After Zhang Shouyu heard Xiao Feng's promise, he was silent for a while, and finally gritted his teeth and agreed with Xiao Feng's statement.

Xiao Feng also launched a poisonous oath against the Lang Evil God in front of Zhang Shouyu.

Although Xiao Feng didn't know which great god the Lang Evil God was, cultivators, especially cultivators, still attached great importance to their oaths.

Cultivating is to obey the orders of heaven, at least in some behaviors, they are more inclined to the way of heaven, so all cultivators, including Xiao Feng, believe that there is a heavenly principle in the underworld.

Therefore, they are generally very cautious about swearing poison and will never say anything. And once you swear a poisonous oath, you will do your best to complete it.

Of course, with Xiao Feng's always cautious character, the oath will not be issued randomly, and he stated in the oath that if he can't avenge the Zhang family now, he will come back to carry out the oath one day.

This can be regarded as buying time for Xiao Feng to fulfill his promise.

Seeing that Xiao Feng had sworn a poisonous oath to the Lang Evil God, Zhang Shouyu did not hesitate any longer and informed Xiao Feng of the whereabouts of the Tianhe Dingshu.

This Tianhe book is hidden in the Zhang family's mansion, and the place where Xiao Feng is located is the door of the Zhang family.

When Xiao Feng heard Zhang Shouyu say the whereabouts of the book, he was also impressed.

The ancestor of the Zhang family actually hid the treasure in the door panel of the gate of Zhangjiazhuang's house.

Tianhe Dingshu is in front of the gate where people come and go, which is really surprising.

Xiao Feng came to the door that was peeling off the paint in front of Zhang Shouyu, he didn't hesitate, took out a short sword, and picked it up on the door.

The material of this door is by no means ordinary wood, and the magic weapon short sword is inserted into the wood, and Xiao Feng feels struggling.

Magic weapons are different from ordinary weapons, and it is not an exaggeration to say that they are as sharp as iron and clay.

However, in the face of the wooden gate, you can feel the difficulty, which is enough to show that the material of this gate is harder than iron.

It is no wonder, otherwise the ancestor of the Zhang family would not dare to hide such an important treasure in the door panel.

After picking for a while, it wasn't until the gate was cut that Xiao Feng found the legendary Tianhe Dingshu.

This is an ordinary-looking book, the yellowed cover is very old, and the texture looks like paper, but Xiao Feng knows that if it is really paper, no matter how well it is preserved, it will have rotted long ago. This will never be ordinary paper, unless the book is fake.

With apprehension and anticipation, he turned the pages of the book, but soon Xiao Feng's face became gloomy, the faster he flipped through the pages, the more he turned back, the more gloomy Xiao Feng's mood became, and his face could drip ink.

It turned out to be a blank book, with neither pictures nor words on it.

"How dare you lie to me. Xiao Feng turned to the last page, making sure that there were no words or pictures on the book, he threw the book to the ground and looked at Zhang Shouyu, his eyes flashing with a hint of murderous intent.

The reason why Xiao Feng was so angry was mainly because he found that this was not only a blank book, but also that he used his divine sense to check it, and he also found that this book was extremely ordinary, and he couldn't see anything unusual.

It can only be said that this is an extremely ordinary blank paper book, and he is so played, how can he not be angry.

"Sir, I didn't lie to you, this book is indeed a book of Tianhe. Zhang Shouyu seemed to know why Xiao Feng was angry, and he hurriedly explained.

"Hmph, if you hadn't lied to me, what was the matter with this book. Xiao Feng picked up the blank book and shook it in front of Zhang Shouyu, and the blank pages shook open in front of Zhang Shouyu.

"Sir, I didn't lie to you, my ancestors of the Zhang family have been passed down from generation to generation, and the Tianhe Dingshu is absolutely extraordinary, and you may need some way to see its contents, but the ancestors have not passed it down, and I don't know. Zhang Shouyu said with a wry smile.

If he knew the method used, he would have taken out the Tianhe Dingshu a long time ago, and he would not have fallen to this point.

In fact, Zhang Shouyu did not confess a sentence, his ancestors also circulated a saying from generation to generation, and it was useless to take the Tianhe Dingshu.

Zhang Shouyu's father once took out the Tianhe Dingshu, and the young Zhang Shouyu had also seen it, but unfortunately he couldn't understand the subtleties in it.

If he could understand it, he would have left the Lang Evil Continent with the Tianhe Dingshu a long time ago, and he would not have fallen to this day.

When Xiao Feng heard his words, his brows couldn't help frowning, and something immediately flashed in his mind, Tianyuan Dao.

The Tianyuan Knife also seems to be a mortal thing, but in fact, Xiao Feng knows that this treasure is not bad. It's just that he doesn't know what to do.

Could it be that Tianhe Dingshu is such a treasure, if this is the case, then he really doesn't know whether it is a blessing or a curse.

Thinking of this, Xiao Feng decisively picked up the blank book, bit his finger, and dripped three drops of blood into the writing.

The hands were constantly changing, and when there was an aura between the fingers, Xiao Feng's right hand turned into a sword finger and drew towards the place where the three drops of blood were, and a quaint character was engraved on the cover.

This character is extremely obscure, it seems to be an order, it seems to be a fate, it seems to be a fate, and it seems to be a non-present. Apparently not written.

But if there is a knowledgeable person here, you can definitely see at a glance that this character is a contract to recognize the Lord's magic weapon.

As the characters gradually integrated into the book, Xiao Feng's divine sense hummed violently, and a rebounding force almost stunned him.

Xiao Feng forcibly endured the rebound of this shock, and used his divine sense with all his strength to resist the power transmitted from the underworld.

At the same time, Xiao Feng was also extremely shocked in his heart, he never imagined that this book would resist, at this moment he was sure that this book was nothing extraordinary.

After resisting for a while, Xiao Feng felt extremely tight in his chest, and a mouthful of blood gushed up his throat.

Xiao Feng's face was pale, but he still gritted his teeth, tried to squeeze out the pressure from the oppression, and sprayed all the blood that poured into his mouth onto the Tianhe Dingshu.

This will make it difficult for Xiao Feng to ride a tiger, if he finally breaks the contract with Tianhe Dingshu, he will be counterattacked, and even if he doesn't die, he will only have half a life left.

The only way to do this is to increase the contract and forcibly admit the Lord. Of course, if he fails to confess the Lord, he will be met with even greater backlash.

Xiao Feng looked at the originally ordinary Tianhe Dingshu at this moment, and he was shocked and angry.

What is surprising is that this treasure is absolutely extraordinary, and he can feel that this treasure has spirituality, as if he still has an independent consciousness, but the angry thing is that he was calculated by Zhang Shouyu, and he wants to recognize this treasure, no matter whether it is successful or not, Xiao Feng will not end well.

There is no other reason, he is just an artistic conception period, barely a painting god period, and his cultivation is far from reaching the Purple Mansion period, and he can't control the magic weapon at all.

Even if he succeeds in recognizing the Lord, he will not be able to use this treasure, and he will only end up seriously injured.

If he does not succeed in confessing the Lord, he will be in danger of his life.
