Compare to Groot and Coal, the tribulation the descendant of Greenbark Clan summon amount nothing at all. Due to the bribe he received, he even asked Blue to protect and fully absorb the tribulation lightning, which it easily perform.

He don't know if the other cultivators were afraid of tribulation lightning or they were just clueless about the benefits of bathing on it but Cole and Blue was more than happy to agree to absorb all the tribulation lightning. Not only it'll be used on its cultivation, it was also spared from the effort of controlling the might of tribulation lightning that'll baptized the cultivators.

The person from Greenbark Clan stay in the Towering Tree City for several days to stabilize the situation of the newly broke through cultivator.

Cole didn't chase them out but he don't entertain them either. After all, he want to spend his time challenging the dungeon monolith than to entertain a person that might even become his enemy afterwards.

Still, he spend some minute to converse with them. After all, they're still a guest of their city not to say that they also made an business exchange with them. Cole consider the act as post business care.

In the end, he manage to acquire some information from the other party and mainly pertain to the Imperial Martial Exchange, which the Greenbark Clan put a huge effort on.

The Imperial Martial Exchange is an event held by Heavenly Flame Empire every ten years. It was one of the once in a decade event that was already well known in cultivators society in Azure Territory.

The Imperial Martial Exchange is an event where all the sects and factions would send their disciples and exchange friendly martial discussion. In simple word, it was an event where there'll be a friendly martial battle between the factions present in Azure Territory.

The Rising Phoenix Spirit Tree Nation is just a newly established faction and Cole might not know the so called event but the other party said that he could expect that the Heavenly Flame Empire would send an invitation to him.

And indeed, just before the guest from Greenbark Clan leave, a person from Heavenly Flame Empire enter the Towering Tree City that deliver the so called invitation.

Honestly, Cole don't have the intention to participate in the so called Imperial Martial Exchange. After all, the event will be held for almost a week and should he participate on it, it means that the a week will be wasted by not challenging the dungeon in that time.

Furthermore, a week on the outside equates to almost a month inside the [Inner World]. In addition to time dilation of dungeon dive itself, participating in the martial exchange means that those will participate will lose a several months of effort!

Even Cole feel a little heartache upon thinking the possible result.

However, even if he don't want to, he has to participate. It was also a perfect way to introduce the Rising Phoenix Spirit Tree Nation to the whole Azure Territory.

Besides, it wasn't as worthless as Cole put it. He can still acquire some substantial amount of benefits.

For instance, in the early times of martial exchange, the empire will give the stage to the lower end of the power level. Which means that the start of the event will be the time where low level youths would try to make themselves shine.

Most of the participants in the early stages belongs to clans or kingdoms with weak power. The reason why they'll fight out in the martial exchange is just to publicize themselves and acquire the attention of more powerful clans, kingdoms and even the empire.

That is to say, the early part is for more powerful powerhouse to recruit young cultivator that has potential and talent.

In this part, Cole might be able to recruit several figures that could increase the number of his martial force.

In addition, the Imperial Martial Exchange invites all the factions present in the Azure Territory. It'll be a perfect chance to associate himself with other independent sects like Five Element Sect and Yin-Yang Wonderland, those who don't link themselves with Heavenly Flame Empire.

If he can't associate and make connection with them, Cole could also acquire some treasures from them if they agree on each other terms. This could be a chance for Cole to buy massive amount of cultivation method and technique that his country lacks in exchange for equivalent treasures or spiritual stones.

The environment of the [Inner World] is more than enough for cultivation. Its rich spiritual energy environment and concentration gave birth to many spiritual stones that they become mere pebble inside.

Those spiritual stones were supposed to be used by police department of the country but for now, it'll be used as exchange currency.

All in all, Cole can acquire many benefits from that socialization event. It was the thought of missed dungeon dive makes him hesitate.

The martial exchange will be held after a month. Cole have more than ample amount of time to make a decision.

Instead of dwelling on it, Cole choose to focus more on the matter on hand.

For instance, several days after assisting the descendant from Greenbark Clan, Blue recover to his peak state a day after. The latter then assist Hunter on its breakthrough to Tier-5, which was successful without a hitch.

Unlike the others, Hunter's tribulation were the same as the others. It didn't manage to summon a special type of lightning.

But this was normal. After all, Hunter didn't receive any special bloodline like Coal and it wasn't as ominous as Blood Ghost Locust Tree. Hunter is special, that is an undeniable fact, but it is by far normal compare to the first two.

Hunter's tribulation was normal and Blue only spend another day to recover from negligible negative effect from assisting someone's breakthrough.

But in the first place, Cole don't have the intention to ask Blue's assistance. After all, although he was limited by his own base cultivation, all the improvement on Blue's [Lightning of Nine Heavens Concept] were are mirrored to him through Myriads Beast Soul Branching Cultivation Method' [Soul Fruit]. That alone is enough to reduce the difficulty when he face his own tribulation.

Furthermore, his recovery ability is top notch. Blue's [Concept] ensure that he won't be killed in one shot by tribulation lightning and pair it with his ability to recover, he was confident that he'll be able to pass it without anyone's help!

Cole start to prepare for his breakthrough. In actuality, it was nothing much; it was more of adjusting his mentality. Blue's past task of absorbing tribulation lightning alter Cole's mentality but he's still worried when it was finally his turn to face not a bolt but a pillar of lightning strike!

But in the middle of his adjusting pace, another elderly Nascent Soul-Stage cultivator approach the Rising Phoenix Spirit Tree Nation.

Youths were filled with vigor and confidence that they'll be able to overcome their Heavenly Tribulation on their own. Cole already expect that he won't be able to attract a youth on his offer.

On the other hand, elderly were more wiser and was more than capable on judging situations better. They weren't as hot blooded as youth. Furthermore, their limited talent, which was indicated from the fact that they reach the peak of Nascent Soul-Stage in their old age, and lack of vitality and vigour a youth possess made elder cultivators to hesitate to summon and overcome their own cultivation.

Still, facing one's death is not easy as it seem. Therefore, Cole was extremely confident on this plan of his.

This time, the elder that approach his territory were in much better state than Lara. It was a male elder that look vigorous and more than capable of living for more decade at most.

However, the first time he meet the elderly, he was assaulted with thick scent of wine and the latter looks like a drunkard than a supposed to be expert.

Cole won't deny that he dislike the other party on their first meeting. He don't have positive opinion regarding drunkards.

But his opinion change when he heard his profession!

Just like Lara, the drunkard looking elderly who introduce himself as Win Alchl were a mediocre cultivator that focus more on their lifestyle profession than their own power. Their passion lies to their profession.

Unexpectedly, Elder Win were a lifestyle professional that was well known as Brewmaster, also known as wine maker.

Wine, just like tea, was one of those limited things that cultivators still consume and enjoy. It was one of the limited enjoyment in cultivators' dull life.

Of course, although wine were one of the things cultivators enjoy, they won't just casually consume any wine. Just like foods, cultivators would only consume things that contains spiritual energy.

This was where Brewmasters rise.

Brewmasters were those lifestyle cultivators that was capable on brewing wine from spiritual fruits!

It was unfortunate but Cole is not someone who likes wine or alcohol in general. Brewmaster sounds impressive but Cole can't appreciate the profession.

Still, Cole don't have the intention to deny the elder cultivator. After they discuss the term, there was now an elderly next in line with Lara Andres.

It is true that Cole is not a fan of wine but according to his opinion, wine were undoubtedly a lucrative business. Cole won't deny that when he hear the word 'wine', the first thing he associate it with were luxury and deluxe, things that only those with golden spoon could enjoy.

And after the sealed deal with Elder Win, Cole already intend to make spiritual wine one of the unique product of Rising Phoenix Spirit Tree Nation!

After all, with the [Inner World] and Dungeon Monolith that was capable of producing many kinds of raw ingredients like spiritual fruits and herbs!

And if the wine needs to long amount of time to brew and ferment, then he believe that Time Dilation of [Inner World] could play a massive role on this plan!

Elder Win didn't belong to any faction and he was considered a rouge cultivator. The same as Lara, if he don't encounter any fortunate encounter that could increase his life-span or gave him the chance to make a breakthrough to Void Sensing-Stage, Elder Win could only wait to naturally deplete his lifespan.

But since Elder Win already pledge his loyalty to Cole with the contract condition that he'll assist him on overcoming his Heavenly Tribulation successfully and ensure that the elder's life won't be put on peril, the matter of depleting his lifespan are not a problem anymore.

In fact, in order to ensure his doubtful heart, Cole also gifted the elder with a drop of Spring of Life, replenishing his life-span and vigor of his body. This move was to ensure that the elder won't die if a stray lightning hit it.

Unfortunately, Elder Win are already at the back of the line and it'll take time before his turn on tribulation assistance come.

Therefore, since the Elder will have a lot of free time, he immediately bring him inside the [Inner World] and create several wine house where wine will be left to ferment.

It was only then Cole learn that wine brewing is not easy as the one he knew.

Elder Win do make a wine house on his own where he left normal wine to ferment and mature.

He also create some wine using the special environment present inside the [Inner World].

For instance, Elder Win brew wine using spiritual ingredients that contains lightning attribute and ferment it in the special mountain formed by Yggdrasil inside the [Inner World] that was literally raining with lightning. It was supposed to be the cultivation spot for Blue and other future beast companion that has lightning affinity. It was a type of wine that could literally fry body and mind of who'll consume it.

The prospect of business in wine making makes Cole gave Elder Win a permission to use all the available materials and ingredients inside the [Inner World]. That includes all the spiritual herbs of varying ranks and level as well as some special ingredients like the Amber Honey of Golden Bee hive and Water of Life of Tree of Life!

In fact, the [Inner World] and benefits Cole provide to the Brewmaster makes the latter turn into loyal subordinate in an instant!

The place is like the promised Heaven for the passionate wine maker!
