The Eastern Emperor sent a message to Meng Gu and invited him to the Eastern Imperial Palace.

The Chinese martial arts officials of the Golden Hall of Wuji Immortal Mountain were not there, and Zhao Tongfan and Chu Yue were chatting with the Eastern Emperor Zhao Wuzhi.

Seeing that Meng Gu had arrived, the Eastern Emperor hurriedly beckoned him over, and said with a smile: "My words count, since I promised to give you a grand gift, I will never break my word." Let's go, follow me to the Eastern Emperor's Treasury!"

The three of them were overjoyed and followed the Eastern Emperor to the depths of the palace.

The Donghuang Treasury is a treasure treasury established by the Zhao royal family after gaining a foothold in the Dongsheng Divine Realm, which treasures the treasures, exercises and secret history documents collected by the Eastern Emperors of the past dynasties.

Not to mention Chu Yue and Meng Gu, even Zhao Qianfan, the daughter of the Eastern Emperor, has never entered the Eastern Emperor's treasury.

In the depths of the East Imperial Palace, a stone gate leading to the ground is engraved with the words "Forbidden Land".

Under the guidance of the Eastern Emperor, the three of them passed through many barriers, and finally came to an underground palace.

The Eastern Emperor's brocade sleeves waved, and the underground palace was immediately lit up, and countless rare treasures came into view!

"That side is all rare spirit ore, you can pick it at will, if you like anything else, it doesn't hurt to take it!" Donghuang Zhao Wuzhi said generously.

Meng Gu was not interested in rare treasures, wandering around the dungeon at will, and a night pearl on the high platform on the east side made him quite curious, and he stepped forward and stretched out his hand, wanting to take it down and take a look.

Seeing this, the Eastern Emperor hurriedly ran over and said, "Meng Gu, you can do anything except this, but I can't afford to give this bead to Zhao Wuzhi......"

Meng Gu smiled and said, "Lord Donghuang, if I guess correctly, it is the secret treasure of mortal martial arts." ”

Donghuang gave a thumbs up in admiration and nodded.

Meng Gu took the bead and weighed it in his hand, the material was very light, it felt slightly cool, and it was somewhat similar to the Hundred Ghost Dao token, but he didn't feel the existence of mortal martial arts at all.

He turned back to the Eastern Emperor and smiled and said, "Look, without the Ninety-Five Order, you really can't cultivate mortals. He put the beads back in their place and continued to look east and west, and finally his eyes fell on the two anvils in the corner of the dungeon.

Meng Gu ran over in a few steps, wiped off the thick dust on the anvil, and examined it carefully, as if he had discovered a new continent.

Donghuang followed and said, "These two anvils were left by the ancestors of my Zhao family, they should be things used by Master Ou Yezi, and they may be placed in this treasure house to keep a memory." ”

Meng Gu pointed to one of the anvils and asked, "But there are still things left with this anvil?"

"Yes, there is also a handscroll of Master Ou Yezi, but no one has been able to read it for so many years. ”

After speaking, the Eastern Emperor walked to a pile of classics, flipped through them for a long time, and took out a scroll and handed it to Meng Gu.

Meng Gu opened the scroll and looked at it for a long time, and gradually his eyes lit up!

At this time, everyone else also gathered and looked at him curiously.

Meng Gu said excitedly: "This is the blueprint of the Xuanyuan Sword!"

"Excalibur-Xuanyuan?!" Everyone including the Eastern Emperor was stunned.

Legend has it that the Xuanyuan Sword was one of the divine swords cast by Ou Yezi for the ancestors of the Eastern Emperor, and it was later broken in the melee of the three clans due to excessive urging of the mortal great array.

This drawing in Meng Gu's hand recorded in detail the casting method of the Xuanyuan sword, not only that, but it may be that Ou Yezi was worried that future generations would not have enough ability to cast this sword again, so he deliberately carved the sword mold of the Xuanyuan sword on the anvil, which made the forging difficulty much less.

Such a treasure has been in the treasure house for thousands of years......

The Eastern Emperor stared at Meng Gu and asked, "Can you forge this sword?"

Meng Gu looked at the drawings repeatedly, thought about it for a long time, and then searched for various materials according to the drawings in the treasure house.

In the end, he said with palpitations: "According to this drawing, the Xuanyuan Sword should be an immortal divine weapon, the material requirements are very harsh, the materials I found are only enough to cast once, only success is not allowed to fail, and now I dare not say that I am 100% sure." If you are willing, Lord Donghuang, can you allow me to test the water with another anvil first?"

Donghuang's face was full of doubts, what is the other anvil? How to test the water? Since Meng Gu brought it up, let him try it.

"I said earlier, you can take any of the treasures here, how are you going to test the waters?"

Meng Gu pointed to another anvil and said: "That anvil belongs to the Ou Yezi family and Mo Ye, and there are also two sword molds engraved on it, I just have the drawings of those two swords! I want to try it first, if it succeeds, I am willing to reforge Xuanyuan for the Eastern Emperor!"

Of course the Eastern Emperor agreed, and everyone gathered around Meng Gu, wanting to see him forge a sword!

Meng Gu has always wanted to forge the Cadre Mo Evil Twin Swords in the "Mortal Treasure" by chance, but with his current forging skills, it is impossible to forge the Cadre Mo Evil.

Today's sudden discovery of these two anvils opened his eyes, and he couldn't help but admire Ou Yezi's foresight!

Meng Gu dragged the anvil to the center of the underground palace, found some spiritual ore and piled it up beside him, and took out the spiritual ore brought back from the bottom of the magma in Ouyu Valley, ready to start work.

The Eastern Emperor formed a formation on the side, and a delicate small array of true fire appeared next to the anvil.

The magic circle of the silver-level powerhouse is really different, the true fire in the array is refined and pure, and it has reached an extremely high temperature under the control of the Eastern Emperor.

Smelting, purification. Meng Gu carefully fused all kinds of spirit ores, but fortunately, the materials in the Eastern Emperor's Treasury were extremely pure, greatly reducing the difficulty of refining.

Meng Gu carefully poured the molten water of the fused spirit ore into the sword mold, cast a soul gathering, absorbed the cold qi in the dungeon into his body, and instantly rose to level 8 of the stone steps!

Sen Luo's heart method is carried to the highest, and he accurately controls the qi of Xuanqi and cooperates with the drawings in his brain to hammer and forge according to the law, but fortunately, with the assistance of the carved sword mold, he can barely control the rhythm, and the sound of hammer forging resounded through the underground palace like a storm.

Wuji Immortal Mountain was originally sunny today, but at this moment, black clouds suddenly pressed to the top, forming a huge dark cloud vortex, and then the clouds split into black and white!

The masters of the major sects all looked up, and they were born with visions for no reason, and they didn't know what they portended......

The black and white clouds finally merged into a huge Taiji pattern, which hung over the Wuji Immortal Mountain like a magic circle and slowly swirled.

Suddenly, two heavenly thunders, one black and one white, were split from the eyes of the Taiji Yin and Yang fish, and they hit the East Palace impartially!

The guards were all shocked, fearing that the demon clan would attack, and they rushed into the palace to protect the Eastern Emperor, but they couldn't find anyone everywhere!

————————

Besides, in the underground palace of the Eastern Emperor's Treasure Vault, although Meng Gu's hammer forging method is sharp, everyone can't see a sword shape.

In the end, what he picked up and quenched was actually two lumps of iron lumps with scars on the surface and shaped like loofahs.

Everyone was curious, and found that this quenching method was also very different from before.

Meng Gu absorbed the surrounding Xuanqi and tightly wrapped the two iron lumps, and the iron lumps frantically absorbed the Xuanqi Qi!

Meng Gu obviously felt that the normal supply of Xuanqi Qi was far less than their absorption speed, so he grabbed a few pieces of rare spirit ore rough stones and transported them back to their source to turn them into Xuanqi Qi!

Those priceless spirit ores instantly came to naught, and they all turned into Xuan Qi and replenished into those two iron lumps, which was probably the most expensive forging in the history of the Dongsheng God Realm......

The two iron lumps were suspended in mid-air and spun rapidly, gradually turning one snow-white and the other jet-black. When the most critical moment came, Meng Gu didn't dare to be careless, and grabbed several pieces of rare spirit mineralized gas and threw them into it!

The speed of the iron pimple is getting faster and faster, vaguely generating a Tai Chi pattern, and the surrounding space vibrates slightly, and the qi of the Xuan Qi then turns into yin and yang, and the rigidity and softness push each other and merge into one!

Two heavenly thunderbolts, black and white, suddenly appeared on the dome of the dungeon! Several enchantments were nothing, as if they had passed through space and reached here!

With a loud bang, the thunder struck down from the sky! The white thunder hit the black iron lump, and the black thunder hit the white iron lump! The underground palace was suddenly turned upside down, and countless treasures turned into scorched earth!

The dust and smoke dissipated, Meng Gu covered his head and lay on the ground, Zhao Qianfan was so frightened that he pulled Chu Yue's arm tightly, Chu Yue protected her under him, Meng Gu secretly glanced at it and stuck out his tongue.

Eastern Emperor Zhao Wuzhi stood in front of them, holding the sky with one hand, and a thick protective barrier protected the three of them in the array.

Meng Gu scratched his head and stood up, frightened: If we didn't have Lord Donghuang by my side today, I'm afraid we would all die here......

Everyone stabilized their emotions and looked towards the anvil together, the anvil had been split apart by the thunder of the sky! If this fails, I don't know what year and month it will be able to cast the cadre Mo Xie......

The two pieces of iron lumps that were struck by the heavenly thunder were scattered aside, and there were cracks on them, Meng Gu walked over tremblingly, picked up the two pieces of iron lumps and looked at them, as soon as he used force in his hand, the surface of the scar Lai Lai began to fall off, and two pure and clear short swords appeared in his hand!

"Ahh
