Yiluo Lie secretly took a breath of cold air, if Bai Yunfei really had the intention of harming himself, he would not be spared at such a distance.

Bai Yunfei threw the syringe on the ground and said softly: "Some utensils can feel the mystery in their hands, and whether there is a steel needle in this syringe can actually be weighed to know it." ”

Luo Lie nodded, at this time, the corpse began to melt, although Bai Yunfei also expected that the steel needle was poisonous, but he did not expect that after so many years, the toxicity still did not weaken, and it was so violent that it could actually melt the flesh and bones of the corpse.

After a while, the kung fu corpse had turned into a puddle of black liquid, in which shiny mercury could be seen, and a black cylinder was exposed, Bai Yunfei thought it was another syringe, but when he looked at it, it was different from the cylinder just now, it was obviously much smaller, and he was also very curious in his heart, so he picked out the cylinder. Put on gloves, first wipe the liquid on the surface with a cloth, and then twist it to see that it is just an ordinary wooden cylinder, unscrew the lid of the cylinder, and seal a roll of silk as thin as a cicada's wings.

Unfolded the silk scroll, but seeing rows of small characters embroidered with black thread on it, Luo Lie couldn't hold back the curiosity in his heart, and came to Bai Yunfei's side, but this silk scroll was embroidered with a secret for cultivating flying knives.

Luo Lie himself was an expert in the use of flying knives and hidden weapons, although he only had a cursory glance, he had already realized that this secret was profound and subtle. Although I had the heart to study it in detail, it was a pity that the secret was obtained by Bai Yunfei, after all, it was inconvenient to speak.

Bai Yunfei handed the silk roll to Luo Lie and said, "You can take it, it's useless for me to keep it." He was observant, and although Luo Lie concealed it well, the bright gaze that he had just seen the secret note flickering was still captured by him.

Luo Lie didn't politely take the silk roll with him, and said with a smile: "Then I'm welcome." ”

Bai Yunfei half-jokingly said: "There are many treasures in this underground palace, and the next time you meet what I want, don't rob me." ”

Luo Lie said with a smile: "A gentleman loves money and takes it in a good way, what Mr. Bai got first, I definitely won't rob it from you." ”

Bai Yunfei secretly scolded this kid for slippery, why didn't he say that the gentleman didn't win people's love? He was basically telling himself that the first come, first served, it seemed that the favor he gave him was in vain, and Luo Lie didn't appreciate it. Gazing at the corpse that had turned into a puddle of liquid, he found that the glittering mercury in the corpse had gathered together and then slowly flowed deeper into the cavern.

Luo Lie also noticed this situation, and initially thought that because of the topography, the mercury flowed from high to low, but if you look closely, the mercury flows into a groove the width of your thumb, and from the groove it quickly descends, forming a silver road sign under the illumination of the flashlight beam.

Luo Lie and Bai Yunfei both knew that mercury was poisonous, and if people were poisoned, they would have all kinds of hallucinations, for the sake of caution, both of them covered their mouths and noses, and followed the trajectory of mercury flow for twenty or thirty steps, and a huge stone carving head appeared in front of them, which should be the head of an ape man from the appearance, with angry eyes, and the mouth opened to the limit, revealing the fangs in the mouth, and the height between the upper and lower lips was about three meters, and there was a black hole in it.

The mouth of the cave was not closed, and mercury flowed straight into the ape-man's mouth from the middle of the tiny trench.

The two approached the entrance of the cave and illuminated the bottom with a flashlight at the same time, only to see that there was a vertical downward cave below, and the beam of the flashlight hit the bottom, which was reflected by the liquid surface as smooth as a mirror, and the whole cave suddenly became brighter.

The two of them involuntarily held their breath, and the liquid surface below was glowing with silver, and it turned out to be all mercury.

Bai Yunfei shook his head at Luo Lie, and his heart had already begun to retreat, although the two of them were not weak in martial arts, but the cave below was full of rich mercury vapor, if they inhaled excessive mercury vapor, it would inevitably cause damage to their bodies, Bai Yunfei had always been a person who cherished his feathers, and he did not come to return Mu Sanshou's favor to give Mu Sanshou his life.

Luo Lie observed through the beam of light for a while, and pointed down.

Bai Yunfei looked in the direction of his finger, and then noticed that there was a rudder-like mechanism on the wall on the west side of the cave, but the position was close to the mercury level, less than two meters away from the liquid level.

Luo Lie made a gesture and signaled that he wanted to go down.

Bai Yunfei secretly thought in his heart, knowing that there was a poisonous air below, Luo Lie still insisted on going, it seemed that the secret was under the surface of this mercury liquid, he nodded, feeling that there was already a little lack of oxygen, and retreated to the rear. Luo Lie also took a few steps back and came to a place where the air was relatively fresh, Bai Yunfei took a careful breath, but saw Luo Lie take out a gas mask from his equipment and put it on his head.

Bai Yunfei saw that Luo Lie was so well prepared, and he was even more sure that he knew the situation inside well before coming here, in fact, it was no wonder, after all, Luo Lie had already entered here before, in fact, Bai Yunfei did not expect that the reason why Luo Lie was familiar with the terrain was because he got the information of the underground palace from Lan Ximei.

Although Luo Lie could hold his breath for a long time, he didn't dare to take risks easily, and only after all his equipment was stopped did he fix the rope and prepare to descend.

Bai Yunfei secretly admired Luo Lie's courage, he must know that once Luo Hunt descends, his fate will be in his own hands, as long as he has the intention of harming him, Luo Lie will not have the slightest vitality, does he have so much confidence in himself? Sure that he will not harm him?

Luo Lie made an OK gesture to Bai Yunfei, Bai Yunfei helped check the fixing place of the rope, and the two just made eye contact, and Luo Lie slid down without hesitation.

Luo Lie couldn't tell whether Bai Yunfei was friend or foe now, but he could conclude that he didn't dare to act rashly before the thing Bai Yunfei wanted to seize appeared, not to mention the endless strange creatures that emerged underground, the intricate road alone would make people get lost, and he expected that Bai Yunfei would not dare to take such a big risk.

Bai Yunfei watched Luo Lie slowly climb down, and quickly judged that Luo Lie was deliberately killing time, Bai Yunfei could not guarantee to hold his breath for a long time, in this place where mercury vapor was everywhere, he did not dare to ventilate freely, so when he felt a lack of oxygen, he had to choose to return to the safety of the outside to breathe, and only after breathing did he dare to return to the front of this mercury cave to watch the progress, even if he was fast, it would take time to come back and forth, and what Luo Hunt did during this time was naturally out of his surveillance.

Arnold was choked by the smoke and coughed constantly, tears and snot all flowed out, and he couldn't see where Zhang Changgong was for a while, so he couldn't help but get nervous, and said in a low voice: "Brother Zhang." There seemed to be a hazy figure in front of him, Arnold wiped his tears while trying to look, his right hand quietly slipped to his waist to touch the dagger, his hand just touched the handle, the figure broke through the smoke and suddenly came to him, even though Arnold's eyes were blurred with tears, he still judged from the figure and movements of the other party that it could never be a longbow.

Before Arnold could pull out the dagger, a powerful cold palm choked his throat, it was the beast covered in scales, he picked up Arnold with one hand, Arnold's throat was choked, he didn't care to pull out the dagger, grabbed the opponent's wrist with both hands, kicked his feet in turn, trying to break out of the beast's control.

Arnold is burly and his strength is not weak, but he can't compete with the opponent with one hand with all his strength, as the opponent's palm becomes tighter and tighter, Arnold's strength also quickly exhausts, and the struggling movements become weaker and weaker.

When life and death hung by a thread, a burly figure pounced on the beast from behind, raised the feather arrow in his hand and stabbed the back of the beast's neck, and it was Zhang Longbow that appeared at the critical moment, Zhang Longbow only had the last feather arrow forged with Xuanjing, he didn't dare to use it easily, of course, his longbow had been broken by the beast, and now he could only hold the feather arrow and the beast for hand-to-hand combat.

Before the longbow could get close to him, the beast had already noticed, as if it had eyes in the back of its head, and grabbed Arno and threw it at the assailant behind him.

Zhang Longbow threw a mouse bogey, had to withdraw the feather arrow, trying to catch Arnold, but could not buffer the power of Arnold's rapid flight, and was hit by Arnold's body, and the two rolled together and fell to the ground, both of them crashed into each other.

Arnold said in a low voice: "Hurry up...... "It is better for one person to die than for two people to die, and in front of the beast with strong combat strength, the two of them together are not opponents.

Although Zhang Changgong also understands this truth, he will never abandon his companions, and even if the man's husband dies, he must be upright.

Looking at the approaching beast, Arnold hurriedly touched the dagger, only to find that the dagger had been lost in the fight just now.

Zhang Longbow raised his pistol and fired a shot at the beast, the bullet hit the beast's chest with a snatching sound, and the beast's body staggered slightly due to the impact of the bullet, but the bullet obviously could not successfully repel him.

Zhang Longbow fired a second shot, but this time it broke the arrow, inserted the tip of the arrowhead forged from earth crystal, and used the thrust of the bullet to push the tip out.

The beast was super alert to Earth Xuanjing, and in the face of the bullets, he suddenly leaned back to the right at this moment, and the tip of the arrow glowing blue was against his chest, and Zhang Longbow's carefully planned killing move failed again.

Arnold struggled to stand up, he pulled open his shirt, revealing the explosives tied to his body, and yelled: "Damn!

The beast was actually frightened by his momentum, and stood there hesitantly not daring to move forward.

Arnold lit the fuse on his chest without hesitation.

The beast was not fearless, and he stared at the rapidly burning fuse on Arnold's chest, quickly made up his mind, turned and fled to the rear.

Zhang Longbow is also hot-blooded, death is as light as a feather, some are as heavy as Mount Tai, and it is not a pity to die with his best friend, Arnold is not afraid of death, he is naturally not afraid of death, and he is a good man after eighteen years. Zhang Longbow thought that it would be blown to pieces and annihilated, but he didn't expect that the fuse lit by Arnold did not detonate the explosives. The creature threw a lit fuse on the ground, and it was only the fuse that was lit.
