As they flew towards the depths of the Cardola Desert.
The surrounding environment became increasingly harsh, with hot yellow sand swirling in the air.
Under the scorching sun, the entire Cardora Desert felt like a giant furnace, and the air visibly distorted, as if it were boiling water.
Occasionally, they would come across dried animal skeletons mixed in the sand.
However, the extremely harsh environment did not deter Rennes from moving forward, he relied on the energy shield generated by the Lava Dragon monster to isolate the external flying sand and high temperatures.
Rennes held a map, constantly discerning and correcting the direction, and it seemed that the Lava Giant monster and the immense pressure emanating from Rennes were noticed, so no foolish desert monsters came to cause trouble making the journey quite smooth.
After half a day, Rennes successfully arrived at the deepest part of the Cardora Desert, he stopped near a rugged sand dune.
According to the map, the ruins of the lost civilization were nearby.
However, all he saw was a sea of yellow sand and strange rocks, there was absolutely no sign of any ruins.
Clearly, the ruins were either buried by the sand, or hidden by a magic array or some other special means.
After some investigation, Rennes did not find any traces of a magic array nearby.
"It seems that this ancient ruin, which has endured countless years, must have been buried by the sand."
He made a guess in his mind, so Rennes immediately took action.
In order to prevent unintentional damage to the ruins, he did not directly destroy the sand dune with violence, instead, he used a 6th level arcane Art - Summoning of a Super Large Earth Elemental, thus the spatial gate leading to the Earth Elemental plane opened.
A giant elemental creature, about twenty meters tall and composed entirely of solid rock, walked out from it, Rennes then immediately released the spell nine times in a row, ten super large earth elementals lined up neatly in front of him, awaiting orders.
Under Rennes' command, these ten super large earth elementals instantly transformed into super excavators. (As they say: Modern problems, require modern solutions.)
Using their innate earth magic, they slowly excavated the massive sand dune, so with the efforts of the super large earth elementals, in less than ten minutes, the gigantic sand dune in front of me has been completely leveled by the super-sized earth elemental summoned by Rennes.
However, still, he couldn't see anything related to the ruins of a lost civilization.
"Keep digging!"
Receiving the command once again, the ten super-sized earth elementals continued to dig downwards.
Five meters!
Ten meters!
Fifteen meters!
They kept digging until they reached a depth of about two hundred meters underground.
Finally, something different appeared, it was no longer yellow sand, but a wall made of some tough magic stones.
It was obvious, this is most likely a part of the ruins of a lost civilization.
"We finally found it!" A hint of joy appeared on Rennes' face.
Immediately, he ordered the ten super-sized earth elementals to clear the yellow sand along the wall.
After ten minutes, Rennes with the help of the ten super-sized earth elementals successfully found the entrance to this lost civilization., it was a dark golden gate, made entirely of refined gold, seemingly engraved with an extremely advanced magic array, even after countless years of erosion, this gate still functions normally, rejecting all unfamiliar visitors from entering the ruins.
However, this obviously did not pose a challenge for Rennes. A master of magic arrays.
After spending more than ten minutes, Rennes successfully deciphered the magic array enveloping the gate, severing the energy connection between the gate and the wall.
Creak!
Without the support of the magic array, Rennes easily pushed open the metal gate in front of him, but he didn't rush inside.
After all, this refined gold gate weighs at least half a ton, its value can be considered quite high, so he dismantled the gate and stored it in his spatial ring. (Bruh, I thought him not rushing inside is because of him being cautious but this, and I'm not complaining because that gate probably worth few hundred mil, so…)
With a successful opening, Rennes couldn't help but anticipate the treasures inside the ruins even more.
Since the lava dragon monster is too large to enter the ruins, Rennes could only let it guard the entrance, acting as a gatekeeper, preventing others from trespassing.
After everything was arranged, Rennes strode through the gate and walked towards the ruins, the interior of the ruins was extremely complex, there were a lot of crisscrossing corridors.
After some exploration, Rennes discovered that these ruins seemed to be a "research institute" of that lost civilization, exploring and studying something special, because he saw many research equipment inside the ruins, and combined with the information obtained from the system, Rennes had an astonishing guess in his mind.
"Could this ruin be a research institute for studying deities and gods?"
After all, according to the information previously given by the system, these ruins were related to a fallen god.
Research institute + fallen deity, this combination of keywords was hard not to associate with some thrilling forbidden research projects.
For example, creating artificial deities.
Tens of thousands of years ago, the arcane civilization of Netheril had also studied deities, attempting to decipher the secrets of their immortality and omnipotence, and then, through artificial means, they mass-produced deities. (Science for the win.)
However, this research ultimately ended in failure.
If his guess was correct, this lost civilization probably did something similar to that arcane civilization.
"It seems that this ruin is even more dangerous than I thought."
Thinking of this, Rennes's eyes also became serious, a ruin for researching deities, how many protective measures were arranged inside such a place, and how strict were they?
Even someone as powerful as a true god would probably find it difficult to leave unscathed.
However, Rennes had no intention of backing down. After all, time was the most terrifying thing in the world, except for the said immortal deities and gods with infinite lifespans, nothing could withstand the erosion of time.
After experiencing such a long period of time and without anyone maintaining it, it was uncertain how many of the protective measures inside this ruin were still effective, so there was no need to scare himself.
Of course, it was still necessary to be cautious.
In the subsequent exploration of the ruins, Rennes's actions became much more cautious, he forcefully summoned some low-level demons with magic to help him explore the way.
And this move was extremely effective, some deeply hidden and still functioning defensive measures have been triggered, it has saved Rennes a lot of trouble.
As for the cost, those low-level demons suffered heavy casualties, either they were exiled to the endless space rift or they were severely injured and sent back to the abyssal plane by the contract. (Kinda feel bad for them :< )
There were even a few unlucky ones, they were hit by a level 9 magic spell - the Great Disintegration Spell.
Without even triggering the contract, they directly turned into basic particles and dissipated.
Rennes was sweating coldly at the time, if he had been hit by this Great Disintegration Spell, even if he didn't die, the equipment he was wearing would probably be completely destroyed.
The Great Disintegration Spell is also known by another famous nickname, "The Great Bankruptcy Spell", because there was once a battle between two half-god Grade mages.
One of the half-god Grade mages was hit by this spell, although he luckily didn't die, all of his legendary magical equipment were disintegrated, even the space ring that stored his lifelong savings exploded, all the treasures disappeared into the endless void. He went bankrupt on the spot, causing him to go into a mental breakdown after the fight.
That's why, this level 9 magic spell has such a terrible "reputation".
"It's so damn terrifying." Rennes still had lingering fears.
He had only obtained the top-tier legendary weapon, the Sun fire divine sword, a few days ago, if it were to be disintegrated by this disgusting spell, then he would truly have nothing left to cry about.
Thinking of this, Rennes couldn't help but feel extremely grateful for the demons' 'voluntary' sacrifice.
Without their help, his great sword would truly be in great danger this time. (Abyssal demons who died: You're welcome!)
Spending over an hour, exploring all the areas, he didn't find anything valuable.
However, he did find the passage to the next floor, through the stairs, Rennes successfully arrived at the underground second floor of this ruin. Here, he made a very significant discovery...
