Castle of Black Iron

Watching the two snakes engulfing each other, Zhang Tie had a doubt——why most of the religious totems of humans were reptiles or carried the features of reptiles?

In human history, even races and civilizations on different continents or subcontinents which had no communication with each other shared same elements in their religious totems.

In this world, there were too many kinds of animals; then why only reptiles occupied such a high percentage among their religious totems?

Zhang Tie didn't know the answer, nor did he believe that the others in this world knew it; because the knowledge and fields might be involved with great secrets in far-ancient times. Therefore, people in this age were confused about the religious totems which shared the same elements.

Thankfully, it was just a doubt. As Zhang Tie was not here for archaeological and academic study, he dropped this whim at once.

Under the totem comprising two snakes, there were some bizarre symbols, among which, Zhang Tie, even having no knowledge about astrology, could instantly see stars and two full moons in the sky.

There was not a single hole for key or crystal. As it was full of light nearby, the patterns on the gate became the only information.

The key to this gate was the power granted when two moons waxed.

As it was already mid-July, only less than two weeks left from full moons.

Drawing Bai Suxian's hand, Zhang Tie strutted forward a few footsteps as he pushed one hand against the gate forcefully.

Zhang Tie had such great strength that he could even press a piece of alloy flat by one hand. However, even though he pushed this gate with his full strength, this gate still remained still. It indicated that this gate could indeed not be destroyed by external force.

Zhang Tie tried to look through the gate and the ground by lotus-flower eyes. Pitifully, In front of the mysterious strength, Zhang Tie failed to see anything inside.

But...

'Yi...'

When Zhang Tie fixated onto those stars and full moons on the gate, Zhang Tie's heart slightly pounded.

Under his lotus-flower eyes, those stars and full moons should be an entity which remained still; however, strangely, the energy carried by those patterns was different than the rest of this gate in level. The color temperature of the two energies didn't completely coincide.

Without lotus-flower eyes, Zhang Tie could never discover such a difference.

However, because Zhang Tie didn't see the same full-moons gate before, he didn't know the meaning of the difference. Perhaps all the full-moons gates were the same. Therefore, Zhang Tie only felt a bit strange about it.

However, Zhang Tie didn't tell Bai Suxian about his discovery. After throwing another glance at this gate, Zhang Tie told Bai Suxian instantly, "Let's take a look at other gates!"

"Hmm!" Bai Suxian replied as she flew away with Zhang Tie towards another nearby full-moons gate, hand in hand.

"Have you seen a full-moons gate before?" Zhang Tie asked Bai Suxian secretly by battle strength.

Bai Suxian shook her head as she replied, "Not yet. However, my third uncle said he had seen many full-moons gates. Many hidden underground entrances of Dongtians were full-moons gates. In far-ancient times, many human activities and ceremonies were carried out according to natural phenomena so as to answer the call of nature perfectly and for the optimal effects. My third uncle told me just now that the six full-moons gates looked completely as same as that he had seen before. The waxing and waning of moons, the eclipse of the sun or the moons, specific constellations or stars in certain locations were all keys to natural phenomena gates. All those who have studied the tower of time and natural phenomena gates confirmed that these were natural phenomena gates!"

"Really?"

"What are you worried about?" Bai Suxian asked Zhang Tie with a smile as she added, "The full-moons gate could never be destroyed or triggered by human force. Don't you believe it's true?"

"Nah, let's take a look at other gates!"

The two people then circled around the tower of time while stopping in front of each full-moons gate and observing it seriously for a short while.

The six full-moons gates were completely the same. Additionally, all the patterns on the six gates didn't completely coincide with the rest of the gates in energy level as was discovered by Zhang Tie before.

After observing the gates, Zhang Tie and Bai Suxian seriously observed all the eight walls of this Dongtian.

There were metal sculptures of various vivid, grim, tan birds and beasts on the walls. However, all the sculptures shared a commonplace——eyes closed.

On each wall, there was a huge, white metal sculpture. If these sculptures could be sold, they were definitely priceless artworks. Zhang Tie found that some knights wanted to remove those sculptures, despite, in vain. These sculptures were organically integrated with the octahedral metal mountain, the tower of time, the ground and the dome of this underground space, which could hardly be ruined.

However, watching those sculptures, Zhang Tie gradually got a strange feeling because those sculptures were too familiar for him.

"Don't you feel a bit familiar with these sculptures on the walls alongside this place?" Zhang Tie asked Bai Suxian, suspending in the air in front of an over 100 m long metal sculpture in the shape of a grim snake with a pair of wings.

"Familiar? But we've not been here before..." Bai Suxian replied as she watched Zhang Tie with a bit surprised look.

"Think about it!" Zhang Tie gave her a tip as he pointed at the sculpture of that weird snake, "In the lobby full of war puppets in the bloody sacrifice hieron when we were in Earth-elements Realm..."
