Half an hour later.

Grim met the miserable 2nd Order Dragonman Zacha.

It was fortunate that it was not infected by the Void energy in the Big Bang. But it was also its misfortune, making it a blood food for the Brontosaurus Arms to maintain his strength.

Originally, Grim thought that it was already dead, but who knew that it was wrapped up with the earth element, only to find that it was only dying, and it still had its last breath.

Almost without hesitation, Grim took out the life potion from his body and poured it down.

Unfortunately, this may have saved its life, but it could not restore its flesh-and-blood limbs and part of its torso that had been eaten by the Brontosaurus. If you want to recover further, you can only transfer to the Flame Throne Witch Tower to slowly recuperate.

A horrific injury like this is hard to repair completely without a few months.

Although there are many methods of rapid growth of flesh and body in witchcraft, they are all visions caused by the temporary stimulation of life force at the moment of life and death. Once the witchcraft is revoked, the defective part of the flesh still needs to be carefully conditioned and repaired to recover.

However, with the powerful physique of a second-order dragonman, as long as it is given enough food and energy, the speed of repairing the flesh * body must be several times faster than that of a wizard with a weak physique.

Although the dragonman Zacha is dying, it has always maintained a clear consciousness. Even when Grim rescued it from the Brontosaurus, it also conveyed a trace of gratitude with its weak mental power.

Although I don't know how sincere this gratitude is, it also makes Grim see the possibility of subduing the other party!

There was no time to take it slowly* this second-order dragonman, and Grim directly handed it over to the poisonous concubine Endo, allowing him to play freely. He, on the other hand, refocused his full attention on the silent battle underground.

In less than a quarter of an hour, the earth elemental army that Grim had built with all his might had lost nearly twenty percent. And the basic value of the twenty wizard-level earth elements has also reached the level of fifty thousand magic crystals. If you put them all into the wizard market, the estimated value is around 300,000.

And the benefits brought to Grim by the death of twenty earth elementals only made the thunder dragon Arms more miserable, and some of the thunder and lightning power that had just accumulated was squandered again.

Although the images fed back through the earth elemental showed that the third-order thunder dragon was already crumbling, it seemed that with a little more effort, it would be possible to bring it down. However, Grim still didn't dare to be careless, let alone fight in person, so he could only command the Earth Elemental Demon Golem to roam around the periphery of the Thunder Dragon, waiting for an opportunity to sneak attack.

With them here, the brontosaurus didn't want to dig it out smoothly.

Even under Grim's command, the Earth Elemental Golem collapsed the passage dug behind the Thunder Dragon. In this way, the other party will not even have a way to retreat.

After besieging the other party layer by layer, Grim began to constantly send the Earth Elemental Demon Golem over to shout, wanting to take the opportunity to subdue this thunder dragon with terrifying third-order strength. But unfortunately, every time the golem 'messenger' is killed by the opponent's claw, and then a new round of battle is triggered.

After many fruitless attempts, Grim was also ruthless, no longer sending envoys to surrender, but going all out to strangle the isolated 3rd Order Thunder Dragon.

If you put it in the past, Grim wouldn't even dare to think about it. But now, by chance, he accidentally bumped into a 'big fish'. If such an opportunity is lost, Grim will not forgive himself no matter what!

Excavation work on the ground has been suspended, and all the goblins have died down, silently waiting for news.

As the protagonists of the battle, Grim and Bilis, one hiding in a cabin and the other in a tent, both remotely commanded their subordinates, and launched a non-stop harassment and siege on the third-order thunder dragon in a short section of the tunnel.

No matter how strong the strength of the third-order thunder dragon is, the sky is the stage for it to show itself. And the underground is where it is destined to be a nightmare for a lifetime!

If Arms is ready to dig away, the Earth Golem rushes into the tunnels and uses their natural instincts to strengthen the dirt around the tunnels. Although this does not reach the point of turning concrete into stone, it also makes the other party's excavation more than ten times more difficult.

If Arms abandons digging and instead attacks the Earth elemental, the golems retreat into the dirt and entangle each other with a non-stop stream of spears and mire spells.

Using this method, hundreds of demon golems and scorpions roamed around the thunder dragon and took turns to fight, which also reduced the elemental consumption of the demon golems. After all, in the low-demon goblin plane, the thunder dragon cannot be replenished by the elements, and the same is true for the demon golem.

It's just that one side is strong, the other side is strong, and the two sides are fighting underground, and it can be seen that whoever can't hold it first will fall first.

And in this regard, it is obvious that the Thunder Dragon does not have the advantage!

This covert war that took place underground lasted for half a month, and the 3rd order thunder dragon Armes who had run out of oil and lamps had fallen and became a captive of the earth elemental demon golem.

Harvesting a Tier 2 dragon and a Tier 3 Thunder Dragon in one go, this surprise simply made Grim feel excited.

But bigger surprises are yet to come.

Meandering down the tunnel dug by the Thunder Dragon, the two scorpions sent by Billis, the Worm Witch, actually touched the scene of the explosion of the space furnace. It had become a strange void of energy, and all matter that floated into it would be annihilated into fine dust that was indiscernible to the naked eye, and then re-ejected.

And these re-ejected dust are attached to extremely strong energy radiation, and one of the stinging scorpions in Biliss was sprayed by a column of dust because it was too close, and the body of the insect directly disintegrated.

From a distance, the Energy Void looked like a huge black stone with a diameter of ten meters, surrounded by fine energy dust. In the terrifying loud rumbling sound, the center of the Energy Void couldn't help but spew out a stream of energy with multicolored dazzling light.

The flow of energy filtered through the dust layer of the stone shell, no longer as violent and chaotic as when it first appeared, and intertwined with the laws of the goblin plane, thus turning into streams of extremely pure magical elements that escaped to the periphery.

Seeing such a spectacle, of course, Bilis was puzzled, but Grim, who had a copy of the wizard's book in his head, recognized it at a glance.

"Drop, discover a wild source of magic...... After measurement, the concentration of magic power is 78.25%, and the magic attribute is biased towards rage, which is not suitable for wizards to drink directly......"

"Magical Source!" Grim's eyes lit up.

Seriously, this is a wild, unconcocted and untamed source of magic.

Although it was created as a result of a bizarre explosion, it fits all the descriptions of the wizard's source of magic in Grim's memory.

The so-called source of magic is actually just a name for it by wizards, and it is actually nothing more than an energy meeting point between an extraterritorial void and a dimensional space. Here, the furious energy of the extraterritorial void came into contact with the dimensional space, and then a kind of energy siphoning phenomenon appeared.

It is precisely because of the existence of the source of mana that the dimensional space can be replenished with the energy of the extraterritorial void, thus maintaining a stable mana index internally. And it is precisely because of the lack of this wild source of magic power in the goblin plane that the magic elements inside the plane are thin, thus becoming the notorious low magic plane.

Here, Grim has to sigh at the strangeness of fate!

If that third-order brontolldragon knew that a source of magic had been born in the core area of the Big Bang, then it would definitely not bury its head in the outward excavation. If it can stay within the range of the source of the magic power, it will replenish itself with the power of thunder and lightning. At that time, who else in the entire goblin plane will be able to stop a 3rd order brontosaurus in its heyday?

But it was obviously frightened by the terrible explosion, and only wanted to get away from this terrible place, but it didn't know that it had missed a chance for it to turn over in vain!

The source of magic is definitely a gift from heaven for powerful magical creatures, but for those who are not strong enough, it is comparable to the forbidden land of death.

Tier 1 wizards are still too fragile, and once they get close to the source of magical power, they are very likely to be directly assimilated into demon spirits with no body and only broken consciousness. As a second-order wizard, Grim has completed the elementalization of his body and spirit, and not only will he not be harmed when he is close to the source of magic, but he can feel the rich magical aura that comes to his face all the time.

If he depletes all of his elemental power during the battle, he only needs to bathe in the source of mana for 5 minutes to replenish all of his elemental depletion.

The significance of such a treasure to an elemental wizard is comparable to that of an Origin Relic!

And Grim remembers that it was written in books that this source of magic could be transferred through witchcraft. If you load it into the Magic Furnace that you have sketched out of your design, you can increase the power of the Magic Furnace by more than ten times.

Standing twenty meters from the black sphere, Grim sensed the structure inside the source of the magic. But no matter how he sensed it, the energy void in the center of the source of magic was a simple darkness in his mind.

Neither witchcraft tests nor psychic perception can get any feedback or response there.

And once his spiritual power penetrates into it, it will be swallowed up by a strange spirit.

Yes, it was devoured, not missing!

Grim stood for a long time, and finally sighed helplessly.

The source of the magic is indeed mysterious enough, wonderful enough, and with his current strength, he is not qualified to probe the secrets inside it.

Set up the area where the source of mana is located and sign it off, and then try to close it.

Here's the time for Grim to roam the underground!

The terrifying underworld where the 3rd Order Brontosaurus could not travel freely, but Grim could walk on the ground as smoothly as he could. And he relied on the powerful support he relied on to make his fortune - the Elemental Golem.

Originally, he wanted to give the task of developing the Steel City to Worm Witch Billis, but now it seems that even he underestimated the value of this place. Not to mention the door of the plane that did not show its head, even the things that arrived now have greatly exceeded his psychological expectations.

If you step on this place completely, maybe there will be a bigger harvest!
