"In the previous class, we have discussed integrals of those functions which are readily obtainable from derivatives of some functions. That method is based on inspection, which is not suitable for many functions. Hence many different approaches have been developed for finding integrals by reducing them into standard forms. Prominent among them are -

1. Integration by Substitution

2. Integration using Partial..."

An obese middle-aged man spoke in a monotonous voice without even looking at the students as he chalked examples on the blackboard. This kind of lesson reminded Aditya why he had loathed going to school in the first place. He did not like sitting in one place, without moving, while being subjected to long hours of teaching. He felt entirely stifled at that time. But now, he had neither the patience nor the time to do this.

He had two small patches with wires attached to his pinky as he worked on his mobile. He was witnessing Tya's hacking skills. He was currently hacking Pakistan military's intranet. It was quite easy for Tya to bypass Pakistan's firewall, security nets and authentication requirements. It was not that their protection was weak, but the fact that Tya was unstoppable. Aditya was sure that with some practice Tya could hack into military databases of US, Europe and other developed countries.

One would be mistaken if they thought that Aditya was using just a smartphone to hack. Tya had already sent malware packages into computers and mobiles of many countries. This malware enabled him to control these devices remotely without the owner realising that someone was utilising their device's computing power. So, in a matter of few hours, Aditya had successfully employed the processing power of tens of thousands of machines for his use. His mobile just had to do the work like how a CEO of a multinational company works, i.e. give orders.

The rest of the work is taken care of by other computers. Tya was currently controlling the 'SahasraQ' supercomputer in Indian Science Institute, Bangalore, to do most of processing and computing for him. It was a supercomputer with smaller capacity (1,244 Tflops/sec), which was enough for him. This supercomputer proved to be active support in these trials.

All the knowledge and input from the computers all over the world was processed, categorised and stored in 'SahasraQ'. Aditya could retrieve the information whenever he needed. He did not utilise the computers in his control to their utmost capacity, which might cause unnecessary suspicions. That was the reason that he employed so many systems so that the individual load would be quite insignificant.

Aditya felt that Tya was like a future version of the supercomputer or a quantum computer. He managed all the work in the matter of a few minutes.

So, even if Pakistan Military's IT wing detected that their system had been hacked into, the result of their diagnosis would be quite shocking. It would show that almost all the countries in the world were working together to break into their systems. Tya had weaved a highly complicated web of networks so that no one could track him down. Aditya found many confidential links between Pakistan's military and some organisations in other countries like China and the US. He ignored them as they were irrelevant to him.

The primary goal of his hacking was to see if the idea of directly connecting Tya to the real world was feasible or not. By removing Aditya has a medium, Tya could finally utilise his potential effectively. Aditya could also save a lot of his time and invest himself in other things while Tya could help him share his work. But there was a small issue. Tya could send signals through nerve cell manipulation, but he couldn't receive information in the same way.

Tya could write all kinds of programs and software but could not receive the data. Aditya was thinking of making a device which transforms the vast amounts of data into binary code. This binary code is then transmitted in the form of electrical charges (small amounts – not lethal) into a nerve in his hand either superficially or through acupuncture needle insertion. He was still working on it.

If this theory was implemented successfully, then Tya could effectively do all he wanted without having to rely on Aditya. He could learn petabytes of data all by himself, through these electrical stimuli. Aditya did not need to read for Tya anymore. Tya would probably be the happiest as he was always curious about everything. Aditya would also feel elated as he would possess a database of all the information available on earth.

"Got it," Tya's cute voice rang in his mind as two documents appeared on his mobile screen. This document was the detailed list of spies and sleeper cells planted in India by the ISI (Inter-Services Intelligence) of Pakistan. Aditya did not glance at them as he forwarded this list to his elder sister Saira. This was the second goal for choosing Pakistan's military intranet as his target. He wanted to help his elder sister Saira in her work.

The second document was a list of Indian politicians and administrators. These people worked alongside with Raipath Family to create pockets of undeveloped areas in India where the law couldn't reach. These bastards were the reason that Maahi was forced to commit suicide in the future of the 'dream world'.

Of course, Aditya was not going to let it repeat. Tya's algorithms were far more advanced than those created by Maahi's companies. So it took an hour before all the details were in Aditya's hands.

'Rudra' would be paying a visit to those people who were in Bangalore, tonight. He needed quite a bit of money for his plans. These corrupt politicians and the Raipath family would be treated as his cattle from which he could milk whenever he needed. He did not have the idea of turning them to the Indian government any time soon. He wanted to destroy them with his own hands.

Of course, he wouldn't let them continue exploiting people anymore either. He wanted to make them experience sleepless nights, with their hearts filled with fear and regret. They should not have the courage to read a newspaper in the morning or watch the morning news for fear of seeing or hearing their names in the headlines.

Aditya had plans for utilising these undeveloped pockets for his objectives. These places did not have law and order and minimal access to the government's facilities or welfare schemes. Most of these pockets survived through conventional farming. These places were ideal for Aditya who wanted absolute privacy and secrecy. These places where there was no proper telecommunication, let alone the internet, how could 'that' organisation know anything about them.

So, these places became an essential resource for his plans. He would become the government for these people. He would take care of them, educate them and introduce them to a better lifestyle. In turn, they would become his first group of helpers in his endeavours to rescue his parents. It might be unethical for thinking this way, but Aditya did not have a choice in this matter.

In the end, he was a selfish person who wanted his close ones safe before he thought of any greater good. If it was Saira, she would never do such a thing. For her, the country came first. But Aditya was not made that way.

A bell sound brought Aditya out of his contemplation as he removed those patches on his finger and put the device back in his bag. Kranthi woke up slowly while Kumari remained asleep. Aditya felt that this mathematics lesson was the most effective lullaby. The teacher was very cooperative, and he did not even glance at students. The teacher seemed to have taught mathematics to the 'blackboard', itself. These are the people who work to earn a living.

Aditya's pinky felt numb due to hours of continuous electrical stimulation. He lightly massaged his finger as he stretched himself and walked towards Kumari. She was the only one who dared to sit on the boys' side while the rest of the girls occupied the other end of the classroom.

Aditya shook her thin, delicate shoulder and attempted to wake her. Drool could be seen flowing from the corner of her mouth and decorating the mathematics notes. Kumari opened her eyes lazily to look at Aditya and went back to sleep again.

Aditya rolled his eyes as he said to Kranthi in a loud voice, "White Buffalo, let's go. I heard that there's a special food item in today's menu in the canteen."

"There is?" Kranthi asked doubtfully. When he saw Aditya's stare, he got the point and nodded, "Oh, what item is it, Adi?"

"What else can it be? It is Aloo Bonda (fried dumplings with potato stuffing)."

"Aloo Bonda?" Kumari sprang from her seat as she looked at Aditya with bright, shining eyes.

Aditya grinned as he wiped her drool with his handkerchief as he said, "I said that I heard about it, I am not sure whether if it is true or just a rumour. Come, let's go and find out."

"Adi, you jerk," Kumari aimed her leg at Aditya who dodged it easily. She knew that Aditya said it so that she would wake up.

She was about to go back to sleep, but Aditya held her firmly as he declared, "Friends, yesterday was my birthday. I am sad that I did not get to celebrate it with you guys. So, as a compensation, I have decided to host a small party in our school canteen. I don't want to see anyone taking out their lunch boxes. The bill is on me." Aditya had spent his whole birthday with Maahi, yesterday, and was not available to anyone else.

Everyone cheered when they heard Aditya's words. Kranthi came near Aditya and said excitedly, "Adi, after those 'IC' students (International Curriculum) came, our school administration built a new cafeteria. Why don't we go there, instead?"

Aditya shrugged as he did not have any particular preferences. Before he could modify the venue, Kumari held his hand and shook her head. She said, "that place is costly, no one from our class had ever stepped into that place. Usually, only those 'IC' students hang around there. Only some girls from our class have been invited." Kumari glared at Kranthi who rubbed his head sheepishly.

Aditya removed Kumari's hand as he shouted, "There is a change in the location, the party is in the new cafeteria." Maahi had given him a new bank card yesterday. Even Aditya did not know the amount of money it contained.

He had his own money as 'Ishaan' or 'Rudra', but he couldn't use it now. Using Maahi's money made things so much easier. Kumari knew that Aditya had money. But she still thought he did not have to spend so much. Kumari did not dissuade Aditya again as she quietly followed him along with Kranthi.

The cheers from Aditya's classroom could be heard reverberating all over the school building as the crowd rushed towards the new building in the distance. Aditya followed as he felt his heart lighten up when he heard these cheers and saw the happiness reflected on these people's faces. Aditya conversed with his friends about simple things like film celebrities, music albums etc. All the stress that had been built up in his heart seem to evaporate.

Aditya noticed that Kumari's face become melancholic suddenly as she looked at someone in the distance. She was not looking at the person but at the box that he was carrying. Aditya looked askance at Kranthi as he gestured at Kumari.

Kranthi sighed as he said, "our school got huge tons of money as donation after these IC students came. So our school administration planned to build many new facilities which we didn't have before. Archery Academy was one of those. It was set up in the ground, near the Banyan tree. Kumari had gone for archery selections. She was attracted to this sport very much."

"The coach, who presided that selection, also praised that Kumari had the perfect form and potential for professional archery. But you know that Kumari's family is middle class and they want a stable career path for her instead of this risky venture. It's not like Kumari is a genius in studies so that her parents could agree to spend some of her time on archery also. They did not agree to her request, and also, learning archery is not exactly cheap, right?"

Aditya realised that the box was an archery equipment kit. He looked at Kumari and did not speak about it as it was not the right time. Aditya observed that many new facilities came up around the otherwise old buildings. Many of them were under construction. He saw that the cafeteria place was just as luxurious as he had imagined. It was filled with 'IC' students who wore different uniforms.

Aditya's classmates rushed in excitedly and started ordering all kinds of food. Aditya warned his friends not to waste any food and asked Kranthi to look after everything as he handed the card to him. He had a crucial thing to do now.

Aditya awkwardly laughed as he went near Bhadra and Jatin who were standing in the corner, cracking their knuckles. He had to give them a valid explanation for not joining their batch and accept their punishment.
