The first floor of Tongtian Tower tests a cultivator's attacking power, while the second floor tests their defensive capabilities.

  Masters who enter the second layer of the passage usually hold the Heavenly Command in their hands at all times, and once they encounter a danger that is difficult to defend against, they will activate the Heavenly Command in the first time and leave the Heavenly Tower.

  Zhao Di reappeared in a crimson passageway after passing through the archway leading to the second floor of Tongtian Tower.

  This passageway is slightly wider than the first floor, about three feet wide, and finally doesn't feel so narrow, but there are still powerful anti-aircraft and anti-spacecraft restrictions.

  Zhaodi's body was wrapped in a purple aura, and under the cover of four puppets in front, back, left and right, he strolled leisurely, which was quite pleasant.

  These four puppets, each holding a shield-like defensive spirit tool, protected Zhao's land tightly.

  This passage initially seemed calm and peaceful, but every time Zhao Di walked to a place, the light walls on both sides would shoot out flames from various angles, as if they had eyes, directly attacking Zhao Di.

  The scene was somewhat like refining equipment, with flames spewing out from all sides, burning on the refining materials or cauldron.

  Who would have thought that Zhao Di, who had refined countless equipment, would now find himself in a predicament of being refined by fire.

  Less than a mile away, Zhao Di's face was no longer relaxed and comfortable!

  He found that as he went deeper, the fire pillars shot out from both sides of the light wall became thicker and more powerful.

  The high-level spiritual stone inlaid on the puppeteer's instrument was also being consumed at a speed visible to the naked eye.

  What's even more frightening is that the fire pillar's attack on this road is uninterrupted, whether he stops or moves forward and backward, the light wall on both sides will accurately spray out the fire pillar to strike him. Under this continuous attack, the monk's sustained defensive ability has extremely high requirements.

  Zhao Di looked ahead and still couldn't see the end, at least it seemed more than ten miles long.

  If he didn't have a puppet and high-grade spirit stone, but relied on his own spiritual power to support the defensive magic treasure, it's really hard to say whether he could walk out such a long distance.

  Fortunately, he had prepared a large number of high-grade spirit stones and wouldn't mind using some up. However, Zhao Di and the puppet also quickened their pace to avoid wasting too much time and letting the puppet suffer more damage from attacks.

  After running for several miles, the high-level spiritual stones inlaid in several defensive spiritual tools were about to exhaust their spiritual power. Zhao Di had no choice but to personally offer a pure Yang shield to protect himself, and then replaced a batch of spiritual stones at the fastest speed.

  In just this moment, Zhao Di clearly felt that he had consumed a lot of spiritual power in defense.

  After spending an hour, he quickly walked out of the crimson passageway, which was about 30-50 miles long. Along the way, he had to replace his spirit stone twice!

  Zhao is now in a relatively safe place, a flat area of tens of meters in diameter. In front of him, dozens of meters away, there is another passageway flashing with dazzling red light. Just from the heat wave that came rushing over, this passage can only be even more treacherous.

  Zhaodi took a few light breaths, and felt that the density of spiritual energy here was quite good. It seemed that this place was specifically for cultivators who had passed through the first passageway to meditate, repair and recover their spiritual power.

  This also made Zhao Di further confirm that the next passage would be even more dangerous, otherwise there would be no need to leave a rest stop like this between the two.

  It's highly likely that Qian Ji Zi, who built this Heavenly Tower, thought that even a strong Jindan stage cultivator wouldn't be able to pass through these two places continuously.

  Unfortunately, Feng Qingyun only knew the general content of the first four levels of assessment, which were attack power, defensive power, mental endurance and physical endurance. As for the specific content of each assessment, it was different every time and for each person, so Zhao Di couldn't make any special preparations based on this information.

  Apart from this, Feng Qingyun knew that the Tongtian Tower was indeed a seven-layered difficult pass, and it was certain that Qianji Zi's unique treasure and kung fu were all in the Tongtian Tower, including the later layers of kung fu in the "Nianshen Jue".

  The great elders of the Qianji Gate have always remembered this "Nianshen Jue" method, and even the reappearance of "Nianshen Jue" is considered to be the moment when the Qianji Gate will flourish again.

  Qianji Zi, why didn't he leave all the gongfa in Qianji Gate? This is a question that even Feng Qingyun cannot answer. He can only roughly speculate that perhaps there was no suitable candidate to inherit this gongfa within the school.

  Feng Qingyun entrusted Zhao Di with the sect's mission, which was to go through as many levels as possible and see if he could find any clues about the "Nian Shen Jue". If Zhao Di obtained the "Nian Shen Jue", apart from being able to cultivate it himself, he had to leave a copy for Qianji Gate.

  He gave Zhao Di a Tongtian Order and told him all the experiences of his visit to Tongtian Tower and all the secrets related to Tongtian Tower in Qianji Gate, just to make this deal with Zhao Di.

  As for other treasures obtained in Tongtian Tower, Feng Qingyun didn't mention them, and Zhao Di would naturally take them all without hesitation.

  So Zhao Di also felt that this task was very beneficial to himself and readily agreed.

  His "Mind Divine Technique" was only a little bit away from completing the second layer, and at this time he already felt that his divine sense had not only become much stronger, but also grasped many small tricks for using his divine sense, which made him look forward to the "Mind Divine Technique" even more.

  So, although he didn't know what other dangers lay ahead in the next passageway, Zhao Di still had to charge forward.

  He himself was shielded by a pure Yang barrier, wrapped in a thick layer of purple energy. The four puppets still surrounded him, protecting him, as he held the Heavenly Command and slowly walked towards the passage.

  He walked out of the city with great care and did not encounter any attacks at all.

  However, he clearly felt that the temperature around him had risen a lot, and even with the obstruction of the mixed yuan air, it was still unbearable. Zhao Di simply released the Ice Wind Python, letting it add a thick layer of cold air to itself, which made it suddenly much cooler.

  Suddenly, a red light flashed, and more than a dozen flame-shaped single-legged fire crows flew out of the light wall, making a hoarse "ga ga" sound. When they saw Zhao Di, they rushed towards him with their fire-spewing eyes.

  In this scorching environment, any fire-attribute attack will increase its might. This lone Fire Crow is probably at the level of a late-stage Foundation Establishment cultivator, but in this environment, its destructive power should be comparable to a full-force strike from an early-stage Core Formation cultivator.

  If these fire crows were to get close to the puppet and self-destruct at the same time, the high-quality spiritual tool in the puppet's hand would definitely be blown into powder in an instant because it couldn't mobilize more spiritual power to defend itself.

  Zhao Di Zhang spat out the Dream Lure Sword, transforming it into a three-foot-long purple sword that floated in front of him.

  "Split!" Zhao Di lightly spat out a word, the purple sword instantly transformed into three identical sword shadows. However, these three sword shadows split again, forming nine purple sword shadows.

  Nine sword silhouettes welcomed the Fire Crow's thrust, each driven by the power of Chaos, thus having a certain restraining effect on the Fire Crow's pure Five Elements spiritual energy.

  As expected, each and every one of the Fire Crows let out a pained cry as they were struck by the sword's shadow, transforming into tiny red lights that returned to the two light walls on either side.

  A few stray Fire Crows also crashed into the puppeteer's shield, a Spirit Artifact in his hand. With a loud "Boom", although it shook the artifact violently, it was still defended against without any damage.

  This sword shadow technique, Zhao Di had only mastered the first two layers of transformation, and could create nine sword shadows. Each sword shadow could exert 20% of the power of the original sword, so once this technique was used, it was equivalent to increasing his attack power by nearly tenfold.

  If he had a deeper understanding of Sword Shadow Technique, he could continue to create twenty-seven or even eighty-one sword shadows. Although the strength of each sword shadow would decrease significantly, the overall power would increase greatly!

  Zhao Di continued to move forward, and soon encountered another batch of Huo Ya's attack, only this time the number and power of the Huo Ya were even more terrifying. Zhao Di relied on his puppet and sword shadow, and completely resolved them all.

  At this time, there were also many monks fighting in the corridors of the second floor.

  Lin Zihuan, dressed in a white skirt, was using a white silk handkerchief made of unknown material to change into several meters in size, wrapping herself up tightly. The golden light blades that shot out from the two side passages were all intercepted by this handkerchief without any effort. Under the cover of the handkerchief, Lin Zihuan stepped forward lightly, even more relaxed than Zhao Di.

  Square-faced Zhang Beichen was walking on a icy path, using a black tortoise shield to protect his back, and holding the Mountain Splitting Whip to continuously smash the incoming ice cones. However, the ice cone attacks were too dense and continuous, and soon he was somewhat exhausted.

  But this man's surname is very strong, and instead accelerated his footsteps, making the broken mountain whip dance into a stream of yellow light, covering up the danger in front of him, while the Xuan Gui shield protected his back. After such a frantic charge, he actually broke out of this icy path and arrived at a flat area of several dozen square meters. Although there was still another icy path waiting for him to conquer dozens of meters away, at least now he had a chance to catch his breath.

  Dahan had just made a fierce charge, his arms and legs were pierced by ice cones in seven or eight places, bleeding all over. He hastily took out several talismans to stick on himself, stopping the bleeding and meditating to recover the greatly depleted spiritual energy.

  An old man dressed as a Taoist, in the late stage of his life, was forced to activate the Heavenly Order and leave the Heavenly Tower when faced with a wave of extremely violent giant stone smashing.

  A demonic cultivator, under the cover of a swirling black aura, attempted to force his way out of a passageway shrouded in lightning and thunder. However, halfway through, several thumb-thick bolts of lightning dispersed the dark energy, striking him with a wrist-thick bolt of lightning that appeared suddenly. Before he could even activate his Heavenly Order, he fell to the ground, reduced to a charred corpse.

  But Zhao Di also encountered some unexpected trouble when facing the last wave of attacks in this aspect.
