Chapter 192： Hundred Times Xuan Ling Iron

At this time, in this intricate passage, many places were surging, and it was also very chaotic.

Of course, some warriors who find their treasures will naturally arouse others' jealousy, and the ultimate result is that when the treasure is obtained first, fierce competition will soon erupt, and one by one will be beaten.

As for the so-called swords and treasures in the tomb mansion, or pill pill elixir, Yang Zilei has the munitions and rations of the system mall, and naturally he does not look at the others.

Straightforwardly follow the passage he chose and advance quickly into the depths.

"It is said that the talisman puppet master's collection, in addition to the refined talisman puppets, the most important thing is the various refining materials."

As he rushed, Yang Zilei muttered to himself, "I don't know if there are any rare metal materials in this tomb mansion."

After thinking about it, Yang Zilei appeared again in three or two passages in front of him. According to instinctive habits, he quickly swept in directly to the right passage.

After a while, Yang Zilei's steps slowed down, and he had already reached the end of the passage.

Yang Zilei raised his eyes and looked at a giant gate at the end of the passage.

As he approached the gate, Yang Zilei was surprised to discover that this was not the ordinary stone gates seen in the passage before, but was made of a peculiar metal, containing aura fluctuations, and its solidity can be imagined.

"Xuanling Iron?!"

Yang Zilei's eyes narrowed slightly, and he saw that the material of the metal gate was a high-grade metal.

For example, ling spar and ordinary stone, although the origin of the two is stone, but the value is very different.

Because the value of this mysterious spirit iron is very expensive, Yang Zilei has always been devouring metal conversion strengthening points and only purchasing the most common iron ore or low-grade bronze metals.

He had never swallowed this kind of high-grade metal before.

"Such extravagant things can't be wasted."

Yang Zilei licked his lips, and quickly pressed his palm against the metal door.

"Om——!"

Sure enough, just as Yang Zilei expected, the mysterious runes looming on the door suddenly flashed, and an obscure energy wave filled.

But just when that energy was about to shake Yang Zilei's palm away.

"Swallow!"

Yang Zilei was the first to issue instructions to the system.

In an instant, the metal gate in front of Yang Zilei's eyes disappeared out of thin air in an instant, including the rune energy, was also wiped out.

"Ding, congratulations to the host for swallowing a thousand catties of profound spirit iron, successfully converted into 100,000 strengthening points."

"Warm reminder, the host has accumulated 250,000 strengthening points and has the conditions to upgrade Wuhun."

Listening to the system electronic synthesis sound in his mind, Yang Zilei's heart was shocked, and his eyes widened suddenly.

"This profound spirit iron conversion enhancement point is a hundred times more than ordinary metal!"

Yang Zilei was inexplicably surprised, and obviously did not expect that this high-grade metal with aura could have so many multiples.

Knowing this a long time ago, he didn't have to work so hard to purchase a large amount of ordinary metals, and directly get a few hundred catties, several thousand catties of profound spirit iron, and do it in one step.

"It seems that you will have to try again in the future."

Yang Zilei muttered thoughtfully, but fortunately, high-grade metals can convert hundreds of times stronger points than catties.

Otherwise, the larger the purchase amount, the more troublesome it will only be.

"Upgrade Wuhun."

After checking the system's strengthening points, there are already 270,000 values. Yang Zilei didn't even think about it, he just issued a command to the system.

"Ding, the seventh rank martial spirit has been successfully upgraded. Congratulations to the host martial spirit for evolving into a tank form, with a strengthening point of 160,000."

Om——!

Suddenly, Yang Zilei felt the spiritual power surge in his body, and immediately the cannon spirit in the sea of ​​Dantian cave, squirming quickly, and in a flash, it changed into a combat tank spirit.
