Immediately, Zhang Zhongjing and Hua Tuo reflexively opened the medicine box with their other hand, took out that particularly thick syringe without even looking, and directly stabbed towards the vein in Dian Wei’s large arm. In the next instant, the needle bent...

In that moment, Zhang Zhongjing and Hua Tuo were stunned, Dian Wei was puzzled, Chen Xi and others were embarrassed, and Xun Yu and others were all frozen in disbelief.

"How could it not penetrate?" Hua Tuo looked at the needle, which had already twisted into a wave shape. In this era, the concept of injection was introduced by Chen Xi, and after Hua Tuo and Zhang Zhongjing found it useful, they vigorously promoted it.

However, due to the great difficulty of manufacturing needles, every needle required a lot of manpower input. So currently, only quite advanced doctors could perform injections, and every needle was nurtured for a long time, guaranteeing quality.

The needles used by Hua Tuo and Zhang Zhongjing were specially made, yet surprisingly they didn’t penetrate and even got bent.

"What’s this?" Dian Wei scratched his head, pinched the needle, and the hollow needle was directly squeezed into a solid one. Zhang Zhongjing was on the verge of tears.

"Blood drawing." Hua Tuo said helplessly, as his needle unexpectedly bent.

"Oh, in this state, this kind of thing can’t pierce my tough skin." Dian Wei scratched his head and said, "In this state, I can rely on exertion to endure the legion attack head-on."

Dian Wei wouldn’t say he could only withstand it head-on, anyway he indeed could endure without any defense, just standing there using his body to take a hit.

"..." Hua Tuo and Zhang Zhongjing looked at each other, with this kind of absurd defense, conventional methods surely couldn’t draw blood. As for reverting to a normal state, blood might be drawn but would have little research value, just a large-scale Zhou Tai.

"Physician Hua, for what purpose are you drawing Elai’s blood?" Cao Cao inquired.

"Research, General Dian’s blood is very valuable for research. People like General Dian who have trained their bodies to the extreme can easily combat all diseases and recover quickly from injuries, which is a trait normal people do not possess." Hua Tuo explained while stroking his beard.

"In our view, everyone’s body, on a more microscopic level, has a very high similarity, meaning everyone has the potential to become like General Dian, except the body hides it. We hope to release this potential through research." Zhang Zhongjing immediately explained.

Cao Cao and others looked bewildered, honestly completely unable to understand such profound concepts.

"Oh, Elai, draw a string of coins worth of blood for Physician Hua." Cao Cao didn’t understand Hua Tuo and Zhang Zhongjing’s words, but as long as there was no danger, he was still willing to support it.

Dian Wei nodded, then pulled out his small halberd, ready to slash his wrist.

"If General Dian doesn’t mind, it’s better to use this." Zhao Yun, who had been watching the fun, spoke up. Dian Wei’s one slash would clearly leave a big wound.

In the conversation, a metal-glossy syringe appeared in Zhao Yun’s hand, made of pure Inner Qi. Playing it so smoothly, it was only Zhao Yun in the world today. Speaking of which, since Zhao Yun underwent the Eight-Rotation Shattering, the Inner Qi’s sheen had gained more metallic texture.

Zhao Yun handed the large syringe to Hua Tuo. As soon as Hua Tuo got it, he realized something was off and glanced at Zhao Yun with a hint of curiosity. However, compared to Zhao Yun, who could always be researched, Hua Tuo decided it was better to draw blood from Dian Wei.

The syringe made of pure Inner Qi by Zhao Yun didn’t look vicious, yet when Hua Tuo got his hands on it, he easily pierced into Dian Wei’s vein. The watching military generals weren’t naive, no one besides Zhao Yun could turn the legion attack into this shape.

While drawing blood, Hua Tuo began analyzing with talent, but quickly noticed something was wrong. Zhang Zhongjing immediately lent a hand, directly activating his talent to keep Dian Wei’s blood in its current state.

After drawing a large tube of blood, both men looked somewhat serious. With their extended medical talents, they could both perceive the ongoing changes within the blood tube, so both dared not delay, simultaneously reinforcing their talents and then saluted everyone.

"General Dian, try to maintain the state of unlocking the body’s constraints. After you unlock them, a certain substance is born in your body, which continuously permanently strengthens your body, gradually allowing your body to adapt to a complete liberation of body functions." Hua Tuo stated solemnly to Dian Wei.

"What you need now is not conventional training, your body needs adaptation. This substance is continuously modifying your body," Zhang Zhongjing also stated with a solemn expression.

"In other words, every time you unlock the body’s constraints, your physical quality will improve to some extent, and you’ll progress further down this path until you fully adapt to this state." Hua Tuo staring at the tube of blood, both he and Zhang Zhongjing could perceive that substance.

"Does this mean he will keep getting stronger without training?" Zhao Yun asked curiously.

"I’m afraid so. Once his body enters this state, it will continuously secrete this substance, greatly enhancing physical qualities in the short term while also permanently strengthening, with no side effects. It’s likely a naturally secreted substance after the body grows to its limit." Hua Tuo speculated.

"So, unexpectedly, everyone may have this substance hidden in the body, just needing some trigger condition." Zhang Zhongjing said, "We will take our leave first and may need General Dian’s assistance again later."

Dian Wei nodded, and as for the needle hole in his arm, it had completely healed now, with recovery power almost catching up to the super recovery speed born from disrupting body balance like Zhou Tai.

"It’s truly unbelievable." After Hua Tuo and Zhang Zhongjing left, Sima Lang looked at Dian Wei with amazement, "Didn’t expect there’s a way to grow stronger without training. Haha, maybe I can become like General Dian someday."

"You’re overthinking." Chen Xi pressed his hand on Sima Lang’s shoulder, "I say, cousin, your imagination is quite something."

Chen Xi roughly guessed the type of hormone involved. However, that kind of hormone actually harms normal people significantly, while growth does require such hormones. The body secretes an extremely trace amount of this hormone spontaneously, and as for Dian Wei, it’s likely his tolerance is much higher.

[Yet, after Heaven and Earth Essence enhancement, will this hormone change? Speaking of nurturing changes substance structure, at Dian Wei’s level, he might instinctively change the hormone structure, even subconsciously strengthen the desired effects.]Chen Xi thought silently, though unsure of what Hua Tuo and Zhang Zhongjing could discover.
