The outside of the cave is covered with all kinds of weeds and vines, and it would be difficult to detect it if it weren't for the much higher temperature around the hole.

Lisabeth tugged at it for a while, and finally revealed the full view of the hole, which was not too big, but enough for one person to pass through.

The caterpillar also seemed to feel the heat wave gushing out of the hole, twisted its body and came out, and said to Gu Jiang and the others: "This is it, the temperature inside should be very suitable." ”

Ima Hong first flew into the cave entrance to check for a while, pointed to the unknown vines that grew outside the cave and hung down into the cave, and said: "With these vines, you can just climb into the cave, and the inside is not too high." ”

Gu Jiang and Murong Bai observed for a while, then looked at each other and nodded in unison.

After preparation and discussion, several people decided to leave Zhao Dahai to wait at the entrance of the cave, and the other four people went into the cave to investigate.

The temperature in the cave is much higher than outside, Gu Jiang and the fat girl both have fire spirit veins, while Luan Su is wearing a fire armor, which has a resistance effect to high temperatures, Murong Bai already has the cultivation of a spirit king, and he can also resist high temperatures.

Among the five people, only Zhao Dahai had poor heat resistance, so he was arranged to sentry at the entrance of the cave.

Not long after, Murong Bai and Gu Jiang had slowly slid into the cave along the vines, and while climbing, Gu Jiang also carefully checked the vines, which seemed to be thick but hollow, and he didn't know whether they were strong or not.

Fortunately, after a short time, several people finally fell into the interior of the mountain without danger.

The vines are about seven or eight meters long, and Ima Hong has already found out clearly, and after climbing to the end, there is a stone platform under her body to settle on, which is only three or five meters away, and she can easily jump down from the vines.

"Are you alright?"

Zhao Dahai shouted outside, Gu Jiang immediately responded, several people didn't have time to communicate with Zhao Dahai about anything, all their attention was attracted by the interior of this big mountain.

Looking down carefully, it turns out that the interior of this mountain is extremely wide, there are Qiankun inside, and in the middle of the position, you can vaguely see a stream of magma meandering out, circling a few times and then flowing into the stone wall on the low side, this kind of scene is by no means ordinary to see, it is magnificent.

The caterpillar poked its head out again and said to Gu Jiang: "Just take me to the vicinity of the magma, where the temperature is below, I should be able to upgrade quickly." ”

Murong Bai looked at his feet and said, "The temperature in the magma is extremely high, maybe there is a way to fuse the Five Spirit Xuanjing with the weapon and practice suddenly." ”

Since the targets were all at the magma site, the group began to walk downward, and the stone platform soon came to an end, and after a period of climbing, they found a naturally formed stone path, and finally descended to the vicinity of the magma in the middle of the mountain.

As soon as they got closer, they felt a wave of heat surging in, baking the faces of several people red, and Gu Jiang and the others immediately activated the spiritual power in their bodies to resist the increasing heat.

Finally came to the vicinity of the magma, and when he looked at it closely, it was like a sea of fire in front of him, extremely spectacular, Murong Bai walked in the front, slowly approached the edge of the magma, and began to try various methods of smelting weapons.

Naturally, he couldn't stay too long in such an environment, so Gu Jiang hurriedly released the caterpillar.

The caterpillar looked around for a while, nodded with satisfaction, and then said, "You wait, after I ascend in a while, I will blind your dog's eyes!"

After saying a cruel word, he ignored Gu Jiang and the others, and squirmed towards the rock at the edge of the magma.

When he got closer, he seemed to be covered by the red fire in the magma, and the caterpillar's entire body became almost transparent, and then he saw it wander around in place, spit out a few golden threads and wrap around the rock, hanging itself in the air.

The golden thread was as thin as a cow's hair, and it was difficult to catch it by sight if it were not for the light of the fire, and the caterpillar ignored the crowd, and began to spit out the golden thread around its body as if nothing had happened.

Gu Jiang raised silkworms when he was a child, and he was no stranger to this situation.

"That's true! If this continues, won't the caterpillar become a moth after a while, so that it can be promoted?"

Seeing that the caterpillar had formed a cocoon, Gu Jiang couldn't help but muttered to himself.

After a few moments, a golden cocoon had been woven, and it was hung on the rock with gold wire, only a meter or two away from the magma.

"Caterpillar, caterpillar, are you still there, can you hear me?"

Gu Jiang shouted a few times, but there was no response, and several people became dazed.

"What now?" asked the fat girl.

Gu Jiang didn't have any idea, and explained: "It is estimated that they will all turn into chrysalis, and they won't be able to hear the speech, so wait and see." ”

On the other side, Murong Bai pondered for a long time, but he didn't seem to find any effective way, he was sweating profusely, and he was still trying all kinds of things.

Unconsciously, an hour passed, Gu Jiang and the others were a little impatient, and seeing that the golden cocoon still didn't move at all, he walked forward with some curiosity.

The fat girl was also full of curiosity, followed behind Gu Jiang, and came to the edge of the magma.

"This cocoon is so big, Gu Jiang, do you think this looks like a mango?"

"Mangoes aren't so round. ”

"What about cantaloupe?"

Gu Jiang found that in the communication with the fat girl, he could only talk about food, even if he couldn't eat it, he had to forcibly talk about the taste.

As he was talking, there was a sudden stinging pain in his arm, Gu Jiang hurriedly withdrew his hand, it turned out that he inadvertently touched a silk thread hanging from the golden cocoon, and with just a little force, it actually drew a bloody mark on his arm.

"It's so sharp. ”

Curious, Gu Jiang carefully touched the golden wire again, and it was indeed quite sharp, but the tentacles felt extremely tough.

In his memory, such a sharp silk thread was used as a secret weapon, and it was extremely difficult to be detected after it was laid down, especially in the rush chase, once it was hit, it would be shattered and extremely bloody in the next moment.

Thinking of this, Gu Jiang was full of curiosity, wrapped his hands with clothes, and carefully pulled the silk thread, wanting to feel the specific degree of toughness.

It was much tougher than he had imagined, and after a little trying, he could clearly realize that although the silk thread was extremely thin, it was tougher than steel wire.

The force is increasing, but nothing changes.

"This thread is easy to get acquainted with. ”

Gu Jiang couldn't help but sigh in admiration, the fat girl was curious, and she also learned that Gu Jiang pulled a piece of silk thread in her hand, and pulled hard through her clothes for a while, obviously using more strength, but the silk thread was still the same, without any change.

"It's amazing. ”

The fat girl looked at her hands, her face full of surprise and curiosity.

"I'll try it with fire. ”

As she spoke, she activated her fire spiritual power, and there was already an extra flame in her hand.

"Eh, it's broken!".

Although the golden wire was tough, it roasted on the fire for a while, and in the blink of an eye, it had broken into two.

"I'll try again, it turns out this thing is afraid of fire. The fat girl burned the silk thread proudly, and seemed to be very interesting, with a sense of accomplishment on her face, and she didn't care at all, the golden cocoon had fallen into the magma.
