When Tang Xuan put some spiritual Qi in the glass slab it shined and a pattern made of of shining lines and runes like symbol appeared on it then it started to attract the spiritual Qi in the surrounding towards it and in few seconds the Qi density around him increased by several folds

Tang Xuan was very surprised because he never saw something like that

'This tool has the same effect as a 6th grade Qi gathering array incredible' (Tang Xuan)

'Good these are the prototypes i made while practicing Array Circuit Tech to think they will come in use here' Rex thought as he looked at Tang Xuan's surprised expression

Rex made all these spirit slabs when his soul strength had increased and he was trying to make more complex and high grade arrays using Array Circuit Tech

Tang Xuan then tried to use another spirit slab, this time the spirit slab absorbed a whole lot of Qi compared to the previous one then three sword made of Qi got condensed in front of Tang Xuan and he felt like he could easily control these swords as long as the spirit slab was in his hands

"If used correctly then one can even injure a Human Venerable late stage expert using this" Rex said

Tang Xuan could not hide the shock on his face when he heard it

He quickly tried another spirit slab, this time a spherical Qi shield appeared around him

"It can block a full force attack of a Earth venerable early stage cultivator" Rex explained

Tang Xuan tried all the spirit slabs and every one if it surprised him, they were like array disks but an array disk can only be used once not only that they are very costly and requires spirit stones to be activated furthermore he could not figure out the weakness or the way used to make these spirit slab

"You should already know that how precious they are that's why my requirement has also increased" Rex said with a smile after he saw that Tang Xuan has checked all the spirit slabs

"Haha.. off course you can increase it i won't lie to you i also saw these things for the first time and i am interested in the trade, i am Tang Xuan may i know what is the name of the fellow cultivator" Tang Xuan suddenly laughed and said

"I am Ye Tian.. okay now can we trade" Rex asked a little impatiently

"Whats the hurry let's have a small talk first, i will be straight forward if you can tell me where did you get these things or who made them then i will give you all the things on the list for free further more i will give you a 50% discount on all the things you buy from here in the future… how about it?" Tang Xuan asked with a smile

He wasn't worried about Clin listening to their conversation because if Rex agrees to his request then they can just talk using Qi messages

Rex made a reluctant expression and sighed

"I agree but you won't go back on your words would you" Rex said

"I never go back on my words" Tang Xuan assured Rex

"The potions from earlier were made by me and these spirit slabs are the toys my boss Shadow Lord made in his free time and yeah don't ask me to show my flame my boss didn't allowed me to do it" Rex didn't even bothered to use Qi transmission message and directly said it

After hearing all this Tang Xuan's expression was weird, it wasn't about that he didn't believed what Rex said but it wasn't the answer he was looking for

"Wait old man you aren't thinking of going back on your words give me back my potions" Rex gave a suspicious look to Tang Xuan

"No i don't have such intentions.. what i want to say is.. can i meet this boss of yours in person and just saying a name doesn't prove much because i never heard of that name too… after all its not like i can ask you to take an oath just to prove that" Tang Xuan said with a smile

'This sly old fox… he is indirectly asking me to take an oath to prove it to him.. taking too many oaths is never a good thing it can affect the Dao heart that's why he knows i will not take an oath and he don't need to give me all these things for free' (Rex)

"Old man do you think my boss will himself come to this shop for such small matter.. You don't even trust me on such small things, boss always saw that we can't do business without trust… sight its a shame but its alright if you don't trust us then we have no fate.. okay pack things up" Rex shook his head

Tang Xuan's lips twitched

He knew Rex was doing it on purpose Rex was indirectly saying that he will never come to him to do business

Rex had already seen how much Tang Xuan liked his things so there is no way he will let him go over such things

"Hehe why is little brother so angry over such small things i was just joking off course i trust you, i will never go back on my words how about it i will give you double the amount of things you asked for and i can keeps this potions and glass slab in exchange" Tang Xuan said with a smile

'Little brother?… isn't he too fast' (Rex)

Rex was a little surprised he didn't thought Tang Xuan will go as far as to make such loss just to keep his failed products

He quickly agreed

"Why don't you come inside we can have a tea after that i can prepare the things" Tang Xuan said

"Thanks for the offer but i am fine here.. you see i am in a little hurry" Rex politely declined

Tang Xuan didn't asked anymore, he went inside and came out after few minutes he then took out a storage ring and gave it to Rex

Rex thanked him then he left the alley with Clin

"That's your fees and a little bonus" Rex gave a storage ring to Clin

Cling looked at the storage ring.. he only needed three low grade spirit stone so he was surprised by the storage ring, when he checked inside he saw more than 100 low grade spirit stones were scattered inside it

He was shocked when he looked around he found out that Rex had already disappeared

On the other side…

Rex was heading towards Misty Maze Forest

'I cannot make a lot of potions or conduct experiments at the inn, that place is too small for that… its better to do these things in the forest and as far as i know the king of forest won't bother me as long as i don't enter the inner zone of the forest' (Rex)

When Rex reached the forest he found a secluded area and led few arrays for protection just in case

'Geokinesis' (Rex)

The shape of the ground in front of Rex changed and in less than a minute a big building was formed in its place

Rex's psychic abilities power also improves with his strength that's why he didn't needed to put much efforts in things like these anymore

Rex entered the building

The whole building was mostly made of big halls, so Rex just chose one of those hall to make potions

After about one hour….

A huge red bubble was floating above Rex's head

Rex divided it in many parts and filled the empty bottles around him

'Now that we are done with these thing lets get to the main business' Rex walked to other hall and took out the dead bodies of the people of Monster Hunting Sect he killed earlier

Rex then took out a pair of transparent gloves he made from a fiber similar to plastic

[You want to study their bodies, you may be a doctor but not from biology]

'So what about it even if i had done biology on earth it will still won't be that easy because these guys are not same as normal humans on earth either.. they have spirit root, dantian and there are also many different species here for example Demi-Humans

Last time i had to choose one occupation for the lack of time and money but its not the same here

And I have Reverse Engineering talent it can at least help me study the bone structure, nervous structure… etc and on earth the doctors could even transplant organs when needed so maybe we can also become capable enough to transfer the spirit root of one person to another in the future' (Rex)

Rex said as he picked the body of one man and put it on the stone table beside him

[You may be the first person who started killing then dissecting to become a doctor]

'Its alright everything has a first time' Rex said nonchalantly as he took out a dagger and started dissecting the body
