"With so many metal spiritual materials, I think someone must have placed them on purpose!"

Xu Hong, who stepped into the stone room, was surprised for a while, his mind was a little restrained, and after thinking about it slightly, he knew that this place was greasy, but Xu Hong didn't care, so thoughtful, setting up this secret room to hide treasures, and cultivating would definitely not exceed the realm of "building a foundation".

And Xu Hong, who has the divine idea of "late stage of foundation building", once he casts the "mecha transformation" and "Jindan strong", he is safe to protect himself, yes, after a little thought, he has a decision, and he bows his head slightly.

"Well, and don't care about anything else, it's currently important to upgrade the "six-star mecha"!"

Immediately, Xu Hong, who had a decision in his heart, shook his body and swept out of the passage of the stone chamber again, and then, roughly arranged, as a cover, he returned again.

"Well, it's time to evolve the "Six-Star Mecha"!"

Xu Hong, who returned to the "Passage Stone Room" again, stared at a large number of second- and third-level "iron essences" in the corner, and a trace of heat flashed in his eyes, and now, the materials needed for the promotion of the "six-star mecha" are only the second- and third-level "iron essences" in the stone room, and I am afraid that it is more than enough.

Subsequently, Xu Hong, who was a little excited in his heart, raised his wrist lightly after whispering, and directly ingested the second- and third-level "iron essence" in the corner into the reactor of the "six-star mecha" in piles.

"Drop: Insert secondary iron essence with a reserve of one percent. ”

"Drip: Insert tertiary iron essence with a reserve of three percent. ”

......

"Drip: Insert the third-level iron essence, and the promotion reserve is completed, 100%!"

Compared with the "first-level iron essence", the second- and third-level "iron essence" that can be used as the top-level intermediate and high-grade magic weapon materials is more preferable, and it is easier to promote the promotion of the "six-star mecha".

With pieces of dark brown second- and third-level "iron essence", Xu Hong continuously ingested into the "reactor" space of the "mecha source bead", and bursts of "intelligent light brain" prompts sounded one after another.

It wasn't until Xu Hong emptied most of the second- and third-level "iron essences" in the corners of the stone chamber that the "intelligent light brain" prompted the completion of the promotion reserves, however, at this time, there were already nearly a thousand remaining "third-level iron essences".

Then, Xu Hong, who did not stop, flipped his wrist, and a pile of spiritual light flashed, and the "lower grade spirit stones" full of spiritual energy appeared out of thin air one by one, and they were continuously ingested into the "energy furnace" of the "mecha source bead" by Xu Hong without pity.

"Drop: Energy Furnace Reserves, three percent!"

"Drop: Energy Furnace Reserves, five percent!"

......

"Drop: Energy Furnace Promotion Reserve Complete, 100 percent!"

In a burst of "Intelligent Light Brain" prompt sound, after nearly 80,000 "Lower-grade Spirit Stones" were ingested into the "Energy Furnace", the preparations for the upgrade of the "Mecha Source Bead" were completely completed, and with so many spirit stones, four "top-level medium magic weapons" could already be purchased.

The consumption of nearly 80,000 "lower grade spirit stones" did not empty Xu Hong's "storage ring", but it was not far away, and then, Xu Hong, whose face was tense, decisively and directly issued the last order.

"Level up!"

"Buzz ......"

Suddenly, Xu Hong's mind moved, and the bright silver "Six-Star Mecha Yuan Bead" suspended in the sea of divine court consciousness trembled slightly, and it slowly turned as if it was being moved by a strange force.

"Drop: One percent of progress. ”

"Drop: Two percent progression. ”

......

"Drop: Twenty-one percent progress. ”

The promotion of the "Mecha Source Bead", as the level increases, its energy fusion process also becomes more slow, after more than half an hour of effort, although there is a metal spirit material of the quality of "third-level iron essence", plus the rapid combustion of the "spirit stone", it is only the progress of completing the "twenty-one percent".

"Drop: 100% progress, upgrade the "Seven-Star Mecha" complete!"

I don't know how long it will take, the "Six-Star Mecha Yuan Zhu" suspended and rotating in the sea of Divine Court consciousness suddenly stopped, and at the same time, the prompt sound of the successfully upgraded "Intelligent Light Brain" sounded in Xu Hong's mind, making Xu Hong, who was tense, exhale lightly, and this time, the time taken to promote the "Seven-Star Mecha" has reached nearly four hours.

However, the power of the "Seven-Star Mecha" is enough to make Xu Hong, who has been waiting for a long time, happy, only the armor after transformation, and its material has been upgraded to the "top-level low-grade magic weapon" Cheng Dù, I believe that it should not be a problem to resist the slash of the "top-level magic sword".

More importantly, as long as you are willing to give up the spirit stone, the power of the "Seven-Star Spiritual Energy Cannon" is enough to kill the average "late stage of foundation building" great monks, but, with the burning of 40,000 "lower grade spirit stones", as a boost, Rao is Xu Hong has the support of the "Great Wilderness Spirit Shop", if there is no windfall, if you want to unscrupulously stimulate the "Seven-Star Spiritual Cannon", you can't.

"Whew...... , Seven-Star Mecha!"

Seeing that the "Mecha Source Pearl" was finally promoted, Xu Hong, who dismantled the small "Iron Essence" spirit mine and won thousands of "Iron Essence" again, exhaled lightly, his expression soothed, and with the "Seven-Star Spiritual Energy Cannon" beside him, Xu Hong's overall strength can be said to have surged again.

Then, sensing the "Seven-Star Mecha Yuan Zhu" quietly suspended in the sea of Divine Court Consciousness for a moment, Xu Hong, who was slightly condensed, looked slightly condensed, and while standing up, he whispered inexplicably in his mouth.

"Well, presumably the friends outside are already waiting in a hurry, it's time to send them on their way!"

Immediately, he picked up the last remaining nearly 1,000 pieces of "third-level iron essence", Xu Hong, who had a leisurely expression on his face, his body swayed, the corners of his mouth were slightly upturned, and he hurried towards the outside of the "Passage Stone Room" without hurrying.

"Crunch ......"

"Well, it turned out that it was just a monk in the middle stage of foundation building, and he dared to steal my treasure!"

A "crunch" sound passed, and as Xu Hong slowly stepped out of the passage, at the corner of the cliff in the distance, a loud shout was suddenly heard, and at the same time, a "top-level high-grade magic sword" carrying a great momentum turned into a streamer, mixed with angry anger, crossed the distance, and attacked Xu Hong directly.

"Shaft, die!"

As a great monk of the "Foundation Building" realm, since he was sent here by the sect "Cangyun Sect" to govern part of the mine passages, "Black Yunzi" has been like a fish in water, quite comfortable, and has been selling spiritual ore metals outside the secret collection.

Not only did the magic weapon in his body rise step by step from the "high-level superior" level, and even replaced it with a "top-level high-grade magic weapon" worth 30,000 spirit stones a year ago, but also a body of cultivation, with the support of a large number of resources, it was also a rising tide, from the "middle stage of foundation building" to the realm of "late stage of foundation building".

However, what he couldn't imagine was that when the sect completely gave up the "Xuantie Waste Mine", the "Passage Stone Room" that he secretly hoarded was actually taken by outsiders and occupied and looted.

I never thought that I would be the first to pick peaches by a monk in the "middle stage of foundation building", how could "Hei Yunzi" let go of such a person who destroyed the wealth he had planned for a long time, yes, from a distance, Xu Hong was only in the "middle stage of foundation building" realm cultivation, and "Hei Yunzi" appeared angrily and fought up.
