As for whether to choose the sword or sword exercises, Zhang Peng decided to wait until he returned to the secret room to have a good understanding of the two sets of exercises before making a decision, thinking that this was the safest way.

And now he was itching and couldn't wait to see what was in the next jade box, after all, the things in the first three jade boxes were extraordinary.

Thinking like this, Zhang Peng flipped through it with one hand, and received the golden pages in his hand into the storage bag.

Immediately picked up the last jade box, just like the previous three jade boxes, the jade box only opened with a flash of inspiration after his palm brushed.

Suddenly, a burst of seven-colored brilliance burst out of the jade box as the jade box opened.

"What is this?"

Zhang Peng frowned, staring at the contents of the box with a dull expression, and did not blink his eyelids for a long time.

I saw an elixir the size of an egg lying quietly in the jade box, the elixir was round and full, and it was full of seven-colored light.

A slightly sweet and rich medicinal fragrance wafted out from its elixir, making people feel clear and refreshed when they smelled it, just like the legendary elixir.

Seeing this, Zhang Peng's mind immediately began to spin rapidly, and all kinds of Danfang materials began to flash in his mind, but then he was denied one by one.

It wasn't until halfway through the ringing that he still couldn't find this kind of pill-like information in his mind.

Although this elixir looks like an elixir, it may be a ten-poison elixir.

After all, in the world of cultivating immortals, there are all kinds of possibilities, and Zhang Peng would never dare to swallow it directly like this before he didn't know the specific medicinal properties and functions.

This made him suddenly have to put the jade box on the lid and put it back in place again.

Immediately, Zhang Peng put a bunch of fiery red spiritual materials into a large jade box, and with a pinch, the stone box disappeared in place in a flash of five-colored light

Half a month later, the door of Zhang Peng's secret room opened. Immediately, his figure flashed, and he walked towards the storage cabinet.

After half a month of in-depth understanding of the two methods, Zhang Peng finally decided that it was more suitable for him to choose to practice the sword system exercises.

There is no other reason, because the more the sword system exercises, the higher the requirements for qualifications in the future.

Although he asked himself that he was no worse than anyone else in terms of understanding, his own qualifications were really enough, and choosing the sword system exercise could only be the safest way to be forced to do so.

And now that the exercises have been chosen, they have been chosen. Then the next thing is that he is going to refine his natal magic weapon, the Yan Thunder Heavenly Knife.

According to the refining requirements of the Flame Thunder Heavenly Knife above the exercises, if you want to refine this knife, you must use the three major materials of Thunder Stone, Flame Fallen Wood and Heavenly Thunder Wood as the main materials, supplemented by a large number of top-level fire attribute spiritual materials, spiritual materials, and a large number of other magic weapon refining materials to refine this knife.

At this point, Zhang Peng finally understood the name of the things contained in the jade box and what the pile of materials that exuded scorching heat was for.

The stone that emitted amazing thunder and lightning was supposed to be the Thundering Stone, and the small tree that was burning with flames must have been the so-called Flame Fallen Tree.

After knowing the name, Zhang Peng began to rummage through his own collection of classic materials, and finally found the introduction of these two materials on a jade slip that recorded the strange things of heaven and earth.

The Stone of Thunder is also called the Stone of Ascension, nothing else. In order to produce this thing, it must be the power of the Heavenly Thunder that descended from the Boundary when the monk ascended to the Upper Realm, when the passage between the two realms was connected, and it struck the object of this realm.

In order to be born under this kind of coincidence, it can be said to be a thing that can be encountered but not sought, and the value is immeasurable.

The birth of the Flame Falling Wood is also more difficult than the Thundering Stone, and Yu Jiannei also roughly made the following guesses about the birth of this thing.

To give birth to this thing. First of all, this material must grow in a place where fire spirits can be born, and must be accompanied by fire spirits all year round.

After absorbing the fire spirit qi and the earth flame essence for many years. In the end, when some fire spirits have fallen, they can absorb the fire divine essence that has collapsed in time, and this thing can only be born after the accumulation of long years.

These two materials are basically legendary materials in the current immortal cultivation world, and one of them can be seen by the world.

When Zhang Peng finished reading Yujian's introduction, he was stunned. Unexpectedly, if you want to refine the Flame Thunder Heavenly Sword, you actually need these few kinds of anti-heaven materials that are almost non-existent.

I really don't know how the nameless monk who sat next to the spirit pool collected these two legendary materials, as well as a large pile of top-grade fire-attribute spiritual materials.

Thinking about it, this should be what he was going to collect by refining the Flame Thunder Heavenly Sword or the Heavenly Sword for himself. But I didn't expect that for some reason, it ended up in that forbidden place.

As a result, Zhang Peng, who was also trapped in the forbidden land, picked up such a big bargain in vain.

Now that the two main materials of the Thundering Stone and the Flame Wood are complete, it is now the main material of the Heavenly Thunder Wood.

And this so-called Heavenly Thunder Wood Zhang Peng is very clear, and it has similarities with the Thundering Stone. That is a top-level spiritual material that the spirit plant does not die under the bombardment of the heavenly thunder, thus producing mutations and retaining the power of the heavenly thunder.

And this kind of spiritual material will grow with its years, so that the thunder and lightning in its tree will become more and more ferocious, and finally after tens of millions of years of growth, the power of heavenly thunder contained in its tree will become a legendary thunder and lightning - the thunder of punishment.

However, the power of this kind of thunder and lightning, although there is almost no unified statement in the immortal cultivation world. However, judging from the rumors of the turmoil caused by his few appearances and disturbances, this kind of thunder and lightning can almost instantly hit the Yuan Infant Stage, and the restraining effect on the evil Dao Exercises is even more amazing.

However, there are many forms of the Thunder Tree in the natural environment, and some of the 10,000-year-old inheritance masters use its characteristics to make it under the influence of human factors can also have a certain chance of formation, although the probability is not high, but there are always individual successes.

Therefore, even though the value of the Thunder Wood was far from being comparable to the two almost legendary materials of the Thunder Stone and the Flame Falling Wood, the Thunder Wood was also the top refining material in the Immortal Cultivation Realm. Its number is also rare, and it is simply priceless in its market.

Now that he is preparing to refine the Flame Thunder Heavenly Knife, no matter how difficult this material is, Zhang Peng is bound to obtain it. For this reason, he plans to buy this kind of material in the fang market for a long time, and maybe by chance, he can really collect one.

And now all he needed to do was to sell the secondary demon beast materials that he couldn't use one by one. In exchange for a large amount of spirit stones, they can be used to purchase the remaining missing part of the top-level spiritual materials for refining the Flame Thunder Heavenly Sword, and so on.

As soon as he arrived at the storage room, Zhang Peng grabbed several storage bags placed on the pitch-black wooden shelves, and then poured them down one by one, and suddenly a large number of materials, spirit stones, magic weapons and other things were all over the place.

These storage bags were obtained by Zhang Peng from the seven murderers of Shentu that he had killed, but since they were in retreat immediately after their return, they were still in the future.

Zhang Peng picked among them and found that the spirit stones in the seven storage bags added up to only one million, and there were three or four top-level magic weapons.

There were more than 20 other upper-level magic weapons, three jade slips of exercises, as well as some pills for restoring mana and healing injuries, and a piece of tattered brocade cloth that was somewhat yellowed.

There seem to be some paths depicted on the brocade cloth. But it is incomplete, as if it were a remnant of a map.

Seeing this, Zhang Peng's eyes lit up immediately, and then he took it out of the pile of debris, and after looking at it a few times, his eyebrows were raised, and the corners of his mouth showed a hint of joy.

"I didn't expect that this Shentu Seven Murderers would also have a remnant of Donghua,"

Zhang Peng muttered to himself. Immediately, with one hand, a delicate jade box flashed. Zhang Peng put the brocade cloth in his hand into the jade box, and then put the jade box away again.

In the jade box, there was still a piece of broken brocade cloth about the same size and material as it lay quietly

Then Zhang Peng put some minor monster materials into two oversized storage bags, and walked towards Fang Shi together

A year later, a man in a green cloth with a beard was refining a low-grade flying knife in his rented shop, when suddenly a low sound of Weng Ming burst out of his storage bag.

The bearded man reached out and touched his storage bag, and suddenly a palm-sized white array disk appeared in his hand. Then he looked down at the array disk, and then put the white array disk away again.

Then the bearded man threw the flying knife he had just refined on the counter, and after a few casual words to a young man in Tsing Yi in the store, he walked towards the door of the store in a turn.

Soon after, the bearded man turned left and right on the street for nearly half an hour, making sure that no one was following him.

Then he was in an uninhabited alley. In the flash of red light on his body, he once again regained a slightly dark but only twenty-three-four-year-old young face-it was Zhang Peng.

For more than a year, Zhang Peng sold nearly forty percent of the large number of demon beast materials in his hands in batches through scattered sales, thus exchanging a huge amount of spirit stones, and then he scattered a large amount of spirit stones in Fang City, and then the madness of scattering large amount of spirit stones in Fang City swept all the materials related to refining the Yan Thunder Heavenly Knife in Fang City.

Under the huge purchase of spirit stones that it had spent seven or eight million, the only material for refining the Flame Thunder Heavenly Sword was now the main material of the Heavenly Thunder Wood.

However, this main material was as difficult to collect as he had expected, and it almost sowed a sky-high price of nearly 10 million and still had no results. In desperation, Zhang Peng had no choice but to inform several large shops of his request and ask them to help him pay attention to this kind of material.

And the reason why Zhang Peng went to refine the weapon was mainly because Zhang Peng, a natal magic weapon against the sky such as the Yan Thunder Heavenly Knife, did not have the slightest intention of handing it over to others for refining, but was ready to refine it himself after the materials were collected.

However, the main materials for refining the Flame Thunder Heavenly Sword were almost all legendary existences, and he was not allowed to fail once.

Therefore, in desperation, he could only open a refining shop by himself in the market, and under some disguise changes, he became both a shopkeeper and a refining master.

But fortunately, with Xiao Ran's refining classics, under the squandering of materials at any cost, he can now smoothly refine low-grade magic weapons, as for the middle and upper grades, it can only depend on luck.

And just before, the communication tray he left in a shop suddenly sent a message that someone was willing to sell the Heavenly Thunder Wood and asked him to go over to discuss it immediately, so Zhang Peng hurriedly left the store.

But after recovering his true body, Zhang Peng didn't seem to be in a hurry, and he spared several laps in the market before walking towards a large store called Xianyi Pavilion. (To be continued......)
