In the next few minutes, Ye Yuxuan and the three of them explored six wrong forks in the road, four of which were dead ends, and the other two were interconnected, this structure reminded Ye Yuxuan of tunnels used for defense and preservation of living forces, and the design here should be based on the same principle.

Later, they encountered more than five magic devices in these forks, including pipes for ventilation through runic elemental magic, appliances for heating by using runes to control the flow of heat, and instruments for water purification based on water elemental rune magic. The principles of these things seem so unscientific that any normal person who sees them will instinctively doubt their authenticity because they violate the well-known laws of science.

However, they really existed like this, and they were functioning normally in front of the eyes of the three of them, and this was enough to open the eyes of Ye Zi and Su Mu, who had not been in contact with this aspect of things.

Especially Ye Yuxuan, he felt that when he approached those runes engraved with elemental magic, he would have a unique sense of intimacy; This feeling is very weak, and Ye Yuxuan himself can't tell where this feeling comes from, but it really exists like this.

In addition, they also found some alchemy products that looked beautiful at the end of these four dead ends, but were actually residues and waste products, including but not limited to iron pieces with ultra-high hardness and ultra-high density - Ye Yuxuan picked it up and checked it, just the size of a palm weighed dozens of kilograms, almost superconducting, but it itself belonged to a metal rod of super permanent magnets, shaped like crystal, extremely clear and transparent, but it would begin to decompose on its own when it saw light - when Su Mu dug this thing out of the moundHe thought he had dug up a crystal vein, but as a result, this thing only existed in his hands for less than half a minute...... To put it bluntly, it's all useless garbage.

Yui Uesugi put a piece of impermeable fabric back into the pile of garbage with a blank face, if any physicist came here, he would definitely be mad on the spot, after all, water molecules are larger than gas molecules, as long as the hole is open small enough, it is completely possible to be breathable and impermeable, but what kind of trouble is this impermeable and impermeable? But this kind of thing that violates common sense, those strange wizards did it like this, although it ...... Their creators themselves don't seem to like these creations very much.

"Is the defective rate of this alchemy so high?" Ye Yuxuan looked at the mountains of defective products beside him, and couldn't help but ask.

"It's not so much that there is a high rate of defects, but that alchemy itself is a matter of chance." Yui Uesugi rolled her eyes halfway through speaking, "In low-level alchemy, the caster can only determine a general direction of transformation, but cannot decide the method of achieving it and the price it needs to pay. Like the previous piece of iron, the best example of this is that simply compressing an object to increase its strength and the consequent weight problem is clearly not what the wizard originally wanted to see. ”

Ten minutes later, the trio who had been shuttling between the dead end and the garbage heap for a long time finally made a new, valuable discovery in a deeper place.

After taking all the wrong paths, the group of three finally walked into the correct passage, and when they were halfway through, a five-meter-wide isolation door completely blocked the way forward.

The gate was about three meters high, glowing with a pale golden metallic sheen, and the thickness was unknown, but judging by the specifications of this thing, it should not be less than half a meter. The material that makes up the main body of the gate is also very hard, Ye Yuxuan picked up the knife pinned to his waist, which is generally used to open the bulletproof package of rations, and slashed the surface of the gate, but he failed to leave a single scratch. You know, this knife is made of titanium alloy doped with tantalum carbide and niobium carbide!

The scene near the gate is also completely different from other places, and the passage that the three of them walked through before has largely retained its original appearance, except for the occasional artificial traces and man-made objects such as magic lanterns used for lighting. Within ten meters of this gate, it has almost completely been replaced by a man-made building, and the ground in front of the door is covered with dense square stone bricks, creating a wide flat land large enough to accommodate four lanes on the originally uneven cave landscape; Slightly curved, jade-like wall tiles surround the surrounding cave walls, forming a semi-cylindrical ceiling, which looks like a warehouse for parking aircraft. The light from the top of the cave wall and the magic guide lighting at the top of the gate illuminates the vast space in front of the gate, and the exaggerated lighting that is completely inconsistent with the alloy gate that should be rustic and atmospheric, makes it seem as if it is no longer a separate door in a cave, but a magnificent palace entrance.

In addition, Ye Yuxuan and the others were unable to find any other possible magic guidance equipment nearby, and the thick alloy gate in front of them had neither a lock hole nor any authentication equipment, just like a turtle with a shrunken head, making people unable to start.

After tossing and turning to no avail, Ye Yuxuan finally decided to use a little technical means to open this door.

"Yezi, are you really going to do this? This will use up all the explosives we have left, and if we can't break it, we'll be all wasted. After listening to Ye Yuxuan's plan, Su Mu immediately realized that the feasibility of this plan was not high.

Facing the doubts of his good friends, Ye Zi just smiled slightly, and while counting the dozen or so 20mm grenades neatly arranged on the ground, he replied: "If you can't pass through this gate, it's a waste to keep these ammunition, it's better to use them to fight, what if you succeed?" ”

After speaking, Ye Yuxuan put all the counted grenades in front of the gate, and then turned his head to look at Yui Uesugi on the side: "Yui, I should use the M500 I got not long ago later, you get ready first." ”

"No problem." Her answer was still as simple as that.

Ye Yuxuan adjusted his breathing slightly to make sure he was in the best state of being awake, and then turned on the naked-eye visual enhancement and turned on a bunch of accessibility functions that he had never used before to accomplish the desired goal.

With the official launch of the program, the world in front of Ye Yuxuan's eyes has undergone earth-shaking changes, his vision has become clearer, and all kinds of details are clear; Various data tables floated in front of his eyes, helping him better understand the results he was seeing...... Good eyes, plus such a large number of functional plug-ins, are stunned to make it look like a mechanical prosthetic eye.

"Start scanning!" Ye Yuxuan silently recited the instructions in his heart, which also meant that the scanning had officially begun
