Cui Heng was pleasantly surprised by the System upgrade.

This meant that as long as he charged enough value, he would be able to upgrade and gain the Immortal Cultivation Technique. He could also pay to obtain more novice perks.

Moreover, he had not expected to find an item that could be converted into System currency the moment the upgrade was completed.

What a double blessing.

Cui Heng checked the System interface immediately.

There were only two lines of words now.

[Currency: 0]

[Purchasable: Omnipotent Immortal Cultivation Package. Price: 99]

Other than that, there was nothing else.

It was very simple.

Just as Cui Heng had predicted, if he wanted to earn the right to renew the novice perks, he had to recharge enough credits to redeem the package first.

This trade was even shadier than a goose!

Cui Heng rolled his eyes, but still issued an order to the System. “Convert the currency immediately!”

Then, from his perspective, the stone slabs below suddenly began to glow with a faint silver light, then in the blink of an eye, the light disappeared.

At the same time, the number of coins on the System interface increased.

[Currency: 0.03]

Cui Heng was extremely surprised.

The items that could be converted into currency were actually these stone slabs?

What was this principle?

“Do convertible objects need to be man-made or something else?” Cui Heng frowned slightly and thought to himself, “If the stone slabs in the tomb can be converted into currency, then can the things in the tomb be converted too?”

Cui Heng was tempted.

That was because it was highly possible.

Thus, he immediately decided to open these stone slabs and enter the tomb to take a look.

Cui Heng had considered whether there were any ominous things in this tomb, such as red-furred zombies or monsters.

However, judging from the amount of currency converted from the tombstone, the tomb itself should not be of a high level.

Moreover, since it was only buried a dozen meters below the ground and there were no restrictions or formations protecting it, it meant that it was unlikely that it would pose a threat to a cultivator at the Peak of the Golden Core Stage.

After entering the tomb, Cui Heng realized that it was just as he had expected. It was not a high-level tomb.

Both the scale of the tomb and the burial items were ordinary.

The tomb had even been robbed before.

Many porcelain objects that had been buried with the deceased were knocked to the ground. Most of them were broken. There was very little gold, silver, or jewels, and most of them were scattered on the ground.

Even the coffin of the deceased had been opened.

Cui Heng walked over and saw a corpse that had been torn into pieces. There were broken pieces of cloth hanging on it. It was obvious that the grave robbers had paid special attention to it.

There were also some copper coins scattered around in the coffin. They must have been left behind by the grave robbers.

“Treasure of Great Jin?” Cui Heng saw the words on the copper coin. He raised his eyebrows and muttered, “I remember Qiqi’s country was called Great Jin.”

He took out a copper coin from the coffin and examined it carefully.

The workmanship of the copper coin was rather exquisite, and the words on it were very clear. It should have been made when the dynasty was flourishing.

On the front was the words “Great Jin Treasure”, and on the other side was “First year of Jianxing”.

Great Jin was a country, and Jianxing should be the year of the Emperor.

At the same time, Cui Heng received a System notification.

[Congratulations! You have discovered an item that can be converted into currency. Do you want to convert it immediately?]

He was silent for a moment, then nodded.

“Convert!”

In the next moment, Cui Heng saw that the porcelain, jade, jewelry, the coffin itself, as well as the copper coins scattered in the coffin all lit up with a faint silver light.

Cui Heng’s currency interface increased.

[Currency: +20]

“The upgrade package is only 79 coins away.”

The corners of Cui Heng’s lips curled up slightly as he revealed a happy expression. The feeling of gaining something was always wonderful.

At the same time, he was also wondering what the System was using to judge the value of the items for conversion.

From the two conversions just now, it seemed like they were both objects with traces of human creation. Furthermore, after conversion, the items themselves did not change at all.

Cui Heng looked around and said, “There is the least amount of copper coins converted, and the numbers are almost negligible. The coffin itself and the stone slabs are also very low in number. Jade and porcelain are the most common. The more exquisite they are, the more currency rewarded. Could it be that it depends on the level of workmanship?”

He could not be sure now. He could only make some guesses on the value of the items based on the final amount.

Finally, he looked at the copper coin in his hands and observed the words on it.

Great Jin!

This made Cui Heng think of something.

“System, is this world Jiang Qiqi’s world?”

[Respectable host! Your novice period has expired. Please recharge and upgrade to an all-rounded cultivation package. The System will continue to protect your path to Immortality!]

Money-faced!

Cui Heng cursed in his heart, and then he put away the copper coin and left this tomb.

However, he did not return to the surface, nor did he continue to sink further down.

Instead, he continued to use the Earth-Repelling Technique to roam the underground, searching for more graves.

Although he did not know the specific rules of the System’s currency conversion, he could at least confirm that burial items could be converted.

His top priority was to find a few more graves and collect the coins needed to upgrade for the package.

…

Underneath this dense forest, there seemed to be a group of graves.

It didn’t take Cui Heng long to find five ancient tombs, but three of them had been turned upside down by the tomb raiders, with only a few remaining intact.

He only converted 30 coins in total.

All five graves added up to only 10 coins more than the first one he had encountered.

Fortunately, there were many graves here.

Cui Heng quickly found seven more graves.

[Currency +0.3]

[Currency: +15]

[Currency +0.2]

…

[Currency +0.5]

[Currency +21.3]

Although most of the tombs had been raided, there were still some remaining. Cui Heng finally saved up more than 80 coins.

He was very close to obtaining the upgraded package.

After a period of searching, Cui Heng found another tomb of a considerable size. Just from the items outside the tomb, he had converted another 0.5 coins.

When he entered, he found that the size of the tomb, the number of burial items, and the rarity of the burial chamber, far exceeded all the tombs he’d raided earlier.

He even found many books and seals in the tomb.

Most importantly, it had never encountered a tomb raider before.

“Convert!” Cui Heng ordered the System.

[Currency: +58]

The gains were astonishing!

The owner of this tomb was definitely someone with an extremely high status when he was alive, perhaps even a noble.

However, even with this kind of identity, the deceased still didn’t have any special protection in the tomb.

There were only some traps.

This caused Cui Heng to feel slightly puzzled.

What effect could such ordinary traps have on powerful cultivators?

“Let’s see what’s written in these books.” Cui Heng walked to a bookshelf.

Boom!

At this moment, Cui Heng suddenly heard an explosion from outside. The tomb chamber shook violently, and the bamboo slips on the bookshelves fell down.

Then, loud laughter came from outside.

“It’s open! It’s open! Hahaha! Brothers, look! We’re rich! This is really King Lu’s tomb. We’re rich!”
