leading to the front.

Could it be that this is the way to open the secret passage? Only by first removing the leaves used for suppression, and letting the blood mist contained in it breed the blood-red trees to grow wildly, will the hidden secret passages slowly reveal themselves.

Thinking of this, Qin Tian's heart throbbed violently, if it was really as he guessed, did someone in the depths of the cave want them to enter the depths of the cave? Even the bloody arrows no longer stopped them.

But no matter what, Qin Tian had to go in and find out, his grandfather had also been here back then, maybe he would leave some very important clues, and this was the only way to get out, they would definitely not be happy to die in this kind of place.

"Let's go, let's go in and have a look." Qin Tian raised his head and looked straight in the direction of the tree trunk, and the double hook jade mark on his chest also bloomed with its brilliance at this time, quietly waiting for Qin Tian's next move.

Seven nodded, he had wanted to get out of here for a long time anyway, the strange and eerie atmosphere here made him feel very uncomfortable, and maybe something strange would happen after staying for a long time.

Qin Tian's right hand turned into a fist, and the milky white light covered it, quickly hitting the trunk of the tree like lightning, and it was immediately retracted at the touch, leaving a wisp of dark energy hidden in it.

Immediately, a muffled sound came from the trunk of the tree, and immediately after, the trunk of the tree in front of Qin Tian and them slowly collapsed, revealing the secret passage that was so deep that there was no end in sight, setting off bursts of dust on the ground.

"Did you bring a flashlight?" Qin Tian looked at the secret path that was so dark that he couldn't see his fingers and asked No. 7 on the side, after all, his bag was lost in the black dragon's lair last time.

"No, I never go out with these heavy loads." Seven shook his head.

This can give Qin Tian a little headache, neither of them carries lighting equipment, this secret passage is pitch black, and they can't see anything, so the next road is not easy to walk.

Qin Tian and No. 7 slowly walked down the rock walls on both sides of the secret passage, and the blood mist around the blood-red giant tree was gradually sucked into it, and it also returned to its original size, even the secret passage that Qin Tian and the others walked disappeared at this time, as if it had never appeared.

At first, Qin Tian was a little worried that the secret passage would be too dark and there would be some unexpected things, but after entering, he found that both sides of the rock wall were inlaid with dark red balls like moonstones, although it was not very bright, but it was enough for Qin Tian and them.

But the seventh number one behind Qin Tian was in a somewhat abnormal state at this time, his face was pale, and large drops of sweat were flowing down his forehead, as if he was more nervous than when he was in the blood mist, but Qin Tian's attention was on the front of the secret passage and he didn't notice it.

Seven's uneasiness stemmed from the stone pendant hanging from his chest, which shone with a faint red light, and suddenly circulated a trace of dirty darkness, as if it had been born with it.

But the breath of the stone pendant has become no longer pure at this time, and a trace of evil is mixed in it, and even the eye ability that No. Seven has always been proud of cannot be used, and this situation is the first time that No. Seven has encountered it.

At this time, No. 7 also remembered what the boss had repeatedly warned him before leaving, the stone pendant was obtained from this cave, and carrying it into here again might cause some changes, could it be that this was the beginning of the change?

"Seven, be careful, something has changed!" Qin Tian suddenly shouted at Seven, and his whole body was also horizontal in front of Seven, as if he had noticed the abnormality in the secret passage.
