Advantages...

Merlin felt as though some sort of blinding light would attack his sight as soon as the door opened as he remembered all those scenes from movies where a something insanely expensive, or elaborate was revealed or unveiled to the world.

However, nothing of the sort happened.

Beyond the door lay the same dirt tunnel they had been on the whole time, however, the walls this time had also been flattened, making it look like a giant had pushed a cookie cutter straight into the ground horizontally and made a perfect square tunnel.

Merlin suppressed his disappointment and continued following behind Dulir and his students, along with the guards.

The speed at which the group was moving at could be considered as Merlin's fastest sprint including the use of magic, when he was at the peak of Tier 3. Now, however, it was barely half his speed even without using magic. This was not only due to his Tier evolution but also race evolution, which had exponentially improved Merlin's physical body along with the other mutations.

Within a few minutes of running at a speed which a normal human at Tier 0 lv 0 could only describe as a blur, The group reached another gate, this one seemingly even thicker and stronger than the previous one.

After about an hour of running, and passing by around 10 gates, the group finally reached something different to the monotonous routine.

In front of Merlin, the tunnel's ceiling and walls steeply went outward as the size of the tunnel grew to almost 3 times of what it was before, and an enormous gate completely incomparable to the ones before.

Not only was the design of the double door rather exquisite, the material itself was leagues above the previous ones.

If the other gates were made of steel, then these double doors were made of adamantium.[1] This gate was undoubtedly at Tier 5, and safely situated in the middle of the Tier, not 'just barely' reaching Tier 5.

Merlin just stood in his place, clearly in awe of the gate.

Seeing this, Dulir snickered with a satisfied expression. 'At least he knows how to appreciate my sweat ad blood.'

"Let's enter."

Merlin entered through the open golden gates and walked into a bustling city, with 3 meter tall dwarf giants everywhere, and the streets and buildings were enlarged proportionally.

Although Merlin could not see electricity, he could most definitely feel that almost half of the existences here were Tier 4, while the not a single child was below Tier 3.

'It appears the dwarven race is born at Tier 3…'

Merlin gleamed something interesting from just seeing the citizens of the dwarven race.

'Tch, why do they get such a big advantage compared to humans, elves and demons…'
