Some old railways run through this tunnel, and they are paved with large and small stones, which are not very comfortable to step on. In the dim light, you can roughly see the path ahead, and the upper end of the tunnel is made of rocks, which have not been cleaned here for more than ten years, and the rock walls are covered with vines that look like creepers, making people feel like they are in a primitive cave.

"I remember that this creeper doesn't need light to grow? But it's dark here, it's so strange...... "There is a girl Nan Nan said. The vines were so dense that they didn't look like they were malnourished.

"Maybe you don't need this plant, you can find everything in nature." Tianyu replied.

"Well, that's true." The girl nodded, and although she still felt strange, it could only be explained in this way. There are many things in nature that cannot be explained, and people can only accept them. It's like today's arcane, almost a miracle, but the principle is difficult to trace. People can only use the heavens and stars born in the spiritual universe, but they don't know why they can produce such powerful energy, let alone why the spiritual universe corresponds to the real universe.

"Ah......h

"I'm sorry, I stepped on a fast stone, I thought it was a bone..."Xia Limo obviously had some heart palpitations, and then pointed to Tianyu's nose, with a look of indignation, "It's all your fault, what kind of story did you tell, it scared me to death..."

"Ahem, let's stir up the atmosphere." Tianyu smiled and explained.

The crowd breathed a sigh of relief and stared into the deep darkness that led to no apparent direction. Everyone wanted to hurry to the base, and after the survey, they should hurry out. There are two strongholds inside, one at a quarter and one at three-quarters, so that even if the demons gather because the equipment is turned on, you can escape by taking a quarter of the route at most. Although it is still a little longer, compared to surveying in the middle of the tunnel, the safety factor has improved much.

Even so, everyone's mentality is still extremely depressed, not only because the darkness blocks the view, but also because the construction of this tunnel cost money, and it is estimated that there is no high-level arcane that can not be opened, in this case, if there is a demon attack, there are only two roads to go before and after, there is really no way to go to the sky, and there is no way to enter the ground.

Influenced by Tianyu's lame ghost story, the girls always felt that there was something on the ground, and from time to time they looked at the ground, and their steps were a little messy.

Liu Feng touched his head, and suddenly thought of something, he should tell Wen Lu some ghost stories. I forgot, I was negligent. Liu Feng was about to walk towards Wen Lu's side, when he suddenly felt that someone had touched him, and he was wondering, when his dark pupils swept over there, only to see a thick vine stabbing towards him with teeth and claws.

Liu Feng's pupils shrank, and he scolded me secretly, and slammed out with a palm. The dark breath in the dark zone is particularly abundant, and the release of the shadow system is also extremely smooth, and the dark palm condenses almost instantly, firmly grasping the vine in his hand. Liu Feng's move seemed to alarm something, and there was a loud rumbling sound from the tunnel, and dust kept falling from the upper wall of the tunnel, which was sprinkled with enthusiasm, making everyone discouraged.

At this time, the others also noticed that something was wrong, Tianyu and Yu Ri no longer saved their magic energy, and raised the light to the extreme in an instant, only to see that everywhere they could see was green vines.

It turns out that this vine did not grow in the dark, but burrowed into this tunnel by itself!

The tunnel was still rumbling, and everyone didn't know what was going on.

"It's not going to collapse, is it?" Someone spoke anxiously.

"Probably not, rest assured, demon attacks were considered here, and the foundation of the building is particularly strong, so theoretically it won't collapse easily...... someone immediately spoke.

The group nodded, and the thick vines of this kung fu had already rushed over, constantly rushing left and right.

"Fight!" Shi Feixuan shouted violently, the sword qi and sword intent in her hand had condensed, and the sword intent river and the sea of sword qi turned into a surging river in an instant, and they slaughtered towards the thick vines. However, what made Shi Feixuan frown lightly was that this sword intent could not invade that vine, and even if the sword qi fell on that vine, it would be difficult to leave a trace.

Tianyu's golden robe was windless and automatic, the void projection descended, the golden nebula continued to move, and a round of dawn bloomed in the tunnel. As the light of the dawn spread into the depths of the tunnel, everything seemed like daylight under the light, and everyone could see more clearly, a thick vine of unknown length broke through, extremely fast, covered with terrible thorns, wanting to kill them here and turn them into their own nourishment!

Liu Feng's eyes showed a solemn expression, he still doesn't know what kind of demon it is, he is so uncomfortable before he has seen it, this demon is at least an advanced general-level demon, or the kind of demon that has few opponents in the same stage!

The vine that was held by the big hand of darkness struggled violently, Liu Feng couldn't control it a little, and the next second the vine seemed to break through, Liu Feng waved his hand, and one after another the dark restraints turned into a dark sword, and the dark sword was firmly nailed to the vine, and the vine was a little more honest.

Before he could catch his breath, more and more vines rushed in from the other side of the tunnel. The flames and demonic breath flowed in Liu Feng's eyes, and the black flame was born in an instant, constantly condensed to a high degree, and directly turned into a black flame flowing blade and slashed towards the vine, but as soon as the black flame flowing blade touched the vine, cracks were all over the blade, and then the black flame flowing blade, which was so strong that it could instantly kill the downstream generals, was directly shattered into several pieces, turning into demon breath and fire elements and escaping away. Liu Feng, who was manipulating the Black Flame Flow Blade, only felt that the vines seemed to be harder than reinforced concrete at the moment of collision!

"Hell, die!" Lu Bei's rock sword array condensed, and the rock sword followed one by one and blasted forward, but the vine directly shattered the rock sword, turning it into a piece of rock and soil, Lu Bei's sword qi and sword intent were not even as good as Shi Feixuan, just blocking it, and then the vine swayed and wanted to penetrate Lu Bei.

A bright bone shield bloomed in front of Lu Bei, but several vines kept slapping the shield, and it was shattered almost in a trance. Immediately after that, the shield was pierced by a thick vine, and it was a demon soldier who could resist the lower generals! Under the crisis of life and death, Lu Bei's face was pale, his body was weak, and he couldn't even think of escaping in front of this vine.

Just as the vines were about to penetrate the north of the land, a Dao Senran's cold ice power spread, and black ice blades burst out, constantly covering the vine with a layer of black frost.

"Let's go!" A burst of shouts rang out, and it was the dark ice of Yun Yehan. Taking advantage of the cold ice to seal the vines in Yunye, Lu Bei fled in a hurry and escaped.

On the other side, Tianyu's eyes were golden, and the flames around him were mighty, constantly circling and spreading around, and when they came up, they used the holy flame, but they kept burning the vines.

Several frost shields traversed the front of the vines, and there were even layers of water protection superimposed on them, hoping to resist the vines. However, as soon as the several vines swarmed up, the sharp hard thorns penetrated at once, and the sharp vine tails flashed with a terrifying cold light, directly penetrating through.

"Ahh

The vines were dyed blood-red, and only then did everyone see that there were dense terrifying barbs on the vines, which made people's scalps tingle.

More vines began to stab at the crowd. Everyone didn't have time to grieve, the starry sky projection all emerged, thunder and black flames intersected, constantly bombing, and there were shadows bound in the darkness shuttling, sealing the vines. However, the vine shook violently, and the nails made of the shadow restraint were quickly broken, and then the vine seemed to be enraged, and stabbed towards the group even more violently.

"Don't keep your hands at this time, or we'll all die!" One spoke.

Several people took out the life-saving demon soldiers, stopped fleeing, the demon soldiers in their hands flashed with dazzling brilliance, and all kinds of attacks violently bombarded the rear, black demon slashes, stabbing the ground, and there was a terrifying storm......

They are all from families, and everyone has some demon soldiers who are more or less beyond their own realm, and everyone no longer keeps them at this moment.

"Blazing aura!" Tianyu did the same, put away Jin Yan, took out the demon soldier, and punched out a ring that flashed with holy mangs, and it could be seen that the level of the demon soldier was very high, far surpassing the demon soldiers of others. A halo suddenly bloomed from the ring like a wave of water, releasing a terrifying coercion, the huge and terrifying divine sun slightly blocked the vine, and the terrifying ultra-high heat came out of the aura, making the vines a little afraid, and they didn't dare to step forward from a distance.

"Let's go, let's go..."The heat wave kept hitting his face, but Tianyu was pretending to be in a cold sweat, this demon soldier was given to him by his family to save his life, and the consumption of magic energy was inevitably too fast, and most of the magic energy flowed away in such a breath.

No one cares about the girl who died, and now it's a real life-and-death crisis! Liu Feng immediately arranged the four Black Flame Flow Blades in the rear, and then the Heavenly Wing Fire Feather condensed, and also fled towards the outside.

In fact, they didn't go deep into the tunnel, and the probability of escape was still very high!
