<h4>Chapter 628: The Three Illustrated Books, the Powerhouses of the Past Era! Part 2 Trantion</h4>


    There were hundreds of ores that could only be found in the wastnd.


    A variety of magical and unusual functions made up the content of the entire illustrated book.


    Under the light, Su Mo felt overwhelmed, and his eyes shed with excitement!


    Besides everything else, the value of the two illustrated books alone was worth more than the harvest of exploring a small ruin.


    Not to mention there was an additional third illustrated book.


    ‘This is... an Encyclopedia of Shelter Construction?


    ‘Such a thing existed?’


    Su Mo was immediately taken aback as soon as he saw the big words on the book.


    Almost everyone would have a different opinion regarding shelter construction!


    Some people took the safest route by building their shelter in the mountains, especially by creating a space under them for ultimate protection.


    Some chose to y slightly safer, like Su Mo, who built his shelter underground, then slowly increased the number of floors through different methods to finally form a multi-level underground shelter.


    Some chose to be a bit bolder by building their shelter on the ground, mainly to be used for sleeping as they spent most of their time seeking opportunities outside.


    Some of the others were rather brave and wherever they stopped was their shelter. The sky was their nket, and the grass was their bed.


    All these different choices of shelters would vary depending on one’s character.


    Person A’s shelter was a safe haven to him but might be worthless in the eyes of Person B, and thetter could point to countless loopholes everywhere.


    Person B’s opinion about the best shelter might also be garbage to Person C.


    Out of curiosity, Su Mo instantly turned to the first page and tried to gain insight from the table of contents.


    ‘Three chapters. Underground shelters, ground shelters, and mobile shelters.


    ‘That’s reasonable.’


    The book included the author’s experience as he traveled in the wastnd, seeing therge or excellent refuges.


    In order to prevent disagreement and disputes, the author made a clever decision to divide the book into three categories to cater to the corresponding audience.


    Su Mo had a littlepetitiveness in his heart as he opened the underground shelter section of the book.


    The first thing that caught his attention was the most majestic and spectacr underground shelter that the author had seen during his travels.


    It was a massive underground building that stretched 80 meters underground.


    The overall building structure was made of cement and steel bars, the middleyer was wrapped with heavy energy-absorbing iron stones, and the outermostyer was even heated instion and cold instion treated.


    Regardless of its internal structure, the external structure alone was worthy of the word “outrageous”!


    Inside, for the stability and rigidity of the underground building, the 80-meter building with a total of 48 floors consisted of numerous densely packed rooms that made Su Mo dizzy looking at the drawing.


    ‘This…Who in the world is capable of building such a terrifying underground facility with manpower?’ Su Mo was stunned as he read through the description.


    He turned the pages, went through the schematic illustration of the underground and shelter, and was utterly in awe.


    In the wastnd, everyone started from scratch.


    Su Mo only had a tortoise shell that they could utilize in the early days and an ordinary underground shelter with one floor.


    The system’s upgrade was the bottom line. After four months, Su Mo still felt that building a shelter had a long way to go.


    He could not rush it.


    There was no use in rushing it either.


    Without advanced infrastructure abilities and sufficient infrastructure skills, the difficulty of underground construction was simply overwhelming!


    ‘There are still a lot of mysteries of the wastnd that I am unaware of. This is impossible to achieve through manpower alone!’


    Although the underground buildings were ranked, they were subjective by the author of the illustrated book.


    For example, the equteral triangle shelter in sixth ce seemed weaker than the five that ranked before it in terms of stability and construction difficulty from Su Mo’s perspective.


    Su Mo came to thest page of the book and saw the 100th underground shelter that was listed.


    At a nce, he immediately understood that it was ten times stronger than his current underground shelter by more than a hundredfold!


    The two were onpletely different levels.


    ‘They’re so strong! It would take me two to three years to enter the top 100, even with the system’s help!


    ‘These people were probably the powerhouses and longest-living people of thest elite batch of people.’


    The schematic illustrations of the top 100 underground shelters each had a high reference value and could widen Su Mo’s vision of shelter constructions.


    Countless ideas regarding the construction of the underground shelters popped up in Su Mo’s mind almost immediately.


    He was excited to realize his ideas in the New World.
