Through these books, Ding Hao knew a lot about the [Spirit Realm], such as how the [Nine Spirit Clan] rose, how the [Nine Spirit City] was established, or what small forces did the [Spirit Realm] have in addition to the [Nine Spirit Clan], or ......

Although he got a lot of information, and it was indeed very useful, Ding Hao didn't find any news about [Heart of Heaven and Earth], and he didn't even see the name.

"I didn't expect that even the prince's mansion of the [Nine Spirit Clan] didn't have the slightest news about the [Heart of Heaven and Earth]......" After putting the last classics, Ding Hao sighed slightly.

"It seems that I can only inquire slowly, relying on the power of the prince, I may be able to find out the news about the [Heart of Heaven and Earth], but in this way, it will take a lot of time......"

"But in the [Primordial Realm], or in this [Spiritual Realm], I don't have any power, if I rely on me, trying to find the [Heart of Heaven and Earth] is like looking for a needle in a haystack, it is extremely difficult, speaking of which, I still have to rely on this prince now. ”

"That's it, take your time!" Ding Hao knew that it was useless to be in a hurry now, and quickly swept away the depression in his heart.

Since there is no news to be found here, and all the books have been read, Ding Hao will not stay here.

Turn around and walk outside.

Closing the door casually, Ding Hao was about to go back when a figure suddenly walked slowly from not far away, and soon came to him.

It is the military advisor who has been staying by the prince's side to give advice - Wusun Liuce!

"Strategist?"

"Brother Ding Hao, have you finished reading it so soon?" Wusun Liuce smiled and asked, "How is it, the books here have any effect on your previous memories of the [Spirit Realm]?"

Last night, when Ding Hao proposed to enter the Book Pavilion, Wusun Liuce was also beside him, so he naturally knew why Ding Hao was here.

"No!" Ding Hao shook his head, but said with a smile: "But because of the ancient books here, I also have a new understanding of the [Spirit Realm]. ”

"Well, that's fine. Usunyuce smiled.

Ding Hao suddenly thought of something, and said with a smile to Wusun Liuce: "The military advisor is well-informed, and must know a lot of things about the little known, if so, can the military advisor talk to me, so that I can increase my knowledge." ”

"Brother Ding Hao has won the award, and Liuce just has a little knowledge, where can he be considered knowledgeable, but since Brother Ding called it, Liuce should be willing to help. After Wusun Liuce said modestly, he did not shirk it, but looked very happy.

Although Wusun Liuce is a little old and is also the teacher of Prince Rongfu, when he talks to Ding Hao, he talks with his peers, and his tone is very polite.

Obviously, he also wants to befriend Ding Hao.

"Then there is the Lao Military Division!" Ding Hao smiled slightly, looked left and right, and said: "This is not a place to talk, if the military division comes to my residence, I will have a good talk, how about it?"

"That's exactly what I mean!" nodded the Wusun military division.

Soon, Ding Hao took the Wusun military division and returned to his residence.

The two sat opposite each other, Ding Hao took out the precious tea stored in the room, and immediately began to brew tea.

The hot water flowed into the tea set, soaking the tea leaves, and the hot air rose, and a smell of tea fragrance suddenly spread throughout the room.

Drinking fragrant tea, the two began to talk.

......

As Ding Hao imagined, Wusun Liuce has a wide range of knowledge, knows many strange things in the world, knows things that many people don't know, and even has unique insights into cultivating a method.

Many of these things are not even described in the library and in thousands of books.

Even if some of them are, they are not as detailed as Wusun Liuce.

Through him, Ding Hao also has a deep understanding of the [Spirit Realm], the [Nine Spirit Clan], and even other realms.

In order not to make the other party suspicious, in this conversation, Ding Hao did not ask about [Heart of Heaven and Earth], or anything else.

During the conversation, after listening to some of the things mentioned by Wusun Junshi, Ding Hao also expressed his views on some things.

And Ding Hao's views often coincide with the views of the Wusun military division, and the Wusun military division suddenly has a feeling of hating Ding Hao and forgetting the old man's friend.

Therefore, in the days that followed, he often came to Ding Hao and talked with him.

On this day, Wusun Military Division came to Ding Hao's room again.

As usual, Wusun Military Master began to talk about some of his knowledge, and after he finished saying this, Ding Hao said: "Military Master, I heard someone mention a strange thing called [Heart of Heaven and Earth] by chance, I don't know if you know this thing?"

"[Heart of Heaven and Earth]?"

"[Heart of Heaven and Earth] ...... [Heart of Heaven and Earth]...... I think I've seen this name somewhere......" Wusun Military Master raised his eyebrows slightly, thinking hard, and said so in his mouth.

"I've seen it!" Ding Hao was overjoyed when he heard this, his face remained unchanged, and he didn't bother him, quietly waiting for his answer.

Suddenly, Wusun Junshi seemed to think of something, looked at Ding Hao, and said slowly: "I did see the name of this [Heart of Heaven and Earth] in a classic, but I didn't pay attention to the details, I just remembered that there was this name." ”

"In the classics?" Ding Hao was overjoyed, his expression remained the same, and he asked him unhurriedly: "Where have you seen this classic book?"

Despite some news, Ding Hao was still very calm at this time.

Wusun Junshi didn't notice anything, and said eloquently: "Actually, I only saw this classic by chance, I remember that it was many years ago, and I ...... that time."

Later, in the description of Wusun Military Division, Ding Hao also knew the reason for it, and where the most important classics were the [Heart of Heaven and Earth] information.

"So, this book is in the royal arsenal?" Ding Hao asked rhetorically after listening to it.

Wusun Military Master nodded and said, "Well, I did enter the royal arsenal and saw this book in that year. ”

"It turned out to be ......in the royal arsenal" Ding Hao bowed his head and did not mention this topic again, as if he had brought it up casually, and he didn't say it again after talking.

Even if he was a smart person like Wusun Junshi, he didn't notice anything abnormal about Ding Hao.

The two continued to talk.

"It's getting late, I should go back too......"

"Slow down!"

After another two hours, the Wusun military division finally got up and left here under Ding Hao's congratulatory gaze.

"Hmm, human pet, that book seems to be our only clue!" "After the Wusun military division left, Evil Moon, who had been lying on the bed, yawned, and suddenly spoke.

Ding Hao nodded: "Well, it seems that only by going to that royal arsenal and taking out that classic book can we know the clues of the [Heart of Heaven and Earth]." ”

"Just, do you know where this royal arsenal is?" asked Evil Moon with a wide wink.

"Don't worry, I knew where that royal arsenal was. Ding Hao smiled slightly.

"Since you know, that's fine, don't disturb Meow's rest, Meow is going to sleep......" said Evil Moon, who opened her mouth to reveal her little pink tongue, and then lay down again, and fell asleep like this.

"This fat cat, he can really sleep ......" After a wry laugh, Ding Hao came to the window in a few steps, looked at the sunset outside, and muttered: "Royal Arsenal!"

......

Although he knew that the classics in the royal arsenal had the news of the [Heart of Heaven and Earth], Ding Hao did not act immediately, but spent a few days quietly in the prince's mansion as usual.

It wasn't until three days later that Ding Hao took action.

After instructing the evil moon a few words, it turned into a wisp of breeze, and Ding Hao's figure disappeared into the room.

Without attracting anyone's attention, he left the prince's mansion and flew in a certain direction.

Ding Hao's body was like the wind, running left and right in the [Nine Spirit City], like lightning, quickly sweeping through many streets.

Many pedestrians walked down the street as usual, only feeling a wisp of fresh wind blowing, and did not notice that someone had just passed by.

This is true even for some people who have cultivated to a high level.

Soon, Ding Hao entered the [Nine Spirit City], the most heavily guarded palace.

This is where all the high-level leaders of the [Nine Spirit Clan], including the patriarch of the Nine Spirit Clan, who cultivated to reach the eternal realm, stayed.

A team of Ouchi guards walked neatly and regularly along the long and wide, intricate bluestone roads, patrolling.

Although these Ouchi guards were highly cultivated, they didn't notice that someone had quietly infiltrated the palace and was rushing to the royal arsenal.

Wander through winding walkways, through tasteful pavilions, and past splendid palaces......

A wisp of fresh air did not breathe, did not make any sound, and constantly passed through the palace.

In the end, Ding Hao finally came to the destination of this trip - the Royal Arsenal.

Here is a palace, carved dragon and phoenix, lifelike, the entrance of the hall is placed a three-person high bronze tripod.

On the top of the red vermilion lacquer gate, there is a black gold silk nanmu plaque, on which the dragon flying and the phoenix dance are inscribed with four big characters [Royal Arsenal].

"Found the royal arsenal, huh, that's ......" Ding Hao, who was hiding, suddenly had a smile on his face when he saw this scene, but he quickly stiffened.

Just because--

Around the palace, although there are no guards guarding it, it looks very ordinary, but with the palace as the center, on the ground within a radius of nearly 100 zhang, it is a dazzling and intertwined pattern, and there are grooves at the edges, which contain the best stones.

In the heaven and earth there, there is a forbidden force, and it seems that as long as you step close to the palace, you will be imprisoned by this force.

Formation!

It's a formation!

"No wonder there is no one guarding here, it turns out that there is a formation, I don't know how strong this formation is......" Ding Hao's eyes condensed slightly, his mind moved, released a wisp of divine consciousness, and slowly probed towards this formation.

Touching the formation and dipping into the lines, Ding Hao slowly probed, not daring to go too far.

After a while, Ding Hao seemed to detect something, and his sword eyebrows suddenly furrowed, and as time passed, his brows became more and more wrinkled.
